Control Request: DockPanel Resizer - Vote if you want it.

brianlagunas[CodePlex]
A DockPanel Resizer would be a very helpful addition to the toolkit. There is a control on codeproject for this, but it would be good to have a streamlined control complying with WPF development guidelines in the toolkit.

DateTimeUpDown NullReferenceException

mieliespoor[CodePlex]
I have come across a nasty bug - I think.
nbsp
When you set the value of the DateTimeUpDown to null (dtTime.Value = null;) a NullReferenceException is thrown.
nbsp
If this is not the correct way to clear the value of the control, then I am wrong, but it should then check for null values to ensure that the value is not null.
nbsp
The Exception occurrs in private void ParseValueIntoDateTimeInfo() line 324 -gt DateTime date = DateTime.Parse(Value.ToString()); A null value cannot be converted to string...
nbsp
I changed the method as follows:
string text = string.Empty;
nbsp
_dateTimeInfoList.ForEach(info =gt
{
if (Value == null)
{
info = null;
}
else if (info.Format == null)
{
info.StartPosition = text.Length;
info.Length = info.Content.Length;
text += info.Content;
}
else
{
DateTime date = DateTime.Parse(Value.ToString());
info.StartPosition = text.Length;
info.Content = date.ToString(info.Format, DateTimeFormatInfo);
info.Length = info.Content.Length;
text += info.Content;
}
});
nbsp
I don't know if this is actually the correct way in doing it, but it worked for me in what I am doing with the control

Object not set error in ColorPicker

krystynek[CodePlex]
Hello, I have a problem with ColorPicker in my sollution. I attach source code from Codeplex and debug source code and then I see, that property SetCelectedColor is call previously than method OnApplyTemplate. In method SetCelectedColor is called method
UpdateColorShadeSelectorPosition and in this methos is setting _spectrumSlider.Value = hsv.H;. Object _spectrumSlider is null, because is set on method OnApplyTemplate.
My workaround is set _spectrumSlider and other values in constructor. And my question: Why i have this behaviour and can you repairt this to next release?
nbsp
Thanks. Pavel

MaskedTextBox doesn't work when used in a template that is used by DataGridTemplateColumn’s CellEditingTemplate Property

BaMusaSoft[CodePlex]
I’m using MaskedTextBox in two templates that is used as template for CellEditingTemplate And CellTemplate Properties of DataGridTemplateColumn; when program run, the cell show the text correctly and that means the CellTemplate is function correctly, but
when the cell get’s focus and start editing the content mask disappear and no letter’s show during edit. After I navigate away from the cell text show up again
Here a snippt from xaml code:
ltDataTemplate x:Key=quotGridCellEditingquotgt
ltwpfExtended:MaskedTextBox Mask=quot## /##/ ####quot Value=quot{Binding Path=DateDue}quot/gt
lt/DataTemplategt
nbsp
ltDataTemplate x:Key=quotGridCellTemplatequotgt
ltwpfExtended:MaskedTextBox Mask=quot## /##/ ####quot Value=quot{Binding Path=DateDue}quot/gt

Control Request: DockManager

Great project. I found this over the weekend. Is this supported by Microsoft similar to regular WPF Toolkit? If so, is there plans on combining the 2 kits in the future? I would like to see a DockManager control added. Thanks again.

ChildWindow: Setting Width limits the width of the overlay.

Whe setting the width of the ChildWindow control, the overlay is using the same width. This should not be the case. The width of the ChildWindow should not affect the overlay.

A bug in NumericUpDown

brianlagunas[CodePlex]
Great job! I encountered what appears to be a bug in NumericUpDown. When initial Value is the same as Maximum, Spinner button still allows an increase by 1. To fix it, I added to OnIncrement() the following test preceding actual increment: if (Value lt
Maximum).
nbsp
For completeness, I also added if (Value gt Minimum) preceding decrement in OnDecrement().

BusyIndicator : an other focus issue

gherold[CodePlex]
Just after setting IsBusy = false, it's not possible to focus the inner control.
I tried using the new template with ltContentControl IsTabStop=quotFalsequot Focusable=quotTruequot...
but the problem is still there.
If I do not perform a IsBusy=true / IsBusy= True then my focus works. So, my focus problem is linked to the BusyIndicator

[Question] Do you accept pull requests?

And what are the policies?

RichTextBox and custom TextFormatter when used in a DataTemplate and listbox, SetText not called

codingoptions[CodePlex]
When the RichTextBox control and a custom TextFormatter is used in a DataTemplate for a listboxitem, SetText() on the custom TextFormatter isn't called.
nbsp
It seems to work fine when not in a DataTemplate, but when used with a DataTemplate it seems due to the ordering of the way XAML binds it first fires the OnTextPropertyChanged() BEFORE the TextFormatter property on the RTB is set (thus it initially defaults
to creating the default RTFFormatter and calling SetText() on that instead of the custom TextFormatter).
nbsp
Seems there needs to be a way to postpone the initial OnTextPropertyChanged firing and/or fire it again if a TextFormatter is set (optimally it wouldn't fire the first time). As a workaround that works for my scenario although probably not generically the best
solution is to do the latter and call SetText again on the quotsettingquot of the new formatter:
nbsp
public ITextFormatter TextFormatter
{
get
{
if (_textFormatter == null)
_textFormatter = new RtfFormatter(); //default is rtf
nbsp
return _textFormatter;
}
set
{
_textFormatter = value;

// BEGIN CHANGE
_textHasLoaded = false;
_textFormatter.SetText(Document, Text);
_textHasLoaded = true;
// END CHANGE
}
}

ColorPicker: Add default colors

LisaTatum[CodePlex]
Hey Brian,
nbsp
The typical ColorPicker we are used to allow me to pick easily a color I have choosen before by having default colors as colored squares. Prolly 10 are enough.
nbsp
Using your ColorPicker I have to search always the exact same color value by point and click and aha-that-could be the same color :P
nbsp
Havent tried the colorpicker yet but judging your screenshots I see now displayed values like Hex-number or RGB etc. So a default color palette would be useful.

Child Window crashes XBAP

brianlagunas[CodePlex]
@deepakmehta
The program crashes on startup (Stack Overflow).
nbsp
@brianlagunas
quotSo I have looked into it and have found some interesting behavior when dealing with an XBAP. I can probably say that you have specifically set the width or height on the ChildWindow, something like Width=quot250quot. Take that width off and it will
work. But then another issue occurs. The window will not center. This is because for some reason inside an XBAP the parent container has no Height or Width initially. If you hit refresh on your browser then the ChildWIndow will re-center. All these problems
are due to the fact that for some reason the parent has a Height and Width of 0, which means that the ChildWindow cannot poisiton itself, and which also cause your stack overflow exception you saw when setting the Width and/or Height. Honestly I don't know
if this can be fixed, but I will definitely see what I can come up with.quot

Control Request: MediaElement MediaStreamSource

brianlagunas[CodePlex]
One of the strangest omissions in the WPF MediaElement is the ability to set a MediaStreamSource.
nbsp
http://msdn.microsoft.com/en-us/library/system.windows.media.mediastreamsource(VS.95).aspx
nbsp
The MediaStreamSource is a piece of the Silverlight runtime that removes a the influence of a media file's container, giving developers direct access to APIs for manipulating encoded elementary audio and video streams.
nbsp
Why do silverlight web developers have a better multimedia playback tool than
native WPF apps??? Is MS purposefully trying to kill off WPF? Because without such tools we are forced to build/find third party tools/hacks which (especially in multimedia) are often a huge source of pain and suffering.
nbsp
I'm not sure if that is the kind of thing your project aims to tackle. If so, that would seriously rock. However, I think I am mostly just ranting because from all the new stuff in SL and the lack of features in WPF it seems WPF has been left to atrophy while
they pump up quotthe next big thingquot
nbsp

nbsp
Edit: Ughh...and maybe someone at codeplex could work on a rich text editor that works in browsers other than IE!

ArgumentException is thrown when setting IncludeLiterals="False" for MaskedTextBox used inside DataGridTemplateColumn

BaMusaSoft[CodePlex]
When setting IncludeLiterals=quotFalsequot for MaskedTextBox which used as template for CellTemplate Or CellEditingTemplate properties of DataGridTemplateColumn, ArgumentException is thrown with “The Mask value cannot be null or empty.

Feature Request NumericUpDown: validate value against Min/Max and add validation event

brianlagunas[CodePlex]
TryParseInt() sets result to the prior Value if input text is not a number. It would be nice to do it if the input is out of bounds as well. For example,
nbsp
protected override double ParseValue(string text) {
NumberFormatInfo info = NumberFormatInfo.GetInstance(CultureInfo.CurrentCulture);
double result;
if (text.Contains(info.PercentSymbol))
result = TryParcePercent(text, info);
else
result = TryParceDouble(text, info);
return CheckBounds(result);
}

private double CheckBounds(double number) {
    double result = number;
    if (number lt Minimum || number gt Maximum) {
        //the input is out of bounds; now lets reset our value, text, and the text in the textbox
        result = Value;
        TextBox.Text = Text = FormatValue();
    }
    return result;
}

nbsp
In fact, ParseValue() performs a partial input validation. It would be nice to to allow to use the existing validation schemes. Maybe, you could add an additional DependencyProperty IsValidationUsed, and if it set true, allow an user to do her own validation.
nbsp
Thanks a lot,

Feature Request: Numeric Up Down and null/empty value

SeeSharp[CodePlex]
See attached file. It is NumericUpDown with minor changes to support empty values.

Added bool property AllowNullValue Some changes in methods with text lt-gt value conversion Some decimal variables in inner logic of methods replaced to double, because real value in control interface has double type.
NOTE: First of all property AlloNullValue should be set to true, otherwise standard behavior will be used. When user puts null, property Value have value double.NaN and Text property have string.Empty.
If you want use this feature in XAML, you should bind to property NumericUpDown.Text to text representation of view model. Example:
XAML:
xmlns:wpfExt=quotclr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit.Extendedquot

…
ltwpfExt:NumericUpDown AllowNullValue=quotTruequot
Text=quot{Binding ValueAsString, Mode=TwoWay}quot

Maximum=quot{Binding Maximum}quot
FormatString=quot{Binding FormatString}quot/gt

public double? Value{… }
public string ValueAsString
{

{
return Value.HasValue ? Value.Value.ToString() : string.Empty;
}
set
{

}
else
{

if (double.TryParse(value, out v))
Value = v;
else
throw new FormatException(quotCannot convert string to double.quot);

DateTimePicker Invalid UpDown Value Error

I just started using this toolkit and am very new to WPF, so I may be missing something here, anyway I have found an issue with the DateTimePicker when using the up and down arrows (or the mouse wheel) to increment and decrement date values and time values.

If more than 1 time/date value is selected or blank space is highlighted (anything considered invalid to increase/decrease in other words) an exception is thrown stating that a "Nullable object must have a value".

If this is a bug, please can someone fix this issue.

BusyIndicator Focus issue

brianlagunas[CodePlex]
Hey, first of all, the BusyIndicator is great, and I am using it very successfully in my project. I thought I'd tip you off about one minor problem without though, luckily it is easy to fix.
nbsp
I put my UserControl inside a BusyIndicator and everything worked fine except that I noticed when I used the keyboard to tab out of the last control in my UserControl that the whole Window appeared to have focus. After using Snoop I was able to determine that
it the focus was in the Visual Tree of the BusyIndicator itself. I tried setting IsTabStop=False and Focusable=False on the BusyIndicator itself but that didn't fix it.
nbsp
I fixed it by changing the BusyIndicator's ControlTemplate, specifically I added IsTabStop=False and Focusable=False on the ContentControl that is named quotcontentquot. Then my app's keyboard navigation was back to normal.
nbsp
Just a heads up, thanks again for all your work.

DisplayAfter property is TimeSpan, should it be Decimal?

brianlagunas[CodePlex]
When setting the DisplayAfter value in XAML
nbsp
lttoolkit:BusyIndicator x:Name=quotbusyquot Grid.Row=quot1quot IsBusy=quotFalsequot DisplayAfter=quot5quotgt
nbsp
The value is seen as number of days instead of seconds. This is because the data type for DisplayAfter property is TimeSpan and values should be entered as
nbsp
lttoolkit:BusyIndicator x:Name=quotbusyquot Grid.Row=quot1quot IsBusy=quotFalsequot DisplayAfter=quot00:00:05.0quotgt
nbsp
This was the original behavior of the Silverlight control. Suggest changing it to use decimal seconds instead. This would help using the DisplayAfter property declaratively in XAML more intuitive
nbsp
Example:
nbsp
lttoolkit:BusyIndicator x:Name=quotbusyquot Grid.Row=quot1quot IsBusy=quotFalsequot DisplayAfter=quot1.56quotgt
nbsp
Would represent 1.56 seconds.
nbsp
What are your thoughts?

RichTextBox update on Viewmodel property update

brianlagunas[CodePlex]
Hi,
nbsp
Extended WPF Toolkit RichTextbox does not update when the ViewModel Property associated with it is changed in the code-behind file or from any other file. And the same feature works fine with the regular WPF RichTextbox.

I chose toolkit RichTextBox because of its Binding Property and RTF.
nbsp
Below is the sample code for reference:
nbsp
UserControl.xaml
nbsp
lttoolkit:RichTextBox Name=quotrtbTestquot Text=quot{Binding Path=EmployeeName,UpdateSourceTrigger=PropertyChanged}quot Height=quot70quot Width=quot263quot/gt

nbsp

nbsp
Dim emp As Employee = Me.DataContext
nbsp
emp.EmployeeName = quotXYZquot

RichTextBoxFormatBarManager: Focus Bug when using RichTextBox as CellEditor

LisaTatum[CodePlex]
Hello Brian,
nbsp
as I said lately something in your code changes my datagrid behaviour.
nbsp
These 2 lines cause it:
if (!_richTextBox.IsFocused)
_richTextBox.Focus();
nbsp
When I load data into my datagrid having for example 8 rows each a RichTextBox the focus is oddly set to the 3rd RichTextBox therefore the datagrid gets scrolled to the position.
nbsp
Do you know a workaround/fix for that without losing your bug fix?

BusyIndicator: Bad focus handling

The content control for the busy content should not be allowed to get the focus. Add IsTabStop=quotfalsequot Focusable=quotfalsequot to prevent this.
