How to use the GridRecordNavigator control in windows form SfDataGrid

About the sample

This example illustrates how to use the GridRecordNavigator control in windows form DataGrid.

By default, SfDataGrid does not support for GridRecordNavigationBar. But we can achieve this by change the selection based on navigation buttons.

Navigate to next row

private void next_Click(object sender, EventArgs e)
{
    var tableControl = this.sfDataGrid1.TableControl;
    if (this.sfDataGrid1.SelectedIndex > -1 && (this.sfDataGrid1.TableControl.ResolveToRowIndex(this.sfDataGrid1.SelectedIndex + 1) != sfDataGrid1.RowCount))
    {
        this.sfDataGrid1.SelectedIndex = this.sfDataGrid1.SelectedIndex + 1;
        selectedIndex = this.sfDataGrid1.SelectedIndex + 1;
        this.sfDataGrid1.TableControl.ScrollRows.ScrollInView(this.sfDataGrid1.CurrentCell.RowIndex);
        this.sfDataGrid1.TableControl.UpdateScrollBars();
        label1.Text = "Record \t" + selectedIndex.ToString() + "of" + (this.sfDataGrid1.TableControl.ScrollRows.LineCount - this.sfDataGrid1.TableControl.ScrollRows.HeaderLineCount);
    }
}

Navigate to previous row

private void previous_Click(object sender, EventArgs e)
{
    if (this.sfDataGrid1.SelectedIndex > 0)
        this.sfDataGrid1.SelectedIndex = this.sfDataGrid1.SelectedIndex - 1;
    selectedIndex = this.sfDataGrid1.SelectedIndex +1;
    this.sfDataGrid1.TableControl.ScrollRows.ScrollInView(this.sfDataGrid1.CurrentCell.RowIndex);
    this.sfDataGrid1.TableControl.UpdateScrollBars();
    label1.Text = "Record \t" + selectedIndex.ToString() + "of" + (this.sfDataGrid1.TableControl.ScrollRows.LineCount - this.sfDataGrid1.TableControl.ScrollRows.HeaderLineCount);
}

Navigate to last row

private void last_Click(object sender, EventArgs e)
{
    var getLastRowIndex = typeof(SelectionHelper).GetMethod("GetLastRowIndex", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static);
    var lastRowIndex = (int)getLastRowIndex.Invoke(typeof(SelectionHelper), new object[] { this.sfDataGrid1 });

    this.sfDataGrid1.SelectedIndex = lastRowIndex - 1;

    this.sfDataGrid1.TableControl.ScrollRows.ScrollInView(this.sfDataGrid1.SelectedIndex);
    this.sfDataGrid1.TableControl.UpdateScrollBars();

    label1.Text = "Record \t" + lastRowIndex.ToString() + "of" + (this.sfDataGrid1.TableControl.ScrollRows.LineCount - this.sfDataGrid1.TableControl.ScrollRows.HeaderLineCount);

} 

Navigate to first row

private void first_Click(object sender, EventArgs e)
{
    var getFirstDataRowIndex = typeof(SelectionHelper).GetMethod("GetFirstRowIndex", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static);
    var firstRowIndex = (int)getFirstDataRowIndex.Invoke(typeof(SelectionHelper), new object[] { this.sfDataGrid1 });

    this.sfDataGrid1.SelectedIndex = firstRowIndex - 1;

    this.sfDataGrid1.TableControl.ScrollRows.ScrollInView(this.sfDataGrid1.SelectedIndex);
    this.sfDataGrid1.TableControl.UpdateScrollBars();
    label1.Text = "Record \t" + firstRowIndex.ToString() + "of" + (this.sfDataGrid1.TableControl.ScrollRows.LineCount - this.sfDataGrid1.TableControl.ScrollRows.HeaderLineCount);
}
