Hi All,

Loosing Template column data after adding new row in grid.

Here's my code for issue.

<telerik:RadGridView x:Name="radGridCustomColumns" Margin="0,0,0,10" MaxHeight="400" HeaderRowStyle="{StaticResource BoldHeaderStyle}" RowIndicatorVisibility="Collapsed" telerik:StyleManager.Theme="Windows7" AlternateRowBackground="#EBEFF3" AlternationCount="2" ShowGroupPanel="False" GridLinesVisibility="None" Width="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Top"

ShowColumnFooters="False" CanUserInsertRows="False" IsReadOnly="True" ShowColumnHeaders="True" AutoGenerateColumns="False"

Visibility="Visible" CanUserResizeColumns="False" CanUserFreezeColumns="False" IsFilteringAllowed="False" CanUserSortColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Components" DataMemberBinding="{Binding Components}" Width="12*">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Components}" Width="100" VerticalAlignment="Top" TextWrapping="Wrap" HorizontalAlignment="Left" ToolTipService.ToolTip="{Binding Components}"/>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="UI Columns" UniqueName="UIColumns" Width="14*">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBox Width="150" Height="25" VerticalAlignment="Top" TextWrapping="Wrap" Text="{Binding UIColumns,Mode=TwoWay}" HorizontalAlignment="Left"/>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn UniqueName="Action" Width="5*">

<telerik:GridViewDataColumn.Header>

<TextBlock Text="Actions" TextWrapping="Wrap"/>

</telerik:GridViewDataColumn.Header>

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center">

<Image Name="imgAdd" Source="/QualityTrackingReportModule;component/Images/greenplus.png" MouseLeftButtonDown="imgAdd_MouseLeftButtonDown" Cursor="Hand" Margin="0,0,3,0" Height="16" Width="16" />

<Image Name="imgEdit" Source="/QualityTrackingReportModule;component/Images/Edit.png" Cursor="Hand" Margin="0,0,3,0" Height="16" Width="16" />

<Image Name="imgDelete" Source="/QualityTrackingReportModule;component/Images/Delete.png" Cursor="Hand" Margin="0,0,0,0" Height="16" Width="16" />

</StackPanel>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Here's C# Code :-

namespace QualityTrackingReportModule

{

public partial class QTRMUICustomization : Page

{

public QTRMUICustomization()

{

InitializeComponent();

radGridCustomColumns.EnableColumnVirtualization = false;

radGridCustomColumns.Width = App.Current.Host.Content.ActualWidth - 25;

ObservableCollection<CustomColumns> lst = new ObservableCollection<CustomColumns>();

lst.Add(new CustomColumns { Components = "HDL", UIColumns = "Custom" });

lst.Add(new CustomColumns { Components = "LDL", UIColumns = "Custom" });

lst.Add(new CustomColumns { Components = "Systolic BP", UIColumns = "Static" });

radGridCustomColumns.ItemsSource = lst;

}

private void imgAdd_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)

{

GridViewRow row = ((Image)sender).ParentOfType<GridViewRow>();

row.IsSelected = true;

object newRow = radGridCustomColumns.Items.AddNew();

radGridCustomColumns.Items.Remove(newRow);

int currentIndex = radGridCustomColumns.Items.IndexOf(radGridCustomColumns.SelectedItem);

((IList)radGridCustomColumns.ItemsSource).Insert(currentIndex + 1, newRow);

// Select the new row

radGridCustomColumns.SelectedItem = newRow;

radGridCustomColumns.Items.MoveCurrentTo(newRow);

}

public class CustomColumns

{

public string Components { get; set; }

public string UIColumns { get; set; }

}
