在网格上选中复选框时，GridView行不会被选中或不受影响

Question

I am using WPF Application Form with Telerik Gridview using C#.

In that Gridview i inserted checkboxes using Data template .

Its created but when i click or check the checkbox the current row is not getting selected.

How can i solve this problem?

Please anyone tell me the solution of this problem.

My xaml code for creating checkbox in grid is:

<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
   <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
   <CheckBox Name="CheckBox" IsChecked="{Binding IsSelected,UpdateSourceTrigger=PropertyChanged}" Click="CheckBox_Click" />
   </StackPanel>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>

In that checkbox i have created click event.

And also i want to know the current row number of the CheckBox Placed row in the gridview in checkbox click event . Give me some suggestion for this.

Here My CheckBox Click event Code:

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
    CheckBox selectedCheckbox = (CheckBox)sender;
    //this.selectedCasePackRadGrid -- This is my gridview
    // Here I want to get the selected row number
}

Thanks in Advance.

First of all, I don't see you actually setting the row as Selected anywhere.

Your binding currently is setting a property in your DataContext called IsSelected . If this property actually exists, you can bind it to GridViewRow.IsSelected in a style

<Style TargetType="{x:Type telerik:GridViewRow}">
    <Setter Property="IsSelected" Value="{Binding IsSelected}" />
</Style>

If it doesn't exist in your data object, you need to use a RelativeSource binding to find the GridViewRow and bind to it's IsSelected property

Checked="{Binding RelativeSource={RelativeSource AncestorType={x:Type telerik:GridViewRow}}, Path=IsSelected}"

As for finding the row number, there is no RowIndex property I know of that you can use to find the row number. One alternative is to get the GridView's ItemsSource and call IndexOf(dataobject) , however that does break the separation of MVVM layers

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
    CheckBox checkBox = (CheckBox)sender;
    var dataItem = checkBox.DataContext as MyDataItem;
    var parentDataObject = myGridView.ItemsSource as SomeDataObject;

    if (dataItem == null || parentDataObject == null)
        return;

    var index = parentDataObject.SomeCollection.IndexOf(dataItem);
    // Do something with index
}

There are also other alternatives such as setting AlternationCount to something higher than the the number of rows, and accessing GridViewRow.AlternationIndex , although I don't know if that will work with Telerik's GridView

But perhaps the best thing you could do is evaluate what you actually need the index for, and see if you can use some other alternative to accomplish what you want. For example, if you want to pass the index of the selected row to a button command, it would be better to just pass the SelectedItem as the CommandParameter.
