[Solved] IsVisible DataBoundColumn is not accessible

[Ernesto]

Hi,
I would like to not show a column, but I would like to have it available on the client side.
When I set the DataColum property IsVisible="false", The cell is not available. How do I get a handle of that cell?

The following code is what I am doing.

 

 

private void Method1_RowLoaded(object sender, RowLoadedEventArgs ea)

{

 

 

 

GridViewDataControl dataControl = ea.GridViewDataControl as GridViewDataControl;

 

GridViewRowItem row = ea.Row;

 

object content = row.Cells[0].Content;

 

if (content is TextBlock)

{

 

 

 

TextBlock actionCell = content as TextBlock;  

 

 

 

if (actionCell.Text.ToString() == "True")

row.FontStyle = FontStyles.Italic; 

 

}

 

 

 

 

 

<DataColumn UniqueName="IsActionOrExecution" Width="1" IsVisible ="False" >

 

<DataColumn.CellTemplate >

 

    <DataTemplate > 
    <TextBlock Text="{Binding IsActionOrExecution }" />

 

    </DataTemplate> 

</DataColumn.CellTemplate >

 

</DataColumn >

Thanks,
E.

Hello Ernesto,

 

  Data for columns with IsVisible property set to False cannot be accessed from the Cells collection but for your scenario it is better to directly operate on the data level, as shown below:

<telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn IsVisible="False" Width="200" Header="IsTrue?" IsSortable="False" IsReorderable="False" IsGroupable="False" IsFilterable="False" ShowDistinctFilters="False" DataMemberBinding="{Binding Property2, Mode=TwoWay}">
            <telerik:GridViewDataColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Married}"/>
                    </DataTemplate>
                </telerik:GridViewDataColumn.CellTemplate>
            </telerik:GridViewDataColumn>
    <telerik:GridViewDataColumn Width="200" Header="First Name" IsSortable="False" IsReorderable="False" IsGroupable="False" IsFilterable="False" ShowDistinctFilters="False" DataMemberBinding="{Binding FirstName, Mode=TwoWay}"/>
    <telerik:GridViewDataColumn Width="200" Header="Last Name" IsSortable="False" IsReorderable="False" IsGroupable="False" IsFilterable="False" ShowDistinctFilters="False" DataMemberBinding="{Binding LastName, Mode=TwoWay}"/>
</telerik:RadGridView.Columns>

        {
            // TODO: Add event handler implementation here.
         if (e.Row is GridViewRow &&!(e.Row is GridViewNewRow) )
     {
           var obj=(e.Row.DataContext as Employee).Married;
            if(obj==true)
            {
                e.Row.Background=new SolidColorBrush(Colors.Red);
            }
            else
            {
                e.Row.Background=new SolidColorBrush(Colors.Yellow);
            }

     }

  Even better approach is to use Style Selectors as demonstrated on this online demo.

Please let me know how this works for you.
