Hi,

i was using Q3 2009 and i populate my RadGridView  with a Datatable of Dynamically generated classes.

I used to have one of the Datatable columns with Type "object" which contains a stackpanel with image +Text data and the RadGridView was displaying it fine.
But after i have updated to Q1 2010 the RadGridView just displays the Type Text,

  • Code Used:

    StackPanel contentPanel = new StackPanel() { Orientation = Orientation.Horizontal };

     

     

TextBlock contentText = new TextBlock() { TextAlignment = TextAlignment.Center, Text = "Video"};

 

 

Image contentImage = new Image() { VerticalAlignment = VerticalAlignment.Top, Height = 20, Width = 20 };

 

contentImage.Source =

new BitmapImage(new Uri(@"Images/video.png", UriKind.Relative));

 

contentPanel.Children.Add(contentImage);

contentPanel.Children.Add(contentText);


datatable.Columns.Add(

new DataColumn() { ColumnName = xmlFields.Name.LocalName, DataType = typeof(object) });

 

datarow[xmlFields.Name.LocalName]=contentPanel;
this
.radGridView.ItemsSource = datatable;

 

 

 

All i want is to set the cell content as Image+Text,
Is there a other way to set Customized (Image+Text)Cell content when the columns that are dynamically created?

i have attached a screen shot which explains better..

Kindly do the needful.

Thanks and Regards

Hi,

Please add desired UI elements and/or templates to the grid instead DataTable! You can use CellTemplate and/or CreateCellElement in inherited column to achieve this.

Hi Vlad,

But it was working with Q3 2009 , do i have to change the logics for every version Updates..!
any way,

could you please give an simple example  regarding how to set a cell template programatically(not in Xaml),
because i dosent have Columns created in xaml , they are created at run time.


Thank you

Hi,

You don't have to change your logic for common things however UI as a part of your data layer is a bit unusual - in my opinion this was supported incidentally.

You can assign CellTemplate in exactly the same way as in XAML:

column.CellTemlate = (DataTemplate)this.Resource["YourTemplate"];

If you want to instantiate DataTemplate programmatically you can use XamlReader.Load(). The other option will be (as I said in my previous reply) to inherit from desired column, override CreateCellElement and return desired FrameworkElement.

All the best,

Hi,

i have identified the problem with setting background to TopLeftHeaderCell,

when i have a theme applied to the Application the GridViewHeaderRowStyle is not getting applied.

Example:

when i have 

 

StyleManager.ApplicationTheme = ThemeManager.FromName("Vista");

 

 

the below code is not effective

 

 

<Style x:Key="GridViewHeaderRowStyle" TargetType="gridView:GridViewHeaderRow">

 

 

 

<Setter Property="Background" Value="Red" />

 

 

 

</Style>

how can i fix this?

Hello Dominic Savio maria selvaraj,

I believe this was covered in another forum post of yours. In any case please review this post which illustrates how to go about restyling the header and let me know if you need any additional assistance.

Please lets keep this conversation in only one forum thread.

Greetings,
