Dynamic codebehind ColumnGroups and Excel Export

[tony]

Hi,

I just got the newest version and was pleased to see the addition of merged column headers. However, We currently generate our ColumnGroups after a service call and while the columns show up properly, the groupColumn always shows up blank.

public MainPage()
 {
 InitializeComponent();

 service.ServiceClient sc = newService.ServiceClient();
 sc.SaveFileCompleted += new EventHandler<service.SaveFileCompletedEventArgs>(sc_SaveFileCompleted);
 sc.SaveFileAsync();
}

void sc_SaveFileCompleted(object sender, fileSaveService.SaveFileCompletedEventArgs e)
{
 RadGridView.ColumnGroups.Add(new Telerik.Windows.Controls.GridViewColumnGroup() { Name = "Vehicle_Info", Header = "Vehicle info" });
 RadGridView.ColumnGroups.Add(new Telerik.Windows.Controls.GridViewColumnGroup() { Name = "Dimensions", Header = "Dimensions" });

//Further Column Definition

}

This will draw the columns properly, but will fail to render the columnGroups.

I have attached a screenshot of what gets rendered.

Secondly, we are trying to export from the grid with merged column headers and it doesnt seem to render the merged columns, I was wondering how we can get the merged columns as part of our excel export?

Thanks!
Tony

Hi Tony,

Thank you for the feedback ! I am treating these as feature requests . Both are reasonable - adding groups runtime should result in properly rendered column groups  and column groups should be included when exporting data.

We have a service pack release planned within two weeks. I will do my best to have the improvements for you included.

One more time thanks for the valuable feedback. I am updating your Telerik points.

All the best,

Hello Pavel

The merged column headers does not yet export. Is it possible to get an estimated time of when we can expect this feature. 

I am using the newest internal build at this moment: RadControls_for_Silverlight4_2011_3_1413.

Thank you

Hello Frodi,

In a few hours you should be able to download our new official release (Q1 2012) which does include the feature promised earlier.

Hi,

I have a scenario where i need to create GridViewColumnGroup dynamically from my Viewmodel. I have few fields to be displayed in the header like
'Report Name':testReport
'Total amount Collected':10000
and etc.
Report Name and Total amount Collected values will be bound to the group header only at the run time. How can i achieve this scenario ? Can anyone help with this ?

Hi Arun,

I am not exactly sure what your requirements are. However all of the Properties available in XAML are available in the code behind too. You can add and remove Column Groups through the ColumnGroups Collection in RadGrdiView. 

Hope this helps.
