I just started using Telerik Grid instead of MS based Grid.
I just tried to Add and clear columns dynamically into the grid but I couldn't find the appropirate functions in intellisense.
I tried "this.radResult.Columns.Add(dyncol)" but, I Couldn't find "Add" in intellisense, couldn't find "Clear" method in intellisense as either.

            private void BuildColumns()   
        
            {  
        
               this.radResult.Columns.Clear(); //<-- This method doesnt show in intellisense, neither Add method will show up here   
        
            }

Am I doing anything wrong here?

Problem in RadGridView, when used with pagination

Hello telerik,

I have tried to implement pagination using RadGridview, i have downloaded the latest WPF Q2 SP1 samples.. and looked into the example in GridView -> Performance - > Server page, sort etc...

When i tried to group the columns by dragging the column header on to the header droppable zone, items have been grouped.

but when i tried to change the current page to some other page by clicking any number on the Pagination control and after that when i tried to group the columns, it is throwing exception...

Is this a bug?

Reproduce steps:

1) Launched the C# Samples from Start -> Programs -> Telerik

2) Select Grid View control -> Performance -> Server page, sort etc...Now able to see the radgrid view with pagination on the right panel

3) Click on second page ("2") on the pagination control

4) Drag any column header to group, I have dragged "Company Name" column.. Now error is thrown...

When i tried to debug i fournd the following as the inner exception:

"Unable to cast object of type 'Telerik.Windows.Examples.Customer' to type 'Telerik.Windows.Data.IGroup'."

Thanks,

Kranthi

themes for Q2 is broken

the predefined themes for q2 is broken. We installed Q2 and themes no longer display for the grid. We uninstalled Q2 and went back to Q1 and themes display fine. Have not tried the work around for winforms of setting the theme from code in the initialize event. Will let you know.

I want to filter my child grid
when I watch the DateView dv it is filtered
but in the child grid I still see all the rows and not only the filtered rows
this is my code

    
             private void OnChildGridLoaded(object sender, RoutedEventArgs e)  
        
                    {  
        
                        // Pull data from the detail table based on the relation.  
        
                        var dataRowView = (DataRowView)((RadGridView)sender).ParentRow.DataContext;

Datepicker setDate

Hi everyone,

If found something strange about the way setDate behaves when passing a date object in parameter.

I use the fonction like this:
var date = new Date();
alert(date); // Tue Aug 25 2009 16:58:26 CTU+0800
$('#datepicker).datepicker('setDate', date);
alert(date); // Tue Aug 25 2009 16:58:57 CTU+0800

Why does the setDate function modifies the date object? Is this normal?
How to modifiy format of the date ,eg 'yy-MM-dd'?
I didn't find anything about this subject on the website.

Thanks a lot

Request: More built-in themes

I would like to make a request for more built-in themes. Ideally, I would like to see a good 20 or 30 of them to choose from instead of 4. I know it just came out, so I'm glad it at least has four, but I'd rather not have to sit in Blend and mess around with customizing the template unless I really have to. It looks like with templates, you can basically do anything you want with the chart...the xaml just really gets complicated (I'm no wpf expert yet though, so maybe it is just a learning curve I need to get over).

On a side note, my post about hiding the legend just disappeared completely from the forum. Also, subscribing to threads seems to not work. Maybe the new website changes caused some glitches.

Rad Drag and Drop example

I was wondering if there if someone has an example of using the rad drag and drop to rearrange items in a WPF list box. I found the example to drag and drop from one control to another, but I am looking for direction on how to drag and drop to rearrange items in a single control.

Thanks
