HI

Please find the screen shot

Requirement #1

I have edited the GroupPanleTemplate, to have 2 Texblock's and 2 ComboBox.

Problem 1: Since its GroupPanle, User can drag and Drop Header's over this panel to have grouping in

Radgrid. I dont want such thing to happen.

Solution needed: Instead of GroupPanle, can i have custom panale over the Header. if so provide me

a sample.

Problem 2: I need to find the name's of those

combobox's and add the custom collection from the user and then to have selection changed event

of those combobox's. Based on selection, grid should respond.

for ex: Grid should group based on the selection of Group Combobox. in the same Filter too.

If filtering combox is selected 1st then Grouping should be based on current rows in Grid.

Requirement #2

Edited the VerticalScrollBar, to have 3 button's (Add -> Add New Row, Delete --> Delete Row, Select --> Select Row)

I need to expose events to user for these buttons.

I need to have a panel below the Horizontal Scroll Bar, so that i can have RadPager and associated events to be fired

based on the selection of Pager...

Here is the Xaml Code

combosaboveheader.zip

Hello Prakash,

To avoid confusion , lets address the issues one by one .

So , regarding the comboboxes above the header :

1. Hide the GroupPanel using

 ShowGroupPanel="False" for RadGridView. 
This will prevent the user to group by draging, 
2. Place the combo boxes in a user control .
3. Place that user contol in the tempalte of the grid.

This is demonstrated in the attached project - it has a combo box above the grid header which can be
used to group the grid.

You can place the filtering combo box in the same user control , using exactly the same approach .

In case this point is clear , let me know so we can proceed with the next one .

Hi  
  
1st i need to thank for ur support 
Great Sample. 
  
Adding the Combobox in template is fine. 
  
Here in this sample you have passed the itemsource for the Combo box in the user control's code page directly.. this shouldn't happen since this will be packed as single control and will be consumed by my development team,  
where i need to find the combo box and provide them associated events to them explicitly.  
  
  
RadGridView gridView = this.ParentOfType<RadGridView>(); 
  
ComboBox cbbx = (ComboBox)gridView.FindName("part_GroupByCombo"); 
  
cbbx.ItemsSource = new[] { "ID", "Category", "Description" }; 
  
cbbx.SelectionChanged += new System.Windows.Controls.SelectionChangedEventHandler(cbbx_SelectionChanged); 
  
This can be done? 
  
if so please proceed.. :)
