Thanks!

I would like to know how it's possible to choose which filters we need. In fact at the beginning, we have NoFilter, Contains, DoesNotContain (too much)... And I would like only Contais and EqualTo. So how it works?

Thank you.

I am attempting to add the new PRINT BUTTON within the RADGRID.  It shows it I change the radgrid RenderMode to lightweight, however this changes some of my design elements and I must keep the RADGRID rendermode as "Classic" - However this eliminate the new PRINT BUTTON from showing/displaying. 

How can I resolve this?

 protected void rd_Dropdown1_SelectedIndexChanged(object sender,EventArgs e)
    {
       //what code is required here to fetch or access dropdown2 control so that i bind it with suitable sqlcommand?


   
        //RadGrid1.DataBind();
    }

How must i bind to my array's to get 2 lines like Attached image file please ?

In the telerik example datasource get only one array OR it is declaratively...

THANKS for your help

Hi,

The text color of my cells is not updated when I call the Rebind() of my RadGrid.

I've implemented my logic as the following :

- I fill my grid datasource in the NeedDataSource event

- I set the style logic in the ItemDataBound event

Then I update my grid source so I call the Rebind() to force the RadGrid to raise NeedDataSource event and ItemDataBound.

My cell value is well updated but the cell style not.

Do you have any ideas ?

Hi, I have a problem with my grid. This grid is showed to the user, in a popup, when he click on a link.

This is my grid:

and this is my RadClientDataSource:

This is my link (created with javascript):

Now, these are the functions that parse to/from my web service:

All works. My Web Service works (I have tried with other grids).

The problem is: the request on the server (performed by the RadClientDataSource, called by the RadGrid) is made on page load.

I want to avoid this, I just want that the grid is loaded, showed on the link click (indeed, I want to pass the id parameter). But I don't know how.

To be more clear, this is the rest of my implementation: the js code for showing/hiding the popup and for set the id.
