Hi Nikola,

In my sample, I'm using Data Context that automatically built from LINQ to SQL Classes item (dbml). You can see the connection definition in Northwind.designer.cs inside Northwind.dbml. You can use aspx with WebMethod like you mentioned above. You can also define the stored procedure for data retrieval inside it as long as you can access the custom class in WebMethod to get the data. For references, you can look the sample in our WebCombo sample about client binding. And to refresh the value inside ResultBox, you can put the same way like in my sample.

WebCombo2.IsDirty = true;
WebCombo2.NeedClearList = true;
WebCombo2.Values = null;
WebCombo2.ClearSelection();
WebCombo2.RefreshValueItems();

Hope this helps.

Regards,
Bernard

Hi,

I tried to replicate your problem in your local end. But unfortunately, this matter doesn't happen in our local end. Whether the AllowFilter set to Yes or No, the popup still open and it won't show any error like you mentioned before. Could you tell us you WebGrid version and build? And is there any sample or steps to reproduce this error in our local end? Look forward to hear any feedback so I can help you further.

Regards,
Bernard

Hi,

Actually, there are no methods to find WebCombo inside used pages. The only way to do this is by listing all the WebCombo pages inside your code.
