Hello.
I have a radgrid that has radtabs and the multipage. I want to use a dropdown in the radfilter for some of the fields, so that:
a) the initial page load is the default load
b) from the filter selection, using the example from Grid / Filtering Template Columns, http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx, the grid will bind according to the selection.
I read all of the tutorials on customizing the filters, but nothing seems to work correctly for me. I followed the tutorial and I am not getting the results. If anything, I am not ghetting an error on the RadMultiPage Control. I created the FilterTemplateColumns.cs class. I am not sure how to register that class correctly in my file.
At the top of my .aspx page, I have the following, whcih is not correct:
The class was created and saved in my App_code folder.
The following is the grid where I am receiving the "object reference not set to an instance of an object"
What can I do to prevent this error? I want to use other dropdowns in the filters. Also, do I need to add <filter parameters> in my sqldatasource?
Thank you for your help.
