I thought this would be straight-forward, and maybe it is -- I am probably missing something obvious. I have a RadGrid that has DropDownList inside a GridTemplateColumn.
I need the DropDownList datasource to have a parameter from a cell value on the selected row. The DataKeyName also contains the same value that could be used as a parm.
When I try to use a ControlParameter from the Grid itself as shown above, I get this error:
Could not find control 'RadGridTestsInstruments' in ControlParameter 'set_test_id'.
If I just use a Parameter from the Grid itself as shown above, there is nothing returned.
I am thinking that I should be going this route, but I must not be setting the right field on the Grid and/or dropdown to set the parameter properly.
If I remove the parameter completely, I get data, but from all rows in the Grid, which is incorrect.
Thanks in advance,
