Hey guys I know it had been discussed so much but I still don't get it working.
What I need is to filter a gridview by a few dropdown lists and the main idea is to "continue" filtering the gridview. I mean, when I select value from ddl1, then the ddl2 is filtered according to the selected value in ddl1 and so forth
Also called cascading dropdown list but I don't want to (can not) use Ajax Control Toolkit...
Any other solutions to that? Maybe the method
protected void DropDownList2_SelectedIndexChanged(...)
can do this but I don't know how to use it.
Please help Thanks in advance.
