DropDownList as TemplateColumn filter

[Pether Wiklander]

Hi,

I'm trying to implement a DropDownList as a filter for one of my TemplateColumns I'm not quite there yet.
I want the DropDownList to automatically filter my list whenever I change the value of the DropDownList. Are there any code examples covering this? AutoPostBack whenever I change the selected item in it.

Basically... this is what I want to achieve:

Filtering template columns

...but I can't seem to find the code for how to do it. Please help!

Hi Pether,

Here is a help article which expalins how you can implement filtering with DropDownList instead of a TextBox.

I'm not sure how to add a "All" item. I've tried to set

CurrentFilterFunction = GridKnownFunction.NoFilter;
CurrentFilterValue = String.Empty;

when that item is selected but without any luck. Any suggestions?

Hello Pether,

You also need to set the MasterTableView.FilterExpression property of the grid to an empty string (in order to clear the previously applied filters) and rebind the control invoking its Rebind() method. Review the [Clear filters] button OnClick server handler on this online demo for more details.
