Filter Grid with Single Click

[Henry Derstine]

I may be missing this because it seems simple. Is there a way to filter immediatey when the filter image is clicked. I will always use only the contains filter and do not need the extra step of the menu from opening. I tried to add a "search" link button in the filter row but I can not get the correct arguments to be passed to the commanditem event. I was thinking I was making it more complicated then i needed to. Thanks for any help

Hello Henry,

I've made small example to illustrate you how to hide the filter image and how to use CurrentFilterFunction and AutoPostBackOnFilter column properties. You can find the example attached.

Thanks, that worked but I figured a different way to do it with the linkbtn.

FYI (In this scenario I am only filtering on one col)-
