strange behavior for AutoPostbackOnfilter

[Albert Shenker]

If I set AutoPostbackOnFilter="true" and CurrentFilterFunction="StartsWith", then when a user enters some text and hits enter, the grid will be filtered properly. However, I have noticed, if the user enters text, and then decided to use the filter menu, sometimes the grid filters AS SOON AS they click on the filter icon, as opposed to when they select a menu item. Its almost as if clicking on the filter menu icon causes the grid to filter. This does not occur if AutoPostbackOnFilter="False".

I believe this only happens after the user selects a filter function other than "Starts With".. So, the user selects something other, like "Contains", everything work fine. Then they click on the filter menu icon (the filter funciton "Contains" is now different that what is specified in the Grid declaration "CurrentFilterFunction='StartsWith"), and the filter occurs immediately before they even have a chance to selct an option.

Any idea what's going on.

Hi Albert,

This behavior is expected since when you have AutoPostBackOnFilter=true, the grid will filter immediately after the filter box is blurred.

It would seem to me that developers would like to allow users to filter the grid using the filter menu AND by hitting the enter key. The current capability which filters on blur doesn't make this particularly easy as I described below. I might suggest Telerik look into handling the key-press event in the textbox, checking if the enter key was pressed, and filtering on that, rather than on blur. I believe if the filter box were a RadInput, this would be relatively straighforward so I know that Telerik has the capability of achieving this in a built-in fashion. Rather than changing the existing FilterOnPostback fuctionality, it would probably be best just to introduce a new "FilterOnKeyPress" property and allow the user to specify which key(s) will cause it to filter.

Hello Albert,

Thanks for the feedback.

You can easily achieve your requirement with a couple of lines of code. Please, check out the attached sample (note the ProductName column).
