Double postback on filtering by Enter key in Opera.

[Neadequant]

Hello.

I use radGrid to show some data on a web page.

The radGrid is placed into an AJAX panel.

Some of the databound columns of the grid have AutoPostbackOnFilter set to 'true' and CurrentFilterFunction set to 'Contains'.

No filter template is specified. So default filters are used.

When using IE 8,9 and Chrome everything is OK, but there is a problem in Opera (10.62).

When I type some text in the filter field and then press Enter key, radGrid makes 2 ajax-postbacks instead of 1.

KeyPress event is not fired on Enter key, but 2 OnCommand events are fired with commandName='Filter'.

So, the question is: How to avoid such behaviour and make only one ajax-postback on filtering by Enter key.

I tried to find the answer on telerik forums and in demos, but still have no success.

You can see the described behaviour on radGrid demo:

Type 'Vins' in ShipName column filter and press Enter. You will see that 2 ajax-postbacks occured.

Hi Neadequant,

I followed your steps and I was able to replicate the issue. However it is replicable without RadControls on the page as well. It seems that it is Opera browser behavior to initiate two postbacks when enter is pressed for input controls with AutoPostBack set to true.

You can try the attached sample and see how it goes.

However I have forwarded this issue to out developers so they can see if we can address the problem somehow.
