Hi,
Thank you for reply. I know that I can do it the way you described but the problem is, that each webpart is in different webpartzone. I'd like to click on the item in menu in one webpart in first zone and refresh another webpart in another webpartzone.
I tried to solve it the way described below and I'd like to know your opinion or suggestions how to solve it in better way.
I placed each webpartzone in separate updatepanels. For each updatePanel I dynamically add one textbox (but it probably doesn't matter which type of server control) with display none style and add trigger for this updatepanel (controlValueTrigger) for this textbox and text value.
When user clicks on the link in menu it calls javascript function which change the Text value (specific value for that menu item) and call onchange() event of that textbox in another updatepanel.
I tried this solution on experimental site and it works fine, but when I implemented the same code in my real application it doesn't work. I traced the whole request/response proccess and I found that request is correctly asynchonously sent, response is correctly created and sent back but there is no refresh of the updatepanel on client.
Do you have any ideas where could be the problem or how to solve this in different way?
Thank you
