Textbox value gone when postback occurs

Question

Hi all I am having ajax tab container and gridview in each tab. Gridview contains columns in which one column is dropdown box and another column is text box. In page _ Init Tabs are added to tab container and in pageload gridview is created inside each tab. If user changes the dropdown value and enters some value in the textbox before the postback of drop down is complete due to reload value entered in textbox will vanish. Is there some way to prevent user from entering the value in textbox column before the postback of dropdowncolumn is complete? Regards Simi J

You could actually try one more if these does not work.. have a hidden field and assign the value before postback (in the dropdown selectedindex changed event) and read from that and assign to the textbox in page load..

I can't set the enabled property because on post back the object is not existing. Its rerendered. I will try will enableviewstate. But i guess it will also have the same problem.

You could set the enabled property to false or else if you wish to put the value after postback set enableviewstate property to true to the textbox so that even after postback the value is retained
