Web Forms :: Accessing Controls After Redirecting To Same Page On Button Click?
Jan 3, 2011
on my default.aspx page, i have one dropdownlist (which has book types as values e.g. small books, medium books etc.). Then one textbox. And one button named 'Search'. On button click the datagrid shows result by filtering table data with book type and search string that user enter in textbox.
So on 'Search' button click, i want to load the same page with result but with query string like 'Default.aspx?booktype=small' (using response.redirect) if user selects small in dropdown list. The problem is when i click 'Search' button and the page gets loaded again I cannot access dropdownlist values and search string that user has entered. It takes null only when I use,
[Code]....

I had a issue with accessing dynamic controls in destination.aspx, which i had created during runtime while populating them in a panel in source.aspx.
In source.aspx, i generate controls and fill them up in a panel, after that, this page was posted to destination.aspx. however, i am unable to retrieve my controls at the destination page.
Following are some of the ways i had tried.
this does not work at all, i can't cast a control using a request, it only returns me a string.

Is there a way to access the updated text property of a TextBox which is inside a GridView cell when a Wizard controls next or previous buttons are clicked? I have a requirement to not use the edit and/or update buttons on the GridView row. Therefore, I am trying to figure out a way of grabbing the updated values of each TextBox of the GridView on the PostBack. Furthermore, these controls (i.e. Wizard and GridView) are within an AJAX UserControl.

I have a page in which I am not using cache by using this code:
HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
HttpContext.Current.Response.Cache.SetValidUntilExpires(false);
HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Cache.SetNoStore();
Now I want to know: Is there any difference between coming to this page using a proper link or coming back using browser back button, or is there any way to detect this?

I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page. If I check Page.IsValid property on button click event, it returns false. But Validation Summary message doesn't popup. So user doesn't know what's happening. It will not save the information and it won't give the validation message too.
