Hi there, My problem is that in the below code, the SelectedRow property returns nothing. I manually bind items to GridView at runtime and autogeneratecolumns and autogenerateselectbutton properties are true. I think the problem is about having a PostBack when the Select command is clicked. Thanks a lot. Protected Sub GridView1_RowCo...

Hello Everyone, This is weird, but I've been using this method all over my code: I have dropdown lists that I populate client-side, using callbacks and because of this I'm unable to access their selected values from code behind and using a hidden field to store selected value in it. I had no problem retrieving the hidden field's value o...
We are working on an asp website using frames. In the inner frame, default.css is linked. In default.css, a few css-files are imported. On a postback, the css files are not executed. On a 'normal' load, css is executed. In the source of the webpage we do see the reference to default.css. The path is correct. When using in the head o...

What I would like to do is have the user add a new record to the database and popup a JQuery dialog confirming that the new record was saved. I thought this would be a simple exercise. I have a gridview bound to a LINQDataSource to allow the user to view and edit existing records and a textbox and a button to add new codes. In the h...
I have an ascx control loaded inside a panel tied to a modal pop up panel extender. The problem is that an action triggered by the ascx control causes a postback; when the postback completes, the panel controlled by the modal popup extender which contains the custom ascx control disappears. It is merely hidden though with it's default...
Firefox is causing double PostBacks in my asp.net application. IE and Safari do not cause the problem. I have a form for users to fill out that is inside the second View shown in a MultiView. The MultiView is inside an UpdatePanel so the Views are updated via partial page postbacks. Once they are presented the form they hit submit and t...

The problem we have is where a single page has 2 or more pieces of functionality (as an example a screen to capture personal details that includes a postcode lookup for address). With no ability to cha...

Postbacks do not work after the page has been idle for a few seconds, like 30 seconds or less. If I load the page, enter some data, and click the submit button immediately, the postback works perfectly, but if I let the page si...
