postback

I have an aspx page that postsback when it should not. there are two text boxes, two listboxes and two buttons on the page. if at any-point the enter key is pressed the first button is given focus and "clicked" resulting in a loss of selection within the listboxes. How do I disable this? there are tons of tutorials on how to capture the enter button and execute a method but I could find one on how to simply disable the neat "let me grab the first button I find and click it" feature mentioned above. You could set the DefaultButton on the Form or a Panel. This way you have full control what

How to detect/track/check postback in javascript(e.g in asp.net Page.isPostBack())?

Using MVC puts the developer much closer to the generated HTML, lends itself more

But on the IE10 standard mode, it is giving below error. SCRIPT5009: '__doPostBack' is undefined [I have created a demo project with a simple asp:link button that redirects to another page.] Tried the solution, but didn't work for me Can anyone suggest fix for this? There is apparently a bug in the browser definition files that shipped with .NET 2.0 and .NET 4. The definition files do not cater for IE10 as a

I have a form that is being dynamically built depending on user selection using Ajax (built in .NET Ajax with UpdatePanel). how can I insert a "standard" ajax loading icon (maybe have it attached to the mouse pointer) while the postback is happening then remove it when the post back is finished? I do have the AjaxToolKit installed if that helps. use updateprogress of tool kit :hope this will help you <asp:updatepanel id="ResultsUpdatePanel" runat="server"> <contenttemplate> <div style="text-align:center;"> <asp:updateprogress id="UpdateProgress1" runat="server" associatedupdatepanelid=
