Running Event Handlers Before Page_load?
Sep 7, 2011I have a problem with running code in the right order. What I am trying to do is updating a session state variable when I press a button. When I run my code it always runs the event handler for the button after my page_load function.The reason why I need to run it after page_load is that, thatI add a line to the textList. Which the loadGui() should add to a table. The table has a remove button for all lines so the loadGui() function can not be added later becuase then the event handler of the remove buttons wont work.
User press the add button which add a row in the TempResponse Session(TempResponse) gets updated loadGui() runs and includes the newly added row
Sub Page_Load()

ASP.NET - Populating The DropDownList DdlItems In The Page_Load Event?
Feb 15, 2010I am populating the DropDownList ddlItems in the Page_Load event. I am then changing the current selection of the DropDownList in the Page_Load event but the dropdownlistbox.SelectedItems aren't firing up. Can anyone please help me? The dropdownlist keeps on repopulating and I cannot stick with one value that I have selected.Here's a screenshot of the problem.I want to have the value LK00260 selected when I PostBack.Instead of having to see "Add New Item" everytime I postback OVER AN OVER AGAIN.
