Question

I am writing a single ASP Form that dynamically changes Div boxes that are visible from mouse clicks on buttons and when text in textboxes is changed in an Ajax container. The problem i have is in the Page_Load function i create all the objects (text boxes, radio buttons, buttons, etc) dynamically from a .csv file template sitting on the asp hosting server. Everytime a postback happens, even within the Ajax window, the Page_Load function is called again and the .csv file is re-read, and all objects are re-created.

I have tried Checking for IsPostback before re-creating any objects but the objects are then nullified as they have never been created. The page is as a completely new page every single time.

Any ideas would be greatly appreciated.

Answer 1

Try using the Page_PreInit event rather than Page_Load to re-create/manipulate your dynamic controls:

protected void Page_PreInit(object sender, EventArgs e)
{
    // create controls here
}
