Question

I have a check box on a page. I want to set it’s enable property from a codebehind method.
I have done this Enabled= '<%#IsSMSEnabled()%>' />

IsSMSEnabled returns true or false depending on some logic.

Check box is alwyas enabled no matter what is returned by IsSMSEnabled()%

Answer 1

The <%# expressions are evaluated at DataBind() time and are not evaluated at all if DataBind() is not called. You can call DataBind() in PreRenderComplete

protected void Page_PreRenderComplete(object sender, EventArgs e)
{
    DataBind();
}
