Question

I have an image button which should toggle the calendar whose visibility is set to false initially.
This is the Page_Load Code:

Calendar3.EnableViewState = false;

if (!IsPostBack)
{
    BindData();
}

This is on imagebutton click.

 protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
 {
     if (Calendar3.Visible == false)
         Calendar3.Visible = true;
     else
         Calendar3.Visible = false;
 }

The calendar becomes visible on the first click and I can’t hide it if I click on the button again. How can I change visibility property of calendar control work on every button click.

PS: I’m using the calendar control and the imagebutton inside an update panel to take of postback and when I try to debug, the visibility property is set to default value from the calendar tag on every page_load.

Thanks

Remove the line

Calendar3.EnableViewState = false;

and you can simply write the button click event as:

Calendar3.Visible = !Calendar3.Visible; //toggle effect
