Refreshing a dropdownlist in a FormView Template

Apr 22nd, 2009

I have a FormView InsertItemTemplate which has a databound dropdownlist. The dropdownlist displays a list of names retrieved through a SQL Server stored proc. The user has an option to add a new name to the database by clicking a button next to the dropdownlist. Clicking the button fires a javascript function, which opens a modal window. This "popup" window is where a new name and other pertinent data is entered. When the modal window closes the dropdownlist needs to refresh in order to display the new name (which was just entered in the modal window).

What is the best approach to refresh the dropdownlist? Where and when should a refresh occur (in what event)?

Thanks for your help!

found this:
In your modal

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
 
window.returnValue = "doReload";
window.close();
 
window.returnValue = "doReload";
window.close();

Then in your mainpage

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
 
 
var modal = window.showModal....
if (modal == "doReload") {
   window.location = window.location;
}
 

var modal = window.showModal....
if (modal == "doReload") {
   window.location = window.location;
}

its in c but it can hopefully give you a starting point on where to research!

Please mark this post as 'Solved' if it has helped and fixed your issue.

Hi,

Where did you bind the dropdownlist it have binded the dropdownlist in page load you can use this javascript

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
window.opener.refresh();
window.opener.refresh();

or

You can try like this

in child page

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
   ClientScript.RegisterStartupScript(this.GetType(), "msg", "alert(' Details Added Successfully!');window.close();window.opener.__doPostBack('ChildWindowPostBack', '');", true);
   ClientScript.RegisterStartupScript(this.GetType(), "msg", "alert(' Details Added Successfully!');window.close();window.opener.__doPostBack('ChildWindowPostBack', '');", true);

in parent page:

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
  this.ClientScript.GetPostBackEventReference(this, string.Empty);
 
        if (this.IsPostBack)
        {
            string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];
 
            if (eventTarget == "ChildWindowPostBack")
            {
//bind the dropdownlist
            }
}
}
  this.ClientScript.GetPostBackEventReference(this, string.Empty);

        if (this.IsPostBack)
        {
            string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];

            if (eventTarget == "ChildWindowPostBack")
            {
//bind the dropdownlist
            }
}
}
