I have an asp and a page with two frames. (content,main)
I would like to show the page on a different frame.
Here is what I have:

I am working in C#


void MYSelectedChangeEventHandlerFunction(DropDownList DD)
{
try
{
string address = DD.SelectedItem.Value;
//Response.Redirect("address");
Response.Write(" <script> window.open(address,main); </script> ")
}
catch(Exception ex)
{
DD.Items.Add("Dir Errors Found!");
}
       
}

What AM I doing wrong?
Is there a better way to out put the page to a different frame within the function.
Help!
Thanks, Redirect to different page

}

Check this link:

The code is in VB, but that shouldn't matter.

HTH,

Response.Write(" <script language=javascript>
window.open('" + address + "')</script> ")

Note the single quotes around the double quotes. To load a page in a particular frame, specify the target property of window. Since you want to open in a new window, don't specify it.

I would suggest that you handle this event in the client side, if that is the only thing you are doing. Otherwise you can put the window.open stuff in window.onload , execute it based on a flag that you set in code-behind.

Ras

when using dynamic javascript in .net pages, you're better to use this in codebehind

        dim strScript as string = "<script> " & _ 'any javascript code here, you can put value of dropdownlist or etc...
        "setTimeout('self.close()',2000); " & _
        "</script>"

        RegisterClientScriptBlock("anything", strScript)

this is vb code, but you can easily convert it to c#


hope it works..
