Hiding and showing iframe 1

[arkadia93]

I am using the tree view IE web control and I need to show different iframes depending upon which node in the tree view has been clicked, and if not have been clicking I don't want any iframe to show.

Can anybody help me out with this? I don't know how to show/hide iframes, and if this would be the right way to go about it.


Thanks

If you add runat="server" to any control, you will be able to access it server side.

Great, now how do I make it so that depending upon the node clicking, you view a different page in the iframe?

 

[ca8msm]

Just change the "src" attribute of the iframe when the user clicks the node. This could either be done server side or by using a javascript solution.

When I enter the iframe name in my C#, src is not recognised. I can add src in the .aspx page, but not in the C# page

I am declaring the iframe as a HTML Generic Control if that makes any difference?

 

[ca8msm]

You could try adding it via the controls Attributes.Add method

What would be the syntax for that?

What I mean is, if my iframe is called countdetails, how do I use attributes.add to add a different src for the iframe depending upon what node is clicked?

public void TreeView_SelectedIndexChange(object sender, TreeViewSelectEventArgs e)
{
Label1.Text += e.NewNode.ToString() + " (old Node Index=" + e.OldNode.ToString()+")" ;

switch (e.NewNode.ToString())
{
case "0.0":
countdetail.Visible = true;
countdetail.Attributes.Add...
break;

case "0.1":
countdetail.Visible = true;
countdetail.Attributes.Add...
}
}

If you ever have trouble with what to pass into a method or property, I suggest reading the help files as there is a file for every method, usually with an explanation and example of how they can be used.

Start by doing this here:

Sorry, I'm still not understanding how attributes.add helps me set the src of an iframe...can anybody help?

 

[ca8msm]

Well, if you read the help file, it states that it will "add an attribute to a server control's AttributeCollection object."

As "src" is an attribute of an iframe, this seems like it would be a potential solution.

So it would be like :

countdetail.Attributes.Add("src", "treeview2.aspx");

Apologies, I thought there must be something more to it, I've had problems using Attributes.Add before...


Thanks!

i think you need an "=" after src
