Dynamically add multiple controls II 1

[Affleck]

I have a linkButton that when clicked adds a control to a placeholder control collection.

When the user clicks the linkButton one HtmlInputFile control is added, but any subsequent clicks doesn't add any more controls to the placeholder!?

I have the following wired to the click event:

private void addFileUpload_Click(object sender, System.EventArgs e)
{
System.Web.UI.HtmlControls.HtmlInputFile addFile = new System.Web.UI.HtmlControls.HtmlInputFile();
addFile.Name = "addFile"+addFileCount;
addFile.ID = "addFile"+addFileCount;
plc_files.Controls.Add(addFile);
addFileCount++;
}

Any help appreciated.

TIA

I was expecting this to come up!

On your page load you don't create any of the the control. Therefore what happens is:

1) The page loads (no controls created)
2) The user clicks the "add control" button
3) The page loads (no controls created)
4) The control is added from the button click

What you need is some way of identifying which/how many controls have been loaded and make sure they are added from the page load event if it is a subsequent control.

Don't feel foolish - sometimes these things just need a second pair of eyes - I know I've been in that situation myself.
