Question

I have a Repeater Control with various buttons in it.

When the button gets clicked, it needs to disable itself so it cant be clicked again. Working.

However, when I click that button, it needs to enable any other button but it.

So, When I click on it, it needs to disable. When I click on another one, the previous button must enable, and that one must disable.

So for I’ve tried:

Button btnLoad = (Button)e.Item.FindControl("btnLoad");

foreach (Button b in e.Item.Controls.OfType<Button>().Select(c => c).Where(b => b != btnLoad))
{
   b.Enabled = true;
}

btnLoad.Text = "Currently Viewing";
btnLoad.Enabled = false;

But it isnt working. Depending on where I put it, its either leaving all the buttons enabled (But still changing its text), or not doing anything at all.

What do I need to do to make this work?

Edit: The code is found here:

protected void rptPdfList_ItemCommand(object source, RepeaterCommandEventArgs e)

Which is why I use Button btnLoad = (Button)e.Item.FindControl("btnLoad");.

The method is found in :

switch (e.CommandName)
        {
            case "LoadDoc":
                 //Above code
               break;
        }

Assuming you want that code in the Button‘s Click-event handler:

protected void Button_Clicked(Object sender, EventArgs e)
{
    Button thisButton = (Button) sender;
    thisButton.Text = "Currently Viewing";
    RepeaterItem item = (RepeaterItem) thisButton.NamingContainer;
    IEnumerable<Button> buttons = item.Controls.OfType<Button>();
    foreach(var btn in buttons)
    {
        btn.Enabled = btn != thisButton;
    }
}
