Add new Attributes at runtime to Repeater control

After the datasource has been assigned to a repeater control, is it possible, in the C# code behind, to add attributes to certain LinkButtons (the repeater is a list of LinkButtons)?

LinkButton.Attributes.Add("onClick", "return confirm('Are you sure you want to delete this item (and sub items if this is a folder)?');");

but only on certain ones, not on all of them

Thanks!

The simplest solution would be to replace your repeater of LinkButtons into a bullited list of LinkButtons, this will enable you to (from server side code) itterate over the BulitedList Controls item collection, see below for an example: -

<asp:BulletedList ID="BulletedList1" runat="server" DisplayMode="LinkButton">
</asp:BulletedList>

As long as I could still build it from a database that would be fine.

Not very familiar with a bulleted list or the advantages over a repeater.

Why wouldn't a repeater work?

McExp

Apologies, The BullitedList will not give you the functionality you require. It does give you a neat way of creating a list of link buttons however it doens't expose them to allow you to apply an on click function.

I'll work up an example using the Repeater class.

McExp:

Does your solution allow me to apply the Attribute to specific rows of the repeater?

McExp

Yes, what is your criteria?

All you need to do is add a conditional statment around the "lbTempTest.Attributes.Add" statment

I think my criteria will be based on LinkButton "Text"

If "LinkButton.Text == <some value>" then add attribute

That sort of thing.

I think what you have already provided me should be enough!!

I'll know for sure when I get in to work on Monday.

For my future reference:

protected void FirstUseStepsStatus_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lbTempTest = e.Item.FindControl("LinkButtonStep") as LinkButton;
if (lbTempTest != null)
{
if (lbTempTest.CommandArgument == "2")
{
lbTempTest.Attributes.Add("onClick", "return confirm('Do you want to add another Debt Item?');");
}
}
}
