Repeater Help

[baden100]

I have a repeater that displays an alphabetized list.

When the first letter changes, I want to add something like
<br /> <b>[LETTER]</b> <br />

thus:

A
aword
anotherword
anothernotherword

B
bent
bendover

...



I was thinking of some type of OnItemCreated event handler:

    protected void Repeater1_ItemCreated(object source, RepeaterItemEventArgs e)
    {
        firstLetter = e.Item.DataItem.ToString().Substring(0, 1);
        //Response.Write("Letter: " + firstLetter + "<br>");
        
    }

But I can't quite get this working.

I was looking at

http://www.codeproject.com/aspnet/ObjectRepeater.asp

- but that's too complex of a solution for this.


Suggestions?

declare a global variable that will track the change.



String oldFirstLetter;

protected void Repeater1_ItemCreated(object source, RepeaterItemEventArgs e)
{
firstLetter = e.Item.DataItem.ToString().Substring(0, 1);
if(oldFirstLetter!=firstLetter)
{
oldFirstLetter=firstLetter;
//Write code here to add a new literalcontrol
LiteralControl newCtrl=new LiteralControl("Letter: " + firstLetter + "<br>");
e.Item.Controls.AddAt(0,newCtrl);
}
}


Note:
I am not used to C#, so the code may cotain errors...

Ah,

With a little fandangling, it's working perfectly:

 string oldFirstLetter;

   protected void Repeater1_ItemCreated(object source, RepeaterItemEventArgs e)
    {
        string firstLetter = Convert.ToString(DataBinder.Eval(e.Item.DataItem, "Term")).Substring(0,1);

        if (oldFirstLetter != firstLetter)
        {
            oldFirstLetter = firstLetter;
            //Write code here to add a new literalcontrol
            LiteralControl newCtrl = new LiteralControl("<b>Letter: " + firstLetter + "</b><br>");
            e.Item.Controls.AddAt(0, newCtrl);            
        }
    }
