Accessing Repeater DataItem in Button_OnClick event

I have a repeater control bound to a collection of objects. When I fire off the button_onclick event, I need to have access to the dataitem to get the object properties. Here is what I have and my question is how do I access the underlying objects in a repeater in a button_o开发者_Go百科nclick event

protected void OKButton_Click(object sender, EventArgs e)
{
    try
    {
         string selectedValue = Request.Form["repeaterRadioButton"];
        foreach (RepeaterItem item in Repeater1.Items)
        {
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                MyObject myObject = (MyObject)item.DataItem;
                if (!string.IsNullOrEmpty(selectedValue) && selectedValue == myObject.MyProperty)
                {
                     //stuff in here
                } ... rest of code

The dataitem is not retained; it's only used to bind the initial interface, unless you rebind the repeater on every page load. Then you need to give the button a commandname value, and tap into the repeater.itemCommand, which will give you access to the repeater item, where the dataitem property lives.

EDIT: If you need to access items within the repeater, you can do:

foreach (var item in this.rpt.Items)
{
   if (item.DataItem != null) {
      //Do something
   }
}

Are you trying to access one row or the collection of rows?

HTH.
