ASP.NET Repeater Selection

I have a se开发者_StackOverflowlect button(LinkButton) inside the Repeater.When i select the button that row should be appear in ListView control.But Repeater control does not support DataKey,then how can i achieve this?

You can have hidden field inside repeater and achieve your task as follows:

protected void SelectLink_Click(object sender, EventArgs e)    
{
    RepeaterItem item = (sender as LinkButton).Parent as RepeaterItem;
    HiddenField hdnId = item.FindControl("hdnId") as HiddenField;
    string id = hdnId.Value.ToString();// incase  your id  is  string     
    //..... 
}

What you are looking for is the ItemCommand event of Repeater. It is a kind of key.
