Question

I have to set a LinkButton’s OnClientClick attribute but I don’t know what this value is until the LinkButton is bound to. I’m trying to set the value when the repeater binds, but I can’t workout how to get the ‘boundItem/dataContext’ value…

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        <asp:LinkButton  Text="HelloWorld" ID="Hyper1" runat="server" OnDataBinding="Repeater1_DataBinding" >
        </asp:LinkButton> 
    </ItemTemplate> 
</asp:Repeater>

protected void Page_Load(object sender, EventArgs e)
{
    var list = new List<TestObject>();
    list.Add(new TestObject() {TestValue = "testing1"});
    list.Add(new TestObject() { TestValue = "testing2" });
    list.Add(new TestObject() { TestValue = "testing3" });

    this.Repeater1.DataSource = list;
    this.Repeater1.DataBind();
}

public void Repeater1_DataBinding(object sender, EventArgs e)
{
    var link = sender as HyperLink;
    //link.DataItem ???
}

Is there anyway to find out what the current rows bound item is?

Maybe you need to use ItemDataBound event. It provides RepeaterItemEventArgs argument which has DataItem available

this.Repeater1.ItemDataBound += Repeater1_ItemDataBound;

void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    var dataItem = e.Item.DataItem;
}
