asp.net c# FindControl inside Reapater inside HTML table return null-CodePudding

I have a repeater inside the HTML table the problem is I'm trying to get label value on item date bound event but it always returns null I tried to use the same code without the HTML table its working fine so is there a way to get value while I'm using an HTML table

 <table  >
                                    <asp:Repeater  ID="DtImages" OnItemDataBound="DtImages_ItemDataBound" runat="server">
                                        <HeaderTemplate>
                                            <thead>
                                                <tr>
                                                    <th>Image</th>

             protected void DtImages_ItemDataBound(object sender,RepeaterItemEventArgs e)
    {

                        Label Pinned =(Label) e.Item.FindControl("lblProId")  ;// its return null
                // some codes

        }

CodePudding user response：

When the repeater data bind triggers, headers, alternating rows, and a data row all are feed to that routine.

So, you have to do this:

    protected void DtImages_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if ((e.Item.ItemType == ListItemType.Item) |
            (e.Item.ItemType == ListItemType.AlternatingItem))
        {
            Label Pinned = (Label)e.Item.FindControl("lblProId");                
        }
    }
