Cannot set selected style for LinkButton which inside a repeater control

Question

I have a repeater control in my aspx page:

 <asp:Repeater ID="Repeater1" runat="server">
                    <ItemTemplate>
                        <table>
                            <tr>
                                <td>
                                    <img src="pic/iconnew.jpg"/>
                                </td>
                                <td>
                                    <asp:LinkButton ID="linkbtTitle" runat="server" Text='<%#Eval("title")%>' CommandArgument='<%#Eval("id_notic")%>' OnCommand="linkbtTitle_Click" OnClick="Buttonlink_Click" ></asp:LinkButton>
                                </td>
                                <td>
                                    <asp:Label ID="LabelTime" runat="server" Text='<%#Eval("time")%>' CssClass="TimeMessage" ></asp:Label> 
                                </td>
                            </tr>
                        </table>
                    </ItemTemplate>
                </asp:Repeater>

I want to set the selected style for linkbutton linkbtTitle by Buttonlink_Click event:

<script runat="server">  
    protected void Buttonlink_Click(object sender, System.EventArgs e)  
    {
        linkbtTitle.ForeColor = System.Drawing.Color.HotPink;  
    }  

</script> 

But it has an error, cannot resolve symbol linkbtTitle , why??? Just because the linkbutton is inside the Repeater so I cannot access it by that way above.

How???, help!!!

Answer 1

A repeater is one of the web-databound controls that, well, it repeats items. So there are normally more than one item. That's why you cannot access it directly. It sits in a different NamingContainer which is the RepeaterItem of the repeater.

However, the control that raised an event is always the sender argument. So you just need to cast it:

protected void Buttonlink_Click(object sender, System.EventArgs e)  
{
    LinkButton linkbtTitle =  (LinkButton ) sender;       
    linkbtTitle.ForeColor = System.Drawing.Color.HotPink;  
}
