Asp:repeater onclick event not working with Sifenity 4.1

Hi Team,
I am currently working with sitefinity 4.1 and i have created a user control which displays list of item in a Repeater control and onclick of that item, it will add the text to a Textbox control out side the Repeater control. i have integrated this user control in to sifenity 4.1.
Now i have created a new page using sitefinity 4.1 and add this user control in to that page, and browsed the page. The onclick event in the repeater control is not working.
below the code for the repeater.
<asp:Repeater ID="rptTags" runat="server" DataSourceID="sqldsTags"
                            OnItemDataBound="rptTags_ItemDataBound">
                            <ItemTemplate>                                
                                <asp:Button BackColor="Transparent" ID="btnTag" onClick="btnTag_Click" runat="server" Text='<%# Eval("TagValue") %>' BorderStyle="None" CssClass="sidebar-item-tag"  />                            
                            </ItemTemplate>
                        </asp:Repeater>
 <telerik:RadTextBox ID="rtbTagInput" CssClass="mtbTag" runat="server" Width="100%" />

code added in CS file
 protected void btnTag_Click(object sender, EventArgs e)
   
        Button btnTag = (Button)sender;
        taglist = rtbTagInput.Text;

        if (btnTag.BackColor == System.Drawing.Color.Yellow)
       
            //remove tag from list
            taglist = taglist.Replace(btnTag.Text, "").Trim();
       
        else
       
            //add tag to list
            if (taglist == "")
                taglist = btnTag.Text;
            else
           
                taglist += " " + btnTag.Text;
           
       
        rtbTagInput.Text = taglist;
        rptTags.DataBind();
   

i think we need to add the parameter EnableEventValidation="true" at top of the page.
can you please suggest how can i add this parameter while creating pages from sitefinity 4.1

Hello Shekar,

Could you check whether you enabled the view state of the page?

All the best,

Thanks for your quick response.

NO, EnableViewState is not enabled on the user control page, i think by default it will be true.

Thanks
