[Solved] confirm on header control click

[sf]

I have a header control:

<HeaderTemplate>
<asp:LinkButton runat="server" ID="lbSelectAllItems" Text="Select All" CommandName="SelectAllItems" CommandArgument="qualification" ></asp:LinkButton>
</HeaderTemplate>

I tried to add a javascript function in "OnClientClien" property to confirm action.

OnClientClick='return ConfirmSelectItem()'

when I click on the linkbutton at run time i get javascript error "object expected".

any idea what I am doing wrong?

thanks in advance

Hi,

Give a try with the following approach and see whether it helps.

ASPX:

 <HeaderTemplate>
           <asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="return ConfirmSelectItem(this);" >Click</asp:LinkButton>
  </HeaderTemplate>

JS:

<script type="text/javascript" >
function ConfirmSelectItem()
{
 if(confirm('Do you want proceed?'))
   return true;
  else
   return false;
}
</script >

Thanks

Hi sf,

I am not sure what exactly is causing this issue on your end. Can you try adding the onClick client event for the linkbutton dynamically as shown below and see whether it is working.

ASPX:

 <telerik:GridTemplateColumn UniqueName="TempCol" HeaderText="TempCol">
                        <HeaderTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" >Click</asp:LinkButton>
                        </HeaderTemplate>
                        <ItemTemplate>
                            '<%#Eval("ProductName") %>'
                        </ItemTemplate>

                    </telerik:GridTemplateColumn>

CS:

  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridHeaderItem)
        {
            GridHeaderItem header = (GridHeaderItem)e.Item;
            LinkButton lnkbtn = (LinkButton)header["TempCol"].FindControl("LinkButton1");
            lnkbtn.Attributes.Add("OnClick", "return ConfirmSelectItem();");
        }
   }

JS:

function ConfirmSelectItem()
{
 if(confirm('Do you want proceed?'))
   return true;
  else
   return false;
}

Thanks
