Dynamic Update/Delete Link

[L]

hi

I am wondering how do I hide the update link in the RadGrid based on certain conditions.

what i have with this code:

</

EditItemTemplate>

<ItemTemplate>

<a href="#" onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"vourcherid")%>'); return false;">Update</a>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

I want to hide or disable this Update link in the grid when the value is null. Thanks

Hi Lui Nai Wah,

Try with the following approach and see whether it helps.

ASPX:

<a href="#" visible='<%# DataBinder.Eval (Container.DataItem,"vourcherid")!=null?true:false %>' onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"vourcherid")%>'); return false;">Update</a>

Thanks
Princy.

hi

I tried using the sugessted solution and it gave me this error:

Overload resolution failed because no accessible 'ToString' accepts this number of arguments

I tried also:

</

EditItemTemplate>

<ItemTemplate>

<a href="#" visible='<%# IIF(DataBinder.Eval(Container.DataItem,"voucherID") is nothing,True,False)%>' onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"voucherID")%>'); return false;">Update</a>
</ItemTemplate>
</telerik:GridTemplateColumn>

No error but the Update link is still there. Thanks

hi

How do i format the " " in the text property of this label? Thanks

<asp:Label ID="Label2" visible='<%# IIF(DataBinder.Eval (Container.DataItem,"voucherid") is nothing,True,false) %>' runat="server" Text="<a href="#" onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"voucherid")%>'); return false;">Update</a>"></asp:Label>

I first tested with this:

<asp:Label ID="Label2" visible='<%# IIF(DataBinder.Eval (Container.DataItem,"voucherid") is nothing,True,false) %>' runat="server" Text="<a href=http://www.microsoft.com>Update</a>" 
 
and it work.

Hello Lui Nai Wah,

Try the following code instead:

<asp:Label ID="LinkButton1" runat="server"
    Visible='<%# IIf(DataBinder.Eval(Container.DataItem, "voucherID") is Nothing, "true", "false")%>'>
     <a href="#" onclick="openRadWindow2('<%#DataBinder.Eval(Container.DataItem,"voucherID")%>'); return false;">Update</a>
</asp:Label>

Let us know if any issues arise.

hi

still it didn't work.

I am wondering surely someone has posted similar requirement while using radwindow.

It cannot be that while i am required to use radwindows with javascripts and yet i am not able to hide or disable it based on certain conditions. Strange?

I am frustrated...

Help me if you can. Thanks a million.
