Hi There,

I want to call a server method from gridview's template field, but it
doesn't seem to be working, any idea what is wrong in this.


Thanks

<ItemTemplate>

<asp:Image BorderWidth=1 Height=16 Width=16 ID="Image1" runat="server"
ImageUrl='<%# Eval("City") %>' />

<asp:TextBox Text ='<%# Eval("City") %>' runat="server" />

<asp:TextBox ID="TextBox134" Text ='<%# CallTest(<%# Eval("City") %>) %>'

You are using databind expressions. How do you databind?

Your function will be called during databinding. How do you databind? Do you
set DataSourceID property? Or call DataBind() method? If you do one of them,
it should work. If you do none, it won't.

That's a databinding expression - how are you doing the databinding...?

Hi

I don't do any data binding, i use asp.net 2.0, when i setup gridview then
assign datasource design time with some query receives some session
variable. when page load automatically it gets data binded.

I try to call a function like this
http://msconline.maconstate.edu/tutorials/ASPNET2/ASPNET07/aspnet07-05.aspx
this is in Binding functions to a GridView listing 7-12. i'm wondering why
it's not working for me.

Thanks
