Hi
Hi i have

VB

<asp:GridView ID="GridView1" 
                        runat="server"  ><column></column></GridView

If i use the control means

GridView gd = (GridView)this.Page.FindControl("GridView1");
gd.datasource=dt;

It shows the error "Object reference not set to an instance of an object."

Any suggestions please...............

Firstly, the syntax inside the gridview should be <columns>.
Secondly, you could access the gridview just by calling his ID in code-behind ...
What do you have in your designer file ?

Just use its name directly:

GridView1.datasource=dt;

Syntax error : end tag is not matching

try this

XML

<asp:GridView ID="GridView1" runat="server">
            <Columns></Columns>
        </asp:GridView>

C#

GridView GridView1 = this.FindControl("GridView1") as GridView;
