Question

I am working on asp.net gridview (WEB.UI.Contorl).
I want to use one gridview only. When a button is clicked,
gridview1 should be filled by table1.
When second button is clicked,
gridview1 should be filled by table2.

Is this possible..?

Have you tried this

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" 
        Text="Button 1" />
    <asp:Button ID="Button2" runat="server" onclick="Button2_Click" 
        Text="Button 2" />
    <br />
    <asp:GridView ID="GridView1" runat="server">
    </asp:GridView>

in code behind

protected void Button1_Click(object sender, EventArgs e)
    {
        GridView1.DataSource = CallToMethodThatReturnFirstDatatable();
        GridView1.DataBind();
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
        GridView1.DataSource = CallToMethodThatReturnSecondDatatable();
        GridView1.DataBind();
    }
