I have a page that when I first load the page, I want to show a grid that has student information on it.  When the user selects Teacher from the dropdown box, I want the student grid to disappear and the Teacher grid that has totally different information and headers to appear.

I also want to enable paging on this page. 
My problem is the "NeedDataSource" for both grids.  It doesnt work for the teacher.

Hi Mike,

When changing the grid visibility please call Rebind().

Hello Mike,

You can change the DataSource on the SelectedIndexChanged property of the DropDownList. Check out the following code.
aspx:
  <asp:DropDownList ID="DropDownList1" AutoPostBack="true" runat="server" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"
         <asp:ListItem Text="student">         
        </asp:ListItem> 
        <asp:ListItem Text="teacher">         
        </asp:ListItem>            
        </asp:DropDownList> 
      
        <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" > 
            <MasterTableView DataSourceID="SqlDataSource1">               
            </MasterTableView> 
        </telerik:RadGrid> 
      
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyDataBaseConnectionString %>" 
            SelectCommand="SELECT * FROM [Projects]"></asp:SqlDataSource> 
       
       <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:MyDataBaseConnectionString %>" 
           SelectCommand="SELECT * FROM [Reservation]"></asp:SqlDataSource> 

cs:
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) 
    { 
        if (DropDownList1.Text == "teacher") 
        { 
            RadGrid1.DataSourceID = "SqlDataSource2"
        } 
        else 
        { 
            RadGrid1.DataSourceID = "SqlDataSource1"
        }         
    } 

Princy.

The Teacher and Student Grids have different columns.
They are both templated, not create on the fly.

Changing just the datasource wont work, will it?
