Verify that you have everything wired up properly and are assigning a DataSource and doing a DataBind(). Once you have verified that these two things are happening then make sure that your DataSource is returning some type of result set with at least one item.

A GridView will not display anything at all unless there is at least 1 item in the result set. If you bind to a DataSet or some type of object list and there are not items in it then the grid will no display at all. Not even the headers. In this case you should setup the EmptyDataText property to display something.

If not if this helps, please post your GridView markup and the code where you bind your grid and I'll see if I can figure out what the issue is.

check aspx page code

<asp:MyGridView runat="server" DataKeyNames="pkey" AutoUpdateAfterCallBack="true"
            Width="100%"
            ID="grduser" AutoGenerateColumns="False">
            <Columns>
                <asp:BoundField HeaderText="Sr No." DataField="rownumber" ReadOnly="true" HeaderStyle-Width="10px"
                    ItemStyle-Width="10px" />

                <asp:BoundField HeaderText="FirstName" DataField="FirstName" SortExpression="FirstName"
                    ReadOnly="true" HeaderStyle-Width="120px" ItemStyle-Width="120px" />
                <asp:BoundField HeaderText="LoginName" DataField="LoginName" SortExpression="LoginName"
                    ReadOnly="true" HeaderStyle-Width="120px" ItemStyle-Width="120px" />
                <asp:BoundField HeaderText="Email" DataField="Email" SortExpression="Email" ReadOnly="true"
                    HeaderStyle-Width="120px" ItemStyle-Width="120px" />
                <asp:BoundField HeaderText="Role" DataField="Role" SortExpression="Role" ReadOnly="true"
                    HeaderStyle-Width="30px" ItemStyle-Width="30px" />
                <asp:BoundField HeaderText="Reportingto" DataField="Reportingto" SortExpression="Reportingto"
                    ReadOnly="true" HeaderStyle-Width="120px" ItemStyle-Width="120px" />
                <asp:BoundField HeaderText="MobileNo" DataField="MobileNo" SortExpression="Mobile_no"
                    ReadOnly="true" HeaderStyle-Width="30px" ItemStyle-Width="30px" />

            </Columns>
        </asp:MyGridView>

Cs file code to bind grid

DataSet ds = new DataSet();
ds = //get dataset form the database 
DataView dv = new DataView(ds.Tables[0]);
this.grduser.DataSource = dv;
this.grdusers.DataBind();

Easiest way is as Kelsey says:

<emptydatatemplate>              
   No Data Found. 
</emptydatatemplate> 

Other techniques:

1) Override the CreateChildControls (example: http://forums.asp.net/t/1003306.aspx)

2) Manually insert a row (example: http://geekswithblogs.net/dotNETvinz/archive/2009/03/11/tiptrick-show-header-and-footer-of-gridview-when-no-data.aspx)
