Are you getting an erro or just nothing??You forgot to add a (.)

TextBox t=(TextBox).DetailsGrid.FindControl("txtName");

Hi,When I add (.) it gave me error saying TextBox defines a class where a variable is expected. In the first place, do I have to include anything else??.I have hierarchy like this.I am facing a problem in my project where in I have made use of a Data Grid and inside it I have used a HTML table and inside <td> I am using a asp TextBox.When I tried to find out this TextBox using string str=((TextBox)e.Item.Cells[0].FindControl("txtName")).Text;Response.Write(str);It is giving me an error saying “bject reference not set to an instance of an Object”Please suggest me how can I resolve this??. I am also mailing you the piece of code which might be useful for you to pin point my mistake !. I tried here something different. But even this didn't work out. ASPX code: I have the following textbox under <table> which is inside a DataGrid. <td><asp:TextBox ID="txtName" Runat="server" ReadOnly=True Text='<%#DataBinder.Eval(Container.DataItem,"ResourceName")%>'></asp:TextBox></td> <FooterTemplate><asp:Button ID="btnEdit" Runat="server" Text="EDIT" CommandName="edit_here" /></FooterTemplate> I have a ItemCommand=”mCommandHandler” as my DataGrid property. CodeBehind: public void mCommandHandler(object sender,DataGridCommandEventArgs e) { if(e.CommandName=="edit_here") { TextBox t=(TextBox)e.Item.FindControl("txtName"); string str=t.Text; Response.Write(str); } } Please help me in getting rid of this problem.Thanks in advance,Bhushan

why not just use

Page.FindControl("txtName");

If it exists on the page it will be found. That way you don't have to worry about searching the correct celss, etc.
