Bhushan Posted March 17, 2006 Author Share Posted March 17, 2006 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 Link to comment Share on other sites More sharing options...
aspnetguy Posted March 17, 2006 Share Posted March 17, 2006 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. Link to comment Share on other sites More sharing options...
