try to look for
this.GridView1  (in C#)
or
Me.GridView1 (in VB.net)
using intellisense in the Codebehind
You may be providing a vriablename with wrong case

Yes - i searched all open files - including code behind.

Ok - i ran the program it ran but gave me an error page - i viewed the source and found this...

private global::System.Web.UI.WebControls.GridView @__BuildControlGridView1() {
Line 426:              global::System.Web.UI.WebControls.GridView @__ctrl;
Line 427:              
Line 428:              #line 50 "C:\svn\webservice\Default.aspx"
Line 429:              @__ctrl = new global::System.Web.UI.WebControls.GridView();
Line 430:              
Line 431:              #line default
Line 432:              #line hidden
Line 433:              this.GridView1 = @__ctrl;
Line 434:              @__ctrl.ApplyStyleSheetSkin(this);
Line 435:              
Line 436:              #line 50 "C:\svn\webservice\Default.aspx"
Line 437:              @__ctrl.ID = "GridView1";



I have tried deleting gridview1 and adding a new one...

I havent tried it like that. My data source is an array list - this is what i'm doing...I dont think i can add that as a data source in design view.

ArrayList eventArrayList= ArrayList.Adapter(eventArray);
Gridview1.Datasource = eventArrayList;
Gridview1.Databind();

Hi,
can you check the following discussion
http://forums.asp.net/thread/1336317.aspx

are you using Visual Web developer or Visdual Studio. If possible can you paste the sources of  .aspx and the code behind files. So that we can check it and provide a solution.

Kind regards

this is strange, I copy pasted your code to a new webform and when I built the solution I got the same error message. I then tried accessing GridView1 using the this keyword like
this.Gridview1.Datasource = eventArrayList;
this.Gridview1.Databind();

and when I built the project again it worked without any errors. Added to this now when I remove the this keyword and built the project it worked again.
Something strange is happening in VS.Net
can you try it and see whether it works for you also

Kind regards
Venki
