How to remove a column from GridView

Hi Friends,  I have a DataTable with 2 columns (ID,  SomeData) that is I am getting from my DataBase, now I want to show in the gridview only two columns (Name, SomeData), Name I am getting from some web service, code is something like this.

  Datatable dt;
  dt = getMyTable();
  dt.Columns.Add("Name", typeof(string));
  myGridView.DataSource = dt;

  e.row.cells["Name"].Text = myWebService.getEmployeeName(Convert.Int32(e.Row.Cell["ID"].Text)               
  e.row.cells["SomeData"].Text = “<a href=’MoreDetails.aspx?ID=” + e.Row.Cell["ID"].text + ”’>” + e.Row.Cell["SomeData"].Text + “</a>”;

Problem is I want to show ID column. I can’t remove the ID column from datatable before databinding (coz I need that column for anchor tag on SomeData column). And I am getting exception if i try to set that columns visible property to false after binding (column dosnt exist) . Please suggest.Thank you in advance.

Don't bind the ID column with the grid.

Use the grid property DataKeyNames="ID" in <asp:GridView........... />

Visit Gridview Hidden Column for the usage 

Hope that helps Yes

thanks for reply, but I can't use TemplateField i didnt' mention one thing that is my second column is dynamic mean some times i get my table like this (ID, SomeData1) next time may be table like this (ID, SomeData1, SomeData2) next time (ID, SomeData1, SomeData2, SomeData3) so the problem is my number of columns are dynamic based on the selected option of user.

i was not able to hide column so i hide the cell, at the time of RowDataBound

  e.row.cells["Name"].Text = myWebService.getEmployeeName(Convert.Int32(e.Row.Cell["ID"].Text)               
  e.row.cells["SomeData"].Text = “<a href=’MoreDetails.aspx?ID=” + e.Row.Cell["ID"].text + ”’>” + e.Row.Cell["SomeData"].Text + “</a>”;
  e.row.cells["ID"].visible = false;

remove a gridview column dynamically, removes controls in template columns
I have a interface with a treeview and a gridview. The gridview has two templatefields that handles insert/update/deletes. The gridview is handling editing of different tables so I create the other columns in the gridview dynamically as boundfields. The user selects the table to edit in the treeview. The problem I am having happens when the user selects a table to edit the second time. The code that executes removes all bound fields, (dynamically added when user selected the first table in the treeview), but not the two template fields, and then adds boundfields specifi...

Gridview control removing consecutive spaces in column output
 Hi, i am using a simple GridView to retrieve data from a SQL view, and if there are consecutive spaces in the string in a particular column, something (asp?) is removing the 2nd space, and then the output has only 1 space, which is incorrect for this string. Interestingly, if I retrieve the same column with a specific select statement in a code behind file, and then output it via either response.write, or in a text box, it does the same thing.   I have debugged while doing this and in the Autos window, the string is correct (with two consecutive spaces), then when it is ...
