 How to have Whole DataGrid in Editmode

I found a solution for editable columns!!!

I have controls in my app with editable columns that I designed this

It's not the cleanest code but it works.

Here's the code that the page.onsubmit implements that gets the values of a
column of Textboxes .

I have a table loaded into a grid, and the ItemTemplate of one of the
columns is a text box.  When the page is submitted I go through the grids
items, which is equal to the number of rows in the table it's representing
and do a findcontrol on the textbox's name "ParentId" in this case and then
get the unique name from it's naming container which allows me to get it's
value from the request parameters returned from the page..

private void Submit1_ServerClick(object sender, System.EventArgs e)


                  //  I saved the dataset that was loaded into the grid in a
session variable.

                  DataSet ds = (DataSet)Session["handofflist"];

                  int nRecords = ds.Tables[0].Rows.Count;

                  int cd = DataGrid1.Items.Count;

                  for (int c = 0; c < DataGrid1.Items.Count;   c++)


                        Control ParentIdTextBox =

                        if (ParentIdTextBox != null)


                              string viewStateData =
Request.Params.Get(ParentIdTextBox.NamingContainer.UniqueID + ":ParentId");

//((DataColumn)ds.Tables[0].Rows[c]["NEW_PARENT_CONTAINER_ID"]).ReadOnly =

ds.Tables[0].Rows[c]["NEW_PARENT_CONTAINER_ID"] = viewStateData;

                              DataRow r = ds.Tables[0].Rows[c];

                              DataRow r2 = ds.Tables[0].Rows[c];



                  DataColumn[] keys = new DataColumn[2];

                  keys[0] = ds.Tables[0].Columns["container_id"];

                  keys[1] = ds.Tables[0].Columns["transfer_id"];

                  ds.Tables[0].PrimaryKey = keys;

                  int count = UpdateAdapter.Update(ds.Tables[0]);

                  DataGrid1.DataSource = ds;
