Default Editing Datagrid

Hi Everyone,
I have brought in a table from SQL Server into ASP.NET through Datagrid and have turned all fields into textboxes so the user can edit any textbox and click save once. However when the save button is clicked then all textboxes are changed to the value which is in the last row. Here is the code for my save button:

Private Sub doSave(ByVal sender As Object, ByVal e As System.EventArgs)

Dim myCommand As SqlCommand
Dim dstCopy As New DataSet
Dim strQuery As String

objConnection = New SqlConnection("server=SQLSERVER;database=upsizedCa ndidate;Integrated Security=True;")
objConnection.Open()

Dim dgItem As DataGridItem
For Each dgItem In myInfo.Items
Dim txtNewColumn1 As TextBox = CType(dgItem.Cells(0).FindControl("txtNewCol1"), TextBox)

Dim txtNewColumn2 As TextBox = CType(dgItem.Cells(1).FindControl("txtNewCol2"), TextBox)

strQuery = String.Format("update ToddsTable3 set NewCol1= '" + txtNewColumn1.Text + "',NewCol2='" + txtNewColumn2.Text + "'")

myCommand = New SqlCommand(strQuery, objConnection)
myCommand.ExecuteNonQuery()

Next

DataBind()
myInfo.DataBind()
objConnection.Close()
myInfo.EditItemIndex = -1


BindGrid()
End Sub

I have no idea what could be wrong and this has been driving me crazy. could anyone please help me? Thanks in advance

hi there... first of all your update doesn't have any where clause.. so it's updating all the table!

maybe there is a problem with the data you are obtaining??

also the grid has this functionality built in.. so you don't have to write any code to do this..

Hi again, sorry to bother you but I have just one more bug that I cannot figure out. When I click save, it gives me the following error:
Exception Details: System.Data.SqlClient.SqlException: Invalid column name '__Page'.

The debug says it is occurring at the line:
myCommand.ExecuteNonQuery()


I've checked everywhere and nothing resembles "Page". any thoughts?

Hi Gonzalo,
     I switched all instances of ID to resemble the other two columns and it worked perfectly. Thanks for helping me! You've made my weekend!
