Проблема заключалась в том, что мой метод RowCommand вызывал DataBind
Неправильный путь:
Protected Sub GridView2_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles GridView2.RowCommand
If e.CommandName = "NewDataInsert" Then
Dim refNo As TextBox = GridView2.Controls(0).Controls(0).FindControl("NewRefNo")
Dim resource As TextBox = GridView2.Controls(0).Controls(0).FindControl("NewResource")
Dim hours As TextBox = GridView2.Controls(0).Controls(0).FindControl("NewHours")
Dim offset As TextBox = GridView2.Controls(0).Controls(0).FindControl("NewOffset")
Dim newResAlloc As DataTable = resourceInfo.loadResAllocations
Dim newAllocRow As DataRow = newResAlloc.NewRow
newAllocRow.ItemArray = New Object() {Nothing, refNo.Text, resource.Text, hours.Text, offset.Text}
newResAlloc.Rows.Add(newAllocRow)
resourceInfo.updateResAllocations(newResAlloc)
ElseIf e.CommandName = "InsertNew" Then
Dim refNo As TextBox = GridView2.FooterRow.FindControl("InsertRefNo")
Dim resource As TextBox = GridView2.FooterRow.FindControl("InsertResource")
Dim hours As TextBox = GridView2.FooterRow.FindControl("InsertHours")
Dim offset As TextBox = GridView2.FooterRow.FindControl("InsertOffset")
Dim newResAlloc As DataTable = resourceInfo.loadResAllocations
Dim newAllocRow As DataRow = newResAlloc.NewRow
newAllocRow.ItemArray = New Object() {Nothing, refNo.Text, resource.Text, hours.Text, offset.Text}
newResAlloc.Rows.Add(newAllocRow)
resourceInfo.updateResAllocations(newResAlloc)
End If
GridView2_DataBind() 'Culprit
End Sub
