I am creating custom Gridview for dynamic Columns (getting columns from Database) and addting textboxes to headers for filtering data. I set the "EnableViewstate=False".
My problem is when I click on Filter Button it is not firing RowCommand event.
here is my code.

I have one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:

i have a repeater with a button in the footer template which i want to be able to update any of the items that are added (update quantites/totals/delete the item).
however the 'UpdateOrderDetails' event never fires when the button is clicked.
here is the code within the repeater...
<ItemTemplate>
<tr>
<td>
<asp:CheckBox ID="chkDelete" runat="server" />
<asp:HiddenField ID="hidProduct_Key" runat="server" />
[Code].....
but this procedure is never called when the button is clicked, so wondered what i need to do to get this working
I have a repeater control and in its footer temlate is a button (or 2 in the example) and I want to catch its click event but seem to not be able to.
I tried in the repeater itemcommand event and also I tried defining a subprocedure for the 'occlick' event but neither works..

I have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense
Code creating columns
Dim gvTownships As New GridView
'COLUMNS
Dim tmpCategory As New TemplateField
tmpCategory.ItemTemplate = New cGridViewTemplate(DataControlRowType.DataRow, "Category")
tmpCategory.HeaderTemplate = New cGridViewTemplate(DataControlRowType.Header, "Category")
tmpCategory.FooterTemplate = New cGridViewTemplate(DataControlRowType.Footer, "Calculation")
'INFORMATION
gvTownships.AutoGenerateColumns = False
gvTownships.ID = cmbChoice.SelectedItem.Text
gvTownships.ShowFooter = True
gvTownships.CssClass = "mGrid"
gvTownships.RowStyle.Wrap = False
gvTownships.HeaderStyle.CssClass = "mgrid"
gvTownships.HeaderStyle.Wrap = True
gvTownships.FooterStyle.CssClass = "mGridtf"
gvTownships.AlternatingRowStyle.CssClass = "alt"
gvTownships.GridLines = GridLines.Both
'add columns
gvTownships.Columns.Add(tmpCategory)
gvTownships.DataSource = dstSuburbTowhShip
gvTownships.DataBind()
Code to add button to footer
Sub InstantiateIn(ByVal container As System.Web.UI.Control) _
Implements ITemplate.InstantiateIn
Case DataControlRowType.Footer
If columnName = "Calculation" Then
Dim btnCalculate As New Button
btnCalculate.Text = "Calculate"
btnCalculate.CssClass = "button"
'add handler
AddHandler btnCalculate.Click, AddressOf btnCalculate_Clicked
container.Controls.Add(btnCalculate)
End If
Case Else
' Insert code to handle unexpected values.
End Select
End Sub
Private Sub btnCalculate_Clicked(ByVal sender As Object, ByVal e As EventArgs)
Try
Dim btnCalculate As Button = CType(sender, Button)
Dim gvRow As GridViewRow = CType(btnCalculate.NamingContainer, GridViewRow)
btnCalculate.CommandArgument = "Calculate"
Catch ex As Exception
End Try
End Sub

I have used the above grid view in my application ... Its working good, no problem.
Upon clicking the Addnewrowbutton, it uses to create a new row dynamically.
What i need is, new row should also be created dynamically, upon pressing enter key in the last textbox on a particular gird view row. User always can't go and click addnewrowbutton every time to create new row. Instead of it, user can press enter in the last textbox on a particular grid view row to create new row.

I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
I have write the code in .Net. When I click the Buttun then fired below event.

I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box
