I have a dropdown list that bind my data into my gridview. Everything works fine except that when changing my selected data from my dropdown I noticed that the new loaded data in my gridview was on the same page that was when you were in the previous data, How to bring it up to the first page when a new selected data from the dropdown.
For instance, if you're on the 3rd page of the in the list and switch to new data from the dropdown you will start out on page 3, not the first page of the list
Thanks in advance for the help...

All columns, visible or invisible are accessed in the same way programmatically. The invisible columns are just hidden from the design and runtime view, but still exist in the object.

Hi all,
My apologies if this is an easy one (v.new to this!) but I get the following error when clicking edit a datagrid with a dropdownlist.
'System.IndexOutOfRangeException: StatusID'
In my datagrid I'm calling functions in VB. One to get the status and populate a Dataset & one to get selected index so I can set the initial value of the dropdownlist.
I then have the update sub to declare the dropdownlist and and update the database.
Would anyone be able to point me in the right direction?
Many Thanks
Rob

Is status ID a valid identifier for the drop down list's selected index property?
Do you really want the selected rows index?
If possible could you post the code so I can see what you are doing please?

Hi Dan, thanks for the reply.
Here is my code showing functions to populate the dataset and to get the selected row.
StatusID is the primary key in my access database & thought I'd need to use it to default the value of the dropdownlist to the current value.
Function GetStatus() as DataSet
Dim DBConn as OleDbConnection
Dim DBCommand as OleDbDataAdapter
DBConn = New OleDbConnection("PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=" & Server.MapPath("data/Auto_log.mdb") & ";")
DBCommand = New OleDbDataAdapter("SELECT StatusID, Status from Status ORDER BY Status", DBConn)
DBCommand.Fill(DS, "Status")
DBConn.Close()
Return DS
End Function
Function GetSelectedIndex(ByVal StatusID As String) As Integer
'Loop through the DataSet DS
Dim iLoop As Integer
Dim DT As DataTable = DS.Tables("Status")
For iLoop = 0 To DT.Rows.Count - 1
If StatusID = DT.Rows(iLoop)("StatusID").ToString Then
Return iLoop
End If
Next iLoop
End Function
I then declare the ddl in my update subroutine as follows
Dim ddlStatus As DropDownList = FindControl("ddlStatusctrl")
and here is the ddl control from my datagrid:
<asp:TemplateColumn>
<HeaderTemplate>
Status
</HeaderTemplate>
<ItemTemplate>
<%# Container.DataItem("Status") %>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList id="ddlStatusctrl" runat="server"
DataTextField="Status"
DataValueField="StatusID"
DataSource="<%# GetStatus() %>"
SelectedIndex='<%# GetSelectedIndex(Container.DataItem("StatusID")) %>' />
</EditItemTemplate>
</asp:TemplateColumn>

You can try this with Session. If the Browser closes the close button it will get deleted.

When user closes the browwer window the onunload event fires of the body element. Use a function to handle the event raised and in the function send an asynchronous request to the browser using XMLHTTP object and delete the data from the database.
