Hello <insert name here>,
It seems like you're doing something the hard way. All you need is a
reference to the selected row and from that you can use FindControl to
locate the ddl. With that you pull out the value. Below, I've inserted a
working sample that might get you going. Let us know if it helps?

Hi there,
please help if you can, I'm having an issue with droponnlists in a
datagrid
I have a datagrid which is populated from a query .. all works fine
I've added two extra columns, one is a dropdownlist and the other is a
button which runs the command selectcode for this:
<Columns>
<asp:BoundColum n DataField="Salu tation"
HeaderText="Sal utation"></asp:BoundColumn >
<asp:BoundColum n DataField="Firs tName" HeaderText="Fir st
Name"></asp:BoundColumn >
<asp:BoundColum n DataField="Last Name" HeaderText="Las t
Name"></asp:BoundColumn >
<asp:BoundColum n DataField="Post Code" SortExpression= "Post Code"
HeaderText="Pos t Code"></asp:BoundColumn >
<asp:TemplateCo lumn HeaderText="Use rs">
<ItemTemplate >
<asp:DropDownLi st id=DDlUsers runat="server" DataSource="<%#
Itemtypes %>" >
</asp:DropDownLis t>
</ItemTemplate>
</asp:TemplateCol umn>
<asp:ButtonColu mn Text="Select" ButtonType="Pus hButton"
CommandName="Se lect"></asp:ButtonColum n>
</Columns>
The datagrid renders correctly and when I click the button I've written
code to find the id of the dropdownlist on the same row as the button
which has been clicked ... however I can't access the dropdownlist value
and I NEED to do this in order to continue with my project.
My code is listed below:
Private Sub LeadsDG_Selecte dIndexChanged(B yVal sender As Object, ByVal e
As System.EventArg s) Handles LeadsDG.Selecte dIndexChanged
Dim ddstr As String
ddstr = LeadsDG.Selecte dItem.Cells(4). Controls(0).Cli entID
ddstr = Replace(ddstr, "__ctl1", "_DDlUsers" )
End Sub
Please someone tell me how to access the drop down, I've tried this
(with writing the vlue to a text box):
Dim DDlist1 As DropDownList = CType(LeadsDG.F indControl(ddst r),
DropDownList)
TextBox1.Text = DDlist1.Selecte dItem.Value
But I get the following error when I click a value:
Object reference not set to an instance of an object.
Please help me access the dropdownlist values, I know that the sub is
being run and that the id is the correct control, but I'm stuck getting
it working
Regrds,
m3ckon
