Good Morning,
Quick question, I have an EditItemTemplat e inside a datagrid. It should
contain a drop down list of possible choices. I have an EditCommandColu mn.
The drop dow list column should initially contain the value of the field.
This works fine with
<ItemTemplate>< %# Container.DataI tem("NameType") %></ItemTemplate>
The desired effect is for the drop down list to databind to a query to show
possible choices when the user clicks the edit link. I can not get a
reference to the drop down list when the user clicks edit. Does anyone know
how to do this?
I tried page.findcontro l("controlname" ) and it does not work. Any ideas? I
get a NullReference Error when I do this, because I guess the control does
not exist on the page.
Thanks to everyone,
Chris 4 1467
Within the method that handles the datagrid EditCommand event you can get a
reference to the dropdown list by using the passed DataGridCommand EventArgs
as follows:
CType(e.Item.Fi ndControl("cont rolname"), DropDownList)

No, that still didn't work. Any other suggestions?
I ended up with this
Sub DataGrid_Edit(B yVal Sender As Object, ByVal E As
DataGridCommand EventArgs)
' turn on editing for the selected row
Dim ddl As DropDownList = CType(E.Item.Fi ndControl("drpN ameType"),
DropDownList)
If Not isEdit Then
dg1.EditItemInd ex = E.Item.ItemInde x
BindGrid()
End If
End Sub
Using a breakpoint, I see ddl = Nothing. What am I doing wrong here? Thanks!

e.items.findcon trol("controlna me")

Even tough I was able to implement what I want in a weird and non efficient

Scenario:
• Display a DataGrid that contains rows from a table from a databse (so far
easy).
• I would like to add a column to the DataGrid that will be a drop-down list
so the user will be able to select a value from a pre-defined list of values
