I have an itemtemplate in a datagrid. I'm trying to set it's value based on
data. Having no trouble with the textbox. But, how do I do the same thing
for a dropdownlist????
<ItemTemplate>
<asp:DropDownList id="ddlYesNo" runat="server" >
<asp:ListItem Value="-">-</asp:ListItem>
<asp:ListItem Value="Yes">Yes</asp:ListItem>
<asp:ListItem Value="No">No</asp:ListItem>
</asp:DropDownList>
<asp:TextBox id="txtComments" runat="server" Width="168px"
Text='<%# DataBinder.Eval(Container.DataItem, "Comments") %>'></asp:TextBox>
</ItemTemplate>
As you can see the TextBox works great! But, how do I set the
DropDownList's value to a similar data field?
Thanks! 6  1749 
You can either go in the ItemDataBound event and do
dim ddl as dropdownlist = ctype(e.item.findControl("ddlYesNo"),
dropdownlist)
ddl.selectedIndex = 1
or you can do something like
<asp:listItem value="yes" selected='<%# DataBinder.Eval(Container.DataItem,
"yesNo") = "yes"%>'>
<asp:listItem value="yes" selected='<%# DataBinder.Eval(Container.DataItem,
"yesNo") = "no"%>'>
or something like that.

Oh well, I was wrong.
You'll need to do it the other way:
Private Sub x_ItenDataBound(ByVal source As Object, ByVal e As
RepeaterItemEventArgs) Handles x.ItemDataBound
'get a reference to the DLL here and via e.Item.FindControl("ddlYesNo")
and you can access the row via e.Item.DataIem which will allow you to apply
the logic you need to figure out which item to select
End Sub

As I said, you have access to e.Item.DataItem. which is an object, but can
be cast to a DataRowView (assuming you are binding form a
datatable/dataset/dataview)
dim dv as DataRowView = ctype(e.item.DataItem, DataRowView)
if cstr(dv("yesNo")) = "yes" then
...
I think it's a datarowview anyways...
