set selected value declaratively to dropdownlist

[podi]

Hi,
I just wonder if there is a way to set a selected item in dropdown list
which items are retreived from database without touching c# code ?

I mean, i have in gridview, in edit mode one dropdownlist which
selected value should be the same as a label text from normal view mode

<EditItemTemplate>
<aspropDownList ID="ddlGrdvFrequency" runat="server"
DataTextField="Frequency"
DataValueField="FrequencyId"
DataSourceID="SqlDataSourceMembershipFrequency" />

</EditItemTemplate>

I was looking for sth like SelectedIndex, but intellisense did not give
me any prompt for it. I use now C# code in databound event for gridview
to set this item selected, but ...is there a way of not using this ?
thanks for any prompts

Hi,
You can set the selectedvalue property on the dropdownlist as follows
<EditItemTemplate>
<aspropDownList runat="server" ID="ddl"
DataSourceID="SqlDataSource2"
DataValueField="ProductID"
DataTextField="ProductName" SelectedValue='<%# Bind("ProductID")
%>'></aspropDownList>
</EditItemTemplate>

hi podi,
unfortunately the SelectedIndex cannot be set declaratively, it is a compile
error. i'm just wondering how you could know in advance with a databound
list which one to select?
an alternative would be to sort the datasource so that the one you want to
select is the first record, then it will be selected by default when the
list is databound.

i think the databound event is the correct (and best) place to achieve your
task.
i hope this helps
