Binding a DropDownList inside a DetailsView
- by annelie
Hello,
I'm having problems trying to populate a dropdownlist from the database. When I'm trying to set the datasource I can't find the dropdown control, it's in a DetailsView so I think it might have something to do with it only being created when it's in edit mode. It still says it's in current mode when I'm editing though, so not sure what's going on there.
Here's the code from the aspx file:
<asp:DetailsView id="DetailsView1" runat="server" AutoGenerateRows="false" DataSourceID="myMySqlDataSrc" DataKeyNames="id" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" AutoGenerateInsertButton="False" >
<Fields>
<snip>
<asp:TemplateField HeaderText="Region">
<ItemTemplate><%# Eval("region_name") %></ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="RegionDropdownList" runat="server" SelectedValue='<%# Bind("region_id")%>'>
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
</Fields>
</asp:DetailsView>
And this is from the code behind:
ArrayList regionsList = BPBusiness.getRegions();
if (DetailsView1.CurrentMode == DetailsViewMode.Edit)
{
DropDownList ddlRegions = (DropDownList)DetailsView1.FindControl("RegionDropdownList");
if (ddlRegions != null)
{
ddlRegions.DataSource = regionsList;
ddlRegions.DataBind();
}
}
It's .net 2.0 if that helps.
Thanks,
Annelie
