Forms Data Controls :: Dropdown Doesn't Load With The Relevant Data When Select A Value From The First
Jun 10, 2010I am experimenting with 3 dropdowns bound to 3 different datasources. I want the contents in each dropdown depending on what is selected from the above dropdown and the datasource queries reflect this.

Width="138px" DataSourceID="CostCentreDataSource" DataTextField="CostCentre"
DataValueField="CostCentreID">

SelectCommand="SELECT [CostCentreID], [CostCentre] FROM [CostCentres]">
</asp:SqlDataSource>

<asp:Label ID="Label2" runat="server" Text="Manager:" Font-Bold="True"></asp:Label>
<br />
<asp:DropDownList ID="DropDownList_Managers" runat="server" Height="16px"
Width="138px" DataSourceID="ManagerDataSource" DataTextField="EmployeeName"
DataValueField="EmployeeID">
</asp:DropDownList>
<asp:SqlDataSource ID="ManagerDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [EmployeeID], [EmployeeName] FROM [Employees] WHERE ([CostCentre] = @CostCentre)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList_CostCentres" Name="CostCentre"

However, the second dropdown does not load with the relevant data when I select a value from the first dropdown (stays blank). Must I still provide an event handler and how do I combine this with the sqldatasource?

View 1 RepliesForms Data Controls :: Use Dropdown List With Objectdatasource
Aug 13, 2010I will try to keep the question short:
1. I am new to ASP and I can not get this to work:
2. I am Using a <asp:DropDownList in a <InsertItemTemplate> in a <asp:ListView
3. The dropdownlist during insert does not get polulated (it is empty) while the same construction and same datasource works in the edittemplate: <asp:DropDownList in a <EditTemplate> in a <asp:ListView
4. I noticed that filling the dropdownlist with a <asp:ListItem works; the insert list is populated. (not usable for me) In both cases I use the same datasource from the code behind like this : Edit:
<asp:DropDownList ID="DropDownStartday" runat="server" SelectedValue='<%# Bind("startday") %>'
DataSource="<%# GetDataSourceStartDay() %>" DataValueField="daynum" DataTextField="dayname"
Insert: (with or without Selectedvalue: NoJoy)
