I have to rad combo boxes, RadLaborSchedule (rad1) and RadLaborCatDesc (rad2). Both these rad combo boxes are declared as EditItems in a radgrid. How do I populate rad2 with selected value of rad1?

I tried using this code in javascript, which errors out at compile time because RadLaborCatDesc can not be found, being an edit item of a rad grid.

Thanks.

Here is the javascript:

//global variables for the countries and cities comboboxes

var LaborCatCombo;

function pageLoad()

{

// initialize the global variables

// in this event all client objects

// are already created and initialized

LaborCatCombo = $find(

"<%= RadComboBoxLaborCatDesc.ClientID %>");

}

function LoadLaborCategories(combo, eventArqs)

{

var item = eventArqs.get_item();

LaborCatCombo.set_text(

"Loading...");

LaborCatCombo.clearSelection();

// if a labor schedule is selected

if (item.get_index() > 0)

{

// this will fire the ItemsRequested event of the

// countries combobox passing the continentID as a parameter

LaborCatCombo.requestItems(item.get_value(),

false);

}

else

{

// the -Select a continent- item was chosen

LaborCatCombo.set_text(

" ");

LaborCatCombo.clearItems();

}

}

And this is the radgrid declaration:

<telerik:GridTemplateColumn DataField="LaborSchedule" HeaderText="Labor Schedule" UniqueName="LaborSchedule">

<asp:Label id="LabelLaborSchedule" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "LaborSchedule")%>'

></asp:Label>

</ItemTemplate>

<telerik:RadComboBox DataTextField="LaborSchedule"

DataValueField="LaborSchedule"

AutoPostBack="false"

EnableLoadOnDemand="True"

ID="RadComboBoxLaborschedule"

runat="server"

Height="140px"

Width="100px"

SelectedValue = '<%#DataBinder.Eval(Container.DataItem, "LaborSchedule")%>'

SelectedText = '<%#DataBinder.Eval(Container.DataItem, "LaborSchedule")%>'

DataSourceId = "ObjectDataSourceGetSchedules"

OnItemsRequested= "RadComboBoxLaborschedule_ItemsRequested"

OnClientSelectedIndexChanging="LoadLaborCategories"

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="LaborCategoryDesc" HeaderText="LaborCategoryDesc" UniqueName="RadComboBoxLaborCatDesc">

<asp:Label id="LabelLaborCategoryDesc" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "LaborCategoryDesc")%>'

></asp:Label>

</ItemTemplate>

<telerik:RadComboBox ID="RadComboBoxLaborCatDesc" runat="server"

DataTextField="LaborCategoryDesc"

DataValueField="LaborCategoryCode"

SelectedValue = '<%#DataBinder.Eval(Container.DataItem, "LaborCategoryCode")%>'

SelectedText = '<%#DataBinder.Eval(Container.DataItem, "LaborCategoryDesc")%>'

DataSourceId = "ObjectDataSourceLabelCategory"

OnItemsRequested= "RadComboBoxLaborCatDesc_ItemsRequested"

AutoPostBack="false"

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>
