[Solved] LoadOnDemand Default Value

[Atlas]

I am using the LoadOnDemand Combo example you provided:

 

<telerik:RadComboBox ID="RadComboBox1" runat="server" Width="250px" Height="150px"

 

 

 

EmptyMessage="Select a Company" EnableLoadOnDemand="True" ShowMoreResultsBox="true"

 

 

 

EnableVirtualScrolling="true" OnItemsRequested="RadComboBox1_ItemsRequested">

 

 

 

</telerik:RadComboBox>

 

 

 

protected void RadComboBox1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

 

{

 

 

DataTable data = GetData(e.Text);

 

 

 

int itemOffset = e.NumberOfItems;

 

 

 

int endOffset = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count);

 

e.EndOfItems = endOffset == data.Rows.Count;

 

 

 

for (int i = itemOffset; i < endOffset; i++)

 

{

RadComboBox1.Items.Add(

 

new RadComboBoxItem(data.Rows[i]["CompanyName"].ToString(), data.Rows[i]["CompanyName"].ToString()));

 

}

 

e.Message = GetStatusMessage(endOffset, data.Rows.Count);

}

 

This combobox is going to appear on an edit page, and I need to set the default selected value when the page loads. How do I do that?

My problem is very similar to this: http://www.telerik.com/community/forums/aspnet-ajax/combobox/selectedvalue-and-loadondemand.aspx

The control is in a FormView, but the control is attempting to bind when the page loads and the RadComboBox1_ItemsRequested event has not fired.  If I am only pulling back a subset of records, how does it no to get the item that matches the existing value?

Hello Nano Sacay,

Please find attached a sample project. It uses a load on demand RadComboBox in FormView.

I hope this will get you started.
