I tried to set the focus on a RadAutoCompleteBox in many different ways. Unfortunately nof them worked. Neither on server-side by RADAutoCompleteBox1.Focus() in the page_load Event, nor on client-side by using the OnClientLoad Event of the RACB. Any ideas how to get it done? I guess this is a bug as Setting Focus on other control works easily.
Use the following code:
//aspx:
<telerik:RadAutoCompleteBox
runat="server"
ID="RadAutoCompleteBox1"
DataSourceID="SqlDataSource1"
DataTextField="FirstName"
Width="280px"
DropDownWidth="280px"
InputType="Text"
Delimiter=";," >
</telerik:RadAutoCompleteBox>
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
ProviderName="System.Data.SqlClient" SelectCommand="SELECT [FirstName], [LastName], [EmployeeID] FROM [Employees]">
</asp:SqlDataSource>
//cs:
ScriptManager1.SetFocus("RadAutoCompleteBox1_Input");
