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");
