XamComboEditor Load On Demand
posted

Hi All,

We use Telerik Rad Controls in web application. In this application we use "RadComboBox" this is working fine, and our client demanding the same functionality in WPF application. In WPF we use Infragistics controls i use the "XamComboEditor" but unfortunately can't achieve the same functionality. Kindly help me how can i achieve  the same functionality with "XamComboEditor" or other controls? One important thing in "RadComboBox" is that "Web Service" is called at when user stop typing. This is major functionality i want, but in my case "Service" is called character by character i use binding with "Value" property of "XamComboEditor". Through this approach my code hit database again and again and database connections open alots in a 2 to 3 seconds. For reference i send you the Telerik link and image.

In this link we use third "RadComboBox"approach using "Web Service" We use MVVM in WPF Application and display multi-Columns in "XamComboEditor". We set the Total Records who want to display in "RadComboBox", suppose first time we display 10 records , when the records are displayed, on moving scroll bar up and down other records are displayed. See the link for further details. Our client demanding the same functionality kindly help me with sample application as soon as possible because i spent alot of time to achieve this functionality but not achieved, so in last i am contacting you.

Regards

Sufyan
