Hello,

Please put below code in your Page_load events and it still not working then put in Page_PreRender event and let me know its working in Page_PreRender or not ?

if (RadComboBox1.FindItemByValue(DateTime.Now.Month.ToString()) != null)
        {
            RadComboBox1.FindItemByValue(DateTime.Now.Month.ToString()).Selected = true;
        }
        else
        {
            // item not found
        }
 
        // or
 
        if (RadComboBox1.FindItemByText(DateTime.Now.Month.ToString()) != null)
        {
            RadComboBox1.FindItemByText(DateTime.Now.Month.ToString()).Selected = true;
        }
        else
        {
             // item not found
        }


Thanks,

Hi Pravati,

When checkboxes are used, you must set the Checked property of the combo item to true. Please review the following article for more details on the implementation and API for checkboxes, as they differ from the standard text and value: https://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/functionality/checkbox-support.
