Hi,

we have radcombobox inside a user control (scheduler AdvancedEdit to be exact from a sample on your site). We are populating the RCB with values easily enough and passing a value to set the selected item as follows

 public int EventTypeId
        {
            get
            {
              
                    return Convert.ToInt32(ResrcbActivityType.SelectedValue);
               
            }

            set
            {
                try
                {
                    RadComboBoxItem itm = new RadComboBoxItem();

                    if (value > 0)
                        itm = ResrcbActivityType.FindItemByValue(Convert.ToString(value));
                    if (itm != null)
                    {
                        itm.Selected = true;
                    }
               
                }
                catch (Exception ex)
                {
                }
                
            }
        }

When debugging the value when we set is non zero which is correct, the itm object is a valid radComboBoxItem object and itm.Selected = true; evaluates without error. However, the first item in the radcomboBox list is always displayed no matter what. I am guessing this is something stupid - please anyone?

Hi Karl,

Thank you for contacting us.

From what you have provided as a code snippet, it seems that you are trying to select an items which is not in the items collection of the RadCombobox, but having only a reference to such an item.

In order to select the desired item change your code as following:

I hope this would help you out.
