    I am using RadComboBox in my application. I have used Load On Demand feature when user scroll down in the list inside rad combo box. 
    Its working fine. I have used check box true inside the list item. 

    I have thousands of item in the list, So I have used Load on demand feature. I want use Search feature, so user can search by entering text in the combobox then they can find quickly particular records. for this things below is demo given by you...


    My problem is that when I am entering text in the combobox, text is stays just 1 or 1/2 seconds after that text is disappearing from the combobox.

    I have checked in the above demo url. You have not used Checkbox inside that list. When I remove checkbox from the list. Its working fine. I dont want to remove checkbox. As its a client requirement, I want to keep the selection of records from the list items.

    Please help me here.. I have lost my 6-7 hours to fix this issue today, but problem is still there.
    Please let me know what cause here.

    Hi Basharat,

    I am afraid that simultaneous usage of RadComboBox CheckBoxes feature and Load On Demand is not a supported scenario.
    The RadComboBox items loaded with Load On Demand are not accessible on server-side. However the CheckBoxes feature needs to access the checked RadComboBox items at server-side.
    Additionally when CheckBoxes is enabled – the user is not supposed to type in control input because the text in the input is set explicitly when a RadComboBox item is checked.

    Please find more details about CheckBoxes feature this at this help article.
