    Hi, everyone.

    I added my items to RadListControl.
    Number of items is about 120.
    There are not many item but, each item need long loading time.
    So, it takes very long time util all items are loaded. (about 5~6sec)
    It is a critical problem!
    I think if only displayed items will be loaded, reduce first loading time.
    But, I can not find any event about item drawing or displaying.

    Please, help me.

    Hi,

    i think I know what you mean. If I do, then you could load the datasource in another thread and display a waiting or progress bar whilst the user is waiting.
    Or you could add in the items that will be visible, and then call DoEvents() though this can have some disadvantages.

    Is this the sort of thing you mean?
    Let me know if that helps or if you need more information
    Richard
