    Hello John,

    Thank you for writing back.

    If I understand correctly you want to bind to a database that has image column and you want to display the images in RadListView. This can be achieved by using the CellFormatting event and setting the images there.

    Also you can check a particular column value and select the corresponding row like this:
    For i = 0 To RadListView1.Items.Count - 1
      
        If RadListView1.Items(i)(0) = "Robert" Then
            RadListView1.SelectedIndex = i
      
            MsgBox(i)
        Else
        End If
    Next

    Please refer to attached project for sample implementation of the described approaches.

    Off topic, there was a duplicate of this thread posted which was deleted.

    I hope this helps. Should you have any other questions do not hesitate to ask.

    Hi Thanks for your good answer tell them I'm using the property IconView radlistview to show pictures caratulas charge type and passing the datatable to datasource so radlistview same datamember and I use the ItemDataBound property to load the images such that when using your example, the scroll position is not always the selected item and disappear the last items of radlistview or scroll is shortened and can not move at the end of the items so whether you want to do is to press a button for example the letter "C 'selects the first item that begins with that letter eg "Carlos Vives" and the scroll is positioned on the item what was done with the find in listview visual studio hope you can help me thank you for taking the time to answer greetings.

    Hello John,

    Thank you for writing back.

    I am having difficulties understanding the text you wrote. Google translate is not an appropriate way to translate as it does not always provide the best possible translations. I would suggest that you consult an English speaker to compose your questions, in order for us to understand them and help you resolve them.

    If I understand you correctly you have a RadListView with ViewType set to IconsView. And if the user presses a character key the first item whоse text starts with this character to be selected (the listview should be scrolled to the item if necessary). I have updated the demo project to implement this functionality. I am just comparing the items text first character with the pressed one in the KeyPress event handler.

    I hope this information helps. Should you have any other questions, I will be glad to assist you.

    Good Day thanks for replying unfortunately I do not have a translator than google as the example above works but continues with the errors mentioned because when you press the keys on occasion the scrooll does not move to the right place and the scroll is shortened which causes the last items are hidden on this occasion hize modify your example and catch errors again thanks for taking the inconvenience of answering greetings.

    Hi John,

    Thank you for replying.

    If I understood your latest reply correctly, at some point the scrollbar's value becomes invalid and not all items are visible? If that is the case, then we have this issue logged in our database. It is caused by some miscalculations in our logic of calculating the size of the items. Moreover the issue has been addressed and if it passes our QA tests will be available in the next release. Currently, no workaround is available.

    Due to some technical difficulties we currently experience I cannot provide you with a link to the issue. As soon as these issues are resolved I will reply in this thread with the needed information.

    Let me know if there is anything else.

    Regards,
