Changing format of autocomplete list

[Jason Gaylord]

I've changed the look and feel of the normal dropdownlist by handling the VisualListItemFormatting event. However, how can I change the look of the items shown when using autocomplete?

Hi,

As far as I know, this is not possible as the textbox item part of the drop down is the same as the RadTextBox.. Have a look at my answer in this forum post for more information.

Makes sense. I see a feature request here. :)

Hello Rowen,

Thank you for writing.

You can handle the PopupOpened event and the VisualItemFormatting event to change the look and feel of the items. The following code snippet demonstrates this:

radDropDownList1.DropDownListElement.AutoCompleteSuggest.DropDownList.VisualItemFormatting += new VisualListItemFormattingEventHandler(DropDownList_VisualItemFormatting);

radDropDownList1.DropDownListElement.AutoCompleteSuggest.DropDownList.PopupOpened += new EventHandler(DropDownList_PopupOpened);

void DropDownList_PopupOpened(object sender, EventArgs e)
{
            foreach (RadListVisualItem item in ((RadDropDownListElement)sender).ListElement.ViewElement.Children)//loop troughs visual items
            {
                item.BackColor = Color.Red;
            }
}

void DropDownList_VisualItemFormatting(object sender, VisualItemFormattingEventArgs args)
{
            args.VisualItem.BackColor = Color.Red;
            Debug.WriteLine(args.VisualItem.Text);
}

Hope this helps. Should you have any further questions, feel free to ask.

All the best,
