MultiColumnComboBox - Turn off grid lines

[Paul]

How can I turn off the grid lines in a MultiColumnComboBox?

Thanks,

Hello Paul,

Thank you for writing. 

To do that you can use the ViewCellFormatting event of the inner grid:

radMultiColumnComboBox1.EditorControl.ViewCellFormatting += EditorControl_ViewCellFormatting;

void EditorControl_ViewCellFormatting(object sender, CellFormattingEventArgs e)
        {
            e.CellElement.DrawBorder = false;
        }

I hope this helps.

Thanks Stefan, that did the trick!

How about if I'd like to only show the vertical lines?

Hello Paul,

Here you are:

void EditorControl_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    e.CellElement.BorderTopWidth = 0;
    e.CellElement.BorderBottomWidth = 0;
}

I hope this helps.

Stefan,

Using that code, my dropdown still has horizontal lines.  Sample attached.

Let's try this attachment again.

Well, just like Telerik's products, their website refuses to work properly.  Here's a link to the sample.

Hi Paul,

Different themes have different styling for the borders. My previous reply was based on the default theme for the suite. I did not know that you were using the TelerikMetroBlue theme. The latter is using a single border for the cells, rather than four borders, hence the previous snippet did not work for it. Please give the following approach a try:

void EditorControl_ViewCellFormatting(object sender, CellFormattingEventArgs e)
 {
     e.CellElement.BorderBoxStyle = BorderBoxStyle.FourBorders;

     e.CellElement.BorderTopWidth = 0;
     e.CellElement.BorderBottomWidth = 0;

     e.CellElement.BorderLeftColor = e.CellElement.BorderColor;
     e.CellElement.BorderRightColor = e.CellElement.BorderColor;
 }

In addition, may I please ask you what are the difficulties you had experienced with the site. What file (extension) you were trying to attach? How big was it?

I am looking forward to your reply.

Thanks Stefan, that works great.  I am using a custom theme, not the default.

I tried to upload a 7kb png file and a 7kb jpg file.  I received an error when posting, but the message did post, but without the attachment.
