Undefined protocol in the URL cell

问题

I have a UltraGridCell with style equal to Infragistics.Win.UltraWinGrid.ColumnStyle.URL and add my own handler to UltraGrid.MouseClick so that I can open a new tab if the URL columns is clicked

Nothing is wrong if the URL column is of the value "ABCDE". It looks like a URL link in the cell with underline and blue color (turns purple after click). It just like a URL link in the browser.

The issue is that if the content is of the value like "ABC:DE". It turns out it complains that there is an undefined protocol is calling. Just like you enter "ABC://DE" at the IE URL bar.

After checking in the debug mode, it looks like that this should be called by UltraGrid internally. Hence, my question is: Is there any way for me to disable this default behaviour?

Any help is highly appreciated.

When you set the column style to Infragistics.Win.UltraWinGrid.ColumnStyle.URL the editor of the column becomes Infragistics.Win.FormattedLinkLabel.FormattedLinkEditor. This editor has LinkClicked event. In the event handler you can get OpenLink property of the event argument and set it to false. This will suppress link opening. To do so, first get the editor in the InitializeLayout event:

private void UltraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
    // get the column you will set up
    var column = e.Layout.Bands[YOUR_BAND_INDEX].Columns[YOUR_COLUMN_INDEX];

    // set the style of the column (you already did this)
    column.Style = Infragistics.Win.UltraWinGrid.ColumnStyle.URL;

    // get the editor after set the column style and handle LinkClicked event
    var editor = column.Editor as FormattedLinkEditor;
    editor.LinkClicked += this.Editor_LinkClicked;
}

Then in LinkClicked event stop link opening:

private void Editor_LinkClicked(object sender, Infragistics.Win.FormattedLinkLabel.LinkClickedEventArgs e)
{
    e.OpenLink = false;
}
