thank you

Hello lamees,

Thank you for contacting me.

Currently we do not support this feature. We will consider adding it in our Q1 2008 release.

Do not hesitate to write me, if you need further assistance.

Hello lamees,

Thank you for getting back to me.

We plan to release the Q1 2008 version of RadControls for WinForms in the beginning of April. We will highly appreciate if you send us a summary list of the features you expect to see in this release.

Let me know, if you have other questions.

I am currently running the Q1 2009 release.  Was the functionality to hide/show the plus sign ever implemented?  If so, what is the property to turn it off or how do I do it?

Thanks,

LK

Hi lkeel,

Thank you for this questions.

Yes this functionality is available with Q1 2009 of RadControls for WinForms. You could use the code below to hide the "+" sign where no child rows are available:

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridGroupExpanderCellElement && e.CellElement.RowElement is GridDataRowElement)
    {
        GridViewRowInfo[] rows = e.CellElement.RowInfo.ViewTemplate.ChildGridViewTemplates[0].GetChildRows(e.CellElement.RowInfo);
        e.CellElement.ShouldPaint = rows != null && rows.Length > 0;
    }
}

I hope this helps. Should you have any other questions, don't hesitate to write us.

Best wishes,
