Bad ScreenTip on First Display

[Jeremy Murtishaw]

Hello,

I've noticed a problem with screen tips, specifically in GridViews, that I can't get rid of. Basically, the first time that a screen tip is shown for a given grid, it displays with improper sizing and causes visual artifacts on the screen. Subsequent displays of the same screen tip are fine. I am certain that no code or relevant variables are changing. Also, somehow this problem is occurring throughout my application, even when the code customizing the screen tip is completely different. Please see the attached screenshots. The first and third are examples of the problem, the second is the same as the first, but on a subsequent screen tip.

Thanks!

Jeremy

Figured you might want some example code. This is what generated the third example below. Again, it works fine on subsequent tries.

GridDataCellElement cell = e.Item as GridDataCellElement;
                if (cell != null && cell.RowInfo != null && cell.RowInfo is GridViewDataRowInfo)
                {
                    if (cell.ColumnIndex == (int)Event.Column.Description)
                    {
                        string sValue = cell.Text;
                        if (sValue == "")
                            return;
                        RadOffice2007ScreenTipElement screenTip = new RadOffice2007ScreenTipElement();
                        screenTip.CaptionLabel.Text = string.Empty;
                        screenTip.MainTextLabel.Text = sValue;
                        screenTip.MainTextLabel.AutoSize = false;
                        //screenTip.MainTextLabel.AutoSizeMode =  RadAutoSizeMode.FitToAvailableSize;
                        screenTip.AutoSize = false;
                        screenTip.EnableCustomSize = true;
                        int iHeight = 34;
                        screenTip.MainTextLabel.Size = new Size(grdEvents.Columns[(int)Event.Column.Description].Width + 140, iHeight);
                        screenTip.MainTextLabel.PositionOffset = new SizeF(-2f, -4f);
                        screenTip.Size = new Size(grdEvents.Columns[(int)Event.Column.Description].Width + 150, iHeight);
                        //screenTip.MainTextLabel.Size = new Size(240, 45);
                        screenTip.MainTextLabel.TextWrap = true;
                        cell.ScreenTip = screenTip;
                    }

                }

Hello Jeremy Murtishaw,

If you want to set a custom size to RadScreenTip, you should use the EnableCustomSize property that we exposed for such purposes. However, please note that you should not modify the AutoSize property. This will allow you to use RadScreenTip without any issues.

Hi Nikolay,

Your solution has helped, but it is not fixing the problem 100%. Although there are no ugly gray areas any more, the size of the tooltip is still defaulting to a nearly square rectangle on the first display, and my custom size is not being applied until the second display. Could you try to help with this symptom as well?

I've attached two screen shots. One of the first display, including the defaulted size and clipped text, and one of the second display, which looks perfect.

Thanks!

Jeremy

Hi Jeremy Murtishaw,

Thank you for bringing this issue to our attention. I was able to reproduce it. We will address it in one of our next releases. However, I am not able to provide you with a workaround for the time being.

I have updated your Telerik points for the report.

Kind regards,

Hi Nikolay,

Any chance this will be fixed in Q1 2010? I am seeing this pervasively throughout all of my telerik controls. It doesn't matter whether it's a button, Scheduler, or Grid, it always has the wrong default size the first time the screentip loads. A fix would be very much appreciated.
