TGridColumn ControlType = ctHTML wrapping problem |

Allen Hunt | Hi,
This one is a little difficult to explain but I've included some screenshots. I have a TGridColumn with the ControlType set to ctHTML. And when I have a URL that exceeds the width of the column the text is shifted downward where the user doesn't see the top of the first line it gets cutoff. It appears when the text wraps the grid is not displaying the column results using a top left position. Please see the Grid Using ctHTML ControlType For TGridColumn png. I have it so when the user double clicks on the column it popups up a dialog to view how the text is suppose to look. I should note (as an fyi) on the grid I'm actually removing the line feeds in order to display as much text as possible. If I use a TGridColumn with the ControlType set to ctMultiLineEdit the behavior is fine however my goal is be be able to allow the user to click on urls (even if they don't see the full path) from within the grid so I think I really need to use a ControlType of ctHTML. I've include a screen shot Grid Using ctMultiLineEdit ControlType For TGridColumn png so you can see how it's working. Any tips to get the HTML text to display in the upper most top left position would be highly appreciated. Thank you!

Uli Becker | Allen,
> Any tips to get the HTML text to display in the upper most top left position would be highly appreciated. Thank you! The position is controlled by the matching interface and the interface's layout is set in the "UpdateWrap" procedure of TGridTextCell The only way I know is to modify this procedure: procedure TGridTextCell.UpdateWrap(AWrap: Boolean); begin FCaptionElement.Format.Wrap:=AWrap; if AWrap and (TGridColumn(Owner).ControlType=ctMultiLineEdit) then begin FCaptionElement.Layout.Position:=lpTopLeft; FCaptionElement.Layout.Stretch:=lsBottomRight; end else begin // FCaptionElement.Layout.Position:=lpLeftCenter; <------ Change FCaptionElement.Layout.Position:=lpTopLeft; <------ Change FCaptionElement.Layout.Stretch:=lsRight; end; end; @Tim: Maybe it would be a good idea to add that as an option (VerticalAlignment). Cheers Uli |

Uli Becker | Correction:
FCaptionElement.Layout.Stretch:=lsRight; should be FCaptionElement.Layout.Stretch:=lsBottomRight; in the modified code. |

Your are right: this should be the correct version of what I meant: if AWrap then begin FCaptionElement.Layout.Position:=lpTopLeft; FCaptionElement.Layout.Stretch:=lsBottomRight; end else begin FCaptionElement.Layout.Position:=lpLeftCenter; FCaptionElement.Layout.Stretch:=lsRight; end; Uli |
