Summary0005204: TjvDBGrid and property FixedCols >0
Description1. Wrong rendering a font of fixed columns i.e. for a fixed columg using a font of the next column.

2. Rendering fixed columns with artefacts in D2010, if a property DrawingStyle <> gdsClassic (pic. err_D2010_grid.JPG).

3. If FixedCols >0 and a selected column is outside a visible grid, during changing width of any column there is a scrolling to the selected column. It's not conveneint when I need to set several columns. When FixedCols = 0 there is not the problem.
TagsNo tags attached.

Could you please provide the zipped sources of a sample application showing this?

After I upgrade my projects from D7 to D2010, all JvDBGrids with fixed columns become like the picture shown by svk12345. That is a frame outside each fixed cell which copy the back(of the form) color (look like transparent) when drawn.

Are there any quick fix on this issue? I know how to apply changes in the component sources code but I dont know how to fix this issue myself.

Thanks in advance.

Themed Grid rendering in Delphi 2010 and XE are now done by the original DBGrid. Maybe this fixes all the problems.

Unfortunately I can not check. SVN i is not available, and version 3.40 of these bugs are present. Test case in the attached file should all be clarified. Who can let check for the latest version of SVN.

I used TjvDBGrid and property FixedCols > 0 with Delphi 2010 on Windows 7.
With DrawingStyle = (gdsThemed, gdsGradient).
When the mouse rolls over the fixed cols, the black border lines of each cell change to white. When I click on the grid, border lines change to black again.
My opinion is better stay on white color.

With DrawingStyle = gdsClassic, NO PROBLEM.
