Changing style sheets and images

TreeGrid v4.6

All TreeGrid style definitions are in one .css file, by default in Grid.css. You have to include the style sheet into HTML header.

To change TreeGrid styles is better to update existing .css files than to create new one, because there are many restrictions to preserve grid layout compact.

You can change individual styles in the .css file, but you must preserve all style names. You can also add new styles to use them in TreeGrid event OnGetClass.

To change CSS style for individual cell you can use its XML attributes ClassInner, ClassOuter and ClassEdit. Dynamically you can change CSS class in API event OnGetClass.

In Grid.css all style names starts with letter “G”. This is default prefix. To use more style sheets you need to use another prefix in other sheets and set it in input XML data to <Img Style=’G’/> attribute. In predefined style sheets are these prefixes: GridBigger “GB”, GridLight “GL”, GridGame “GG”.

By CSS styles you can define all visual properties except background color for cells. For setting cell/row background color use tag <Colors> in input XML. Or use cell or row attribute Color.

All TreeGrid images are in two files, one with all row images and one with toolbar images. By default these files are Grid.gif and Toolbar.gif.

You can change these files, but you must preserve image position and order. If you change sizes of images, you must update settings in XML input data, tag <Img>.

There also two cursor files for dragging. DragOne.cur and DragMore.cur. These files are not required.
