Changing style sheets and images
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.
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”.
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>.

This image file contains all icons displayed in grid.
The file contains 7 rows of images. The first three rows are 128 pixels high and the next four rows are 32 pixels height. You cannot change the height of these rows.
Remember, if you change width of any type of images by some <Img> attribute, like Tree, Line, Filter, … You must resize and move all images on the appropriate row.
The first three high rows contain images for building tree. To speed up rendering the first two rows contain all combinations of tree icons.
These two rows have images:
Where 0 and 1 are images of line (0 = empty, 1 = line). These images are all 21 pixels wide by default, this value can be changed by <Img Line=””> attribute.
L are images for end of line. These images are 26 pixels wide by default, this value can be changed by <Img Tree=””> attribute.
The third high row contains the rest of tree images like L image. These images are 26 pixels wide by default, this value can be changed by <Img Tree=””> attribute.
When displayed, the tree images are displayed as high as the row. If row if higher then 128 pixels, the tree image is repeated without first 32 pixels (vertically).
The last four rows contain other row images. The rows are 32 pixels high, but height of all these images is 17 pixels by default and can be changed by <Img Height=””> attribute.
In the fourth row are panel images. All these images must have the same width, defined in <Img Panel=””>. By default in Grid.gif have images height 13 pixels.
These images are in the order: S0 D0 S0 DX S1 D0 S1 DX SX D0 SX DX CC, where S is select, D is delete, 1 – selected, 0 - not selected, X – disabled. CC is copy icon.
In the fifth row are sorting images. All these images must have the same width, defined in <Img Sort=””>. By default in Grid.gif have images height 14 pixels.
In the sixth row are filter images. All these images must have the same width, defined in <Img Filter=””>. By default in Grid.gif have images height 17 pixels.
The seventh row contains two sections (changing width of one section does not affect the width or position of the other section).
The first six images are row content images (unchecked, checked, date picker, radio, checked radio, button defaults). All these images must have the same width, defined in <Img Row=””>. By default in Grid.gif have images height 17 pixels.
And next six images are tree images for use when tree lines are switched off by <Cfg NoTreeLines=’1’/>. These images are 26 pixels wide by default, this value can be changed by <Img Tree=””> attribute.
All images are in one row and must have the same width and height. The size is defined in input XML data <Img ToolbarHeight=”” ToolbarWidth=””> attribute. By default in Toolbar.gif have images width 16 and height 25 pixels.
