Custom Icon

FlexGrid displays various icons during its operations such as sorting, filtering etc. These icons can be changed using various icon templates provided in the FlexGrid control. These icon templates can be accessed through following properties.

Properties	Description
SortAscendingIconTemplate	Allows you to set the template of sort icon for sorting values in ascending order.
SortDescendingIconTemplate	Allows you to set the template of sort icon for sorting values in descending order.
GroupExpandedIconTemplate	Allows you to set the template which is used to create the icon displayed when the group is expanded.
GroupCollapsedIconTemplate	Allows you to set the template which is used to create the icon displayed when the group is collapsed.
EditIconTemplate	Allows you to set the template which is used to create the icon displayed in the header when a row is being edited.
NewRowIconTemplate	Allows you to set the template which is used to create the icon displayed in the header of a new row.
DetailCollapsedIconTemplate	Allows you to set the template which is used to create the icon displayed when the detail is collapsed.
DetailExpandedIconTemplate	Allows you to set the template which is used to create the icon displayed when the detail is expanded.

You can change the icons set by these templates either to the built-in icons provided by the FlexGrid or to your own custom image, geometric figures, font etc as an icon.

FlexGrid also allows you to change the appearance of the different icons used in the control using the C1Icon class. The C1Icon class is an abstract class that provides a series of different objects that can be used for displaying monochromatic icons which can easily be tinted and resized. You can also change the position of these icons by setting the SortIconPosition property.

C#	Copy Code
grid.SortIconPosition = GridSortIconPosition.Left;

Using built-in Icons

To set the built-in icons for the abovementioned templates, you can set the following properties of the C1IconTemplate class.

Icon	Image
Edit
Asterisk
ArrowUp
ArrowDown
ChevronUp
ChevronDown
ChevronLeft
ChevronRight
TriangleNorth
TriangleSouth
TriangleEast
TriangleWest

For instance, to change the default sort ascending icon to a built-in icon, for example, TriangleNorth, use the following code:

C#	Copy Code
grid.SortAscendingIconTemplate = C1IconTemplate.TriangleNorth;

Using Custom Icons

FlexGrid also allows you to set your own custom image, font, or path as an icon through the respective classes.

Icon Type	Icon Class Name
Bitmap/Image	C1BitmapIcon class
Font character	C1FontIcon class
Path	C1PathIcon class (child class of C1VectorIcon class)

For instance, to change the default sort descending icon to a custom image, use the following code:

In C#

C#	Copy Code
grid.SortDescendingIconTemplate = new C1IconTemplate(() => { return  new C1BitMapIcon{ Source = “arrow_down.png” }; });
