Best Fit Minimum Width

Sort Order

Sort Index

Specifies the index of the current column within sorted columns. This property specifies the column's position within the Tree List control's "Sorted Columns" collection. End-users can add or remove columns from this collection by clicking column headers while holding down the [Shift] and [Ctrl] keys. Setting the "Sort Index" property to –1 removes the column from the Sorted Columns collection, and sets the column's "Sort Order" property to None. The Sorted Columns collection stores columns whose "Sort Order" property is other than None. The order of columns in the collection defines the sorting hierarchy.

Band Index

Specifies the band that contains the column. The band is identified by its index within the Tree List control's Bands collection. To remove a column from its band, set the "Band Index" property to –1. As a result, the column will be hidden in the Tree List control. To access the properties of a band containing a particular column, use the Band property.

Column Index

Specifies the horizontal position of the column within its band

Line Count

Specifies the column header's height, in text lines

Row Index

Specifies the vertical position of the column within its band. Use this property to stack columns within a band. Once assigned, the Row Index property value identifies a band row containing the current column. This value is equal to the number of columns that are stacked on the column.

 

The image below shows stacked columns and their Column Index and Row Index property values.
