SortColumns()

Sorts the task cards in a specified column. Note that the sorting in TaskBoard is a one-time operation, and once performed, changes in the state of the RadTaskBoardColumnElement objects are not monitored, as this would lead to inconsistent behavior and break other control functionality such as drag and drop.

Declaration
public void SortColumns()
Remarks

The sort operation will use the default ColumnComparer, which sorts the RadTaskBoardColumnElements by the Title property. If you need custom sorting to be applied you need to create a custom comparer and assign it to the ColumnComparer property.

SortTasks()

Sorts the task cards in all columns. Note that the sorting in TaskBoard is a one-time operation, and once performed, changes in the state of the RadTaskCardElement objects are not monitored, as this would lead to inconsistent behavior and break other control functionality such as drag and drop.

Declaration
public void SortTasks()
Remarks

The sort operation will use the default TaskCardComparer, which sorts the RadTaskCardElements by the TitleText property. If you need custom sorting to be applied for speciffic column(s) you need to create a custom comparer and assign it to the TaskCardComparer property.

SortTasks(RadTaskBoardColumnElement)

Sorts the task cards in a specified column. Note that the sorting in TaskBoard is a one-time operation, and once performed, changes in the state of the RadTaskCardElement objects are not monitored, as this would lead to inconsistent behavior and break other control functionality such as drag and drop.

Declaration
public void SortTasks(RadTaskBoardColumnElement column)
Parameters
RadTaskBoardColumnElement column

The column whoose task cards will be sorted.
Remarks

The sort operation will use the default TaskCardComparer, which sorts the RadTaskCardElements by the TitleText property. If you need custom sorting to be applied for the soecified column you need to create a custom comparer and assign it to the TaskCardComparer property.
