ScrollView(Int32)

Scrolls the view with a specified offset.

Declaration
public void ScrollView(int offset)
Parameters
System.Int32 offset

The offset.

ScrollView(Int32, Boolean)

Scrolls the view with a specified offset.

Declaration
public void ScrollView(int offset, bool buffered)
Parameters
System.Int32 offset

The offset.
System.Boolean buffered

If the method is called too often, set this to [true] to improve performance.

Sort()

Sorts the task cards added in the TaskCardCollection. Note that the sorting in the 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 Sort()
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.

UpdateScrollBar(SizeF)

Declaration
protected virtual void UpdateScrollBar(SizeF availableSize)
Parameters
System.Drawing.SizeF availableSize
