Interface AutoFitRowRangeCallback

public interface AutoFitRowRangeCallback

Specifies the range of rows to consider in the calculation of automatic sizes for cells. Implement this callback in your application if you want finer control over the range of rows that the view uses than is possible through the AutoFitRowCount property. If no callback is registered with the GridView, then view uses the value of AutoFitRowCount to determine the number of rows it considers in calculating sizes.

Method Detail

startAutoFit

public Range startAutoFit(int row)

Specifies the range of rows to consider when calculating sizes of cells in a GridView. The GridView calls this at the start of an autofit operation.

• If the first row in the returned range is less than zero, then the Gridview uses row zero as the first row in the range.
• If the last row in the returned range is greater than the last row in the data source, then the GridView uses the last row in the data access as the last row in the range.
• If the first row is greater than the last row, then the range is considered invalid, and no automatic size calculation takes place.
• If this method returns a null range, then the view uses the value of the AutoFitRowCount to determine the range of rows to consider.

Parameters:

row - The first visible row of the GridView. If the GridView is not visible, then the GridView passes the the first row of the DataSource, which is row zero.

Returns:

The range of rows, inclusive, to use in calculating the automatic sizes.

endAutoFit

public void endAutoFit()

The GridView calls this method after it has finished calculating the automatic sizes.
