DataGridView.UpdateCellErrorText Method

Forces the cell at the specified location to update its error text.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public void UpdateCellErrorText (
	int columnIndex,
	int rowIndex
)
public void UpdateCellErrorText (
	int columnIndex, 
	int rowIndex
)
public function UpdateCellErrorText (
	columnIndex : int, 
	rowIndex : int
)
Not applicable.

Parameters

columnIndex

The column index of the cell to update, or -1 to indicate a row header cell.

rowIndex

The row index of the cell to update, or -1 to indicate a column header cell.

Exception typeCondition

ArgumentOutOfRangeException

columnIndex is less than -1 or greater than the number of columns in the control minus 1.

-or-

rowIndex is less than -1 or greater than the number of rows in the control minus 1.

Use this method when you maintain cell error text yourself by handling the CellErrorTextNeeded event. Call this method when you change the stored error text for the specified cell. This will invalidate the cell, forcing the DataGridView control to retrieve the updated error text through the CellErrorTextNeeded event handler.

Although you can use this method to update errors for header cells, column header cells do not display error glyphs.
