      <para>The <see cref="E:System.Windows.Forms.DataGridView.CellErrorTextNeeded" /> event occurs only when the <see cref="T:System.Windows.Forms.DataGridView" /> control <see cref="P:System.Windows.Forms.DataGridView.DataSource" /> property is set or its <see cref="P:System.Windows.Forms.DataGridView.VirtualMode" /> property is true. Handling the <see cref="E:System.Windows.Forms.DataGridView.CellErrorTextNeeded" /> event is useful when you want to determine the error for a cell depending on its value or state. </para>
      <para>When you handle the <see cref="E:System.Windows.Forms.DataGridView.CellErrorTextNeeded" /> event and specify error text in the handler, an error glyph appears in the cell unless the <see cref="P:System.Windows.Forms.DataGridView.ShowCellErrors" /> property is set to false or the cell is in edit mode. When the user moves the mouse pointer over the error glyph, the error text appears in a ToolTip.</para>
      <para>The <see cref="E:System.Windows.Forms.DataGridView.CellErrorTextNeeded" /> event also occurs whenever the value of the <see cref="P:System.Windows.Forms.DataGridViewCell.ErrorText" /> property is retrieved. </para>
      <para>You can use the <see cref="P:System.Windows.Forms.DataGridViewCellEventArgs.RowIndex" /> and <see cref="P:System.Windows.Forms.DataGridViewCellEventArgs.ColumnIndex" /> property to determine the state or value of a cell, and use this information to change or modify the <see cref="P:System.Windows.Forms.DataGridViewCellErrorTextNeededEventArgs.ErrorText" /> property. This property is initialized with the value of the cell <see cref="P:System.Windows.Forms.DataGridViewCell.ErrorText" /> property, which the event value overrides. </para>
      <para>Handle the <see cref="E:System.Windows.Forms.DataGridView.CellErrorTextNeeded" /> event when working with large amounts of data to avoid the performance penalties of setting the cell <see cref="P:System.Windows.Forms.DataGridViewCell.ErrorText" /> value for multiple cells.

          <para>The <see cref="P:System.Windows.Forms.DataGridViewCellErrorTextNeededEventArgs.ErrorText" /> property value displays as a ToolTip for the error glyph in the cell.</para>
