Remarks

The EditValueChanged event occurs when an end-user changes the cell value with an in-place editor and subsequently closes the editor. Handle the EditValueChanged event to save modified data to the data source.

Use the following properties to identify the edited cell:

• The e.ColumnField, e.RowField and e.DataField properties return column, row and data fields related to the current cell.
• The e.ColumnIndex and e.RowIndex properties return the zero-based index of the cell’s column or row. Note that the index is calculated based on visible rows or columns, thus collapsed and expanded rows/columns have different indexes.
• The e.ColumnValueType and e.RowValueType properties return column adn row types.
• If the current cell is a custom total cell, the e.ColumnCustomTotal and e.RowCustomTotal properties return column and row custom totals. Otherwise, these properties return null (Nothing in Visual Basic).

Use the EditValueChangedEventArgs.Editor property to access the in-place editor instance.

Example

This example demonstrates how to edit cells with the in-line cell editor and save the changes to the underlying data.

The Need Verification field is a boolean field displayed with a CheckEdit repository editor. The editor gets a value for display from the PivotGridControl.CustomCellValue event handler. When editing finishes, the PivotGridControl.EditValueChanged event handler calls the e.CreateDrillDownDataSource method to retrieve the underlying records and updates them.
