Methods
CancelAddNewRow()
Cancels the new row addition process and reverts any changes made during the editing session. This method removes any bound row from the data source and resets the new row to its initial state.
Declaration
public void CancelAddNewRow()CompareToSystemRowInfo(GridViewSystemRowInfo)
Compares this new row with another system row to determine their relative ordering. New rows are positioned after table header rows but before filtering rows.
Declaration
protected override int CompareToSystemRowInfo(GridViewSystemRowInfo row)Parameters
|
GridViewSystemRowInfo
row
The GridViewSystemRowInfo to compare with. |
Returns
|
System.Int32
A value indicating the relative order: 1 if this row should come after the specified row, -1 if this row should come before the specified row, or 0 if they are equivalent. |
Overrides
EndAddNewRow()

Declaration
public GridViewRowInfo EndAddNewRow()Returns
|
GridViewRowInfo
The GridViewRowInfo that was successfully added to the grid, or null if the operation was canceled or failed. |
InitializeNewRow()
Initializes the new row for user input by setting up default values and preparing the row for editing. This method handles both data-bound and virtual scenarios, creates bound rows when necessary, and raises the DefaultValuesNeeded event to allow setting default values.

Declaration
protected override bool OnEndEdit()Returns
|
System.Boolean
True if the new row was successfully added; otherwise, false. |
Overrides
OnPropertyChanged(PropertyChangedEventArgs)
Called when a property value changes on this new row. Handles special logic for current state changes and row position updates, including cleanup of bound rows when the row loses focus.
