Prevents visual and internal data updates until the ColumnView.EndSort method is called.
Namespace : DevExpress.XtraGrid.Views.Base
Assembly : DevExpress.XtraGrid.v25.2.dll
NuGet Packages : DevExpress.Win.Grid, DevExpress.Win.Navigation
public void BeginSort()
Public Sub BeginSort
This method is equivalent to the ColumnView.BeginDataUpdate method. See this topic to learn more.
The code sample below iterates through grid records and reduces the “Price” column values by 10 percent.
private void UpdatePrice(DevExpress.XtraGrid.Views.Base.ColumnView View) {
// Obtain the Price column.
DevExpress.XtraGrid.Columns.GridColumn col = View.Columns.ColumnByFieldName("Price");
if (col == null) return;
View.BeginSort();
try {
// Obtain the number of data rows.
int dataRowCount = View.DataRowCount;
// Traverse data rows and change the Price field values.
for (int i = 0; i < dataRowCount; i++) {
object cellValue = View.GetRowCellValue(i, col);
double newValue = Convert.ToDouble(cellValue) * 0.9;
View.SetRowCellValue(i, col, newValue);
}
} finally { View.EndSort(); }
}
Private Sub UpdatePrice(ByVal View As DevExpress.XtraGrid.Views.Base.ColumnView)
' Obtain the Price column.
Dim Col As DevExpress.XtraGrid.Columns.GridColumn = View.Columns.ColumnByFieldName("Price")
If Col Is Nothing Then Exit Sub
View.BeginSort()
Try
' Obtain the number of data rows.
Dim DataRowCount As Integer = View.DataRowCount
' Traverse data rows and change the Price field values.
Dim I As Integer
For I = 0 To DataRowCount - 1
Dim CellValue As Object = View.GetRowCellValue(I, Col)
Dim NewValue As Double = Convert.ToDouble(CellValue) * 0.9
View.SetRowCellValue(I, Col, NewValue)
Next
Finally
View.EndSort()
End Try
End Sub
