VGridControlBase.GetCellValue(MultiEditorRow, Int32, Int32) Method

Returns the value of a cell in a multi-editor row.

Namespace: DevExpress.XtraVerticalGrid

Assembly: DevExpress.XtraVerticalGrid.v21.2.dll

Declaration

public virtual object GetCellValue(
    MultiEditorRow meRow,
    int recordIndex,
    int cellIndex
)

Parameters

Name Type Description
meRow MultiEditorRow

The row that contains the cell.

recordIndex Int32

The index of the record that contains the cell.

cellIndex Int32

The index of the cell in a multi-editor row.

Returns

Type Description
Object

An object that specifies the cell’s value. null (Nothing in Visual Basic) if no cell is found.

Remarks

Use the GetCellValue or SetCellValue method to obtain or set a cell value. To identify the cell, use the field name (which specifies a row) and record index (which specifies a column). You can also use an EditorRow, MultiEditorRow, or RowProperties object to specify a row. For multi-editor rows (which display multiple cells in a single column), you should also specify the cell index. The image below illustrates cells in a single- and multi-editor row.

image

// Cell is identified by a field name and record index.
vGridControl.SetCellValue(fieldName: "Name", recordIndex: 0, value: "Touareg");
// Cell is identified by a single-editor row object and record index.
vGridControl.SetCellValue(gridRow: erName, recordIndex: 0, value: "Touareg");
// Cell is identified by a multi-editor row object, record index and cell index.
vGridControl.SetCellValue(meRow: merTransmmision, recordIndex: 0, cellIndex: 1, value: 8);
// Cell is identified by a row properties object and record index.
vGridControl.SetCellValue(props: merpTransmissionSpeeds, recordIndex: 0, value: 8);

If you obtain or set the focused row’s value, check if the focused row is an EditorRow or MultiEditorRow, and then use the method’s corresponding overload.

string focusedCellValue = string.Empty;
if (vGridControl1.FocusedRow is DevExpress.XtraVerticalGrid.Rows.EditorRow)
   focusedCellValue = vGridControl1.GetCellValue(vGridControl1.FocusedRow, vGridControl1.FocusedRecord).ToString();

Important

If the specified value’s type and the data field’s type do not match, the InvalidValueException event is raised. See the following topic for more information: Validation.

Example

The following sample code handles the VGridControlBase.CellValueChanged event to sum up the prices of the selected games in the purchase order list.

GetCellValue_SetCellValue

using DevExpress.XtraVerticalGrid;
using DevExpress.XtraVerticalGrid.Rows;
using DevExpress.XtraVerticalGrid.Events;

private void vGridControl1_CellValueChanged(object sender, CellValueChangedEventArgs e) {
   double sum = 0;
   BaseRow row = vGridControl1.GetFirst();
   while (vGridControl1.GetNext(row) != null){
      if (row.XtraRowTypeID == 2){
         if (Convert.ToBoolean(vGridControl1.GetCellValue(row as MultiEditorRow, 0, 0)) == true)
            sum += Convert.ToDouble(vGridControl1.GetCellValue(row as MultiEditorRow, 0, 1));
      }
      row = vGridControl1.GetNext(row);
   }
   vGridControl1.SetCellValue(rowPrice, 0, sum);
}
