ColumnView.GetRowCellValue(Int32, String) Method

Gets the value of the specified cell in the grid's data source.

Namespace:DevExpress.XtraGrid.Views.Base
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Parameters

rowHandle
Type: Int32
An integer value representing the handle of the row in which the desired cell resides.
fieldName
Type: String
A string representing the field name whose value is to be returned. This parameter can refer to any field in the data source, even if the current View does not contain a GridColumn referring to this field. A System.NullReferenceException exception will be thrown if the underlying data source does not contain the specified field.

Return value

Type: Object
An object representing the specified cell's value.

Expanded Remarks

This method returns null (Nothing in Visual Basic) if the specified row handle doesn't point to any of the rows within the current View or points to a group row.

To get the displayed value of a cell, the GetRowCellDisplayText method can be used.

For more information on row handles, refer to the Identifying Rows and Cards document.

Note

In Instant Feedback Mode (async server mode), this GetRowCellValue method has limitations. It returns a correct value only if the target row has been loaded. Otherwise, it returns a "Non-loaded Value". You can check to see whether or not the returned value is the "Non-loaded Value" by calling the BaseEdit.IsNotLoadedValue static method.

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the GetRowCellValue member must not be invoked for these Views. The GetRowCellValue member can only be used with real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.
