GridExportCustomizeCellEventArgs.DataItem Property

Returns the data source item that is bound to the data row being processed.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public object DataItem { get; }

Property Value

Type	Description
Object	If the processed cell belongs to a data row, the property returns a data item bound to this row. Otherwise, the property returns null.

Remarks

Use the DataItem property to get the data source item that is bound to the data row being processed. If the current cell does not belong to a data row (the AreaType property returns a value other than DataArea), the DataItem property returns null.

Pass the DataItem property value to the GetDataItemValue method to get the item’s field value when the Grid is bound to one of the following data sources:

• An Instant Feedback Data Source whose AreSourceRowsThreadSafe option is set to false (its default value)
• A collection of anonymous objects

In other cases, you can cast the DataItem property value to the corresponding type and use the {DataItem.FieldName} notation to get the item’s field value.

The following code snippet adds hyperlinks to the exported grid cell values.
