ASPxGridView.GetChildDataRow(Int32, Int32) Method

Returns a DataRow object that represents the specified row contained within the specified group.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v18.2.dll

Declaration

C#

public virtual DataRow GetChildDataRow(
    int groupRowVisibleIndex,
    int childIndex
)

VB.NET

Public Overridable Function GetChildDataRow(
    groupRowVisibleIndex As Integer,
    childIndex As Integer
) As DataRow

Parameters

Name	Type	Description
groupRowVisibleIndex	Int32	An integer value that identifies a group row by its visible index.
childIndex	Int32	An integer value that identifies a data row within the group by its index.

Returns

Type	Description
DataRow	A DataRow object that represents the specified row contained within the specified group.

Remarks

The GetChildDataRow method allows you to obtain a data row contained within the specified group row. The group row is identified by its visible index. A data row is obtained by its index within the group. To obtain the number of data rows contained within the specified group, use the ASPxGridView.GetChildRowCount method.

Note

Since the GetChildDataRow method returns a DataRow object, it requires the bound data source support this type of object (e.g. Access Data Source, SQL Data Source). If the bound data source does not support DataRow objects, the GetChildDataRow method returns null (Nothing in Visual Basic). In this case, you can use the ASPxGridView.GetChildRow method to get an object that represents the specified row.
