TreeListNode.SetValue(Object, Object) Method

Sets the value for a specific column.

Namespace: DevExpress.XtraTreeList.Nodes

Assembly: DevExpress.XtraTreeList.v23.2.dll

NuGet Packages: DevExpress.Win.Navigation, DevExpress.Win.TreeList

Declaration

C#

public virtual void SetValue(
    object columnID,
    object val
)

VB.NET

Public Overridable Sub SetValue(
    columnID As Object,
    val As Object
)

Parameters

Name	Type	Description
columnID	Object	An object that identifies a column (a TreeListColumn object, field name, column’s absolute index or corresponding DataColumn object).
val	Object	The value to set for a specific column in the current node.

Remarks

The following objects and values can be passed as column identifiers:

• TreeListColumn object
• TreeListColumn.FieldName value
• TreeListColumn.AbsoluteIndex value
• System.Data.DataColumn object (when TreeList.DataSource represents the System.Data.DataView or System.Data.DataTable source)

Example

The next example demonstrates how to access a focused node value in the column which is identified by the TreeListColumn.AbsoluteIndex property set to 0.

Two ways are provided to perform this operation: via the TreeListNode.Item property and TreeListNode.SetValue method.

C#

//first method
treeList1.FocusedNode.SetValue(0, "new value");
//second method
treeList1.FocusedNode[0] = "new value";

VB.NET

'first method
TreeList1.FocusedNode.SetValue(0, "new value")
'second method
TreeList1.FocusedNode(0) = "new value"
