Property Value

Type	Description
Boolean

true if a specific row contains one or more child rows; otherwise false.

Remarks

Use this property to determine whether the current row has child rows. If the row’s BaseRow.ChildRows collection is not empty, the HasChildren property will return true.

Example

The following sample code expands all collapsed parent rows at the root level and collapses expanded ones. The BaseRow.Expanded property is used for this purpose. The collection of root level rows is accessed via the VGridControlBase.Rows property. The BaseRow.HasChildren property is used to determine whether a row is a parent one and can be expanded or collapsed.

The image below displays the look & feel of a grid control before and after execution of the sample code.

C#
VB.NET

csharp

foreach (BaseRow currRow in vGridControl1.Rows) {
    // collapsing expanded parent rows or expanding collapsed ones
    if (currRow.HasChildren) currRow.Expanded = !currRow.Expanded;
}

Dim CurrRow As BaseRow
For Each CurrRow In VGridControl1.Rows
' collapsing expanded parent rows or expanding collapsed ones
    If CurrRow.HasChildren Then CurrRow.Expanded = Not CurrRow.Expanded
