Namespace: DevExpress.XtraVerticalGrid.Rows

Assembly: DevExpress.XtraVerticalGrid.v19.1.dll

Declaration

C#

public void RemoveAt(
    int index
)

VB.NET

Public Sub RemoveAt(
    index As Integer
)

Parameters

Name	Type	Description
index	Int32	An integer value representing the index of the MultiEditorRowProperties object in the row item collection to remove.

Remarks

Use the Remove method to remove a row item representing an individual row properties object for a multi-editor row from the row’s MultiEditorRow.PropertiesCollection at the specified position.

Elements following the removed element move up to occupy the vacated area. The indexes of the moved elements are updated.

Note that the VGridControlBase.RowChanged event occurs each time after a row item is successfully removed from the collection. The event parameter’s RowChangedEventArgs.ChangeType property representing the type of row processing performed returns the RowChangeTypeEnum.PropertiesDeleted value.

If you wish to remove a specifc row item from the collection, use the MultiEditorRowPropertiesCollection.Remove method. All row items can be removed from the collection by using the MultiEditorRowPropertiesCollection.Clear method.

You can use the MultiEditorRowPropertiesCollection.Add method to add new row item objects to the collection. Existing row items can be added to the collection with the help of the MultiEditorRowPropertiesCollection.AddRange method.

Example

The example below represents a function that uses the MultiEditorRowPropertiesCollection.RemoveAt method and MultiEditorRowPropertiesCollection.Count property to remove the last row item from the MultiEditorRow.PropertiesCollection of a multi-editor row.

C#

private bool RemoveLastRowItem(BaseRow row) {
    // checking whether the passed row is of the multi editor type
    if (row.XtraRowTypeID != 2) return false;
    MultiEditorRowPropertiesCollection propsCollection = 
      (row as MultiEditorRow).PropertiesCollection;

    // checking whether the collection of row items is not empty
    if (propsCollection.Count == 0) return false;

    // removing the last row item from the collection
    propsCollection.RemoveAt(propsCollection.Count - 1);
    return true;
}

VB.NET

Private Function RemoveLastRowItem(ByVal Row As BaseRow)
    ' checking whether the passed row is of the multi editor type
    If Row.XtraRowTypeID <> 2 Then Return False
    Dim PropsCollection As MultiEditorRowPropertiesCollection = _
      CType(Row, MultiEditorRow).PropertiesCollection

    ' checking whether the collection of row items is not empty
    If PropsCollection.Count = 0 Then Return False

    ' removing the last row item from the collection
    PropsCollection.RemoveAt(PropsCollection.Count - 1)
    Return True
End Function
