How to: Specify Different In-place Editors to Use in Display and Edit Modes

The following example demonstates how to assign different in-place editors to a column that will be used in display and edit modes respectively.

Assume that a grid column displays integer values that should be represented by a progress bar in display mode. In edit mode, a cell's value must be edited by a spin editor. To implement this task, a ProgressBar in-place editor must be assigned as the default editor to the column via the GridColumn.ColumnEdit property. This editor will be used to represent data in display mode. To provide a custom editor that will be used for in-place editing, the GridView.CustomRowCellEditForEditing event is handled.

The following image illustrates the result:

C#

using DevExpress.XtraEditors.Repository;

 

// In-place editors used in display and edit modes respectively.

RepositoryItem editorForDisplay, editorForEditing;

 

private void Form1_Load(object sender, EventArgs e) {

    // Initialize the editors and assign the default editor to a column.

    editorForDisplay = new RepositoryItemProgressBar();

    editorForEditing = new RepositoryItemSpinEdit();

    gridView1.GridControl.RepositoryItems.AddRange(

      new RepositoryItem[] { editorForDisplay, editorForEditing });

    gridView1.Columns["Quantity"].ColumnEdit = editorForDisplay;

}

 

// Provide the editor for in-place editing.

private void gridView1_CustomRowCellEditForEditing(object sender,

  CustomRowCellEditEventArgs e) {

    if (e.Column.FieldName == "Quantity")

        e.RepositoryItem = editorForEditing;

}

 

VB

Imports DevExpress.XtraEditors.Repository

' In-place editors used in display and edit modes respectively.

Dim editorForDisplay, editorForEditing As RepositoryItem

Private Sub Form1_Load(ByVal sender As System.Object, _ 

  ByVal e As System.EventArgs) Handles MyBase.Load

    ' Initialize the editors and assign the default editor to a column.

    editorForDisplay = New RepositoryItemProgressBar()

    editorForEditing = New RepositoryItemSpinEdit()

    gridView1.GridControl.RepositoryItems.AddRange( _

      New RepositoryItem() {editorForDisplay, editorForEditing})

    gridView1.Columns("Quantity").ColumnEdit = editorForDisplay

End Sub

' Provide the editor for in-place editing.

Private Sub gridView1_CustomRowCellEditForEditing(ByVal sender As System.Object, _

  ByVal e As DevExpress.XtraGrid.Views.Grid.CustomRowCellEditEventArgs) _

  Handles gridView1.CustomRowCellEditForEditing

    If e.Column.FieldName = "Quantity" Then

        e.RepositoryItem = editorForEditing

    End If

End Sub
