Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.1.dll

NuGet Package: DevExpress.Web

Declaration

C#

public event ASPxCardViewEditorEventHandler CellEditorInitialize

VB.NET

Public Event CellEditorInitialize As ASPxCardViewEditorEventHandler

Event Data

The CellEditorInitialize event's data class is ASPxCardViewEditorEventArgs. The following properties provide information specific to this event:

Property	Description
Column	Gets the data column whose cell editor is being initialized.
Editor	Gets the editor currently being processed. Inherited from ASPxGridEditorEventArgs.
KeyValue	Gets the card key value - an object that uniquely identifies the card.
Value	Gets the editor’s value. Inherited from ASPxGridEditorEventArgs.
VisibleIndex	Gets the edited card’s visible index.

Remarks

The CellEditorInitialize event is raised when the ASPxCardView is switched to edit mode and enables you to initialize cell editors.

Note

• Since the CellEditorInitialize event works correctly only when a request is sent to the server to initialize an editor, this event will not be raised after you start editing a new row in Batch edit mode because in this mode, requests are not sent to the server when an editor is activated.
• The CellEditorInitialize event affects only the edit mode settings (when editors are visible).
• The CellEditorInitialize event isn’t raised for edit cells that contain custom editors defined using templates.
• The CellEditorInitialize event fires only for built-in column editors.

Examples

• The following example illustrates how to use the CellEditorInitialize event to automatically focus the required column’s editor using the editor’s ASPxWebControl.Focus method (the e.Editor event argument).

  C#

  protected void ASPxCardView1_CellEditorInitialize(object sender,
      DevExpress.Web.ASPxCardViewEditorEventArgs e) {
      if (e.Column.FieldName == "TimeFrom")
      {
          e.Editor.Focus();
      }
  };
  

• This example demonstrates how to prevent an end-user from changing the unit price. To do this, the CellEditorInitialize event is handled. If the processed edit cell corresponds to a column bound to the ‘UnitPrice’ data field, its editor’s ReadOnly property is set to true.

  C#

  protected void ASPxCardView1_CellEditorInitialize(object sender,
      DevExpress.Web.ASPxCardViewEditorEventArgs e) {
      if (ASPxGridView1.IsNewCardEditing) return;
      if (e.Column.FieldName == "UnitPrice")
          e.Editor.ReadOnly = true;
  }
