Enables you to prevent a card from being edited.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.2.dll

Declaration

C#

public event ASPxStartCardEditingEventHandler StartCardEditing

VB.NET

Public Event StartCardEditing As ASPxStartCardEditingEventHandler

Event Data

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

Property	Description
Cancel	Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs.
EditingKeyValue	Gets the processed card’s key value.

Remarks

The StartCardEditing event occurs when an end-user has clicked the Edit command or the ASPxCardView.StartEdit method has been called. To prevent switching the ASPxCardView to edit mode, set the event parameter’s Cancel property to true.

Example

The code example below prohibits a user from editing cards that contain information unrelated to the Sales department.

C#

string UserDepartment = "Sales";
...
protected void ASPxCardView1_StartCardEditing(object sender, DevExpress.Web.ASPxStartCardEditingEventArgs e)
{
    if (ASPxCardView1.GetCardValuesByKeyValue(e.EditingKeyValue, "Department").ToString() != UserDepartment) {
    e.Cancel = true;
}
