ASPxGridView.StartRowEditing Event

Enables you to prevent a row from being edited.

Assembly : DevExpress.Web.v25.2.dll

Declaration

C#
VB.NET

csharp

public event ASPxStartRowEditingEventHandler StartRowEditing

Public Event StartRowEditing As ASPxStartRowEditingEventHandler

Event Data

The StartRowEditing event's data class is ASPxStartRowEditingEventArgs. 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 row’s key value.

Remarks

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

Example

The code sample below demonstrates how you can prohibit a user from editing data rows containing information unrelated to the Sales department.

C#
VB.NET
ASPX

csharp

string UserDepartment = "Sales";
...
protected void MyGridView_StartRowEditing(object sender, DevExpress.Web.Data.ASPxStartRowEditingEventArgs e) {
     if (MyGridView.GetRowValuesByKeyValue(e.EditingKeyValue, "Department").ToString() != UserDepartment) {
          e.Cancel = true;
     }
}

Dim UserDepartment As String = "Sales"
...
Protected Sub MyGridView_StartRowEditing(sender As Object, e As DevExpress.Web.Data.ASPxStartRowEditingEventArgs)
    If MyGridView.GetRowValuesByKeyValue(e.EditingKeyValue, "Department").ToString() <> UserDepartment Then
        e.Cancel = True
    End If
End Sub
