Mode

Description

DetailsViewMode.Edit

The DetailsView control is in edit mode, which allows the user to update the values of a record.

DetailsViewMode.Insert

The DetailsView control is in insert mode, which allows the user to add a new record to the data source.

DetailsView.ReadOnly

The DetailsView control is in read-only mode, which is the normal display mode.

The following code example demonstrates how to use the ChangeMode method to return the DetailsView control to read-only mode whenever the user navigates to another record.


<%@ Page language="C#" %>

<script runat="server">

  void CustomerDetailView_PageIndexChanged(Object sender, EventArgs e)
  {
    // By default, if the DetailsView control is in edit mode and
    // user navigates to another page, the DetailsView control
    // remains in edit mode. In this example, the ChangeMode 
    // method is used to put the DetailsView control in read-only  
    // mode whenever the user navigates to another record.
      CustomerDetailView.ChangeMode(DetailsViewMode.ReadOnly);
  }

</script>
