This method is called when the FormView control is not in insert mode.
-or-
The DataSourceView object associated with the FormView control is null. |
When the FormView control is in insert mode, use the InsertItem method to programmatically insert the current record in the data source. This method is commonly used when you need to insert the current record from outside of the FormView control, such as from a different control on the page.
NOTE: The FormView control must be in insert mode when this method is called; otherwise, an HttpException is thrown.
To specify whether page validation is performed before the insert operation, use the causesValidation parameter. Calling this method also raises the ItemInserted and ItemInserting events.
The following example demonstrates how to use the InsertItem method to programmatically insert the current record in a FormView control in the data source.
<%@ Page language = "C#" %>
<script runat = "server">
void InsertButton_Click ( Object src, EventArgs e ) {
try {
EmployeeFormView.InsertItem ( true );
MessageLabel.Text = "";
} catch ( HttpException ex ) {
MessageLabel.Text = "The FormView control must be in insert mode to insert a record.";
}
}
void CancelButton_Click ( Object src, EventArgs e ) {
// Return the FormView control to read-only mode.
EmployeeFormView.ChangeMode ( FormViewMode.ReadOnly );
MessageLabel.Text = "";
}
</script>
<%@ Page language = "VB" %>
<script runat = "server">
Sub InsertButton_Click ( ByVal src As Object, ByVal e As EventArgs )
Try
EmployeeFormView.InsertItem ( True )
MessageLabel.Text = ""
Catch ex As HttpException
MessageLabel.Text = "The FormView control must be in insert mode to insert a record."
End Try
End Sub
Sub CancelButton_Click ( ByVal src As Object, ByVal e As EventArgs )
' Return the FormView control to read-only mode.
EmployeeFormView.ChangeMode ( FormViewMode.ReadOnly )
MessageLabel.Text = ""
End Sub
