HtmlElementErrorEventArgs.LineNumber Property

Gets the line of HTML script code on which the error occurred.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int LineNumber { get; }

Property Value

Type: System.Int32
An Int32 designating the script line number.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the HtmlWindow.Error event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type HtmlWindow named HtmlWindow1. Then ensure that the event handler is associated with the HtmlWindow.Error event.


private void HtmlWindow1_Error(Object sender, HtmlElementErrorEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Description", e.Description );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "LineNumber", e.LineNumber );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Url", e.Url );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Error Event" );
}
