![]() Computes the layout of the item's image and text. This method defines the painting behavior of the control. Protected override void OnMouseLeave(EventArgs e) It sets the state of the rolloverValue field to false and This method defines the behavior of the MouseLeave event. Protected override void OnMouseEnter(EventArgs e) It sets the state of the rolloverValue field to true and This method defines the behavior of the MouseEnter event. String msg = String.Format("Item: ", this.Text) Protected override void OnDoubleClick(EventArgs e) It shows a MessageBox with the item's text. The method defines the behavior of the DoubleClick Protected override void OnClick(EventArgs e) It simply toggles the state of the clickedValue field. The method defines the behavior of the Click event. has been toggled into the clicked state. This property returns true if the item ![]() This property returns true if the mouse is Value = TextImageRelation.TextBeforeImage) If (value = TextImageRelation.ImageBeforeText || Public new TextImageRelation TextImageRelation TextImageRelation values to ImageBeforeText and TextBeforeImage. "RolloverItem supports only horizontal text.") If (value = ToolStripTextDirection.Horizontal) Public override ToolStripTextDirection TextDirection TextDirection values to ToolStripTextDirection.Horizontal. For brevity, this implementation limits the possible Public class RolloverItem : ToolStripItem by highlighting or graying out the item's image. exposed through the Clicked property and displayed its border and text when the mouse enters its This class implements a ToolStripItem that highlights ![]() The following code example demonstrates how to implement a custom ToolStripItem control. IComponent IDisposable IDropTarget Examples Implements IDisposable, IDropTarget Inheritance Implements IDisposable, IDropTarget Public MustInherit Class ToolStripItem Interface IDisposable Public MustInherit Class ToolStripItem Interface IDisposable type ToolStripItem = class public ref class ToolStripItem abstract : System::ComponentModel::Component, IDisposable, System::Windows::Forms::IDropTarget public ref class ToolStripItem abstract : System::Windows::Forms::BindableComponent, IDisposable, System::Windows::Forms::IDropTarget public abstract class ToolStripItem :, IDisposable, public abstract class ToolStripItem :, IDisposable, type ToolStripItem = class You can also create an EventHandler for the 'FormClosing Event of the LogIn form, and in that code get more detailed information about exactly why the LogIn form is being closed by accessing the 'CloseReason enumeration in the event-arguments for that event-handler.Represents the abstract base class that manages events and layout for all the elements that a ToolStrip or ToolStripDropDown can contain. }There is another way to do this, which I prefer to use, where you start the Application with an 'ApplicationContext instance, but I think this example is simpler, and more appropriate, in this context. your validation function that returns a 'bool // goes here // ? Private bool LogInValidator( string password, string username) what now ? cancel ? // allow the user to repeat again for #n times ? // do "nothing" here and the Application will terminate If (LogInValidator(tbxPassword.Text, tbxUserName.Text)) Private void btnSubmit_Click( object sender, EventArgs e) Private void btnCancel_Click( object sender, EventArgs e)
