Initialize a toolstripitem in Windows Forms Applications

The user can initialize a toolstripitem very easily with LinsUI Layout Manager 2.1.

The following example demonstrates how to specify and code the handler for the INITIALIZE event of a Dropdown control

First define a unique ID for m_nColorsDropDownID in LinsResource class as following,

using LinsUI;

public static class LinsResource

{

 // The Category name

[CommandGroupNameAttribute("Colors"),              

 // Tell the application, it is a dropdown button

 CommandTypeAttribute(TSITEM_TYPEID.DROPDOWNBUTTON),  

 // Tooltip for the menu item  

 ToolTipAttribute("Select a color"),   

 // The detail description           

 DetailDescriptionAttribute("Select a color for the selected shapes.")]    

public const long m_nColorsDropDownID = FlexConstants.m_nUserDefinedControlStartID + 5;

}

Then assign the unique ID to the tag of the menu item, and define the handler function for the INITIALIZE event as following,

public partial class ColorsMenu : LinsUI.LinsMenuStrip

{

private ToolStripMenuItem m_Colors;

public ColorsMenu()

{

InitializeComponent();

m_Colors = new ToolStripMenuItem();

// Assign an unique ID to the m_Colors menu dropdown item

m_Colors.Tag = LinsResource.m_nColorsDropDownID;

 }

// define the handler function for the INITIALIZE event

// when the Color dropdown is created, this event will be fired and only fired once.

// The user can use this event to do initialization

[CommandIDAttribute(LinsResource.m_nColorsDropDownID),

// The event type, here is an initialize event    

 CommandEventAttribute(CUSTOM_TI_EVENT.INITIALIZE)]

void ColorsInitialize(object sender, System.EventArgs e)

{

// Add all possible colors into the Color dropdown list

foreach (Color_Name pair in DemoManager.m_lsColorName)

{

this.m_Colors.DropDownItems.Add(pair.m_csName);

}

}

}
