Description: The attached code demonstrates a technique you can use to create multiline balloon tooltips for ListView items.The code is based on the following simple idea. In the MouseMove event you need to check the index of the item under the mouse pointer, and if this item is changed, you simply redefine the text of the tooltip attached to the ListView control. Notice that you should destroy the tooltip if there is no any item under the mouse pointer.To determine the index of the list-view item under the mouse pointer, we send the LVM_HITTEST message to the ListView control. The SendMessage function you should use to send this message returns the index of the item at the specified position, if any, or -1 otherwise. Before you send the message, populate the pt field of an instance of the LVHITTESTINFO structure with the coordinates of the mouse pointer (you pass the reference to this structure as the value of the lParam parameter in SendMessage). You can use for this purpose the X and Y parameters of the MouseMove event of the control, but draw attention at the fact that these parameters can be measured in twips and you need to convert them in pixels.This simple idea can be used to create such tooltips for ListBox items, any grid control items and so on. For instance, we use this technique in extra samples for iGrid ActiveX Control we produce (this is an editable replacement for ListView and FlexGrid

大家知道 TreeView 上的节点如果显示不完全，鼠标移上去会出现一提示，这就是 In-place Tooltips。下面这段代码在 Listbox 上实现这一功能(下面代码只是在标准 Listbox 上测试，如果是自画的，则要修改)：{直接将下面代码拷贝到新建工程中Form1的Unit1.pas文件即可运行，不需添加任何控件}//--------------------------

几乎所有的WebForm控件都具有的属性 1.ClientID，获取控件在客户端的ID。 2.Visible 属性，判断控件是否可见。如果控件的visible的属性设为False的话不仅调试的时候看不到该控件，在源文件一样看不到。 3.CssClass 属性，控件的样式名，就是HTML中控件的class属性。可以直接在控件的属性栏里修改CssClass的属性为你想要的css样式。当然那个样式
