ToolTip Support in Windows Forms TreeMap control

17 Feb 20251 minute to read

Tooltip shows additional information on the tree map control. Visibility of tooltip can be controlled using the IsToolTipVisible property. The format of the tooltip header and item can be customized using the HeaderToolTipInfo and ItemToolTipInfo properties.

Code sample

C#
ToolTipInfo itemInfoHead = new ToolTipInfo();

itemInfoHead.ToolTipHeaderPattern = "&lt;b&gt;{Label}&lt;/b&gt;";

itemInfoHead.ToolTipContentPattern = "Growth \t  :  {Growth} % ";

TreeMap1.HeaderToolTipInfo = itemInfoHead;

ToolTipInfo itemInfo = new ToolTipInfo();

itemInfo.ToolTipHeaderPattern = "&lt;b&gt;{Country}&lt;/b&gt;";

itemInfo.ToolTipContentPattern = "Growth \t      :  {Growth} %  \nPopulation   :  {StrPopulation}  ";

TreeMap1.ItemToolTipInfo = itemInfo;
