To add ToolTips that display UserData for a cell range, use C1FlexGrid's MouseMove event to get the CellRange.UserData property and display it in a ToolTip control.

1. Locate the ToolTip control in the Toolbox and add it to the form.
2. In the Form_Load event, set the UserData property for a cell range that contains a group of non-metallic elements:

   To write code in Visual Basic

   Visual Basic	Copy Code
   ' Set the cell range that contains the non-metallic elements. Dim rng As C1.Win.C1FlexGrid.CellRange = Me.C1FlexGrid1.GetCellRange(6, 1, 10, 10) ' Set the background color to see the cell range more easily. rng.StyleNew.BackColor = Color.AliceBlue ' Set the user data for the cell range. rng.UserData = "Non-Metallic"

   To write code in C#

   C#	Copy Code
   // Set the cell range that contains the non-metallic elements. C1.Win.C1FlexGrid.CellRange rng = this.c1FlexGrid1.GetCellRange(6, 1, 10, 10); // Set the background color to see the cell range more easily. rng.StyleNew.BackColor = Color.AliceBlue; // Set the user data for the cell range. rng.UserData = "Non-Metallic";

3. Add the following MouseMove event:

   Visual Basic	Copy Code
   Private Sub C1FlexGrid1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles C1FlexGrid1.MouseMove Dim tip As String tip = Me.C1FlexGrid1.GetUserData(C1FlexGrid1.MouseRow, C1FlexGrid1.MouseCol) ToolTip1.SetToolTip(C1FlexGrid1, tip) End Sub

   To write code in C#

   C#	Copy Code
   private void c1FlexGrid1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e) { string tip; tip = (string)this.c1FlexGrid1.GetUserData(c1FlexGrid1.MouseRow, c1FlexGrid1.MouseCol); toolTip1.SetToolTip(c1FlexGrid1, tip); }

This topic illustrates the following:

The ToolTip appears within the entire cell range.
