This article mainly introduces "DataGridView how to set the prompt content of the cell ToolTip", in the daily operation, I believe that many people have doubts on the question of how to set the prompt content of the cell ToolTip in DataGridView. The editor consulted all kinds of materials and sorted out a simple and easy-to-use method of operation. I hope it will be helpful for everyone to answer the question of "how to set the prompt content of the cell in DataGridView". Next, please follow the editor to study!

The ToolTip property is used to set the prompt when the mouse moves over the cell.

In the case of DataGridView.ShowCellToolTips=True, the ToolTip of the cell can be expressed. For cells that are narrow and cannot be fully displayed, ToolTip can display the necessary information.

Example 1: set the ToolTip content of a cell

/ / set the prompt content of the first column in the second row this.dgv_PropDemo [0,1] .ToolTipText = "the contents of this cell cannot be modified"

Running effect:

Example 2: set the ToolTip content of the cell in the column header:

/ / set the ToolTipthis.dgv_PropDemo.Columns [3] .ToolTipText of the fourth column header = "only male or female can be entered in this row"

Running effect:

Example 3: set the ToopTip content of the cell in the header:

/ / set the ToopTipthis.dgv_PropDemo.Rows [0] .HeaderCell.ToolTipText of the first line header = "the contents of this row cell cannot be modified"

Running effect:

CellToopTipTextNeeded event

When setting the ToolTip of a batch of cells, it is relatively inefficient to specify one by one, so you can take advantage of the CellToopTipTextNeeded event. This event is also raised when the ToopTipText of a cell changes. However, when the DataSource of the DataGridView is specified and VirualMode=True, the event is not raised.

Private void dgv_PropDemo_CellToolTipTextNeeded (object sender, DataGridViewCellToolTipTextNeededEventArgs e) {/ / Mouse displays the prompt message if (e.ColumnIndex = = 2) {e.ToolTipText = "column:" + e.ColumnIndex.ToString () + ", row:" + e.RowIndex.ToString ();}} when the mouse is over the cell in the third column.

Running effect:
