为 DataGridView 设置 ToolTip 自动创建的列 [英] Setting ToolTip for DataGridView automatically created columns

问题描述

我想以编程方式将工具提示设置为在 DataGridView 中自动生成的列.我试图使用 AutoGeneratingColumn 事件 (http://msdn.microsoft.com/en-us/library/cc903950%28VS.95%29.aspx)，但实际上只能访问DataGridColumn，不能DataGridViewColumn，前者没有 ToolTipText 属性.

I would like to programatically set tooltips to automatically generated columns in a DataGridView. I was trying to use AutoGeneratingColumn event (http://msdn.microsoft.com/en-us/library/cc903950%28VS.95%29.aspx), but that in fact can only access DataGridColumn, not DataGridViewColumn, and the former doesn't have ToolTipText property.

或者，如果我可以将工具提示绑定到一个也很棒的源.目标是能够在我为基础 DataTable 设置列的同一位置操作/设置工具提示.

Or if I could bind the ToolTips to a source that would also be great. The goal is to have the ability to manipulate/set tooltips in the same place where I set the columns for the underlying DataTable.

推荐答案

我是这样解决的:

void payloadDataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    string tooltip = null;

    switch (e.Column.Header.ToString())
    {
        case "Column 1":
            tooltip = "Tooltip 1";
            break;
        case "Column 2":
            tooltip = "Tooltip 2";
            break;
    }

    if (tooltip != null)
    {
        var style = new Style(typeof(DataGridCell));
        style.Setters.Add(new Setter(ToolTipService.ToolTipProperty, tooltip));
        e.Column.CellStyle = style;
    }
}
