winforms工具提示在winforms DataGridViewImageColumn [英] winforms Tooltip in winforms DataGridViewImageColumn

问题描述

我有以下代码根据其绑定的DataProperty在其列中成功显示一个图像：

I have the following code that successfully displays an image in its column based on its bound DataProperty:

  private void dgvTasks_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e ) {
        if (dgvTasks.Columns[e.ColumnIndex] is DataGridViewImageColumn && e.ColumnIndex == 1) {
            e.Value = ( (bool)e.Value == true ) ? Properties.Resources.ok : Properties.Resources.clock;
        }
  }

但我想知道如何显示一个用户徘徊在图像上的工具提示？

but I would like to know how its possible to show a tooltip when a user hovers over the image?

推荐答案

一般来说，如果你有行&列可以使用以下方式设置ToolTipText：

generally if you have row & column for a cell, you can set a ToolTipText using:

dataGridView1.Rows[rowIndex].Cells[columnIndex].ToolTipText = "..."

在你的情况下，你有e.RowIndex和e.RowIndex： / p>

and in your case, you have e.RowIndex and e.RowIndex:

dgvTasks.Rows[e.RowIndex].Cells[e.ColumnIndex].ToolTipText = "..."
