首先设置要显示图片的列
DataGridViewImageColumn status = new DataGridViewImageColumn();
status.DisplayIndex = ;
status.HeaderText = "Status";
status.DataPropertyName = "IsPass";
status.ImageLayout = DataGridViewImageCellLayout.Zoom;
dgvTestSteps.Columns.Insert(, status);
添加DataGridView事件CellFormatting
dgvTestSteps.CellFormatting += new DataGridViewCellFormattingEventHandler(dgvTestSteps_CellFormatting);
在事件内添加根据数据值显示不同图片的方法，判断列的地方有很多条件可以进行判断，但是通过Index感觉是最不可取的，通过HeadName也会有上下对不上的情况。
void dgvTestSteps_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (dgvTestSteps.Columns[e.ColumnIndex].HeaderText.Equals("Status"))
{
if (e.Value == null)
{
return;
}
StepType type = (StepType)Enum.Parse(typeof(StepType), e.Value.ToString(), true);
switch (type)
{
case StepType.Success:
e.Value = Resources.check;
break;
case StepType.Fail:
e.Value = Resources.close_delete;
break;
case StepType.Block:
e.Value = Resources.attention;
break;
case StepType.NoRun:
e.Value = Resources.green_ball;
break;
}
}
}
