步骤:
一、导入状态图片到项目中:
二、在窗体中声明一个图片数组,并在窗体的OnLoad事件中加入图片资源:
/// <summary>
/// 存储状态图片序列,避免同一状态对图片重复读取引发闪烁。
/// </summary>
private Image[] StatusImgs;
private void FrmSer_Main_Load(object sender, EventArgs e)
{
StatusImgs = new Image[] { Resources.TaskNA, Resources.TaskPause, Resources.TaskRun, Resources.TaskStart, Resources.TaskStop, Resources.TaskTimer };
}
三、处理Datgridview的格式化事件:
private void DgvTaskList_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{ if (DgvTaskList.Rows[e.RowIndex].IsNewRow) return;
if (e.ColumnIndex != 0) return; string stas =OPString.NZ2Str(DgvTaskList.Rows[e.RowIndex].Cells["RunStatus"].Value);
if (string.IsNullOrEmpty(stas)) stas = "Timer";
try
{
DataGridViewImageCell tmpCell = (DataGridViewImageCell)DgvTaskList.Rows[e.RowIndex].Cells["StatusImg"]; switch (stas)
{
case "NA":
tmpCell.Value = StatusImgs[0];
tmpCell.ToolTipText = "闲置";
break;
case "Pause":
tmpCell.Value = StatusImgs[1];
tmpCell.ToolTipText = "暂停";
break;
case "Run":
tmpCell.Value = StatusImgs[2];
tmpCell.ToolTipText = "运行中";
break;
case "Start":
tmpCell.Value = StatusImgs[3];
tmpCell.ToolTipText = "解析中";
break;
case "Stop":
tmpCell.Value = StatusImgs[4];
tmpCell.ToolTipText = "任务终止";
break;
case "Timer":
tmpCell.Value = StatusImgs[5];
tmpCell.ToolTipText = "循检中";
break;
default:
tmpCell.ToolTipText = "循检中";
break;
}
}
catch (Exception)
{
}
}
这样,你就能得到一个没有闪烁的状态图片列了。
