今天用到了gridcontrol这个控件,要求写一个gridview的双击事件,因为想要的效果是只双击行才出Message,用gridview的Double_Click我没实现,后来想到MouseDown,一试,很简单,首先,仍旧需要将gridview1.OptionsBehavior.Editable设为false,下面是代码:
//双击行弹出nodeDetail信息
private void gridView1_MouseDown(object sender, MouseEventArgs e) { DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hInfo = gridView1.CalcHitInfo(new Point(e.X,e.Y)); if (e.Button == MouseButtons.Left && e.Clicks == 2) { //判?断?光?标?是?否?在?行?范?围?内? if (hInfo.InRow) { //取?得?选?定?行?信?息? string nodeName = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "nodeName").ToString(); //string nodeName = gridView1.GetRowCellValue(gridView1.GetSelectedRows()[0], "nodeName").ToString(); string sql = "select nodeDetail from treelist where nodeName = '" + nodeName + "'"; SqlCommand comm = new SqlCommand(sql, conn); try { conn.Open(); MessageBox.Show(comm.ExecuteScalar().ToString(), "Detail"); } catch (Exception ex) { MessageBox.Show(ex.Message, "Error"); } finally { conn.Close(); } } } }
