GridView空的处理
1 显示无表头的空纪录
EmptyDataText="没有记录"
2 显示表头的空纪录
DataTable dt = new DataTable(); dt = feibf.GetByPersonIDFollowExamInfo(PersonID); //查询指定人的随访信息记录 DataView dv = SortBindGrid(dt); if (dt.Rows.Count > 0) { FollowExamInfoGridView.DataSource = dv; FollowExamInfoGridView.DataBind(); } else { //添加新行显示表头 dt.Rows.Add(dt.NewRow()); FollowExamInfoGridView.DataSource = dt; FollowExamInfoGridView.DataBind(); //处理新行 int columnCount = FollowExamInfoGridView.Rows[0].Cells.Count; //清除掉该空行的全部单元格 FollowExamInfoGridView.Rows[0].Cells.Clear(); //新建单元格对象 FollowExamInfoGridView.Rows[0].Cells.Add(new TableCell()); //合并单元格 FollowExamInfoGridView.Rows[0].Cells[0].ColumnSpan = columnCount; //设置单元格提示内容 FollowExamInfoGridView.Rows[0].Cells[0].Style.Value = "text-align:center"; FollowExamInfoGridView.Rows[0].Cells[0].Text = "此人无随访信息"; }
GridView 的导出
EnableEventValidation="false"
#region导出
public override void VerifyRenderingInServerForm(Control control) { } protected void BtnPrint_Click(object sender, EventArgs e) { Response.Clear(); Response.Buffer = true; Response.Charset = "GB2312"; Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls"); // 如果设置为GetEncoding("GB2312");导出的文件将会出现乱码!!! Response.ContentEncoding = System.Text.Encoding.UTF7; Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); this.AfficheGV.RenderControl(oHtmlTextWriter); Response.Output.Write(oStringWriter.ToString()); Response.Flush(); Response.End(); } #endregion
ToolTip GridView详细信息的显示
前台
<script type="text/javascript" > function Tooltip(cella,cellb) { document.getElementById("dc").innerText = "详细信息:"+cellb; document.getElementById("id").innerText = "ID:"+cella; x= event.clientX+document.body.scrollLeft; y=event.clientY+document.body.scrollTop+20; toolTipLayer.style.display="inline"; toolTipLayer.style.left=x; toolTipLayer.style.top=y; } </script> <div id="toolTipLayer" style=" position:absolute; display:none; background-color:Aqua; border-color:Blue; border-style:solid; border-color:Blue; border-width:1px; " > <table> <tr><td>Affiche</td></tr> <tr><td id ="dc"></td></tr> <tr><td id ="id"> </td></tr> </table> </div>
后台
