将Gridview导出到Excel时删除复选框

我有一个需要导出到Excel的gridview。 我已设法从行中删除Checkboxes但不知道如何从标题中删除并完全删除Checkbox列。 感谢帮助。

这是导出到excel的后端C＃代码。

 protected void download_Click(object sender, EventArgs e) { PrepareGridViewForExport(GridView1); Response.ClearContent(); Response.AddHeader("content-disposition", "attachment; filename=GridViewToExcel.xls"); Response.ContentType = "application/excel"; StringWriter sWriter = new StringWriter(); HtmlTextWriter hTextWriter = new HtmlTextWriter(sWriter); GridView1.RenderControl(hTextWriter); Response.Write(sWriter.ToString()); Response.End(); } public override void VerifyRenderingInServerForm(Control control) { } private void PrepareGridViewForExport(Control gv) { Literal l = new Literal(); string name = String.Empty; for (int i = 0; i < gv.Controls.Count; i++) { if (gv.Controls[i].GetType() == typeof(CheckBox)) { gv.Controls.Remove(gv.Controls[i]); gv.Controls.AddAt(i, l); } if (gv.Controls[i].HasControls()) { PrepareGridViewForExport(gv.Controls[i]); } } }

试试这个导出函数，它隐藏了不需要的列，即行的第0列……

 protected void btnExportExcel_Click(object sender, EventArgs e) { Response.Clear(); Response.Buffer = true; Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls"); Response.Charset = ""; Response.ContentType = "application/vnd.ms-excel"; StringWriter sw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(sw); GridView1.DataBind(); GridView1.HeaderRow.Cells[0].Visible = false; for (int i = 0; i < GridView1.Rows.Count;i++ ) { GridViewRow row = GridView1.Rows[i]; row.Cells[0].Visible = false; row.Cells[0].FindControl("chkCol0").Visible = false; } GridView1.RenderControl(hw); Response.Write(style); Response.Output.Write(sw.ToString()); Response.End(); } 

要么

在导出时，删除列。 类似的东西：

 GridView1.Columns[0].visible = false; GridView1.DataBind(); GridView1.RenderControl(htmlWrite); Response.Write("");

我们可以在导出到Excel之前删除它们，而不是隐藏控件。
这可以通过循环遍历细胞并找到细胞中存在的对照来完成。 然后识别控件类型并从该单元格中删除它们。

以下是代码：

 foreach (GridViewRow row in GridView1.Rows) { row.BackColor = Color.White; foreach (TableCell cell in row.Cells) { cell.CssClass = "textmode"; for (int i = 0; i < cell.Controls.Count; i++) { Control ctr = cell.Controls[i]; if (ctr is TextBox) cell.Controls.Remove(ctr); else if (ctr is DropDownList) cell.Controls.Remove(ctr); else if (ctr is Label) { if (ctr.ClientID.Contains("lblrow")) cell.Controls.Remove(ctr); } } } } 

在上面的代码中，我循环遍历每一行和单元格。 然后删除所有TextBox，DropdownList和Label ，其中包含ID lblrow 。
