将 Gridview 导出到 Excel 时删除复选框 [英] Remove Checkboxes while exporting Gridview to Excel

问题描述

我有一个需要导出到 Excel 的 gridview.我设法从行中删除了复选框，但不知道如何从标题中删除并完全删除复选框列.感谢您的帮助.

I have a gridview that needs to be exported to Excel. I have managed to remove the Checkboxes from Rows but don't know how to remove from the Header and also delete the Checkbox Column entirely. Thanks for help.

    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="Id">
    <Columns>
        <asp:TemplateField HeaderText="Select" >
            <HeaderTemplate>
                <input id="chkAll" onclick="checkAll(this);" runat="server" type="checkbox" />
            </HeaderTemplate>
            <ItemTemplate>
            <asp:CheckBox  ID="CheckBox1" runat="server" />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="Event" HeaderText="Event" SortExpression="Event" />
        <asp:BoundField DataField="Event_Description" HeaderText="Event_Description" SortExpression="Event_Description" />
        <asp:BoundField DataField="Start_Date" HeaderText="Start_Date" SortExpression="Start_Date" />
    </Columns>
    </asp:GridView>

这是要导出到 excel 的后端 C# 代码.

Here's the backend C# code to export to excel.

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]);
        }
    }
}

推荐答案

试试这个导出功能，它隐藏不需要的列，即行的第 0 列...

Try out this export function , which hides not needed column i.e column 0 of the row...

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();
}

或

在导出时，删除该列.类似的东西:

On your export, drop the column. Something something like:

GridView1.Columns[0].visible = false;
 GridView1.DataBind();
  GridView1.RenderControl(htmlWrite);
 Response.Write("<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />");
