我知道这有点太晚了，但我发布这篇文章只是为了提供信息。我在评论中找到了答案，但我仍然希望提交一个带有代码的答案，因为我自己发现很难找到代码，所以答案是针对您的网格是否在更新面板中的问题。您需要在按钮上添加后向触发器
private void RegisterPostBackControl()
{
ScriptManager.GetCurrent(this).RegisterPostBackControl(yourButton);
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}
protected void yourButton_Click(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", "full", true);
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=FormReport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
using (StringWriter sw = new StringWriter())
{
HtmlTextWriter hw = new HtmlTextWriter(sw);
//To Export all pages
yourGrid.AllowPaging = false;
var emps = FunctionThatGetsGridValues();
yourGrid.DataSource = emps;
yourGrid.DataBind();
yourGrid.HeaderRow.BackColor = Color.White;
foreach (TableCell cell in yourGrid.HeaderRow.Cells)
{
cell.BackColor = yourGrid.HeaderStyle.BackColor;
}
foreach (GridViewRow row in yourGrid.Rows)
{
row.BackColor = Color.White;
foreach (TableCell cell in row.Cells)
{
if (row.RowIndex % 2 == 0)
{
cell.BackColor = yourGrid.AlternatingRowStyle.BackColor;
}
else
{
cell.BackColor = yourGrid.RowStyle.BackColor;
}
cell.CssClass = "textmode";
}
}
yourGrid.RenderControl(hw);
//style to format numbers to string
string style = @"<style> .textmode { } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
yourGrid.Dispose();
}
}
如果这个解决方案对你有效，别忘了把它当作同一个问题的答案。我没有收到任何错误，但是弹出窗口没有出现，因此我无法保存excel文件。您是否在导出按钮的单击事件中使用该代码。是在单击事件方法中。我在您的代码（）中发现了这个问题，更正后的Response.End（）仍然不起作用。是，设置为false。
