我有一个“下载”按钮，可以创建一个 excel 文件然后打开它。它在 Firefox 中运行良好，但在 IE 中单击该按钮完全没有任何作用。有谁知道为什么或如何解决它？这是代码：
<div align="center" id="excelDiv" runat="server">
<a id="excelDownloadLink" runat="server">
<input type="button" id="btnSubmitDownload" value="Download" />
</a>
<br /><br />
<span id="validationResults" style="color:Red"></span><br />
</div>
后面的代码：
protected void Page_Load(object sender, EventArgs e)
{
excelDownloadLink.ServerClick += new System.EventHandler(ExcelDownload);
DataCounts.DataSource = db.GetRequestCountByState();
DataCounts.DataBind();
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Confirms that an HtmlForm control is rendered for the specified ASP.NET
server control at run time. */
}
public void ExcelDownload(object sender, EventArgs e)
{
DateTime startDateVal = DateTime.Parse(startDate.Value.ToString());
DateTime endDateVal = DateTime.Parse(endDate.Value.ToString());
if (searchType.Value == "Requests by Status")
{
DataSet statusExtract = db.GetStatusExport(startDateVal, endDateVal);
DataTable statusExtractTable = statusExtract.Tables[0];
DumpExcel(statusExtractTable, "Requests by Status");
}
else if (searchType.Value == "Database Extract")
{
DataSet dataExtract = db.GetDataExport(startDateVal, endDateVal);
DataTable dataExtractTable = dataExtract.Tables[0];
DumpExcel(dataExtractTable, "Database Extract");
}
}
private void DumpExcel(DataTable tbl, string type)
{
using (ExcelPackage pck = new ExcelPackage())
{
//Create the worksheet
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Database Extract");
//Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
