将GridView导出到Excel，而不使用超链接显示为红色的gridview单元格

我有一个ASP.Net 4.0 GridView和一个将GridView数据导出到Excel的button。 这一切工作正常。 但是，在GridView中，每行的三个单元格中的文本都是红色的，因为它们是超链接。 当我将数据导出到Excel时，这些单元格仍然是红色的。 我希望他们是黑色的。 我该怎么做呢？ 这是我的代码：

Response.ClearContent(); Response.AppendHeader("content-disposition", "attachment; filename=Mobile.xls"); Response.ContentType = "application/excel"; StringWriter stringWriter = new StringWriter(); HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter); foreach (GridViewRow gridViewRow in gvResults.Rows) { gridViewRow.ForeColor = Color.Black; foreach (TableCell gridViewRowTableCell in gridViewRow.Cells) gridViewRowTableCell.Style["forecolor"] = "#000000"; if (gridViewRow.RowType == DataControlRowType.DataRow) { for (int columnIndex = 0; columnIndex < gridViewRow.Cells.Count; columnIndex++) { gridViewRow.Cells[columnIndex].Attributes.Add("class", "text"); } } } gvResults.RenderControl(htmlTextWriter); string style = @"<style> .text { mso-number-format:\@; } </style> "; Response.Write(style); Response.Write(stringWriter.ToString()); Response.End(); 

这里是链接的代码。 这运行OnDataBound：

 foreach (GridViewRow row in gvResults.Rows) { if (row.RowType == DataControlRowType.DataRow || row.RowType == DataControlRowType.EmptyDataRow) { string imei = row.Cells[0].Text; if (imei != "&nbsp;") { string imeiLink = "window.location='SmartphoneInventory.aspx?imei=" + imei + "';"; row.Cells[0].Attributes.Add("onClick", String.Format(imeiLink)); row.Cells[0].Text = "<span style='color:red'>" + row.Cells[0].Text + "</span>"; } string phonenumber = row.Cells[1].Text; if (phonenumber != "&nbsp;") { string phonenumberLink = "window.location='SmartphoneInventory.aspx?phonenumber=" + phonenumber + "';"; row.Cells[1].Attributes.Add("onClick", String.Format(phonenumberLink)); row.Cells[1].Text = "<span style='color:red'>" + row.Cells[1].Text + "</span>"; } int cellCount = row.Cells.Count; string empName = row.Cells[cellCount - 1].Text; if (empName != "&nbsp;") { string empNameLink = "window.location='DevicesByEmployee.aspx?empName=" + empName + "';"; row.Cells[cellCount - 1].Attributes.Add("onClick", String.Format(empNameLink)); row.Cells[cellCount - 1].Text = "<span style='color:red'>" + row.Cells[cellCount - 1].Text + "</span>"; } } } 

我想我需要的是如何重新devise跨度。 这可能吗？ GridView自动生成其列。

获取LinkBut​​ton文本，将其分配给GridView单元格文本和删除控件。

这是我在标题中做的：

C＃

 foreach (TableCell c in gv.HeaderRow.Cells) { if (c.HasControls) { c.Text = (c.Controls(0) as LinkButton).Text; c.Controls.Clear(); } } 

VB.NET

 For Each c As TableCell In gv.HeaderRow.Cells If c.HasControls Then c.Text = TryCast(c.Controls(0), LinkButton).Text c.Controls.Clear() End If Next 

编辑：

创build一个扩展方法：

C＃

 [Extension()] public string StripTags(string html) { return Regex.Replace(html, "<.*?>", ""); } 

VB.NET

 <Extension> _ Public Function StripTags(html As String) As String Return Regex.Replace(html, "<.*?>", "") End Function 

它会从你的string中删除标签，因此你的风格。 使用方法如下：

  foreach (GridViewRow gridViewRow in gvResults.Rows) { gridViewRow.ForeColor = Color.Black; foreach (TableCell gridViewRowTableCell in gridViewRow.Cells) gridViewRowTableCell.Style["forecolor"] = "#000000"; if (gridViewRow.RowType == DataControlRowType.DataRow) { for (int columnIndex = 0; columnIndex < gridViewRow.Cells.Count; columnIndex++) { gridViewRow.Cells[columnIndex].Text = gridViewRow.Cells[columnIndex].Text.StripTags(); } } }
