I have a page with gridview. 我有一个带有gridview的页面。 I need to download that gridview data in the excel format.
我需要以excel格式下载该gridview数据。 I have used the following code to download into the excel format.
我已使用以下代码下载到excel格式。
public static void Export(string fileName, GridView gv)
{
string style = @"<style> .text { mso-number-format:\@;text-align:right; } </style> ";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", fileName));
HttpContext.Current.Response.ContentType = "application/ms-excel";
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
HttpContext.Current.Response.Write(style);
// Create a table to contain the grid
System.Web.UI.WebControls.Table table = new System.Web.UI.WebControls.Table();
// include the gridline settings
table.GridLines = gv.GridLines;
// add the header row to the table
if (gv.HeaderRow != null)
{
PrepareControlForExport(gv.HeaderRow);
table.Rows.Add(gv.HeaderRow);
}
// add each of the data rows to the table
foreach (GridViewRow row in gv.Rows)
{
// add numeric style for each cell
foreach (TableCell cell in row.Cells)
{
cell.Attributes.Add("class", "text");
}
PrepareControlForExport(row);
table.Rows.Add(row);
}
// add the footer row to the table
if (gv.FooterRow != null)
{
PrepareControlForExport(gv.FooterRow);
table.Rows.Add(gv.FooterRow);
}
// render the table into the htmlwriter
table.RenderControl(htw);
// render the htmlwriter into the response
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.ApplicationInstance.CompleteRequest();
}
}
}
/// <summary>
/// Replace any of the contained controls with literals
/// </summary>
/// <param name="control"></param>
private static void PrepareControlForExport(Control control)
{
for (int i = 0; i < control.Controls.Count; i++)
{
Control current = control.Controls[i];
if (current is LinkButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));
}
else if (current is ImageButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as ImageButton).AlternateText));
}
else if (current is HyperLink)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as HyperLink).Text));
}
else if (current is DropDownList)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as DropDownList).SelectedItem.Text));
}
else if (current is CheckBox)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));
}
if (current.HasControls())
{
PrepareControlForExport(current);
}
}
}
As soon as download the file it is download the css files of the master page also. 一旦下载文件,它也将下载母版页的css文件。 Can you please let me know, how to resolve this.
您能告诉我如何解决此问题吗?
try my working method: 试试我的工作方法:
void ExportToExcel(GridView grdData, string filename)
{
grdData.BorderStyle = BorderStyle.Solid;
grdData.BorderWidth = 1;
grdData.BackColor = Color.WhiteSmoke;
grdData.GridLines = GridLines.Both;
grdData.Font.Name = "Verdana";
grdData.Font.Size = FontUnit.XXSmall;
grdData.HeaderStyle.BackColor = Color.DimGray;
grdData.HeaderStyle.ForeColor = Color.White;
grdData.RowStyle.HorizontalAlign = HorizontalAlign.Left;
grdData.RowStyle.VerticalAlign = VerticalAlign.Top;
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.Charset = "";
response.ContentType = "application/vnd.ms-excel";
response.AddHeader("Content-Disposition", "attachment;filename=\"" + filename+ "\"");
using (var sw = new StringWriter())
{
using (var htw = new HtmlTextWriter(sw))
{
grdData.RenderControl(htw);
response.Write(sw.ToString());
response.End();
}
}
}
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "excelname.xls"));
Response.ContentType = "application/ms-excel";
//which row you dont want in gridview
GridView5.Columns[0].Visible = false;
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
GridView5.AllowPaging = false;
GridView5.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
