[英]From gridview to excel export - How can I get excel what I see in the application?
[英]How can I format a column from a GridView before export to show all numbers in excel?
我正在尝试将GridView导出到Excel,并且有一列包含一系列数字,例如1245333325364。当我运行GridView的查询时,我可以看到完整的数字,但是当我导出到excel时,我看到的是1.00133E +该列上的12。 我知道我可以让用户在excel中更改此设置,但是导出后并非所有文件都被打开,他们只是将其直接保存到目录中。 我真的很想在导出过程中更改列的格式,而不是让用户在保存文件之前先进行更改。 我正在用C#进行导出,对您的帮助将不胜感激。
我用来导出GridView的代码如下:
protected void exporttoexcel_Click(object sender, EventArgs e)
{
string date = DateTime.Now.ToString("MM-dd-yyyy");
PrepareGridViewForExport(GridView1);
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=" + date + "_" + CHROUT.Text + "_Trailer_" + TRAILER.Text);
Response.Charset = "''";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.DataBind();
GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
GridView1.HeaderRow.Cells[0].Style.Add("width", "105px");
GridView1.HeaderRow.Cells[0].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[1].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[2].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[3].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[4].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[5].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[6].Style.Add("background-color", "#CCCCCC");
GridView1.HeaderRow.Cells[7].Style.Add("background-color", "#CCCCCC");
for (int i = 0; i < GridView1.Rows.Count; i++)
{
GridViewRow row = GridView1.Rows[i];
row.BackColor = System.Drawing.Color.White;
row.Attributes.Add("class", "texmode");
if (i % 2 != 0)
{
row.Cells[0].Style.Add("background-color", "#f0f0f0");
row.Cells[1].Style.Add("background-color", "#f0f0f0");
row.Cells[2].Style.Add("background-color", "#f0f0f0");
row.Cells[3].Style.Add("background-color", "#f0f0f0");
row.Cells[4].Style.Add("background-color", "#f0f0f0");
row.Cells[5].Style.Add("background-color", "#f0f0f0");
row.Cells[6].Style.Add("background-color", "#f0f0f0");
row.Cells[7].Style.Add("background-color", "#f0f0f0");
}
}
GridView1.RenderControl(hw);
//style to format numbers to string
string style = @"<style> .text { mso-number-format:\@; } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
我终于得到了这个问题的答案。 我基本上只需要在导出之前将格式添加到GridView中,并且在DataBound上更具体。 看一下下面的代码:
首先为OnRowDataBound创建一个事件
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[1].Attributes.Add("class", "text");
e.Row.Cells[2].Attributes.Add("class", "text");
}
}
然后像这样在GridView上引用它:
<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound">
然后,只需在导出GridView之前添加这一小段代码即可。
Response.Write(style);
就这样。
这样尝试
protected void btnExportToExcel_Click(object s, EventArgs e)
{
GridView gvExportExcel = new GridView();
gvExportExcel.ID = "ExportExcel";
gvExportExcel.AllowPaging = false;
gvExportExcel.DataSource = listOfData(Generic list);
gvExportExcel.DataBind();
for (int i = 0; i < gvExportExcel.Rows.Count; i++)
gvExportExcel.Rows[i].Cells[0].Attributes.Add("style", "mso-number-format:\\@");
Export("Test.xls", gvExportExcel);
}
private void Export(string fileName, GridView dgvExport)
{
try
{
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", fileName));
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "application/ms-excel";
Response.Charset = string.Empty;
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
dgvExport.RenderControl(htw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.ApplicationInstance.CompleteRequest();
HttpContext.Current.Response.Close();
//HttpContext.Current.Response.End();
}
catch (System.Threading.ThreadAbortException ex)
{
//write your exception
}
}
问题不是单元格的宽度之一,而不是格式吗? 更改单元格的宽度,数字应该可以正常显示。
您可以将其CellFormat
设置为Number
或Currency
替换其原始格式。
尝试在大数字之前放置一个单引号(')符号。Excel将单引号识别为文本。
或者,您可以尝试将值括在双引号中,例如“ 12345678901234”
希望这行得通。
