C# 如何在导出前格式化GridView中的列以在excel中显示所有数字?
我正在尝试将GridView导出到Excel,我有一列包含一系列数字,如1245333325364。当我运行GridView查询时,我可以看到完整的数字,但当我导出到excel时,我看到的是该列上的1.00133E+12。我知道我可以让用户在excel中更改,但并不是所有文件都在导出后打开,他们只是将其直接保存到一个目录中。我真的希望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进行更改。我正在用C#执行导出操作,任何帮助都将不胜感激 我用于导出GridView的代码如下所示:C# 如何在导出前格式化GridView中的列以在excel中显示所有数字?,c#,gridview,C#,Gridview,我正在尝试将GridView导出到Excel,我有一列包含一系列数字,如1245333325364。当我运行GridView查询时,我可以看到完整的数字,但当我导出到excel时,我看到的是该列上的1.00133E+12。我知道我可以让用户在excel中更改,但并不是所有文件都在导出后打开,他们只是将其直接保存到一个目录中。我真的希望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进行更改。我正在用C#执行导出操作,任何帮助都将不胜感激 我用于导出GridView的代码如下所示: p

问题不在于单元格的宽度而不是格式吗?更改单元格的宽度,数字应该显示得很好。问题不在于单元格的宽度而不是格式吗?更改单元格的宽度,数字应该显示得很好。您可以将其单元格格式设置为数字
或货币
替换其原始格式。您可以将其单元格格式
设置为数字
或货币
替换其原始格式。尝试使用单个引号('))符号就在大数字之前。。。Excel将单引号识别为文本
或者,您可以尝试用双引号将值括起来,如“12345678901344”
希望这能奏效。试着在大数字前面加一个引号(')符号。。。Excel将单引号识别为文本
或者,您可以尝试用双引号将值括起来,如“12345678901344”
希望这能奏效。我终于找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,并在数据绑定上更加具体。请看下面的代码:
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");
}
}
然后在GridView上引用以下内容:
<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound">
就这些。我终于找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,并在数据绑定上更加具体。请看下面的代码:
