问题描述
我无法使用自定义数据源将 aspxgridview 对象中的内容传输到 excel。只有页眉和页脚即将到来。 我已经分享了我的所有代码，以便您完全了解情节。 无关紧要，当使用下拉列表选择该项目时，我的数据将被重塑。

解决方法
在我的页面添加gridviewexporter和button后，button点击事件； 默认.aspx
<asp:Button runat="server" ID="aktar" OnClick="aktar_OnClick" Text="aktar"/>
<dx:ASPxGridViewExporter ID="ASPxGridViewExporter1" runat="server" GridViewID="dev" >
</dx:ASPxGridViewExporter>
default.aspx.cs 页面
protected void aktar_OnClick(object sender,EventArgs e)
{
Datalist();
ASPxGridViewExporter1.WriteXlsxToResponse(new XlsxExportOptionsEx { ExportType = ExportType.WYSIWYG });
}
我的问题解决了。希望它有益于您的业务
