C# 将Gridview导出到Excel:无法导出显示的正确数据
我需要将gridview数据导出到excel。这没问题。 一切正常 问题是我可以对网格中显示的数据应用过滤器。当我只想导出这些数据时(一旦应用了过滤器),它会导出过滤器之前网格中包含的所有数据 我希望我足够清楚 这是我正在使用的代码:C# 将Gridview导出到Excel:无法导出显示的正确数据,c#,.net,export-to-excel,C#,.net,Export To Excel,我需要将gridview数据导出到excel。这没问题。 一切正常 问题是我可以对网格中显示的数据应用过滤器。当我只想导出这些数据时(一旦应用了过滤器),它会导出过滤器之前网格中包含的所有数据 我希望我足够清楚 这是我正在使用的代码: public void ExportGridToExcel(GridView grdGridView, string fileName) { Response.Clear(); Response.Buffer = t

对于(int i=0;i
我如何应用过滤器(所有操作都很完美)
public void refreshGridFactures()
{
DateTime?debutFacture=null;
DateTime?FinFacture=null;
DateTime?debutreement=null;
DateTime?FinRegElement=null;
int?字符数=0;
如果(PickerDateDefinition.SelectedDate!=null){debutFacture=PickerDateDefinition.SelectedDate;}
如果(PickerDateFin.SelectedDate!=null){FinFacture=PickerDateFin.SelectedDate;}
如果(pickerdebutregelement.SelectedDate!=null){debtreglement=pickerdebutregelement.SelectedDate;}
如果(PickerFinRegElement.SelectedDate!=null){FinRegElement=PickerFinRegElement.SelectedDate;}
int identireprise=Convert.ToInt32(ddlEnterprises.SelectedValue);
字符串Intitule=txtinitule.Text;
if(txtNumeroFacture.Text!=“”){NumeroFacture=Convert.ToInt32(txtNumeroFacture.Text);}
List ListFactoration=DBAccess.DaoFactoration.GetFactories(识别、去特征、去特征、去特征、去特征、去特征、去特征、去特征、去特征、去特征);
GridFactures.DataSource=列表制作;
gridfactes.DataBind();
双倍合计=数学四舍五入(listfacturion.Sum(a=>a.montanttc),2);
double totalHT=数学圆(listfacturion.Sum(a=>a.MontantHT),2);
lbltottalttc.Text=“Montant total TTC:+总计;
lblTotalHT.Text=“Montant total HT:+totalHT;
}
感谢您的帮助就在您的
gridview行=grdGridView.Rows[i]代码>添加检查以查看行是否可见
如果(!row.Visible)继续代码>实际上您正在导出为HTML,因为grdGridView.RenderControl(hw)
将创建一个表;-)
