我有开发快递 ASPxGridView。gridview 的列和数据将根据下拉值动态变化。

   If type = "procedure" Then
        SqlDataSource2.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
    Else
        SqlDataSource2.SelectCommandType = SqlDataSourceCommandType.Text
    End If

    SqlDataSource2.SelectCommand = rptquery

    Try
        SqlDataSource2.DataBind()
        dataview1 = SqlDataSource2.Select(System.Web.UI.DataSourceSelectArguments.Empty)
        gv.DataSourceID = "SqlDataSource2"
        For Each dc In dataview1.Table.Columns
            Dim DynamicColumn = New DevExpress.Web.ASPxGridView.GridViewDataTextColumn()
            DynamicColumn.FieldName = dc.ColumnName
            DynamicColumn.Caption = dc.ColumnName

            gv.Columns.Insert(i, DynamicColumn)
            i = i + 1

        Next
        gv.DataBind()

    Catch ex As Exception

    End Try

然后我有导出按钮到excel。我的问题是它只会将gridview的列名导出到excel sheey中。数据为空。但在 gridview 中显示数据。请在这个问题上帮助我。

确保在使用 ASPxGridViewExporter.Write*** 方法之前已绑定 ASPxGridView：

'SqlDataSource2.DataBind()
'dataview1 = SqlDataSource2.Select(System.Web.UI.DataSourceSelectArguments.Empty)

ASPxGridViewExporterInstance.GridView = gv
gv.DataSource = SqlDataSource2
ASPxGridViewExporterInstance.Write***
