Question

我有开发表达ASPxGridView。 gridview的列和数据将根据下拉值动态生成。

   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excel的导出按钮。我的问题是它只会将gridview的列名导出到excel sheey中。数据是空的。但是在gridview数据中显示。请帮我解决这个问题。

确保在使用ASPxGridViewExporter.Write ***方法之前绑定了ASPxGridView：

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

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

ASPxGridViewExporter不会导出数据
