Hello,

The issue may occur when the ASPxGridView is bound at runtime, and the grid doesn't have the datasource at the moment of binding. I see that you're using ASPxComboBox with server-side events. It may force building ASPxGridView hierarchy earlier than the DataSource property is assigned (ASPxGridView isn't bound yet). To resolve this issue, the DataSource property is defined on each round trip to the server either in the Page.Init event handler or in the ASPxGridView.DataBinding event handler (see Why might paging (sorting, grouping, filtering) not work in the ASPxGridView?). I suggest you move the code where you're setting the grid's DataSource property from the Page_Load to the Page_Init event handler and check if this helps.
If this approach doesn't help, provide us with a sample runnable project where we can reproduce this behavior in action.

      Thank you for your effort
      and your suggestion (Page_Init) working with me but when bound another field it returns the same error

      ASPx
      <dx:GridViewDataSpinEditColumn Width="10%" FieldName="Trans_ItemPrice" ReadOnly="true" Caption="التكلفة">  
                                            <EditItemTemplate>  
                                                <dx:ASPxSpinEdit ID="Cat2" ReadOnly="true" Number='<%# Bind("Trans_ItemPrice") %>' Theme="MaterialCompact" runat="server">  
                                                </dx:ASPxSpinEdit>  
                                            </EditItemTemplate>  
                                        </dx:GridViewDataSpinEditColumn>

        Hi,

        Unfortunately, it's hard to determine the cause of the problem without inspecting your code. Typically, such errors occur when the underlying data set does not have a corresponding field that is used by the control (e.g., this error occurs when you switch data sources or the select query is changed). I suggest you try recommendations from the Q246426: WebDataRow does not contain a property with the name and T266763: ASPxGridView - The " 'DevExpress.Web.Data.WebDataRow' does not contain a property with the name 'X' " exception is thrown in certain casestickets, where we have answered a similar question.
        I also recommend you refer to the Q534489: ASPxGridView - 'DevExpress.Web.Data.WebDataRow' does not contain a property with the name X thread.
        If the issue still exists, please provide us with a compilable sample with portable data so that we can reproduce and debug the issue locally. This should help us narrow down the cause of the problem. Your time and cooperation are appreciated.
