"FixedId" is neither a DataColumn nor a DataRelation for table

[courtney shoell]

Hi,

I am using Rad-grid hierarchical. when i am trying to rebind the grid after update or insert. i am getting "FixedId" is neither a DataColumn nor a data Relation"  Here i added my design and code behind please let me know where i am going wrong.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" Skin="Black" OnItemDataBound="RadGrid1_ItemDataBound" OnItemCreated="RadGrid1_ItemCreated"

Hi ,

This erratic behavior is due to the fact that your FixedId column cannot access its required DataField. Please check your DataSource configuration closely and see if this DataField's exact name is "FixedId".
Hope this helps,please try and let me know.

Thanks,
Princy

Hi There,

I ran into this issue as well and searched through all of the forum posts to no avail.  After further debugging I found that we were making a call to the Grid.DataBind() explicitly as well as at the wrong time.  This forced the grid into rebinding before it was ready and caused this cryptic error.  We come from many years of explicit databinding in code and transitioning to the NeedsDataSource/Rebind() approach has come with some pain such as this issue, although this binding approach of the grid is very very nice.  Hopefully sharing this here will help someone else in the future.

Regards,
Robert

Hello Rob,

Thank you for sharing your experience in this matter. I hope this information will prove helpful to other developers as well.

Generally, please note that using DataBind() is not recommended. Performing complex grid operations such as Inserting, Deleting, Updating, Hierarchy relations, Grouping, Paging, Sorting, Filtering, etc. require accommodating appropriate database operations.  Therefore, we suggest you to avoid Simple Databinding and strongly recommend the use of more advanced databinding methods, which automatically handle the aforementioned functions:
Declarative DataSource
Advanced Data Binding

In cases when the grid should be rebound externally and exclusively, Rebind() should be used instead.

Eyup
