I have an ASP.Net page with a RadGrid which is populated by the SQLDataSource.

I am trying to set up the RadGrid so the user edit some fields in the RadGrid for a record and click on update. But I cannot get it to work. When clicking on update, I get "ORA-01036: illegal variable name/number" error.

I am connecting to an Oracle database.

In looking at your demos, none of them use EditMode = "InPlace". They either use an Edit Form or some custom things like textboxes, comboboxes, etc.

I have tried having a simple update command in SQLDataSource like the following:

UpdateCommand="UPDATE ADMIN.RSDC_SCRAP_CREDIT_RATE SET LAST_UPDATE = CURRENT_DATE"

That statement should update the LAST_UPDATE field with the Current Date/Time for all the records but it is causing the error as well. That statement was just a test to see if the parameters in the SQLDataSource is causing the error and/or the Update statement is causing the error.

Usually I set up a RadGrid to use NeedDataSource but alot of your demos and documentation for editing and updating records in the RadGrid indicate using SQLDataSource instead.

Either way I am trying to find a way for the user to edit fields in the RadGrid and update the record.

Please help!

Hi,

Please note that using SqlDataSource with Oracle database is not directly related to the RadGrid control. This is a general programming issue.

Nevertheless, check out the following thread that discusses similar error and how it can be resolved.

http://stackoverflow.com/questions/21375288/ora-01036-illegal-variable-name-number-when-running-query-through-c-sharp

Also, examine the following article that discusses how you can use the SqlDataSource with Oracle database.

https://msdn.microsoft.com/en-us/library/92ceczx1(v=vs.85).aspx

In case you would like additional information on how to use automatic CRUD operations in RadGrid you would find the article below interesting.
