    I am using treelist to show heirachical data. 

    Both parent and child are stored in same table 

    Sample tables: 


    1. id 
    2. parent id 
    3. category id (drop down on editformtemplate)
    4. description

    When I am creating a child, the parent category id needs to be shown on edit form template

    and when a new parent is being created it should allow user to select the value.

    I am using hybrid approach of automatic CRUD operation and using formtemplate

    Can this be done?

    Hello Swapnil,

    Note that in order to use automatic operations the TreeList must be bound to a declarative DataSource control. Moreover the data source should support such operations and they need to be configured.

    In case you need to implement a more complex scenario with templates it is recommended to update the data source manually.
