  Hi !

  In the link below :

  https://stackblitz.com/edit/angular-kfj76q

  this.allCountries is array and I want to achieve the same functionality that once a country is selected it should not be repeated in the second row.Here I need this .allCountries to be an array of objects instead of a plain array so that my functionality will be achieved
  
  Any pointers will be helpful for me.

  Thanks,
  
  Siva

  Hi Siva,

  As part of the design dataMaps are applied on the column level and not the cell level. So it is not possible to achieve the required behaviour with dataMaps where display text and binding values are different.
  
  In this case, you could use ComboBox as the editor for the cell. Please refer to the following sample which demonstrates the use of Custom editors:

  You can achieve the desired behavior using dataMap only. In the beginningEdit event, instead of getting a whole new array, you could just filter out the items from the datamap, that are already added to the rows. Please refer to the sample below:
