  • \thank you for reply

    yes when a user enter driver no or a specific string in specific format for example AS123456 s

    if the format is not valid  in AS123456s then it show a message  not valid format error

    if its validated then it check against the already stored  data for example  AS123456s in the  database if exist show message Already exist

    thank you

    Hi ,

     1 * ) You can use duplicate detection rule find already license number exist in that string field.

     2 *) If you are going to write as a plugin weather already license no exist meas use retrieve multiple method .

    Eg : 
                        QueryExpression Contact = new QueryExpression { EntityName = "Schema Name", ColumnSet = new ColumnSet("field schema name") };
                        Contact.Criteria.AddCondition("field schema name", ConditionOperator.Equal, "AS123456s");
                        EntityCollection ContactRetrieve = service.RetrieveMultiple(Contact);

    You can get the License no field run time and pass into the parameter.

      3*) To validate Driving license no you can use java script. 

    Or you can do with plugin. 

    have a look at bellow link

  • Hi,

    You have two option for this.

    - JavaScript.

    Write JavaScript that will check the format of the text entered and abort the save operation. us below code to abort the save operation.


    - Validation Plugin.

    Write Pre Operation Plugin that will validate the Format and existence of with same license.

    You can throw an error message after validation in plugin.
