Duplicate Check

This will take one to the True part (If duplicate value exist) where one have to add all the actions required to be performed. Once this is completed click on next button to go to the False part (If duplicate value does not exist) and add all the actions required to be performed.Whenever there is a need to check for duplicate value in database use this Action. Duplicate Check is similar to If...Then..Else the only difference is that here the value is checked from database.

For this action to work one needs to first create a SQL query and related Web-service as it is this that is called by this Action.

This action also has three parts or steps.

In the first part select the control whose value one wants to check for duplicate in database, then select the Data source that is the SQL Query that will be executed to check for duplicate value in database and finally set the parameters of the selected query.

Now click next button.
