  • DisplayName - The display name of the activity.


  • Column - A DataColumn object that is to be appended to the column collection of the DataTable. If a variable is added to this property field, all of the properties under the Options category are ignored. This field supports only DataColumn objects.
  • ColumnName - The name of the new column you want to add in the specified DataTable Object. This field supports only strings and String variables.
  • DataTable - The DataTable object in which you want to add a column. This field supports only DataTable objects.


  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.
  • TypeArgument - A drop-down list that enables you to choose what .NET datatype you want to use with the activity. The newly added column will only accept the values of the selected datatype.


  • AllowDBNull - Specifies whether new values are allowed in the new column for rows that belong to the table. By default, this check box is cleared.
  • AutoIncrement - Specifies if the value of the column increments automatically when a new row is added. By default, this check box is cleared.
  • DefaultValue - Specifies the default value for the new column when creating new rows. The value must be of the type stated by the TypeArgument property.
  • MaxLength - Specifies the maximum length for each row of the new column. This field supports only Int32 variables.
  • Unique - Specifies that the values in each row of the new column must be unique. By default, this check box is cleared.
