Documentation Error for Query Builder SetRule method?

On this documentation page it shows 
public QueryBuilderRule ImportRules = new QueryBuilderRule
{
    Condition = "or",
    Rules = new List<RuleModel>{
        new RuleModel { Field = "EmployeeID", Value = "1001", Operator = "notequal" },
        new RuleModel { Field = "Country", Value = "England", Operator = "equal" }
    }
};

private void setRules()
    {
        QueryBuilderObj.SetRules(ImportRules);
    }


However, the SetRules method takes a RuleModel object and not a QueryBuilderRule object in the latest version.

Thanks, but know that search is not working for us until we get a working example. 

  • Missing semi-colon in getSQL and getRules methods
  • If we set an import rule then we SetRulesFromSql per the example with a button, the UI updates properly; however, if we call the getSQL method via another button, the returned sql is the original import rule and not the changed rule.
e.g.

    Set Rule
    Get SQL

   
       
           
           
       
   

        protected QueryBuilderRule ImportRules = new QueryBuilderRule()
        {
            Condition = "and",
            Rules = new List()
            {
                new RuleModel { Label="Name", Field="Name", Type="strig", Operator="equal", Value = "Alpha" },
                new RuleModel { Label="Code", Field="Code", Type="string", Operator="equal", Value = "FLKIN" }
            }
        };
        protected void setRules()
        {
            QueryBuilderObj.SetRulesFromSql("Name LIKE ('%Ch%')");
        }
        protected async void getSql()
        {
            RuleModel actRule = new RuleModel()
            {
                Condition = QueryBuilderObj.Rule.Condition,
                Rules = QueryBuilderObj.Rule.Rules
            };
            RuleModel rule = await QueryBuilderObj.GetValidRules(actRule);
            string sql = await QueryBuilderObj.GetSqlFromRules(rule);           // returns the original ImportRules and not the setRules
       }

Query – 1: Missing semi-colon in getSQL and getRules methods 
 
We have checked your reported issue we will consider this and correct it in our online documentation site. This documentation will get refreshed in our upcoming release. 
 
Qurey -2: If we set an import rule then we SetRulesFromSql per the example with a button, the UI updates properly; however, if we call the getSQL method via another button, the returned sql is the original import rule and not the changed rule. 
 
We have checked your reported issue, To Resolve this issue by using GetRules method. Please find the below code snippet: 
 
@using Syncfusion.EJ2.Blazor.QueryBuilder 
@using Syncfusion.EJ2.Blazor.Buttons 
 
<EjsQueryBuilder Columns="@Columns" DataSource="@EmployeeDetails" @ref="QueryBuilderObj" Rule="@ImportRules"></EjsQueryBuilder> 
<EjsButton CssClass="e-primary" @onclick="setRules">Set Rules</EjsButton> 
 
<EjsButton CssClass="e-primary" @onclick="getSql">Get SQL</EjsButton> 
 
@code { 
        EjsQueryBuilder QueryBuilderObj; 
 
    public List<QueryBuilderColumn> Columns = new List<QueryBuilderColumn> 
{ 
    new QueryBuilderColumn{ Field = "EmployeeID", Label = "Employee ID", Type = "number" }, 
    new QueryBuilderColumn{ Field = "FirstName", Label = "First Name", Type = "string" },

    new QueryBuilderColumn{ Field = "Country", Label = "Country", Type="string"}, 
    new QueryBuilderColumn{ Field = "City", Label = "City", Type = "string"} 
}; 
 
    public List<Employee> EmployeeDetails = new List<Employee> 
    { 
        new Employee{ FirstName = "Martin", EmployeeID = "1001", Country = "England", City = "Manchester", HireDate = "23/04/2014" }, 
        new Employee{ FirstName = "Benjamin", EmployeeID = "1002", Country = "England", City = "Birmingham", HireDate = "19/06/2014" }, 
        new Employee{ FirstName = "Stuart", EmployeeID = "1003", Country = "England", City = "London", HireDate = "04/07/2014"}, 
        new Employee{ FirstName = "Ben", EmployeeID = "1004", Country = "USA", City = "California", HireDate = "15/08/2014" }, 
        new Employee{ FirstName = "Joseph", EmployeeID = "1005", Country = "Spain", City = "Madrid", HireDate = "29/08/2014" } 
    }; 
 
    public class Employee 
    { 
        public string FirstName { get; set; }

        public string Country { get; set; } 
        public string City { get; set; } 
        public string HireDate { get; set; } 
    } 
 
    protected QueryBuilderRule ImportRules = new QueryBuilderRule() 
    { 
        Condition = "and", 
        Rules = new List<RuleModel>() 
            { 
                new RuleModel { Label="FirstName", Field="FirstName", Type="strig", Operator="equal", Value = "Martin" }, 
                new RuleModel { Label="EmployeeID", Field="EmployeeID", Type="string", Operator="equal", Value = "1001" } 
            } 
    }; 
    protected void setRules() 
    { 
        QueryBuilderObj.SetRulesFromSql("FirstName LIKE ('%Ch%')"); 
    } 
    protected async void getSql() 
    { 
        RuleModel actRule = await QueryBuilderObj.GetRules();  
        RuleModel rule = await QueryBuilderObj.GetValidRules(actRule); 
        string sql = await QueryBuilderObj.GetSqlFromRules(rule);           // returns the original ImportRules and not the setRules 
    } 
} 
 
 
We will change this code snippet in our documentation site and this documentation will get refreshed in our upcoming release.  
 
For your convenience we have prepared a sample. Please find the below sample link:
