Hi Edmund, 

Thanks for contacting Syncfusion support. 

To add validation in grid control, use validationRules property of columns. If you have different field for both telephone and mobile number, use minlength and maxlength jQuery validation method. For example, in this sample we set validation for phone number using maxlength and minlength validation method.  

Find the code example and sample:  

@(Html.EJ().Grid<object>("FlatGrid") 

    .Datasource((IEnumerable<object>)ViewBag.datasource) 

    .AllowSorting() 

         ---------- 

     }) 

       .Columns(col => 

        { 

          --------------- 

            col.Field("Phone").HeaderText("Phone").ValidationRules(v => v.AddRule("required", true).AddRule("maxlength", 6).AddRule("minlength", 6)).TextAlign(TextAlign.Right).Width(75).Add(); 

        }) 

    ) 

Sample: http://www.syncfusion.com/downloads/support/forum/128126/ze/Sample145862820067657 

Refer to the Help document for the validation.  

https://help.syncfusion.com/aspnetmvc/grid/editing#column-validation 

If you need to validate phone and mobile number in a single field, use custom validation. In addition to jQuery validation methods, you can also add your own custom validation methods for a specific column. Function call to custom validator function to be mentioned within ValidationRules property of Columns. 

 

For more information, please refer the below document and online sample.

Hello. Is there a way to validate a phone number? I have been doing the ff_valuenotempty, but it will accept anything someone puts there. Is there a way to see if its a number?

I think the easiest way would be to check that it is the appropriate number of digits, with no spaces, but I understand the integer validation only checks to see if its an integer, not one of a specific length.

Any thoughts?

Hi oddssatisfy,

Query: Is there a way to validate a phone number? I have been doing the ff_valuenotempty, but it will accept anything someone puts there. Is there a way to see if its a number?

You can validate the phone number using the below code snippet,

@(Html.EJ().Grid<object>("HierarchyGrid")

 

                     ….

                    .Columns(col =>

                    {

                        …

                        col.Field("PhoneNumber").HeaderText("Phone number").Width(110).ValidationRules(v => v.AddRule("required", true).AddRule("digits", true).AddRule("maxlength", 10).AddRule("minlength", 10)).Add();

                    })

In the above code snippet, we used the digits validation rule and the maxlength and minlength validation rules. When using the digits validation rule, you can only enter the digit .

Please refer to the below sample,

Please refer to the below help documentation,

https://help.syncfusion.com/aspnetmvc/grid/editing?cs-save-lang=1&cs-lang=razor#column-validation

https://jqueryvalidation.org/digits-method/

And you can also add your own custom validation methods for a specific column. Function call to custom validator function to be mentioned within ValidationRules  property of Columns.
