  4. Validate FK Column with custom dialog template

Validate FK Column with custom dialog template

I am working with a grid with custom add/edit template, trying to validate a Foreign Key column.

I can't validate that column with validationRules.

Example attached.

Hi Matteo, 
 
Greetings from Syncfusion support. 

We have validated the provided code example and we suspect that you have customized validation rule in foreignKey Column(“FrontEndCategoryId”) it is cause of the defect. In the below Documentation to know about the existing validation rules  while we editing the grid.  


Please get back to us, if you need further assistance.

I created the custom validation to try and debug the problem.

Even changing the line to:

<ColumnDirective field='FrontEndCategoryId' headerText="Category" width='250px' allowFiltering={false} dataSource={this.FrontEndCatData} foreignKeyValue='ResourcesItalianText' validationRules={{ required: true }} />

it does not matter, the validation is still missing.

Hi Matteo, 

As per your query we have modified teh sample with custom validation on dialog template editing in EJ2 Grid. please refer the below code example and sample for more information. 
[index.js] 

export class DialogTemplate extends SampleBase { 
            constructor() { 
            super(...arguments); 
            .     .     .     . 
            this.customValidate = { required: [this.customFn.bind(this), "Please select ShipCountry"] }; 
        } 
 
        customFn(args) { 
            return args['value'] == "" ? false : true; 
        };  
 
 
    <GridComponent dataSource={orderData} toolbar={this.toolbarOptions} allowPaging={true} editSettings={this.editSettings} pageSettings={this.pageSettings} actionComplete={this.actionComplete.bind(this)}> 
        <ColumnsDirective> 
            .   .    .    . 
            <ColumnDirective field='OrderDate' headerText='Order Date' format='yMd' width='170'></ColumnDirective>

I am sorry but you may have misunderstood my question.

As per title, the validation does NOT work with Foreign Key Columns, your example does not include a FK column.

Hi Matteo, 
 
We have validated the your query and we are tried to reproduce the reported defect in our end but it is unsuccessful. We have applied validationRules on foreignKey column with dialogtemplate editing it is correctly working the validation on ForeignKey column. Please refer the below code example, sample and video demonstrate the reported defect with EJ2 Grid performance. 
 
[index.js] 
 
<GridComponent dataSource={this.data} toolbar={this.toolbarOptions} allowPaging={true} editSettings={this.editSettings} pageSettings={this.pageSettings} actionComplete={this.actionComplete.bind(this)}> 
        <ColumnsDirective> 
            .   .  . 
            <ColumnDirective field='ShipCountry' headerText='Ship Country' foreignKeyField="ShipCountry" foreignKeyValue="City" dataSource={this.fkDataSource} validationRules={{required:true}} width='150'></ColumnDirective> 
        </ColumnsDirective> 
        <Inject services={[Page, Toolbar, Edit, ForeignKey]} /> 
    </GridComponent> 
 
 
 
If you are still facing the face the same issue, could you please provide more information that will be helpful for us to validate further at our end. 
 
  • Share ej2.min script file version.
  • Share the Stack trace  if any script error
  • Please try to reproduce the issue in the above sample if possible
 
Please get back to us, if you need further assistance.

Pavithra S.

Ok the validation does in fact work, but it only triggers on submit, it does not trigger "onLostFocus" like the TextBoxes.
Both in your example and in my code.

Is this behavior intentional?

Hi Matteo, 
 
As per your query, we have created a sample with validation happens while editing input element focusout in the dialog editing in EJ2 Grid. Please refer the below code example to more information. 
[index.js] 

  actionComplete(args) { 
   
     if ((args.requestType === 'beginEdit' || args.requestType === 'add')) { 
                    args.form.addEventListener("focusout", function (e) { 
                        this.ej2_instances[0].validate(); //validate required input elements 
                    }); 
                    if (Browser.isDevice) { 
                        args.dialog.height = window.innerHeight - 90 + 'px'; 
                        args.dialog.dataBind(); 
                    } 
                } 
            }

The fix does work somehow.

But it brakes the form, all the error tooltip get misplaced, as per attached image.

Greetings.
