Grid with a custom DropDownList as an editor not working dataItem.set value

[Liton]

Dear Concern,

I'm trying to select frist value from dropdownlist if have only one value. I have grid Add row button. When I'm clicking on Add line button (please see attached image) grid creating one row job drop-down should automatically bind if job drop-down has one value.Please see the attached file. This will help users to fill the job dropdown more quickly (no need click on dropdown) if just one job in dropdown.

If only one job in dropdown and user clicks on Add Line, Make it so that the JOB# automatically fills. 

I'm trying below way but its not working. 

var dataItem = _getGridCurrentDataItem(PARTS_GRID_CONTROL_ID); 

if (jobs.length == 1) {                        
                        if (dataItem) {
                            dataItem.set("SerRecID", jobs[0]);                            
                        }
                    }

Thanks !

Liton

Issue is in the validation. If i remove the validation then its work fine but I need validation also. How can I achieve that ? Please see the code below my validation code. Thanks !

model: {
                            id: "PartsUsedGuid",
                            fields: {
                                SerRecID: {
                                    from: 'SerRecID', type: 'string', defaultValue: '', validation: {
                                        custom: function (input) {                                            
                                            input.attr("data-custom-msg", "Please Select Job Id");
                                            console.log("ltnPartsUsedGuid");
                                            return input.val() != "" && input.val() != "0";
                                        }
                                    }
                                },

Hi, Liton,

The easiest way to achieve the desired result is to have a defaultValue in the data source schema model field.

It appears that you are using the MultiColumnComboBox, so I prepared this example for you:

https://dojo.telerik.com/@bubblemaster/AMURUGEL

fields: {
  SerRecID: {
        defaultValue: '49777', type: 'string',

On a side note, the field.from mapping is not necessary since the field is not a different one.

Let me know if you expected a different behaviour if you have more than one job options. An alternative could be to capture the beforeEdit event and assign the job value:

https://dojo.telerik.com/@bubblemaster/acevogog

 beforeEdit: function(e) {
  if (e.model.isNew()) {
       e.model.ProductName = "Alice Mutton"
  }
}
