Grid with dropdown that contains fixed set of values but shows initial value from dataset

Deanna Delapasse

Asked On April 28, 2019 01:47 AM UTC

Using this grid I want the priority column to start with the "Priority" value from the dataset but then show the set of values defined in dropData. This configuration almost works but it won't show the initial values of priority. If I remove the ng-template, the starting value is shown correctly, but obviously then the dropdown doesn't work. How can I have both?

<ejs-grid id="queueGrid" [dataSource]='queueList' [editSettings]='editSettings' height='515px'>

<e-columns>

<e-column field='priority' headerText='Priority' width=150>

<ng-template #template let-data>

<div>

<ejs-dropdownlist id='ddlelement' [dataSource]='dropData' ></ejs-dropdownlist>

</div>

</ng-template>

</e-column>

</e-columns>

</ejs-grid>

public dropData = ['Pri 1', 'Pri 2', 'Pri 3', 'Pri 4', 'Pri 5'];

queueList: Object[] = [

{ id: "c:/a/b/c/file.txt", filename: "file.txt", size: "1234", priority: 'Pri 1', tag: "blah blah", uploaded: '1233', filepath:"c:/a/b/c" },

{ id: "c:/a/bbb/c/myzip.zip", filename: "myzip.zip", size: "233", priority: 'Pri 2', tag: "blah blah", uploaded: '0', h:"c:/a/bbb/c" },

{ id: "c:/a/b/cccc/myzip.zip", filename: "myzip.zip", size: "456456", priority: 'Pri 5', tag: "blah blah", uploaded: '0', filepath:"c:/a/b/cccc" }

];

ngOnInit(): void {

this.editSettings = { allowEditing: true, allowDeleting: true };

}

Hi Deanna,

Greetings from Syncfusion support.

We have checked your query and you can achieve your requirement by using the below way. We have prepared a sample where the grid shows initial values of “CustomerID” column and dropdownlist for that column.

Please refer the below code example and sample link.

[app.component.ts]

@Component({

selector: 'app-root',

template: ` <ejs-grid [dataSource]='data' [editSettings]='editSettings'>

<e-columns>

<e-column field='CustomerID' headerText='Customer ID' width=150>

<ng-template #template let-data>

<span>{{data.CustomerID}}</span> // you can show the initial value like this.

<ejs-dropdownlist id='ddlelement' [dataSource]='dropData' ></ejs-dropdownlist>

</div>

</ng-template>

</e-column>

</e-columns>

</ejs-grid>`,

styleUrls: ['./app.component.css']

})

export class AppComponent implements OnInit {

public data: object[];

public dropData: any;

public editSettings: EditSettingsModel;

ngOnInit(): void {

this.data = data;

this.dropData = ['VINET', 'TOMSP', 'HANAR', 'SUPRD', 'VICTE'];

this.editSettings = { allowEditing: true, allowDeleting: true };

}

This solution shows BOTH the initial value and the dropdown's value at the same time. I want the initial value of the dropdown to BE the initial value.

This should be a very common pattern. I feel like [value]={{data.CustomerID}} should work, but that doesn't work for me.

Figured it out! Just needed to remove the {{}}

<e-column field='priority' headerText='Priority' width=150>

<ng-template #template let-data>

<div>

<ejs-dropdownlist id='ddlelement' (change)="onChange($event)" [(value)]='data.priority'

[dataSource]='dropData' (select)="priDDSelect()" ></ejs-dropdownlist>

</div>

</ng-template>

</e-column>
