Edit in Vue Treegrid component

16 Mar 202317 minutes to read

The TreeGrid component has options to dynamically insert, delete and update records. Editing feature is enabled by using editSettings property and it requires a primary key column for CRUD operations.

To define the primary key, set columns.isPrimaryKey to true in particular column.

To use CRUD, inject the Edit module in treegrid.

To get start quickly with Edit Options, you can check on this video:

app.vue

<template>
<div id="app">
        <ejs-treegrid :dataSource='data' childMapping='subtasks' :treeColumnIndex='1' height='270px' :editSettings='editSettings'>
        <e-columns>
                <e-column field='taskID'  :isPrimaryKey='true'  headerText='Task ID'  width=90 textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name'  width=180 ></e-column>
                <e-column field='priority' headerText='Priority' width=80 textAlign='Right'></e-column>
                <e-column field='duration' headerText='Duration' width=80 textAlign='Right'></e-column>
                </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Edit } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data() {
    return {
      data: sampleData,
      editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true }
    };
  },
    provide: {
    treegrid: [ Edit]
  }
}
</script>

• You can disable editing for a particular column, by specifying
  columns.allowEditing to false.

Toolbar with edit option

The treegrid toolbar has the built-in items to execute Editing actions.
You can define this by using the toolbar property.

app.vue

<template>
<div id="app">
        <ejs-treegrid :dataSource='data' childMapping='subtasks' :treeColumnIndex='1' height='270px' :editSettings='editSettings' :toolbar='toolbar'>
        <e-columns>
                <e-column field='taskID'  :isPrimaryKey='true'  headerText='Task ID'  width=90 textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name'  width=180 ></e-column>
                <e-column field='priority' headerText='Priority' width=80 textAlign='Right'></e-column>
                <e-column field='duration' headerText='Duration' width=80 textAlign='Right'></e-column>
                </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Edit, Toolbar } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data() {
    return {
      data: sampleData,
      editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true,  mode: 'Row' },
      toolbar: ['Add', 'Edit', 'Delete', 'Update', 'Cancel']
    };
  },
    provide: {
    treegrid: [ Edit, Toolbar ]
  }
}
</script>

Adding row position

The TreeGrid control provides the support to add the new row in the top, bottom, above selected row, below selected row and child position of tree grid content using editSettings.newRowPosition property. By default, a new row will be added at the top of the treegrid.

The following examples shows how to set new row position as Child in tree grid.

app.vue

<template>
<div id="app">
        <ejs-treegrid :dataSource='data' childMapping='subtasks' :treeColumnIndex='1' height='270px' :editSettings='editSettings' :toolbar='toolbar'>
        <e-columns>
               <e-column field='taskID'  :isPrimaryKey='true'  headerText='Task ID'  width=90 textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name' width=180></e-column>
                <e-column field='startDate' headerText='Start Date' editType= 'datepickeredit' type= 'date' format= 'yMd' textAlign='Right' width=170></e-column>
                <e-column field='duration' headerText='Duration' width=80  textAlign='Right'></e-column>
                </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Edit, Toolbar } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data() {
    return {
      data: sampleData,
      editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true,  mode: 'Cell',  newRowPosition: 'Child' },
      toolbar: ['Add', 'Delete', 'Update', 'Cancel']
    };
  },
    provide: {
    treegrid: [ Edit, Toolbar ]
  }
}
</script>

Confirmation messages

Delete confirmation

The delete confirm dialog can be shown when deleting a record by defining the showDeleteConfirmDialog as true

app.vue

<template>
<div id="app">
        <ejs-treegrid ref='treegrid' :dataSource='data' childMapping='subtasks' :treeColumnIndex='1' height='270px' :editSettings='editSettings' :toolbar='toolbar'>
        <e-columns>
        <e-column field='taskID'  :isPrimaryKey='true'  headerText='Task ID'  width=90 textAlign='Right'></e-column>
        <e-column field='taskName' headerText='Task Name' width=180></e-column>
        <e-column field='startDate' headerText='Start Date' editType= 'datepickeredit' type= 'date' format='yMd' textAlign='Right' width=170></e-column>
        <e-column field='duration' headerText='Duration' width=80  textAlign='Right'></e-column>
        </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Edit, Toolbar } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);


export default {
  data() {
    return {
      data: sampleData,
      toolbar: ['Add', 'Delete', 'Update', 'Cancel'],
      editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Cell', showDeleteConfirmDialog: true },
    };
  },
    provide: {
    treegrid: [ Edit, Toolbar ]
  }
}
</script>

The showDeleteConfirmDialog supports all type of edit modes.

Default column values on add new

The treegrid provides an option to set the default value for the columns when adding a new record in it.
To set a default value for the particular column by defining the columns.defaultValue.

app.vue

<template>
<div id="app">
        <ejs-treegrid :dataSource='data' childMapping='subtasks' :treeColumnIndex='1' height='270px' :editSettings='editSettings' :toolbar='toolbar'>
        <e-columns>
        <e-column field='taskID' :isPrimaryKey='true'  headerText='Task ID'  width=90 textAlign='Right'></e-column>
        <e-column field='taskName' headerText='Task Name' width=180></e-column>
        <e-column field='startDate' headerText='Start Date' editType= 'datepickeredit' type='date' format='yMd' textAlign='Right' width=170></e-column>
        <e-column field='priority' headerText='Priority' width=110 defaultValue='Normal'></e-column>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Edit, Toolbar } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);


export default {
  data() {
    return {
      data: sampleData,
      toolbar: ['Add', 'Delete', 'Update', 'Cancel'],
      editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Cell', showDeleteConfirmDialog: true },
    };
  },
    provide: {
    treegrid: [ Edit, Toolbar ]
  }
}
</script>

Disable editing for particular column

You can disable editing for particular columns by using the columns.allowEditing.

In the following demo, editing is disabled for the Start Date column.

app.vue

<template>
<div id="app">
        <ejs-treegrid :dataSource='data' childMapping='subtasks' :treeColumnIndex='1' height='270px' :editSettings='editSettings' :toolbar='toolbar'>
        <e-columns>
        <e-column field='taskID'  :isPrimaryKey='true'  headerText='Task ID'  width=90 textAlign='Right'></e-column>
        <e-column field='taskName' headerText='Task Name' width=180></e-column>
        <e-column field='startDate' headerText='Start Date' :allowEditing='false' :allowEditing='false' type='date' format= 'yMd' textAlign='Right' width=170></e-column>
        <e-column field='duration' headerText='Duration' width=80  textAlign='Right'></e-column>
        </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Edit, Toolbar } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);


export default {
  data() {
    return {
      data: sampleData,
      toolbar: ['Add', 'Delete', 'Update', 'Cancel'],
      editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Cell' },
    };
  },
    provide: {
    treegrid: [ Edit, Toolbar ]
  }
}
</script>

Troubleshoot: Editing works only for first row

The Editing functionalities can be performed based upon the primary key value of the selected row. If primaryKey is not defined in the treegrid, then edit or delete action take places the first row.
