Add Columns Programatically Before They Are Auto Generated

[Marius Lian]

Hi Syncfusion,

I could probably add columns something like this at any time:

var colObj = { headerText: "Ship City", field: "ShipCity", width: 120 };  

gObj.columns.push(colObj);

gObj.refreshColumns(); 

But I would like to add columns programatically but as early as possible. So basically add this programatically at run time:

Would it be possible to add this att the data grid's loaded or created event? And if so what is the best way to add it?

Thanks,

Marius

Hi Marius Lian, 

 

Greetings from Syncfusion Support. 

 

Query #1: Would it be possible to add column to Data Grid in Load or Created event ? 

 

We have analyzed your query and we can understand that you need to push columns to Grid as early as possible. Yes, you can add columns to Grid in the Load or Created events of Grid. We suggest you to use Load event. This event allows customization of Grid properties before rendering. We have achieved your requirement and created a sample based on your query. Please refer the below code snippet and sample link for more information. 

 

App.vue 

 

<template> 

  <div id="app"> 

    <ejs-grid 

      id="Grid" 

      ref="grid" 

      :dataSource="data" 

      :allowPaging="true" 

      :editSettings="editSettings" 

      :load="load" 

    ></ejs-grid> 

  </div> 

</template> 

<script> 

import Vue from "vue"; 

import { GridPlugin, Edit, Page, Toolbar } from "@syncfusion/ej2-vue-grids"; 

import { data } from "./datasource"; 

Vue.use(GridPlugin); 

export default { 

  data() { 

    return { 

      data: data, 

      editSettings: { 

        allowAdding: true, 

        allowEditing: true, 

        allowDeleting: true 

      }, 

      toolbar: ["Add", "Edit", "Delete", "Update", "Cancel"] 

    }; 

  }, 

  methods: { 

    load: function() { 

      var colObj = { headerText: "Ship City", field: "ShipCity", width: 120 }; 

      this.$refs.grid.ej2Instances.columns.push(colObj); 

    } 

  }, 

  provide: { 

    grid: [Page, Edit, Toolbar] 

  } 

}; 

</script> 

<style> 

@import "https://cdn.syncfusion.com/ej2/material.css"; 

</style>
