Is there a way to add a column to a grid panel dynamically in Ext JS 3.4?
I'm trying to add a Row Expander column to my grid panel.
Like the one here (The first plugin)
I can do it by modifying the ui.js and manually adding a column (Like the one in the code behind), but I'm trying not to.
Any workaround would be highly appreciated!
Edit: I found this for Ext JS 4. Something similar in 3.4?
In 3.4 you have to use reconfigure method on the grid:

More precisely, how to add items to column? I found items only in Action columns.
You need to to add custom property to the column. Steps:
Add Grid panel
Add simple grid column
Select the column, in the filter of configs, write items and click ADD button
Now just find this new config and edit it
Here it's explained in tutorial https://youtu.be/2wTAdPaG2Xk?t=414, I highly recommend watching whole video, there are some cool tricks.
I am trying to implement a ExtJS based grid where users would change column data or enter empty columns. Is there a way to show/enter contents as bullet points on ExtJS grid cell like we usually do in Excel?
Thanks in advance
Check this fiddle - https://fiddle.sencha.com/#fiddle/mpl
The Idea is to use htmleditor as the column editor in your grid. However, there'll be quite a lot of work involved in positioning and styling when the html editor opens up for editing.
The fiddle that I created contains just the editor with no styling so it doesn't open good. And when you try, try editing the first column in third row data.
I need a project about it ,thank you.I am using Ext.grid.gridpanel.As in rowclick event, we can handle row click of grid..Is there any event to handle column click of grid?
i want to select a particular column of grid.
You are looking for headerclick. Also for any more questions like this just look through the extjs documentation per your version. Sencha documents it very well.
I have just started with angularjs. Just wanted to know that if it is possible to create a sub grid inside another ng-grid. There would be some links in a column of the grid and when I click a particular link a grid corresponding to that link should be formed inside the already existing grid.The original grid would be having say 5 columns while the new grid will have say 4 columns. So something on the lines of colspan or something similar is what I look for.
If you are open for writing Angular Directive then you can use any grid ,other than ng-grid which has subgrid feature.
I know like Kendo Grid has subgrid feature and jqgrid has subgrid feature. I wrote a Grid using Google Closure library , this also has subgrid feature.
If I understand your question, you need something like master/details inside grid, it not part of base functionality. nggrid has fixed row height, for virtual scrolling purpose. On our project we have created custom grid plugin base on nggrid
Solution that we used is:
write custom sort function, which populate duplicated rows always below main
when we click expand button we duplicate current row n-times depend on subgrid height
in main row we create css overlay container which hides duplicated rows
load overlay container content via ajax
When we click hide button, we hide overlay, and remove duplicated rows.
I want to implement Grid which loads a very huge amount of data, performing search in grid contents, pagination. The data to grid from serverside.And I want to add rows to grid, delete rows and update the inserted rows in database. I want to know which is better technology to implement grid with the above requirements. Please help me.
Adventages of ExtJs 4.2.1.883 Over Dojo 1.9.2
Better Documentation
Grid has row Grouping
Grid has rowGrouping + selectionModel (checkbox for selecting single, simple, or multiple rows) Together
Grid has rowEditor (Editing all elements of the row at once) and Dojo only has cell editing (one cell by time). This is useful if you want to pre-validate row data before send the row record to the server
Grid has row Summary
They use SASS instead pure CSS
Programming only in JavaScript (you only need index.html everything else is javascript)
Stable MVC (in Dojo you need to use Dojox/MVC which is not 100% stable)
DOM is rendered only one time, only after all JS has finished loading, while Dojo renders twice the same element (First during loading the page and them after dojo has created or modified widgets)
Disaventages of ExtJs Over Dojo
ExtJs is non-free for commercial ussage
For more exact comparison you can see this link:

Althouth it only shows you dGrid vs ExtJs Grid, this could be an starting point. Furthermore, most of my development time is spent in the Grid, so the grid is the most important element in a Business application.
Note: Dojo use LESS for all it's bundled styles and Stylus for Bootstrap Style
Both projects are great. Actually dojo is greater than Extjs. But Ext JS is a relatively young framework (compared to dojo). DOJO grid loads data quicker and allows filtering and sorting of the whole dataset.
However Dojo had several attempts in pushing for some good looking themes. Unfortunately they did not get that “good looking widgets” and “pixel-perfect” layout. Widgets are still difficult to integrate.
