Question

I’m building an application that displays some results in a grid, using the Ext.NET controls.
The grid is created dynamically, in the C# code-behind. I would like to let the user see the results in a grouped grid, grouped on the first column in the grid.
I want to do this dynamically, from C#, by changing the existing grid.

How should I proceed, what properties should I use?

Answer 1

You need to use GroupingStore
To dynamically change grouping, you need to use this store’s groupBy and clearGrouping methods.

Here is good example from sencha –
Grouping.html (js source code – grouping.js)
