I have a grid with the multiColumnSort property to be able to order the data depending on the columns which were clicked. The problem is that I can only have 3 columns selected. In the ExtJS docs is a hint which indicates to use the 'Ext.util.Collection' to adjust the multiSortLimit property. However, I do not know how to use the 'Ext.util.Collection' for the grid.
The Link to the docs: https://docs.sencha.com/extjs/6.5.3/classic/Ext.util.Collection.html#cfg-multiSortLimit
You need to reference to Ext.util.Collection in Store.
You can do it by : store.getData() and next use setMultiSortLimit on it to change multiSortLimit.
store.getData().setMultiSortLimit(5);

I got requirement to set column title per condition.
No Grid method allows me to set column title after table gets rendered.
I tried with setting new title via manipulating its value in options.
But after that, I'll need to call refresh() method to show my new title.
Because in the grid, I always have some columns hidden dynamically.
Refresh() method will make these hidden columns showing again on the screen and I don't want it.
So, is there a way to set new value to column title?
Thanks.
For hiding individual columns, you can use the hideColumn, showColumn and isHidden methods.
You can also use the visible column property to set column visibility at initialization time.
There is no setTitle() method currently implemented, but you can email Shield UI's support and ask them to implement that for you. Depending on their load, they might do it real quick.
Until that is implemented, you can always update the title by using jQuery.
I have an array of objects that I want to show in ng-grid. Each row has a boolean property isVisible. In the ng-grid I want to show only the rows where isVisible is true. The other rows should be completely hidden.
I have tried using a rowTemplate and databinding a ng-show to isVisible. That hides the content of the row, but leaves the actual row in place, showing an empty row.
I have tried using filterOptions, but can't figure out the correct syntax to do such a filtering. I couldn't find any good documentation on how to set it.
I have even tried modifying the gridTemplate in the ng-grid source, by trying to add a filter on ng-repeat=\"row in renderedRows\", but I haven't gotten that to work either.
I guess I could modify the array itself, by temporarily removing rows, but I would prefer not to do it that way, since I have to be able to show the rows again (It is actually an expander that I'm doing, that should hide/show sub-rows)
Try also conditionally setting the height of the row in the template to '0' based on isVisible or use a CSS class with ng-class. Play with the CSS of it until you get the desired effect and then you can use that in your template.
This sounds like the type of thing that would benefit from using height and CSS animations actually so it opens and closes with an animated style. If you have a jsFiddle sample I'd be happy to try and help.
Edit: After looking at how the grid actually lays out it's rows (absolutely positioned) you only really have two options I can think of:
1) Filter the data you are binding to the grid through a function like dataVisible() but keep the full data list internally in the controller so you can show/hide easily
2) Submit a patch to the ng-grid project (or fork it) with the filtering capability you are looking for. Out of the box it doesn't appear to support this scenario.
Folks,
I am using ng-grid to display a list of items.
I want to give my users ability to rearrange the rows in the list.
i.e move the rows up and down as they please.
Now,
However when I update the grid data in the backend i.e say change the index of a particular row, that row does not automatically change locations in the front-end.
What am i missing here ?
I have created a plunker to describe the problem
http://plnkr.co/edit/s1hrTSqF2zeZo3Btaln0
The grid doesn't use the index of the array to order it, so even if you are changing it, because the data is still there nothing happens.
What you could do is define an order field and update the value then changing the values as shown in this plukr. The order field you can hide it from the grid if required using columnDefs to explicitly defined which column should be shown.

I'm actually not sure if this is possible, but I will ask it anyway. I have a group of accordion controls, and within the content body of each I need to display a grid panel. The grid panel needs to have a click event attached to it. I have tried simply creating the grid panel and setting the html property of the accordion to it, but this produces no content.
Is there somehow I can achieve the above?
You cannot have html content (inserted by the property) along with any other content. If you add any item the html property value will not set/overriden. But for sure you can place anything you want into one accordion panel. Even a grid. But for that case, and based on the last question, I would recommend you to reference the view into the grid. You may do this simply by using a ComponentQuery
The click events can be applied by using the control function of the controller.
For your basic understanding:
In ExtJS you seldom use plain html code. In most scenarios you use any sort of component. All is nested within the items-array or dockedItem-array. Items within these arrays get also processed by the layout system.
Some Query examples applicable to the control function
In the following this refers to the controller itself.
You know the Id of the grid (normally you didn't do this). Id's are marke by a starting #
control({'#yourId': {itemclick: this.onItemclick }});
You know the xtype and that there is only one instance of this type. You can also describe a path by using spaces between the xtypes.
control({'grid': {itemclick: this.onItemclick }});
You have set a custom property to grid (you can refer any property this way). This one is fully compatible the the one above. I recommend this one in your case
control({'grid[customIdent=accordionGrid]': {itemclick: this.onItemclick }});
This are just some ways to use ComponentQueries, there are more. For a more detailed explanation you should refer the sencha API for ComponentQuery
Also note that every component implements the up() and down() methods which also support ComponentQueries.
I forgot to mention: For a control the query strictly need to return just one result (only the first one will be taken) a ComponentQuery on the other hand can return multiple results.
This is perfectly possible but the accordion's body is not the place to put that in. You'll need to add it to the items: [] array of the accodion. The body (or html) only accepts html.
Example:
http://docs.sencha.com/ext-js/4-1/#!/example/layout/accordion.html
this one has a grid within it.
I have a requirement to create a custom form field that is basically an extjs grid. The user should be able to click a result in the grid. This clicked result should then become the fields value. Also, this field needs to extend Ext.form.field. Here's what I got:
Ext.define('MyApp.field.Grid', {
alias: 'widget.GriedField',
extend: 'Ext.form.field.Base',
I'm a lot of confused on how to add a grid to form field base. Looks like form field base's template expects HTML. How do I get it accept a component?
If you just need to select a value from a list of items. Why not use a combobox?
If you need to select multiple items. There is an example of how to use the MultiSelect ux component in the documentation examples.
http://docs.sencha.com/ext-js/4-1/#!/example/multiselect/multiselect-demo.html
If you really must use a grid. Then I wouldn't bother with trying to create a field type and cause yourself grief.
Add a listener to your grids selectionchange event and update a hidden field in your form with the value you want from the grid. Job done.
I ended up putting the grid on a form indirectly through creation of dependencies on my model.
My model has master-detail, which the detail is just a store reference. I found that using associations did not work for me.
So, in adding a field to a form, I have something that manages changed events for the model (master record) and the detail stores.
