does anybody know if it's possible to have the cell merging feature in the ExtJs grids?
then is the ExtJs grid working exactly in the same way in all browser and in the Android phones browser as well?
Thanks!
Out of the box a Grid(View) will never support this and negative margins won't work on all browsers. The more I think about it I must say no, you can't do this a save way.
The only possible solution is a custom rendered Table with a custom storebind. But I wouldn't do that.
Maybe this answer is kind of late, but it is a solution, it was created by a Sencha developer:
Row Spanning Solution.
And he also gives some suggestion here.

I´ve spent a couple of days dealing with an issue about grids' vertical scroll. Scrolls just stop working under some unknown conditions, I mean, it is not deterministic I think.
My application has lots of grids and most of them work perfectly always but just a couple of them just don´t.
I found this Extjs Grid scroll dons't work after application running while that describes the same problem that I have currently, however a migration to a newer version is not the solution for me because after do it (yes, I did it but rolled it back) I found more problems that it is risky enough to discard given the applications is going to production in a few days.
Does someone have a solution, patch, hack or whatever to workaround this problem?
We are using extjs 4.0.7.
The issue with scrolling is localized to 4.0.x-4.0.7 releases due to Sencha's attempt to use virtual scrolling technique.
As you have discovered this strategy backfired and has since been reverted to native scrolling.
Your issue is solvable by upgrading to 4.1+ release.
Try to using:
grid.reconfigure(store,null);
Where:
grid: Grid that is modify.
Store: it's the original store.
null: value for 'new' columns.
See the comment too: reconfigure function on Sencha Api 4.0.7
I'm a rank newbie at animations and so on in Siverlight, and have a need to create an expandable panel, which can be used as a help facility. The idea is that the screen would have a small button at the top-right, and when clicked, this would animate the width of a panel containing help info from zero to some width. Clicking the button again would shrink the help panel back to zero width.
This sounds like it ought to be really easy, and in WPF it is, but as Silverlight doesn't seem to support a lot of the functionality of WPF, I'm struggling badly here.
I looked at the expander control from the toolkit, but as far as I can see, this doesn't do what I want, as the control always takes up the same screen area. I want the expandable panel to disappear when it's not in use.
Anyone able to provide a simple example of how this could be done? Note that I'm using SL4, not SL5.
Thanks very much in advance.
If you've got access to Expression Blend, this can (almost) all be done in XAML.
This is a good place to get started
Found another SO question where someone posted XAML to do something almost identical...
Silverlight Project - Slide-in and out Panel - How?
Hope this helps someone else :)
can you please tell me how to implement auto suggest in sencha .I googled it and found two or three solution .But all solution auto suggest using web service ,But i have array of data ,from this data(example names ) i want to use this array in autosuggest .can you modified this link so as i can use this.
i found these links
https://github.com/martintajur/sencha-touch-2-autocomplete-textfield
take a look at this example "Custom Search Fields "
http://dev.sencha.com/deploy/ext-4.0.0/examples/form/forum-search.html
TypeAhead is build-in ExtJS combobox. You can hide the trigger and it will look like a textbox with autosuggest.
Look at this page for a good tutorial on how to customize your combobox.
Take a look at my blog, it may be helpful to you. Sencha touch 2 auto complete.
It is possible to have Master-Detail chart in HighCharts:
http://www.highcharts.com/demo/dynamic-master-detail/dark-blue
And this is very cool. Has anyone ever seen the same in Sencha ExtJS 4.0 or has an example of that?
It's not that difficult. Have a look at
http://docs.sencha.com/ext-js/4-0/#!/api/Ext.chart.Mask
In the first code chunk it explains how to get zooming functionality. With a bit of workaround you can get it to reset itself into the newly select zoom level.
I'd like to create a Winform app (Mono support would be a huge plus) to display a grid of rapidly updating numbers, while not running into redraw problems while scrolling.
From searching around I've found:
Telerik GridView
which seems to be exactly what I want. Is the Telerik path the way to go? Or is the capability available within the standard .NET tool set? If so, which widgets should I be looking at to implement such an application?
Thanks in advance for your help!
All the Grid components from vendors are going to have performance issues if you change the attached values very very quickly. So if you need high performance you really need to create your own. If you are concerned only about flicker and the update does not need to be amazing quick then you will be fine with Telerik or indeed any other vendors Grid component.
You could consider implementing Virtual Mode on the Telerik RadGridView to overcome any performance issues you might encounter.
The demo application included with the controls contains an example of a rapidly updating grid. Although its just a small demo, if you resize the window to be smaller the scrollbar will appear and you can scroll without any redraw issues. You can access the demo under GridView -> Performance -> High Refresh.
Unfortunately, the Telerik WinForms controls aren't compatible with mono.
