Ext.NET & Codebehind

[plykkegaard]

I have noticed quite a few developers requests samples on to use Ext.NET in codebehind
I have started a series of article on how to accomplish this
http://looksharp.dk/?tag=/ExtNET

Samples are coded for Ext.NET ver 2.0 Beta

Excellent posts. Thanks for sharing!

Hi Peter,

Do you have a Twitter account, or any other social profile/url/business/service you would like to promote... other than your http://looksharp.dk/ website?

[plykkegaard]

Like eg a proper signature? ;-)

Can you add some controls (buttons command) to the gridpanel in the same codebehind? Or give us some address to see it

Like in a statusbar or toolbar?
It's quite easy, I will see what I can do this weekend

My next examples would have been around generic http handlers and also how to build a dynamic grid based on data layout, I can postpone those
Interesting with the generic approach as this really explains why you want to use code behind


Or give us some address to see it .
Sorry no live preview atm
When more complex examples comes around I need to do something about this part and also let you download full solution except for ext.net, but this belongs to the future ;-)

Quite forgot, you can add buttons to the gridpanel
Eg

Buttons = {
new ext.Button()
{
Text = "Refresh",
Icon = ext.Icon.ArrowRefresh,
OnClientClick = "#{store}.load();"
}
}

Dear Peter!

I think I have more control of programming from the code behind.
I think Geoffrey should focus on MVC 3 or 4, and drive users in that way. It is a comfortable way to communicate Client Side and Server Side.

If you were to choose one of 4 methods for CRUD program which are in the example2/gridpanel/SavingVariation: HttpHandler, Web Services, StoreEvent or StoreCustumLogic, Which Do you prefer? What is more easy?

Best Regards,

Currently I am using store events when saving data but httphandlers to retrieve
Our main app coded using ext.net is from 09, it's more historic reasons than anything else

Down the road I have changed all data load to use httphandlers
I started to change all my combos is I have quite a few in my gridpanel

I have been looking at webservices but cross site it's difficult to handle as you need to use special query string and httpmodules
http://forums.ext.net/showthread.php?17352-JSONP-and-Webservices-versus-Generic-Handlers

As you said MFC/MVC is so much easier eg JSONP is supported out of the box

If you haven't done any apps in MVC and also first timer with Ext.Net you're in for a ball
Imo it's a steep learning curve for both ;-)

I need an example using saving data in httphandler. Because de example CRUD in the Example2.Ext.Net is not working, specific when I delete a row I click save. That is in Ext.Net 2.

Best Regards Peters.

Please create a new thread and describe what you have done and which error is thrown to keep the forum clean and tidy and easy for any user to search and browse - thanks

Is it CRUD grid example you have problems with?
https://examples2.ext.net/#/GridPanel/Saving_Variations/HttpHandler/

This is the example I am converting to use code behind atm
I have some issues with the LINQ to SQL as this is a new to me but otherwise it's just a matter of a search and replace
The code will be broken up ind small functions to demonstrate the power of code behind

I have created a copy of this example
https://examples2.ext.net/#/GridPanel/Saving_Variations/HttpHandler/

Code behind version

Dear Peter!!!

I prove the example CRUD HttpHandler from code behind . Everything is very well. Certainly thanks. Just as you explain a minor trouble with the StoreResponseData.

when I delete a row
it say {data:"", total: 0} Status code : 200, Status Text: ok in the Request Failure Dialog Box.

I willl try to find the problem. In all case this is a straight step.

Best Regards,

Marcos Mejia.

Hi Peter,

in code behind dont exist the dataIndex property of textField, how to save in store ?


Buttons = {
new ext.Button()
{
Text = "Refresh",
Icon = ext.Icon.ArrowRefresh,
OnClientClick = "#{store}.load();"
}
}

[plykkegaard]

in code behind dont exist the dataIndex property of textField
The dataindex property is hidden, you need to do a workaround like eg my buildcolumn method
And it's not a property on the textfield object (editor) but the column object


how to save in store
store.sync takes care of it and calls the generic handler SuppliersSave

When you have the CRUD Grid Example (https://examples2.ext.net/#/GridPanel/Saving_Variations/HttpHandler/) up and running you can use my example instead of the markup code

Please create a new thread in the appropriate forum including a sample to reproduce/work with

Thanks /Peter
