How to read parameters of ExtJS Form on ASP.NET page

[Shehul]

Hello,

I am trying to create ExtJS form and have submit button which when clicked should post to ASP.NET webpage.

Inside asp.net page I am trying to process the parameters received. I am not sure how I can read those parameters(form values) on server side.

Here is my code,

form.submit(
{
clientValidation : true,
url : 'Feedback.aspx',
params:{Para1:'Id',Para2:"email"},
waitMsg:'Saving...',
success : function(form, action)
{
Ext.Msg.show(
{
title : 'Success'
, msg : 'Feedback submitted successfully'
, modal : true
, icon : Ext.Msg.INFO
, buttons : Ext.Msg.OK
}
);
}
,
failure : function(form, action)
{
this.showError(action.result.error || action.response.responseText);
}

I am hitting breakpoint on Server's Page Load but not sure how to read parameter values.

Please reply if this is not correct way do I need to create webmethod and if yes than please point me to an example to read this parameters in the webmethod.

Please reply ASAP.

Thanks,
Shehul

In ASP.NET use the Request object's Form property.



Request.Form["MyVarName"]

Hi gurufaction (http://www.sencha.com/forum/member.php?76220-gurufaction),

Thanks for the reply. I will mark your answer but quick question now, how do I reply to the ExtJS form back that form is submitted successfully or get error.

I am using Response.write but the Reply is not JSON.

Thanks,

In what format is your reply?

[Shehul]

Its XML.

Define an XML reader on your proxy.



var store = Ext.create (http://www.sencha.com/forum/#!/api/Ext-method-create)('Ext.data.Store (http://www.sencha.com/forum/#!/api/Ext.data.Store)', {
model: 'User',
proxy: {
type: 'ajax',
url : 'users.xml',
reader: {
type: 'xml',
record: 'user'
}
}
});

Sorry but than how the Form Result function will work because from what I understood unless we supply "Success" or "Failure" to success : function(form, action) the function doesn't allow any processing.

I am now thinking to change my response to JSON ,can you reply what should be my JSON reply.

Thanks,
Shehul

The success property on your result is optional. If you return an HttpStatusCode of 200 then your success callback will be called.

Hi Gurufaction,

Consider me as a newbie to everything, so can you please reply how to set HttpStatusCode to 200? and what to send in case of error?

Thanks,

Any response generated by your ASP.NET code should be status code 200 by default. If you wan't to handle any errors you can format your results to include a success property or just change the http headers on your response.
