Updating ViewModel values on HttpPost

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
 
Hi there, I am just getting started with MVC after many years of WebForms development. I am struggling with some basics that I hope you can help out with. I have a very simple page with two textbox fields, one called Input where a user will enter something, and one called Output where I want to return some string after they post the form, much like a postback scenario in WebForms. I have the View connected to a ViewModel for strong typing. The ViewModel: public class TestViewModel { public string Input { get; set; } public string Output { get; set; } } The View: <% Html.BeginForm(); %> <%: Html.TextBoxFor(x => x.Input) %> <input type="submit" value="Submit" /> <br /><br /> <%: Html.TextAreaFor(x => x.Output)%> <% Html.EndForm(); %>   The Controller: public ActionResult Test() { var viewModel = new TestViewModel(); viewModel.Input = "Enter something"; return View("Test",viewModel); } [HttpPost] public ActionResult Test(TestViewModel viewModel) { viewModel.Output = "Here is some response"; return View("Test", viewModel); } The problem I have is that the

Help with updating database with values from Repeater control using c#

  

Hello, I'm new to ASP.NET 3.5 with C#. I really need some help.

I used a Repeater control to create a simple (editable) list where, when a user logs in, they can edit their list of expenses.  The ASP page works fine.

 My issue is with the code-behind.  I am really confused with how to extract the values from the repeater control. The FindControl method does not seem to be working.  Also, the code I am using resets my 'Amount' values back to 0.00. (0.00 is the amount the user sees when they first encounter the page).

 Here's a portion of the code on the ASP page:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"

            onitemcommand="Repeater1_ItemCommand">

.

<ItemTemplate>

.

<td><asp:Label ID="lblExpId" runat="server"  Text='<%# Bind("ExpId") %>'></asp:Label> </td>

 <td><asp:Textbox ID="lblExpense" runat="server" Width= "190px" Text='<%# Bind("ExpenseName") %>'></asp:Textbox> </td>

 <td><asp:Textbox ID="txtAmount" runat="server" Width= "100px"

Updating list item values in SharePoint Designer using code

  
Is it possible to programmatically modify the SharePoint objects using SharePoint Designer Object Model. By that I mean coding in SharePoint Designer (not Visual Studio). For example, can we access the list items of a list programmatically and change their values? I can do all this in Visual Studio using SharePoint Object Model but I don’t find a way of achieving this by using programming in SharePoint Designer. I searched through http://msdn.microsoft.com/en-us/library/bb208639(office.12).aspx but no success. If the answer is yes. Can someone please give example(s) or point to some articles etc? Thanks in advance.

Row cannot be located for updating. Some values may have been changed since it was last read

  

hi SharePoint Gurus,

I am deeply stuck with one issue

Description Infopatth 2007/2003: InfoPath cannot submit the form. An error occurred while the form was being submitted. Row cannot be located for updating. Some values may have been changed since it was last read

This is really frustating me as this happens only some time where as other time it is working fine. My questions are :-

1) On How to re-produce this error? Because re-produce means it can be resolved as well hopefully?

2) Secondly the possible permanent solution to this.

I have search on google & bing with no feasible solution as yet. The thread below mentioned something which doesn't help me at all.

Dialogs and ViewModel - Using Tasks as a Pattern

  
The ViewModel/MVVM pattern continues to gain popularity, with a blog post showing up every so often, and with tweets and retweets popping up even more often :-). At the same time, there are some interesting topics beyond the core pattern that continue to fuel experimentation. A big one amongst those is how should applications use dialogs when using the view model pattern.

The crux of the problem is the desire to keep the view model independent of UI concerns, and ensure it can be tested in a standalone manner, but that often comes to odds when you want the view model to launch a dialog, and/or do some work after the dialog is closed.

A Generic Dialog ViewModel

  
I worked on a wpf viewmodel for dialogs, because it seemed strange to me that you needed for instance windows forms dialogs to open or save files in wpf. So I set about creating my own wpf dialogs. After creating the dialog viewmodels there still remained a small issue with the library and also I didn't have much time to write an article about it. I however published the library containing the viewmodels for dialogs with another article on my blog

How to Pass Values Between Web Pages ASP.NET

  
You can pass information between pages in various ways, some of which depend on how the redirection occurs. The following options are available even if the source page is in a different ASP.NET Web application from the target page, or if the source page is not an ASP.NET Web page:

Use a query string.

Get HTTP POST information from the source page.

The following options are available only when the source and target pages are in the same ASP.NET Web application.

Use session state.

Create public properties in the source page and access the property values in the target page.

Get control information in the target page from controls in the source page.

JQGrid Loading deleted values

  

Hi,

This is quite strange. here is the issue:

Some Info:

1. I'm using a multi-select jqgrid.

2. I have my own delete button to delete multiple orders

The problem:

When i press the delete button on the pager of my jqgrid, the records are deleted from the database but JqGrid shows some records (4-5). On refreshing the grid, correct numbers of records are shown.


Here is the code:


function delorder() {
        var amg = $("#horder").getGridParam('selarrrow');
        var cont = amg.length;
        if (amg.length > 0) {

Error when updating. Supposedly updating ID without being asked.

  

 

Server Error in '/' Application.

Value of member 'ID' of an object of type 'Ref' changed.
A member defining the identity of the object cannot be changed.
Consider adding a new object with new identity and deleting the existing one instead.

I get this error whenever I attempt to update an entry. Even an entry that has had nothing altered. I have tried to circumvent it but I think it must be a simple oversight. How could I have caused an ID update using the Edit.aspx page of dynamic data? Thank you in advance for the help!


How to cast integer values as an array of enum values?

  

Hello all!

I'm working with VS2010 Beta2, ASP.NET and Dynamic Data. I'm using VB but will certainly be happy to receive a C# example if necessary. Laughing

I used a few of Steve's examples (Writing Attributes and Extension Methods for Dynamic Data and Dynamic Data - Hiding Columns in selected PageTemplates) to create a custom property attribute to be applied to a dynamic data column and want it to accept an array of enum values (each value will represent a dynamic data page template where this column should not be displayed).  My new attribute works fine when I hardcode it like this, meaning the HideColumnIn attribute is properly populated with the array of enum values:

<HideColumnIn(PageTemplate.List, PageTemplate.Edit)> _
Public Property My_DD_Column As Object

 

However, I want to store the values to be used for the HideColumnIn in the DB as integer values that correspond to the

Retreiving XML tag values

  

Hi,


I'm new to xml.


Currently I'm using the SOAP service and MSXML2.ServerXMLHTTP40  to get data from a website.

To retrieve data I'm using the "responseText" method of the MSXML2.ServerXMLHTTP40 class.


My XML tree looks like this. ( part of the tree)


<dataID>0</dataID>
<projectName>100208_FC3_BY_RO_rza</projectName>
<chunkSize>0</chunkSize>
<minLat>47.8512912</minLat>

<audioCount>0</audioCount>
<gpsCount>84475</gpsCount>
<mcvCount>2475</mcvCount>

</JobInfo>


Just need to retrieve the value of the "projectName" & "dataID" from this.

Appreciate if somebody can help me to get the values of the above 2 fields with the relevant code.


Thanking you in advance.


reading values from config files in NUnit tests

  

One of my NUnit tests has to read in some values from config files.  In my main application this process works perfectly well, however when I run the unit test, the code that reads in the values from the config files doesnt read anything in.  Ive tried putting app.config in my unit test project (I even tried web.config) but nothing seems to work.  Are there any special steps involved when reading from config files in an nunit test ?
