MVC :: Bind Text Box To Model Property Not Working On "post Back"?

Jan 22, 2010

i have a text box that i bind to my model data and it works fine. however when i submit my form in some cases i want to change the value that in the text box so some value i pull from the db. when i do this, it only works if the form was not submitted. is there something i am not aware of when it comes to rebinding a text box from the model in cases when the form was submited, instead of reloading the same value that the user entered into the text box?

C# - MVC - Using Model Property As Form - Post To Action?

Jan 12, 2011

public class BandProfileModel
{
public BandModel Band { get; set; }
public IEnumerable<Relationship> Requests { get; set; }
}
and the following form:
<% using (Html.BeginForm()) { %>
<%: Html.EditorFor(m => m.Band) %>
<input type="submit" value="Save Band" />
<% } %>
which posts to the following action:
public ActionResult EditPost(BandProfileModel m, string band)
{
// stuff is done here, but m is null?
return View(m);
}

Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null). It's posting just fine to the action, so it isn't a problem with my route. Just the data is null.

The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work. What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action?

How To Bind Post Data With A Model That Contains Multiple Models

Nov 4, 2010

I have a parent View that uses a few partial views. Each partial view has its own custom model. The parent View is a model containing each of the partial view's model. In other words this parent View model is NOT flat.

How do i get POST data to bind with the parent's model object? Do i have to write a custom model binder?

Update I'm not binding to a collection of objects of the same type (ie: a collection of uploaded files). I'm binding to object that contains multiple of objects. For example:

MVC2 Model Binding Does Not POST Back Hidden Values?

Jul 25, 2010

I have a /Register [GET] Action in the controller that pre-poluates a view-model with a string and an integer and returns: return View(myModel);I can see the string being populated in the textarea and the id being populated in a hidden input. Yet when the form gets POSTed, the string value is null and the int value is 0. I verified that both values are posted to the server but the model received in the POST action is missing those values.

C# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?

Jul 14, 2010

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).

Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?

Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

How To Send Text Message Using JavaScript To Avoid Post Back

This is what I have implemented, for further code, how to send the text of the text box to the server to store in variable or database without post back? It can be done by using Ajax and update plane, but I would like to implement it using a JavaScript script.

<div id="CommentID" style=" width:30%; height:30%">
<asp:Button ID="Button1" runat="server"
Text="Comment"
OnClientClick="visibleDiv('id1'); return false;" />
<div id="id1" runat="server" style="visibility: hidden; background-color:Green; width:100%; height:100%">
<asp:TextBox ID="TextBox1" runat="server"

How To Bind Form Collection Back To Custom Model Object That Uses 2 Custom Objects

Mar 23, 2010

What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....

The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.

public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.

For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.

Web Form And Ajax Data Lost On Post Back - Finding Possible Cause / Ajax Or Changing Visible Property

Sep 15, 2010

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.

The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.

Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.

However, when the Submit button is clicked, the Repeater control contains no data.

Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.

The User Controls are contained within the UpdatePanel that contains the Submit Button.

I have explicitly Enabled View state without any effect.

Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?

I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).

I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).

Forms Data Controls :: Conditionally Bind Text Property Of DropDownList

[Code]....

I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.

Web Forms :: Make Sure Hitting Enter On The Page In Any Other Text Box Doesn't Post Back To SearchPage.aspx?

Feb 28, 2010

I have a master page which includes a search textbox and a button which posts back to another page. The controls are defined as follows:

<asp:TextBox
ID="SearchTextBox"
runat="server"
style="margin-left:
0px"
Width="170px" />
<cc1:TextBoxWatermarkExtender
ID="SearchTextBox_TextBoxWatermarkExtender"
runat="server"
Enabled="True"
TargetControlID="SearchTextBox"
WatermarkCssClass="watermark"
WatermarkText="Search Name" />
<asp:Button
ID="SearchButton"
runat="server"
Text="Search"
PostBackUrl="~/SearchPage.aspx"/>

The problem is that for any other TextBox on the page which is using this MasterPage, for example the login page, if you type your user name and password and hit Enter, The page is redirected to the SearchPage. If you click on login buttton everything works fine. How do I make sure hitting enter on the page in any other text box does not post back to SearchPage.aspx?

Default Model Binder Does Not Bind Model Class

Dec 28, 2010

I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted

<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>

This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });

This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }

But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.
