MVC :: DropDownList Can Either Select Item OR Save Selected Item Back To Controller?

Jul 7, 2010

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

Database Table: This data has been imported using Link to SQL

Can HTML Element Into Form-data That Posts Back To The Server

Apr 24, 2010

I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value.

The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well.

I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?

C# - How To Select An Element By Class Instead Of ID

May 4, 2010

I have a few scattered <p> elements on the aspx page which I am grouping together using a class like so - <p class="instructions" runat="server">

In my code behind, using C# I want to hide these elements, using something like
instructions.Visible = false;

However I realize I can only do this in codebehind if I use ID but this will result in invalid HTML/CSS Selector since you can't have multiple ID's with the same ID name...

Alternatively is there another way to group the controls if not by class?

EDIT: I can't use JavaScript, so the selection must be done in C# codebehind/ASP.NET

Web Forms :: Client Validation Prevents AutoPostbacks On First Click Of AutoPostback Control?

May 4, 2010

I have an issue that I've been fighting with for some time. I have a large web form, with update panels and autopostback controls. When the users click "submit", some custom javascript runs which shows validation summaries and turns the fields with errors red, relatively easy, and it works as expected. The problem is that I have a dropdownlist which should autopostback an update panel. It does this perfectly if the user does not click the submit button, and therefore my custom client script dosesn't execute.However, if a user clicks submit, the custom client script executes (turns fields red and shows validation summaries), and then the dropdownlist does NOT autopostback the first time a user changes it's value. If the user changes the dropdownlist's value a second time, then the autopost back occurs and everything functions as it should. I don't understand why the autopostback is disabled for the first click after the javascript executes. Can someone please help me out? The DropDown List looks like:

[Code]....

The Submit button is:

Getting Value Of HTML Select Element On Form Post?

Mar 29, 2010

I have a View that has a select drop-down list and an edit button within a form. What I want to do is have the user select one of the options from the select element, click on the edit button, and get the value of the selected option in the Controller method.

I created my form with <% Html.BeginForm(): %>

and the Controller "Edit" method should be called.

I looked through several online examples, but each one focused on how to set values and the default selected value of the select element, rather than retrieving it from the code in the Controller method. I tried grabbing it from the Request.Form collection like:

string val = Request.Form["myDropDownList"].ToString();
and also:
string val = Request.Form["myDropDownList"];

Obviously I didn't do this correctly, because I get a null reference exception. Does anyone have the solution to this issue?

Add Class To Selected Option Of A Select Element

Nov 16, 2010

To demonstrate that I could even use a Class attribute on an option elem I tried adding class attributes to options of a select elem in a static page and that works fine. I noticed that not many online resouces documented this so I figured I would explicitly set the record.

here is the jquery code attempting to add a class to the selected option

[Code]....

New information, I found the reason nothing occured was a simple mistake in the value being passed in for compLev. However, now it runs through the code for the correct case and does nothing to the color of the item.

C# - How To Get Html.DropdownFor() To Select Current Element

Nov 11, 2010

I must be missing something simple here. This code was working and i can't seem to figure out why it stopped.

First, I generate a selectlist in the controller like this:

// Select List
ViewData["FieldTypesList"] = new SelectList(
genesisRepository.FieldTypes, "ftID", "ftName"
);

The View that uses this select list looks like this:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Genesis.Domain.Entities.Stream2FieldTypes>" %>
<%@ Import Namespace="Genesis.Domain.Entities" %>
<%: Html.DropDownListFor(
model => model.FieldTypeID,
(SelectList)ViewData["FieldTypesList"]
)%>
<%:Model.FieldTypeID.ToString() %>

However... the HTML that gets generated shows this:

<select id="Stream2FieldTypes_0_" name="Stream2FieldTypes[0]"><option value="1">Text Area</option>
<option value="2">Text Box</option>
<option value="3">Rich Text</option>
<option value="4">Image</option>
<option value="5">DateTime</option>
<option value="6">Decimal</option>
<option value="7">Integer</option>
</select>
3 <!--FYI: current value-->

I am completely missing why the view does not render html that selects 3 (Rich Text).

Web Forms :: Why Simple HTML Select Element Has A Misplaced Focus

May 13, 2010

This was generated from my asp.net page. (ListBox was rendered as select element)

I was able to isolate the focus problem from the ListBox to the following HTML.

Just copy-paste the HTML bellow and open it in a browser window.

The browser renders the Focus in a strange way. I have to solve it for one of our clients.

If the Height is set to 185px the focus doesn't work properly. I tried to play around with different heights.

Btw, if the Height is set to 81px there's no problem with the Focus.

But I have to have the height at least 170px.

AJAX :: Implement Live Binding - Purely Imperative Way - Combobox (select Element) Becomes Null

Jul 15, 2010

I'm trying to implement live binding, purely imperatively . In my example , I have a master view , which is populated using json array. In the detail view ,I'm just setting the value of a prepopulated combo box . But , the moment the bind statement is executed, the combobox (select element) becomes null. This works perfectly when done declaratively. Below is the code for imperative binding. This function is triggered when an item in the masterview is selected.

function execCommand(sender, args) {
// Create dataview for details section
var detailsView = $create(Sys.UI.DataView, null, null, null, $get("div2"));
$get("div2").className = "sys-template";
// bind the dataview to the selected data from the master
var b = Sys.bind(detailsView, "data", sender, "selectedData");
// after the above line of code is executed, the select element with id "myselect" becomes null.
//alert($get("myselect"));
// bind the value attribute of the combo box to the "Description" property of the binded data
var x = Sys.bind($get("myselect"), "sys:value", detailsView.get_data(), "Description");
//hence when the above line of code is executed , nothing happens :( ,i.e the value of the combo box doesn't get set
// alert($get("myselect"));
}

JQuery - Change Event On Select-element Getting Fired Twice When Using Both DOM-event?

Jun 17, 2010

There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:

<html>

<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....

This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
