I'm new in ASP.NET MVC 2 and I'd like to write a very simple dropdown list which gives static options. For example I'd like to provide choices between "Red", "Blue", and "Green".
View 2 RepliesI have small design question about
html.DropDownListFor()
How can i change width of html.DropDownListFor() ??
For example by css.
I have the following code:
[Code]....
However, the wrong option is selected, and when I view page source, it renders like this:
[Code]....
Why is this occurring?
I am looking at ASP.NET MVC2 and trying to post a complex object using the new EditorFor syntax.I have a FraudDto object that has a FraudCategory child object and I want to set this object from the values that are posted from the form.Posting a simple object is not a problem but I am struggling with how to handle complex objects with child objects.I have the following parent FraudDto object whcih I am binding to on the form:
public class FraudDto
{
public FraudCategoryDto FraudCategory { get; set; }

Learning about dropdown lists, Im trying to add a RSVP create page for nerddinner as in Scott Gu's blog with a Html.DropDownListFor listing available dinners. I can get the dropdown list populated but I cannot get the dropdown to pre select the value ("Sample Dinner 2") I want. Im using an initilizer to seed a few dinner objects in the db. The database is sql ce 4 using a EF 'code first approach'. Sorry I know this is a v common problem and hate to ask, but honestly have spent quite some time on this but cant get it to work:
ViewModel
public class RSVPViewModel
{
public SelectList DinnersList { get; set; }
public RSVP Rsvp { get; set; }
public string SelectedItem { get; set; }
}
[code]...
So is not preselecting the dropdownlist with the value "Sample Dinner 2" when the page loads. The list displays ok and sets the correct DinnerID when I make a selection and click Submit.Tries this also:
@Html.DropDownListFor(x => x.SelectedItem, Model.DinnersList)
but doesnt set or bind to Rsvp.DinnerID.This preselects from the list but doesnt bind (or set Rsvp.DinnerID)
@Html.DropDownList("DinnersList")
I want to keep it mvc3 so want to implement with strong type using ViewModel approach (no ViewData) and preferably using Html.DropDownListFor (not Html.DropDownList).Viewbag seems unnecessary for this case.Thinking I should be using a selectList of selectListItems I tried this verbose approach :
RSVP rsvp = new RSVP();
string selected = "2";
List<SelectListItem> dinners = new List<SelectListItem>();
foreach (Dinner dinner in dbc.Dinners.ToList())
{
SelectListItem slDinner = new SelectListItem();
slDinner.Value = dinner.DinnerID.ToString();
slDinner.Text = dinner.Title;
slDinner.Selected = (slDinner.Value == selected);
dinners.Add(slDinner);
}
var dinnersList = new SelectList(dinners, "Value", "Text", selected);
var viewModel = new RSVPViewModel { DinnersList = dinnersList, Rsvp = rsvp, SelectedItem = selected };
However still no work. Should I be making use of the ViewModel SelectedItem property in: @Html.DropDownListFor.. somehow? Something like :@Html.DropDownListFor(x => x.SelectedItem, Model.DinnersList)but how to I get a selected value to set Rsvp.DinnerID. I think thats called binding.

Rather than try to reinvent the wheel, how to create a stacked/segmented bar or point me to an existing control. Here's what I need:
Horizontal bar
Standard html
Each segment needs to be color coded from css
Each segment needs to be a percentage of the total (i.e. if total value = 100, then a value of 10 for one of the segments would be smaller than a value of 50)
Should be able to fit seamlessly into an html table cell
Should not be an image
Should only create a single bar with segments (not multiple bars/segmented bars)
Server-side generated, no AJAX
This should be as simple as possible given x number of values, create x segments.
I'm looking for code examples or already-built controls.
EDIT: For completeness:
int[] segments = { 10, 5, 45, 20, 20 };
Panel horizontalBar = new Panel();
for(int segmentIndex = 0; segmentIndex < segments.Length; ++ segmentIndex)
{
horizontalBar.Controls.Add(new Panel() { ID = String.Format("segment-{0}", segmentIndex), Width = Unit.Percentage(segments[segmentIndex]), CssClass = "segment" });
}
this.Page.Form.Controls.Add(horizontalBar);
how to convert simple html to .net control
[Code]....
I am using my webcontrols widely in application, but I would like to know if it is possible to get rid of usage of <tagprefix:tagname id='' runat='server' /> construction and register control as HTML control instead.
For instance: Control MySpecialButton. The usual way to use it is: <uc:MySpecialButton ID='msb1' runat='server' Property1='Custom property1' Property2='Custom property2' />
I would like to change its appearance in HTML as following: <MySpecialButton Property1='Custom property1' Property2='Custom property2'>. Just for it to look like very simple HTML tag.
I have this simple html page that talks to a microchip. It turns a LED light on and off.

Can someone give me some pointers on how to convert the above to asp.net. I have put two asp:buttons on a webForm. Then for the button clickevent of the btnOn would I use something this like this? Or is WebRequest the wrong concept to use? I can seem to get this code to work for me!

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.

How about adding a helper that will create a simple HTML editor, like the one I am using to write this post? That would be completely awesome, and would just about make this good little tool a GREAT tool.

I have a table, and each row has a column where its data is actually a select list. I want the user to be able to select a drop down item, and when they POST, it saves the Id of the selected item. Is this possible?

I don't know how to retrieve a DropDownListFor value on form post and how to validate it.
This is my scenario:
HTML markup:

otherwise I get an "object reference not set" error on post-back.
I use the Entity Framework and Linq to Entities with MVC 2.0. When use the DropDownListFor from Html helpers to populate a dropdown that contains an ID from a foreign object, I post the form data but I canīt set the correct relation. Using the debug, I can see the ID retrieved from dropdown at my returned foreign object ID, but I think that I not use the association correctly.
View 4 RepliesI have a textbox on my aspx page defined as:
<input name= tbdisplay type="text">
I can pick the data (I built a touch screen keyboard and I used javascript to write to the thextbox) from code behind using:
string textdisplaydata = this.Request.Form.Get("tbdisplay");
But I can't figure out the way to write back to the same display from code behind. In other words, I need to send a message back to the textbox from code behind. Because I did not defined the tbdisplay to runat="server", I can't see the control tbdisplay. Also, I can't run the tbdisplay at server because the keyboard doesn't work.
