Html.Display does not work with ViewBag.
#Html.Display("disp", (string)#ViewBag.disp)
I must use this viewbag because it can be modified by a search button selecting another disp.
#Html.TextBox("disp", (string)#ViewBag.disp)
If I use TextBox instead of Display it works, but I want to be read-only. How it is possible?
Because there's no overload of Display which takes a value as argument.
So.
You can simply do
#ViewBag.disp
or (if it contains HTMl)
#Html.Raw(ViewBag.disp)
or if you want a TextBox
#Html.TextBox("disp", (string)#ViewBag.disp, new{#readonly = true})

I want to set the value of a text box to a ViewBag item. Why doesn't the code below work?
#Html.TextBox("UName", #ViewBag.UName)
#Html.TextBox("UName", (string)ViewBag.UName)
So normally I am doing something like this:
#Html.EditorFor(m => m.MyDateTime)
Then I have a custom template DateTime.cshtml that is used as the editor.
Whatever the date value of Model.MyDateTime is will be displayed as expected, and as expected the name of the field on the next POST will be MyDateTime.
My desire is to use the custom template in the Html.EditorFor WITHOUT binding in the model object, instead I wish to give it a form field name to be POSTed but have it start out blank.
However I can't find an override of Html.EditorFor() that will allow me to not specify a model object, so I can only specify the template to use and the html form field name so it starts empty.
Note: I tried #Html.EditorForModel("DateTime", "MyDateTime") but just got an error so I think that I misunderstood what that is for.
(I know I could just have MyDateTime be null coming back from the controller but that is not what I am asking here.)
Why would you want to use an EditFor that is going to edit nothing (no model passed)? Instead of going down that road, you should probably look at using a View or PartialView which do not require having a Strongly-Typed model.
I would like to pass the file name of a partial view as data retrieved from the viewbag as such:
<div id="Zone1">#Html.Partial(ViewBag.ZoneControl1)</div>
Where the "ZoneControl1" property of the ViewBag is the name of the desired partial view retrieved from elsewhere (i.e. database, web service, etc.). If I include the text as a literal string i.e.:
<div id="Zone1">#Html.Partial("Controls/MyPartial")</div>
It works just fine. If I pass that literal string as a property of the ViewBag from the controller, or even just create a variable in the consuming view, i.e.:
#{string zone1 = "Controls/MyPartial";}
<div id="Zone1">#Html.Partial(zone1)</div>
It doesn't work. The page appears to be loading but never displays anything in the browser. Again, this works fine if I hardcode the partial view name, but not if it is passed as data from a variable or property. Anyone know why this is happening? If this is intended or unavoidable behavior, is there a workaround?
You can't use dynamic in Html.Partial (which is what ViewBag is) because it accepts only strings. One quick way around this would be to cast your ViewBag.ZoneControl:
#Html.Partial((string)ViewBag.ZoneControl1)
As for the second part (zone1 = "Controls/MyPartial") I was unable to duplicate that.
The following code is what I wrote to test it and it works just fine.
#{ string zone1 = "Controls/MyPartial"; }
<div>#Html.Partial(zone1)</div>
I assume the answer with casting the ViewBag is what you're really looking for in this case.
Well, I have it working now and I'm not exactly sure what fixed it. I copied the razor code\markup and deleted that view and created a new view and pasted in the old code. The only difference was that when I created the new view, via the wizard, I specified to NOT use a master page and the resulting page had code to specify:
#{
Layout = null;
}
The original page was created using a master page and then I changed my mind and took out the layout directive entirely. Anyway, after making those changes, it WORKED! So, I initially surmised that the reason was that a view must specify "layout = null" if not using a master page. BUT, I then took out the "layout = null" code in this new page and it still worked! So... not sure what went wrong, but to sum up:
As #BuildStarted correctly noted, you can use a property of the ViewBag object as the partial view path, but you must cast it as a string for it to work properly. So, the premise for this question was incorrect and something else was mucking things up. Just not sure what.
I have the following partial view which renders a drop down list:
#model MartinDog.Core.Models.Section
#{
#Html.DropDownListFor(x=>x.Name
, new SelectList(Model.Dock.DockTemplate.Columns,
"Id", "FriendlyName",
Model.DockTemplateColumn.Id.ToString())
, new { #id = "ddlb_dockTemplateColumns" +
Model.Id.ToString()})
}
I render it on my page like so:
#{Html.RenderPartial("_Admin_Page_DockTemplateColumnDropDown", Model);}
The partial view is rendered once for every Section object. A Section object one I've created and is editable in a jquery dialog box (change the name, display order, dock template column, etc.)
On the test page I am using, this Section dialog box is rendered four times (as there are four of them in my parent object).
The problem:
*The SelectedValue in the SelectList for the drop down never gets set* - that is to say, the correct item in the drop down list is never selected when the dialog is displayed and I can't quite work out why.
I thought it might be because the drop down is rendered four times, so I tried rendering it for just one of the 'Sections' but still the same problem.
Anyone know what I can do?
***edit
Not sure if I'm doing it in a sucky way. I had thought of building the dialog just once with jquery and json but I'd prefer to do it this way as it just feels cleaner.
I do this:
In controller action (Edit for example):
ViewData["ProvinceID"] = new SelectList(dc.Provinces.OrderBy(p => p.NameAr), "ID", "NameAr", factory.ProvinceID);
and Markup:
<%: Html.DropDownList("ProvinceID") %>
See? so it is a list of factories and it has a Province field and what I want you to notice is the 4th parameter in the SelectList constructor, I passed factory.ProvinceID so the DropDownList knows which option to be set on. Otherwise the DropDownList will show the default value (the first one).
P.S: It is your job to change to Razor syntax; I don't use it.
Hope that helps.
Doh... fixed - totally my own fault.
I had set up my html.dropdownlistfor like so
#Html.DropDownListFor(x=>x.Name,
When it should've been like so:
#Html.DropDownListFor(x=>x.DockTemplateColumn.Id,
Setting the first argument to x=>x.DockTemplateColumn.Id (which uniquely identifies the items in my list) instead of x.Name fixed the issue straight away.
Just thought I'd post it here in case someone else makes the same mistake I did.

Found the answer here:
C# mvc 3 using selectlist with selected value in view
I am trying to select a link/button inside of a form, that is in a div. the way it was made is that there are two links/buttons of the same id, name etc. however they are in different forms, so the code i wanted to use is:
_myTest.Form(Find.ById("PermissionsForm")).Child(Find.ByClass("saveBtn")).Child(Find.ByText("SAVE"));
any help would be appreciated
I think this is what you need:
var button = _myTest.Form("PermissionsForm").Button(Find.ByClass("saveBtn"));
This will lookup the button having the class 'saveBtn' inside the form 'permissionsform' in your browser instance _myTest.
Have a look at this page to decide if you need to have .Button(..) or .Link(...) based on the html tag that is used in your html.
How about building a regex for the element?
Regex could something like this
Regex elementRe = new Regex("id=LnkOk href="http://stackoverflow.com");
Then you can use your code to Click this link. The Click method can be extended to accept Regex if it is not already doing that.
Let me know how this goes or if you need more info.
Cheers,
