I think the problem is that the generic HtmlHelper<TModel> class is not covariant. Therefore, you can't cast an instance of HtmlHelper<List<Product>> to HtmlHelper<IEnumerable<Product>>.
In this case, the model parameter will be the same type as the Model - ie: List<Product> - so you'll need to use FirstOrDefault in the lambda expression:
@Html.DisplayNameFor(model => model.FirstOrDefault().name)

One more question. Why here
@Html.DisplayNameFor(model => model.name)
The title (e.g. "Name") of the property is printed on my web page instead of value of property?
|
|
|
|
|
Because you're using DisplayNameFor. When you want to display the value, you use DisplayFor.

inconvenient and confusing syntax overall, I would say.

Hello All,
Kindly let me know what is the alternative of VSFlexgrid activex control in asp.net mvc.
VSFlexgrid as per my knowledge behaves like in left panel it is tree and in right panel it is grid with excel like column which are used to edit within itself.
Thanx in advance

I haven't heard or seen the word activeX in over a decade.
I think these were for VB6 and older windows programs, and do not apply to asp.net.
In asp.net, it's called the gridview.

I am a newbie in this.
actually the control is in old asp work , where there was a control called VSflexgrid as far as my knowledge is concerned on this.
Even i may be wrong.
But the functionality of the control is as such.
1) in left panel it shows treeview and in right panel it shows excel like cells in grid format.
2)These excel like cells do have different events associated with them like on typing something in the individual cell on mouseout the cell value get display to some another control.
3)the treeview and excel grid are collapsible, means the treeview node gets collapse like the adjacent rows of excel grid also gets collapsed.
I hope this can be understandable.
Based on this please kindly suggest me this functionality is achievable into the Asp.net MVC.

Currently, there is a Treeview control and a Gridview control.
So you use the Treeview on the left, and the Gridview on the right.
But I have used the treeview several times in the past, and don't recommend it unless you really need it. I used it in code behind, and it's one of the most undocumented and hard to understand controls that I have ever used besides the report writer.
Today, asp.net is Web stuff
vb.net is windows programming in Visual Basic
c#.net is windows programming in cSharp.
ocx or activex controls go back to Visual Basic in 2003 and prior, back when there was Visual FoxPro and so forth.

Thanx for your reply .
but i want this behaviour to be used in sync with each other.
so is there any control with both the functionality in a single control.

We maked login page then click login go to other page ok
after that like gmail if we changed url then dont go to home page and dont go to back so simple i want to need code
can u send me
|

Once you navigate the user off the website, you can't really go back, since you don't control the other website.
The back button works because they have a cache of web urls, and web pages that they load when you click the back button.
Your idea is a really bad one, poor design.

Deal with the error so you can handle it gracefully.
|
|
|
|
|
What error are you getting?
|
|
|
|
|
What is the error you get there.
or it's browser's functionality which cache the data for a while may be.
delete the browsing history.
or if possibility there could be a trouble with the session management.
try these options for checking .

Mr. Relevant,
I would like the support of relevant experts about the problem you are precious and I could not reach a conclusion on the long-term efforts.
The problem is that the checkbox to add a page I created on my autopostback asp.net I determine the true characteristic of a div block that displays true or false depending on whether or no to being normal.
The TextBox control is hooked into another RequiredFieldValidator control to prevent left blank.
I have seen pages that run had I autopostback work and did the research I've seen enableeventvalidatio the feature pages of this issue will be resolved by making false and I saw him try when autopostback try now but did not work RequiredFieldValidator control at this time. When I do enableeventvalidatio control true this time autopostback does not work, RequiredFieldValidator control started working.
The resources bulamadım.ilgil clear information when you search for the relevant foreign welcome.
I wish you good work.

is it possible for gridview to filter data based on input from a textbox like with listview in desktop app
|
|
|
|
|
Rather than getting the gridview to filter your data, you should filter the data yourself before you bind it to the gridview. Binding your data via code-behind rather than aspx markup gives you greater flexibility about how you bind data.
