How do I do 'ModelMetadata.FromLambdaExpression(x => x.Books[0], ViewData)' with FromStringExpression?
I tried 'ModelMetadata.FromStringExpression("Books[0]", ViewData)' but it seems it doesn't understand index notation.
I build a gridview View with a generic model type, because the actual model can be anything.
My model is of type: IModelContainer<IModel>
And the definition of that interface is:
[Code]....
In my grid.cshtml i need to get all the propertynames to use as columnheader, but i do not know them beforehand.
I use the following code :
[Code]....
This works perfectly when there is at least 1 row in the Items list, but how do i get propertynames, when there is no data?
I can get the typeof the actual class implementing the IModel interface via a property on my IModelContainer interface if needed, but i don't know how to go from there.
[Code]....
[Code]....
How can i get full name of the property ?
Is it possible to change Properties of ViewData.ModelMetadata in Controller?. For example, can I do the following to change the display information of the LogOnModel:
[Code]....
When I do that there is no errors but DisplayName is not change. I'm trying to localize strings to different languages and also to make some attributes of the model different depending on users roles.
After upgrading to MVC 3 RTM I get an exception where it previously worked.
Here is the scenario. I have several objects that use the same underlying interfaces IActivity and IOwned.
IActivity implements IOwned (another interface)

I'm working on a project where we're using Windows Desktop Search (WDS) to index files on a web share and then later allow the user to search via a website for documents in the share.
These documents are transferred to the share via FTP, however it would seem that either the computer never goes idle to index or at some point the indexing stops. Is there a way from the command line or within the program itself to force this to happen without having to re-invent the wheel? Using .NET 3.5 and C#.
Here is my code in SQL

Error i am facing is :
Msg 8668, Level 16, State 0, Line 2
Cannot create the clustered index 'RateViewIndex' on view 'NoteToPass.dbo.RateView' because the select list of the view contains an expression on result of aggregate function or grouping column. Consider removing expression on result of aggregate function or grouping column from select list.
what is difference in cluster index and noncluster index?
which is faster?how many cluster index and non cluster index per table?
what is composite primary key?on how many columns we can create composite key?
hao many maximum composite key's we can create on one table?
I have two control page in my aspx page. first one left side "tree view",second one right side " form design".Form design will change based on tree view selected index changed.i have 4 level child node(site, master , slave, space). I have seperate forms to each level of node.
cannot update tree node when update the forms. so i reload tree view.
now i need how to auto selected index change to tree node.
ex.
1 parent node
1.1 child node
1.2 child node
i have update "1.2 child node" rename to "1.3 child node"
and reload treeview so it will chage...
how set tree node.selected index = 1.3 child node....
gvOff.DataSource = o.ViewData(dCity.SelectedValue);
gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";
Header count is correct.
AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.
where should we use clustered index and non clustered index.i mean in day to day use which on e to choice and how to make decision.

I have a datalist with products we use on our product page. I'm generating javascript for each item in the collection using:
foreach (ProductItem item in _prod.ActiveProductItemCollection)
{
sb.Append("<script type='text/javascript'>");
sb.Append("mboxCreate("product_productpage_rec",");
}
and so on...
What I want to do is get the index of the item and append it in my stringbuilder. I'm learning asp.net and am not quite sure how to do it. Here is an example of how the code would generate ideally.
first product
<script type='text/javascript'>
mboxCreate("deandeluca_productpage_rec1")
</script>
second product
<script type='text/javascript'>
mboxCreate("deandeluca_productpage_rec2")

i am developing a site that composed of two parts. Admin and Web which way i must follow?
1- i will create a web site by MVC3 and create an area in it for admin.2- i will create two MVC project one of them will be Web other admin. and i will create two domain (mysite.com and admin.mysite.com)which way is professional.and i want to google must not index the admin site. how can i do this?
I've made the change from querystring asp.net webforms application to an url routing one. Now I'm trying to let google know that there's a new set of urls to be aware of. The G has indexed 133 out of 179 new urls sent in sitemap.xml, but the site:mistral.hr command returns the old querystring version of the links.
This could partly be so because I left the functionality of the old querystring version of the site(for backwards compatibility), and haven't done any 301 redirects(nor do I know how to achieve them in my shared hosting account).
The old querystring and the new url routing both point to the same Default.aspx page.
