ViewData["JobMeta"] = JobsMeta;
now using the view i want to loop through ViewData["JobMeta"]
<% foreach (var JobsMeta in ViewData["JobMeta"]))

I need to convert a SharePoint List to ASP.NET, including its column filters etc.
Aside from the underlying data which will be housed in a SQL Server table, what are good control choices on ASP.NET side for this? (I'm not sure if ASP.NET Gridview will have all the necessary features.)
List<string> IDs = new List<string>();
XDocument doc = XDocument.Parse(xmlFile);
var query = from c in doc.Root.Elements("a").Elements("b")
select new { ID = c.Element("val").Value};

I want to loop thru dropdown list and check the individual list item text using C#, let me know what is the best way to do this?
View 4 RepliesI am trying to assign values I've gathered from a JSON feed to my own type, a class in which I have defined certain fields (properties) to put the JSON elements into, plus elements that are derived from a RegEx pattern matching process. This will then allow me to access the object using LINQ, as I am using a List to hold my objects. There is a foreach loop in my code that loops for each match that my RegEx method finds. I am only interested in the parts of the JSON feed where there is a match. So my own defined class is as such:
//simple field definition class
public class TwitterCollection
{
public string origURL { get; set; }
public string txtDesc { get; set; }
public string imgURL { get; set; }
public string userName { get; set; }
public string createdAt { get; set; }
}
And then I want to populate List in the RegEx Matches loop:
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
var tc = new List<TwitterCollection>()
{
origURL = groups[0].Value.ToString(),
txtDesc = res.text,
imgUrl = res.profile_image_url,
userName = res.from_user_id,
createdAt = res.created_at,
};
}
The code will then go on to extract and sort the results via Linq to Objects. But compiler won't actually let me create my var tc = new List<TwitterCollection>() because: 'System.Collections.Generic.List' does not contain a definition for 'origURL' ... even though I have defined it. It does not flag an error if I simply write new TwitterCollection but then how do I refer to this in my Linq expression later on??
I have dropdown list I want to use the arror to click and control and select the value in the dropdown box , the first click select item1 .... How can I do that?
View 4 RepliesI am converting my datatable to LISt using LINQ how do I handle nulls coming from database
List<Port> portDetails = new List<Port>();
DataTable dt = ds.Tables[0];
portDetails = (from q in dt.AsEnumerable()
select new Port
{
PortCode = q.Field<string>("Code"),
ExtCode = q.Field<string>("Nb"),
Name = q.Field<string>("Name"))
}).ToList();
In the above query if Code is null I do not want property portcode to be set to the value it should only set if it is not null or not blank
PortCode = q.Field<string>("Code"),
What should be syntax
I was trying somethign like this which doesnt work
Portcode = q.Field<bool>("Code") == null ? null : q.Field<bool>("Code")
I've data which looks something like this.
[code]....
To convert the above data into unordered list based on depth, I'm using the following code
[code]...
But the resulting unordered list doesnt seem to be forming properly(using which i am constructing a tree).For example "Site " with id '180' is supposed to appear as a direct child of "Televisions" with id '1',is appearing as a direct child of 'Flash' with id '191' using my code.so in addition to considering depth,I've decided to consider itemid as well in order to get the treeview properly.Those rows of the table with itemId not equal to null are not supposed to have a child node(i.e.,they are the leaf nodes in the tree) and all the other nodes can have child nodes.
Update:
The 'itemid' column refers to the id of an item which is present in another table.This column just in identifying if an item has any sub items(i.e., 'name' in my data in this case has any other unordered lists under it).
How can I make the following code shorter and more efficient.

For Each CompanyRow In newdt.Rows

How can I get this to see the GetInfo as declared..... since its in a loop within a loop?

View 3 RepliesI have an issue with a Loop that doesn't actually loop. I've posted a simplified version of my code below. Basically, using the NPOI excel library, I have an excel file with data on the first and second sheet, so I need to do a loop to get through both sheets. Below is what I have done so far, however this only works through the first sheet and then exits. It fails to increment the variable w. As you can see, there are other loops implemented in this code which function fine so I don't get it.It's been a very long day and perhaps I'm missing something very simple. I could have it placed wrong or something. If anyone else can spot what I might be doing wrong I'd be very grateful :)
