View 1 RepliesI want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

I am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this
[Code]....
and then in the function I have no idea how to pass the values:

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
