View 5 RepliesForms Data Controls :: Looping Through Rows Of A Gridview Via The Datasource?
Mar 2, 2011I have a Gridview that has Paging enabled, and I need to loop through all the rows of the data. Therefore, I assume I need to loop through the datasource instead of through the Gridview.
I change the datasource of my gridview at various times when running.
How can I get a DataView of the GridView's current DataSource, so that I can loop through it?
Something like:
Dim dv as DataView = DirectCast(GridView1.DataSource, DataView)
except that this comes back as Nothing, probably because a Datasource isn't a dataview.
Forms Data Controls :: Looping Through Gridview Calling Visible False Cells?
Jan 10, 2010I have a gridview that serves as a confirmation for user input in a previous form from a previous page. The grid is databound to a temporary table where I store the user's initial selections. The user can confirm what they had submitted, (which may be more than one row of information, up to three classes) or go back and change. When they hit the confirm button, I loop through the gridview and enter a row in a permanent database for each row in the gridview. This works great.
However, I don't want the gridview to display all of the columns that are actually in the temp database, because I'm carrying over 'usersubmitted, datesubmitted', etc, from the previous page for each class selected and this is redundant. (I do need to use all of the columns when they submit, however, to make a new row with complete information for each selected class in the permanent database) So, when I set the usersubmitted column visible false, for example, in the gridview, the dataset table adapter insert function fails with a data type mismatch error. I'm assuming becuase the column has to be visible, becuase when I make it visible again it works.
Can you loop through a gridview and call on cells in columns that are not visible?
The first page is like this:
the user fills out his info once in text boxes
name ____
address____
then selects up to three classes in dropdowns:
class one dropdown ...
class two dropdown....
for each dropdown, I insert name, address, class selected into a temp db Second page.
Gridview should display only classes selected, one row for each, and not
name address class selected
name address class selected
then when they submit, I insert
name address class selected
name address class selected
one row for each in permanant database

Forms Data Controls :: Linq To Sql And Gridview Control?
Aug 11, 2010I recently created another post (http://forums.asp.net/t/1589122.aspx) that I now realize was barking up the wrong tree... I have a better idea of of the 'ball park' my issue is really in now... in the past, I have used a sqlDataSource control to bind data to a gridview, in which case paging and bidirectional sorting are truly an 'automatic' feature. However, now I am using linq to sql directly to bind data to a gridview, so not only do I need to handle my own paging and sorting, how youdo it is different.... I think I need to actually re-run the linq to sql query on every sort or page action..? well, not sure, that's why I'm posting this. What do I need to do?I'm also wondering if what I will need to do to implement paging/sorting is complex enough that I mind as well be looking into how to implement 'efficient' paging and sorting, as in only actually returning the subset of records that should be displayed?I need some guidance, specifically on paging and bidirectional sorting a gridview control, when the data is being retrieved from linq to sql queries... no datasourceControl
View 3 RepliesForms Data Controls :: DataSet And Looping Through Rows / Display Job Vacancies By The Result Of A DropDownList Value?
Jul 14, 2010I am having a problem with this code, i had a post on this however this code is slightly different to that so i thought i would post a spearate thread.
Anyway, what i am trying to do is display job vacancies by the result of a DropDownList value. Now each job name has a description. The problem i am having is i need to display the results in this logic:
Job nameJob descriptionJob location. But what is happening is the job description (body) is repeating the more vacancies there are. This is the page:
http://kidsunlimited.co.uk/vacancies_test_two.aspx
If you select Deputy Nursery Manager from the DropDown and hit the Search button you will see the results. After listing the first two locations the description is repeated and then the 3rd location is shown after this. This is my code:
