I have added a multiview and menu in a web page. I have 2 views. In both the views, i have added 2 dropdownbox. Two different Dropdown box is available in both the views. Dropdownbox are filled from the database.In the first view, i selected a data in the dropdownbox, and moved to the next view. In the second view, i selected a data in the dropdownbox. I clicked on the first menu, and in the dropdownnbox i am not able to retain the selected data. It is going to the default value.
I need a way to change the ActiveViewIndex of a multiview control based on some query results. Right now I test to see if I have rows returned from my linq query. If so, set a certain view active. If no rows are returned, I would like to set a different view active. I would like to do this on Page_Load if possible.
Right now I get the fatal "Object reference not set to an instance of an object" error on page load with it bombing at line 12. My count is given a value at runtime so that is not the issue. Can anybody tell me why this is and how to get around it. Code is attached.
I also tried this both the pre render and Page_Init event but both yielded the same behavior with the Object reference not set to an instance of an object error. I can do this just fine in an onclick event for a button, but now I need a way to run a test and set the default view when the page loads. Seecode below
protected void Page_Load(object sender, EventArgs e) { eCrystalPSGDBDataContext psgDB = new eCrystalPSGDBDataContext(); int count = (from st in psgDB.studyTbls where st.patientid_i == Convert.ToInt32(Request.QueryString["PatientId"]) && st.studystatusid_i == 1 select st).Count();if (count == 0)else if (count == 0) { StudyInfoMultiView.ActiveViewIndex = 1; } else { StudyInfoMultiView.ActiveViewIndex = 2; } }

i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.
On the HTML code is rendered only the first view or the view that is activated on page load.
Is there any way to find a control inside the view using javascript? or I am doing something wrong?
I have a web app that works with an object-relational database. Displaying data in a gridview is one thing, but when it comes to updating that data that is quite difficult with nested tables, user-defined objects, etc (I've had errors such as"Reference to a NULL table value", and a couple of things). My fix to this was to update the data on another page. '(This method involved using textboxes and a button, no detailsview or gridview).
So I'd like to know how do I select a row of a gridview in page 1 and that row displayed on page 2 for editing? I followed the steps here: http://forums.asp.net/p/1122208/1755008.aspx#1755008 and got the error "Object reference not set to an instance of an object."
This task seems pretty simple, but I don't know how to do it.
(In case you're wondering why not just use the method I had, it is because I had a text box to enter the PK of that row. I was told that for the web app to be more "user-friendly" the user should not have to enter the PK, but instead click on that row from the gridview and be directed to a page with that row already selected. Then I'll use that method)
i'm getting error on finding control from grid's row.control is an imagebutton which is placed inside a template field.my requirement is if add to cart button is clicked and if that particular book has its volums then it should show message that you need to see its detail and then after selecting its volume you can add it to cart...but i'm trapped in where i'hv to attach bookcod with querystring which is in datakey names of grid.

I have a view that displays all the records of my Roles table. I want to be able to click a Role record and have a list of users that pertain to that role displayed to the right of the Roles list. I'm sure I need to use a view model for this so I can get two sets of models in one view, but I'm not sure how to set up the view model.
Controller code:
[Code]....
Repository (userRep) code:
[Code]....
I can just as easily get the full user list with return db.Users;
So what method needs added to my repository and how should my view model look?

I'm new to ASP.net (and coding in general) and I was very impressed about how easy is to learn enough to create something useful :)
Unfortunately, now I'm stuck on a problem involving gridview sorting and paging: I created a master gridview bound to an sqldatasource, I enabled sorting and paging and then I linked it to a detailsview to enable editing and inserting.
In addition, I set up two other gridviews whose datasources depend on the master gridview.
When a user selects a row and modifies it in the detailsview, the sort takes place and the row is often moved to another page. This can be a little confusing, especially because there are other controls relying on the selected row of the master gridview.
There's a way to find and select the page of the selected row after gridview's databind and sort take place? I tried creating a dataview to search the index of the selected datakey in the databound event of my gridview, but it doesn't work, because it seems that the rows aren't sorted yet. Maybe I should choose another event?

I have a gridview and a details link. Clicking the detail link should take me to a details page with lot of formviews in it. But clicking on the Details link gives me error : 'RadButtonList1' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have a grid view that needs to be shown group wise. The grouping of the data should be dynamic and that is based on the column that is selected.
In general it should list all the rows and based on the coloumn header selected, all the rows should group by that column and should be listed under it. That also needs the template column for the check box and while group by there should be a check all option available for each group.
Even having the collapse and expand option for each groups is required.
I currently use VS 2005 and later will use 2008 and 2010, but will use the aspx code and not xaml.
I've got one columns of check boxes in a GridView, when i select the checkbox entire record(75 columns) is poupulated into formfileds resided just below the gidview. The problem I'm having is that when i selelect 50th record of database(db have 100 recrds) the view state should be on 50th record level but it is scroll over to the toplevel after selecting the checkbox, if user wants to select the 51st record again he scroll to that level.
I would like to display the selected total in the grid view footer. Like if i select 2 check boxes i would like to display the checked total amount in the label provided in the grid view. How can i do this.
