I have a Page with a FileUpload control on the top with the "Insert" button, in order to insert pictures Below that, i have a Listview showing all the pics. THis is the way i am placing my Update Panel:
[Code]....
How can i, press the INSERT button and reloads only the Content Template after INSERTING?
I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.
I 'm writing a gridview. When you click a image button in the gridview, it will popup a panel to show detail. But it is not working at the moment.

I'm trying to setup is a News module with article listing paging and article detail paging. I have a GridView with paging that lists my articles just fine. In that list, some article titles have links that direct to an article detail page by passing in the articleID to the details page. I was able to setup my details page, which uses a DetailsView control, to use paging by using an ObjectDataSource with pageIndex and pageSize parameters from the querystring. Once on my detail page, I can use my navigation arrows to move through Next and Previous articles just fine.
No matter which article I click in my article list, my detail page always starts with pageIndex 0 and thus not the article I clicked on. I understand why that is because it's going by pageIndex value instead of articleID. What I need it to do is, set the detail to whatever articleID i pass in, then allow me to navigate Next and Previous to THAT particular article instead of starting me off from pageIndex 0.
[Code]....
article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object
[Code]....
The form collection comes back with the expected prefixes:
[Code]....
And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)
[Code]....
I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.
[Code]....
I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!
I've been experimenting with using EF (asp.net 3.5 sp1) with a master detail page. Using northwind as the database, I'm simply trying to have categories as master and products as detail. I have read everything I could find on the net about the where condition and it still fails with this error as soon as I click the select link in the master grid:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: A property with name 'CategoryID' does not exist in metadata for entity type 'WebAppEF01.Products'.
What strikes me is that the CategoryID column is not exposed by the EF model. That's been rolled up into the navigation element 'Categories' I suppose...but on the surface this seems to create the problem I've running in to. I've tried turning off the autogeneratewhere clause but didn't have success. The code for this page follows below.

My Master/Detail view is working fine, but if i try to add Modal PopUp extender it does not work at all.
[Code]....
adding Modal Popup to this code. I have studied [URL] article many times but could not find problem with my code. My code should display Modal PopUp 2 times. Once New Client btn is clicked & other time when edit inside GridView is clicked.
I have a single web page with master detail form/input layout. Currently the form works in a way like
User opens the page containing both master/detail data entry controls and enters the master information (The details save button is disabled)When he saves the master information, the save master button gets disabled and save details is enabled User continues to enter multiple details which get populated in a gridview at the bottom of page All works well Problem is that, the master part contains a lot of data entry controls (drop down lists gridviews etc)
How do I facilitate the user much more then the current layout? Should he be redirected to a new page after he enters the master record ? How can I improve on this?
I have the basic Master / Detail Views working great with the default ASP.NET MVC Route; however I would like to build some URLs like this: /Class/Details/5 -- General Detail view [Working] What I'm not sure about (and I'm not tied to this URL format, just something roughly equalivent.)
/Class/5/Details/Logs -- Detail View with Logs
/Class/5/Details/Status -- Detail View with current Status
Another way to put this, is like this: /{controller}/{id}/{controllerSpecificMaster}/{action}/ What I'm trying to avoid, is cluttering up my ViewsClass directory with a bunch of Views, which are all basically derivatives of the Details view. I'm on ASP.NET MVC 1 and .NET 3.5 SP1.
i have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.
Im making a Master details web page ASP.NET. I have one aspx page with all the items in a listview, then a link to another page to show the details view, but I dont want to use a asp:detailsview control becasue it generates a table, and I want a more complex layout. I want work each property of the item, but I dont know how. I want to do in LINQ. This is my very bad aprox: I need an orientation of how to get ONLY one item from the LinqDataSource on the page load and not to query the database everytime I need a column. I dont need biding because I only need to show data, not insert, not update, not delete...
View 2 RepliesI am at a stand still here. I have a GridView in which I'm moving the DetailsView (bound to a sqldatasource) to the ModalPopupExtender for Updating. DetailsView for the selected row is contained in an updatepanel with the UpdateMode set to Conditional. My Select function works properly, filling in the fields of DetailsView, but I cannot figure out how to get the Update function to work properly. I think what I am missing is a method to get the the key values and control values into the SqlDataSource UpdateParameters.

This is my main page in which I have collapsible panel and my phone gridview is contained in it. The Initial page loads up properly and shows the gridview. All the errors happen when I select a gridview row for modal popup edit. I get the following errors one after other after ignoring each one of them. I have been struggling with his for almost a week. Following are the sections of the main page and the code in the gridview ascx control. Main GridView User Control Page.

I have an updatepanel in masterpage and information on a repeater within the panel. I want to update this information from the content page, when a user clicks a button in the content page.

I tried this but since button control is in the content page compiler can't find the control.
I am curious as to what people would thing is the best way to implement this. On my overview page, I have a data grid which is sortable and has custom filtering written for it. When you click on an item in the grid, it loads a separate page with details. I would like to implement result paging through on the detail page keeping in the same order as the previous page data grid. Now I've thought of a few ways to do this:
Change the link to be a postback and handle the sort order programatically Sort filter and sort settings on application of the settings in the session Pass the filter and sort settings on the query string to the detail page. None of these seem very clean to me, and option 3 is the only cogent option I've thought of. Am I missing something? Is there a more elegant way to do this?

Details View is not displaying all the data.
Master Detail (in the same view)
View 3 RepliesI have an accordion AJax Toolkit control which at header level displays a list of categories from datatable1 (a distinct list of categories) , and in the content section I want to display the details (possibly in a grid) from datatable2 (a list of all products and detail including category).
There are plenty of tutorials on how to achieve this. However the tricky part is that I don't want to re-query the database on opening each header. I would rather the data is pre-filled for each detail section based on the category and just gets displayed.
I am currently designing a master detail gridview. I have two separate objects defined for them. The parent gridview is binded to the first object and in row databind event I bind the second gridview with the detail object using parent ID.A lot of examples I see on the internet initialize the details object inside the parent class,
public class Author
{
private string name;[code]...
What is the purpose of initializing child class inside the parent class? Currently, I just bind the parent to a separate object & child to a separate object manually in my presentation layer & never initialize child objects inside parent class. Is that the wrong way for OOP ? What is the recommended way to achieve this task for my gridview?
I am trying to build a master detail functionality. It present, there is a web page i.e. page1.aspx with search functionality. When the criteria is entered then the search button can be clicked and then the GridView gets populated with data. In this GridView, a number of the fields of the selected row can be edited as per business requirement. Now I would like the user to be able to see and edit more fields related to the selected row in the gridview. These are extra fields which are not viewable in the gridview. Question: Is it best to have another page i.e. page2.aspx to see and edit these extra fields or is it better to have these extra fields (One in each control) just below the gridview in page1.aspx?

1 3 7
i am creating a model for this structure
Puclis class Model{
public OrderID, Date, Employe;
List<OrderDetail> list ; // this is another class OrderDetails...
}
while saving this model to database orderID,Data,Employe... items are saving Orders table in database. and List<OrderDetail> is saving with for loop to ORderDetail table.
but editing the order and details model is difficult.
I was looking tutorial for Master/Detail and I have one question. If I populate DropDowList with some data from database and run application, DropDownList show the first record from database. And if I choose some Item from DropDownList DataList show result of filtering. How when I run application to populate DataList as Detail using parametar of first Item in DropDownList populated from database?
