Forms Data Controls :: GridView And DetailsView Master To Detail
Apr 7, 2010
I am using a GridView and a DetailsView to establish a master to detail form, the idea is to let user select a record on Gridview and Detailsview will load selected record for editing. Here is declaration for the ODS and Detailsview.
[Code]....
this is working fine when I select a record from GridView and edit/update it in DetailsView. But it's not working so well when I insert a new record using DetailsView, because after insertion the selected record remains as the record selected in GridView.
I am using the multiview which on one view has my gridivew and the other has my detailsview. My gridview is a template gridview and I have a button for edit and another for delete.What I want to do is when either the user clicks the edit or delete buttons that the appropriate record is selected and the multiview view is changed to the detailsview showing the selected record.My datasource is microsoft's object container datasource NOT the objectdatasource and I am using model view and controller design pattern in my coding.
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.
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'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.
I use Gridview along with Formview for master/detail viewing. When I change sorting in gridview selected index changes, too. I mean, eg first top record is still selected but it's another id. What I want is to keep id of selected record, in case of need changing a page
I 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.
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.
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
So here is the situation - there is data on master records - its a hierarhical view - something like (ID, IDParent, Title) and detail data - (ID, IDMaster, Details)
And like to build UI using an TreeView - binded with master data - and an GridView - binded with detail data.
Question is witch property to use to create the master/detail chain between Datasources - oh, I've forgot to tell I'm using an ObjectDataSource?
I have a gridview that displays some records....i have added a new column to it called Edit....now when i click the edit link it should take me to a new page where i can edit that particular record only.....how do i go about it? I am using forms and no inbuilt ASP.NET controls except gridview....so i need to write queries for the same.....plz post code if possible
I am using a Datalist and a Listview in a Master/Detail relationship. Each time a DataList item is bound, a Listview is loaded dynamically. I have provided the relevant Layout and Item templates. It is worked fine for one item. But for more than one item, it will raise the following error: "An item placeholder must be specified on ListView 'ItemListView'. Specify an item placeholder by setting a control's ID property to "MyLayout$itemPlaceholder". The item placeholder control must also specify runat="server". Despite having set up the item placeholder.
I made my own master-detail pages using a listview. Rather than url, I use a listview event to set a session variable and response.redirect to the detail page, which on Page Load, loads the data from the database using the session variable, where it can then be edited. The details page is basically just text boxes and dropdownlists, but I used some third party controls and it all looks really sharp.
Here is the corner I pained myself into. Several dependent dropdowns on the master page filter the main listview. If I go back to the master page using response.redirect, the user would have to use the dropdowns again just to get back to where they were before they went to the details page. This is just not going to work.
To further complicate things, I wanted the master page to have paging on it. So if a back button reloads the page, they would have to set the dropdowns again, and page through the data again if needed. Egads.
The closest I have come to working is using a javascript back back button, but this fails after some postbacks on the details page (that are needed). And of course, the master page isn't refreshed when you go back to it (but I could probably live with that).
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...
I have two tables. One table containing 1 master record and the other table containing multiple records per 1 master record. I want to only display in a gridview (or whatever is best) the master record AND its assocated detail records IF certain fields in the detail records are there. I have been trying to figure out how to do this but I am still a bit of a newbie and I don't how I can do this.
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!
design pattern that works well with Visual Studio data tools against an MS SQL server; to retrieve a subset of an object's fields for all rows, and then on-demand retrieve the remainder for one row. I.E. just the small summary fields that I will serialize to a master grid view, then the larger properties including a large blob that I will render in a detail view. The performance hit from retrieving the large blob with the master result list would be too great.
The data shape is static, and I can define two separate data classes to match the specific summary vs. detail information returned. However that sounds anti-pattern-ish, to define the data classes specifically to suit the presentation layer. It also presents another problem, how to translate from the summary item to the detail item in an object-oriented way?
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
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 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.
