How to get BoundField value during Insert of DetailsView

joker77 — Wed, 18 Apr 2007 09:56:25 GMT

Hi there,

I'm altering the Insert method of a DetailsView control, and would like to know how to get the values being inserted - i.e. what is displayed on screen in the BoundField

I have a NewItem.aspx page, which calls the method public int Insert(Item x) to insert the record. Within here is where I'd like to know the values of the BoundFields but can't seem to see how.

I've tried searching but you can't search just on the Blinq Preview forum which is a bit of a pain.

Thanks

Newbie question here...how do you run it?

Newbis — Fri, 30 Oct 2009 15:57:45 GMT

Kind of a Newbie question here...but how do you run blinq once you install it? I ran the install, it said it completed successfully, but it didn't add anything to my Start Menu program list, nor do I see any new menus inside Visual Studio 2005. I tried to run Blinq command lines from cmd and from Run, but it just said that Blinq was unrecognized. I'm doing a search of c:\ now to see if there are any files with "Blinq" in the name. So far, nothing has turned up.

Row not found or changed

cankersore — Fri, 11 Aug 2006 20:34:06 GMT

I've been playing around with Blinq today and everything was working fine until I decided to add a few more relationships in my database and then rerun blinq. Now when ever I try to update a record in any of the tables I get the ROW NOT FOUND OR CHANGED error. I realize there is a way to turn off the optimistic concurrency check, but I'm just wondering why it's necessary and why it suddenly occured after adding some simple relationships.

Just trying to understand the process a little better. Thanks.

My stack trace is below:

Blinq's place in the world

jtlembke — Thu, 14 Aug 2008 17:12:03 GMT

It would really be cool if someone could write a paper with guidance on how to make usage distinctions between all these great new frameworks Microsoft is developing. Right now my mind is boggled trying to grok ASP.NET MVC, Dynamic Data, Subsonic and umpteen other new gems, all coming from the ASP team! The problem spaces for these new things are so similar, I for one could use a pre-digested comparison analysis.

Thanks,

Jeff

Using blinq with Visual Studio 2008 RTM

rjmiller — Thu, 29 Nov 2007 19:39:38 GMT

Any idea when blinq will support VS 2008 RTM? I tried it today and I get the following error message when I try to run blinq.exe:

Error: May Linq CTP is not installed or configured correctly. You can download it from http://msdn.microsoft.com/data/ref/linq/ If you are running Blinq from a command window, close it and open a new one after installing the Linq Preview.

Or is there a way to work around this?

Getting the Identity of the last Inserted row!

redtap — Fri, 04 Aug 2006 10:16:25 GMT

Can anyone tell me how to get the identity of the last inserted row? I'm using DLINQ so please don't tell me how to do this in SQL as I know this. In SQL I would use SCOPE_IDENTITY() or @@IDENTITY (generally not the latter)

Please help! I have project to be finished ASAP and this is the only bit holding me back!

Thanks !

Multiple foreign keys between two tables

Brad Engels — Mon, 14 Jan 2008 14:51:53 GMT

I have been working on an issue tracking application and have decided to do my database access using linq. The only real problem I have run into is how to link two tables that have multiple foreign key relations.

I have table [Issue] and table [User]. [Issue] has fields issue_creator_id and issue_assigned_id, both related to [User].

The problem that I run into is that when I access Issue.User.user_name with linq, I cannot choose between the creator or assigned relationship.

Other than creating a different User table in the dbml for each time I have multiple foreign keys, what can I do?

Menu text truncation

micjones — Thu, 03 Aug 2006 21:40:14 GMT

Some of my database tables have long, descriptive names like "RateScheduleType". I added spaces in the title attributes of the sitemap file for readability, however, the menu items are truncated. For example, what should read "Rate Schedule Types" reads "Rate Schedule Ty...", and instead of "New Rate Schedule Type", the submenu reads "New Rate Schedul...". I've been messing with the stylesheets to no avail. Any help would be appreciated. Thanks.

Customizing Blinq generated Master Pages

micjones — Wed, 12 Dec 2007 23:35:59 GMT

Is anyone familiar with customizing Blinq-generated Master Pages? I'm trying to use long table names, and the menu control on the master page truncates them. I tried using an example that narrows the menu control, but widening does not work for me. Any help from the Blinq forum would be helpful. Thanks.

Updating a database column of type ntext is NOT working from BLINQ.

vsakunala — Thu, 01 Nov 2007 18:56:24 GMT

Hi All,

I am getting "Value cannot be null. Parameter name:body" error while updating ntext column in the database. The column attributes are

[Column(Storage="_ShortDescription", UpdateCheck=System.Data.DLinq.UpdateCheck.Never, DBType="NText" )]

So, I changed the UpdateCheck to "UpdateCheck=System.Data.DLinq.UpdateCheck.WhenChanged" and got "SQL Server does not handle comparison of NText, Text, Xml, or Image data types ". Got the same error when the setting changed to "UpdateCheck=System.Data.DLinq.UpdateCheck.Always"

Any suggestions please

Thanks

MrJingles — Mon, 08 Oct 2007 10:59:42 GMT

Hi. The DetailsView displays the Data fields wrong. When I click on NewWorkOrder it shows a dropdown list for my workorderID....this is supposed to be a text box and i must enter the ID. This is my primary key in the table. is there a way to fix this?? How can i change the template so that it works? thanks

BLINQ Created DropDownList - Sorting

drewkbell — Mon, 15 Oct 2007 19:58:17 GMT

I've edited a dropdownlist to show a customerName instead of a customerID. The problem I have is that the sorting is still going by the customerID. I've edited the GetAllTblCustomer sorting to use the customerName as a default in the StaticMethods.cs. This works on the GridView generated page. The dropdownlist is still sorting based on the customerID.

I am sure there is something simple I am missing. But, I have tried editing every different property I can think of with no luck.

- Thanks in advance

Hi all,

I'm having an issue with some links that Blinq is creating that refer to associated child records of each row in a GridView. (Like the "View Orders" link on each Customer row) When I click on the child link, I get the following error (see below).

I thought it might be due to something I changed in the application so I regenerated it into a separate directory but it still happens there. Any ideas?

Server Error in '/timtest' Application.

Validators to Retain Details View data

micjones — Wed, 10 Oct 2007 17:14:31 GMT

I have a problem using CompareValidators. I've tried comparing a value in a textbox with a value in a DetailsView control to no avail. I found that they must be in the same container for comparing values. I've tried comparing values in my code-behind, and when the comparison fails, a blank Web page is returned. I really do need to figure how to retain values in a DetailsView when a comparison fails so that the user need not re-enter the entire form. Any help would be appreciated. Thanks.
