Forms Data Controls :: Deleting A Record On A File With Multiple Keys / Access The Rest Of The Keys?
Feb 8, 2010I have a DataGrid that I need to be able to use to delete records form a file
[Code]....
[Code]....
I use
((TextBox)GridMenuOptions.Rows[e.RowIndex].Cells[1].Controls[0]).Text;
To access the data in the Grid for updating, but it doesn't work for deleting
I can use
string id = GridMenuOptions.DataKeys[e.RowIndex].Value.ToString();
but that only returns the first key.
How do I access the rest of the keys?

Forms Data Controls :: FormView Keys Count Is Always Coming Zero?
Aug 11, 2010I have a very simple formview which opens fine with FirstName and LastName as the values in it. But when I click on the update button and inside the onitemupdating method the Keys count is always coming Zero. I have failed to understand why?
Here is my simple Forview:

Forms Data Controls :: Compare Integer Value To Primary Keys Of A Detailsvew Datasource?
Mar 8, 2010I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.
What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.
How would I go about doing this? Is there some sort of compare method for the datakeynames property?
Configuration :: Web.config AppSettings - Keys Referencing Other Keys?
Dec 7, 2010My current project has many peripheral systems and many different environments (testing, integration, development etc). As expected, we're using .config files to dynamically manage everything.
Instead of updating each relavant key when deploying to an environment, I was hoping there was a way to change 1 key only. Such as:
<add key="Environment" value="Development"/>
<add key="WebServiceLocation" value="http://<<Environment>>/text.asmx"/>
I've done some searching and haven't come up with an elegant solution. I'm aware that .config files can make use of system variables, but this seems like a bit of a high wire act.
Insert Foreign Keys With Dynamic Data?
Mar 21, 2011I am having trouble with foreign keys Dynamic Data and entity framework 4.0. It feels like there is a problem with the entity association but I am not sure. I have multiple fields representing the foreign key on the insert page.
When I try and insert data I get an error A dependent property in a ReferentialConstraint is mapped to a store-generated column.
Column: 'CommentId'
My data is a very basic one to many relationship, the foreign key in question is BookId in the Comment Table.
[code]...
When I let the scaffolding do its thing, I get multiple fields representing the foreign key.
Displaying Values For Foreign Keys In Dynamic Data Web App?
Nov 4, 2010I have the following tables in my database which are as given under:
[code]...
My requirement is instead of getting the PromotionID values displayed for columns CustomerPromotionDiscountID & EmployeePromotionDiscountID, it should display the respective DiscountAmount. Which is not happenning for some reason.
I somehow found a workaround where if i define the datatype for columns CustomerPromotionDiscountID and EmployeePromotionDiscountID as nchar or nvarchar, it displays the DiscountAmount.
Wanted to know if there is any better way of doing this without changing the datatype for my columns?
MVC Class Level Custom Data-annotation And ModelState Keys?
Apr 10, 2010I have custom class level validation attribute, inheriting from ValidationAttribute, on my model.
How come it doesn't register a key in the ModelState when its IsValid is false? I can see the the error message in the ModelState.Values collection, but the ModelState.Keys collection only shows an empty string "". Can I provide a key for it - presumably this is because its not assigned to a property?
I wanna be able to use ModelState.Remove in my controller to remove this error upon a certain condition, but I have no Key!
C# - Retrieving Keys And NewValues Within A Formview With Manual Data Binding
Jul 25, 2010I have a Formview binded in the code file to a generic list. Now, upon editing of a record, I wish to access the Keys and NewValues out of the FormViewUpdateEventArgs parameter of the ItemUpdating event handler method. From what I've tried and searched over the internet as of now, I've come to know that updated values are only available if the Formview is set a data source control on the markup page else they'd be null. Is this true?
Secondly, at this moment I am casting the sender object to formview and individually filling each object property by using FindControl method to find and retrieve values present in the controls. Is this the best way to do this task? As an example, this is what I am doing atm:
FormView currentForm = (FormView)sender;
ListObject.ID = new Guid(((HiddenField)(currentForm.FindControl("hdnID"))).Value);
ListObject.Name = ((TextBox)(currentForm.FindControl("txtName"))).Text;
