DataSource Controls :: Update / Insert And Delete SQL Statements For Define Custom Statements Wizard

Feb 23, 2011

I'm using the 'Configure Data Source' wizard to connect to my database and show the dataset in Gridview. I want to be able to update, insert and delete entries but am unsure how to build the query. I can write simple update statments to change database entries but how can I do this for entries that have been changed within the gridview?

DataSource Controls :: Type Safe SQL Parameters And Update/ Insert Of Database

Feb 1, 2010

I have been in the process of updating my code with security methods, and I've been learning this from [URL] (or "Security Guidelines: ASP.NET 2.0"). In the middle of the page under "When Constructing SQL Queries, Use Type Safe SQL Parameters" it says "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". Now, what they suggested was to use code like:

"DataSet userDataset = new DataSet();
SqlDataAdapter myCommand = new SqlDataAdapter(LoginStoredProcedure", connection);
myCommand.SelectCommand.CommandType = CommandType.StoredProcedure;
myCommand.SelectCommand.Parameters.Add("@au_id", SqlDbType.VarChar, 11);........"

But, I was already using code like:

"var dataSource = (SqlDataSource)form1.FindControl("sqlDataSource5") ;
dataSource.UpdateParameters.Add("someVal", val);"

So now, to use type safe parameters, I decided to include it like:

"var dataSource = (SqlDataSource)form1.FindControl("sqlDataSource5") ;
dataSource.UpdateParameters.Add("@someVal", DbType.Int16, val);
dataSource.UpdateParameters["@someVal"].Size = 1;"

So, that would be how I would modify my current code base to use type safe parameters in sql updating/inserting.

Getting to my actual question, as it was said "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". First off, this suggests that this should apply to unfiltered input. Also, in their example they only did this for an ID.

So, what I'd like to know, when it comes to "unfiltered input", does this mean as long as the input is unfiltered I must use type safe parameters, or even filtered input shall have this (just to be sure), like, input that has been ran through a regularexpression check? Shall I do this for all values I insert/update into the database, or just IDs and important things?

The way I see it right now is that it would be a good precaution to just do type safe checks on everything (literally) that updates/inserts into the database just to be extra safe. But, I really am unsure if this is really the best idea, because if I did, would this possibly cause overprocessing of information? Can this cause too much strain on server resources? If my fears serve true, what would be a good suggestion of how I could implement this properly without having to worry about what I said?

DataSource Controls :: Sql Insert Failing On Detailsview Insert Or Update?

Mar 6, 2010

I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:


However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?

I can supply additional vb code and the aspx code if needed.

This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'

This is the first non-null column.

I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.

C# - How To Create A Generic/parent Type That You Could Send To Methods Without Having To Define An Overload For Each Type

Mar 5, 2011

I'm trying to create a validation layer that will contain methods to validate all my objects (in my Business Objects layer) .. but when I try to reference both the validation and business objects to each other I get a circular dependency error .. so I've decided to create a new layer (BLL) to validate the objects for me and I'll be able to reference both the validation and the object layers.

so I want to build some kind of class/interface -I don't know what fits more- to be like a generic type or a parent type that my method could accept it as a parameter and check for it's Name/ID property. Instead of defining a new method overload for each object type I have

DataSource Controls :: Update Another Table Automatically As Row Entered In First Table?

Mar 1, 2010

I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.

Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:


"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.

"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?

DataSource Controls :: How To Change A Table Column Data Type

Jan 21, 2010

I attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :


So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.

DataSource Controls :: DetailsView Update And Insert Buttons Do Nothing

Jan 14, 2011

Not sure where I went wrong with this one, but I can't figure it out now... I've got a DetailsView in an UpdatePanel. A dropdownlist controls which person's details are displayed in the DetailsView. I have the DataSource set to an ObjectDataSource, which has select, insert and update methods defined. I also have a method for the ItemCommand, ItemInserting, ItemUpdating and DataBound events of the DetailsView specified.

When I click "New" or "Edit" on the DetailsView I get the open form with either the details for the current person, or a blank form, exactly as I would expect. But when I click the "Update" or "Insert" buttons it does absolutely nothing. I have it running in debug, and have put breakpoints in the ItemCommand, ItemInserting and ItemUpdating methods, right at the top, and it never goes there. The form remains open, and nothing happens. If I click "Cancel", it posts back and goes back to ReadOnly mode.

A couple more minor details that may be important: This page is using a Master page, which is where the ScriptManager is. I'm actually using the ScriptManager from the AjaxControlToolkit. I also have a GridView in this same UpdatePanel, and that has a FileUpload control in it. Because the FileUpload control doesn't work properly without some tweaking, I have to call a RegsiterPostbackTrigger method on page load to link it back to the Master page's scriptmanager. Not sure if that's causing any issues...?

I had this working fine, but then as the page got more complex and I had to change some of the code, at some point it just stopped working and now I can't figure out how to get this working again... I'm happy to post code if necessary, just thought I'd try this first to see if anyone has a quick idea for what to check.

DataSource Controls :: Unicode Data By Default - In Every INSERT And UPDATE

Apr 18, 2010

I have a web project with more than 100 input boxes , so in every INSERT and UPDATE to sql server in front of sql statement I must put the golden N word, so it will be in UNICODE mode. Do we have some alternative of this? How can i make it in EVERY UPDATE and INSERT to sql server in data layer level- make it like u insert UNICODE (without N word) How can you get MSSQL server to accept Unicode data by default into a VARCHAR or NVARCHAR column?

I know that you can do it by placing a N in front of the string to be placed in the field but to by quite honest this seems a bit archaic in 2008 and particuarily with using SQL Server 2005. Example:

cmd = New SqlCommand(sql, ConnectionFromEnum(whichDatabase))
i = cmd.ExecuteNonQuery()


the question is : Am I suppose to make something with SQLCOMMAND to set- "enter evthng like it is UNICODE, with N auto"? or i must specify UNICODE by default in somewhere else? just to indicate that i already set in web.config

<globalization requestEncoding="utf-8" responseEncoding="utf-8" fileEncoding="utf-8" responseHeaderEncoding="UTF-8" culture="en-GB"/>

So global questions HOW TO MAKE INSERT AND UPDATE Unicode by default in every insert and update methods, without placing N word in front of literal string?
