I am trying to use the SQLDataSource from the codebehind. However, I have a problem accessting the ConnectionString.
I declare my connection string in my web.config file, and I declare this as:
Dim DBConn As New SqlConnection(ConfigurationManager.ConnectionStrings("DbConnString").ConnectionString)
My problem arises though when I get to the SQLDataSource. How can I reference DBConn via the SQLDataSource.ConnectionString?

View 4 Replies View RelatedHi,
I have a SQLDataSource, button, textbox, and label. I take the text from the textbox, count it's occurance in the database, then assign the number to the label. The code works but I would like to provide a button that will execute/invoke the SQLDataSource.
I have this in the click event for the button:
Me.label1.Text = SqlDataSource1.Select(DataSourceSelectArguments.Empty)
How do I execute a SQLDataSource from the code-behind for the button click event?
Thanks.
Hello...Can someone help me?I´m getting info of a product via sqldatasource in this way:<asp:SqlDataSource ID="myData" runat="server" ConnectionString="..." SelectCommand="spGetProduct" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:QueryStringParameter Name="Id" QueryStringField="Id" Type="String" /> </SelectParameters></asp:SqlDataSource>In my ASPX page I get the data in this way:<asp:Repeater ID="repProduct" runat="server" DataSourceID="myData"> <ItemTemplate> <p><%# Eval ( "ProductName") %></p> </ItemTemplate></asp:Repeater> My problem is in my code behind because I need some data from this DataSource.For example, I want the Product Name as the page title. So the question is how I get something like this in my code behind:protected void Page_Load ( object sender, EventArgs e ){ this.Page.Title = Eval ( "ProductName") ;}Thanks!
View 2 Replies View RelatedHi, I don't know if i's a silly question.
Now I want to get data from sqldatasource by only write some code,I don't know without creat some data control components if it can be true?
If it can do,how can I write the codes?
Especially I don't know how to write the code witch can "read" data.
(New to ASP.net 2.0 and database connection)
I have created an sqldatasource on the aspx page, which works fine, but how do I get the results from it in the codebehind?
This is probably an easy one.
What is best way to determine if a SqlDataSource is empty (i.e. the query produced no results) in the CodeBehind?
I'm using this:
if (SqlDataSource1.SelectCommand.Contains(String.Empty))
{
//Add code for scenario here.
}
It seems to work, but something just doesn't feel right about it for some reason.
Thanks
I have a database with columnsuserOwnListsuserID uniqueidentifieruserName nvarchar100userList nvrachar100createdDateI
have created successfully a gridview controller to edit these values in
database. The Gridview data is populated by SqlDataSource.I
have also created a EmptyDataTemplate and created a form into it.
There is only one textBox and submit button to create the First entry
to userOwnLists -table.Now I collect the value from EmptyDataTemplate textbox with id userList1 and create a codebehind logic for the submitbutton.protected void Button2_Click(object sender, EventArgs e) { TextBox listName = (TextBox)this.FindControl("listName1", GridView1.Controls);SqlDataSource1.InsertParameters["userId"].DefaultValue = Membership.GetUser().ProviderUserKey; SqlDataSource1.InsertParameters["userName"].DefaultValue = Membership.GetUser().UserName.ToString(); SqlDataSource1.InsertParameters["listName"].DefaultValue = listName.Text; SqlDataSource1.InsertParameters["createdDate"].DefaultValue = DateTime.Now.ToString(); SqlDataSource1.Insert(); }The problem is now that I get error: Exception Details: System.Data.SqlClient.SqlException:
Implicit conversion from data type sql_variant to uniqueidentifier is
not allowed. Use the CONVERT function to run this query.OK. So I Googled a bit and found this:http://scottonwriting.net/sowblog/posts/4690.aspxMy Question is: How do I convert userId so I can insert it to database successfully?This does not work:String userId = Membership.GetUser().ProviderUserKey.ToString(); SqlDataSource1.InsertParameters["userId"].DefaultValue = Convert.ToString(userId);
Hi, I am a newbie in using ASP.NET 2.0 and ADO.NET. I wrote a hangman game and want to record statistics at the end of each game. I will create and update records in the database for each authenticated user as well as a record for the Anonymous, unauthenticated user. After a win or loss has occurred, I want to programmatically use the SQLDataSource control to increment the statistics counters for the appropriate record in the database (note I don't want to show anything or get user input for this function).
I need a VB.NET codebehind example that will show me how I should set up the parameters and update the appropriate record in the database. Below is my code. What happens now is that the program chugs along happily (no errors), but the database record does not actually get updated. I have done many searches on this forum and on the general Internet for programmatic examples of an update sequence of code. If there is a tutorial for this online or a book, I'm happy to check it out.
Any help will be greatly appreciated.

Lets say I have a Sqldatasource that uses the following SelectCommand="SELECT category,name FROM table". How do I get the value on category from my datasource in code behind if I know that my selectcommand always will return one row? Can I write something like datasource.items["category"].Value? Thanks for your help!
View 1 Replies View RelatedHey All,
I'm very new to ASP.NET and have recently begun using the databinding functionality. So far, all I've had to do is drag and drop the various controls and then use the data source wizard to set up an appropriate query. However, now I've got a bit of a different need. In the VB codebehind, i need to be able to ask whether something is true in the database, and then if it is, carry out functions. So, for example, what I need to do is:
if (SQLStatement "Select charttype FROM charts WHERE datasource = " & dropdownlist1.selecteditem.tostring()) Then
'do whatever
end if
Trouble is, I don't know how I would go about binding the data so that I could access it in this way. Any guidance would be very much appreciated.
Thanks,J Rankin

View 2 Replies View Relatedhi all,
in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>.
I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
thanks in advance,

I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource?
I appreciate if you can explain to me the difference and when to use an sqlDataSource
thx

View 5 Replies View RelatedHi,
I have an application w/ n-tier design so I've never used the SqlDataSource up to this point but having to do my own sorting for GridViews is not something I want to keep dealing with. I'd like to take advantage of some of the packaged features too.
My question is: are there any purists out there who opted to use SqlDataSource. If so, what do you think about it? It's nice that SqlDataSource makes things simple but having data classes and dealing w/ exceptions in those classes certainly make an application pretty robust. Should I entertain the idea of using SqlDataSource or stay as a purist and keep doing things the old fashioned way?
