I have a SqlDataSource(named SQLDS1) which retrieves 4 value from database(ProductName,ProductCost,ProductID). I Have a DropDownList(DDL1) control and its DataSource SQLDS1.
DDL1 Selected data field to display is ProductName
DDL1 Selected data field to value is ProductCost
I did all this in Visual Part without any line of code. But in the code behind , When i select an item from DDL1 i need its ProductName,ProductCost and Also ProductID. It is simple to get first two. But how can i get the ProductID. Is there anyway to get ProductID from SQLDS1.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
Is me again,and now i facing problem to retrieve a single record from the database. here is my code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim user As String user = TextBox1.Text Dim varpassword Dim mydata As SqlDataSource mydata.SelectCommand = "Select * from tbluser where uLogin = '" & user & "'" varpassword = mydata.SelectCommand.uPassword End SubEnd Class
but i get the error : 'uPassword' is not a member of 'String' i wan to retrieve the password of that user,can anyone help me? thanks
hello friends iam newlly joined in to company any one can help me how to bind individual controls to a single SqlDataSource Control.. my problem is "i have different text boxes and dropdown boxes and what i want to do is if i enter primary ker field(employeeno) in the text box automatically i need to get that particular record and i need to populate it to the Respective controls... is there any chance of doing this by using a single datasource control..
First I want to say thanks to the folks how have helped me over the past week or two. I'm missing a crucial piece of insight. How do I read a single piece of data from a SqlDataSource which only hold one row of data into a declared variable? string zUserName = SqlDataSource.(get the value in the row that is labeled UserName) It really doesn't matter to me whether it is an SqlDataSource or some other data container that hold the data I've selected. My goal is to be able to read some data from some predefined datasource into a declared variable. If I am approaching this problem in the wrong way any advice or article links you could give me would be grealy appreciate. Thanks, Bill

hi 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, mcm
Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. 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'm trying to go through a checkbox list and inserting them into a database using a sqldatasource with the following code:For Each li As ListItem In Locations_Checkbox.Items If li.Selected = True Then
Dim DataSource2 As SqlDataSource = CType(InsertProgrammeLocations, SqlDataSource) DataSource2.InsertParameters.Add("ProgrammeID", li.Value) DataSource2.Insert()
End If Next When more than one checkbox is ticked, I'm getting the error 'The variable name '@ProgrammeID' has already been declared'. How do I close or reset my Datasource before I try and use it again? Thanks for your help
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
Hi, 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?
Hey all,I've just started to use asp.net and so far have found it fairly easy. The only problem I've come across is with putting variable clauses into the SqlDataSources.This is one example of what I've done trying to get this to work. <asp:SqlDataSource ID="ClaimsDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" SelectCommand="SELECT TOP 20 dbo_ClaimStatus.ClaimStatus, dbo_CLAIMS.PACKET, dbo_INSURED.NAME, dbo_FEES.INSURER, dbo_FEES.CLAIM_NUMBER, dbo_CLAIMS.LOSS_DATE, dbo_CLAIMS.RECEIVED, dbo_CLAIMS.LOSS_LOCATION, dbo_CLAIM_TYPES.CODE FROM ( ( ( ( dbo_CLAIMS INNER JOIN dbo_CLAIM_TYPES ON dbo_CLAIMS.CLAIM_TYPE = dbo_CLAIM_TYPES.CODE ) INNER JOIN dbo_ClaimStatus ON dbo_CLAIMS.StatusID = dbo_ClaimStatus.ClaimStatusID ) INNER JOIN dbo_FEES ON dbo_CLAIMS.PACKET = dbo_FEES.PACKET ) INNER JOIN dbo_INSURED ON dbo_CLAIMS.PACKET = dbo_INSURED.PACKET ) WHERE dbo_ClaimStatus.ClaimStatus = @claimStatus"> <FilterParameters> <asp:QueryStringParameter Name="claimStatus" QueryStringField="ctl00$MainContent$claimStatus" /> </FilterParameters></asp:SqlDataSource>I'm posting claimStatus from a previous page using PostBackUrl on an <asp:Button /> tag and claimStatus is an <asp:DropDownList /> tag.Any idea's as to why this doesn't work?Nalum

Could someone help me with syntax? Everything works until line 23. At that point, I get a NullReferenceException. When I examine the SqlDataSource object, everything inside reads "Object cannot be null" or "The pointer for this method was null." The SQLDataSource looks ok, just before executing line 23. Does anyone have a complete example of how to do this ADO operation?

Hi, i am trying to use a sqldatasource to update a table and when i go and update the table it puts a null value in for all of my fields.
