How To Access SqlDataSource Fields From Code?
Aug 18, 2007
I have <asp:SqlDataSource> in aspx page that is being used by an updateable GridView. However, there are a couple fields in the dataset that contain filenames that I want to access directly in code and place them into some image tags on the page.
This line should give me access to the dataset but how to I access the fields?
Dim myDataSource As DataView = DirectCast(SqlDataSourceGridView.[Select](DataSourceSelectArguments.Empty), DataView)
When the SqlDataSource is a DataReader I would access it with the code below but since this SqlDataSource is a DataSet I can't access it with this code.
If myDataSource.Read Then
If Convert.IsDBNull(myDataSource("CusAgentPhoto")) Then
ImageAgent.ImageUrl = "/photos/nophoto.gif"
Else
ImageAgent.ImageUrl = AgentImagePath & myDataSource("CusAgentPhoto").ToString
End If
If Convert.IsDBNull(myDataSource("CusCompanyLogo")) Then
ImageCompany.ImageUrl = "/photos/nophoto.gif"
Else
ImageCompany.ImageUrl = OfficeImagePath & myDataSource("CusCompanyLogo").ToString
End If
End If
What would be the correct way to get at the DataSet fields that contain the filenames?

How do I access sqldatasource data values in code behind and bind them to strings or texboxes etc. as oposed to using Eval in the markup?
I can create a new database connection, but I would like to use the data values from the autogenerated sqldatasource control
Many thanks,

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.

(The sqldatasource select everything in my "CityTable")
Hope you understand what I mean...

Can you access a SQLDatasource in the code-behind?
Example: label1.text = sqldatasource.field
I am just migrating apps to ASP.NET 2.0...
Confused as to the best approach for paramaterized data access and binding to labels.

Hi,
I have a problem with the <asp:SqlDataSource. The thing that I try to do is to create a SQL statement. I am not sure if this can be done or not ( just started asp.net).
Something like this:
<%
Dim Test1 As String
Dim Test2 As String
Dim Test3 As String
Dim Test4 As String
Test1 = Request("xmbr")
Test2 = Request("xSEL")
Test3 = Request("xpro")
Test4 = "SELECT [jedan], [dva], [tri], [cetiri], [pet] FROM [pet1] where " & (Test1) & " " & (Test2) & "'" & (Test3) & "'"
%>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FinGateConnectionString %>" SelectCommand="<%= Test4%>">
The problem is that is giving me an error that I can’t figure out.
-------------------------------------------------
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '<'.Source Error:

Hi,
I have the following Sql Data Source that I wish to bring back on my page:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FrogConnectionString %>"
SelectCommand="ProposalsCheckNewCustomerData" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:FormParameter FormField="MaritalStatusID" Name="MartialStatusID" Type="Int32" />
<asp:FormParameter FormField="LivingStatusID" Name="LivingStatusID" Type="Int32" />
<asp:FormParameter FormField="DealerID" Name="DealerID" Type="Int32" />
<asp:FormParameter FormField="VehicleTypeID" Name="VehicleTypeID" Type="Int32" />
<asp:FormParameter FormField="FinanceTypeID" Name="FinanceTypeID" Type="Int32" />
<asp:FormParameter FormField="MediaSourceID" Name="MediaSourceID" Type="Int32" />
<asp:FormParameter FormField="DealerContactID" Name="DealerContactID" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
The recordset brings back 7 values that I wish to populate into 7 Labels.
1. Should the SqlDataSource be on the page (between the Head tags) or within the Page_Load command of the Page Behind ?- If its on the page behind do any of you have any sample code to show me how to get the recordset up and running ?
2. How would I bind the results to a label ?- Within my old asp pages it was simple (I'm not saying its not simple here, I am still getting my head around vb.net)- eg <%=rsX("MaritalStatus")%> I guess its something very similar
Thanks for any pointersFizzystutter

My code behind file builds a select statement and I would like to fill an SqlDataSource control with it. Can some show me an example of how I might do that? Maybe something like this?
Me.SqlDataSourceSearchResult.ConnectionString = "ConnectStr"
Me.SqlDataSourceSearchResult.SelectCommand = "SelectStatement"
gvSearchResult.DataSource = Me.SqlDataSourceSearchResult
gvSearchResult.DataBind()

Hi All
It´s my DropDownList data source from my page1.aspx:
<asp:DropDownList ID="ddlChampionships" runat="server" DataSourceID="sdsSearchChampionships" DataTextField="name" DataValueField="id_championship"> </asp:DropDownList><asp:SqlDataSource ID="sdsSearchChampionships" runat="server" ConnectionString="<%$ ConnectionStrings:LocalSqlServer %>"
ProviderName="System.Data.SqlClient" SelectCommand="SELECT * FROM [Tupi_Campeonatos]"></asp:SqlDataSource>
When I put a new championship name in a TextBox and click on the button "ADD", this button event click is called:
Protected Sub btAddChampionship_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btAddChampionship.Click
insertNewChampionshipIntoDataBase()
End Sub
The Page then reloads but my DropDownList is not updated. The way I found to do it is to put the DDList update code after the calling of the insertNewChampionshipIntoDataBase() method, but how???
thnx

I have a sqldatasource in the markup. This is in turn connected to a Gridview. I use Eval to retrieve the database information in the markup but I also need the Eval information in code behind. How can I do this?
I got this far but how (if it's possible this way) can I retrive it?
Protected Sub Test(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If (e.Row.RowType = DataControlRowType.DataRow) Then
this is where i want to get the "MyData" value from the database.
End If

Hi all
I have a GridView on an aspx page, that is enabled for editing, deletion and sorting.
In the Page_Load event of the aspx page, i add a SqlDataSource to the page, and bind the source to the GridView.
When i click the update, or delete button, it makes a PostBack, but nothing is affected. I'm sure this has got something to do with the parameters.
First, i tried having the GridView.AutoGenerateColumns set to True. I have also tried adding the columns manually, but no affect here either.
The code for setting the commands, and adding the SqlDataSource to the page are as follows:
string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName; string selectCommand = "SELECT * FROM rammekategori"; SqlDataSource ds = new SqlDataSource(strProvider, strConn, selectCommand); ds.ID = "RammeKategoriDS"; ds.UpdateCommand = "UPDATE rammekategori SET Kategoribeskrivelse = @Kategoribeskrivelse WHERE (Kategorinavn = @Kategorinavn)"; ds.DeleteCommand = "DELETE FROM rammekategori WHERE (Kategorinavn = @Kategorinavn)"; Parameter Kategorinavn = new Parameter("Kategorinavn", TypeCode.String); Parameter Kategoribeskrivelse = new Parameter("Kategoribeskrivelse", TypeCode.String); ds.UpdateParameters.Add(Kategorinavn); ds.UpdateParameters.Add(Kategoribeskrivelse); ds.DeleteParameters.Add(Kategorinavn);
Page.Controls.Add(ds);
SqlDataSource m_SqlDataSource = Page.FindControl("RammeKategoriDS") as SqlDataSource;
if (m_SqlDataSource != null) { this.gvRammeKategorier.DataSourceID = m_SqlDataSource.ID; }
As mentioned - no affect at all!
Thanks in advance - MartinHN

Hi, Im trying to pull data from 2 fields in the same table into a SqlDataSource that feeds into a GridView, and display them as 1 field in GridView? I have a database table that has entries of users and their friends. so
this tblFriendUser has a column called UserName and another column
called FriendUserName.
I am trying to get a list of friends for that particular user. Note
that if User1 initiated the friend request, he will be listed as
UserName and his friend as FriendUserName, but if his friend initiated
the friend request, it will be vice versa: him being the FriendUserName
and his friend the UserName. So I want the following 2 queries run and merged into
one query in order to return 2 columns only: UserFriendID & UserName, is that
possible? Is my design bad? Any suggestions/advice would help! Thanks a lot!
SELECT UserFriendID, UserName
FROM tblUserFriends
WHERE (UserName = @UserName);
SELECT UserFriendID, FriendUserName AS UserName
FROM tblUserFriends
WHERE (FriendUserName= @UserName);

There are so many ways to use database in asp.net/ado.net, I'm a bit confused about their difference from the performance point of view.So apparently SqlDataSource in DataReader mode is faster than DataSet mode, at a cost of losing some bolt-on builtin functions.What about SqlDataSource in DataReader mode vs manual binding in code? Say creating a SqlDataSource ds1 and set "DataSourceID" in Gridview, vs manually creating the SqlConnection, SqlCommand, SqlDataReader objects and mannually bind the myReader object to the gridview with the Bind() method.Also Gridview is a very convenient control for many basic tasks. But for more complex scenarios it requires lots of customization and modification. Now if I do not use gridview at all and build the entire thing from scratch with basic web controls such as table and label controls, and mannually read and display everything from a DataReader object, how's the performance would be like compared to the Gridview-databind route?

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.

Hello,
Is it possible to access both my database and the ASPNETDB within the same SQLDATASOURCE using SQL Express ?
I want to pull out some user details from the aspnet_* tables within the ASPNETDB
In my database I have created the 'UserId' fields so the relevant joins can take place.
In my web.config:
<connectionStrings>
<add name="mydb" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|mydb.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
</connectionStrings>
In my asp (showing only mydb):
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:mydb %>"
SelectCommand="SELECT [CreateDtTime], [UserId], [Comment] FROM [Log_Dtl] WHERE ([LogId] = @LogId)">
<SelectParameters>
<asp:QueryStringParameter Name="LogId" QueryStringField="LogId" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
Any help would be appreciated.
Thank you
Lee

dsShippingRegion.Select(DataSourceSelectArguments.Empty)Dim myReader As Data.IDataReader = CType(dsShippingRegion.Select(DataSourceSelectArguments.Empty), Data.IDataReader)If myReader.Read Then If Convert.IsDBNull(myReader("ShippingRegion")) Then Beep() Else Beep() End IfEnd If
System.InvalidCastException was unhandled by user code Message="Unable to cast object of type 'System.Data.DataView' to type 'System.Data.IDataReader'."

Hello all,I have what I think should be a simple problem to solve but I just don't quite understand what to do (.NET Framework Developer Center confused me :( ).My code should load the highest SiteID, known as Last_ID into the siteIdBox when the form is in insert mode. My difficulty is in understanding how to use the sqlDataSource correctly. Dim dsLastId As New SqlDataSource() Dim siteIdBox As TextBox Dim dsmLastId As SqlDataSourceMode If FV_Site.CurrentMode = FormViewMode.Insert Then Try
dsLastId.ConnectionString = ConfigurationManager.ConnectionStrings("AquaConnectionString1").ToString dsLastId.SelectCommandType = SqlDataSourceCommandType.Text dsLastId.SelectCommand = "SELECT MAX(Site_ID) AS Last_ID FROM Tbl_Site"
dsmLastId = SqlDataSourceMode.DataReader
siteIdBox.Text = dsmLastId.?????
Finally
dsLastId = Nothing End Try End If If anyone could tell me the code for getting the value from the select statement into the textbox, I would be most grateful.Thank you, m00sie.

Hi all...I've set the DataSourceMode = SqlDataSourceMode.DataSet, and did a .Type return and found that it is actually returning a DataView. A component I am trying to avoid rewriting....requires a dataset that loops through the table, does some cool formatting to a datagrid and then rebinds.Here's the code that I'm trying to send the dataset to....maybe there's just a couple of changes that could make it work with a DataView? int i = 0; string prevsub = ""; while (i <= ds.Tables[0].Rows.Count - 1) { DataRow dr = ds.Tables[0].Rows[i]; string sub = dr["SubHeading"].ToString(); if (sub != prevsub) { prevsub = sub; DataRow newrow = ds.Tables[0].NewRow(); newrow["Title"] = "SubHeading"; newrow[columnName] = dr[columnName]; ds.Tables[0].Rows.InsertAt(newrow, i); i++; } i++; }
