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 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="..."

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?
Hey 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
Hi Folks,
How can i pass a string variable from code behind page to html page on event fire. i want to pass sql qerry to SelectCommand (SELECT * FROM [Tickets] WHERE ([TicketNo] = @TicketNo)) in some variable from codebehind on some event fire.
<asp:SqlDataSource ID="sqldsTickets" runat="server" ConnectionString="<%$ ConnectionStrings:IMTicketingConnectionString %>" SelectCommand="" >
<SelectParameters>
<asp:SessionParameter Name="TicketNo" SessionField="test" Type="Int64" />
</SelectParameters>
</asp:SqlDataSource>
Thanks in advance
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.

Hi All,
I have a question about the datasource that we create on the Report Manager. What is it used for? In the below connection string which is given in the "Connection String" text box of a datasource link:
"Data Source=ProdServer;Initial Catalog=Northwind"
What is this datasource used for? Is it used only to use the ReportServer database or even our queries incorporated in the RDL files will be run against this datasource? I think the latter should not happen because while creating RDL files also, we provide a connection string to run the stored procedures against that datasource.
Please let me know about the same.
Thanks a lot and let me know if the question is not clear.

What about LinQ?

I am using a SQLDatasource to populate a dataview as illustrated below. I run into a problem when I search for a "LastName" that includes an (') Apostrophe ( e.g. O'Reilly) . Searchin for the whole name there is no problem, but when I search for simply O, or O' I get errors.
I am not sure ...when to address names with an apostrophe...
1) On insertion to the database (using a "Replace(LastName, "'", "''") 2) or after they have been entered and they are to be searched for.
If scenario 1, can anyone provide the best way to do this...If scenario 2, how would that be worked into the SQL Datasource code below....

Dim Zip, City As String
Zip = txtZip.Text
City = txtCity.Text
grdZipCodes.DataSourceID = "ZipSearch"
ZipSearch.SelectParameters("ZipCode").DefaultValue = Zip
ZipSearch.SelectParameters("City").DefaultValue = City
grdZipCodes.DataBind()
End Sub
This is supposed to populate a gridview with filtered data. Instead I get nothing, even though in query analyzer if I dont provide a city or a state all results are returned. Is there a reason my gridview is not populating.
this is what my SQL Datasource is :
<asp:SqlDataSource ID="ZipSearch" runat="server" ConnectionString="<%$ ConnectionStrings:something%>" SelectCommand="ZipCodesSearch_s" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter Name="ZipCode" Type="string" Direction=input />
<asp:Parameter Name="City" Type="string" Direction=input />
</SelectParameters>
</asp:SqlDataSource>
In the following example...
EXEC sp_addlinkedserver
@server = 'Shipping',
@provider = 'Microsoft.Jet.OLEDB.4.0',
@srvproduct = 'OLE DB Provider for Jet',
@datasrc = 'C:ShippingShipping BackEnd.mdb'
...can I specify the UNC path of the Access DB instead?
Hi,
New to databases so need some help. While trying to set up data source in control panel, I find that there are no drivers for *mdf files. Just *.dbo and *.xls and others. Can someone tell me what to do. I can't get analysis services to let me access my database, which are *mdf files a friend sent me.
What do I need to do...Can someone help me.

Hi All,
I am using SSRS 2005 (Report Designer), and in 1 of the Report, I have a Report Parameter for example say IMask (Dropdown List), which I am populating by values from the following XML file (Imask.xml)
<?xml version="1.0" standalone="yes"?>
<REPORTCONFIG>
<INVALIDMASK>
<INDEX>0</INDEX>
<IMASK>00000000</IMASK>
<DESC>Custom Created</DESC>
</INVALIDMASK>
<INVALIDMASK>
<INDEX>1</INDEX>
<IMASK>FFFFFFFF</IMASK>
<DESC>Custom Created1</DESC>
</INVALIDMASK>
</REPORTCONFIG>
I have created a XML DataSet whose DataSource is of €śType : XML€śand get the values from the above mentioned XML file by using following XML query :
REPORTCONFIG {}/ INVALIDMASK
The Result of the above XML query is:
INDEX | IMASK | DESC
--------------------------------------------------------------
0 00000000 Custom Created
1 FFFFFFFF Custom Created1
Now, the report Parameter (IMask) which is a DDL has
€śvalue field€?= IMASK and €ślabel field€?= DESC
So far so good, but what I really want :
1) in case of label field is something like this:
€ślabel field€?= IMASK : DESC (for eg; 00000000 : Custom Created 1)
2) If no nodes(<INVALIDMASK>) are present in the XML file, I get no results when the above XML query is fired. So, Is there any way of getting the count of rows returned by XML query.
And in case of no rows I want my Report Parameter (IMask) to have
€śvalue field€?= NONE and €ślabel field€?= NONE
