C# - Updating SqlDataSource Parameter Via LinkButton?
Apr 10, 2010
I'll try to explain what I'm doing the best I can, but I'm pretty new to asp.net so be patient with me. I have a SqlDataSource which returns a simple select statement based on the WHERE clause using @COURSE_ID
What I want to-do is every time any one of 2 (this will change as it's going to be generated) asp:LinkButtons are pressed, they will change the @COURSEID value which i'd like to associate with the specific button.
Buttons:
<asp:LinkButton ID="LinkButton2" runat="server" onclick="MenuUpdate_Click">Course1</asp:LinkButton>
<asp:LinkButton ID="LinkButton1" runat="server" onclick="MenuUpdate_Click">Course2</asp:LinkButton>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:connString %>" SelectCommand="SELECT Chapter.chapterName, Chapter.chapterID
FROM Chapter
WHERE Chapter.courseID = @COURSE_ID
">
C#
protected void MenuUpdate_Click(object sender, EventArgs e)
{
Parameter p = SqlDataSource1.SelectParameters["COURSE_ID"];
SqlDataSource1.SelectParameters.Remove(p);
SqlDataSource1.SelectParameters.Add("COURSE_ID", THIS NEEDS TO BE VALUE ASSOCIATED TO BUTTON);
ListView1.DataBind();
UpdatePanel1.Update();
}
If anyone has any suggestions that'd be great, I've been trying lots of different things all night with no success :(
I have to use SQLDataSource for inserting, updating and deleting in database through gridview instead of using SqlDataAdapter and SqlCommand object. I have to do it in ADO.NET (means C# code).
So I have a gridview within a gridview (I have a one to many table) my first gridview is working well, but my second gridview has a sqldatasource that has a select parameter(the default value was just for testing)
during my Gridview1 row databound I am trying to grab the columns that match the tripID. But dsCountryByTripID which is my datasource, is only going inputted with the last tripID.

I want to add a GridView control to one of my views that is backed by a SqlDataSource. The SelectCommand query is parametrized on the aspnet_Users.UserId GUID for the currently-logged-in user, so I need a way to pass the user ID as a parameter.
I read How to utilize ASP.NET current user name in SqlParameter without code-behind and decided to create a custom Parameter named UserIdParameter:
namespace MyApp.Web { public class UserIdParameter : Parameter { public UserIdParameter(string name) : base(name) { } protected UserIdParameter(UserIdParameter parameter) : base(parameter) { }
Unfortunately I get a Parser Error ("An error occurred during the parsing of a resource required to service this request. review the following specific parse error details and modify your source file appropriately.") with the following highlighted in red:
<my:UserIdParameter Name="UserId" />
Visual Web Developer 2010 Express is also informing me that "Element 'UserIdParameter' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing."
Do I need to modify Web.config in some way? If not, what do I need to do to be able to use my custom UserIdParameter parameter?
I am using a stored procedure for a sqldatasource to update a formview. I believe that I am passing the Obligation_Status value correctly to the stored procedure but the oblgation status field is always updated AS NULL in the database. Does anyone know what I am doing wrong?
Gridview has many columns and a Delete button as well. Delete button is a control as TemplateField
[code]....
Now associated SQLDataSource's Delete command's stored procedure is expecting two parameters. One is going from DataKeyNames (RowID), other one i wanna pass is the Text of btnDelete (True or False).
i have placed a SqlDataSource component on my aspx page but while configuring the SqlDataSource in the "Test Query" Step I am passing the following parameters :But when i click ok it returns following error:This error occurs when i pass the string :
INFO, WARN, ERROR,
I have tried a lot of combinations but nothing works. It works only if i pass one of the three words in single quotes like this :'ERROR'Infact the INFO WARN and ERROR are the various levels available in the table. Each record can have only one level and in the sql query i am using IN("-----") to match the criteria, hope you understand.
Being new to using the declarative syntax of SqlDataSource I am trying to figure out a way to set the value of a parameter to a stored procedure. I have a Client_ID that is passed via the Request Object and I need to set the Client_ID before the stored procedure of the SqlDataSource is executed.
Does the stored procedure parameter have to be predefined in the ASPX markup or can it be added dynamically in the code-behind? Would anyone have an example that demonstrates the SqlDataSource markup with a stored procedure and parameter as well as setting that parameter value in code-behind?
For SqlDataSource I can configure the external source for the incoming paramater. For example it might be a QueryString, Session, Profile and so on. However I do not have an option to use User as a source.
I know that I could provide value for the parameter in Inserting,Selecting,Updating,Deleting events. But I do not think that this is an ellegant solution because I have some parameteres already definied in aspx file. I do not want to have parameters defined in two separate places. It makes mess.
So can I somehow define this parameter in .aspx file?
<SelectParameters> <asp:QueryStringParameter DefaultValue="-1" Name="ID" QueryStringField="ID" /> //User.Identity.Name goes here as a value for another parameter </SelectParameters>
I am using the stored procedure below for the select command of a SqlDataSource, and I'm trying to pass a query string parameter, but I get this error:
Procedure or function 'ActivationCampaignGetById' expects parameter '@campaignId', which was not supplied.

I have the need to display a date in this format: dd/mm/yyyy. This is actually being stored in an ASP.NET textbox and being used as a control parameter for a select on the GridView. When the query is run, though, the date format should change to 'd M y' (for Oracle). It is not working. Can someone tell me what I'm doing wrong? Right now I am pushing the "new" format to a invisible label and using the label as my control param:
$(document).ready(function() { //datepicker for query, shown traditionally but holding an Oracle-needed format $('[id$=txtBeginDate]').datepicker({ minDate: -7 , altFormat: 'd M y' }); //get alt format var altFormat = $('[id$=txtBeginDate]').datepicker("option", "altFormat"); //set date to be altformat $('[id$=lblActualDate]').datepicker("option", "altFormat", 'd M y'); });
I have an SqlDataSource query that should use an input parameter for multiple integer values, like:
select * from table1 where TableID IN (1,2,3,4,5)
->
select * from table1 where TableID IN (@IDValues)
How do I do that ? Default parameter settings won't work, returning "invalid integer value" . I suppose that parameter should be passed as some kind of array that SQL recognizes as multiple integer values , but what's the correct way of setting this ?
I am using SqlDataSource control that retrieves information based on a city value from another control (textbox) on the page entered by the user.
[Code]....
The query works fine when the user enters a name of a city. However, if I leave the textbox blank and enter nothing, no records are returned by the query.I need all records to be returned when user leave the textbox blank and there is no value of the city.How to do that?is there a default value can do that?
I have a link button inside an update panel. The problem is the link button on postback is updating the whole page. Tried it with a normal button and the page is not refreshed all. Here's the code.
I have a SQLDataSource control that is calling a database stored procedure, and passing quite a large number of paramaters, and the stored proc returns records that populates a gridview control. When I walk through the code behind to determine the values being passed, is there any way that I can see exactly how the parameters are being formated and passed to the stored proc?
I am facing a small issue in using a DropDownList that has only two values (AND and OR) which i want to use to configure a SQL Query in a SqlDataSource. How can i use this thing by passing the value in a SqlDataSource Select Query in such a way to Bind the Result to a GridView. I want something like this -
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen @Option InvoiceNo = @invoiceno where @Namen is from a DropDownList and InvoiceNo is from a TextBox
I m having a problem in specifying this @Option parameter from a DropDownList which contains only two list items - AND and OR. On the Basis of the Selected Value from this DropDownList i want to execute query like
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen AND InvoiceNo = @invoiceno
or
SELECT [somefields] FROM instinvoice WHERE Namen = @Namen OR InvoiceNo = @invoiceno
Using the Query with @Option gives me a Parsing Error. Why is that so. How can I implement this scenario.
I am trying to get the uniqueidentifier value from a insert SP and retreive that using a sqldatasource and pass that value to store files in the relevent folder.
