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?
View 2 RepliesI have a details view that is bound to a sqldatasource. The datasource has some extra parameters besides the updated data on the screen, they are;

I am want to take the old values of the details view from the detailsview1_itemupdating event and add them as a parameter to my sqldatasource.

So how can I then add this as a parameter to my sqldatasource?
I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.

I haven't used these in awhile. I was just wondering is it possible to pass values or parameters to a user control from the aspx page. Say you register a control and then use it using something like
<uc1:SampleUserControl id="SampleUserControl1" runat="server"></uc1:SampleUserControl>
style syntax. Can you pass parameters in there?

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');
});
after I pass querystring parameter to page,page works as expected,but after that when I change my control parameter(dropdownlist selected value how can I set querystring to null or empty...

- When I execute my query within Enterprise Manager giving the "Country" parameter a value of US, it returns the expected records
- When I assigned that value either programmatically or within the SelectParameters of my SqlDataSource, no rows are returned at all...
I have this as a parameter in the sproc:
@Country char(2) = NULL
and the relevant WHERE clause entry is:
AND (@Country IS NULL OR a.CountryCode = @Country)
My SelectParameter is:

I've tried adding the "DefaultValue" property set to "US" and also tried setting it as sds.SelectParameters[4].DefaultValue="US"
When I do either of these things I get no records returned...

Due to certain reasons, in our ASP.NET web application, it is not recommended to use Response.Redirect("something", True). It should be used with False for the endResponse parameter. We want to enforce this with a custom FxCop rule. I've managed to find the usages of Response.Redirect, but now I want to find the value of the endResponse argument. How can I do this?
We're using the following code:

I've used Introspector and thought the endResponse parameter was an integer behind the scenes, but I'm not so sure anymore. Anyway, there don't seem to be any booleans in the methodCall.Operands.

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)
{
}
protected override Parameter Clone()
{
return new UserIdParameter(this);
}
protected override object Evaluate(HttpContext context, Control control)
{
return Membership.GetUser().ProviderUserKey;
}
}
}
In the ASPX view I then added:
<%@ Register TagPrefix="my" Namespace="MyApp.Web" %>
in a line after the <%@ Page ... %> line as well as:
<SelectParameters>
<my:UserIdParameter Name="UserId" />
</SelectParameters>
within the asp:SqlDataSource element.
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?
