View 1 RepliesI have 2 Linq to Entity queries, here they are:
[Code]....
In "query" there are several columns, 2 of them are NIIN and Qty. In "objViewDDRT" there are only 2 columns, they are NIIN and AvailBalance.
What I need to do is for each row in "query" check to see if the NIIN is in "objViewDDRT", and if it is get the AvailBalance for that NIIN from objViewDDRT.
I have two textbox as naming : txtInitiateDt and txtDisposalDt.
When user give 2nd textbox value from datepicker it should chk whether the given value shouldn't more than to date and also less that 1st textbox value.
I did it & also works good...bt there's an error arise when i host the site on client machine where only framework and database is present.
And the error is "String Value is not in correct dateformat" and fr this exception other events are blocked.
How do I find the time difference between two datetime objects in ASP.NET?

When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?
<asp:Content ID="Content4" ContentPlaceHolderID="leftForm" Runat="Server">
<asp:Label ID="lblStartTimeEnter" runat="server" Text="Start Time:" Width="100px"/>
<asp:TextBox ID="txtStartTime"runat="server" MaxLength="50" Width="250"/>
</asp:content>
<asp:Content ID="Content4" ContentPlaceHolderID="rightForm" Runat="Server">
<asp:label ID="lblEndDateEnter" CssClass="formMargin labelInput" runat="server" Text="End Date:" Width="100px"/>
<asp:TextBox ID="txtEndDate" CssClass="formMargin" runat="server" MaxLength="20" Width="250" ClientIDMode="Static"/>
<asp:CompareValidator ID="cvlDate" runat="server" ControlToValidate="txtEndDate" ControlToCompare="txtStartDate" Operator="GreaterThan" Type="Date" ErrorMessage="Start Date must be before End Date" > *</asp:CompareValidator>
</asp:content>
I am using compare validator to compare date... But Its not working ...I have used calendar extender...with date format as "dd/MM/yyyy"...
View 3 RepliesI got 2 linq results, one of them is as follow.
[Code]....
I need to find out which states in the "query" are not included in the "query2".I can loop through 2 results with nested loop but I think there might be better way of doing the same task with LINQ.Please show me the right direction if it can be done.
have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
I know how to bind a simple objects to a dropdown list. However I am having problems binding my objects which contains sub objects to the control.i.e. with simple object i just do ddl.DataValueField = "myproperty"
with my objects they contains sub objects which i want to bind. I have tried ddl.DataValueField = "sub-object.myproperty" which doesnt work.
firstly a static class only ever exists once and is not an instance. Any static members (ie static int NoOfPeople;) is stored in one place and is shared between all sessions (like the old global variables).
Now static methods is where i'm not 100% sure. If I have a static method that doesn't use any other static members could this cause inconstant results, example (this is a fairly pointless method but just a quick example of the top of my head)
[Code]....
So in this example if two sessions (or threads) were to call this at the same time - would they both get back the expected results, because the method only uses private data (a, b and totalToReturn).Im sure this sounds a little simple but I will be using static methods to build user objects and various other objects that there will have to be a 100% garentee that the objects will not get mixed up between sessions and the wrong things return to the user.
I am trying to check for a condition such that a date in an input control (textbox) is not greater from a date 1 years from current date(exactly) and also it should not be less than a date 1 year back from current date. for eg. if today's date is "21/dec/1990" then usen cannot enter a date in textbox which is less than 21/dec/89 and it should not be greater than 21/dec/1991. for this i first tried to confirm the greater than condition, i wrote the following code:
<asp:TextBox
ID="TxtSessionFrom"
runat="server"></asp:TextBox>
<asp:CompareValidator
ID="CompareValidator1"
runat="server"
ControlToValidate="TxtSessionFrom"
ErrorMessage="CompareValidator"
Operator="GreaterThanEqual"
Type="Date"></asp:CompareValidator>
CompareValidator1.ValueToCompare=(DateTime.Now.AddYears(1).ToString());
but this gave an error: The value '' of the ValueToCompare property of 'CompareValidator1' cannot be converted to type 'Date'.
I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?
View 1 RepliesLets say I am doing a shoping cart. I authenticate the user with a session variable.For example:
If(Request.IsAuthenticated)
// Here I want to add to the shoping cart.
// Can I do the following
Session["Cart"] = "Washing Machine";
Now will this Session["Cart"] value which is washing machine here be unique to diff customers?
In my opinion, these architectures have some differences, such as:
1. 3-layer is a linear architecture, but MVC is a triangle architecture.
2. Presentation Layer of 3-layer includes View and Controller of MVC? And Model of MVC includes Business Layer and Data Access Layer of 3-layer
I think 2 differences above are not obvious or are incorrect!

In specific, what confuses me is that validateRequest can only be possible by a postback as this is how form values etc will be picked up?
