Jan 3, 2011
I Need To Write a Function That I Can Convert SqlDbType To Types That Used In Linqtosql Class . But I Dont Want To Use Switch/Case Or If To Make This Function , I Know That VS.Net Can Make This Types With Reflection Or Other Functions And Propertys .

I Can Make As Same With Switch/Case Or If By Check Dbtype And Other Propertys Of Column But I Need Do With Casting And Convert .

The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.
Is there any difference between accessing a property that has a backing field
private int _id; public int Id { get { return _id; } set { _id = value; } }
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:

I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.
<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox> <a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">
However, I keep getting this error:
Property access must assign to the property or use its value.
When I open an ASP.NET 3.5 project using VWD2010, I get a prompt error message,"The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place."however, my project works successfully.
i get a list of objects from the Entity Framework data context.
var list = context.EntityA;
the EntityA is the main object (contains the primary key), but has a navigation property called "EntityALanguages", which contains language specific properties.
now i want to bind the list to a dropdownlist and need so set DataValueField and DataTextField properties from the dropdownlist.
how can i set the DataTextField to a property of a navigation property, something like:
I have a type that is derived from an Entity generated by the Entity Framework 3. How do I assign one Customer's Order property to the Derived Customer's Order property?
derivedCustomer.Orders = customer.Orders
I'm not actually trying to swap orders; this is just an example of what I am trying to achieve. Has anyone done tried this and succeed?
Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.
my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.
'Person' is not a member of type 'Transient.rowtype[(Id,Edm.Int32(Nullable=True,DefaultValue=))]' in the currently loaded schemas.

I am working on a tool to construct a diagram in asp.net .The user is allowed to select the images from panel [generated dynamically based on user input in dropdown box] and its copy should be created on the diagram area, it should be draggable and should over lay with each other . So far I am able to create the diagram objects dynamically and on click on each object its copy will be created on the diagram area [I am passing the instance from user control to main page] . I have used Drag Drop Extender to apply Drag behavior. Now my problem is which I create more objects the position of already created objects is not retained in the page. I have js code to retain the position for static controls, but don’t know how to apply for dynamic controls.
[Code]....
Am I complicating the whole process ,is there any easy way? .
