Have you tried to change the width and height to pixels instead of %? This post may be of help : http://forums.silverlight.net/p/232055/569580.aspx[^]

Can you help me with how to use covariance contravariance for the example below? I am calling a WCF service and want to convert List object returned from service to List object in my wpf app. How to do that?

EmployeeSrv.EmpClient EmployeeSrvc = new EmployeeSrv.EmpClient();
List lstEmployee = new List();
lstEmployee = EmployeeSrv.GetEmployeeDetails();
List lstEmpWPF = lstEmployee; //This errors and here covariance has to be used

I am writing a layered WPF application and want to call a WCF service. The method is below. I have Presentation - Business - Service and DataAccess layer. Can you please suggest which layer the below code should be written? Should it be in Business or Service layer? I am not sure even if there should be two different layers - Business and Service. What do you think?

public List GetUserList()
{
EmpSrv.Client EmployeeSrvc = new EmpSrv.Client;List lstEmployee = new List

Jurgen, Thanks a ton! I used the same List which is used in the WCF service instead of creating List in my application separately like below. Eservice EmployeeSrvc = new Eservice(); List lstEmployee = new List(); lstEmployee = EmployeeSrvc.GetEmployeeDetails();

Thanks Pravin. You pointed out not to write redundant code and that is excellent. But I have a question here. When following layers, do we not have to add the reference of Business in DAL, Presentation in Business etc. so that the flow will be maintained. If Business project is added as reference on all projects, would the layered architecture model not be affected?

WCF Service returns List. I call from wpf app and have User class which contains the same properties as Employee class in wcf service. Eservice EmployeeSrvc = new Eservice(); List lstUser= new List(); lstEmployee = EmployeeSrvc.GetEmployeeDetails(); I get the error "Cannot implicitly convert type .." I am not sure how to convert the WCF return list to List in my wpf app. Please help!

I have created a web app with 4 layers : Presentation - Business - Services - Data. I have Business.Entities project which is added to Business layer and have Employee class in it. I also have DataAccess.Entities and Presentation.Entities and have added Employee.cs in there also. Now in project references I have added Presentation project reference in Business, Business project reference in DataAccess. Is this approach correct? My Question is, Should Employee.cs class be added to each project entities like I did above or should Employee.cs be added to only Business.Entities project and Business.Entities proj reference be added to all projects? I got this question because the 2nd approach was used in a project I downloaded from internet. Please help.

Somebody has created a class library project added to the solution by name Sample1. I do not know what kind of project template(here it is class library) is that. How do I find out what project they have added? Hope this is clear.

On the solution, there are many projects in an existing application. One of them is an asp.net web application, another one is class library and another is Dynamic data web application. How can I find what project is it? I looked in the properties but could not find it. Please help.

Everything has a necessity and I wanted to clearly communicate that am not a beginner. Please ask why this is needed if you are interested to help or opt to stay out. There will be somebody else who will be willing to help. When I have posted a question on a forum, it clearly means I am looking for a solution. This is what am trying to achieve. Ajax control, collapsible panel extender(cpe) needs to expand a panel containing a repeater control and load data into repeater when the panel is expanded. I found that there is no server side click event but there is an expand-collapse javascript handler. To call server side code from AJAX, Pagemethods can be used. <asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server"> </asp:ScriptManager> [System.Web.Services.WebMethod] public static DataSet GetContactName() { DataSet ds = new DataSet(); XmlDocument doc = new XmlDocument(); ds.ReadXml(System.Web.HttpContext.Current.Server.MapPath("App_Data/Group.xml")); LoadData(ds); } public void LoadData(DataSet ds) { DataSet ds = GetContactName(); repeaterGroup.DataSource = ds; repeaterGroup.DataBind(); } I am not able to access LoadData from GetContactName(). Any help on this would be greatly appreciated.

[System.Web.Services.WebMethod] public static DataSet GetContactName() { DataSet ds = new DataSet(); XmlDocument doc = new XmlDocument(); ds.ReadXml(System.Web.HttpContext.Current.Server.MapPath("App_Data/Group.xml")); LoadData(ds); ????? } I need to bind this ds to a repeater control. public void LoadData(DataSet ds) { DataSet ds = GetContactName(); repeaterGroup.DataSource = ds; repeaterGroup.DataBind(); } My question is, how to call LoadData from above webmethod. LoadData() method is not recognized from the webmethod.

Thanks Mark. Web platform is what I am using. I found the ajax collapsible panel but not sure if something better can be used here.

Which control can I use for displaying bulleted list? > A > B > C When I click A, there should be a gridview/panel which will be displayed. Thanks

insert into #temp exec dbo.MyStoredProc 89,1 (MyStoredProc requires 2 integer parameters.) The above works fine but in my stored proc where I write this insert statement, I need to create the #temp table and MyStoredProc results in 100 columns. Only 5 columns have to be stored in #temp. I need something like below. (As you would know, am making it clear, below does not work!!) select col1,col2,col3,col4 into #temp exec dbo.MyStoredProc 89,1
