Silverlight, connecting service.cs and XAML.cs for database -

-

i've found sample showing how connect sql server (a local mdf), uses databinding, how can use sql in normal way (insert, select, update, delete..., sqldatareader, without binding), think sql staff should performed in service.cs, how can use sql xaml.cs? here service code:

and here service.cs:

public class servicecustomer : iservicecustomer {     public clscustomer getcustomer(int intcustomer)     {         sqlconnection objconnection = new sqlconnection();         dataset objdataset = new dataset();         sqldataadapter objadapater = new sqldataadapter();         sqlcommand objcommand = new sqlcommand("select * customer customerid=" + intcustomer.tostring());         objconnection.connectionstring = system.configuration.configurationmanager.connectionstrings["connstr"].tostring();         objconnection.open();         objcommand.connection = objconnection;         objadapater.selectcommand = objcommand;         objadapater.fill(objdataset);         clscustomer objcustomer = new clscustomer();         objcustomer.customercode = objdataset.tables[0].rows[0][0].tostring();         objcustomer.customer = objdataset.tables[0].rows[0][1].tostring();         objconnection.close();         return objcustomer;     } }

and page.xaml.cs:

public page()     {         initializecomponent();         servicecustomerclient obj = new servicecustomerclient();         obj.getcustomercompleted += new eventhandler<getcustomercompletedeventargs>(displayresults);         obj.getcustomerasync(1);     }     void displayresults(object sender, getcustomercompletedeventargs e)     {         layoutroot.datacontext = e.result;      }

how can insert value dayabase right page.xaml.cs? how can make connection between service , xaml objects , functions?

thanks

the page.xaml.cs file not autogenerated in standard silverlight project (beyond it's initial creation via template), changes make class persist.

if current project autogen of xaml classes can use partial class feature of c# partial classes in c# guide add class without worrying autogen remove additions.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
