Hi,
I tried setting the datacontext to the control, the grid, from another class property using the mvvm model and countless variations of . & / still this refused to work in Silverlight.
If anyone has a working example id be interested in seeing it!
I managed to get it working however by doing it this way:

Thanks,
Chas

I want to create a theater management system in which I have to dynamically add the seats as present in the table of database. Imagine a theater where there are seats from Row A to J and seat number 1 to 10. I want to make sure that if the seat is booked, I have to show it Red, if its vacant, I have to show it in green and if its disabled, it must be grayed out. I also want to create the table for such layout in Silverlight... Any suggestions?
Always Keep Smiling.
Yours Pankaj Nikam

Homework - we've had this question at least twice before, and we don't do homework for people. It's not that we feel we're too good to do it, it's that you won't learn anything if we do it for you. Part of being a programmer is being able to anaylze the problem, establish requirements, create the design, and implement the solution by developing the code.

Hi,
I have to do a validation to check the duplicate records in my application, with the use of Identifier name..
am getting a reply from database in the form of SOAP Message(XML format), through Java, means java is passing an identifier name for that particular application, by using this Identifier only, i have to do the validation, so will u pls tell me how can i do this by using that identifier name...
|

You haven't provided anywhere near enough information for us to be a help. What type of application is it? How are you storing your data - for instance, are you using a Dictionary to host the items?

See am pasting my code here, am creating a keberosed connection to connect to database through Java, the code is like this
KeberosedConnection kc=new KeberosedConnection();
kc.CreateNewReportTemplateType(strIdentifier, "ReportTemplateTypeName", "Description");
am passing the Identifier name through strIdentifier, through which i need to perform validation and perform all the action, related to my application and am passing the report template name(from TextBox) and description through "ReportTemplateTypeName" and "Description" respectively in the above function..
The below code is used to pass the request through SOAP Server to communicate with Database.
public void CreateNewReportTemplateType(string strIdentifier, string ReportTemplateTypeName, string Description)
{
try
{
var sb = new StringBuilder();
sb.Append("<ReportTemplateType xmlns='http://xml.abc.com/ns/abcjava/lrm'>");
sb.Append("<Identifier>");
sb.Append(strIdentifier);
sb.Append("</Identifier>");
sb.Append("<ReportTemplateTypeName>");
sb.Append(ReportTemplateTypeName);
sb.Append("</ReportTemplateTypeName>");
sb.Append("<Description>");
sb.Append(Description);
sb.Append("</Description>");
sb.Append("</ReportTemplateType>");
SoapMessage request = BuildRequest(sb.ToString());
SoapMessage response = ExecuteRequest(request);
}
Assume that the identifier name is "RPNew", so by using this identifier name only,because through Identifier only am communicating with Database, i have to do the validation for checking the duplicate record while am saving the new report...
Hope this will help in Understanding the question better, so shall i expect a answer with a sample..

First of all, what does this have to do with Silverlight or WPF? Secondly, you are looking to the validation at the wrong location - the only place you can effectively do this is at the database end, which will require the validation to be triggered from that side. You have to do it there because of timing issues - suppose you have two people who both enter the identifier Bob and submit it at the same time; they could both very well pass the validation, only to fail the insert because there is now a conflict.

Third - that's not the way this site works. We generally don't give full samples here - we help to correct code and to suggest things, not write the whole things ourselves.

Hi!
New to silverlight, i have a problem.
I have created a service to connect to a database and i want to call it many times, the problem is that
string a and string b is executed before the event is triggered?
in the event i have code that catches the result from the service and i want to save it to the string a and then call the same service again and save that result to string b.
but i can't do that if the event isn't triggered each time
any ideas on how to solve?
main(){
serviceclient x = new serviceclient
x.xxx_completed += the event
x.getdataAsync();
string a;
string b;
}
void event ()
{
code to get data
}

Implement all string saving logic inside the void event() method.
Call the service again after you obtain the result if you have to.

I am doing some string operations in the event().
but the problem still is:
in the void event () i define 2 dynamic keys (in a property) depending on the input parameter to the service
after i have done this i use the keys in the other method before calling the service again to retrive two other keys.
but the methodcall_x(keys) is executed before the event is triggered
and keys = null so i can't call the service again.
class x {
MAIN{
Servicecall()
methodcall_x(keys)
}
viod the event(){save result to a property}
}

What you need to do is to use an Action to return to MAIN once event() method is executed.
Move the methodcall_X(keys) in this Action's handler.
For more info on Actions, check out MSDN.

<i:Interaction.Triggers>
<i:EventTrigger EventName="SelectedItemChanged">
<i:InvokeCommandAction x:Name="abc" Command="{Binding Path=test, Mode=TwoWay}">

Hello,
I'd like to display my own WPF window at start up, which means I don't need standard splash screen. But, I'd like exactly the same behavior as splash screen. It means my own WPF window should appear right after the aplication started and stay visible until the main application window shows up.
Thank you in advance.
Regards,
Goran
