I am trying to hide/unhide a calendar that I created inside a gridview. I would like to get it hidden when I click the "Update" option in the gridview. Now after click the "Update" the calendar comes up because I don't have any code defined.
I was thinking if I add some code inside the RowCommand event it could works but I was unable to find the control. I tried this but I got errors in the syntax.
Calendar Cal = (Calendar)Gridview.Findcontrol("Cal1")
Cal.Visible = false;
P.S. I created a button named "CalMABD" to bring the calendar up after click it I tried adding a "onclick" event but I have the same issue to findcontrol of the calendar.
Here is the HTML
<asp:templatefield headertext="MABD" itemstyle-horizontalalign="Center" xmlns:asp="#unknown">
<itemtemplate>
<asp:label width="60" font-size="Smaller" id="LabelMABD" runat="server" text="<%# Eval(" mabd")="" %>"="">
<edititemtemplate>
<asp:textbox width="60" font-size="Smaller" id="txtMABD" runat="server" text="<%#Bind(" mabd")="" %>"="" autopostback="true" ontextchanged="Deltaprojected_OnTextChanged">
<asp:calendar>
ID="Cal1" runat="server" OnSelectionChanged="Cal1_SelectionChanged"
BackColor="White"
BorderColor="#999999" CellPadding="4" DayNameFormat="Short" Font-Names="Verdana"
Font-Size="8pt" ForeColor="Black" Height="180px" Width="200px" >
<selecteddaystyle backcolor="#666666" font-bold="True" forecolor="White">
<todaydaystyle backcolor="#CCCCCC" forecolor="Black">
<selectorstyle backcolor="#CCCCCC">
<weekenddaystyle backcolor="#FFFFCC">
<othermonthdaystyle forecolor="#808080">
<nextprevstyle verticalalign="Bottom">
<dayheaderstyle backcolor="#CCCCCC" font-bold="True" font-size="7pt">
<titlestyle backcolor="#999999" bordercolor="Black" font-bold="True">
<asp:templatefield itemstyle-horizontalalign="Center" xmlns:asp="#unknown">
<edititemtemplate>
I will appreciate any help on this! Thanks

Hi,
Suppose I have a SqlCommand as follows:
SqlCommand cmd = new SqlCommand();
cmd.Connection = <my connection="">;
cmd.CommandText = "Insert Into MyTable (Name, Surname) Values (@Name, @Value)";
cmd.Parameters.AddWithValue("@Name", "David");
cmd.Parameters.AddWithValue("@Surname", "Larkin");
cmd.ExecuteNonQuery();</my>
This will end up with the following SQL being executed : "Insert Into MyTable (Name, Surname) Values ('David', 'Larkin')"
Is there any way to actually see the SQL that gets executed? Something like cmd.ExecutedStatement or similar?
Thanks,
dlarkin77

You can use sql server profiler to see actual query. I'm not aware of other ways to see it.

You have to look at the database to see what's going on. The Performance Analyzer will tell you what's going on because you can use it to watch the activity on the database.

I'll look into SQL Server Profiler and the Performance Analyzer. Thanks very much,

thanks

You seem to be missing information from your query - like the bit after t,. Could you please post that again? BTW - if you want something nullable, you can always put a nullable constraint in there, such as public class MyClass<T> where T : INullable.

You have to mention though that INullable belongs to the SqlTypes namespace, so it can't be applied to the standard C# nullable types.

Specify that the generic type has to be a value type, then you can make a nullable type from it:
public interface MainInterface<t> where T : struct {
public T? SomeMethod();
public void SomeOtherMethod(T? info);
}</t>
Despite everything, the person most likely to be fooling you next is yourself.

localization and Globalization translates a word or sentence in a predefined word or sentence but what should i do if i want to create text according to the pronunciation of the sentence or the word in any other language.
like
"How are you" is equivalent to "comment soyez vous" in French (France), and is equivalent "aap kaise hain" to in Hindi (India).
it can be done with localization and Globalization
but what if i want how are you to be write down in French (France) according to pronunciation and the entered text is not predefined or static it will be passed by user at runtime.

This is called translation and a pain in the *** even for advanced services like Babelfish[^]. Basically you have to examine all words, put them into a context, find a matching idiom and lots of other stuff to produce a good (in most cases yet still not perfect) translation.

Thanx Greeeg for ur reply but is'nt that the longest way to achieve the target,,,,plz suggest some short way.

You can of course translate word by word, but this will produce horrible results.
For good translations you need to take the context into consideration the words are in.
Also idioms have different meanings in other languages so translating them word by word will also not produce good results.

There is no short way to solve this issue. This isn't an easy or quick task to solve, so you shouldn't look for quick fixes.

ok,,,,,yes i think so

i tried with cryptEncypt and cryptDecrypt function. Below are the key function which i used to get the publc and private key from certificate
Please check my code.. it not working (its in c# .net)
// create 128 bit hash object
if (!WinApi.CryptCreateHash(hProv,
WinApi.CALG_MD5, IntPtr.Zero, 0, ref hHash))
Failed("CryptCreateHash");
// add passphrase to hash
byte[] keyData = ASCIIEncoding.ASCII.GetBytes(passphrase);
if (!WinApi.CryptHashData(hHash, keyData, (uint)keyData.Length, 0))
Failed("CryptHashData");
// create 40 bit crypto key from passphrase hash
// if (!WinApi.CryptDeriveKey(hProv, WinApi.CALG_RC2,
// hHash, WinApi.CRYPT_EXPORTABLE, ref hKey))
// Failed("CryptDeriveKey");
// Generate new key pair
//WinApi.CryptImportKey(hProv, keyData, (uint)keyData.Length, 0, 0, ref hProv);
// Get a handle to the key exchange key.
if (!WinApi.CryptGetUserKey(hProv, 1, ref hProv))
{
uint dwResult = WinApi.GetLastError();
// printf("Error %x during CryptGetUserKey!\n", GetLastError());
//goto done;
}
if (!WinApi.CryptImportKey(hProv, keyData, (uint)keyData.Length, 0, 0, ref hProv))
{
uint dwResult = WinApi.GetLastError();
}
if (!WinApi.CryptGenKey(hProv, WinApi.CALG_RC2, WinApi.CRYPT_EXPORTABLE, ref hKey))
{
uint dwResult = WinApi.GetLastError();
//MessageBox("Error CryptGenKey() failed.", "Information", MB_OK);
// return;
}
// if (!WinApi.CryptGenKey(hProv, WinApi.CALG_RC2, WinApi.CRYPT_EXPORTABLE, ref hKey))
// {
// Failed("CryptGenKey");
// }

Apologies for the vague thread title, the following is a tad complicated to summarise well. Anyway, enough excuses...
Lets say I have a multi tier application that consists of 1 client and 2 server applications (A & B). Both servers have remoting listener services each of which are entirely self contained and do not share any common sinks, both remoting frameworks contain a custom encryption sink (each of which are entirely independent implementations)
In my current setup, the client pushes all its requests to server A. Some of these are handled within A others require a server A to server B remoting call.
Now here's the problem:
When server A is invoked by the client and this requires a remoting call to server B the call from A to B fails with a CryptographicException. It seems that for some reason the A to B encryption sink is not being called, so when B receives the data it cannot decrypt as the format is invalid.
Does anybody have any ideas of what could be happening here?
p.s. Interesting if I code the client to remote directly to A or B then these calls work without any issues.

I think its a 'Serialization' issue.
I am not sure but, Try without encryption. If it still gives you error then its a problem of Serialization else your encription methods mismatched.

I've found this issue with double hop applications before. Something, and I could never figure out what, caused the code to fall over with an invalid key issue.

After much hair pulling I have found a solution to this problem, I am not particularly happy with it but it is a solution none the less.
After doing some further debugging it seems that when the A to B request is made the .NET Framework pushes this into the incorrect channel (i.e. the Client to A) as this channel has different sinks, when B receives the data it is unable to process it. Interestingly if I unregistered the Client to A channel the A to B call would work, obviously this isn't a solution as this then breaks all Client to A comms.
At first it seemed that the solution was obvious, make sure that the correct channel is used. After much googling I have been unable to find a method of doing this. I did however find alot of people with the same problem 
So the solution...
The server B remoting framework has a client library which is installed on A. This library contains all the methods that B exposes across remoting. The solution was to create a wrapper around this client library, on instantiation the wrapper creates a new AppDomain and loads the client library into it. I then use a marhsalled transparent proxy object across to call the client library. Doing this means that the new AppDomain on has a single TcpChannel registered and therefore the selection issue doesn't exist.
As always with these things there was a gotcha, which is if you leave the AppDomain unused for more than 5 minutes (default) the lease expires and the proxy fails. This can be fixed by, in the client library, overriding "InitializeLifetimeService" and returning null.
So, wrapper code:
public sealed class ClientLibraryWrapper
{
AppDomain clientDomain;
ServerB.Client.EntryPoint client;
public ClientLibraryWrapper
{
this.clientDomain = AppDomain.CreateDomain("ServerBClientDomain");
Assembly clientAssembly = Assembly.LoadFile(Environment.CurrentDirectory + @"\ServerB.Client.dll");
this.clientDomain.Load(clientAssembly.FullName);
Object obj = mhsClientDomain.CreateInstanceAndUnwrap(clientAssembly.FullName, "ServerB.Client.EntryPoint");
this.client = (ServerB.Client.EntryPoint)obj;
}
public int ServerBMethod()
{
this.client.ServerBMethod();
}
}
Client library code:
public sealed class EntryPoint : MarshalByRefObject
{
public override object InitializeLifetimeService()
{
return null;
}
public int ServerBMethod()
{
return 1;
}
}
