'System.ComponentModel.CancelEventArgs' does not contain a definition for 'FormattedValue' and no extension method 'FormattedValue' accepting a first argument of type 'System.ComponentModel.CancelEventArgs' could be found (are you missing a using directive or an assembly reference?)

Without the releveant code fragment, it's difficult to tell, but probably what you have done is tried to use a standard CancelEventArgs when you meant to use your own derived type, which includes FormattedValue as a property or method.
Either that or you didn't mean to use the EventArgs at all, but a DataGridViewCell reference instead...did you mistype "e" for "c" by any chance?

ni i type it as e sir code is
private void dataGridView2_Validating(object sender, CancelEventArgs e)
{
if (String.IsNullOrEmpty(e.FormattedValue.ToString()))
{
MessageBox.Show("Cell not be empty. Please insert value.");
e.Cancel = true;
}
}

CancelEventArgs does not contain any information about your DataGridView, much less the cell.
You need to change your handler to refer to the appropriate dervived class: DataGridViewCellValidatingEventArgs for CellValidating for example.
See MSDN re the appropriate Validation event: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellvalidating.aspx[^] for Cell validation, for example.

It's not telling you porkies. FormattedValue is not a member of System.ComponentModel.CancelEventArgs. If you look here[^], you will see that the only property that is added is the Cancel property.

i am not understand ur language

It's not telling you porkies means that the message is telling you the truth. It's from something known as Cockney rhyming slang, where Pork Pies = Lies, and so porkies. And, as I said, FormattedValue doesn't exist in that class. I don't know how much plainer I can make it - it's your code that's wrong, not the compiler.

Hi,
Am using one dll in my application.
This dll contain one internal class which is used to show popup winform.
Am displaying this popup form.
This popup form contain 2 linkLabel, i want to set the visible property of this linkLabel as false, i cant directly access this control because of its protection level(Private) in Internal class in a assembly.
So could any one tell me how to do this.?
This is my code.
Assembly assembly = Assembly.Load("HS.Satis.Client");
Type myType = assembly.GetType("HS.Satis.Client.AuthenticationForm");
FieldInfo fieldInfo = myType.GetField("_changePasswordLinkLabel" ,BindingFlags.NonPublic | BindingFlags.Instance);
i can manage to get the field information which is available in internal class into fieldInfo variable, from here, how can i set the visible property of
_changePasswordLinkLabel as false using reflection.?

..setting the field is done is a similar way as getting it's value. GetValue[^] has an example in the documentation, off course.
So, you ready to explain whom this "Satis" client is that you're going to hack to steal their clients passwords?

I know about setvalue, but before setting a value, i need to track the visible property of a field right.
but here i couldn't able to get the Visible property of a field _changePasswordLinkLabel
PropertyInfo propInfo = fieldInfo.GetType().GetProperty("Visible");
propInfo.SetValue(myPropertyInfo, false, null);
I tried something like above, but propInfo is returning Null, dont know how to get the visible property of a field using reflection, am stuck here.
Could you pls tell me how to get the Visible properties of a field
_changePasswordLinkLabel
Ans Satis is an assembly name am using in my application and its full name is like this "******.*******.satis.client.dll"
and we can use this assembly only in our internal projects, so didnt displayed the complete name of the assembly here.

..simple, you enumerate all properties. If you find one called "Visible", you got the right one.
Make sure you're actually reading from readable properties, and write to writeable properties. And no, I can't help without you showing the offending code. These are snippets that show a bit reflection and a bit of some dll you're trying to hack.
..which brings us to the next question; do you have the original authors' consent?

What comes to mind is that if you have an instance of the Form you want to affect, then why are you loading an Assembly? 
|
|
|
|
|
is it possible?
for example, form1 got a lot of control and whenever showed, the controls load one by one.
this is very ugly. 
|
|
|
|
|
Display a splash screen or a progress bar[^] until the form is loading initially.

|
|

put the splash screen on form load?

Hi
I used the GetAsyncKeyState API function
Private Declare Function GetAsyncKeyState Lib "user32"
(ByVal vKey As Integer) As Short
My problem is that I have to know if the key that pressed is the English or other languages to print out the key which is pressed
thank you in advance to helping me out
|

A key isn't pressed in any language; a key is merely a key, and a combination of keys produces a character. You cannot map key 'a' to character 'a', because it might be that the user is typing 'A'. Alt-A doesn't even count as a character.
Hence, you'll have to figure out what the character the keys would map[^] to.

Your sig is all wrong in this forum; as the OP posted some VB code (you didn't notice?) he should use a translator the other way around...
