When I enter a bad-format value (i.e. - a string into an integer item), I get an error message. If I click "OK", the bad value stays until I change it. If I click "Cancel", the original value is back. I want to control the buttons so clicking "OK" will also set the original value back instead of showing the bad value like the cancel button. How can I do that? c# winforms validation propertygrid share|improve this question edited Apr 22 '14 at 13:05 huMpty duMpty 9,42483270 asked Apr 22 '14 at 12:09 TamarG 1,20031744 3 I can't help but ask: why? –Crono Apr 22 '14 at 12:11 1 You'd have to write your own TypeConverter and catch the problem in its ConvertFromString() method. This is where the value of using PropertyGrid rapidly starts to diminish, when you see yourself wanting to change its default behavior then it is time to create your own data entry form. –Hans Passant Apr 22 '14 at 14:14 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote I'll join @Crono on that, why do you want that what you want? If you would ask how can I remove that dialog, then I could answer use own TypeConverter: public class IntConverter : TypeConverter { public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType) { return true; } public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType) { return true; } public override object ConvertFrom(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value) { if(value is string) { // try parse to int, do not throw exception } return 0; // always return something } public override object ConvertTo(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object v

Windows Forms > Windows Forms General Question 0 Sign in to vote I use a PropertyGrid to show a business object in my application. The business object throws exceptions if the user tries to enter an invalid string inside the PropertyGrid. The PropertyGrid shows two different behaviors in this case: If a default TypeConverter is used the PropertyGrid shows anbuiltin error message dialog. If a custom TypeConverter is used the PropertyGrid doesn't handle the exception. This happens only in Debug mode. How can I catch these exceptions and suppress the builtin error message dialog of the PropertyGrid? Thursday, Septemb

Finding Grid Positions in a Property Grid Hi there, [reposted from microsoft.public.dotnet.framework.windowsforms] In C Sharp, I want to find the Y position (center, or top and bottom would do) of the individual rows of a PropertyGrid. Is propertygrid error that possible? In other words, I want to be able to find out the Y position, relative to the top left of either the PropertyGrid or its container, of the properties listed, for each item listed, or even better for an individual item. I did find I could do the following to get something : Point p = new Point(0,0); Control ctrl = propertyGrid1.GetChildAtPoint(p); The ctrl propertygrid error message returned is a restricted object of type System.Windows.Forms.PropertyGridInternal.PropertyGridView I'm currently poking around in that to see what I can find, but it's tricky, and most of it is protected or internal code, and since it is restricted it could change in the future, so hopefully someone has an idea or some insight...

Controls and Databinding, PropertyGrid - How do I display a custom error message - different from "Property value is not valid" Top Hi I have implemented a PropertyGrid that displays a list of properties from my own implementationof a ICustomTypeDescriptor. I have the TypeConverters and UITypeEditor working fine. Now I am trying to limit values entered into a property to a value between 1 and 10. I am able to check for the value range within the TypeConverter's CanConvertFrom method and throw an exception from within that message. Throwing the exception from that method displays the standard message box with the title"Property Window" and the message "Property value is not valid". What I want to do instead is to display my own message box which displays text like "The value should be in the range 1 and 10". Anyone - Any idea how I would go about doing this I appreciate any pointers related to this. Regards, Windows Forms5 tkerns Posted: Windows Forms Data Controls and Databinding, PropertyGrid - How do I display a custom error message - different from "Property value is not valid" Top What code does CanConvertFrom have that throws the exception Tony athadu Posted: Windows Forms Data Controls and Databinding, PropertyGrid - How do I display a custom error message - different from "Property value is not valid" Top I have coded ConvertFrom to throw exceptions intentionally. But the message that PropertyGrid .NET code display when I tab out of the proeprty field is very generic and is not that intuitive. It shows up with a title bar "Property Window" and the text "Property value is not valid" with a 'Details' button. When I click on the 'details' button, only then does it displays the text from the thrown exception. Instead, I want to display my own message box with different title bar and content. Thank you Tony for your interest and reply. Here is the ConvertFrom
