Why you have a DataTable without a DataSet? It does not matter. I dont know, why the RowFilter stops working, but try to use the Select-Method from DataTable instead a DataView.RowFilter.

Hello Never heard of it!! Why don't you put a label above the DataGridView?:-D Regards:rose:

Hello I'm sorry my reply came very late, but your email notification arrived to my just now!! You can't acess ctl this way because you've declared it as a local variable in a method. Declare it as a public member in your class, and access it like MyCustomColumn.ctl.Click for the click event as an example. I don't know if my reply would help you or it came too late, but forgive me. Regards:rose:

Hello If you've created that custom control then you control its events. You can do this in two approaches: 1- Make a custom event in your custom control. Handle whatever events you want to handle of the button and textbox private inside your control. From these handlers, fire the public event. Now handle that public event in your form. 2- Just declare your button and textbox as public members of your control. Then you will have access to their events as well. Programatically only of course -ie. you may not access their events using the PropertyGrid by default-. Regards:rose:

When you click on a toolbar button, the control that has the focus doesn't lose it, and thus Validating/Validated events are not generated. My solution goes to great length to ensure that the focus is given back to the control that has it, so that it acts the same as you. Your solution simply takes focus away from the currently focused control, and doesn't give it back. I did try something similar before getting to my recursive solution, but I don't remember the details. I took your code and gave it a try, and this is what I came up with: private void toolBar1_ButtonClick(object sender, ToolBarButtonClickEventArgs e) { if(!ValidateFocusedControl()) return; if(e.Button == toolBarButton1) MessageBox.Show(this, "Button 1 clicked!"); else if(e.Button == toolBarButton2) MessageBox.Show(this, "Button 2 clicked!"); } The heart of if is that call to ValidateFocusedControl: protected bool ValidateFocusedControl() { bool result = true; Control ctl = ActiveControl; toolBar1.Focus(); if(!toolBar1.Focused) result = false; ctl.Focus(); return result; } I gave it a try and it works as expected, even with controls inside tabpages for example. -- LuisR Luis Alonso Ramos Intelectix - Chihuahua, Mexico Not much here: My CP Blog!

Try to add reference to System.Design.dll... this lib doesn't shows on Visual Studio when you go to Add Reference. So you must to browse it on Framework folder Wender Oliveira .NET Programmer

You should not use spaces when Naming your Database objects (tables,columns, SP, etc..) rename your columns and replace space with _ (ex. FIRST_NAME)

You can, check out the InstalledFontCollection[^] class. - Nick Parker   My Blog

Almost all the controls in System.Windows.Forms encapsulate their Windows common controls equivalents. Not all of these controls support all the notification messages that raise events in .NET. The ComboBox, for instance, pops up and hides its scrolling popup window used for the drop down on WM_LBUTTONDOWN and is not double-click aware. If you want to make it so, you're going to have to extend the ComboBox controls in .NET, override WndProc, and handle many of these messages yourself. To handle messages like WM_LBUTTONDOWN though, you might have to use an IMessageFilter. Anyway, you'll have to capture this message before it goes to the base class's WndProc method (which you should call base.WndProc(ref m) after your code) and start a timer. If the timer elapses, call SendMessage (which you'll also have to P/Invoke) with the original data that came with the WM_LBUTTONDOWN message. If the user clicks again before the timer elapses, then you've got your double-click event and should throw-out the WM_LBUTTONDOWN message (i.e., don't send it). The easiest way to raise this event is to just call base.OnDoubleClick, which will raise the DoubleClick event. Microsoft MVP, Visual C# My Articles

Hello Marc!! Infact i started work on the deisgner few days back. I used the same way as Rojer told. I have made my own custom control classes hierarchy and renedring them both on design time and at preview. Here i posted because( i was studying Java Reflection API's in previous days there we can have all classes , properties methods etc i htought that if anyone have used same kind of thing in .net (if available)) so that if i could found a better way but i came to know htat i am going in right direction. You said about "Collboration"... Sure ...why not...:) sorry for my bad English.

There is System.Windows.Forms.FolderBrowserDialog in .NET 1.1 and up. For applications targeting .NET 1.0, you'll have to create a look-alike or encapsulate the SHBrowserForFolder API. There are several articles here on the CodeProejct site that discuss the latter option. The component I mentioned first is very easy to use, just like the OpenFileDialog and SaveFileDialog components. -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?
