I have a requirement to add dynamically a list box or checkbox to a propertygrid at runtime. I do not know at compile time what type of property items to be added to property Grid. I am able to achieve to add dynamically a simple property item like a text by overriding the "PropertyDescriptor" Class in my customdescriptor class. But how to add in similar way a checkbox or listbox to propertygrid dynamically ? I was not successfull till now. But I can achieve the same thing for example adding a checkbox property item at compile time(without overriding PropertyDescriptor) by using UiTypeEditor like: public class CheckBoxTest : System.Drawing.Design.UITypeEditor { public override bool GetPaintValueSupported(ITypeDescriptorContext context) { return true; } public override void PaintValue(System.Drawing.Design.PaintValueEventArgs e) { System.Windows.Forms.ControlPaint.DrawCheckBox(e.Graphics, e.Bounds, ((CustomProperty)e.Context.Instance).checkValue ? ButtonState.Checked : ButtonState.Normal); } } But If I try to achieve the above to be executed at runtime by overriding "PropertyDescriptor" These functions are not called. Can anyone have any idea ? Thanks, Rajan

I am using a CutomTask Pane in Excel as an C# .NET ADDIN. The custom task pane has a close button(X) at the right corner. I need to not allow the user to close the Task Pane or disable the Close button(X) . Can anyone have any idea ? Is there any way to trap the close(X) button and prevent user from closing it ? I tried to trap the VisibaleStateChange event handler of Custom Task pane and try to show it again when user clicks the X button. But I am not successfull. I am using the CreateCTP() COM function to create a custom task pane. Thanks, Rajan

I am trying to add propertyitem dynamically to property grid. For example If I want to add a property Item Like a text box which takes "String name" as variable how to add dynamically to property Grid? I can do the following to add the "name" text box at static design time: public class PropertyGridProcessDesigner { [Editor(typeof(PropertyGridProcessDesigner), typeof(System.Drawing.Design.UITypeEditor))] public string Name { get { return name; } set { name= value; } } } But how to achieve the same above thing at run time ? Do we need to create dynamic classes to add Property Item ? If so, can anyone please share any information you have ? Thanks, rajan

I tried Gareth , focusing, activating treeview But still the keydown control goes to ContextMenu. I tried to Minimize and Maximize the form programatically to make context menu lose focus but it is not working. Thanks

My doubt is After the context menu is displayed, the context menu is still there even after I close it explicitly. When I minimize and maximize the form the keydown event is going back to treeview. But I am not able to achieve this programatically.

You are right Gareth. It automatically appears as you said. But in certain situations for functional aspect I need to show or hide it. But the problem comes when I press key down after I show the context Menu. The control after that for keydown always goes to context menu. Why is not coming back to Treeview for Keydown.

I am not using any event to display the context Menu Strip. It is declared as private System.Windows.Forms.ContextMenuStrip DimensionModify; in class designer of form When I add it in visual designer. I am using DimensionModify.show() or DimensionModify.Hide() to display or hide the contextMenu .

Adding one more to thread... When I do the above and press Keydown in Treeview the application throws an exception saying arithmetic underflow or overflow error? Do you have any idea of this ? Thanks, Rajan

Tnanks for your reply Gareth. I do not want anything to happen when I press Key down. I have added the contextMenuStrip in form at design time. I have displayed items in it and using the mouse click event for functionality. But when I press Key down event in context menu and when I go back to Treeview and press Key down the control is going to Contextmenu. It is supposed to go to Treeview. I am surprised why in keydown event control is going to Contextmenu when It has been closed . Hope you have got my problem .. Regards, Rajan

I am using a contextmenuStrip in Treeview . The problem is When 1. Open Context menu strip by right clicking TreeNode. 2. Do not select any item in Context Menu Strip . 3. Select any TreeNode in Treeview . Now Context Menu Disappears. (This is fine) 4. Now press any keyboard Key . Nothing is working . The control is still with ContextMenuStrip popup menu even though it is has disappeared. How to solve this problem ?. How to disable the Key down event in ContextMemuStrip ? I am able to trap PreviewKeyDown event for ContextMenu but not able to diable Key Down event in Context Menu.

I am using a property Grid with a check Box displayed as one of its item. I am able to display Check Box and check/Uncheck Items. But the problem is I am also getting a drop down List box with True/false along with check box. I need to get rid/hide this drop down List Box . Can any pne please let me know for the soultion if possible ? the code I am using for displying Check Box is: [Editor(typeof(CheckBoxInPropertyGridEditorTwoPassCalc), typeof(System.Drawing.Design.UITypeEditor))] public bool TwoPassCalculation { get { return twoPassCalculation; } set { twoPassCalculation = value; } } public class CheckBoxInPropertyGridEditorTwoPassCalc : UITypeEditor { public override bool GetPaintValueSupported(ITypeDescriptorContext context) { return true; } public override void PaintValue(PaintValueEventArgs e) { ControlPaint.DrawCheckBox(e.Graphics, e.Bounds, ((GeneralDimensionClass)e.Context.Instance).twoPassCalculation ? ButtonState.Checked : ButtonState.Normal); } }
