Hi,
I'm trying to create my own numeric textbox that will handle decimal as well as whole number values. The concept is, unlike the regular textbox, this one will accept a value of 'Double' data type and show it with proper formatting e.g. Leading Digits, Digit Grouping etc. When the textbox value is called, it returns the actual 'Double' data type value. The entire thing is done through the 'Text' property; wherein the regular 'Text' property...

How can I detect the click event of the close (X) button at the top right corner of the control box of a form/window? Please note, I don't want to know about CloseReason, FormClosing, FormClosed or stuffs like these, unless they are inevitable. I exactly want to detect if the user clicked the X button of the form. Thanks.

I am inheriting my own datagridview (say MyDataGridView) from the standard datagridview control. What I want is that certain properties of MyDataGridView should have a different default value than what its base have. For example, AllowUserToAddR ows, AllowUserToDele teRows, AllowUserToResi zeRows properties should have the default values of False; so that when I drag MyDataGridView into a form in the IDE, the default values shown in the properties grid...

Hi,

I have a simple winform which creates has in it a NumericUpDown, two group boxes and two buttons. The code then dynamically inserts a number of NumberBox objects into one group box and a pile of labels into the other.

(A numberbox is just an overloaded TextBox - details are at http://www.all-the-johnsons.co.uk/csharp/numberbox.html)

If I click the NumericUpDown, the code inserts new boxes and also...

Is there any predefined property by which I can set the DisplayFormat/DisplayStyle of a textbox? Suppose I want a textbox to hold the actual value 888888888888.88 and show it formatted as 888,888,888,888 .88. In short it should hold 'Double' data type value and show it with thousand separators and decimal places upto two digits. If text is cleared from the textbox, it should have 0 as value and 0.00 as displayed value. Also the number of digits in...

Hi,
I wish to hide the group tree of the crystal report viewer programatically .
Intellisense denied any "DisplayGroupTr ee" property of the control!
A little googling yielded the fact that in VS 2008 the "ToolPanelV iew" property serves the purpose.
The intellisense denied even this property.
I am using VS 2008 and the build is with target 3.5 framework.
I feel betrayed.
Please help!...

Hi There,

I'm having a really strange issue with the DataGridView control in a VS2008 / .NET 3.5 winforms project. I have a simple form with a grid.

After the form finishes loading the code didn't work i.e. the cells are not set to...
