I'm a looking for a textbox (not multiline) custom control that helps to build math equation and also validates the same. I need to use this control in DataGridView equation column. Whenever user double clicks on equation column, it might need to bring a window to build math equation.

I was looking for a simple textbox, I don't need all math functions. Inaddition, textbox should validate open, close parentheses, operators priorities etc when calculating. I haven't got to this yet, I'm working on someother things. I think, Imay write custom textbox,if I do not find what I was looking for.

Thanks,

Hello,

Thanks for your feedback.

I am not sure what operations and math functions you need, but you still can take the logic from the articles suggested by Gnanadurai.
