[swapnilbhavsar]

Hi I am creating one application in ASP.NET using the c#. In my application I use the Text Box with multi line,on that I create the Context menu to select the text in that text box. I am able to cut the selected word from that text box but i want to Undo that cutted word by selecting the option in the context menu. So I want to know how I can capture the position of mouse click of the context menu in my text. In short I want to make the functionality as "Cut" And "Undo Cut" in the normal notepad. Swapnil Bhavsar
