I have a requirement that I need to develop a custom textbox control which should support the functionality like:
1. Should display the Default Cursor as Cross Cursor
2. Textbox should be displayed like excel sheet cell (specific to cell) and when user will click the TextBox it should be selected but can not be entered any data inside.
3. Context Menu should be displayed with some information while double clicked on the TextBox but should not be edited the textbox.
4. Context Menu should be displayed if right click on the TextBox
6. TextBox should be on entry mode if user presses any ALPHNUMERIC key from Keyboard.
7. DataValidation should be there when user enters any data.
Can anyone help me on this how to develop such kind of control or May be somebody has already done those things and can give me a hint...
Thanks in advance for the help.
