Hi! Experts,

please do the needful on my query.

In RichEditControl, i'm accommodating 24 lines(horizontally).
When 25th line enters, the 1st line should become as non editable. similary whenever new line is adding on the bottom, the top most should go in non editable part. How to solve this ?
Please give me the idea or sample if possible.

Thanks
Sam

I looked for it in google. there is no built in solution. But you can fix this issue programmatically. Before you let the character to be printed make sure they are not your readonly part area....

In more detail. At beginning keep your readonlyarea=0, when your character count read to 25, then change your read only area to 25 i.e. readonlyarea=25. and check if the user cursor position is less than readonlyarea, if so, don't let the character to be inserted. this way keep incrementing your count.
