Actually the DataGrid automatically shows multiline data, separated by \n. What you need to do is only adjust the height of the row so that you can see the whole text. Just for a test, enter programmically a value like "line1\nline2" in a cell in the data grid and resize the row to see both lines.

If you need to edit multiline values, then you have to use a custom table style and column styles and use the property DataGridTextBoxColumn.TextBox.Multiline property to set the text box, which edits the data, to accept multiline.

hi.

what i mean is, when the data length exceeds the width of the column, it automatically displays it to the next line (in display mode not in edit mode).

Thanks.

OK, this is called word wrapping. I think you can implement it like this: intercept the text changed and column resizing events and make manually calculations how long the text is and how wide the column is. Then put the new line characters at the appropriate positions (don't forget to remove old ones...)

Here is an example: you have the size of the column so big, that 4 letters can fit in it. You have the string:
abcd efgh ijk
so you make it:
abcd\nefgh\nijk - 3 lines
Then the user resizes the column so that it now can show 9 characters, so you make the string:
abcd efgh\nijk - 2 lines
Somewhere in the background you will need to keep the original data....
