  Hi,
  we cant stop the paint method. so it is possible do like outlook2007 reminder u have any idea about develop control like that

  In my mind, paint wouldn't effect datasource of the DGV

  the repaint make your data disappear I think it because you haven't save it back to the datasource,

  so would you mind post some code can it would help our supporters to understand your problem clearly

  Hi I am just wandering did you ever get this working
  
  I am looking do achieve something similar myself but I am fairly new to C# and I am struggling somewhat... Have you posted your control on sourceforge or similar as i would like to try something like this in my app
  
  thanks

  So, do you use databinding for the datagridview if so , you need to check whether the datasource table for this datagridview is changed after you enter data,

• Cam70

  Hi , as we know, when we use DGV,

  we select cell (click or double click the cell)

  the enter form keyboard,

  but I am puzzled what do you means disappear are you mean your DGV always have only one row

  would you mind post some code here we can have a look
