Hi cecilia,
Thank you for posting query to us.
Our Syncfusion GridDataBoundGrid has direct support for multiline cell. For multiline cell , you can handle Model.QueryCellInfo for GridDataBoundGrid and set the style properties AllowEnter, AutoSize and WrapText to true(this is true by default).The property AllowEnter should let you type an enter key into the cell. Autosize should allow the cell to grow as you type.
Below is the code snippets:
private void Model_QueryCellInfo(object sender, Syncfusion.Windows.Forms.Grid.GridQueryCellInfoEventArgs e)
{
if(e.ColIndex==3 && e.RowIndex>0 )
{
e.Style.BackColor=Color.LightPink;
e.Style.AllowEnter=true;
e.Style.WrapText=true;
e.Style.AutoSize=true;
}
}
Please refer the sample which illustrates the above said feature:

Kindly let us know if you need any further assistance.
Best Regards,
Jeba.
