i am trying to set the value of a combobox cell with the following code:
gridcontrol1[gridcontrol1.RowCount, CurCol].Text = ti.defaultvalue;
where defaultvalue is a string.
I am getting a runtime error (invalid cast exceptions: Specified cast not valid)l

Are you using style.DataSource, Style.DisplayeMember, style.ValueMember to set up the combobox cell? If so, is your ValueMember a string? If not, then you should not be setting .Text. Instead set .CellValue = to the object (of the proper type).

i am setting it up as a combo box with following code
_g[_g.RowCount, CurCol].ChoiceList = ti.enumeration;
_g[_g.RowCount, CurCol].CellType = "ComboBox";
where ti.enumeration is a StringCollection
please let me know your thoughts.

Here is sample set up you described.
It seems to work OK. Do you have other settings like style.DropDownStyle or style.Exclusive or style.CellValueType that might be affecting this.
