I have a MasterDetail Form where in detail is a datagridview. In Master Form a comboBox of class_IDComboBox
On the other side in Detail Gridview a comboBox of StudentName, which
fill by and GetBy a class_IDComboBox.ValueMember on Form Load, and
Navigation Move Next or Previous,
I bind the combo Box of datagridview and it is working fine on Load Form, becuase on Load I put this code in last line.
int cb1 = Convert.ToInt32(class_IDComboBox.SelectedValue );
this.table_Student_InformationTableAdapter.FillBy(this.dataSet_View_Student_Name.Table_Student_Information, cb1);
While that, when I cllick on Move Next button ," DataGridview ComboBox value is not valid " error is occured.
I put this code in MoveNext button click event, becuase when I will
move the record the GridviewCmboBoxVlaue will be the Database value.
int cb1 = Convert.ToInt32(class_IDComboBox.SelectedValue );
this.table_Student_InformationTableAdapter.FillBy(this.dataSet_View_Student_Name.Table_Student_Information, cb1);
How to remove this error "GridViewCombBox value is not valid" in DetailGridViewComboBox
