datagridview combobox column tobe as a text box

[judithSampathwa]

hi there,

i had a question regarding this before as well.
i have a datagridview and it has three combo boxes, with one with form name and the other with employee name and the other just a selection. what i want to do is to make the form name combo box to be a datagridview combo box as well as a datagridview textbox .
the code is below

private void dgvForm_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            DataGridViewComboBoxEditingControl comboControl = e.Control as DataGridViewComboBoxEditingControl;
            if (comboControl != null)
            {
                //Set the DropDown style to get an editable ComboBox
                if (comboControl.DropDownStyle != ComboBoxStyle.DropDown)
                {
                    comboControl.DropDownStyle = ComboBoxStyle.DropDown;

                    int r = dgvForm.CurrentRow.Index;

                   
                }
            }
        }



and 

private void dgvFrom_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            DataGridViewComboBoxCell cell = dgvForm.CurrentCell as DataGridViewComboBoxCell;

            if (cell != null && !cell.Items.Contains(e.FormattedValue))
            {
                // Insert the new value into position 0
                // in the item collection of the cell
                cell.Items.Insert(0, e.FormattedValue);
                // When setting the Value of the cell, the  
                // string is not shown until it has been
                // comitted. The code below will make sure 
                // it is committed directly.
                if (dgvForm.IsCurrentCellDirty)
                {
                    // Ensure the inserted value will 
                    // be shown directly.
                    // First tell the DataGridView to commit 
                    // itself using the Commit context...
                    dgvForm.CommitEdit(DataGridViewDataErrorContexts.Commit);
                }
                // ...then set the Value that needs 
                // to be committed in order to be displayed directly.
                cell.Value = cell.Items[0];
            }
        }

but when i add this code all the combo box becomes datagridviewtextboxes when the datagridview combo box is being clicked..

the data gridview is already created and the columns are defined, with three datagridview combo box columns, i wna tone datagridview combo box column to be acing as a datagridview text box column when the cell is being clicked

[Mitja Bonca]

Try this:

this.dataGridView1["columnIndex", "rowIndex"] = new DataGridViewTextBoxCell();

[judithSampathwa]

Try this:

this.dataGridView1["columnIndex", "rowIndex"] = new DataGridViewTextBoxCell();

is it instead of the below line

DataGridViewComboBoxCell cell = dgvForm.CurrentCell as DataGridViewComboBoxCell;
