Question

Hi Programmers,
Actually I have a DataGridViewComboBoxCell in DataGridvIew and I need to change the DataGridViewComboBox value if the condition is true when the CellContentClick event is fired.
My Code Goes Like this:

    private void gridviewholiday_CellContentClick_1(object sender, DataGridViewCellEventArgs e)
    {
        int row = e.RowIndex;
        int colo = e.ColumnIndex;


        /*=============== To Show The Details  =====================*/

        if (e.ColumnIndex == 4)
        {
            if (Convert.ToBoolean(gridviewholiday.Rows[e.RowIndex].Cells[0].Value))
            {
                if (Type == "CUS")
                {
                    Type = test.colType;
                    if (Type == "NO")
                    {


                        ComboBox combo = (ComboBox)sender;
                        combo.SelectedIndex = 0;

                    }
                }
    }

But it gives error while casting DataGridView to Combobox.

Please help me out.

Hello Friends!

I got my answer and i manually select the DataGridviewComboBoxCell.

private void gridviewholiday_CellContentClick_1(object sender, DataGridViewCellEventArgs e)
{
    int row = e.RowIndex;
    int colo = e.ColumnIndex;


    /*=============== To Show The Details  =====================*/

    if (e.ColumnIndex == 4)
    {
        if (Convert.ToBoolean(gridviewholiday.Rows[e.RowIndex].Cells[0].Value))
        {
            if (Type == "CUS")
            {
                Type = test.colType;
                if (Type == "NO")
                {
                     /*===== set the selected value of comboboxCellItems   ==========*/

                      gridviewholiday.Rows[e.RowIndex].Cells["colType"].Value="ALL"



                }
            }
}

And finally my problem is solved.
