[Devaraj1987]

Hi,
I have a datagrid in which i have a datagridcombo box(editable),I have populated the combobox manualy by using the following code.

DataGridViewCom boBoxColumn Actioncolumn = new DataGridViewCom boBoxColumn();
Actioncolumn.Da taPropertyName = "ZSL_Action ";
Actioncolumn.He aderText = "Action";
string[] installs = new string[] { "red", "white", "green" };
Actioncolumn.It ems.AddRange(in stalls);
//Actioncolumn.It ems.Add("red");
//Actioncolumn.It ems.Add("white" );
//Actioncolumn.It ems.Add("green" );
Actioncolumn.Re adOnly = false;
dataGridView1.C olumns.Add(Acti oncolumn);

Now went i try to change the combo box value , DataError occurs. What shall i do.

Also by default only 1st value(i.e., Red) is assigned to the combo box. what shall i do.

DataGridViewComboBoxColumn Actioncolumn = new DataGridViewComboBoxColumn();
Actioncolumn.DataPropertyName = "ZSL_Action";
Actioncolumn.HeaderText = "Action";
string[] installs = new string[] { "red", "white", "green" };
Actioncolumn.Items.AddRange(installs);
//Actioncolumn.Items.Add("red");
//Actioncolumn.Items.Add("white");
//Actioncolumn.Items.Add("green");
Actioncolumn.ReadOnly = false;
dataGridView1.Columns.Add(Actioncolumn);

dataGridView1.Rows[dataGridView1.Rows.Add()].Cells[Actioncolumn.Index].Value = "white";
dataGridView1.Rows[dataGridView1.Rows.Add()].Cells[Actioncolumn.Index].Value = "green";
dataGridView1.Rows[dataGridView1.Rows.Add()].Cells[Actioncolumn.Index].Value = "red";
