Set the Default value for Combox present in DataGridview

Hi All,

I am using DataGridview and there is a Combobox column is present in the datagrid.

I am binding the DataGridViewComboboxcolumn with a DataSource.

DataGridViewComboBoxColumn cmbInstType = (DataGridViewComboBoxColumn)grdCashMemoDetails.Columns["grdCashMemoDetailsInstrumentType"];

DataTable instType = new DataTable(); "Value", typeof(int)); "Display", typeof(String)); "Cash"); "Card"); "DD"); "Cheque"); "Display"; "Value";

instType.Columns.Add(

instType.Rows.Add(1,

instType.Rows.Add(2,

instType.Rows.Add(3,

instType.Rows.Add(4,

cmbInstType.DisplayMember =

cmbInstType.ValueMember =

cmbInstType.DataSource = instType;

Now I want to set the default selected value for the combobox as

grdCashMemoDetails.Rows[e.RowIndex].Cells[(

int)enmGridViewColumnIndex.InstrumentType].Value = 2; But this is not working.

Please guide me how to do this.

Where are you doing this code the sets the value property? The typical place is the DataGridView.DefaultValuesNeeded event.

Note that when bound to a DataSet, you might also consider the alternative of setting the DataColumn's DefaultValue property which you can do in code or even through the Visual Studio strongly-typed DataSet designer.

Hi Gyanendar,

Could you please provide the error you met or why it does not work? You code is good, I cannot find which sentence is incorrect. This is a sample code:
