Question

Hi

I have a datagridview in that i have a comboboxColumn

Now i want to set the default value for that so that each newly added row have that default value of the combobox

there is no for User  to select the value Only the user has to do is  change the value accordingly

Means if the ComboBox values are DR. & Cr.

Then Dr. is default value for that combo in the datagridview column

 

Thanks a lot in advance

Answer 2

It can be done without a line of code in the DataSet Designer. Just set a default value for the column that is a source of data for your combobox.

Answer 3

You may set as follow;

DataGridViewComboBoxColumn salColumn = new DataGridViewComboBoxColumn();

salColumn.DefaultCellStyle.NullValue = ((GOR)gor.Items[0]).GorName;

Wher GOR object is as follow:

public class GOR

{

private String gorName;

private String gorValue;

 

public GOR(String gorName, String gorValue)

{

this.gorName = gorName;

this.gorValue = gorValue;

}

public String GorName

{

get { return gorName; }

set { this.gorName = value; }

}

public String GorValue

{

get { return gorValue; }

set { this.gorValue = value; }

}

}

Just handling the cellFormatting event:

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)

 {

      if (e.ColumnIndex == 0) // your combo column index

      {

          e.Value = "Dr.";

      }

 }

Answer 6

 

Dim dgvCell1 As System.Windows.Forms.DataGridViewComboBoxCell

 

Dim dgvCell2 As System.Windows.Forms.DataGridViewComboBoxCell

'Here my Column1 and Column2 are DataGridViewComboBox

'myDataGridViewControlName - is the Name for my DataGridViewControl

dgvCell1 =

CType(myDataGridViewControlName.Rows(0).Cells(1), Windows.Forms.DataGridViewComboBoxCell)

dgvCell2 =

CType(myDataGridViewControlName.Rows(0).Cells(2), Windows.Forms.DataGridViewComboBoxCell)

 

'dgvCell1.Selected = True

 

If Not dgvCell1.Items.Count = 0 Then

dgvCell1.Value = dgvCell1.Items(0)

 

End If

 

If Not dgvCell2.Items.Count = 0 Then

dgvCell2.Value = dgvCell2.Items(0)

 

End If

Hope this works....

Answer 7

private void dgvVisita_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            if (e.ColumnIndex == 5)
            {
                e.Value = "0";
            }
        }

I used this but everytime I select a number from the ComboBox, It returns to "0".
