To populate a column with data when the form loads, set a loop with the grid's indexer to the data to fill the column. Add the following code to the Form_Load event to set column one to zero:

To write code in Visual Basic

Dim r As Integer
For r = C1FlexGrid1.Rows.Fixed To C1FlexGrid1.Rows.Count - 1
    Me.C1FlexGrid1(r, 1) = 0
Next

To write code in C#

int r;
for (r = c1FlexGrid1.Rows.Fixed; r <= c1FlexGrid1.Rows.Count -1;r++)
{
    this.c1FlexGrid1[r, 1] = 0;
}

This topic illustrates the following:

Column one fills with zeros.
