I have a datagridview in one form which has a quantity field. it contains int type of numbers. I want to be able to create a combobox field in another datagridview in another form which will get a range depending on the quantity in the other form.

for example the quantity I input in the first form is 5.When I save it I want to show in the other form a combobox which has values that range from 1 to 5.

I am using C# and visual studio 2010

C#

this.itemqtyDataGridViewTextBoxColumn.DataSource = Enumerable.Range(0, quantityfromtheotherform).ToArray();

You could try setting different data source to the cell than for the grid.

like this:

C#

DataGridViewComboBoxColumn newColumn = new DataGridViewComboBoxColumn();
newColumn.Name = "abc";
newColumn.DataSource = new string[] { "a", "b", "c" };
dataGridView1.Columns.Add(newColumn);

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    DataGridViewComboBoxCell cell = (DataGridViewComboBoxCell)(row.Cells["abc"]);
    cell.DataSource = new string[] { "a", "c" };
}

Solution 1

C#

for (int i = 1; i <= num; i++)
            {
                comboBox1.Items.Add(i);
            }

So how do i get the data from the quantity column? if i have 2 rows with different quantities then the comboboxes in the other form would also depend on that.

example:

quantity combobox
5 1 to 5
10 1 to 10
