How to change value of a column in DataGridView?

Question

Hiii,

In a C# WinApp, I have a form with a DataGridView and a ComboBox. the DataGridView contains columns i.e. No; Perticular, Quantity, Rate, Amount and Days. the ComboBox contains number 1 to 365.

Now, I am trying to change the 6th column (Days) using the ComboBox numbers. I want to do it as if I select '10' from the ComboBox all the cells in the Days column get that value. In short, I want to change the entire column value with the value selected from the ComboBox regardless, how many rows are there in the gridview.

 

Anybody please help.

 

Thank You.

        Mail.From = ma;
        Mail.To.Add(txtTo.Text);

        if(txtCC.Text.Trim().Length != 0)
            Mail.CC.Add(txtCC.Text);
        
        if(txtBCC.Text.Trim().Length != 0)
            Mail.Bcc.Add(txtBCC.Text);

        if (txtAttachment.Text.Trim().Length != 0)
        {
            string sAttach = txtAttachment.Text.Replace("\\","\\\\");
            Mail.Attachments.Add(new Attachment(sAttach));
        }
    

        //Note: When you make "IsBodyHtml" to true make 
    //ValidateRequest="false" in page derective
    //As to make HTML content passed.
        Mail.IsBodyHtml = true;        
        Mail.Body = txtComment.Text;


        //Setting Reply address.
        if (txtReplyTo.Text.Trim().Length != 0)
        {
            Mail.Headers.Add("Reply-To", txtReplyTo.Text);
        }
        else
        {
            Mail.Headers.Add("Reply-To", txtFrom.Text);
        }

        
        try
        {
            SmtpClient smtpMailObj = new SmtpClient();
        //eg:localhost, 192.168.0.x, replace with your server name
            smtpMailObj.Host = "myMailServer"; 
            smtpMailObj.Send(Mail);
            Response.Write("Your Message has been sent successfully");
        }
        catch (Exception ex)
