if (dsm.Tables[3].Rows.Count > 0)
{
int i = 0;
DataTable sco = dsm.Tables[3];
foreach (DataRow row in sco.Rows)
{
//lblMessage.Text = dsm.Tables[3].Rows[i]["Cust_Name"].ToString();
//lblMessage.Text= (Convert.ToInt32(dsm.Tables[3].Rows[i]["Credit_Check"]).ToString());
if (dsm.Tables[3].Rows[i]["Cust_Name"] != DBNull.Value && Convert.ToInt32(dsm.Tables[3].Rows[i]["Credit_Check"]) != 0)
{
divARIssue.Visible = true;
lblMessage.Visible = true;
btnReport.Enabled = false;
gvARIssue.DataSource = dsm.Tables[3];
gvARIssue.DataBind();
DateTime e_date = Convert.ToDateTime(dsm.Tables[3].Rows[16]["BaseLine_Date"].ToString());
lblMessage.Text = String.Format("{0:dd MMM yyyy}", e_date);

}
else if (dsm.Tables[3].Rows[i]["Cust_Name"] == DBNull.Value || Convert.ToInt32(dsm.Tables[3].Rows[i]["Credit_Check"]) != 0)
{
string abc = dsm.Tables[3].Rows[i]["Cust_Code"].ToString();
lblMessage.Text = "Customer not present in master for existing Customer code"+(abc);
divARIssue.Visible = true;
lblMessage.Visible = true;
btnReport.Enabled = false;
gvARIssue.DataSource = null;
gvARIssue.DataBind();
//break;

}
else if(dsm.Tables[3].Rows[i]["Cust_Name"] != DBNull.Value || Convert.ToInt32(dsm.Tables[3].Rows[i]["Credit_Check"]) == 0)
{
string abc = dsm.Tables[3].Rows[i]["Cust_Code"].ToString();
lblMessage.Text = "No Credit term for Exsiting Customer in master"+ (abc);

Here is another solution

C#

for (int i = 0; i < table.Rows.Count; i++)
            {

                if (table.Rows[i]["Employee"] == DBNull.Value)
                {
                    string s = string.Empty;
                }



            }

If you can fetch data into Data Table then next part is to check null you can go the block i have attached. For each cell you need to check above.
