Well you can check the dataset ds1 if it is null.

C#

string sql = "select [DocEntry],[JobCardNo],[ITEMNAME],[OD] ,[PlanQty],[FinalInspectionRemarks] ,[OrderDate] ,[Division],[ChervonSet],[Profile] from SAPProduction.FactoryProductionData WHERE JobCardNo ='" + findjobsap.Text.ToString() + "'";
SqlDataAdapter da1 = new SqlDataAdapter(sql, objConn1);
DataSet ds1 = new DataSet();
objConn1.Open();
da1.Fill(ds1, "FactoryProductionData");

if (ds1 == null)
{  
    objConn1.Close();
    return;
}

dataGridView1.DataSource = ds1;
dataGridView1.DataMember = "FactoryProductionData";
objConn1.Close();

    return;
}
 
dataGridView1.DataSource = ds1;
dataGridView1.DataMember = "FactoryProductionData";
objConn1.Close();

C#

if (dataGridView1.Rows.Count <= 0)
            {
                MessageBox.Show("");
            }

Solution 4

Add a condition before you bind the grid with dataset as below:

C#

if (ds1.Tables[0].Rows.Count > 0)
{
   datagridview.DataSource = ds1;
   datagridview.DataBind();
}
else
{
    datagridview.Visible = false;
    //Show a label or message
    MessageBox.Show("Job Card not found");     
}
