This is my code:

       {
           try
           {
               if (txtVehClass.Text.Trim() == string.Empty)

                   return;

                   string strQry = string.Empty;
                   strQry = "Select * from VehClass where upper(code)='" + txtVehClass.Text.Trim().ToUpper() + "' and isnull(intstatus,0)=0";

                   DataSet dsGrid = SqlHelper.ExecuteDataset(ConfigurationSettings.AppSettings["TrafficDB"], CommandType.Text, strQry);

                   if (dsGrid != null && dsGrid.Tables.Count > 0 && dsGrid.Tables[0].Rows.Count > 0)

                       txtVehClass.Tag = dsGrid.Tables[0].Rows[0]["Intcode"].ToString();
                       txtVehClass.Text = dsGrid.Tables[0].Rows[0]["code"].ToString();
                       txtVehClassName.Text = dsGrid.Tables[0].Rows[0]["NameArb"].ToString();
                   }

Include a catch block right after try block, please.

Should be like this:

C#

private void txtCountryCode_Enter(object sender, EventArgs e)
{
    try
    {
        //whatever
    }
    catch (Exception exception)
    {
        //if an error occurs with in the try block, it will handled here.
    }
}

I would suggest you to buy a basic programming book and read the concepts.
Read more documentation here at MSDN:

C#

        {
            try

                    DataSet dsGrid = SqlHelper.ExecuteDataset(ConfigurationSettings.AppSettings["TrafficDB"], CommandType.Text, strQry);
 
                    if (dsGrid != null && dsGrid.Tables.Count > 0 && dsGrid.Tables[0].Rows.Count > 0)
                    
                        txtVehClass.Tag = dsGrid.Tables[0].Rows[0]["Intcode"].ToString();
                        txtVehClass.Text = dsGrid.Tables[0].Rows[0]["code"].ToString();

                }
 
            }
            catch(Exception ex)
            {// do exception handling here
            }
            finally
            {// do resource cleanup here, optional in your case
            }
    }

Add a catch or finally block:

C#

private void txtCountryCode_Enter(object sender, EventArgs e)
    {
    try
        {
        if (txtVehClass.Text.Trim() == string.Empty)

            return;

        string strQry = string.Empty;
        strQry = "Select * from VehClass where upper(code)='" + txtVehClass.Text.Trim().ToUpper() + "' and isnull(intstatus,0)=0";

        //DataSet dsGrid = SqlHelper.ExecuteDataset(ConfigurationSettings.AppSettings["TrafficDB"], CommandType.Text, strQry);

        if (dsGrid != null && dsGrid.Tables.Count > 0 && dsGrid.Tables[0].Rows.Count > 0)
            {
            txtVehClass.Tag = dsGrid.Tables[0].Rows[0]["Intcode"].ToString();
            txtVehClass.Text = dsGrid.Tables[0].Rows[0]["code"].ToString();
            txtVehClassName.Text = dsGrid.Tables[0].Rows[0]["NameArb"].ToString();
            }
        }
    catch (Exception ex)
        {
        // Report, log or otherwise handle the exception
        Console.WriteLine(ex.Message);
        }

    }

Do note that you are also missing an open curly bracket after the if statement - indentation will not make it execute all three statements without it! (I added it here so you can see what I mean)
