How to Navigate Records Based on DataGridView Using C#

This time, let’s learn how to navigate records based on datagridview using C#. This tutorial will show to you that you can put limitation on your displayed records in the datagridview. Sometimes, it’s stressful to scroll down if you are looking for a record that contains a lot of data. Well, this tutorial is a big help for you because you don’t have to scroll down anymore. You can now easily find the record that you’re looking for in just a click. Simply click the next and previous button to see other displayed records.

Creating Database

Create a database named "dbsubjects". Create a table in the database that you have created.
  1. CREATE TABLE `subject` (
  2. `SUBJ_ID` int(11) NOT NULL,
  3. `SUBJ_CODE` varchar(30) NOT NULL,
  4. `SUBJ_DESCRIPTION` varchar(255) NOT NULL,
  5. `UNIT` int(2) NOT NULL,
  6. `PRE_REQUISITE` varchar(30) NOT NULL DEFAULT 'None'
Add the data in the table.
  1. INSERT INTO `subject` (`SUBJ_ID`, `SUBJ_CODE`, `SUBJ_DESCRIPTION`, `UNIT`, `PRE_REQUISITE`) VALUES

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application in c#. navigate_createform

Step 2

Do the form just like shown below. navigate_setorm

Step 3

Go to the code editor. After that, add a namespace to access MySQL libraries.
  1. using MySql.Data.MySqlClient;

Step 4

Create a connection between C# and MySQL Database. After that, declare all the classes and variables that are needed.
  1. MySqlConnection con = new MySqlConnection("server=localhost;user id=root;password=;database=dbsubjects;sslMode=none");
  2. MySqlCommand cmd;
  3. MySqlDataAdapter da;
  4. DataTable dt;
  5. String sql;
  6. int maxrow;
  7. int inc_value;
  8. int resultPerPage = 10;
  9. int startResult;

Step 5

Create a method to retrieve a single result in the MySQL database.
  1. private void loadDataSingle(String sql)
  2. {
  3. try
  4. {
  5. con.Open();
  6. cmd = new MySqlCommand();
  7. cmd.Connection = con;
  8. cmd.CommandText = sql;
  9. da = new MySqlDataAdapter();
  10. da.SelectCommand = cmd;
  11. dt = new DataTable();
  12. da.Fill(dt);
  13. maxrow = dt.Rows.Count - 1;
  14. }
  15. catch (Exception ex)
  16. {
  17. MessageBox.Show(ex.Message);
  18. }
  19. finally
  20. {
  21. con.Close();
  22. da.Dispose();
  23. }
  24.  
  25. }

Step 6

Create a method to retrieve the list of data in the MySQL database.
  1. private void loadDataList(String sql,DataGridView dtg)
  2. {
  3. try
  4. {
  5. con.Open();
  6. cmd = new MySqlCommand();
  7. cmd.Connection = con;
  8. cmd.CommandText = sql;
  9. da = new MySqlDataAdapter();
  10. da.SelectCommand = cmd;
  11. dt = new DataTable();
  12. da.Fill(dt);
  13.  
  14. dtg.DataSource = dt;
  15. }catch(Exception ex)
  16. {
  17. MessageBox.Show(ex.Message);
  18. }
  19. finally
  20. {
  21. con.Close();
  22. da.Dispose();
  23. }
  24.  
  25. }

Step 7

Create a method for the previous function.
  1. private void goto_Previous()
  2. {
  3. if (inc_value == 0)
  4. {
  5. return;
  6. }
  7. else if(inc_value > 0)
  8. {
  9. inc_value = inc_value - 1;
  10. startResult = inc_value * resultPerPage;
  11. }
  12.  
  13. sql = "Select * from subject limit " + startResult + "," + resultPerPage + "";
  14. loadDataList(sql, dtg_list);
  15.  
  16. }

Step 8

Create a method for the next function.
  1. private void goto_Next()
  2. {
  3.  
  4. if (inc_value != maxrow - 2)
  5. {
  6. inc_value = inc_value + 1;
  7. startResult = inc_value * resultPerPage;
  8. }
  9. else
  10. {
  11. if (inc_value == maxrow)
  12. {
  13. return;
  14. }
  15. }
  16. sql = "Select * from subject limit " + startResult + "," + resultPerPage + "";
  17. loadDataList(sql, dtg_list);
  18.  
  19. }

Step 9

Double click the form and do the following codes for getting the total number rows of the table and limit the data to be displayed in the datagridview.
  1. sql = "Select * from subject";
  2. loadDataSingle(sql);
  3.  
  4. sql = "Select * from subject limit 10";
  5. loadDataList(sql, dtg_list);

Step 10

Double click the “Previous” button and call the method for the previous.
  1. goto_Previous();

Step 11

Double click the “Next” button and call the method for the next.
  1.  
  2. goto_Next();
