# Insert, Update, Delete in DataGridView
[DataGridView](https://www.mindstick.com/articles/63/how-to-add-button-in-datagridview-in-csharp-dot-net) is a control which is widely used in developing window application. DataGridView is an [efficient](https://www.mindstick.com/articles/33637/three-tips-for-an-energy-efficient-home-for-2019) way through which we can display [database table](https://www.mindstick.com/forum/159366/how-to-test-regular-expressions-in-sql-without-using-database-table) data into customizable format that is where we can edit information, delete information, insert information or update information indirectly from original database and after the user confirmation these changes reflects into the original database. DataGridView control helps to [display data](https://www.mindstick.com/forum/34030/how-to-display-data-in-the-table-using-angular-js) into customizable grid. DataGridView control provides the flexibility to show data, modify data and much more with flexible tabular format.
Here I am using a datagridview control with different [functionality](https://www.mindstick.com/blog/136/using-watermark-functionality-in-textbox-by-jquery) such as update, delete, insert and much more. Let’s see a brief description of example.
Step 1: First open [visual studio](https://www.mindstick.com/articles/12378/visual-studio-for-mac-is-out-of-beta-preview-now-officially-available) and click on file menu and select new [project](https://yourviews.mindstick.com/story/1788/things-to-ensure-your-construction-project-is-successful) and then click project for window application.
Step 2: After Successful creating a new project then drag datagridview control from toolbox and drop it into [window form](https://www.mindstick.com/forum/527/how-to-pass-datagridview-s-cells-value-to-another-window-form) where you want to use it.
Here I making window form with design which are appears as;
After successful design of window form write the following code to perform the action according to buttons.
```
public partial class Welcome : Form { /// /// declare the varraible to use in different mode /// boolcheck=false; SqlDataAdapter da; SqlConnection con; DataTable dt; intindex ; stringtxt_Name; stringtxt_Address; stringtxt_Designation; stringtxt_Department; publicWelcome() { InitializeComponent(); /// validation error message visibility false label2.Visible= false; /// bind table data with data grid view DataBind(); /// disable the update button at form loading time btn_Update.Enabled= false; } /// /// Data bind method use to bind table data with datagrid view /// public voidDataBind() { /// bind database table data with datagrid view con=newSqlConnection(ConnectionString.connString()); con.Open(); da=newSqlDataAdapter(); da.SelectCommand= newSqlCommand("Select * from tblGridView",con); /// create sqlcommandbuilder to update, delete etc. in data grid view SqlCommandBuilder cmdbuilder= new SqlCommandBuilder(da); // data table to hold table data dt=newDataTable(); da.Fill(dt); dataGridView1.DataSource=dt; /// define all column of datagrid view readonly ReadOnlyGrid(); } /// /// readonlygrid method use to declare all cell of datagridview is read only /// public voidReadOnlyGrid() { // define all cell datagrid view readonly for (inti=0;

} // check if validation message are showing else if (label2.Text!= "") { MessageBox.Show("Userid must be integer value"); } else { // insert new record and bind with database table /// aoss the parameter in stored procedure gridviewtest SqlCommand cmd= new SqlCommand("GridviewTest", con); cmd.CommandType=CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@Userid", textBox1.Text); cmd.Parameters.AddWithValue("@Name", textBox2.Text); cmd.Parameters.AddWithValue("@Address", textBox3.Text); cmd.Parameters.AddWithValue("@Designation", textBox4.Text); cmd.Parameters.AddWithValue("@Department", textBox5.Text); cmd.ExecuteNonQuery(); MessageBox.Show("Data Successfully inserted"); // bind table data with gridview DataBind(); // make empty text field EmptyField(); } } catch (Exception ae) { MessageBox.Show(ae.ToString().Substring(0,148)); } } /// /// this method help to update data of existing information /// private void btn_Update_Click(objectsender, EventArgse) { try { /// update existing information /// check if any textfield is empty if ((textBox2.Text== ""||textBox3.Text==""||textBox4.Text ==""||textBox5.Text=="")) { MessageBox.Show("Fill all enteries"); } /// if no modification has been changed else if (txt_Name== textBox2.Text&&txt_Address==textBox3.Text &&txt_Designation==textBox4.Text&& txt_Department==textBox5.Text) { } else { /// update information by calling gridviewupdate stored procedure SqlCommand cmd= new SqlCommand("GridviewUpdate", con); cmd.CommandType=CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@Userid", textBox1.Text); cmd.Parameters.AddWithValue("@Name", textBox2.Text); cmd.Parameters.AddWithValue("@Address", textBox3.Text); cmd.Parameters.AddWithValue("@Designation", textBox4.Text); cmd.Parameters.AddWithValue("@Department", textBox5.Text); cmd.ExecuteNonQuery(); MessageBox.Show("Data Successfully updated"); DataBind(); EmptyField(); } } catch (Exception ae) { MessageBox.Show(ae.ToString()); } } /// /// this method fill all the existing data when double click on datagridview row header to update data /// private void dataGridView1_RowHeaderMouseDoubleClick(objectsender, DataGridViewCellMouseEventArgse) { /// update existing information by double click on rowheader of datagridview btn_Update.Enabled= true;

textBox3.Text=dataGridView1.Rows[e.RowIndex].Cells[2].Value.ToString(); txt_Address=textBox3.Text; textBox4.Text=dataGridView1.Rows[e.RowIndex].Cells[3].Value.ToString(); txt_Designation=textBox4.Text; textBox5.Text=dataGridView1.Rows[e.RowIndex].Cells[4].Value.ToString(); txt_Department=textBox5.Text; textBox1.Enabled= false; } /// /// cancel button method to disable or enable button /// private voidbtn_Edit_Click(objectsender, EventArgse) { /// event when clicked on cancel button btn_Update.Enabled= false;

string caption= "Delete Records"; MessageBoxButtonsbutton=MessageBoxButtons.OKCancel; if (MessageBox.Show(messageText, caption, button) == DialogResult.OK) { foreach (DataGridViewRow dr indataGridView1.SelectedRows) { int val= Convert.ToInt32(dr.Cells["Userid"].Value.ToString()); SqlCommand cmd= new SqlCommand("GridViewDelete", con); cmd.CommandType=CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@userid", val); cmd.ExecuteNonQuery(); } DataBind(); } } else { /// if one row select for delete if (index>0) { string messageText= "Do you want to permanent delete data"; string caption= "Delete Records"; MessageBoxButtonsbutton=MessageBoxButtons.OKCancel; /// check confirmation of user to delete data from table if (MessageBox.Show(messageText, caption, button) == DialogResult.OK) { SqlCommand cmd= new SqlCommand("GridViewDelete", con); cmd.CommandType=CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@userid", index); cmd.ExecuteNonQuery(); DataBind(); index=0; } } else if(dataGridView1.Rows.Count <=0) { // grid view have no record MessageBox.Show("No data found to delete "); } else { MessageBox.Show("Select row to delete data"); } } } /// /// this method fire when singleclick on datagridview row header, it is used for delete single row /// private void dataGridView1_RowHeaderMouseClick(objectsender, DataGridViewCellMouseEventArgse) { /// row select for delete data form data table index=Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells["Userid"].Value.ToString()); } private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgse) { // set index value in every cell click event index=0; } }
```
After Write the above codes debugs the program and perform the action.
Now insert the information
When you click on insert button then a confirmation message box open and when you click on ok button then new record will be shown into datagridview.
Now in the same manner you can perform all action like update, delete etc.
