delete record from gridview but not from database - asp.net

Question

I am trying to delete record from grid but not from Database.
I want to set database field ISDeleted 1 when data deleted from gridview but don't want to delete record from db.
My code delete records from both gridview and db.
Where to change in my code-
string strcon = ConfigurationManager.ConnectionStrings["Dbconnection"].ConnectionString;
SqlCommand command;
protected void Page_Load(object sender, EventArgs e)
{
tblAdd.Visible = false;
Label1.Visible = false;
//GridView1.DataBind();
if (!Page.IsPostBack)
{
fillLanguageGrid();
}
}
public void fillLanguageGrid()
{
GridView1.DataSourceID = "SqlDataSource1";
GridView1.DataBind();
}
protected void btnDelete_Click(object sender, EventArgs e)
{
foreach (GridViewRow gvrow in GridView1.Rows)
{
CheckBox chkdelete = (CheckBox)gvrow.FindControl("chk");
if (chkdelete.Checked)
{
string name= Convert.ToString(GridView1.DataKeys[gvrow.RowIndex].Values["Name"].ToString());
// command.Parameters.Add(new SqlParameter("#status", SqlDbType.VarChar, 50));
deleteRecordByName(name);
}
}
fillLanguageGrid();
}
public void deleteRecordByName(string Name)
{
SqlConnection sqlConnection = new SqlConnection(strcon);
using (SqlCommand command = new SqlCommand("[dbo].[hrm_Langauges]", sqlConnection))
{
// define this to be a stored procedure
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add(new SqlParameter("#status", SqlDbType.VarChar, 50));
// define the parameter and set its value
command.Parameters.Add(new SqlParameter("#Name", SqlDbType.VarChar)).Value = Name;
command.Parameters.Add(new SqlParameter("#IsDeleted", SqlDbType.Bit)).Value = 1;
command.Parameters["#status"].Value = "Delete";
//open connection, execute DELETE query, close connection
sqlConnection.Open();
command.ExecuteNonQuery();
sqlConnection.Dispose();
}
}

For that you need to add a column in your respective database table whether to show that record or not.For Ex: add column like Visible int.
Assume if
Visible =1 --> Show that record in gridview
Visible =0 --> Hide that record in gridview
By default make Visible =1 so all records are shown in gridview(write the query like Select ......Where Visible =1).when you try to delete record use update query that need to update Visible column 1 to 0.So your gridview only shows records where visible =1 .That particular deleted record is not shown in your gridview because its Visible column is 0.Try this..
