隐藏datagridview中的id列，但需要使用它

Question

I want to hide id column from datagridview. I tried by changing stored procedure / SQL query, it works but I was unable to get id of that entry for some reason I also need id of each entry but don't want to show on front end.

Any suggestions, please?

private void category_Load(object sender, EventArgs e)
{
    // TODO: This line of code loads data into the 'shopBillingDataSet.category' table. You can move, or remove it, as needed.
    this.categoryTableAdapter.Fill(this.shopBillingDataSet.category);
    button3.Enabled = false;
    button1.Enabled = true;
}

private void button1_Click(object sender, EventArgs e)
{
    BSL.category obj = new BSL.category();
    obj.catName = textBox1.Text;
    obj.catDesc = textBox2.Text;

    DAL.categoryDAL obj1 = new categoryDAL();
    obj1.addCategory(obj);
    this.categoryTableAdapter.Fill(this.shopBillingDataSet.category);
    textBox1.Text = "";
    textBox2.Text = "";
    MessageBox.Show("New Category entered");
    category_Load(sender,e);
}

Answer 1

As comment says, you can do this:

dgName.Columns[i].Visible = false;

Or if you are binding to a class, you can set a custom attribute on the data value, something like this:

public class Row {
   [Browsable(false)]
   public int Id {get;set;}
   public string Name {get;set;}
}
//dgName.DataSource = new BindingList<Row>();

*edit: obviously you wouldn't want to bind to an empty list...but however you populate your list, this just shows how the Browsable attribute could be used.

Answer 2

First bind the grid and then try this code.

GridViewId.Columns[index].Visible = false;//Put index number to hide the Columns like 0,1 etc..
