在datagridview winform中隐藏默认的灰色列

Question

Is there any way to remove or hide winform's datagrid gray area when data is not avaiable?

Second this how to remove/hide the default gray column?

  dataGridView1.DataSource = oresult;
  dataGridView1.Columns["Id"].Visible  = false;
  dataGridView1.Columns["AddedBy"].Visible = false;
  dataGridView1.Columns["AddmissionInClass"].Visible = false;
  dataGridView1.Columns["IsDeleted"].Visible = false;
  dataGridView1.Enabled = false;

I'm hiding useless columns like this but unable to find way to hide these.

Answer 1

要隐藏第一列，您可以将数据网格的RowHeadersVisible设置为 false

Answer 2

Just set the Background-Color and the RowHeadersVisible-State of your DataGridView:

dataGridView1.BackgroundColor = Color.White;
dataGridView1.RowHeadersVisible = false;

Answer 3

您需要将 RowHeaderVisible 的属性（来自 gridview 属性）设置为 false

Answer 4

Just put this piece of code. Worked for me.

DataGrid.RowHeadersVisible = false;
DataGrid.ColumnHeadersVisible = false;

Answer 5

You have two approaches to do this:

1. Adding this line:

    dataGridView1.RowHeadersVisible = false;

   to...

    private void Form1_Load(object sender, EventArgs e) { dataGridView1.RowHeadersVisible = false; }

   -OR-

2. From (Project's Properties) window change True to false like this:

Answer 6

If you are trying to delete grid view column in column level and its not being reflected in grid view please follow as below: We can't delete the column of grid view in column level. So, delete the column's cell in row level (means in each and every row).

foreach (GridViewRow Row in this.searchResults.SearchResultGrid.Rows)
                    {
                        if (Row.RowType == DataControlRowType.DataRow)
                        {
                            Row.Cells[0].Visible = false;
                        }
                    }
                    GridViewRow HeaderRow = this.searchResults.SearchResultGrid.HeaderRow;
                    HeaderRow.Cells[0].Visible = false;

Answer 7

DGV.RowHeadersDefaultCellStyle.Padding = New Padding(3)

Answer 8

Although a few years have passed but I have reached it now... I had to change it in all the DataGrids in all the project. I make this in aApp.XAML

  <Style TargetType="DataGrid">
 <Setter Property="RowHeaderWidth" Value="0"/>
   </Style>
