c＃backgroundworker创建datagridview和创建列

Question

I am getting this error "No row can be added to a DataGridView control that does not have columns. Columns must be added first." what am i doing wrong here?

        //create datagridview1
          DataGridView dataGridView1 = new DataGridView();

         // DataGridViewColumn column = new DataGridViewTextBoxColumn();

          // Initialize the DataGridView.
          dataGridView1.AutoGenerateColumns = false;
          dataGridView1.AutoSize = true;

          DataGridViewColumn column1 = new DataGridViewTextBoxColumn();
          column1.DataPropertyName = "Column1";
          column1.Name = "title";
          dataGridView1.Columns.Add(column1);

          DataGridViewColumn column2 = new DataGridViewTextBoxColumn();
          column2.DataPropertyName = "Column2";
          column2.Name = "imageurl";
          dataGridView1.Columns.Add(column2);

          DataGridViewColumn column3 = new DataGridViewTextBoxColumn();
          column3.DataPropertyName = "Column3";
          column3.Name = "videourl";
          dataGridView1.Columns.Add(column3);

          DataGridViewColumn column4 = new DataGridViewTextBoxColumn();
          column4.DataPropertyName = "Column4";
          column4.Name = "done";
          dataGridView1.Columns.Add(column4);

Answer 1

try

dataGridView1.Columns.Add("Column","Test");

or if you want to choose coulmn type

DataGridViewColumn  newCol = new DataGridViewColumn(); // add a column to the grid
DataGridViewCell cell = new DataGridViewCell(); //Specify which type of cell in this column
newCol.CellTemplate = cell;

newCol.HeaderText = "test2";
newCol.Name = "test2";
newCol.Visible = true;
newCol.Width = 40;

gridColors.Columns.Add(newCol);
