将行添加到网格视图

5 回答

• 12

  DataTable dt = new DataTable();
  DataRow dr = dt.NewRow();
  dr["Column1"] = string.Empty;
  dt.Rows.Add(dr);
  

  然后，您可以将 GridView 绑定到 DataTable ...

  gv.DataSource = dt;
  gv.DataBind();

  dataGridView1.Columns[0].Name = "column1";
  dataGridView1.Columns[1].Name = "column2";
  
  string[] row1 = new string[] { "column1 value", "column2 value" };
  dataGridView1.Rows.Add(row1);

  GridViewRowsCollection没有 .Add 方法，因此您无法直接对GridView执行此操作 .

  还有其他选择 . 例如，如果将其绑定到DataTable - 您可以将包含数据的自定义行添加到DataTable .

  另一种选择 - 通过在呈现的HTML表中添加一行来在客户端上执行此操作 .

  行可以插入 GridView_RowCreated ，Like

  protected void gvItems_RowCreated(object sender, GridViewRowEventArgs e)
  {                    
      GridViewRow NewHeader = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);
      NewHeader.Font.Bold = true;
      NewHeader.CssClass = "heading";
  
      //Item#
      TableCell NewHeaderCell = new TableCell();
      NewHeaderCell.Text = "#";
      NewHeaderCell.HorizontalAlign = HorizontalAlign.Left;
      NewHeader.Cells.Add(NewHeaderCell);
  
      //Item#
      NewHeaderCell = new TableCell();
      NewHeaderCell.Text = "Item#";
      NewHeaderCell.HorizontalAlign = HorizontalAlign.Left;
      NewHeader.Cells.Add(NewHeaderCell);
  
      //Amount
      NewHeaderCell = new TableCell();
      NewHeaderCell.Text = "Amount";
      NewHeaderCell.HorizontalAlign = HorizontalAlign.Right;
      NewHeader.Cells.Add(NewHeaderCell);
      GridView1.Controls[0].Controls.AddAt(e.Row.RowIndex + 
          rowIndex, NewHeader);
  }

  我仍然建议您使用绑定/数据源，但当然您不必这样做 . 以下应该做你想要的：

  DataGridViewTextBoxColumn columntype = new DataGridViewTextBoxColumn();
          columntype.HeaderText = "Type";
          columntype.Width = 80;
          dataGridView1.Columns.Add(columntype);
