用于在数据网格视图上选中复选框的解决方案

>我在向数据网格视图插入复选框列时使用以下代码，

DataGridViewCheckBoxColumn checkBoxColumn = new DataGridViewCheckBoxColumn(); dataGridView1.Columns.Add(checkBoxColumn);

当我尝试选中复选框时，它不是选择ECD（未选中或未选中），有没有更好的方法可以做到这一点？

用于在数据网格视图上选中复选框的解决方案

您只是在网格视图中添加一列，但在分配数据源时，网格视图。将网格视图与数据源绑定以访问行以选中或取消选中复选框。

根据评论进行编辑。

可以使用 RowDataBound 事件在 bihnding 期间使用网格视图的行实例和数据源数据来启用/禁用复选框。

void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
       CheckBox chk = (CheckBox)e.Row.FindControl("chkBoxID");
       if(DataBinder.Eval(e.Row.DataItem, "datasourceColumnName").ToString() == "someval")
             chk.Enabled = false;
  }
}

您可以使用本文

rotected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //Check for the row type, which should be data row
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //Find the check boxes and assign the values from the data source
            ((CheckBox)e.Row.FindControl("chkSelect")).Checked = Convert.ToBoolean(((DataRowView)e.Row.DataItem)[1]);
            ((CheckBox)e.Row.FindControl("chkAdd")).Checked = Convert.ToBoolean(((DataRowView)e.Row.DataItem)[2]);
            ((CheckBox)e.Row.FindControl("chkEdit")).Checked = Convert.ToBoolean(((DataRowView)e.Row.DataItem)[3]);
            ((CheckBox)e.Row.FindControl("chkAll")).Checked = Convert.ToBoolean(((DataRowView)e.Row.DataItem)[4]);
            //Find the checkboxes and assign the javascript function which should
            //be called when the user clicks the checkboxes.
            ((CheckBox)e.Row.FindControl("chkSelect")).Attributes.Add("onclick", "checkBoxClicked('" +
((CheckBox)e.Row.FindControl("chkSelect")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAdd")).ClientID
+ "','" + ((CheckBox)e.Row.FindControl("chkEdit")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAll")).ClientID + "'," + "'SELECT')");
            ((CheckBox)e.Row.FindControl("chkAdd")).Attributes.Add("onclick", "checkBoxClicked('" +
((CheckBox)e.Row.FindControl("chkSelect")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAdd")).ClientID
+ "','" + ((CheckBox)e.Row.FindControl("chkEdit")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAll")).ClientID + "'," + "'ADD')");
            ((CheckBox)e.Row.FindControl("chkEdit")).Attributes.Add("onclick", "checkBoxClicked('" +
((CheckBox)e.Row.FindControl("chkSelect")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAdd")).ClientID
+ "','" + ((CheckBox)e.Row.FindControl("chkEdit")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAll")).ClientID + "'," + "'EDIT')");
            ((CheckBox)e.Row.FindControl("chkAll")).Attributes.Add("onclick", "checkBoxClicked('" +
((CheckBox)e.Row.FindControl("chkSelect")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAdd")).ClientID
+ "','" + ((CheckBox)e.Row.FindControl("chkEdit")).ClientID + "','" + ((CheckBox)e.Row.FindControl("chkAll")).ClientID + "'," + "'ALL')");
        }
    }
