Asp.net 从codebehind禁用Radgrid中的编辑

我是telerik组件的新手。我有一个包含Radgrid的页面，我想从代码隐藏中禁用Radgrid中的编辑。我已经禁用了我认为会影响编辑的所有内容，但它仍然具有“行上编辑”双击功能。我怎样才能禁用它

假设您需要以编程方式禁用编辑/删除，则此代码段应完成以下工作：

protected void RadGrid1_PreRender(object sender, EventArgs e) 
{ 
if (yourCondition) 
  { 
    foreach( GridDataItem item in RadGrid1.MasterTableView.Items ) 
    { 
        LinkButton btnDelete = (LinkButton)item.FindControl("columnDelete"); 
        btnDelete.Enabled = false; 

        LinkButton btnEdit = (LinkButton)item.FindControl("columnEdit"); 
        btnEdit.Enabled = false; 
    } 
  } 
} 

protected void RadGrid1_PreRender(object sender, EventArgs e) 
{ 
if (yourCondition) 
  { 
    foreach( GridDataItem item in RadGrid1.MasterTableView.Items ) 
    { 
        LinkButton btnDelete = (LinkButton)item.FindControl("columnDelete"); 
        btnDelete.Enabled = false; 

        LinkButton btnEdit = (LinkButton)item.FindControl("columnEdit"); 
        btnEdit.Enabled = false; 
    } 
  } 
}
