Spread 中默认点击左上角的表角(Corner)会选中Spread的全部单元格,有时候我们不希望这种选中行为,需要屏蔽该操作,此时我们可以使用下面的代码来进行屏蔽:

第一步:
重写页面的 Render 方法,并为 Corner 添加一个 onmousedown 的客户端事件

  • C#
 
  • protected override void Render(HtmlTextWriter writer)
        {
            WebControl corner = this.FpSpread1.FindControl("corner") as WebControl;
            corner.Attributes.Add("onmousedown", "return CornerClick()");
            base.Render(writer);
        }
    复制代码
    VB.NET
 
Protected Overrides Sub Render(writer As HtmlTextWriter)
    Dim corner As WebControl = TryCast(Me.FpSpread1.FindControl("corner"), WebControl)
    corner.Attributes.Add("onmousedown", "return CornerClick()")
    MyBase.Render(writer)
End Sub
复制代码
第二步:
添加客户端 JS 代码
 
<script type="text/javascript">
        function CornerClick() {
            event.cancelBubble = true;
            event.returnValue = false;
            return false;
        }
    </script>
