大家好，

Hi All,

I have a ASP.Net menu that appears horizontally on click of each tree node of a treeview.

It has got sub menus and it is displaying properly.

The problem is when i am on the sub menus, the parent menu disappears and the sub menu only is displaying.

Can somebody please help me!!

推荐答案

您的Menu代码库中有一些问题.调查一下.如果您没有得到它，而只需要对该菜单控件进行修复，请尝试发布重要的代码片段以供查看.

否则，您可以查看在codeproject上发布的许多菜单控件之一.选择一个适合您的.
例如:
ASP.NET水平菜单控件 [非常兼容的DHTML菜单ASP.NET用户控件 [

There is some issue in your codebase of Menu. Look into that. If you don''t get it and need a fix on that menu control only, try posting important snippets of it to look at.

Otherwise, you can have a look at one of many Menu controls present published here at codeproject. Pick the one that suits you.
For example:
ASP.NET Horizontal Menu Control[^]
Very Compatible DHTML Menu ASP.NET User Control[^]

Thanks for the reply Sandeep!!

Following is my code:

Javascript:

function showhide(obj,onlink,arg)
        {
            targetObject = document.getElementById(obj).style;

            globalObject = targetObject;
            if(onlink)
            {
                clearTimeout(ourTimer);
                for (i=0; i < menuArray.length; i++)
                {
                    var tempObject = document.getElementById(menuArray[i]).style;
                    tempObject.visibility = "hidden";
                }
                targetObject.visibility = 'visible';
                targetObject.position = "absolute";
                var x = getPosition(event).x;
                var y = getPosition(event).y;
                if (y > 490 && y < 590)
                {
                    targetObject.top = getPosition(event).y - 90;
                    targetObject.left = getPosition(event).x;
                }
                else
                {
                    targetObject.top = getPosition(event).y;
                    targetObject.left = getPosition(event).x;
                }
                isActive = true;
            }
            else
            {
                isActive = false;
                layerTimer();
            }
        }

ASP.Net:

ASP.Net:

<asp:Menu ID="menuHover" BackColor="LightCyan" runat="server" DisappearAfter="900"

                style="visibility:hidden; position:absolute; top:0; left:0; z-index: 999;">
        <Items>
            <asp:MenuItem Text="Option1" Value="Option1" >
                <asp:MenuItem Text="Option 1.1" Value="test1"></asp:MenuItem>
                <asp:MenuItem Text="Option 1.2" Value="test2"></asp:MenuItem>
                <asp:MenuItem Text="Option 1.3" Value="test3"></asp:MenuItem>
            </asp:MenuItem>
            <asp:MenuItem Text="Option2" Value="Option2" ></asp:MenuItem>
            <asp:MenuItem Text="Option3" Value="Option3">
                <asp:MenuItem Text="Option 3.1" Value="Option 3.1"></asp:MenuItem>
                <asp:MenuItem Text="Option 3.2" Value="Option 3.2"></asp:MenuItem>
                <asp:MenuItem Text="Option 3.3" Value="Option 3.3"></asp:MenuItem>
            </asp:MenuItem>
            <asp:MenuItem Text="Option4" Value="Option4"></asp:MenuItem>
        </Items>
    </asp:Menu>

这是一个非常简单的菜单结构，其中ShowHide()函数用于在鼠标悬停时填充菜单.

但是当我在子菜单上时，n如果我们将鼠标悬停在子菜单上一段时间，则会显示父菜单.

如果可以的话请帮帮我！

This is a very simple menu structure n the ShowHide() function is used to populate the menu on mouseover.

But when i am on the sub menus, n if we keep the mouse over the sub menu for some time, the parent menu is displaying.

Please help me, if possible!!

您是否已在所有浏览器上对其进行了检查?

我认为是与样式有关的问题.
如果您更改样式或背景色
的菜单控件，则可以解决您的问题.

Have u check it on all browser?

I think its style related problem.
if u change the style or backcolor
of menucontrol then it can solve ur problems.
