ASP.NET: How to hide ListBox control vertical scro

问题:

I have tried CSS: overflow: auto. It doesn't work. Any way to achieve it?

Do I need to create my custom control as I have seen it on ASP.NET forum?

回答1:

I would go with creating a custom control like you mentioned.

What is your desired goal? Creating your own scrollbar to put in the listbox?

回答2:

this should work:

listBox1.Rows = listBox1.Items.Count;

it causes all items are visible is SELECT html tag. You can place it to your own div set overflow and make your own scrollbars if you want.

this work for me

listBox1.DataSource = ....
listBox1.DataBind();
listBox1.Rows = listBox1.Items.Count + 1;

.

<div Class="divBorderCSS">
    <asp:listbox id="lbPCList" runat="server" DataTextField="Text" DataValueField="Value" selectionmode="Multiple" CssClass="lbCSS">
    </asp:listbox>

.

.listboxCSS
{
    font-size: 8pt;
    font-family: Arial;
    border:0;
    overflow:auto;
}

.divBorderCSS
{
    border-left-width:thin;
    border-right-width: thin;
    border-top:thin;
    border-bottom: thin;
    border-color: #7F9DB9;
    border-style:solid;
    overflow:auto;
    width: 300px;
    height: 100px;
    POSITION: relative;
}

Using jQuery:

<asp:ListBox
    ClientSideEvents-Init="function(s,e){$(s.GetMainElement()).find('div:first').css('overflow','hidden');}"
    ... />
