如何使我的gridview在页面上适应100%

Question

如何让我的gridview在屏幕内很好地适应.我添加了这个属性width ="100%"i.但是我的gridview仍然超出了我的标题宽度,我将其设置为100%.

这是我第一次尝试的gridview的源代码.

<asp:GridView ID="GWCase" runat="server"  Top="0%" Width="100%" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2" ForeColor="Black" Height="199px" AutoGenerateSelectButton="True" OnSelectedIndexChanged="GWCase_SelectedIndexChanged">

    <FooterStyle BackColor="#CCCCCC" />
    <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
    <PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" />
    <RowStyle BackColor="White" />
    <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
    <SortedAscendingCellStyle BackColor="#F1F1F1" />
    <SortedAscendingHeaderStyle BackColor="#808080" />
    <SortedDescendingCellStyle BackColor="#CAC9C9" />
    <SortedDescendingHeaderStyle BackColor="#383838" />
</asp:GridView>

我尝试使用这样的css方法

<ul id="assigngw">
<asp:GridView ID="GWCase" runat="server"  Top="0%" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2" ForeColor="Black" Height="199px" AutoGenerateSelectButton="True" OnSelectedIndexChanged="GWCase_SelectedIndexChanged">

    <FooterStyle BackColor="#CCCCCC" />
    <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
    <PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" />
    <RowStyle BackColor="White" />
    <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
    <SortedAscendingCellStyle BackColor="#F1F1F1" />
    <SortedAscendingHeaderStyle BackColor="#808080" />
    <SortedDescendingCellStyle BackColor="#CAC9C9" />
    <SortedDescendingHeaderStyle BackColor="#383838" />
</asp:GridView>
    </ul>

Css代码:

#assigngw {
width:100%;
}

不幸的是两者都不起作用.

这是我的完整源代码.

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<link rel="stylesheet" href="css/style.css" type="text/css" />
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

<ul id="assigngw">
    <asp:GridView ID="GWCase" runat="server" width="300px" Top="0%" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2" ForeColor="Black" Height="199px" AutoGenerateSelectButton="True" OnSelectedIndexChanged="GWCase_SelectedIndexChanged">

    <FooterStyle BackColor="#CCCCCC" />
    <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
    <PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" />
    <RowStyle BackColor="White" />
    <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
    <SortedAscendingCellStyle BackColor="#F1F1F1" />
    <SortedAscendingHeaderStyle BackColor="#808080" />
    <SortedDescendingCellStyle BackColor="#CAC9C9" />
    <SortedDescendingHeaderStyle BackColor="#383838" />
</asp:GridView>
    </ul>

Answer 1

问题出在您的测试内容和垃圾文本上.

加:

#assigngw td {
  word-wrap:break-word;
}

这将允许每个单元格在不适合的长句子上打破并且将阻止它增加网格视图的大小.

编辑

试试这个

.gridview {
    width: 100%; 
    word-wrap:break-word;
    table-layout: fixed;
}

这里的关键是table-layout: fixed;它迫使细胞适应桌子而不是桌子扩展以适应细胞.
