我有一个显示产品信息的gridview（下面的代码） 现在我想限制描述字段，以便只有前几个显示，如果有一个长描述，并调整图像大小以适应图像列（并使图像，描述列比其他列大一点
由于
<asp:GridView ID="gvProducts" runat="server" AutoGenerateColumns="False" DataKeyNames="ProductId" OnRowDeleting="gvProducts_RowDeleting" OnSelectedIndexChanged="gvProducts_SelectedIndexChanged">
<Columns>
<asp:CommandField ShowSelectButton="True" />
<asp:BoundField DataField="Productname" HeaderText="Name" />
<asp:BoundField DataField="ProductDescription" HeaderText="Description" />
<asp:BoundField DataField="ProductSupplier" HeaderText="Supplier" />
<asp:BoundField DataField="ProductCategory" HeaderText="Category" />
<asp:BoundField DataField="ProductSubCategory" HeaderText="SubCategory" />
<asp:BoundField DataField="ProductVAT" HeaderText="VAT" />
<asp:BoundField DataField="ProductStock" HeaderText="Stock" />
<asp:ImageField DataImageUrlField="ProductImage" HeaderText="Image"/>
<asp:CheckBoxField DataField="ProductActive" HeaderText="Active" />
<asp:CommandField ButtonType="Button" ShowDeleteButton="True" />
</Columns>
<SelectedRowStyle CssClass="selectedrow" />
</asp:GridView>

使用 css ，我们可以限制要显示的说明文字。像这样....
<asp:GridView ID="gvProducts" runat="server" CssClass="GridCSS" AutoGenerateColumns="False" DataKeyNames="ProductId" OnRowDeleting="gvProducts_RowDeleting" OnSelectedIndexChanged="gvProducts_SelectedIndexChanged">
<Columns>
-----------------------
-----------
---------
<asp:BoundField DataField="ProductDescription" HeaderText="Description" ItemStyle-CssClass="limittext" />
------------------
---------
-------------
</Columns>
</asp:GridView>
CSS样式：
.GridCSS {
table-layout:fixed;
width:100%;
}
.GridCSS .limittext{
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}

你可以使用面膜为fw 4.5或一些外部插入lika Jquery面膜。 或者您可以将它们设为模板项并添加一些代码，例如＆lt;％＃Eval（“ProductDescription”）。SubString（0,50）％＆gt;

如果您正在使用MVC，您可以在将其绑定到GW之前更改控制器中的GridView数据。如果您不使用MVC，我唯一能提供的是：在您的RowDataBound事件中，检查描述是否超出您定义的最大值。 chars然后截断它。
我知道不是一个正确的答案，但它可能会给你一些想法。因为我在工作，现在无法提供代码，但如果您的帖子没有答案我会稍后检查。

试试这个
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<%# Eval("ProductDescription").ToString().Length > 50 ? Eval("ProductDescription").ToString().Substring(0,50)+"..." : Eval("ProductDescription").ToString() %>
</ItemTemplate>
</asp:TemplateField>
如果文字超过50个字符，则先显示50个字符，否则显示整个文字。
另一个选项是从数据库或Product对象
返回shortDescription public string ShortDescription
{
get
{
return ProductDescription.Length > 50 ? ProductDescription.Substring(0,50) : ProductDescription;
}
}
