解决方案

的文本框都没有的TextMode 设置为多。结果
在的TextMode 属性设置为多上要显示为textarea的文本框。

例如：

 ＆LT;＆EditItemTemplate的GT;
  ＆LT; ASP：文本框ID =txtCategoryName列=50行=5=服务器的TextMode =多行文本='＆LT;％＃绑定（类别名称）％＆GT;'＆GT;＆LT ; / ASP：文本框＆GT;
＆LT; / EditItemTemplate中＆GT;
 

修改

和使烟标，尝试添加一个ItemStyle它，就像这样：

 ＆LT; ItemStyle换行=真WIDTH =200/＆GT;

            PageSize="5" OnRowDataBound="GridView1_RowDataBound">
            <Columns>                       
                <asp:TemplateField HeaderText="CategoryID" InsertVisible="False" SortExpression="CategoryID">
                    <ItemTemplate>
                        <asp:Label ID="lblCategoryID" runat="server" Text='<%# Bind("CategoryID") %>'></asp:Label>
                    </ItemTemplate>                  
                </asp:TemplateField>
                <asp:TemplateField HeaderText="CategoryName" SortExpression="CategoryName">

                    <ItemTemplate>
                        <asp:Label ID="lblCategoryName" runat="server" Text='<%# Bind("CategoryName") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Description" SortExpression="Description">
                    <EditItemTemplate>
                        <asp:TextBox ID="txtDesc" runat="server" Text='<%# Bind("Description") %>'></asp:TextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="lblDesc" runat="server" Text='<%# Bind("Description") %>'></asp:Label>
                    </ItemTemplate>                               
                </asp:TemplateField>               
            </Columns>
        </asp:GridView>

解决方案

None of the textboxes have TextMode set to Multiline.
Set the TextMode property to Multiline on the textbox that you want to be displayed as textarea.

e.g:

<EditItemTemplate>                         
  <asp:TextBox ID="txtCategoryName"  Columns="50" Rows="5" runat="server" TextMode="MultiLine" Text='<%# Bind("CategoryName") %>'></asp:TextBox>                     
</EditItemTemplate>

EDIT

And to make the label wrap, try adding an ItemStyle to it, like this:

<ItemStyle Wrap="true" Width="200" />
