Question

DataGrid 编辑的时候，怎样限制 TextBox 模板的宽度？ 我不会设置,那TextBox总是特别宽，弄得整个DataGrid都很宽，不好看了。((TextBox)e.Item.Cells[1].Controls[1]).Width = 80;我这样设置也不行。出现这个错误 “指定的参数已超出有效值的范围。参数名: index”请帮帮我！ 在线等！

Answer 1

使用模板列
Width="100px" Text='<%# DataBinder.Eval(Container, "DataItem.CName") %>'

Answer 2

<asp:TemplateColumn HeaderText="分类名">
<ItemTemplate>
<asp:Label id=Label1 runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.CName") %>'>
</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox id=txtName runat="server" Width="100px" Text='<%# DataBinder.Eval(Container, "DataItem.CName") %>' MaxLength="12">
</asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>

            orderid = e.Item.ItemIndex + 1            If e.Item.ItemType = ListItemType.EditItem Then
                For i = 0 To 12
                    t(i) = CType(e.Item.Cells(i).Controls(0), TextBox)
                    t(i).CssClass = "CssStyle1"
                    Select Case i
                        Case 0
