这是因为你没有对DataGrid的每一项设定好宽度。

Answer 2

将DataGrid中每一列中的控件设定一个固定长度即可.

<ASP:DataGrid id="MyDataGridzc" runat="server"
                                 Width="400"

                                 OnCancelCommand="MyDataGridzc_Cancel" 
                                 OnUpdateCommand="MyDataGridzc_Update"
                                 AutoGenerateColumns="false" 
                              >

                            <asp:TemplateColumn HeaderText="数量" SortExpression="数量">
                              <ItemTemplate>
                        <asp:Label runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "数量") %>' ID="Label1" NAME="Label1"/>
                      </ItemTemplate>
                      <EditItemTemplate>
                <nobr>
//******** width="40" height="18" ******
                <asp:TextBox runat="server"  width="40" height="18"  id="edit_zcsl" Text='<%#DataBinder.Eval(Container.DataItem, "数量") %>'/>
                      </EditItemTemplate>
                            </asp:TemplateColumn>
                                    <asp:BoundColumn HeaderText="单位" DataField="单位" ReadOnly="True" ItemStyle-Wrap="false"/>

Answer 4

怎么不行？
如果你设置的DataGrid宽度不够的话，在修改时可以出现宽度修改的问题。但是如果把文本框的大小设定好，应该没有问题。

Answer 5

我找上面各位说的都修改过了，但是在编辑状态下，textbox文本域宽度还是变的很宽，有没有谁有具体的例子？？？？

Answer 6

后台可以
 Private Sub DataGrid_ItemCreated(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles Datagrid.ItemCreated
    Select Case e.Item.ItemType           Case ListItemType.EditItem  
           CType(e.Item.Cells(6).Controls(0), TextBox).Width = System.Web.UI.WebControls.Unit.Pixel(40)     
    End Select 
end sub
宽度多少在pixel里定吧

Answer 7

DataGrid的Width不设
在columns属性中，为每一列设它的width值。

Answer 8

改成模板列，编辑模板列，想怎么改就怎么改啊。NND,好像只有这样了

Answer 9

这样就可以了：  绝对没问题
private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
        {
             if(e.Item.ItemType==ListItemType.EditItem)
            {
                    for(int i=0;i<=5;i++)((TextBox)e.Item.Cells[i].Controls[0]).Width=60;
            }
        }
