GridView编辑-在文本框/下拉列表中输入后的新值 [英] GridView edit - new values after wirte in textbox/dropdownlist

问题描述

我在gridview中的编辑日期有问题.当我编辑gridview时，我想更新单元格之一.因此，在此单元格中输入新值，问题是我不知道如何下载此新值，因为比我这样写道:

I have problem with edit date in gridview.When I edit gridview i want update one of cell. So enter new value in this cell, and problem is that i don''t have any idea how can i download this new value because than i write:

(textbox)(gridview.Rows(e.RowIndex).Cells[2].Control[0]).Text.ToString()

我下载的是旧值而不是新值.
有人可以帮我吗?

This link didn''t help i still have this problem.
I change text box to dropdown list but i have still this problem.
Now i have something like tihs :

<Columns>
                        <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
                        <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" 
                            SortExpression="ID" />
                            <asp:TemplateField>
                                <ItemTemplate>
                                    <asp:Label ID="Teacher_name" runat="server" Text=''<%# Eval("Teacher_name") %>''></asp:Label>
                                </ItemTemplate>
                                <EditItemTemplate> 
                                    <asp:DropDownList ID="ddlEditTeacher" runat="server" 
                                        DataSourceID="SqlDataSource1" DataTextField="Teacher_name"  
                                        DataValueField="Teacher_name" 
                                      ></asp:DropDownList>
                                    <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
                                        ConnectionString="<%$ ConnectionStrings:DiaryConnectionString %>" 
                                        SelectCommand="SELECT Teachers.name+'' ''+Teachers.surname AS[Teacher_name] FROM Teachers">
                                    </asp:SqlDataSource>
                                </EditItemTemplate>
                            </asp:TemplateField>

但是当我编辑项目时，我仍然可以使用新的选择值.例如，如果下拉列表必须具有值"A"和"B".现在在网格视图中是值"A".当我想更改此值时，单击编辑"，然后在下拉列表值"B"中选择，但在编写gbr_RowUpdating函数时写入

but still when i edit item i can use new select values. For example if drop down list have to values "A" and "B". Now in grid view is value "A". When i want change this value, i click on edit and select in drop down list value "B" but in function gv_RowUpdating when i write

GridViewRow row = gvMajor.Rows[e.RowIndex];
                string text=
                ((DropDownList) (row.Cells[3].FindControl(ddlEditTeacher)).SelectedValues;

我仍然值"A"而不是"B"为什么?

I have still value "A" not "B" why ?

推荐答案

ConnectionStrings:DiaryConnectionString％> SelectCommand ="SELECT Teachers.name +''''+ Teachers.surname AS [Teacher_name] FROM Teachers"> </asp:SqlDataSource> </EditItemTemplate> </asp:TemplateField>

ConnectionStrings:DiaryConnectionString %>" SelectCommand="SELECT Teachers.name+'' ''+Teachers.surname AS[Teacher_name] FROM Teachers"> </asp:SqlDataSource> </EditItemTemplate> </asp:TemplateField>

但是当我编辑项目时，我仍然可以使用新的选择值.例如，如果下拉列表必须具有值"A"和"B".现在在网格视图中是值"A".当我想更改此值时，单击编辑"，然后在下拉列表值"B"中选择，但在编写gbr_RowUpdating函数时写入

                string text=
                ((DropDownList) (row.Cells[3].FindControl(ddlEditTeacher)).SelectedValues;

我仍然值"A"而不是"B"，为什么?

I have still value "A" not "B" why ?
