问题描述

当在GridView控件pressing编辑按钮,显示编辑模板后,才2次点击。
而另一个问题:现场编辑的值最初显示在GridView控件,但不是在编辑模板

天冬氨酸code:

 < ASP:GridView控件ID =GridView1=服务器AllowPaging =真AllowSorting =真
的AutoGenerateColumns =假CELLPADDING =4OnRowEditing =EditRow
OnRowCancelingEdit =CancelEditRow的DataKeyNames =AREA的DataMember =默认视图>  <柱体和GT;
     < ASP:BoundField的数据字段=AREA的HeaderText =AREA只读=真
                                        SORTEX pression =AREA/>      < ASP:的TemplateField的HeaderText =LEADER_USERSORTEX pression =LEADER_USER>
                     <&ItemTemplate中GT;<%#的eval(leader_user)%>< / ItemTemplate中>
                      <&EditItemTemplate的GT;
                          < ASP:文本框ID =txtleaderuser=服务器文本='<%#的eval(leader_user)%>/>
                      < / EditItemTemplate中>
       < / ASP:的TemplateField>       < ASP:的TemplateField>
           <&ItemTemplate中GT;
                  < ASP:ImageButton的ID =editButton=服务器的CommandName =编辑
                                                的ImageUrl =图片/ pencil1.png文本=编辑工具提示=编辑/>
            < / ItemTemplate中>
             <&EditItemTemplate的GT;
                   < ASP:按钮的ID =BtnUpdate=服务器的CommandName =更新
                                                文本=更新/>
                   < ASP:按钮的ID =BtnCancel=服务器的CommandName =取消
                                                文本=取消/>
              < / EditItemTemplate中>
             < / ASP:的TemplateField>      < /专栏>
    < / ASP:GridView的>

VB code:

 保护小组EditRow(BYVAL发件人为对象,BYVAL E上GridViewEditEventArgs)
        GridView1.EditIndex = e.NewEditIndex
        GridView1.DataSource = SqlDataSource1
        如果不是那么的IsPostBack
        GridView1.DataSourceID = SqlDataSource1.ID
        GridView1.DataBind()
        '万一
 结束小组保护小组的Page_Load(BYVAL发件人为对象,BYVAL E上System.EventArgs)把手Me.Load        SqlDataSource1.SelectCommand =SQL
        SqlDataSource1.ConnectionString =我康恩字符串        如果没有的IsPostBack然后
            GridView1.DataSourceID = SqlDataSource1.ID
            GridView1.DataSource = SqlDataSource1
            GridView1.DataBind()
        万一
    结束小组


解决方案

我认为你需要调用的DataBind 来重新绑定数据源。您已经评价出来,但它看起来像你在的IsPostBack 块,这将仅在初始页面加载执行了吧。

尝试:

 保护小组EditRow(BYVAL发件人为对象,BYVAL E上GridViewEditEventArgs)
    GridView1.EditIndex = e.NewEditIndex
    GridView1.DataSource = SqlDataSource1
    GridView1.DataBind()
结束小组

When pressing edit button in gridview, edit template is displayed only after 2 clicks.And another problem: Value of the field to edit is displayed in gridview initially, but not in edit template.

Asp code:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" CellPadding="4" OnRowEditing="EditRow"
OnRowCancelingEdit="CancelEditRow" DataKeyNames="AREA" DataMember="DefaultView">

  <Columns>
     <asp:BoundField DataField="AREA" HeaderText="AREA" ReadOnly="True"
                                        SortExpression="AREA" />

      <asp:TemplateField HeaderText="LEADER_USER" SortExpression="LEADER_USER">
                     <ItemTemplate><%#Eval("leader_user")%></ItemTemplate>
                      <EditItemTemplate>
                          <asp:TextBox ID="txtleaderuser" runat="server" Text='<%#Eval("leader_user")%>'/>
                      </EditItemTemplate>
       </asp:TemplateField>

       <asp:TemplateField>
           <ItemTemplate>
                  <asp:ImageButton ID="editButton" runat="server" CommandName="Edit"
                                                ImageUrl="images/pencil1.png" Text="Edit" ToolTip="Edit" />
            </ItemTemplate>
             <EditItemTemplate>
                   <asp:Button ID="BtnUpdate" runat="server" CommandName="Update"
                                                Text="Update" />
                   <asp:Button ID="BtnCancel" runat="server" CommandName="Cancel"
                                                Text="Cancel" />
              </EditItemTemplate>
             </asp:TemplateField>

      </Columns>
    </asp:GridView>

vb code:

Protected Sub EditRow(ByVal sender As Object, ByVal e As GridViewEditEventArgs)
        GridView1.EditIndex = e.NewEditIndex
        GridView1.DataSource = SqlDataSource1
        'If Not IsPostBack Then
        'GridView1.DataSourceID = SqlDataSource1.ID
        'GridView1.DataBind()
        'End If
 End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        SqlDataSource1.SelectCommand = "SQL"
        SqlDataSource1.ConnectionString = "My conn string"

        If Not IsPostBack Then
            'GridView1.DataSourceID = SqlDataSource1.ID
            GridView1.DataSource = SqlDataSource1
            GridView1.DataBind()
        End If


    End Sub
解决方案

I think you need to call DataBind to rebind the data source. You've commented it out, but it looks like you had it in a IsPostBack block, which would only execute on the initial page load.

Try:

Protected Sub EditRow(ByVal sender As Object, ByVal e As GridViewEditEventArgs)
    GridView1.EditIndex = e.NewEditIndex
    GridView1.DataSource = SqlDataSource1
    GridView1.DataBind()
End Sub
