检索的GridView行数据到一个asp.net的形式 [英] retrieve data from gridview row to an asp.net form

问题描述

我想通过点击的ImageButton（预订）来检索GridView控件中的一行：
这里是我的网格视图的code：

 ＆LT; ASP：GridView控件ID =GridView1=服务器HEIGHT =150像素WIDTH =284px
                         的CssClass =TB的AutoGenerateColumns =FALSE的DataSourceID =SqlDataSource1＆GT;                         ＆LT;柱体和GT;
                          ＆LT; ASP：的TemplateField的HeaderText =预订＆GT;
                         ＆LT;＆ItemTemplate中GT;
                              ＆LT; ASP：ImageButton的ID =预订=服务器的HeaderText =预定的ImageUrl =booking_icon.ico一项PostBackUrl =form.aspx/＆GT;
                         ＆LT; / ItemTemplate中＆GT;
                         ＆LT; / ASP：的TemplateField＆GT;                            ＆LT; ASP：BoundField的数据字段=贸易的HeaderText =贸易SORTEX pression =交易/＆GT;
                             ＆LT; ASP：BoundField的数据字段=承运人的HeaderText =航母
                                 SORTEX pression =载体/＆GT;
                            ＆LT; /专栏＆GT;
 ＆LT; / ASP：GridView的＆GT;
 

在form.aspx页应该从gridview的行提交的文本框：

 ＆LT; ASP：文本框ID =以旧换新=服务器的CssClass =输入焦点＆GT;＆LT; / ASP：文本框＆GT;
＆LT; ASP：文本框ID =航母=服务器的CssClass =输入焦点＆GT;＆LT; / ASP：文本框＆GT;
 

解决方案

添加GridView的RowCommand事件和图像按钮命令参数，你可以传递一个ID或东西来判断当前行。

 ＆LT; ASP：GridView的onrowcommand =gvRowCommandID =GridView1=服务器HEIGHT =150像素WIDTH =284px
                     的CssClass =TB的AutoGenerateColumns =FALSE的DataSourceID =SqlDataSource1＆GT;
 ＆LT;＆ItemTemplate中GT;
    ＆LT; ASP：ImageButton的CommandArgument ='＆LT;％＃的eval（SomeId）％＆GT;' ID =预订=服务器的HeaderText =预定的ImageUrl =booking_icon.ico/＆GT;
＆LT; / ItemTemplate中＆GT;
 

C＃

 保护无效gvRowCommand（对象发件人，GridViewCommandEventArgs E）
   {
      VAR someId = e.CommandArgument;
   }
 

VB.Net

 保护小组gvRowCommand（BYVAL发件人为对象，BYVAL E上System.Web.UI.WebControls.GridViewCommandEventArgs）处理gv.RowCommand   昏暗someId作为整数= Convert.ToInt32（e.CommandArgument）结束小组

I would like to retrieve a row from the gridview by clicking on ImageButton (Booking): here is the code of my grid view:

    <asp:GridView ID="GridView1" runat="server" Height="150px" Width="284px" 
                         CssClass="tb" AutoGenerateColumns="False" DataSourceID="SqlDataSource1">

                         <Columns>
                          <asp:TemplateField HeaderText=" Booking">
                         <ItemTemplate>
                              <asp:ImageButton ID="booking" runat="server"   HeaderText="Booking" ImageUrl="booking_icon.ico" PostBackUrl="form.aspx"/>
                         </ItemTemplate>
                         </asp:TemplateField>

                            <asp:BoundField DataField="Trade" HeaderText="Trade" SortExpression="Trade" />
                             <asp:BoundField DataField="CARRIER" HeaderText="CARRIER" 
                                 SortExpression="CARRIER" />
                            </Columns>
 </asp:GridView>

The textbox of the form.aspx page that should be filed from the gridview row:

<asp:TextBox ID="trade" runat="server" CssClass="input , focus"></asp:TextBox>
<asp:TextBox ID="carrier" runat="server" CssClass="input , focus"></asp:TextBox>

解决方案

Add GridView RowCommand event and command argument for image button where you can pass an id or something to determine the current row.

  <asp:GridView  onrowcommand="gvRowCommand" ID="GridView1" runat="server" Height="150px" Width="284px" 
                     CssClass="tb" AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
 <ItemTemplate>
    <asp:ImageButton  CommandArgument='<%# Eval("SomeId") %>' ID="booking" runat="server"   HeaderText="Booking" ImageUrl="booking_icon.ico" />
</ItemTemplate>

C#

   protected void gvRowCommand(object sender, GridViewCommandEventArgs e)
   {
      var someId = e.CommandArgument;
   }

VB.Net

 Protected Sub gvRowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gv.RowCommand

   Dim someId As Integer = Convert.ToInt32(e.CommandArgument)

End Sub
