如何在网格中单击按钮以获取垂直细胞值 [英] how to get perticular cell value on button click which is in grid veiw

问题描述

我有一个带有按钮字段的gridview

当我单击一个按钮时，应该使面板可见，而该面板不在网格内，同时我想访问该垂直行的单元格值之一

在网格中，我正在显示

辅助cid cname名称和按钮字段

当我按一下按钮时，panal应该可见，并且我希望cid值存储在一个变量中.


这是我的网格

       <AlternatingRowStyle BackColor="White" />
       <Columns>
           <asp:TemplateField HeaderText="Appointment Id">
           <ItemTemplate>
               <asp:Label ID="Label1" runat="server" Text='<%#Eval("Appointment_ID") %>'></asp:Label>
               </ItemTemplate>
           </asp:TemplateField>
           <asp:TemplateField HeaderText="Appointment date">
           <ItemTemplate>
               <asp:Label ID="Label2" runat="server" Text='<%#Eval("Appointment_Date") %>'></asp:Label>
               </ItemTemplate>
           </asp:TemplateField>
           <asp:TemplateField HeaderText="Start Time">
           <ItemTemplate>
               <asp:Label ID="Label3" runat="server" Text='<%#Eval("Start_Time") %>'></asp:Label>

               </ItemTemplate>
           </asp:TemplateField>
           <asp:TemplateField HeaderText="End Time">
           <ItemTemplate>
               <asp:Label ID="Label4" runat="server" Text='<%#Eval("End_Time") %>'></asp:Label>

               </ItemTemplate>
           </asp:TemplateField>
           <asp:TemplateField HeaderText="Consumer Id" Visible="false">

               <asp:Label ID="Label5" runat="server" Text='<%#Eval("Consumer_Id") %>'></asp:Label>

               </ItemTemplate>
           </asp:TemplateField>
            <asp:TemplateField HeaderText="Consumer Name">
                <ItemTemplate>
                    <asp:Label ID="Label6" runat="server" Text='<%#Eval("First_Name") %>'></asp:Label>
                </ItemTemplate>
           </asp:TemplateField>
            <asp:TemplateField HeaderText="No. Of Friends">
           <ItemTemplate>
               <asp:Label ID="Label7" runat="server" Text='<%#Eval("NO_OF_FRIENDS") %>'></asp:Label>
               </ItemTemplate>
           </asp:TemplateField>


           <asp:TemplateField>
           <ItemTemplate>
               <asp:Button ID="Button2" runat="server" Text="Deploy" OnClick="btn_click" /></ItemTemplate>
           </asp:TemplateField>
       </Columns>
       <EditRowStyle BackColor="#2461BF" />
       <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
       <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
       <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
       <RowStyle BackColor="#EFF3FB" />
       <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
       <SortedAscendingCellStyle BackColor="#F5F7FB" />
       <SortedAscendingHeaderStyle BackColor="#6D95E1" />
       <SortedDescendingCellStyle BackColor="#E9EBEF" />
       <SortedDescendingHeaderStyle BackColor="#4870BE" />
   </asp:GridView>

这是代码

and this is the code

protected void btn_click(object sender, EventArgs e)
   {
        Panel1.Visible = true;
        int cid = Convert.ToInt32(GridView1.SelectedRow.Cells[4].Text);
        Lblcid.Text = cid.ToString();

   }

请帮忙.

please help .

推荐答案

尝试:

<asp:TemplateField>
   <ItemTemplate>
           <asp:Button ID="Button1" runat="server" CommandArgument='<%#Eval("consumer_id")%>' Text="Submit" OnClick="Button1_Click" />
   </ItemTemplate>
</asp:TemplateField>

然后，您可以在后面的代码中像这样检索它:

You can then retrieve it like this in the code behind:

protected void Button1_Click(object sender, EventArgs e)
{
  Button myButton = sender as Button;
  if (myButton != null)
  {
     string consumerID = myButton.CommandArgument;
     // use this title now to set as a text for your label.
     // use the consumer id
     // show the needed panel
  }
}

发送者持有对触发事件处理程序的Button的引用.

The sender holds a reference to the Button that triggered the event handler.
