Question

我已动态创建DataTable来绑定GridView。我有两个按钮，它们的可见性设置为false。我希望当我在按钮单击上添加新行时，我希望其中一个按钮在该新行中设置visibility = true，另一个按钮保持可见性= false。因此，该按钮应仅对用户添加的行可见，在DataTable的所有行中不可见。这是我的代码，我不知道如何解决这个问题。请帮忙

标记：

  <asp:GridView ID="GridView2"  runat="server" OnRowDataBound="GridView2_RowDataBound">
        <Columns>
    <asp:TemplateField>
    <ItemTemplate>

             <asp:Button ID="Button189" Visible="false" OnClick="Button189_Click" runat="server" Text="odzemi svez vrganj" />

             <asp:Button ID="btnTest" Visible="false"   runat="server" CommandName="odzemi" CssClass="button2" OnClick="btnTest_Click" Text="-" Width="100px" Font-Bold="True" />

         </ItemTemplate>
    </asp:TemplateField>

            </Columns>
                   </asp:GridView>

代码背后：

 protected void Button5_Click(object sender, EventArgs e)
    {
        MethodForAddFirstRow();
       //Here i need somehow to set bnTest to be visible only for this row,other button to stay invisible
    }
    protected void Button5_Click(object sender, EventArgs e)
    {
        MethodForAddSecondRow();
       //Here I need somehow to set Button189 to be visible only for this row,other button to stay invisible
    }

为了处理网格内按钮的事件，您需要使用OnRowCommand，因此您需要将网格更新为如下所示

<asp:GridView ID="GridView2"  runat="server" OnRowDataBound="GridView2_RowDataBound" onrowcommand="gv_RowCommand">

并确保每个按钮都具有CommandName属性，如下所示

<asp:Button ID="Button189" Visible="false" OnClick="Button189_Click" runat="server" Text="odzemi svez vrganj" CommandName="Command1" />

<asp:Button ID="btnTest" Visible="false"   runat="server" CommandName="Command2" CssClass="button2" OnClick="btnTest_Click" Text="-" Width="100px" Font-Bold="True" />

然后在

后面的代码中创建以下事件处理程序

 void gv_RowCommand(Object sender, GridViewCommandEventArgs e)
  {
     if(e.CommandName=="Command1")
     {
     }
     else if(e.CommandName=="Command2")
     {
     }
  }

要访问rowcommand事件处理程序中的按钮，您可以使用以下

GridView customersGridView = (GridView)e.CommandSource;
GridViewRow row = customersGridView.Rows[index];
Button btn = (Button)row.FindControl("Button189");
btn.Visible=false;
