我的脚本

<asp:Repeater ID="myrepeater" runat="server">
        <HeaderTemplate>
            <table style="font: 8pt verdana">
                <tr style="background-color:#3C78C3">

                </tr>

        </HeaderTemplate>
        <ItemTemplate>
            <tr>
                <td>
                    <%#DataBinder.Eval(Container,"DataItem.allun")%>
                    <asp:Button ID="Button1" runat="server" Text="Button" />
                </td>
           </tr>

隐藏代码

protected void btnSearch_Click(object sender, EventArgs e)
{
    con.Open();
    if (txtSearch.Text != "")
    {
        SqlDataAdapter mycommand = new SqlDataAdapter("select * from WebAdminTable where allun='" + txtSearch.Text + "'", con);
        DataSet ds = new DataSet();
        mycommand.Fill(ds);
        myrepeater.DataSource = ds;
        myrepeater.DataBind();
    }
    else
    {
        //msgbox for entering value
    }
    con.Close();
}

protected void btnAddToMyFList_Click(object sender, EventArgs e)
{
      //?
}

推荐答案

您可以将 userName 绑定到标签控件，然后单击按钮即可访问标签控件的值，例如...

You can bind the userName to a label control and then you can access the value of the label control on the click of button like...

protected void btnAddToMyFList_Click(object sender, EventArgs e)
{
  Button btnAddToMyFList = (Button)sender;
  Label label = (Label)btnAddToMyFList.Parent.FindControl("LabelId");
  String labelText = label.Text; //userName of clicked row
}
