非常快速的问题 - 我一定没有正确看到它,但是为什么 ASP 按钮“btnEdit”在 gridview 中仍然可见?在 RowDatabound (用于测试)上,我只是想隐藏它,并计划稍后在它周围放置一个 if 语句。

后面的代码(RowDataBound)

    protected void gvEditUser_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Button btnEdit = (Button)e.Row.FindControl("btnEdit");
        btnEdit.Visible = false;
        if (e.Row.RowState != null)
        {
            if ((e.Row.RowState & DataControlRowState.Edit) > 0)
            {

                CheckBox cbAdmin = (CheckBox)e.Row.FindControl("cbAdmin");
                DataRowView dr = e.Row.DataItem as DataRowView;
                if (Convert.ToBoolean(dr["admin"] = true))
                {
                    cbAdmin.Checked = true;
                }
                else
                {
                    cbAdmin.Checked = false;
                }
            }
        }
    }
}

我忘了在 gridview 上订阅 OnRowDataBound。不是一个聪明的家伙......

绑定上的隐藏按钮(可以使用偶数条件)

<asp:GridView ID="GridView1" runat="server"  AutoGenerateColumns="false" OnRowCommand="grd_finantial_year_RowCommand"    DataKeyNames="srno" >
    <Columns>                           
        <asp:TemplateField HeaderText="Change Status">
            <ItemTemplate>                                  
                <asp:LinkButton ID="btnststact" Visible='<%#BtnVisibility(Eval("active").ToString(),"StatusACT")%>' Text="ACTIVATE" runat="server" CommandName="StatusACT" CommandArgument='<%#Eval("srno")%>' /> 
            </ItemTemplate>
        </asp:TemplateField>                   
    </Columns>
</asp:GridView>

只需在具有公共访问级别的 C# 中添加此函数

public Boolean BtnVisibility(string StatusNo, string ButtonName) { // 0 means not active, 1 means activated

  if (ButtonName == "StatusACT") {
     if (StatusNo == "0") {//not active
        return true;
     }
     else if (StatusNo == "1") //active
     {
        return false;
     }
  }
return true;
}
