Asp.NET中弹出窗体与父窗体之间的传值

经常遇到从弹出窗体与父窗体之间的传值问题，特别是在弹出窗体中的含有GridView控件的传值。在下面的例子中，我们将使用两个表单，父表单在PopupWindowPassValue.aspx中和弹出表单在PopupPage.aspx中;代码分为vb.Net和C#.Net

--- .aspx of parent form ---

<script type="text/javascript">

function OpenPopup() {

    window.open("popup.aspx","List","scrollbars=no,resizable=no,width=400,height=280");

    return false;

}

</script>

.      

.

.      

<asp:TextBox ID="txtPopupValue" runat="server" Width="327px"></asp:TextBox>

<asp:Button ID="Button1" runat="server" Text="Show List" />

--- .vb of parent.aspx if vb.net is the language ---

If Not IsPostBack Then

    Me.Button1.Attributes.Add("onclick", "javascript:return OpenPopup()")

End If

--- .cs of parent.aspx if C#.net is the language ---

if (!IsPostBack) {

    this.Button1.Attributes.Add("onclick", "javascript:return OpenPopup()");

}

--- .aspx of popup form ---

<script language="javascript">

function GetRowValue(val)

{

    // hardcoded value used to minimize the code.

    // ControlID can instead be passed as query string to the popup window

    window.opener.document.getElementById("ctl00_ContentPlaceHolder1_TextBox2").value = val;

    window.close();

}

</script>

 

 

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1">

    <Columns>

        <asp:TemplateField>

            <AlternatingItemTemplate>

                <asp:Button ID="btnSelect" runat="server" Text="Select" />

            </AlternatingItemTemplate>

            <ItemTemplate>

                <asp:Button ID="btnSelect" runat="server" Text="Select" />

            </ItemTemplate>

        </asp:TemplateField>

    </Columns>

</asp:GridView>

--- .vb file if vb.net is the language ---

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e AsSystem.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

    If (e.Row.RowType = DataControlRowType.DataRow) Then

        'assuming that the required value column is the second column in gridview

        DirectCast(e.Row.FindControl("btnSelect"), Button).Attributes.Add("onclick","javascript:GetRowValue('" & e.Row.Cells(1).Text & "')")

    End If

End Sub

--- .cs file if C#.net is the language ---

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) {

    if ((e.Row.RowType == DataControlRowType.DataRow)) {

        //assuming that the required value column is the second column in gridview

        ((Button)e.Row.FindControl("btnSelect")).Attributes.Add("onclick","javascript:GetRowValue('" + e.Row.Cells[1].Text + "')");

    }

}
