如何将值传递给模态形式 [英] how to pass a value to modal form

问题描述

大家好，



我的主aspx表格中有以下代码。

Hi all,

I have the following code in my main aspx form.

<asp:button id="Button1" name="cmd_add_key" runat="server" OnClick="add_keys" Text="Attach keys" />
        <asp:ToolkitScriptManager ID="ToolkitScriptManager2" runat="server"></asp:ToolkitScriptManager>
        <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Panl1" DropShadow="true"

            TargetControlID="cmd_add_key" CancelControlID="cmd_cancel" ></asp:ModalPopupExtender>
        <asp:Panel ID="Panel1" runat="server" CssClass="#transparent" align="center" style = "display:none; background-color:White;">
            <iframe style=" width: 800px; height: 300px;" id="Iframe1" src="getKeysforAddUpdatePropertyKey.aspx?PropertyId=324" runat="server"></iframe>
            <br/>
            <asp:Button ID="Button2" runat="server" Text="Close" class="btn btn-primary"/>
        </asp:Panel>

以下是add_keys方法背后的代码

Following is the code behind of add_keys method

protected void add_keys(object sender, EventArgs e)
{
    string url = "getKeysforAddUpdatePropertyKey.aspx?PropertyId=" + txt_property_id.Text;
    irm1.Attributes["src"] = url;
}

现在每次调用表单时，我都会得到值324，我理解这是页面中的默认值。然而，我正在寻找一种可以改变价值的方法。我认为通过在add_keys方法中编写代码可以解决问题，但是它完全被忽略了，我总是得到324.



任何帮助都将不胜感激。



非常感谢提前

Now every time I call the form, I get the value 324 which I understand is the default value in page. I am however looking for a way where I can change the value. I thought by writing the code in add_keys method will do the trick, however it is completely ignored and I always get 324.

Any help would be appreciated.

Many thanks in advance

管理自己解决问题。希望它会帮助别人



我将代码从add_keys方法移动到ModalPopupExtender的加载方法（mp1）

Managed to solve the problem myself. Hope it will help someone else

I moved the code from add_keys method to load method of ModalPopupExtender (mp1)

protected void mp1_Load(object sender, EventArgs e)
{
    string url = "getKeysforAddUpdatePropertyKey.aspx?PropertyId=" + txt_property_id.Text;
    irm1.Attributes["src"] = url;
}

在前端（aspx页面）改变了

On the front end (aspx page) changed

<asp:ModalPopupExtender ID="mp1" runat="server" PopupControlID="Panl1" DropShadow="true"

    TargetControlID="cmd_add_key" CancelControlID="cmd_cancel"

    </asp:ModalPopupExtender>

to

to

<asp:ModalPopupExtender ID="mp1" runat="server" PopupControlID="Panl1" DropShadow="true"

    TargetControlID="cmd_add_key" CancelControlID="cmd_cancel"

    onload="mp1_Load"></asp:ModalPopupExtender>
