如何为Web用户控件的属性赋值。 [英] How to assign value to the property of web user control.

问题描述

我创建了一个Web用户控件并创建了它的属性。

I have created one web user control and created its property as well.

public string Volume
{
    get
    {
        return Session["VOLUME"].ToString();
    }
    set
    {
        Session["VOLUME"] = value;
    }
}

现在，我已将此网络用户控件放在转发器中。

当我是试图在Repeater中搜索Web用户控件的这个卷属性，我没有得到这个，我到目前为止尝试的代码：

now, i have placed this web user control in a Repeater.
when i'm trying to search for this "Volume" property of Web User Control in Repeater, i'm not getting this, code i tried so far:

if (Repeater1.Items[index].ItemType == ListItemType.Item || Repeater1.Items[index].ItemType == ListItemType.AlternatingItem)
{
    Repeater r1 = Repeater1.Items[index].FindControl("Repeater1") as Repeater;
    if (r1 != null)
    {
        foreach (RepeaterItem item in r1.Items)
        {
            UserControl u = (UserControl)item.FindControl("SubChemicals1");
            if (u != null)
            {
                u.;// Not able to get the property of userscontrol which i defined
            }
        }
    }
}

有谁能帮助我获取此UserControl的属性？

Can anyone please help me to get the property of this UserControl?

推荐答案

你需要添加一些如下所示的属性

you need to add few attributes like below

[EditorBrowsable(EditorBrowsableState.Always)]
[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public string Volume
        {
            get
            {
                return Session["VOLUME"].ToString();
            }
            set
            {
                Session["VOLUME"] = value;
            }
        }

当你施放时，你需要施放它对你的用户控制如下（假设你的用户控件类名是SubChemicals

when you cast, you need to cast it to your user control like below ( assume your user control class name is SubChemicals

SubChemicals u = (SubChemicals)item.FindControl("SubChemicals1");
