RadAlert from User Control

[Dennis]

I have a simple user control (.ascx) that will contain an <asp:ImageButton> control. I would like to expose a property of the control (i.e. message that will be displayed in the alert) and then when the user clicks on the image button, have the radalert display the message that was set in the property.

Any thoughts?

Hi Dennis,

You can call the radalert from code behind and pass the property value as alert message. Here is the code that I tried.

CS (in ascx):

    protected void Page_Load(object sender, EventArgs e)
    {
        Name = "Telerik";
    }
    private string _Name;
    public string Name
    {
        get
        {
            return _Name;
        }
        set
        {
            _Name = value;
        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string radalertscript = "<script language='javascript'>function f(){radalert('" + Name + "', 330, 210); Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
        Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radalertscript);
    }
    protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
    {
        string radalertscript = "<script language='javascript'>function f(){radalert('" + Name + "', 330, 210); Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
        Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radalertscript);
    }

Thanks,
Princy.
