RadButton Target property not working in OnClick event

[SUBBU]

Hi,
We have a RadButton with Target property set to "_blank".  In the OnClick method we have Response.Redirect("www.google.com").

But the requested url is not opening in new window. Any suggestion is appreciated. Thanks in advance.

Hello,

The Target property of the RadButton has a meaning in the context of ButtonType="LinkButton", along with the NavigateUrl property. For example:

<telerik:RadButton ID="RadButton1" runat="server" Text="Click" NavigateUrl="http://www.google.com"
    ButtonType="LinkButton" Target="_blank" />

When you click on the RadButton the google URL will be opened in a new tab. The Response.Redirect() method, however, is not an embedded method of the RadButton but part of ASP.NET and that is why it redirects the target url to the current tab.

More information on using link buttons is avilable here and here.

Hi Danail,
Thanks for your response. Is there any other way that I can open a link in a new/active window(this will be decided in the Page_Load) along with OnClick event using any of the telerik components? We cant use asp components because, in case of hyperlink we dont have OnClick property and in case of Link Button we dont have target property.

Hello,

I am not sure about your actual scenario, so I can suggest you try one of the following approaches:

• Either override the properties of the RadButton that are set in the markup with the desired ones on the server, for example on Page_Load:

ASPX:

<telerik:RadButton runat="server" ID="RadButton1" ButtonType="LinkButton" Text="Click"
    NavigateUrl="http://www.bing.com" Target="_top">
</telerik:RadButton>

C#:

protected void Page_Load(object sender, EventArgs e)
{
    RadButton1.NavigateUrl = "http://www.telerik.com";
    RadButton1.Target = "_blank";
}

where the highlighted properties override the ones set declaratively.

• OR register a startup script that opens a new window with the desired URL, when the server-side OnClick event is triggered. For example:

ASPX:

<telerik:RadButton runat="server" ID="RadButton1" Text="Click" OnClick="OnClick1">
</telerik:RadButton>

C#:

protected void OnClick1(object sender, EventArgs e)
{
    string openURL = "<script language='javascript'>function f() { window.open('http://www.telerik.com/','_blank'); Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
    Page.ClientScript.RegisterStartupScript(this.GetType(), "openURL", openURL);
}

More information on executing JavaScript function on the server-side is available in this help article.
