Hi guys,
I want to use ASP.NET LinkButton with JavaSript,

i am using Client CallBack without postback,

my javascript is:

<<pre lang="xml">script type="text/javascript">
function ReceiveBikeColor(colorFile)
{
    // any code here
}

<pre lang="cs">public partial class About : System.Web.UI.Page, ICallbackEventHandler
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string cbRef = ClientScript.GetCallbackEventReference(this, "arg", "ReceiveBikeColor", "context");
        string cbScript = "function GetBikeColor(arg, context) {" + cbRef + "; }";
        ClientScript.RegisterClientScriptBlock(this.GetType(), "GetBikeColor", cbScript, true);
    }

    public string GetCallbackResult()
    {
        //////////
    }
    public void RaiseCallbackEvent(string eventArgument)
    {
        ///////
    }
}

but when assign onclick attribute to Javascript method like that:

<asp:LinkButton id="lbtnAddToFavorites" runat="server"  OnClick="GetBikeColor()" >Add to favorites</asp:LinkButton>

it tell me that:

Error 'ASP.specifictopic_aspx' does not contain a definition for 'GetBikeColor'

and when use OnClientClick attribute it casue Postpack

<asp:LinkButton id="lbtnAddToFavorites" runat="server"  OnClientClick="GetBikeColor()" >Add to favorites</asp:LinkButton>

You should check the option 'Display a notification about every script error' if you're using Internet Explorer, just in case.

Are you sure you declared the javascript function GetBikeColor?

I tried to reproduce, and had no problems.

Solution 1

If you're trying to call a js function when someone clicks the LinkButton, OnClientClick is the way to go.

Make sure you defined the function GetBikeColor and that it's accessible.

LinkButton.OnClientClick Property [^]

LinkButton.OnClick Method [^]

Hope this helps!

try that way

function GetBikeColor()
{
//Some Implementation
return false;
}

<asp:LinkButton id="lbtnAddToFavorites" runat="server"  OnClientClick="return GetBikeColor();" >Add to favorites</asp:LinkButton>
