Asked On March 14, 2008 12:02 AM UTC

Hello,

So far, we have been using client side Javascript to call a callback panel. For. _sfCallbackPanel1.callback('action:save');
_sfCallbackPanel2.callback('action:display');

Now I want to use the mutiplexer to call these two panels.
_sfCallbackMultiplexer1.callback('bothpanels');

In the code behind event for the multiplexer, how would I pass arguments to panel1 ("action:save") and for panel2 ("action:display") ?

Thanks.

Just to clarify further, I am looking to use the multiplexer to call other callback panels that also takes arguments. How would I accomplish this? There isn't documentation on your web site for it.

Hi Ivan,

Thanks for posting your query to us.

You can call the callback panel in the callback multiplexer event as mentioned in the code below:


protected void CallbackMultiplexer1_Callback(object sender, Syncfusion.Web.UI.WebControls.Shared.CallbackEventArgs e)
{
char[] splitter = {':'};
string[] arr = e.CallbackArgument.Split(splitter);
Callbackpan1(arr[0], arr[2]);
Callbackpan2(arr[1], arr[2]);
}
public void Callbackpan1(string save,string val)
{
int eval = Convert.ToInt32(val);
switch (save)
{
case "save":
CallbackPanel1.BackColor = GetRandomBackColor();
CallbackMultiplexer1.ControlsToRefresh.Add(CallbackPanel1);
break;
case "any":
this.lbl1.Text = "any";
break;
}
}
public void Callbackpan2(string view, string val)
{
int eval = Convert.ToInt32(val);
switch (view)
{
case "view":
CallbackPanel2.BackColor = GetRandomBackColor();

CallbackMultiplexer1.ControlsToRefresh.Add(CallbackPanel2);
break;
case "any":
this.lbl1.Text = "any";
break;
}
}



Please refer the sample in the link below which illustrates the above:

Please try running the above sample and let me know if this helps.
