Problem in execution of Client script and server method while a single click.

[Shanthini Ganesh]

hi all. in my shopping cart project , i tested with two buttons, one for execution of client click and another for exection server method. these two buttons are as follows..
<input id="addbutton" type="button" value="Add Products" onclick='addToBasket(<%#DataBinder.Eval(Container. DataItem, "ProductNo")%>)' />
//this button used for execution for javascript method...
<asp:Button ID="Button1" runat="server" Commandname='<%#DataBinder.Eval(Container.DataItem , "ProductNo") %> ' OnCommand="FilterData" Text="Add to Cart" /></br>
// this button used for execution of serverside method..


Now i need to combine both button functons in a single button..(ie) when i click the button it execute both javascript function and also server side code..
is it possible.. any one know how to do this..
i am waiting for your reply..

thank you...

It is definitely possible:

<asp:Button ID="btnDo" OnClientClick="return addToBasket()" CommandName="" OnClick="btnDo_Click" runat="server" />
 

This will call the javascript method addToBasket, and assuming it doesn't return false, it will then do the server postback and call btnDo_Click

Hi. Thank u for ur Reply..
I tried ur code..
<asp:Button ID="Button1" Text="add to cart" OnClientClick='return addToBasket(<%#DataBinder.Eval(Container.DataItem, "ProductNo")%>)' OnCommand="FilterData" CommandName='<%#DataBinder.Eval(Container.DataItem , "ProductNo")%>' runat="server" />

hi.
just try this way.
in aspx.cs page add
buttonserver.attributes.add("onclick","javascriptf unction()")

inline code
javascript function()
{
if()
{ coding
return true; //go to server
}
else
{ coding
return false; // don't go to server
}
}

The code is valid as I've run it myself. View the HTML output of the aspx page and ensure the button has the onclick attribute added and the js function name is valid, etc.
