All,

I have a delete button inside a RadAjaxPanel:

<asp:Button id="btnDelete" Text="Delete" OnClientClick="return confirm('Are you sure you want delete this?');" runat="server"/>

The js popup is working, but it is not running the server-side click event attached to button.  Take away the OnClientClick, the server-side event runs fine.

What am I doing wrong?

Cheers,
Dave

Hello David,

Please try modifying your code as below:

<asp:Button id="btnDelete" Text="Delete" runat="server"/  
   OnClientClick="if(!confirm('Are you sure you want delete this?')) return false;"/>

Hi,

I would like to translate this message: 'Are you sure you want to delete this?' in the languages my site uses. So could you tell me how can I modify the following statement using Resources but only for the question and not for the whole string.

OnClientClick="if(!confirm('Are you sure you want delete this?')) return false;"

 
 Thanksss,
Andreas.

Hi Andreas,

In this case you could assign the button OnClientClick property server side, for instance as below:

protected viod Page_Load(object, sender, EventArgs e)     
{     
    string deleteMessage = "";     
    //retrieve the delere message from the Resource file     
    btnDelete.OnClientClick = "if(!confirm('" + delteMessage + "')) return false;";     
}   

I hope this helps.

All the best,
Iana

Hello

I'm using this approach in the aspx file:
 OnClientClick=<%# String.Format("if(!confirm('{0}'))return false;", Resources.GlobalRes.btnDeleteSelected_ConfirmText)%>

It works when you do a DataBind() in the code behind eg. in page_load.

Hi all,
    1. Here we have a function The 'ConfirmDelete()' which is executed each time a click event occurs on the page.
2. Then we use a logic that to find which element was clicked on i.s we append a word 'DELETE' to the ID of the control.
3.And finally check if the clicked element having ID is 'DELETED' , then the javascript function will be execute to ask the user about his/her confirmation.
 
JavaScript code:
 
 function ConfirmDelete(e) 
{    
var targ;

if (!e)
{   
var e = window.event;
}
targ = (e.target) ? e.target : e.srcElement;

if (targ.nodeType == 3) 
{
targ = targ.parentNode;
}

if (targ.id.toLowerCase().indexOf("delete") >= 0) 
{        
return confirm("Do you want to delete this item?");
}
routeEvent(e);
}  
document.onclick = ConfirmDelete;
 
aspx  code:

<asp:GridView RunAt="server" ID="gvTest" DataSourceID="SqlDataSource1">
<Columns>       
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" 
ID="DeleteMe" Text="Delete" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
 Hope this was helpful.

<asp:Button id="btnDelete" Text="Delete" runat="server"/  
   OnClientClick="if(!confirm('Are you sure you want delete this?')) return false;"/> 

this worked for me, my page is surrounded by radajaxpanel with radloading panel & also i have server side onclick event for a button.

The above one worked for me rather than using btn.Attributes.Add("OnClick","return confirm();"); It invokes the condifrm prompt and after receiving the request it triggers the server side code for that button.

Hello, I try this scenario but a little bit different, I want to the confirm window looks as telerik radconfirm. I change the code loke this:
<asp:Button ID="btnDelete" runat="server"="if(!radconfirm('Are you sure you want delete this?')) return false;" Text="DELETE"    />

The radconfirm shows but disappear matters of a blink of the eye.  I don't know why. Any thoughts? my version is 2010.1.415.35

Thanks for the reply. The dialog works but when I press the Ok button not fire the btnDelete_Click
event

aspx
<asp:Button ID="btnDelete" Text="Delete" runat="server" OnClientClick="ShowDialog(this); return false;" OnClick="btnDelete_Click"/>

jscript
function ShowDialog(btn) {
    radconfirm("are you sure you want to delete this?");

c#
protected void btnDelete_Click(object sender, EventArgs e)
       {
          DeleteRecord()
       }

function OnClientClicked(button, args)
{
    if (window.confirm("Do you want to do this postback?"))
    {
        button.set_autoPostBack(true);
    }
    else
    {
        button.set_autoPostBack(false);
    }
}

You can use the function above, and 
OnClientClick="ShowDialog(this); return false;" 
should be
OnClientClicked="OnClientClicked"

Thanks for the reply, do all respect, this workaround does not work. onClientClicked is not an event for asp button or maybe I dont understand what you can achieve with this solution.

Hi Elias,

Actually Ed was probably referring to the OnClientClicked event of the RadButton. In attachments you can find a runnable sample which demonstrates a possible implementation of the described scenario.
