i have a regular asp:button. I am working in .Net 3.5. I've tried adding a js confirm to the button with the OnClientClick attribute as well as adding in code-behind and the result is the same. No matter what the user clicks in the confirm pop-up the form will not submit??
BtnDeleteSelected.Attributes.Add("onclick", "return confirm('Are you sure you want to delete?');");
The confirm dialog appears and if i select "OK" it still does not submit.. Any ideas? thanks.

Reset to default 5That's because you should not be returning in all cases. If you view the source of the page and look for the button markup, you are likely to see this...
onclick="return confirm('Ok?'); __doPostback();"
The __doPostback invocation is inserted automatically by the ASP.NET framework in some cases. Since you return immediately regardless of the result of confirm
, the postback never fires. The ultimate solution would be to not to set the onclick attribute, but instead use an unobtrusive approach. However, if there is pressing reason to control this on the server-side via onclick, you can use a simple if
statement and only return when they press "Cancel"...
string js = "if(!confirm('Are you sure you want to delete?')) return false;";
BtnDeleteSelected.Attributes.Add("onclick", js);
I had this problem too. I was using adding the client side javascript in the OnItemCreated
code of a datagrid like this:
myTableCell = e.Item.Cells(iDeleteColumnNumber) 'Delete Button Column
myDeleteButton = myTableCell.Controls(1)
If myDeleteButton.UniqueID = "lbtnDelete" Then
myDeleteButton.Attributes.Add("onclick", "if(!confirm('OK to Delete?'))return false;")
End If
For some reason that didn't work. I then moved the JavaScript to the <asp:linkbutton>
in the design view like this:
<asp:LinkButton id="lbtnDelete" runat="server" CssClass="link-text" Text="<img border=0 src=../images/icons/icon-delete.gif alt=Delete>"
CommandName="Delete" CausesValidation="false" OnClientClick="if(!confirm('OK to Delete?'))return false;"></asp:LinkButton>
And that worked for me.
Do you have to return TRUE if validation passes? Meaning, if confirm() returns false I don't think the form will submit.
Your code looks OK on the surface. Do you have any validators that might be preventing it being submitted? Try adding BtnDeleteSelected.CausesValidation = false
to prevent the delete button calling any client-side validators.
Please try calling doPostBack function ;)
I mean:
BtnDeleteSelected.Attributes.Add("onclick", "CheckConfirm();");
<script language="javascript">
function CheckConfirm()
{
if ( confirm('Are you sure you want to delete?') )
__doPostBack('BtnDeleteSelected','');
else
return false;
return true;
}
</script>
Hope that helps,
