Hello All,
In my ASP.Net application, i am showing a confirmation box using javascript whenever user intends to delete something.
I have written this code in aspx file

function confirmation()
{
if(confirm("Are you sure?")==true)
return true;
else
return false;
}

Then on Page_Load of my codebehind, i am using this:

btnDelete.Attributes.Add("onclick", "return confirmation();")

It is working fine, if user click ok record is deleting and vice versa.

But when i am trying to write same thing for my GridView delete link its not working, i am writting this:

GridView1.Attributes.Add("OnRowDeleting", "return confirmation();");

Can anybody help me? why its not working for GridView_RowDeleting method?

Thanks,
Nagendra.

This is messy as hell. Why not just return (confirm("Are you sure?")) ? Why not tell them what they are to be sure if, in case they don't realise what they pushed ?

I'd guess that it's because you're trying to hook up to a code behind event, not an actual client side event. You could start by reading on the difference between the client and server.

Thanks, i implemented what u mentioned(used just confirm & displaying proper msg). Smile | :)

I also understand that RowDeleting is server side event and onclick is client side.
But i want this functionality to work for GridView too, what can i do?

try to add itemtemplate in gridview and do it

<ItemTemplate>

                       <asp:LinkButton ID="Delete" CommandName="Delete"
                       OnClientClick="return confirm('Are you sure you wish to delete this item?')"
                       CausesValidation="false"
                        runat="server" Text="Delete" ></asp:LinkButton>
                   </ItemTemplate>

The same thing will work here. actually you are not adding it at correct place. First of all, u are adding the attribute to Grid view. In fact when u wanna delete any item then i m sure u have placed some control in each row on clicking of that , that particular item will be deleted.

So if it is a LinkButton/Button in ItemTemplate then you can add the attribute to it onRowDataBound Event or RowCreated Event or OnClientClick Property itself.

<asp:TemplateField HeaderText="Delete" >
       <ItemTemplate>
             <asp:ImageButton ID="imgbtnDelete" ImageUrl="~/images/delete.jpg" OnClientClick="return confirm('Are you sure you want to delete it ?');"
                                                                            CommandArgument='<%# Eval("UserId") %>' CommandName="DeleteUser" runat="server" />
             </ItemTemplate>
</asp:TemplateField>

ImageButton btn = (ImageButton)(e.Row.FindControl("imgbtnDelete"));
btn.Attributes.Add("OnClientClick","funcationToBecalled();")

Fix your deployment. What else can we say ? Work out what is different between the server and local, and fix it. And when you want help, try to define things like 'not working'.
