Adding A JavaScript Confirmation Prompt To A Delete Command Button In An ASP.NET Grid View?

So I have an ASP.NET grid view:

Solution 1:

You could always use a TemplateField rather than the CommandField.

<asp:TemplateField>
  <ItemTemplate>
    <asp:Button name="btnDelete" commandName="Delete" OnClientClick="return confirm('Delete 
this Item');" Text="Delete" runat="server" />
    <asp:Button name="btnEdit" commandName="Edit" Text="Edit" runat="server" />
  </ItemTemplate>
</asp:TemplateField>

Solution 2:

When I've done this I've used a Template Field with the ConfirmButtonExtender from the Ajax Control Toolkit.

<asp:TemplateField>
   <ItemTemplate>   
       <asp:Button name="DeleteButton" commandName="Delete" Text="Delete" runat="server" />   
       <ajaxToolkit:ConfirmButtonExtender TargetControlId="DeleteButton" ConfirmText="Delete this entry?" />
   </ItemTemplate>   
</asp:TemplateField>  

Solution 3:

This is a javascript for delete confirmation.

 function not_check1()
            {
              var where_to1= confirm("Do you really want to delete this record??");

                                    if (where_to1 == true)
                                        {
                                            return true;
                                        }
                                    else
                                        {
                                            return false;
                                        }
           }

This is a gridview field from where you call the javascript.

 <asp:TemplateColumn ItemStyle-Width="20" >
<ItemTemplate>
 <asp:ImageButton ID="ib_delete" runat="server" ImageUrl="~/image/images.jpg" commandName="Delete"  OnClientClick="return not_check1();" ImageAlign="Middle"/></ItemTemplate>

</asp:TemplateColumn>

Solution 4:

In RowDataBound add -

LinkButton objDelete = e.Row.Cells[0].Controls[0] as LinkButton;
objDelete.Attributes.Add("onclick", "javascript:return confirm('Do you want to delete this item?');");
