Error with deleting button

May 04, 2012 05:43 PM|LINK

Hi,

In my grid view, this code is working well but deleting without confirmation

<asp:CommandField ShowDeleteButton="True" ButtonType="Button"
                          DeleteText="Supprimer" />

hwever this code give me an error

 <asp:TemplateField>
<ItemTemplate>  
 <asp:Button ID="YesButton" runat="server" Text="Supprimer"  OnClientClick="javascript:return confirm('Etes vous sûr ?');" CommandName="Delete" />
   </ItemTemplate>  
</asp:TemplateField>

I'm getting the following error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Can you help me PLZ?

Well, do you have this directive: <%@ Page EnableEventValidation="true" %>

at the top of your aspx page? If not, put it in and try it again.

<asp:CommandField ShowDeleteButton="True" ButtonType="Button"
                          DeleteText="Supprimer" />

Replace the above lines in your aspx page with this..

 <asp:TemplateField>
 <ItemTemplate >                              
 <asp:Button ID="Button1" runat="server" CommandName="Delete" Text="Delete"
  OnClientClick="return confirm('Are you sure you want to delete this data Row?')" />
 </ItemTemplate>                        
 </asp:TemplateField>

Kindly mark this post as "Answer", if it helped you.

(Talk less..Work more)

Ok, I'm officially intrigued. Can you post both the aspx and code behind pages? There could be something else interferring.

You have two delete buttons which could be the problem:

<asp:BoundField DataField="N_série" HeaderText="N_série"
                          SortExpression="N_série" />
 
                          <asp:CommandField ShowDeleteButton="True" ButtonType="Button"
                          DeleteText="Supprimer" />
                           <asp:TemplateField>
<ItemTemplate>
 <asp:Button ID="YesButton" runat="server" Text="Supprimer"  OnClientClick="javascript:return confirm('Etes vous sûr ?');" CommandName="Delete" />
   </ItemTemplate>
</asp:TemplateField>
 
 <asp:TemplateField>
 <ItemTemplate >
 <asp:Button ID="Button1" runat="server" CommandName="Delete" Text="Delete"
  OnClientClick="return confirm('Are you sure you want to delete this data Row?')" />
 </ItemTemplate>
 </asp:TemplateField>

No I had the problem, before having 2 buttons (with only one button) , I just added several buttons of delete to try to see if the problem persists

I get the same error when trying to add a button to update or delete, but when using the "
```
<asp:CommandField ShowDeleteButton or <asp:CommandField ShowSelectButton or <asp:CommandField ShowupdateButto
```
```
) it works
```
