Hello! I hope can help me ..
I need to show a confirmation message before the
Deleting a row, I tried this:

    
            <telerik:RadGrid ID="rgSucursales" runat="server" AllowPaging="True" AllowSorting="True" 
        
                                    GridLines="None" onneeddatasource="rgSucursales_NeedDataSource"  
        
                                    VirtualItemCount="1" onitemcommand="rgSucursales_ItemCommand"  
        
                                    onitemdatabound="rgSucursales_ItemDataBound" > 
        
                                    <PagerStyle FirstPageToolTip="Primera Página" /> 
        
                                    <MasterTableView PageSize="5"> 
        
                                        <Columns>  
        
                                            <telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Editar"  
        
                                                ImageUrl="img/editar.png" Text="Editar Cuenta" UniqueName="column"> 
        
                                            </telerik:GridButtonColumn> 
        
                                            <telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Eliminar"  
        
                                                ImageUrl="img/eliminar.png" Text="Eliminar Cuenta" UniqueName="EliminarColumna"  > 
        
                                            </telerik:GridButtonColumn> 
        
                                        </Columns> 
        
                                    </MasterTableView> 
        
                                    <ClientSettings EnableAlternatingItems="False"> 
        
                                        <Selecting AllowRowSelect="False" /> 
        
                                        <ClientMessages PagerTooltipFormatString="Página &lt;strong&gt;{0}&lt;/strong&gt; de &lt;strong&gt;{1}&lt;/strong&gt;" /> 
        
                                    </ClientSettings> 
        
                                </telerik:RadGrid>

    
            protected void rgSucursales_ItemCommand(object source, GridCommandEventArgs e) 
        
                    { 
        
                        string cmd = e.CommandName.ToString(); 
        
                        if (cmd.Equals("Editar")) 
        
                        {                 
        
                            Session["BANEDIT"] = item["Codigo"].Text; 
        
                            rwSucursales.NavigateUrl = "~/OperCat.aspx"; 
        
                            rwSucursales.Visible = true; 
        
                        } 
        
                        else if (cmd.Equals("Eliminar")) 
        
                        { 
        
                            GridDataItem item = (GridDataItem)e.Item; 
        
                            ImageButton deleteBtn = (ImageButton)item["EliminarColumna"].Controls[0]; 
        
                            deleteBtn.Attributes.Add("OnClick", "if(!confirm('¿Está seguro que desea Realizar la Venta?')){return false;};"); 
        
                            var codigoEliminar = item["Codigo"].Text; 
        
                            if (_dbase.DeleteQuery("Delete From tb where id_Bs=" + codigoEliminar).Equals("Ok")) 
        
                            { 
        
                                //Row deleted 
        
                                                                               "AlertSucess('#effect','¡La Cuenta ha sido eliminada!');", true); 
        
                            } 
        
                            else 
        
                            { 
        
                                //Problem in query 
        
                            } 
        
                        } 
        
                    }

But the problem is that the first time I press the
button deletes the row, when I delete another row
It works and shows me the message.

That way I can show the confirmation message without
do a postback?

Thanks for your help!

Hello Briayan,

A better approach would be to use the ConfirmText property of the GridButtonColumn, for which you would not have to implement custom code and this will not cause a postback! Here's an example:
aspx:

    
            <telerik:GridButtonColumn ButtonType="ImageButton" ConfirmText="¿Está seguro que desea Realizar la Venta?" 
        
             CommandName="Eliminar" ImageUrl="Images/UnSelected.gif" Text="Eliminar Cuenta" UniqueName="EliminarColumna">  
        
            </telerik:GridButtonColumn>

Hope this helps..
Princy.
