                </telerik:RadToolBarButton>

its print a message 'sssss' but its printing 2 times I disabled postback by choice postback="false" , but in this case when I pressing in this button nothing happened.

Hi eyadmn73,

I tried your code and could not reproduce that error.

Is there any other place that you set to print the "sssss" content in the message box?

You could try below code that I used to see if you still have the problem.

What I can suggest is to comment other codes and just focus on this part.

If the problem disappears, you could be confirmed that the code is correct and there might be other places cause this unexpected error.

.aspx :

<form id="form1" runat="server">
        <div>
            <telerik:RadAjaxPanel runat="server">
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server" />
                <telerik:RadToolBar ID="m_oOverviewToolbar" runat="server" Width="100%" EnableRoundedCorners="True"
                    EnableShadows="True" OnButtonClick="m_oOverviewToolbar_ButtonClick">
                    <Items>
                        <telerik:RadToolBarButton runat="server" Text="OpenRadWindow" CommandName="Edit">
                        </telerik:RadToolBarButton>
                        <telerik:RadToolBarButton ID="i1" runat="server" CommandName="View" Text="ShowMsg" PostBack="true">
                        </telerik:RadToolBarButton>
                    </Items>
                </telerik:RadToolBar>
            </telerik:RadAjaxPanel>
        </div>
    </form>

Code behind:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub


    Protected Sub m_oOverviewToolbar_ButtonClick(sender As Object, e As RadToolBarEventArgs) Handles m_oOverviewToolbar.ButtonClick
        Dim oBtn As RadToolBarButton = e.Item
        If (oBtn.CommandName = "Edit") Then


        ElseIf (oBtn.CommandName = "View") Then
            MsgBox("sssss")
        End If

    End Sub

Result:

Best regards,

Sean
