Scripts could not see control ToolkitScriptManager

Jan 16, 2014 02:20 PM|tinac99|LINK

Hi,

My server-side scripts and client-side scripts are unable to see the object ToolkitScriptManager ID="ScriptManager1".

Please see my code below:

Server-side:

if (this.Page.FindControl("ScriptManager1") != null)

{

((ScriptManager)this.Page.FindControl("ScriptManager1")).RegisterPostBackControl(btn);

}

Client-Side:

<asp:ToolkitScriptManager ID="ScriptManager1" runat="server" CombineScripts="false" EnablePartialRendering="true" LoadScriptsBeforeUI="true" >

</asp:ToolkitScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" runat="server" >

<ContentTemplate>

<asp:Panel ID="Panel3" runat="server" Visible="false">

<asp:HiddenField ID="HiddenField1" runat="server" />

<asp:TabContainer ID="TabContainer1" runat="server" CssClass="Tab" OnActiveTabChanged="TabContainer1_OnActiveTabChanged" AutoPostBack="true" >

<asp:TabPanel runat="server" ID="TabPanel1" HeaderText=" Page1 ">

<ContentTemplate>

<asp:Panel ID="Panel4" runat="server" ScrollBars="Vertical" Height="500px" >

<uc1:ucPageA ID="ucPage1" runat="server" />

</asp:Panel>

</ContentTemplate>

</asp:TabPanel>

<asp:TabPanel runat="server" ID="TabPanel2" HeaderText="Page2" BackColor="#99CCFF" >

<ContentTemplate>

<asp:Panel ID="Panel5" runat="server" ScrollBars="Vertical" Height="500px" >

<asp:HiddenField ID="HiddenField3" runat="server" />

<uc2:ucPageB ID="ucPage2" runat="server" Visible="false" />

</asp:Panel>

</ContentTemplate>

</asp:TabPanel>

<asp:TabPanel runat="server" ID="TabPanel3" HeaderText="Page3" >

<ContentTemplate>

<asp:Panel ID="Panel6" runat="server" ScrollBars="Vertical" Height="500px">

<asp:HiddenField ID="HiddenField4" runat="server"/>

<uc2:ucPage2 ID="UcPage3" runat="server" Visible="false" />

</asp:Panel>

</asp:TabContainer>

</asp:Panel>

</ContentTemplate>

</asp:UpdatePanel>

<script type="text/javascript">

Sys.Extended.UI.TabPanel.prototype._header_onclick =function(e) {

if (confirm("Yes?")) {

this.raiseClick();

this.get_owner().set_activeTab(this);}

};

</script>

In the server-side, the "FindControl" function is always returning null.

In the client-side, I always run into this error: "Mircorsoft JScript runtime error: Sys.Extended.UI.TabPanel.prototype is null or not an object. " Research states to set the combinescripts property of the ajaxtoolkit to false, which I did.

Also, the line Sys.Extended.UI.TabPanel is all black on my page, unlike some the samples I've seen is blue. Maybe this is a clue.

I'm using VS 2010, .Net Framework 4.5, AjaxControlToolkit.Binary.NET4.

Please advise.

Thanks,

The client-side scripts must be regeistered in the ToolkitScriptmanager. Try like in the example below:

<asp:ToolkitScriptManager ID="SiteToolkitScriptManager" runat="server">
  <Scripts>
    <asp:ScriptReference NotifyScriptLoaded="false" ScriptMode="Auto" Path="~/Scripts/jquery-1.9.1.js" />
  </Scripts>
</asp:ToolkitScriptManager>

Have you checked the path to the script is correct?

I noticed you are using VS2010 with 4.5 framework. VS2010 is 4.0 framework or lower.

Try this

((ToolkitScriptManager)this.Page.FindControl("ScriptManager1")).RegisterPostBackControl(btn);

Or AjaxControlToolkit.ToolkitScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(btn);

Hi,

In the code that you have provided the TabPanel3 is missing the following:
```
</ContentTemplate>
</asp:TabPanel>
```
maybe that is the problem?

Best regards

@valuja: Thanks for your reply. Sorry, what I posted initially was just a snippet of the whole code. I left out that part but was actually in the code.

@krutovdl: I have both VS2010 and VS 2012 on my machine. For some reason, because of connection to TFS, VS 2012 is harder to get around so I'm just using VS2010. When I click on the Help->About-> it says Microsoft .NET Framework, Ver 4.5 SP1Rel

this is rewrite in response to krutovdl's reply:

<asp:ToolkitScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" CombineScripts="false" LoadScriptsBeforeUI="true" >

<Scripts>

<asp:ScriptReference NotifyScriptLoaded="false" ScriptMode="Auto" Path="js/tabBehavior.js" />

</Scripts>

</asp:ToolkitScriptManager>

tabBehavior.js

document.write("hello1");

Sys.Extended.UI.TabPanel.prototype.header_onclick =function(e) {

document.write("hello2");

this.raiseClick();

if (isValidated()) {

// add this additional code line to do validation

document.write("hello6 - isValidated()");

this.get_owner().set_activeTab(this);

}

};

function isValidated() {

document.write("hello3 - validated");

return false;

}

On the initial load of the page, on debug mode, it displays: Sys.Extended.UI is null or not an object. When I switch tabs, it always "hello1".

Try chaging
```
<asp:ScriptReference NotifyScriptLoaded="false" ScriptMode="Auto" Path="js/tabBehavior.js" />
```
to something like:
```
<asp:ScriptReference NotifyScriptLoaded="false" ScriptMode="Auto" Path="~/scripts/js/tabBehavior.js" />
```
Basically provide a full path to the js file.
