[Solved] Javascript error when using RadTreeView in invisible detailsview field

Hello.

I'm using a asp:DetailsView to show some data. This data has some attached material that I display in a RadTreeView, using a TemplateField. Sometimes, however, this field should not be visible, so I set its "Visible" property to false. If I do that, I get a javascript error here:

The error occurs on the line marked with red, because the variable "_23a" is null. As said, this error only occurs if the TemplateField in the DetailsView is set to Visible=false. If set to true, there's no problem. A solution would be much appreciated, as being able to hide fields in a DetailsView seems like something that shouldn't be prohibited.

EDIT: For some reason, when setting the color on the row in the code block, it jumped out of its box (above) and ended up at the very bottom of my post. This seems a bug too, if you ask me. ;-)

...

Telerik.Web.UI.RadTreeView._preInitialize=function(_239,_23a){
var _23b=$get(_239);
_23b.scrollTop=_23a;
if(Telerik.Web.UI.RadTreeView._isRtl(_23b)){
Telerik.Web.UI.RadTreeView._initializeRtl(_23b);
}
};

Error when trying to get Control ID

Newbie, I am trying the examples, and get error from VS2008:

Javascript:

var panel = $find( "<%=RadPanelBar1.ClientID %>" );

Error:

The Controls collection cannot be modified because the control contains codeblocks (i.e. <% ... %>).

How do I fix this? ($find( "RadPanelBar1" ) is OK)

--------------------------------------------------------------------------------------------------------

Here is my partial web page:

<telerik:RadPanelBar ID="RadPanelBar1">

<Items>

<telerik:RadPanelItem>

<Items>

<telerik:RadPanelItem>

<telerik:RadTreeView ID="RadTreeView1" runat="server">

</telerik:RadTreeView>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

....

How do I get to get to RadTreeView1 to manipulate the tree?

Thanks.

ClientEvents: OnCommand issue

Hi,

I addedcode in the Grid <ClientEvents> to call a javascript function. The javascript function is as below:
function RaiseCommand(sender,args)
{

    if(args.get_commandName()=='Page' || args.get_commandName()=='Sort')
    {
        if('<%= grdOrders.MasterTableView.IsItemInserted %>' == 'True')
        {
            if(confirm("Some of the data entered may be lost. Do you want to continue?"))
            {
                 args.set_cancel(false);
            }
            else
            {
                args.set_cancel(true);
            }
        }
    }
}

As seen from the above, this is to alert the user that a data will be lost in the InsertItem if the page is changed or sorted.

The issue is that, this function is called correctly and also the alert is displayed.
But let's say that there are just 2 pages in the grid and in the insertitem is on page 2 and I chose to navigate to page 1. When I click on 'Prev' icon the confirm message comes up and I cancel it i.e. choose not to navigate. Now when I want to navigate to Page 1, the pager doesnt work. The page navigates to page 1 when I click on 'Next' icon and not on 'Prev' icon. This is incorrect. Also the footer message is getting changed to Page 1 of 2 even in the event of I cancelling the Command.

Any pointers?

"Rad*** is not a known element"

Just a shared tip, that may be handy to someone doing a search.

We had trouble getting the Rad controls to offer intellsense in the ASPX source code environment. Site built fine, all worked fine, just no intellisense.

We had installed the Telerik.Web.UI into the GAC and had the following entry in our web.config

    
               <system.web> 
        
                    <pages > 
        
                        <controls> 
        
                            <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" />

which was our problem ... it needed to be specific (version, etc) to get intellisense:

    
               <system.web> 
        
                    <pages > 
        
                        <controls> 
        
                            <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2008.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />

If we've made a mistake with this observation, we'd welcome the comment.

Thanks.

Open RADWindow after PostBack

Hi,

I wanted to open a radwindow after my button is clicked based on certain condition from server side.
For that I have written

    Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
        'Me.ClientScript.RegisterStartupScript(Me.GetType, "startup", "radopen('google.com');", True)
        Me.ClientScript.RegisterClientScriptBlock(Me.GetType, "startup", "radopen('google.com');", True)
    End Sub

It is throwing me a javascript error undefined !
Neither RegisterStartupScript nor RegisterClientScriptBlock is working !

after that I have opened my radwindow after 1000 milisecond and it is working fine
means I have written

    <script type="text/javascript">
        function showMatrixWindow()
        {
            radopen('http://google.com');
        }
    </script>

on my aspx page and written

        Me.ClientScript.RegisterStartupScript(Me.GetType, "startup", "setTimeout(showMatrixWindow,1000);"
, True)

Things working fine now but why should I wait my client for even 1second.

I have even tried to bind radopen function when my document is in ready state but there it is also throwing error !

Help me out !

Thanks
