RadGrid Finding Problem in Underlying Control

Hi,

I am using radgrid and in itemtempalte I have a dropdownlist and a label control. OnItemDatabound event I am passing the ids of dropdownlist and a label control to a javascript function. The functions finds the client ids of the dropdownlist and a label control but when I use document.getElementbyId for label control it gives me null.

Any help would be really appreciated.

Thanks

function OnSelectedIndexChange(ddlTopic, lblTopic) {

alert(ddlTopic);

alert(lblTopic);

var ddl = document.getElementById(ddlTopic);

var lbl = document.getElementById(lblTopic); // The problem occurs here

alert(lbl);

ddl.style.display = "none";

}

RadMenu with WCF and RadGrid

Hi,

I need a help regarding the Read menu with WCF and radgrid.

I have a red grid with template column. In Template column there is a RedMenu. That rad menu items will be desided (when expand get from WCF service) . I followed the link below. It worked well.

http://www.telerik.com/help/aspnet-ajax/menu-items-wcf-service.html.

But in my case I need to pass data from the row in DataGrid to WCF service. For example will assume grid containes Order details and column with "Order Number". I need to pass the "Order Number" to the WCF method as done in above sample.

sample has done this using js method as follows.

function OnClientItemPopulatingHandler(sender, e) 
    {        
        var context = e.get_context();
        //using jQuery to get the checked item and pass it to the server        
        context["ProductSuite"] = $telerik.$("input[name='rblSuites']:checked").val();
    }

I need to do this as follows

function OnClientItemPopulatingHandler(sender, e) 
    {        
        var context = e.get_context();
        //using jQuery to get the checked item and pass it to the server        
        context["OrderNumber"] = GET THE ORDER NUMBER FROM ROW BELONGS TO THE RADMENU.
    }

can anybody help me to resolve this ?

Thank you

Error after publish to IIS

Hi,

I've just published a website I've developed (using Visual Studion 2010 using .NET 4.0) in my IIS Server. I have two pages I'm testing: the Login page which does not contain any Telerik controls and another page to which I am directed after logging in. This second page now contains Telerik controls.

Unfortunately, the page is not rendered at all and I'm getting this error instead.

An unhandled exception occured...
Error Message:	Object reference not set to an instance of an object.
Stack Trace:	at Telerik.Web.UI.ScriptEntrySlot.GetSerializedAssemblyInfo(ScriptEntry scriptEntry) at Telerik.Web.UI.ScriptEntryUrlBuilder.TryAddScriptEntry(ScriptEntry scriptEntry) at Telerik.Web.UI.ScriptEntryUrlBuilder.RegisterScriptEntry(ScriptEntry scriptEntry) at System.Web.UI.ScriptManager.RegisterScripts() at System.Web.UI.ScriptManager.OnPagePreRenderComplete(Object sender, EventArgs e) at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Is there something you could suggest that I could check or change?

Close open items when returning to home page

Hi

I am using PanelBar as a 2-level menu, and have set ExpandMode="SingleExpandedItem" PersistStateInCookie="True" and this works as expected.

However, I would like to have the open item close when the user clicks another top level menu item even if the clicked item does NOT have any child items in it.

How can I achieve this behaviour? Can someone help with this?

I need to achieve this because I realize after user testing that it is the user expectation!

Thanks

Clive

Please need help with web.config - Could not load file or assembly 'Telerik.Web.UI

Hi, all.
A bit new to web development but not new to software development.
Web application is using Telerik grid and upload controls. Everything is working as expected on development machine.
How it was deployed on the server: copied everything including bin folder to the server. Telerik.Web.UI.dll is there. File version-2011.1.315.40. Product version -2011.1.315.40.
Checked app pools, frameworks are same for app pool and for web application.
When started on the server I am getting to login screen OK. Login screen is passed to next screen that is using Telerik control and there I am keep getting "Could not load file or assembly 'Telerik.Web.UI, Version=2011.1.315.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The system cannot find the file specified."

Thank you,
Alex.

I want to have an onclick event with a command argument
I kind of have it - but this line
btnView.Attributes.Add("OnClick", "LoadProof(null, null)");
gives me some issues...

protected void OrdItemDatabound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.AlternatingItem || e.Item.ItemType == GridItemType.Item)

{

if (e.Item is GridDataItem)

{

GridDataItem itemValue = (GridDataItem)e.Item;

LinkButton btnView = (LinkButton)itemValue["btnView"].Controls[0];

btnView.Attributes.Add("OnClick", "LoadProof(null, null)");

btnView.CommandArgument = string.Format("return Click('{0}';", itemValue.GetDataKeyValue("CustomID"));

}

I need to fire this block of code:

protected void LoadProof(object sender, EventArgs e)

{

//.... do some stuff

}

But I can't figure out how to call the object and arguments - for the onclick:
btnView.Attributes.Add("OnClick", "LoadProof(null, null)");
Any suggestions? I know, it shouldn't be "null, null" - but I can't use "sender, e" - Visual Studio doesn't like it.
