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.

[Solved] Linkbutton In Grid OnClick event

OK, I have a radgrid with a GridButtonColumn (below)

<telerik:RadGrid ID="grdOrderedItems" OnNeedDataSource="OrdItem_NeedDataSource"

OnItemDataBound="OrdItemDatabound" runat="server" AutoGenerateColumns="False" AllowPaging="False">

<ClientSettings>

<Scrolling AllowScroll="True" ScrollHeight="250px" UseStaticHeaders="True"></Scrolling>

</ClientSettings>

<MasterTableView NoMasterRecordsText="You have no ordered items att his time.">

<Columns>

<telerik:GridBoundColumn HeaderText="Order Number" DataField="OrderNumber"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Item Number" DataField="ItemNumber"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Item Name" DataField="ItemName"></telerik:GridBoundColumn>

<telerik:GridButtonColumn HeaderText="View Custom Print" UniqueName="btnView" DataTextField="CustomID"></telerik:GridButtonColumn>

<telerik:GridBoundColumn HeaderText="Custom ID" DataField="CustomID" Visible="False"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Friendly Name" DataField="FriendlyName" Visible="False"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Ordered By" DataField="OrderedBy"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Shipped?" DataField="Shipped"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

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.

[Solved] CustomValidator client function fires multiple times after postback.

After the postback of the RadGrid in one update panel, the custom validator in another panel fires numerous times. The more postbacks you do on the RadGrid, the more times the validator will fire.

Here is the sample code. Watch "Count: 0" before a postback and after selecting a row or two in the RadGrid.

Before postback, the validator runs once every time you change the textbox or press the button. After selecting a couple of grid rows, it will fire multiple times....

You can execute the validator by changing the text in the text box to anything other than "hello"...

Move the validator out of the ajaxified table and it works as expected...

How can I have the custom validator inside the ajaxified table act properly after postback?
