LoaderException

Hi:
I was getting a LoaderException and I was quite lost, but then I found the

Could not load file or assembly 'Telerik.Web.UI, Version=2010.3.1109.40, Culture=neutral,

PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's

manifest definition does not match the assembly reference. (Exception from HRESULT:

0x80131040)":"Telerik.Web.UI, Version=2010.3.1109.40, Culture=neutral, PublicKeyToken

=121fae78165ba3d4

I figure out that the Telerik.Web.UI.xml and Telerik.Web.UI.dll were different versions. Hope this helps someone.
Phil

Telerik broken when upgraded website from .net 3.5 framework to 4.0

Hello
Our ASP.NET (not MVC) website was running fine using framework 3.5.

We upgraded the .net framework to 4.0 yesterday and we started getting the following javascript errors:
http://local.demo.ca/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a1f68db6e-ab92-4c56-8744-13e09bf43565%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2011.1.413.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3abd09f19b-b595-4ea4-8ab8-449a745bc83c%3a16e4e7cd%3af7645509%3a24ee1bba%3af46195d3%3a19620875%3a874f8ea2%3a490a9d4e%3a58366029%3a39040b5c%3abd8f85e4Failed to load resource: the server responded with a status of 404 (Not Found)

and

Uncaught Error: ASP.NET Ajax client-side framework failed to load.

and

Uncaught ReferenceError: Sys is not defined

How can we fix this?
Do we need to replace the Telerik files in the bin directory to the 4.0 ones?
Do we need to change some settings in the web.config?

When we tried to put the 4.0 dlls in the bin folder we get the following error:

Could not load file or assembly 'Telerik.Web.UI, Version=2011.1.413.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Please advise steps.

Pager does not work with default URL

I am redoing an existing site to use ASP.Net and Telerik controls. The owner has lots of links that rely on the default page in IIS. For example, www.mydomain.com/search/. In the search folder, I replaced index.asp with my new index.aspx. The page comes up no problem. But when the user tries to change pages with the DataPager, the page posts, but does not refresh. If I manually change the URL to www.mydomain.com/search/index.aspx, then the pager behaves properly.

The old manual .asp code would handle this without a problem.

How do I fix this?

Referencing client-side event handlers for a user control

We have wrapped the .Net TreeList control for our application. Once the ASP page is loaded and starts execution, we get on error stating that the ClientSettings.ClientEvents handlers are undefined. We have tried declaring the event handlers in the TreeList declaration of the TreeList in the .ascx file and setting the event handlers at run time in the .ascx.vb file.

We tried registering the client scripts which I don’t like having to place an entire function in a string. We have placed the reference function in the .ascx file and in a separate file which is then included in the outer .aspx file.

We have just upgraded to the latest version last week. I’m not sure what version. From Visual Studio, the Telerik About menu doesn’t display version information, just an advertisement.

What is the proper method of creating a user control with client side event handlers? We found several similar questions posted, but none of the answers appear to work for this version.

Delete Command and Grid Refresh

Hi,

I have a strange issue.

I have a form that has multiple RadGrids. On a few of these Grids I have a Delete Command which would delete that particular row.

When the delete command is called, the appropriate event is fired and the code is executed correctly. The right row gets deleted from the database. However, when the control refreshes, it results in an empty grid. If I refresh the entire page, the grid will show the correct number of rows.

I've used the delete command on many other forms without this issue. and I'm stuck on what could be the cause.

Anyone else had the issue when the Delete Command is fired that the grid displays no rows, even though the database rows are there?

Thanks
JM

White columns w/o controls in edit mode

I'm having a weird problem with some of the RadGrids I'm using. Certain columns appear all in white and without any controls in them when in edit mode. This happens in IE, Chrome, and Firefox (except the column is yellow in Firefox), and I don't understand why.

You can see 2 pics of the grid attached below. One is in read only mode, and the other is in edit mode. Do notice that I am using inplace editing and making all of the rows editable.

Here's the aspx code (I renamed some column and control names).

<telerik:RadGrid ID="radgrid1" AutoGenerateColumns="False" runat="server"

GridLines="None" Skin="Office2007" CellSpacing="0" DataSourceID="radgrid1DataSource"

OnItemInserted="radgrid1_ItemInserted" AllowAutomaticInserts="true"

OnItemDataBound="radgrid1_ItemDataBound" OnItemCommand="radgrid1_ItemCommand"

AllowAutomaticDeletes="true" ValidationSettings-EnableValidation="false">

<MasterTableView DataKeyNames="KeyID" EditMode="InPlace" AllowAutomaticInserts="true"

AllowAutomaticDeletes="true">

<Columns>

<telerik:GridBoundColumn DataField="KeyID" Visible="false" UniqueName="KeyID"

HeaderText="<%$ Resources:GlobalResources, KeyID %>" />

<telerik:GridBoundColumn DataField="ProjectID" Visible="false" UniqueName="ProjectID"

HeaderText="<%$ Resources:GlobalResources, ProjectID %>" />

<telerik:GridBoundColumn DataField="Name" UniqueName="Name"

HeaderText="<%$ Resources:GlobalResources, Name%>" />

<telerik:GridNumericColumn DataField="InitialAmount" NumericType="Number"

DataFormatString="{0:N}" DecimalDigits="2" UniqueName="InitialAmount"

HeaderText="<%$ Resources:GlobalResources, InitialAmount%>" />

<telerik:GridTemplateColumn UniqueName="CurrencyCode" ItemStyle-Width="260px"

HeaderText="<%$ Resources:GlobalResources, CurrencyCode %>">

<ItemTemplate>

<%# DataBinder.Eval(Container.DataItem, "CurrencyCode") %>

</ItemTemplate>

<EditItemTemplate>

<cc:CurrencyDropDownList ID="ddlCurrency" runat="server" IsAlertsVisible="false"

IsLockVisible="false" IsHistoryVisible="false" IsFieldLabelVisible="false" IsReadOnly="false"

IncludeNullValue="false" MyDropDownList-SelectedValue='<%# Bind("CurrencyCode") %>' />

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridCheckBoxColumn DataField="ToDelete" UniqueName="ToDelete" HeaderText="Delete" />

<telerik:GridEditCommandColumn ButtonType="PushButton" InsertText="Confirm" EditText="Edit"

CancelText="Cancel" UniqueName="EditCommandColumn" />

</Columns>

<NoRecordsTemplate>

No Records Found.

</NoRecordsTemplate>

<CommandItemTemplate>

<table cellpadding="5" style="width: 100%">

<tr>

<td align="left">

<asp:LinkButton ID="btnAddNewRecord" runat="server" CommandName="InitInsert">

<img style="border:0px" alt="" src="../Images/add.png" />Add New Record

</asp:LinkButton>

</td>

<td align="right">

<asp:LinkButton ID="btnDeleteSelected" runat="server" CommandName="DeleteSelected"

OnClientClick="javascript:return confirm('Delete all selected records?')">

<img src="../Images/delete.png" alt="" style="border:0px" />Delete Selected

</asp:LinkButton>

</td>

</tr>

</table>

</CommandItemTemplate>

</MasterTableView>

</telerik:RadGrid>

Here's some of the only relevant C# code (i.e. relevant to the ToDelete column and the grid itself):

protected void Page_Load(object sender, EventArgs e)

{

if (this.IsInEditMode)

{

for (int i = 0; i < this.radgrid1.PageSize; i++)

{

this.radgrid1.EditIndexes.Add(i);

}

this.radgrid1.Columns.FindByUniqueName("ToDelete").Visible = true;

this.radgrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Bottom;

}

else

{

this.radgrid1.Columns.FindByUniqueName("ToDelete").Visible = false;

this.radgrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;

}

protected void radgrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e != null)

{

if (e.Item is GridDataItem && !e.Item.IsInEditMode)

{

GridDataItem item = e.Item as GridDataItem;

Button editButton = (Button)item.Controls[item.Controls.Count - 1].Controls[0];

editButton.Visible = false;

}

else if (e.Item is GridDataInsertItem && e.Item.IsInEditMode)

{

GridDataInsertItem item = e.Item as GridDataInsertItem;

Button insertButton = (Button)item.Controls[item.Controls.Count - 1].Controls[0];

Button cancelButton = (Button)item.Controls[item.Controls.Count - 1].Controls[2];

insertButton.Visible = true;

cancelButton.Visible = true;

}

else if (e.Item is GridDataItem && e.Item.IsInEditMode)

{

GridEditableItem item = e.Item as GridEditableItem;

Button editButton = (Button)item.Controls[item.Controls.Count - 1].Controls[0];

Button cancelButton = (Button)item.Controls[item.Controls.Count - 1].Controls[2];

editButton.Visible = false;

cancelButton.Visible = false;

}

Basically, when I'm in readonly mode, I hide the ToDelete column, the Edit/Update/Cancel buttons and I do not display the commanditem controls.

In Edit mode, I display the ToDelete column and hide the Edit/Update/Cancel buttons. On the other hand, I display the command item controls.

Any help?

Thanks.
