Weird javascript error Ajax'd RadGrid and RadInputManager

Hi

I have a weird error... I have a bunch of TextBox's and a RadGrid which is ajaxified with auto updates enabled. These TextBox's, and the TextBox's in the editable template in the RadGrid use a RadInputManager.

<telerik:RadAjaxPanel ID="RadAjaxPanel" runat="server" LoadingPanelID="AjaxLoadingPanel">

<telerik:RadGrid ID="rgPriceLists" runat="server" Width="600px" Skin="Default" AutoGenerateColumns="false" DataSourceID="objPriceLists"">

<MasterTableView EnableNoRecordsTemplate="false" Width="100%" DataKeyNames="PriceListId" AllowAutomaticUpdates="true" EditMode="InPlace">

<Columns>

<telerik:GridBoundColumn HeaderText="Name" DataField="Name" ReadOnly="true" />

<telerik:GridBoundColumn HeaderText="Pub" DataField="Pub" ReadOnly="true" />

<telerik:GridTemplateColumn HeaderText="Price">

<ItemTemplate>

<asp:Label ID="lblPrice" runat="server" Text='<%# GetCulturedPriceOrBlank(Eval("Price") == null ? 0 : (decimal)Eval("Price"), 0.0m, (string)Eval("Pub")) %>' />

</ItemTemplate>

<EditItemTemplate>

<asp:TextBox ID="tbPrice" runat="server" Text='<%# Bind("Price") %>' Columns="7" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Tax">

<ItemTemplate>

<asp:Label ID="lblTax" runat="server" Text='<%# GetCulturedPriceOrBlank(Eval("Tax") == null ? 0 : (decimal)Eval("Tax"), 0.0m, (string)Eval("Pub")) %>' />

</ItemTemplate>

<EditItemTemplate>

<asp:TextBox ID="tbTax" runat="server" Text='<%# Bind("Tax") %>' Columns="7" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Active?">

</ItemTemplate>

<EditItemTemplate>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridEditCommandColumn ItemStyle-Width="40" ItemStyle-HorizontalAlign="Right" ButtonType="ImageButton" UniqueName="EditCommandColumn" />

</Columns>

<telerik:TargetInput ControlID="tbPrice" />

<telerik:TargetInput ControlID="tbTax" />

</TargetControls>

</telerik:NumericTextBoxSetting>

</telerik:RadInputManager>

As you can see, I have 2 blocks in the RadInputManager commented out. The RadGrid correctly Ajaxifies the edit/update commands when these blocks are commented out. However when i uncomment out 1 of those RadInputManager blocks, I get a javascript error on the initial edit "a is null" in Telerik.Web.UI.WebResource.axd

Why?? :(

When I sort the ID twice.

Hi,

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Please reply

[Solved] Override ExportToExcel function

I like the look of the default commanditem, and have set <CommandItemSettings ShowExportToExcelButton="true".

However, I like to control the exporting to excel myself.

I was thinking to write my own exporting code in the grid.ItemCommand:

    Select Case e.CommandName
      Case "ExportToExcel"
       [Export to Excel code]

However, the built in exporting still fires.

Exchange Provider: EWS 2007 Recurrence Time Zone Bug

So there’s an apparent bug in Exchange Web Services (Exchange 2007) that screws up the display of recurring calendar events when we use EWS. Basically, the returned XML contains DateTimes for recurring events that are provided in 2 different time zones: local time and zulu time, making events at certain times of the day disappear.

It’s noted in the Microsoft Press book “Inside Microsoft Exchange Server 2007 Web Services” (http://www.microsoft.com/learning/en/us/book.aspx?ID=10724&locale=en-us ). Excerpt attached.

The book recommends that we wait until Service Pack 1… however we have just installed SP3 and the issue remains. It *looks* like the Telerik Exchange provider is trying to work around it in ExchangeSchedulerProvider.cs with the following method:

public RecurrenceRange ConvertToRecurrenceRange2(EndDateRecurrenceRangeType endDateRecurr)

{

RecurrenceRange range = new RecurrenceRange();

range.Start = endDateRecurr.StartDate;

range.RecursUntil = endDateRecurr.EndDate.Date.AddDays(1);

return range;

}

Has anyone dealt with this and, if so, how?

Thanks in advance

Jonathan

Text Wrap, line highlight issue in template

I have a templated combo showing Product Title, System, and Cost.



<

telerik:RadComboBox ID="radcmbProduct" runat="server" Width="400px" Height="200px" AllowCustomText="false" EmptyMessage="Select a Product" EnableLoadOnDemand="True" ShowMoreResultsBox="true" EnableVirtualScrolling="true" HighlightTemplatedItems="true" MarkFirstMatch="true" NoWrap="true" OnItemsRequested="radcmbProduct_ItemsRequested" OnItemDataBound="radcmbProduct_ItemDataBound">

<HeaderTemplate>

<ul>

<li class="col1">Title</li>

<li class="col2">System</li>

<li class="col3">Price</li>

</ul>

</HeaderTemplate>

<ItemTemplate>

<ul>

<li class="col1">

<%# DataBinder.Eval(Container.DataItem, "Title") %></li>

<li class="col2">

<%# DataBinder.Eval(Container.DataItem, "GameSystemName") %></li>

<li class="col3">

<%# DataBinder.Eval(Container.DataItem, "Cost") %></li>

</ul>

</ItemTemplate>

</telerik:RadComboBox>

The Product Title is going to be longer than I can fit , I have tried turning NoWrap off and Cost end up on the next line but I am having enough issues with the highlighting that I turned it back on. Here is the CSS:

.col1

, .col2, .col3

{

float: left;

width: 100px;

margin: 0;

padding: 0 5px 0 0;

line-height: 14px;

}

I want to get the highlighting and perhaps the text wrapping to work together so it looks good. Here is what it looks like now (see attachment)

I am not sure what is missing but it will not highlight based on the template and even if I turn nowrap on as it is, the highlight line is way above where the mouse is, etc.

Delete/Remove a RadDock within a RadDockZone

I am trying to figure out in code-behind how to delete RadDock1 from a RadDockZone/RadDockLayout if I click on a button. And how do I programatically add a RadDock by clicking on a button?
