Questions on UI for ASP.NET AJAX Forum

Hi,

I have my scheduler binded through web service. This part was working ok in the Q2 but then I updated to the Q3 and it's not working properly anymore.

I add an Attribute to my resources, say "X" for example and in the get resources from the web service I do the following:

Resource.Attributes["X"] = 1

when I get this Resource in the scheduler all the attributes dissapear. I don't know if that's normal or not. I use attributes to send extra information on the appointments and it works fine.

any ideas? is it a bug? or a normal behaviour? As I told you it was working fine for the Q2. This attribute [NonSerializedInControlState] may be preventing it from serialize?

regards,

jose

Datepicker bug in Chrome 26?

Hi.

I have an web app that are using a datepicker and it has started to run really slow after the first postback.
I found that the "slowness" only occured in Chrome 26 (26.0.1410.43). The same code worked perfectly in Chrome 25 (verifed on another computer and slow after upgrade to 26).

Any ideas what can cause this issue?

EDIT;
I having problems recreating the issue in a standalone project that I can post. (It is part of a large webapp). And it seems like its only a problem when the DOM is larger. I.e the example apps seems to run a little slower, but on my app it takes 3+ seconds plus to change the month in the calendar.

The thing I dont understand is that it works without any errors but its slow and only in Chrome 26+, the bottleneck seems to be located in the JS function Telerik.Web.UI.RadCalendar._navigatePrev/XXXX and its much slower after a postback.

EDIT 2:
The row that seems to take longer time is this.RenderViewDays(d, b, a, this.RadCalendar.get_orientation(), this.StartRowIndex, this.StartColumnIndex);

Any ideas why a postback could change the performace of the line above? I have stepped through the code and profiled it without finding any reason or bottleneck "hotspot".

When stepping through the code no errors or external (non-telerik-functions) gets invoked nor is any other client side functions attached.

The exact same code works perfect in other browsers (and earlier Chrome versions < 26).

[Solved] Non-Customized DatePicker in Filter

I created a grid while debugging.

<

telerik:RadGrid ID="RadSearch" runat="server" AllowFilteringByColumn="True" AutoGenerateColumns="true" OnNeedDataSource="RadSearch_NeedDataSource">

I see that the autogenerated date fields returned have a date picker in the filter.

How do I get that in my grid where AutoGenerateColumns="false" and my date column is in the .aspx page?
<telerik:RadGrid ID="RadSearch" runat="server" AllowFilteringByColumn="True" AutoGenerateColumns="false" OnNeedDataSource="RadSearch_NeedDataSource">

...

...
<Columns>

<telerik:GridBoundColumn DataField="Last_Update_Date" HeaderText="Modified" SortExpression="Last_Update_Date" AllowFiltering="true" UniqueName="Last_Update_Date" DataFormatString="{0:MM/dd/yyyy}" />
...

Thanks,
David

modal popup on Edit not closing

I have a radgrid with a details table with a formtemplate for editing. so it's a grid with two levels, when I am editing at the child level the modal popup show up fine but When I click the update button, it does all the work intended but does not close. It all works fine for inserting a record or canceling. and in the first lever both the edit and insert work fine, but just the child level edit is causing this problem. I've read a couple things to try and that is adding AllowAutomaticUpdates="false" and also adding

grdVcntn.MasterTableView.IsItemInserted = False
grdVcntn.MasterTableView.Rebind() to the _ItemCommand for the e.CommandName I have and neither worked.

I am also binding both grids in the backend using _NeedDataSource and _DetailTableDataBind. Is there any other sudgestions for fixing this.

ASP.NET AJAX Controls don't work

I've upgraded the web site to dot.net framework 4 and Telerik ASP.NET Ajax Controls 2013 Q1 (also tried 2012 Q3) framework 4.0.
It's Windows Server 2008, IIS 7,
Application Pool is .NET fr. 4.0.30319, Integrated mode, Local System account

Telerik Controls do not respond on click events.
RadTabStrip, RadComboBox, RadMenu, RadToolbar

Can see JS error in Web developer tools:
Uncaught ReferenceError: Sys is not defined Uncaught ReferenceError: Telerik is not defined
and many of those:
Failed to load resource: the server responded with a status of 404 (Not Found) ....

web config sections:

<handlers

<remove name="Telerik_Web_UI_WebResource_axd"/>

<add name="Telerik_Web_UI_WebResource_axd" preCondition="integratedMode"

path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource"

verb="*"

/>

</handlers

<modules runAllManagedModulesForAllRequests="true">

<remove name="RadCompression"

/>

<add name="RadCompression" type="Telerik.Web.UI.RadCompression"

/>

</modules

<pages enableViewStateMac="false" clientIDMode="AutoID">

<controls

<add assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagPrefix="telerik"/>

</controls

</pages>

ok, found it, i was using asp ScriptManager on the master which was not registered in web config
the solution is or register it or use the Telerik Rad.ScriptManager

ToolTip not showing during PostBacks

I have a RadToolTip on a Page. The ShowEvent and HideEvents are both from code.

If a certain param is passed through the URL, the ToolTip is shown during the PageLoad.

There is also a button on the screen that is in an UpdatePanel that has code in its CodeBehind method to show the tooltip. The Tooltip is NOT in the UpdatePanel (or any other UpdatePanel).

The Page_Load is working, but its not working on PostBacks.

Thanks for any help.
