Hi guys,

Hope you all had a good Xmas/New year.

We are using the Ajaxspellchecker that is built into the radeditor and I have come across an issue where the spell checked content is being cached on the server.

We use a Big IP F5 load balancer to serve up all content and it is this that is holding on to the cache. In order to get around this we need to add rules of what files to exclude from cache. Are you able to help in advising what files we would need to exclude to prevent the spell checker from being cached?

Thanks for your help.

Height of grid inconsistent and is cut off short

Hi,

I have this weird behaviour on one of my radgrid where the height is cut off. So the area where the rows are displayed are shorter ( I think its the rgDataDiv) .I have to say the page i have it it is quiet complex and involves a lot of dynamic controls... not sure if this is the cause...but this behaviour is only seen after a sequence of clicks ( i can always reproduce it ).

Landing on the page originally does not show the bug, but after a series of clicks ( a consistent pattern ) it happens... I'm gonna try to post my grid source and the behaviour and the generated HTML first to see... hopefully its just a stupid setting i forgot to set which you can point out...

Otherwise, If required, I'll post the full page...
Here's the Grid... Notice I've forced it to have a height of 493px.

<div style="margin-left: 12px; margin-top: 40px; clear: both;">

Attached are 4 images:
Generated HTML output of the Grid before; Note the height in the outer div of height 493px and the inner rgDataDiv ( I'm assuming it is inherited from the RadGrid declaration )
Generated HTML output of the Grid after; the height of outer div is still 493, but the rgDataDiv is now set to 300 px? Not sure where this comes from .
Display Before and After

Additional Information regarding the set up , in case it is related to the way this grid is set up:
I have modified the gridCSS so that it displays according to a spec i received... The Rows are always grouped by the category ...

Regarding the Page / UC set up, I have a Page 1 which uses a Master Template. In the Page, it has 3 states ( 3 custom NON-Telerik TABS ). By default it calls this dynamic UC (call it TAB 1) which has the RadGrid. When I Click on TAB 3, it calls another Dynamic UC replacing the content of the placeholder completely. Now I leave this page to Page 2, then come back to Page 1. This time, because I have a Session variable to save the state of the last Visited TAB in page 1, It loads Page 1 with TAB 3. When I click on TAB 1, to display the RadGrid , this is where this behaviour is obtained.

Trying to copy/access datasource

I have inherited a report which has been bound at design time using the front end tools/wizards.
A datasource has been bound to a control but there is another control on the report which wants to use a subset of that datasource. Basically it needs to get the number of records where the addedDate field is within the last 6 months.
I thought I would be able to copy the datasource into a datatable and loop through them chacking the date manually but it wont let me cast the datasource as a datatable.
Any ideas how to work around this?

Binding Radgrid to Business Object Displays Empty Values

I am trying to bind a RadGrid to a generic list of business objects using the OnNeedDataSource event. The grid displays the correct number of rows, however, the values for the fields are empty. I can bind to a datasource object without a problem, but I am going to be adding additional functionality where this method will be necessary. For simplicity sake, I am just trying to bind a single exposed property from the custom class object in the list.

No items to view</div>

Alphanumeric filtering not working

I am using the RadComboBox to display a list of employees, along with their employee numbers (in the same field, in parentheses). The employee numbers have a fixed two character prefix ("NB") followed by 6 digits ("NB000342", "NB191561", etc). So the field in the combo drop down looks like "Smith, John (NB117654)". I am loading the full list on-demand. The filtering works fine until you type a digit, then it returns nothing. It matters not whether you type only digits or whether you mix digits and text; the presence of any digit(s) results in no matches. Is there a setting that I am missing that enables alphanumeric filtering?

Scheduler Web Service invalid call

Hi everyone/ I'm currently using RadScheduler to create my own Scheduler. For better user experience, I used Web service binding, but only the GetAppointments is invalid. I use my own Advance Template with no resource, only passing extra attributes.
But eveytime when I Update or Insert, a message box appears with the text "Invalid web service call, missing value for parameter 'appointmentData'".

ModalPopupExtender dynamic user control hosting RadGrid Filter Menu behind Modal Popup

Hi I have MasterPage/Content page scenario the Content page loads a ModalPopup using the AjaxControlToolkit that loads a user control that has a RadGrid inside a FormView controls EditItemTemplate. The problem is that the FilterMenu/Group By etc only shows up behind the modal popup and is not click able. The same issue for that pager of the RadGrid in that it's Page size combo is not selectable.

I have tried the following:-
1). In the RadGrid's Init event setting the RadGrid style to a higher z-index than the popup
2). changing the FilterMenu and HeaderContextMenu CssClass to one with a higher z-index
3). Setting the RadComboBox in the pager to have a style with a higher z-index

but none of this works. What do I try next??
