Hello,

I've been facing a bug in the filter textboxes of the radgrid as following.

The Problem:
When the user press Enter key on any text box of the filter textboxes it will always display the filter menu of the first column.

Debugging:
After doing some debugging, I noticed that the filter image is of type "Submit" which the browser considers the submit button of the form and invokes it, so while there are no submit buttons on the form, the onclick event of the filter image is invoked resulting in the menu displayed by mistake.
In FireFox, the menu is displayed at position 0,0.
In IE, the menu is displayed relative to where the mouse positioned.

To Reproduce:
1- Put a radgrid in a webform page while flitering is enabled and do set autopostbackonfilter=false, don't put any other elements in the page, to be precise no submit buttons.
2- Focus on any of the filtering textboxes and hit enter.

I have a grid that is grouped by one field and has as its rightmost column a template column that contains a user control.
This user control just renders as a table with one row and a not-fixed number of columns, the cells containing an 'X' character or a space. Nothing fancy.
My trouble is aligning this table to the right.
In IE9 i can't get it to align to the right. In IE9 compatabilty mode the grid rows align properly, the header row doesn't.
In PDF export the table never aligns to the right; in Word export, it does so nicely.
I tried different style attributes on different levels, wrapping the table in a <div> element, to no avail.
There must be something i missed. Can someone point me in the right direction?

I'm trying to implement hierarchial grid client update based on events I get from server.

JSON serialized array of objects is received from server and bound to grid with set_dataSource() either on MasterTableView or on one of detailTables. The problem is - respective detail tables only appear for rows that were bound to master table on server side. 
E.g. if I bind array of 0 records to masterTable on server-side and bind array of 3 records on client-side then - get_detailTables().length returns 0. If I bind 2 records on server side and 5 records on client side then - get_detailTables().length returns 2. Of course UI doesn't show that newly added rows can be expanded too. I'm using HierarchyLoadMode="Client" for master table.

Is there a way to workaround this and have detail tables created appropriately without additional server calls from grid?

Hi all ..
briefly talk about my project , i want design  my asp.net app view  like win desktop .. therefore i use radwindow like telerik ex. http://demos.telerik.com/aspnet-ajax/window/examples/radwindowandmdi/defaultcs.aspx

Hi,

I'm trying to get the checkbox reference which is inside the grid using the property UniqueName.
It returns me this ctl01$ctl03$chk which is actually the name of the control rather than the id.

I noticed that the id is exactly the same, just that the $ symbol is replaced with _
which means the id is ctl01_ctl03_chk

I just need some confirmation that the only difference with name and id is the symbol $ and _
because i replaced the symbol $ with _ in order to get the reference of the checkbox.

Is this advisable? I'm just concern that in future telerik might use some kind of other symbols that might
render my code useless. Please help.
 
Regards,
Dexter

I'm using The Q3 2010 Scheduler control with a Web Service data source, in  class MyDbSchedulerProvider
 public override IEnumerable<Appointment> GetAppointments(RadScheduler owner)
 {
      User objUser = (User)HttpContext.Current.Session["User"];
}

in function GetAppointments i'm use object HttpContext.Current.Session, Minor run all good when !isPosback, but when my execute event Update then HttpContext.Current.Session is null.
please help me.
thanks!
