I am executing the code below following a refresh from the database.  What I'm trying to make happen is that after a process completes to update one of the rows, the data is refreshed and the previously selected record is still selected for the user and scrolled into view.  When I execute this code following an update routine the grid is scrolled completely to the bottom, and both the record I selected and the visible row within the grid (even though it is now a different row) is selected.  If I execute it from a command button, the first record is selected and the grid is scrolled completely to the top.  What am I doing wrong?

hello,

i have a RadRibbonForm that has a skewed icon in the Form's titlebar.

i have removed and replaced dozens of times - it does not help.

i cannot start over on a new form - i have too much invested in this form already.

does anyone have any ideas of how to resolve this?  what property is set to make it behave this way?

I want to prevent a user from using the property grid context menu to reset a value that has changed. I tried setting the IsModified property to false, but it is read-only. Is there another way to make sure the "Reset" item in the context menu is always disabled for a specific property grid item?

Well, may i don't understand something in this page http://www.telerik.com/help/winforms/gridview-exporting-data-export-to-csv.html
or i have a missing dll?

what I'm doing wrong?  i'll appreciate any help you can give me, thanks.

I would like to go to the database every time a user inputs a filter and then clicks on the filter button.
So 2 things are different here.

1. Filter does not get applied as user types in the filter, but only when user clicks on the filter button for that column.
2. When user clicks on the filter button, then a new result set is returned from database based on filter condition. The results of this filter query will re-bind the database.

Thanks

Hello All,
This is the code I am using to set the back ground color of the cells in the calendar control based on the min date.
1)I open the calendar  the back color for all the dates less than the min date is showing up as red. Let us assume the min date is 6/12/2000
Now when I go to next month(i.e., 7/12/2000) the back color for all the cells in that month is supposed to be green. But this is not the case. Whats happening is that some of the Cells color is still Red and the others are green. But if i reopen the Calendar all the dates show up as Green. Now if I go back to 6/12/2000 all the dates including dates less than 12 th of June are showing up as Green too.
Is there any other event in which this code needs to be executed when i change the month using the arrow on the top of raddatepicker. I am using raddatetimepicker for winforms. Q3 2010 version. I do not see a viewchanged event here. Any help would be appreciated.

Thanks a lot.

Hello,

I would like to disable the ContextMenu popup fade-in animation for a RadDock, but I cannot find where to do this.

I know how to disable the contextmenu animation for a RadGrid, for example, by subscribing to the grid's ContextMenuOpening event and using e.ContextMenu.AnimationEnabled = false; when the event fires.

However, the RadDock context menus are handled by the ContextMenuService, which only has the ContextMenuDisplaying event, and in this events handler, there is not a reference to the actual context menu object, just a list of the menuitems and the upcoming display position.

I know that ThemeResolutionService.AllowAnimations = false; will accomplish this, but this will also disable all animations across the application, which I do not want to do. I just want to disable the ContextMenu fade-in animation.

Any advice on how to do this?

Thanks,


Michelle

Error:  Cannot access a disposed object. Object name: 'GridViewSynchronizationService'.

Scenario: This error only appears to happen when I'm utilizing an EventLogEntryCollection as the datasource and refreshing the datasource via a timer event. The form is a simple event log monitor.

The error occurs randomly on either of these lines (this is from within a custom control):


The above DataCache object is a dynamic property that is populated by the code below.

EventLog e = new EventLog(EDI.Definitions.EVENT_LOG, ConfigurationManager.AppSettings["EventLogServerName"]);

The above snippet is from a form that is consuming the custom datagrid control (so the dgResults object is distinguishable for anyone reading).

I can't recreate the issue as it just randomly appears from time to time.

Hopefully this is a known issue of some type and there is an easy fix.  I saw that clearing the relations might work, but that doesn't seem to be working for me.

Ideas anyone?  Thanks in advance! Let me know if more is required.

Hello, I have a question. How can I edit themes. Radcontrols already come with a few themes but none I really like, so I want to make my own how can I edit the themes and add them just like a regular theme for me to use every time?
