I have a DataTable that I am setting as the datasource of a RadComboBox. The DataTable has about 1300 entries in it. If I use the standard Windows ComboBox, Autocomplete works quickly, and I have no issues with it. If I try to use the RadComboBox, the first time I enter the field and start typing, the first letter auto-completes fine, but it hangs for 5-10  seconds upon typing the second letter into the field, before it matches values for autocomplete. And  if I click the arrow to display the drop-down list, the form kind of hangs, until I click around for a bit.   Any idea what is causing this, and what I can do to avoid it? No way I can expect my users to put up with that.

Hi ,
we are using RadSchedulerRecurrenceEditor in web application.
so through web application we are saving recurrence rule in database.(in string format)

now we want to read this recurrence rule in windows service and find occurences.
but when we try to add telerik.web.ui reference in windows service its giving error while building.

Error 1 The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?) 

so do we have different set of dll's for windows service? if yes from where i can get it?

and what approch i shoud follow to get my requirment?

waiting for your reply...

I am new to the Telerik Windows controls(Usually a Web guy), but do you guys not have a Rich Textbox Editor for Windows?  I see one for WPF, Silverlight and ASP.NET, but not for Windows...unless I am missing something.

thanks

hi sorry I'm new to telerik, provide long tryouts, and I liked, but my question is, what is the difference between Q1, Q2 and Q3?

Hi,

I have created a system in which I edit a recurrence from a web page but want to use a windows service to process the recurrences. 

I have the web page creating a recurrence string as shown below:

DTSTART:20100319T000000Z
DTEND:20100319T000100Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=FR;WKST=MO

I am then in the service using that string to generate the next date in the sequence, change the recurrence string and save back into the database.  In addition if the recurrence is of a finite count I need to decrease the count that is within the string.

Other than manipulating my original string and saving that back into the database how do I do this?  The class structure is completely differnt to it's web counterpart which seems a little odd given that in theory the functionality should be the same.

Regards,

Jon

Is it possible to replace the standard +/- icons for exanding and collapsing nodes with my own custom images?

I found this article:

http://www.telerik.com/help/winforms/treeview-working-with-nodes-node-images.html

Which suggests this is possible.  However I was struggling to find the StateImageKey property and a further article on the web seemed to suggest it was removed from the laster version of the components.

Any help gratefully recieved.

Hi,

I have a PNG image (round button) and I want to use that as button. I have tried setting the image property to that image in radButton control but it shows the transparent area as well. My Question is how can I use round images as buttons and is the procedure for using transparent images same for all controls?

Thanks

Hi!

By default all properties from row object (databound item) goes to Conditional Formatting Rules Manager.

You can take a look at the attachment. 

1. How can I select which columns should be available in this window?
2. Can I somehow disable conditional formatting for whole grid? How to remove this option from column header context menu?

 

I have found option for hidding column chooser: radGridView1.AllowColumnChooser but I cannot find similar option for hiding conditional formatting.

We are trying to logically determine the next row to select if the currently selected row disappears. Users can select a row and perform an operation that may or may not cause this row to reappear after the grid is refreshed. We cannot determine in advance if the currently selected row will be in the refreshed dataset, and we need to perform a full refresh to display new data that may have appeared for the user. If the current row is in the refreshed dataset, that is no problem. Each row contains a unique identifier in a hidden column and we can save the unique identifier and reselect this row after refreshing.

The problem occurs if one or more of these rows disappear after a refresh. We want to move the selection to the previous row (right above the selection) as displayed to the user with sorting and grouping applied. How do we determine which row this would be?

Basically, we need to be able to answer this question: Which row is visually displayed immediately above the currently selected row?

We have it working for the most part, but the code is very complicated and still does not work exactly as we would like. For example, if the user selects the first row in a group and it disappears, the best that we can do is to go to the previous group and select the first row in that group. We would like to select the last row in the previous group. There are also problems if the entire group that contains the currenty selected row disappears.

The GridNavigator won't help because I don't actually want to select the next or previous row. I just want to know which row I would select if I were to call the SelectPreviousRow or SelectNextRow methods, find the unique identifier value in this row, and store it to select the desired row after refreshing.
