I'm guessing the preview updates on posts because it updates when I add/remove/update filter expressions and groups, and it updates when I load the grid. I would prefer it to update as I'm making changes, because to me, a "preview" doesn't really count if I have to load first. For example, If I only add one filter expression, the preview doesn't show anything...until I load the grid. If I add three expressions then a group expression, the first three expressions will show in the preview correctly, but then the group expression doesn't, because there's no server post between choosing the last expression value and loading the grid. So, the question - is it possible to update the preview expression in "real time"? Code for reference:

 

I want to be able to achieve a scnerio where the user will click the apointment slot in rad scheduler and then autopopulate the fields i have futher down my form is their a way to have like a reserved status of the slot until the apointment is properly booked?.

Hi thee,

I am using Rad Scheduler ASP.Net version 2015 Q1.

 

I am populating appointments using a web service, passing in custom properties and that all works wonderfully.

I have a scenario where I wish to show appointments for a set of resources, and then allow the user to see the data just for a subset of those resources. This selection is via a set of checkboxes. While it is easy to just show the appointments for the selected resources using rebind(), the un-selected resources still show in the grid.

In the attached image, I want the Scheduler to just show the data for the users that have are checked, not for "Grant" or "Roger". My code successfully won't show the appointments for "Grant" or "Roger", but does not remove them from the grid.

 

In this scenario I am happy for a post-back to occur if necessary, but when I do that the resources that are used to generate the grid are re-used, rather than being repopulated. Is there any way to force the resources to be repopulated from the client-side?

I am using the RadUpdate/ProgressArea control to allow a user to upload a file and then view the status of the import process. The first progress bar is handled automatically during the update process by the progress area. The second part of the process, the import, I am using the secondary progress bar to give them feedback (processing line x of y).

I am trying to load about 29 thousand rows of data into the kendo spreadsheet and I get the above error. What I am doing is converting data from a ExcelPackage to a Telerik.Web.Spreadsheet workbook on the back-end. Then I convert the workbook via the ToJson method, send that data to the front-end, parse the received string data to a JSON and then load that JSON into the spreadsheet directly as a object or via the spreadsheet.fromJSON(data) method.

It works for less data, but doesn't for this. Also I can have hundreds of thousands of rows with no problems but with data it's another story. Can you tell me if there is some better way to do this, or how to work around this error.

Thank you in advance.

Hi,

I want to make mediaplayer playist back color black. I also want to change the font color and image size.

 

Could you help.

Hi, I have issues with custom button / markup in RadEditor. Here's my scenario:

 

- I have a custom button added through: Telerik.Web.UI.Editor.CommandList[rteButtonCommand] ...

- Then I show some external dialog ( editor.showExternalDialog(...) ) which returns back some markup.

- I inject that markup where the cursor was, ie. like:

<div class="some-css-class">

[myCustomComponent]123456789[/myCustomComponent]

</div>

- Instead of having that custom tag, I would like to show some image instead indicating what kind of component it is and more importantly be able to select it like an image and be able to move it or bring back the dialog with selected values. 

 

I read quite a lot of reference, but couldn't find anything related. 

 

Can anybody help me with this?

 

Thanks
