Hi,
I use the TimeView with a custom collection according to http://demos.telerik.com/aspnet-ajax/calendar/examples/datetimepicker/customcollection/defaultcs.aspx

The custom collection is needed because the user should be able to select the time 23:59. But this does not work in other timezones: when not in the same timezone as UTC time, the picker "results" in another time than the selected. For example, if I pick 23:59, the time in the textbox results in 21:59 for my timezone. Every other time is ok - for example if I pick 12:00, it picks the right one. It seems that the property UseClientTimeOffset does not work for this particular time 23:59?

 

 

 

I created a class in order to use the UseClientTimeOffset property.

I have created a Grid with filtering using the RadGrid with the following markup

As per your example in Grid -> Filtering Template Columns. I am using Telerik version  2009.3.1208.35.

The page render's and the grid display full of data. I filter on every column except the custom column and the filtering works great. When I select a value from the drop down, the grid empties and no records are displayed.

Any idea's?

Thanks,
Luke

I have a problem concerning asp:dropdownlist control did not postback with RadAjaxManager in .net framework 4.0. It works on .net framework 2.0 in MS Visual Basic .net 2010 and converting it to .net framework 4.0, asp:dropdownlist control didn't postback. Any idea on this?

Hi,

i have used telerik rad grid client-side programmatic binding. Binding is working fine but when we try to filter the data it is not accepting numeric values like for 28 it is taking as ( , 29 it is taking as ). So, what i understood is it is converting the numeric value to ASCII code.

how to solve this problem?

Thanks in advance. 

With the RadGrid, is it possible to change the look of the thing you're dragging when using Row dragging? Or does it have to be an exact copy of the row item?

Hello. Thank you in advance for your help and advice.

Client is using Telerik RadEditor for ASP.NET AJAX with Microsoft Internet Explorer 8 web browser. A problem exists with the "Find And Replace" dialog box in this browser. You can reproduce problem on the current (17 August 2012) RadEditor demo page. Please try these steps.

1. Open RadEditor demo page using Internet Explorer 8
2. Click in RadEditor text area to set focus. Press Ctrl+F or click "binocular" icon to open "Find And Replace" dialog
3. Enter text in the "Find" input field. Text should actually exist in document. For example, enter "HTML" or "Microsoft"
4. Press Tab key to focus on "Find" button. Press Enter key to search

After you press Enter key. RadEditor will correctly locate and highlight the word in the document. But also the highlighted word is deleted and replaced with a linebreak character. It seems that the Enter keypress event is not terminated correctly. Similar problem exists when using Spacebar key to activate Find button. The search word is highlighted but then it is deleted and replaced with an empty space character.

This problem was not existing in a previous version of RadEditor. (It seems to be new problem in about last year.) Also it works OK in other browser like Mozilla Firefox. Please is there a way to make Enter key work in "Find And Replace" dialog box in Internet Explorer 8?

Thank you.

Hi Telerik team,
I have an issue with the Export to Excel-button. The button works fine until I perform an action on the radgrid (such as removing/adding columns, sorting or paging) - after that, the Export to Excel -button no longer has any effect.

My radgrid is ajaxified through a RadAjaxmanager. It does not reside in any kind of updatepanel. The grid is on a sharepoint page.

I've implemented the necessary disabling of ajax in the clickfunction of the button.

function onRequestStart(sender, args) {
    if (args.get_eventTarget().indexOf("ExportToExcelButton") >= 0) {
        args.set_enableAjax(false);
    }
}

So it seems like the button functionality is broken after an ajax request is made.
Any suggestions?

hi

i have implmented successfully the following demo

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandcombo/defaultcs.aspx?product=grid

what i would like to do now is extend it to allow multi column filtering , is this at all possible ?

Peter

I have a RadGrid that has another RadGrid nested which also has another nested RadGrid. So there are 3 levels: Level 1 has information about a costumer, level 2 has information about customer´s purchases, and level 3 has info about products that the costumer has bought during the purchase. 

Now, I need to be able to select the level 2 row (purchase) and then access the data on all levels to construct a receipt of the purchase. I was able to add the checkbox column to level 2 by adding the GridClientSelectColumn to the column collection and enabling the client side row selection. So visually I have what I need. But my big problem now is: 

How do I access the data (contents of the cells) on all levels when I press a "print receipt for selected purchase" -button? I tried accessing it rought the RadGrid1.SelectedItems, but it was null. With just one RadGrid setup I could just use RadGrid1.SelectedItems[0].Cells, but that wont of course work with nested grids.

This might be a noob question, as I am very new to Telerik components. Any recommendations for "RadGrid for dummies" tutorials are welcome.

Thanks in advance! 

I put a Filter control and Save button in one page and I also hide the Apply Button for Filter control. I don't find a way to get expression result after I click the Save button. Anybody know how to do?
