I am using the "PostbackTriggers" property of the Upload control, as described on your web site article "How to Persist Uploaded Files".

This works well for the situation where I need a postback on a control, but that control is not a "submit" control.

The problem comes when I use one of the "submit" controls (listed in the PostbackTriggers property), but a server side validation error occurs, and the form data (including uploaded files) is NOT saved to the DB.  (This is a type of validation that can only be done on the server side.)  In that case, the upload control loses the uploaded file information.  Thus two questions:

1.   Is there a way on the server side to tell the control that an error has occurred, and to continue to persist the uploaded file information?

2.   Is there a way for the upload control to ALWAYS persist the uploaded file information until told on the server side that I have extracted the information I need from it?

How do I enable required field validation on a radcheckbox list item when it is part of a radwizard? I want to ensure that the user selects at least one item but when I hit the Next button to go to the next Wizard Step, it does not fire but proceeds to the next Wizard Step. Is this as designed?

Please provide assistance or some white paper article that can help.

Some of the Red controls can be used for server side only (no UI).
I typically use RadGrid to perform something that it is good at (grouping and arranging data) then export it to Excel. 
So if the UI is actually and output file this can be very handy, why have a web interface if you are actually created a report of some kind.
You had a Reporting tool kit, but times have moved on to Self Service and PowerBI type tools. It just seems that you have a lot of code in DLL that could be repurposed for process pipelines, not for a web interface, tho  the final results could be reused there.

I know that you have developed a RadBook, but only for Silverlight and WPF, which limits the visualization in devices in which it is not possible to install that plug-in or OS, so it would be good to have an HTML5 type control for ASP.NET UI with all the functionality of a Flip Book, and that the control can read a list of images, PDF, Office files, and other.

Thank you.

Update data values using drag and drop directly from the chart, something like this:

https://forio.com/app/powersim/powerwall/energy_consumption_details.html

A lot of customers would have this functionality without changing the HTMLChart controls.

The Telerik Bootstrap skin looks like it is Bootstrap, but it is not.  While it is easy to override a Bootstrap style to customize something, every time we do we end up on a support ticket to figure out how to make the same override in the skin.

One common area this comes up is the form sizing.  In Bootstrap, you can use a CSS class .form-group-sm to easily make the form controls smaller.  (There are several other classes as well for controls and form groups.)  The Telerik controls, like radCombobox or DatePicker do not honor this style, you need special Telerik CSS to get them to size.

The Bootstrap skin should have CSS included in it that handles when the Bootstrap control size classes are used.  That way when a Telerik control is placed in a div with .form-group-sm etc. it will automatically resize itself accordingly.

I'd like to use several masks in order to accept many phone numbers format. 
The component must accept phone numbers with these separators : "-", "/", "|" and space between figures. 
Here are some example of format that i mean:

1- xx-xx-xx-xx-xx 2- xx - xx - xx - xx - xx 
3- xx.xx.xx.xx.xx 4- xx/xx/xx/xx/xx 
5- xx / xx / xx / xx 6- xx|xx|xx|xx|xx 
7- xx | xx | xx | xx 

Evidently, the component needs to accept figures only. Most of the time, the phone numbers are inserted by a copy-pasted

It will be nice to have a countDown control with all the client/server events and the suite skins, which will enable the developer to show a visitor with a timer to complete a task (like finsih a purchase with a guranteed price for few minutes) and call a web service when the timer got to zero, and show a message to the client (with integrated Notificatoin object) about the price (changed or staed the same etc.) and let the developer decide if he wants to start the timer again or not.

Thanks,
ilan.

Hello, In one of the pages in our website, we have a RadGrid that uses client-side binding.  Above the grid, there's an "Apply Best Fit" button that executes the following JavaScript:
...
...

applyBestFit: function(tableView)
{
  var columns = tableView.get_columns();

  for (var i = 0; i < columns.length; i++)
    columns[i].resizeToFit(false, true);
}

...
...
In IE, it runs VERY slowly when there's 5,000 grid rows.

I found this post: "http://www.telerik.com/forums/radgrid-with-resizetofit-javascript-issue" and read the recommended link: "http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/performance/grid-performance-optimizations"

I understand that resizeToFit( ) is slow under IE.

I would like to propose that you add a new "MaxRowsToEvaluate" (or similar) parameter to resizeToFit( ) that can be used to control how many grid rows are evaluated when determining the widest size of a column.

With this new parameter, I could pass a value of 25, for example, and know that only up to 25 grid rows will be used in calculating the widest size of a column.  That would speed things up a lot I think.

Using this approach, the resizing would not be perfect, because a cell in the column beyond the "MaxRowsToEvaluate" number of rows may contain a value that's really long, but at least it wouldn't make the browser look like it's hung.

Thanks

Would be really nice if there was a clearly defined client-side object model for the radGrid. We created a function like the one below by deconstructing the header menu. The jQuery selectors to find the container and affected dropdown lists are really hacky and very brittle.  Reliance on magic strings means that upgrading to future versions is likely to break code like this.

Ideally we should be able to reference (and alter) a client-side filter operators collection like this: grid.headerMenu.filterOperators

function headerMenuShowing(sender, args) {
    var $container = jQuery("div[id^='" + sender.get_id() + "_rghcMenu']");
    var $lists = $container.find("ul.rcbList");
    var gridCol = args.get_gridColumn();
    var dataType = gridCol.get_dataType();
    switch (dataType) {
        case "System.String":
            $lists.find("li:contains('GreaterThan')").hide();
            $lists.find("li:contains('LessThan')").hide();
            $lists.find("li:contains('IsEmpty')").hide();
            $lists.find("li:contains('NotIsEmpty')").hide();
            break;
        case "System.Int32":
        case "System.Int64":
        case "System.Double":
        case "System.Decimal":
        case "System.DateTime":
            $lists.find("li:contains('GreaterThan')").show();
            $lists.find("li:contains('LessThan')").show();
            break;
    }
}

Hi guys,

Your barcode web control works great, but we have a need in several patient care engagements for the Aztec barcode protocol. We'd love to use Telerik exclusively and not have to use some other set of tools on these engagements.  

Thanks for considering it.

The default behavior of the mobile menu is the following: when popup with root items is opened, its height is calculated depend on root items count and their height. After opening a sub-menu, where items count is different, the popup height is not updated.

The suggestion is to add a functionality to popup menu to update its height every time after opening a next item.

Currently, opening the CustomColorPallete popup always selects the #808080 color.


To have this behavior with the current implementation of RadColorPicker, you can use this custom code:


<telerik:RadColorPicker runat="server" ID="RCP" EnableCustomColor="true" OnClientLoad="OnClientLoad" />

<script>
    function OnClientLoad(sender, args) {
        $telerik.$(sender._customColorButton).click(refreshPalette(sender));
    }

    function refreshPalette(sender) {
        return function (evt) {
            var colorPicker = sender;
            var selectedColor = colorPicker.get_selectedColor() || "#808080";
            colorPicker._updateHslPaletteElementsUI(colorPicker._getRgbFromHex(selectedColor), null, true);
        };
    }
</script>
