RadComboBox Autocomplete Selection to ListBox

I have a need where when I 'typeahead' to load the combobox... each time an item is selected it is automatically added to another listbox on the page (not removed from the combobox list collection). I don't really want it to remain selected in the combobox. Or displayed in the text field.

Using FileExplorer With A Custom DB Provider

Hello,

I'm trying to create "virtual" directories for our file-system and then display them using the fileexplorer from Telerik.

I have a table called FILES that looks something like this:

id int (key)
filename varchar(50)

A table calle VERZEICHNIS that looks like this
id int (key)
directoryname varchar(50)
vorgaengerid int

and a many to many connection between them

FILES_VERZEICHNIS

filesid int (key)
verzeichnisid int (key)

I've got it to display everything just fine using a custom file provider, but I've run into two problems.

One, because the files come from Internet users we've created a system where the filename displayed can exist more than once in a directory (the id is the key). When the Fileexplorer Itemcommand is fired, it only passes the path. I can probably append an id to some part of the filename, but this is unsightly and exposes information to the user they don't need. Perhaps there's a way I can get at the source node and destination node and the underlying dataitems, but I can't find it.

Two, I've probably set up the page wrong, because when the treeview attempts to refresh the wait indicator never goes away and I get four javascript errors. Three say "a is undefined" and the fourth says "Fehler: $get(this._currentDirectoryInputID) is null
Quelldatei: http://aspnet-scripts.telerikstatic.com/ajaxz/2011.1.315/FileExplorer/RadFileExplorer.js
Zeile: 674 "

Any help with either of these matters would be most appreciated.

Exceptions on drag&drop files (e.g. images) and links from web

Hi,
if you try to d&d a file or a link to a file from a website (not from LocalSystem) asyncUpload functionality is being broken with
"file is undefined" exception

var fileApi = function (asyncUpload) {

$.extend(this, {

_processFiles:

...

$.each(files, function (index, file) {

var row = index == 0 ? context.initialRow : module._appendRow(context.initialRow.id);

module.trigger("FileSelected", row, input, file.name, (index + 1) == context.progress.totalFiles);

context.map.push({ file: file, row: row });

});

...

}

RadWindow caching previous state?

My scenario:

I have a RadGrid where each item has a link that will open a RadWindow. Inside each radwindow, I have a textbox that will add comments, and once a comment is added, a grid will show in it's place with comment details inside. We only allow one comment, so when a user comes back to that item and clicks the link again, the radwindow will open and only show the comments grid. My issue is everything works fine until I close the radwindow, and open a new window where a comment hasn't been added. I see the comment box (as I should), but when I close this window and go back to the window where I just added the comment, it shows the comment box instead of the comments grid (even though it hits the logic in the codebehind), until I right-click and choose refresh. I'm using IE8. I've tried DestroyOnClose=true and that worked, except after it builds the initial RadWindow, if I close it and I click a new link to open a new window none of the properties from the rad window manager are saved and a default radwindow is opened in it's place.

Any help on this would be greatly appreciated. If I haven't been descriptive enough I can provide more details

Content to Share

I'm a little surprised there is no way to default this information. I can understand letting the user edited what is being sent but in my case what is being shared is the result of tasks they have completed and the user really doesn't have easy access to all the data.

I hope that this functionality is being considered. ( or that I'm wrong and it can be defaulted )

SortExpression

I have a radgrid bind to a list of object A which contains another object B as below

Class B
{
string name;
}
class A
{
B b;
}

for one of the GridBoundColumn, it is bind to b.name with DataField and SortExpression, however some of object A had null vaue for field b, so the page is throwing exception.

how can I config it so that if field b is null for the object A, it just uses empty string "", otherwise bind to b.name?

thanks.

Is there any control that would allow me to achieve this?
Please advise.

“Input string was not in a correct format”

I am getting the following Exception:

"Input string was not in a correct format" on DataBind() line.

I believe what is happening is that the poll is being created with numbers/integers and Telerik is being clever and treating them as ints instead of as strings.

Is there a way to tell the telerik RadChart to either treat everything as strings or format things on a per entry basis?

These two people have encountered a similar problem;

I have mocked the db data as follows and the same issue is present.

List<PollContainer> pcl = new List<PollContainer>();
        pcl.Add(new PollContainer(111, "1", 0));
        pcl.Add(new PollContainer(112, "2", 0));
        pcl.Add(new PollContainer(113, "3", 0));
        pcl.Add(new PollContainer(114, "4", 0));
        pcl.Add(new PollContainer(115, "5 - 10", 0));
        pcl.Add(new PollContainer(116, "10+", 0));
        trcResults.DataSource = pcl;

trcResults.DataBind();

///////////////////////////////////////////////////////////////////

List<PollContainer> pcl = new List<PollContainer>();
        pcl.Add(new PollContainer(111, "1d", 0));
        pcl.Add(new PollContainer(112, "2d", 0));
        pcl.Add(new PollContainer(113, "3", 0));
        pcl.Add(new PollContainer(114, "4", 0));
        pcl.Add(new PollContainer(115, "5 - 10", 0));
        pcl.Add(new PollContainer(116, "10+", 0));
        trcResults.DataSource = pcl;

It seems Telerik doesn't like the strings "1" and "2"?!

I have tried adding

Appearance-ValueFormat="General"

to <XAxis>

[Solved] GridDataTimeColumn and RadDataPicker

Good afternoon, my name is John and I work in Brazil. I'm doing a project and use some components of Telerik, but I doubt that this is a difficult problem.
The problem is that I can not leave my GridDataTimeColumn in an empty field, I mean, is not required the user to select a specific date.
Only I would like the field of my GridDataTimeColumn stay empty if the user selects not the date on RadDataPicker.

The lower image is an example that you reported, I could not understand what the code that makes this event. How you guys managed to leave the column blank DataTimeColumn, if I do not select a specific date?

Thank you for your attention!

Is there any way to create RAD Grid control having the same UI as that of Query Filter Grid control in Microsoft CRM dynamics?

I need to create grid control having the same UI as that of Query Filter grid control in Microsoft CRM dynamics. That can support grouping of filter in the same way as well.
