Hi

I have developed an external .js file for an ASP.NET system which executes the following...

function ProcessUpdate(arg) {

    var ram = $telerik.$("[id$='RadAjaxManager1']").attr("id");

    var ajaxManager = $find(ram);

    if (!arg) { ram.ajaxRequest("Rebind"); } else if (arg == 'navigateToInserted') ram.ajaxRequest("RebindAndNavigate"); else if (arg.match(/navigateToDeleted.*/)) ram.ajaxRequest(arg);

}

  I am trying to execute the RadAjaxManager ajaxRequest along with the proper argument, but so far all I am getting is an error 'Cannot call method 'ajaxRequest' of null'.  I am able to get reference to the RadAjaxManager object on the page, but the method is not available for referencing at this point.

Any help or comments would be appreciated!

Regards

Hi Telerik,

Are any events fired at the beginning/end of the drawing actions, ideally that can report back to the server in some way? I would like to be able to capture the starting and ending coordinates when a user draws a circle or rectangle using the image editor controls so that I can flag the image as altered when the Apply button is clicked, as well as write it to the database along with an explanation/annotation for explain why it was done (using this for redaction) when the image is saved.

When editing a grid, the pagelayout seems not to work well in edit form templates. I believe it does not account for the space consumed outside of the template, the grid itself and any other space between grid and edge boundary of screen. I have add the pagelayout with in the edit form and also wrap the grid with the pagelayout control. No effect.

Hi,

When using bootstrap, the RadMenu with RepeatColumns = 2 setting renders as single column because bootstrap forces the box-sizing: border-box rule. If we include this CSS rule, the multi-column render correctly:

ul.rmMultiColumn
{
   box-sizing: content-box;
}

Please include the box-sizing rule into the RadMenu out of the box. Thanks,

I have been experimenting with the advanced binding features of the RadTreeView and have hit a wall in my knowledge level. Perhaps one of you can answer it.

I have a simple database schema, as shown in the attached picture.
Manufacturers can have Products which in turn have multiple Parts.

The project contains the Linq to Sql model (also shown)

I am try to have the tree bind the various levels using the RadTreeNodeBinding technique.


with code behind


Only the root nodes of Manufacturer show up, shouldnt it traverse automatically by setting the "DataMember" property to the Property of the LinqToSql Entity that has children entities?

Hi,
After reading posts in different sited for hours, i couldn't find the problem in my code.
I'm using telerik rad chart and need to create a stacked bar chart, according to this data table structure:

Work Week         Product         Quantity
-------------------------------------------------------
201401               a                      10
201401               a                      20
201402               a                       5
201402               b                      10
201402               c                       6
201418               a                      10
201418               b                       25

I know there is a similar question to this, and you referred them to:
 http://www.telerik.com/help/aspnet-ajax/chart-grouping-databound-items.html


but its not helping. 
My code is:

        RadChart1.DataSource = dataForGraph; //dataForGraph is a data table
        RadChart1.DataGroupColumn = "product";
        RadChart1.PlotArea.XAxis.DataLabelsColumn = "WW";
        RadChart1.Legend.Appearance.GroupNameFormat = "#NAME:#VALUE";
        
        RadChart1.DataBind();
        foreach (ChartSeries s in RadChart1.Series)
        {
            s.Type = ChartSeriesType.StackedBar;
        }
And the result is that the quantity is stacked in wrong places (for example quantity 25 is in 201401 instead of 201418)
What am i doing wrong?

Thx,

Hi,

I am working on an ASP.Net Application which uses Telerik Rad Ajax tools in it. We have recently upgraded the Telerik version to the latest Q3 2012 version (2012.3.1308.35) from the Q3 2011 version. After the upgrade, the Image manager tool of the Rad Editor is behaving absurd. Firstly, the Upload and Delete button are not visible at all on the Image Manager window even though no change was made in the code. When I add the UploadPath parameter in the Image Manager declaration code, the button appears but the upload event is not fired on clicking the button. When I right- click on the folder named XYZHandler (where all images are kept) in the window, it gives me options to UPLOAD or RENAME. On selecting Upload, I get the window with Browse and Insert buttons but on selecting a file and uploading, it gives an error stating : File cannot be written to the given target.

Has the way of handling images in the Image manager changed in the latest version ? If so, could you please explain how. If not, what could be causing this issue ?

Please provide me a solution to this.

Thanks & Regards,

Manisha

I would like the Text to contain the combination of the data source's id and name fields.  For example the control:


But in code behind I get an error that source does not have a field 'RemarkCodeID,Name' at the DataBind:

Is there a way I can Implement this?

Hello all,

This is my first post on here so please feel free to point me elsewhere if the information is already on here and I couldn't find it!

Can anybody show me any examples of the RadMediaPlayer out there with the Playlist, the Title bar and the Toolbar showing but without the video content window please?

We're implementing an mp4/WAV audio player in a web app, and it's in quite a narrow portrait format showing the title of the track that's playing, the transport controls and the playlist. However all the demos on the Telerik site are of the video player so we can't see how it might look.

Many thanks!

Donal
