Changing the color of a ScatterLine point in Javascript.

Hello

I'd like to be able to change the color of a ScatterSeriesItem point upon clicking. I have tried the following in Javascript; However, it didn't work. I'd appreciate for the help.

function seriesClick(e) {

// change the color of the point to red

e.point.color = "#ff0000";

// redraw the chart

var chart = $find("chart").get_kendoWidget();
chart.redraw();

}

In C#, I am able to change a point's color by ScatterSeriesItem.BackgroundColor property, however I need to be able to do it in Javascript.

Thanks.

Batch Mode Editing Crashing

Hi,

I have a radgrid which contains a template column. Within the Edit template is a dropdown control.

I have the edit mode to set to batch. I then have the client method:

<ClientEvents OnBatchEditCellValueChanged="BatchEditCellValueChanged" />

This triggers the following method:

function BatchEditCellValueChanged(sender, parameters) { sender.get_batchEditingManager().saveAllChanges();}

The problem I have is that when a user makes a change to the dropdown list the page freezes and then it crashes.

If I remove the template column, the editing works fine.

What do I need to do in order for this to work?

Thanks.

Update radgrid with external button (all rows in edit mode)

hi there,
I have some textboxes (for name, surname etc) and and a radgrid on my web page.(for products for example). all radgrid's rows are in "inplace" edit mode.. When I press to external button, form postbacks. meanwhile All information user entered in ragrid get lost. I think I have to update radgrid first but I don't know how ? because there's no update command column in grid. all rows in edit mode and while postingback I need to update all of them at once. How can achieve this ?

Pie Chart Legend Issue

Hi,

When using the pie chart I get very small indicators on the legend - the following code has my database driven pie chart on top and a modified version of the sample below it. The bottom chart shows little square blocks to the left of the legend. The database driven chart on the top shows tiny blocks - you may need to zoom to see them....

I assume this is a bug?

Regards

Jon

DropDownAutoWidth makes the drop down narrower if it's width is smaller than the combobox

First off, I'm ecstatic that this has been developed... a step in the right direction! However, I have one tiny suggestion and it's purely from a UI perspective.

I think if the calculated drop down width is less than the RadComboBox width, it should "default" to the RadComboBox width. If you view my attachment (the too short one), you'll see what happens.

I love that this is done on the client side and would really love to know if there's a work around. Otherwise, I think I'm going to use my "in house" method which is done via server side (and isn't as efficient). This isn't code completely written by me, but I'll post what I currently have in case there are any suggested workarounds or if others are interested.

I have a general utility that calculates the width of text:

public static int TextWidth(string text, string fontName = "Segoe UI", float fontSize = 15)

{

using (var textBitmap = new Bitmap(1, 1))

{

using (var drawGraphics = Graphics.FromImage(textBitmap))

{

using (var drawFont = new System.Drawing.Font(fontName, fontSize, GraphicsUnit.Pixel))

{

return Convert.ToInt32(drawGraphics.MeasureString(text, drawFont).Width);

}

And then I have an extension method:

public static Unit AutoDropDownWidth(this RadComboBox comboBox)

{

var rcbWidth = Utilities.TextWidth(comboBox.Items.OrderByDescending(i => i.Text.Length).Take(1).Select(i => i.Text).First());

return rcbWidth <= comboBox.Width.Value ? comboBox.Width : rcbWidth;

}

So, in my code behind I just have something like:
rcbSalesReps.DropDownWidth = rcbSalesReps.AutoDropDownWidth();

Just something to consider. To me, if I look at the attachments, I think the "just right" version looks much better than the "too short" one.

I'm open to any ideas or suggestions!

Thanks,
Andrew

Image Manager window broken

In the latest build, Telerik.Web.UI is version 2018.2.710.45, the image manager, media manager and few other popup windows open to the right size and then go 100% in hight or more.

Using Chrome, you can see this happening the ribbon sample in the product demos. Go to https://demos.telerik.com/aspnet-ajax/controls/examples/integration/ribbonbarandeditor/defaultcs.aspx?product=editor and then click Insert followed by Image Manager. You will see it open to the correct size and then grow in height when the contents are displayed.

In my project, it grows to 100% with a strange pink striped line at top and bottom, the online product sample goes even bigger than 100% (probably a skin thing).

On every build I get, I check the image manager to see what it is doing this time and if it working right since it gets broken all the time.

Please fix and TEST properly for the next build. I do not look forward to putting out my web app with this defect.

RadConfirm Buttons outside of window

Our application on our development environment is on the latest version of ASP.NET AJAX controls (2018.2.710). Production is on version 2018.2.516.

The RadConfirm OK and CANCEL buttons are outside the window. Please see attached. Is this something wrong in the latest version?
