Good evening, I have a small inconvenience, I want to show a vertical line in the highest value of the chart, but when I try to do it, it shows the line vertically. Any suggestions? Thanks.

this code:

 var max_linea = listaDatos.Max();
            var min_linea = listaDatos.Min();
            var posicion = listaDatos.IndexOf(listaDatos.Max());

          

            CartesianGridLineAnnotation annotation1 = new CartesianGridLineAnnotation();
            annotation1.Axis = this.ChartSuspension.Axes[1] as CartesianAxis;
            annotation1.Value = max_linea;
            annotation1.BorderColor = Color.Red;
            annotation1.BorderDashStyle = DashStyle.Solid;
            annotation1.BorderWidth = 1;
            this.ChartSuspension.Annotations.Add(annotation1);
            CartesianGridLineAnnotation annotation2 = new CartesianGridLineAnnotation();
            annotation2.Axis = this.ChartSuspension.Axes[0] as CartesianAxis;
            annotation2.Value = posicion;
            annotation2.BorderColor = Color.Blue;
            annotation2.BorderDashStyle = DashStyle.Solid;
            annotation2.BorderWidth = 1;
            this.ChartSuspension.Annotations.Add(annotation2);

     I am able to use the bindinglist() as a datasource for my winforms gridview. I set a timer to randomly update an item in my binding list and the changes are correctly reflecting on the grid. I am using the Onpropertychanged and iNotifyPropertyChanged events in my data class, so my grid is updating with the correct values when the underlying data changes.

I would like to make the cell momentarily change color when the data is changed in that cell. 

Is there a grid event that fires when the underlying data changes when using a bindinglist and the onpropertychanged notifiers?

I cannot seem to locate the correct grid event that fires when the data changes.

Hello,

So, I have a SplitContainer which contains checkboxes and stuff whose Enabled and Checked statuses will determine what Values will be written on the Database.
When the process to write to the DB begins, I make the Splitcontainer.Enabled = False so that the user will not change anything after the Submit button has already been pressed.
I notice that even though the togglebutton's enabled status is True, when its parent, the Splitcontainer has Enabled=False, the togglebutton itself goes to Enabled=False.
I didn't programme such behaviour, so am I right to assume that this is something that happens by default on Telerik controls?

If so, is there a way to globally disable it? On the normal Windows Forms Controls this doesn't exist and I am used to leveraging this behaviour.

Hi!

Can you please tell me how can I change the background color of dropdown list item with SetThemeValueOverride when the item is in mouseOver state?

And how can I identify the elements, primitives, properties in every case if I need to change something with SetThemeValueOverride? Is there a generic guideline?

Until now I used your Visual Style Builder, but in some specific cases it doesn't help.

e.g.: DropDownList has a ListView, but how can I access ListItems and their states (default, mouseOver, Disabled etc.) through the DropDownList element?

Thank you,
Sandor

Hi,

My start time is 01/03/2018, and my end time in 09/02/2019.

I would like to zoom in the time line so that I can see all the tasks within one page, is that possible?

Hi,

Is it possible to make the GanttView read only, that is no update is allowed.

Also, is it possible to make the left side panel fixed?
