RadCheckBoxEditor ThreeState not maintaining Indeterminate when displaying the check box

I have a WinControl RadGridView that is not data-bound to any dataset, we manually create the rows and need be based on certain criteria at the time of load. Clicking into specfic cell, the EditorRequired event get fired where depending on which row we are working with we will present a custom control to fit the needs for that row.

For one of the conditions we are adding a RadCheckBoxEditor to the cell with ThreeState set to true.

Values are getting sent back to the grid row correctly for all three states, but when we try to load the editor again, when it trying to load an Indeterminate the check box always renders as off.

Following the ValueChanged and ValueChanging events; ValueChanged is coming in as Indeterminate, but ValueChanging is showing as false for the new value. This is before any user interaction.

Is there anyway for the checkbox to paint as the "Indeterminate" state.

Thank you

Get appointment by UniqueID property

Hi all,
I implemented RadScheduler component into external app (Dynamics NAV) as .NET add-in. Appointments which are created inside RadScheduler component are correctly transferred to Dynamics NAV (via XML). Then I run some business logic inside Dynamics NAV in order to save these appointments into Dynamics NAV database. Everything works correctly if there are no warning or errors in Dynamics NAV. But sometimes the business logic in Dynamics NAV produces an error -> appointment in Dynamics NAV is not created and in that case I need to delete this appointment in RadScheduler component as well. And in that case it would be nice, e.g. I will be able to get appointment by UniqueID property or something like that in order to remove this appointment from RadScheduler component as well. Can you help me how can I do that? Thanks in advance.

RadDropDownList Designer item Selected dosent work

Hi.

Im not sure about if anyone was already reported it, but, when i add some items to RadDropDownList and when i set "Selected" Property to one of them and i accept the changes the "Selected" property is deleted. I'm using Telerik UI For WinForms Q1 2016 SP1.

I solved this issue establishing directly the property in the designer file just like this:

//

// radDropDownList2

//

this.radDropDownList2.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

radListDataItem1.Text = "--Seleccione--";

radListDataItem1.Selected = true;

radListDataItem2.Text = "Masculino";

radListDataItem3.Text = "Femenino";

this.radDropDownList2.Items.Add(radListDataItem1);

this.radDropDownList2.Items.Add(radListDataItem2);

this.radDropDownList2.Items.Add(radListDataItem3);

this.radDropDownList2.Location = new System.Drawing.Point(115, 356);

this.radDropDownList2.Name = "radDropDownList2";

this.radDropDownList2.Size = new System.Drawing.Size(125, 20);

this.radDropDownList2.TabIndex = 29;

Drag row from grid to control on another form

Hi,

As a topic, I would like to do drag & drop a row from the grid to the RadListView control placed on a different form.

I am using CustomRowGridBehavior+RadDragDropService on grid form side like here:

http://docs.telerik.com/devtools/winforms/listview/drag-and-drop/drag-and-drop-using-raddragdropservice

The problem is, that this solution does not trigger DragEnter event on RadListView.

There is a small project sample in DragFromGridToAnotherForm.gif.

Just change extensions to .zip

Any way to set the width of bars individually?

Are there any properties on a BarPointElement, for example, that I can use to set the width of any given bar in a series separately from the others?

I already know how to get to the the point element to do formatting, just don't know what to set to get what I want. Kind of like the gap with but individually, not for the whole axis...
