This is the strangest error, and I can't understand why it's happening, or how to fix it.

I am trying to use the RadSaveFileDialog, and it doesn't appear.

That's it.

The code is stopped at the 'ShowDialog' call, as expected, but no dialog is visible. Because it's inside the Telerik code, I can't see what's causing it to fail.

Does anyone have any ideas where to look to fix this? The old-style SaveFileDialog from Windows works just fine, but it doesn't have all the nice theming that the Telerik one does.

My application uses a global application wide theme via ThemeResolutionService.

I can view my form, buttons, grids etc in the application theme when using the visual studio designer because I load the application theme in the form constructor.

I have a button that will use a different theme called "RedButton". I can force the button to use the different theme at run time via RadThemeManager using:

myButton.ElementTree.EnableApplicationThemeName = False
myButton.ThemeName = "RedButton"

At runtime, I can see my red button. However; in the visual studio designer, the 'red button' is still using the application theme.

I don't see the ability to disable the application theme on my button in the designer.

How can I get the visual studio designer to show my 'red button' while the application theme is also loaded?

Hello,

I have a RadGridView with AutoSizeRows=True.  The last column is a GridViewCommandColumn.   The issue is that I would like the height of the "buttons" in the last column to all be the same height and not vary by row height.  In the example image below, I would like all buttons to be the same height as the button in the first row.

How I would I achieve this?

Thanks,
Todd

Hi,

I'm trying to create a specific chart in RadChartView, where I need to have some annotations which are outside the grid area.  I thought I could extend the axis beyond what is needed and then add the annotations in the space created.   The chart will always have a minimum value of 0, so I extended the axis to -20, which works well to create the space.

However, to make it look correct I need to be able to override the rendering of the axis line, label and grid lines in order to remove the labels for negative values on the axis, and remove the grid and axis lines so the negative space doesn't appear to be part of the chart.  I've managed to do this for the labels, but cannot find an example of overriding the generation of the grid lines or axis line.

Attached is an image of where I am currently at - what I need is to remove all lines on the grid below 0 on the vertical axis.

Has anyone got an example of doing this, or something similar?

Thanks,
Neil.

In my listview the column header text has some space on the left and right side. How can i get rid of this space ?

Hi,

How can I show RadDesktopAlert always on active screen?

Hi,

sorry for a very naïve question :

When using a GridViewCheckBoxColumn with subscription to both ValueChanged events and HeaderCellToggleStateChanged, if I uncheck the header checkbox, the ValueChanged event is fired for each existing (checkbox) row in the gridview.

This is not occuring when the header checkbox is checked (in which case only the HeaderCellToggleStateChanged event occurs).

How can I prevent this behavior (while still allowing two successive events if for example I uncheck the header and just after check a row checkbox).

I probably missed some doc somewhere about this ...

Thanks

I'm trying to bind a set of RadRadioButtons to object properties: Here is the binding:

rbOwnOrRentOwn.DataBindings.Add("IsChecked", prevAddress, nameof(prevAddress.OwnOrRentOwn), false, DataSourceUpdateMode.OnPropertyChanged);

rbOwnOrRentRent.DataBindings.Add("IsChecked", prevAddress, nameof(prevAddress.OwnOrRentRent), false, DataSourceUpdateMode.OnPropertyChanged);

and here are the properties:

        public bool OwnOrRentOwn

        {
            get => _ownOrRentOwn;
            set
            {
                _ownOrRentOwn = value;
                OnPropertyChanged(nameof(OwnOrRentOwn));
            }
        }

        public bool OwnOrRentRent
        {
            get => _ownOrRentRent;
            set
            {
                _ownOrRentRent = value;
                OnPropertyChanged(nameof(OwnOrRentRent));
            }
        }

When I bind like this the object properties are not set when the buttons are selected/deselected.

The docs say that CheckState is one way to go but these enums are defined in System.Windows.Forms. This would mean I need to introduce the System.Windows.Forms into my business layer. Is this what I need to do or is there a better way.

This should be just a simple data binding.

Thanks

Hi,

I have RadGridView with image column? It is possible to filter rows by image?
