Hi,

I'm playing around with DPI awareness. Most things scale as expected (the grid for example) but it seems to me that the Treeview does not size the items according to the Font (the font scales as I would expect but gets truncated, the height of the listitems seems to be unchanged). What am I missing?

Regards

Erwin

I have just downloaded the WinForms UI (30 Day Free Trial) and have been experimenting with the Carousel.  First, I want to use a background image in the Carousel or the Form; how do I turn off the gradient used in the carousel.  I tried setting backcolor to transparent with no effect.

Second, I would like to create the same layout used in one of the Telerik Demos (See attached image).  How can I accomplish this?

Last, I am using Visual Studio 2015 and I am unable to open many of the downloadable demos...including the demo for the Carousel!!!  I have spent a frustrating three hours trying to adjust settings without the correct results.

I'm not sure I want to invest in a package without available help.  I was able to view some Carousel videos on YouTube, however the information I was looking for was not mentioned.  Please help.

Dave

Hi,
I need to create a custom user control which contains a grid and some other components, the grid is a public property of the panel.
When i drop the panel on the form and use the grid property to create columns everything is fine, but suddenly i realized the form is not generating added column's code in designer.cs, and after build there is no column left in my grid.
So, my question is how can i force form to generate the columns code?
Tnx

Hello,

I was wondering if it is possible to use the Context Menu on a Line series radchartview? I want to be able to right click on a Line series within the chart and open up a context menu that corresponds to that line and I also want to be able to do the same thing on the legend except with a separate context menu.

Any ideas?

 

Thank you,

Hi,

Aft

After experiencing a crash when pressing any alpha-numeric key on a cell containing a VirtualGridDropDownListEditor, I spotted an error in Telerik source code at file RadGridView\VirtualGrid\Input\VirtualGridInputBehavior.cs (around line 1441) :

protected virtual bool HandleAlphaNumericKey(KeyPressEventArgs keys)
{
 
    ...
 
    else if (this.GridElement.ActiveEditor is VirtualGridDropDownListEditor)
    {
        string symbol = keys.KeyChar.ToString();
        RadDropDownListEditor editor = this.GridElement.ActiveEditor as RadDropDownListEditor;
        RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;
 
        if ((element.AutoCompleteMode & AutoCompleteMode.Append) == AutoCompleteMode.Append)
        {
         
            ...

 

The editor variable should be cast as VirtualGridDropDownListEditor

Just to let you know for next releases
Sorry if bug has already been spotted and fixed :)

Regards

Hi

I'd like to add custom rows that have a single button on them. I've managed to get a custom row with a button showing instead of the new row as per your documentation, but I'd like to get it showing elsewhere. My grid is not data bound - I'm programatically adding rows to it and I'd like to programatically add the custom row at certain positions. My grid includes a single level of grouping, so I'd need to be able to add the row to a specified group. I'd also like to be able to use different button text in some cases and to pass the button click event up to the form that the grid is on. How do I do this?

Thanks

Hi,

I was wondering if there is a way to use tooltips on a line series instead of a trackball. For example if i clicked on a certain line series in a multiline series chart, the information for that point of the line series would be displayed to the user? 

Thank you.

I've got a few RadDateTimePickers which are all bound to various data sources. Some of them have a null value, some have values, which all display fine - however the issue I am having is that when you click the field to select a date, the default date that is selected is from when I added the control to the form.

 

This should be today's date, however the value of the field should remain null until the user has clicked a date. They do need to be able to select a date in the past/future though as well.

 

I'm using the latest version of Telerik UI for WinForms on a VB.net project.

 

Any help would be much appreciated.

 

Thanks, Shane

Hi, basically I want to simulate the Shift + click to sort multiple columns. For example, if the user click on Column A to do an ascending sort, I want to also sort Column B ascending.
I added the sort descriptors in the designer and it works on startup, but as soon I click on Column A or B, the original sort descriptors are lost.
Any suggestions?

Thanks,
Andy

How to make it to catch ChartViewSelectedChanged event? Seems to work for other chart types such as cartesian or pie..

public Form1()
{
    InitializeComponent();
 
    radChartView1.Controllers.Add(new ChartSelectionController());
    radChartView1.SelectionMode = ChartSelectionMode.MultipleDataPoints;
    radChartView1.SelectedPointChanged += new ChartViewSelectedChangedEventHandler(OnChartSelectedPointChanged);
}
 
private void OnChartSelectedPointChanged(object sender, ChartViewSelectedPointChangedEventArgs e)
{
    PolarDataPoint pt = e.NewSelectedPoint as PolarDataPoint;
    if (pt == null) return;
    System.Diagnostics.Debug.WriteLine(" angle = " + pt.Angle + " value = " + pt.Value);
}
