Our clients can download different product files from their Telerik account:

https://docs.telerik.com/devtools/winforms/installation-and-upgrades/download-product-files 

Currently, when Digitally Signed Assemblies are necessary, they submit support tickets and the support engineers provide the signed assemblies. It would be nice to be directly uploaded to the Telerik account like the rest of the product files.

I downloaded the ERP demo from here: https://www.telerik.com/support/code-library/erp-demo-application-for-winforms

After upgrading the projects to .NET 4.8 and running the application, the following exception is observed:

I'd like to have the merge columns mode, for example like TrueDBGrid (desing time)

It's fantastic, and there is the vertical alignment

I've tried all yours codes to emulate it but it's too slow if radgridview has a lot of rows.

Thanks

Hi Team,

The Travel Assistant demos are broken... it just hangs. This is also true for the Xamarin Demos, WPF demos and WinForms demos.

Here are some screenshots:

UI for Winforms demos

Telerik UI for Xamarin demos

Add a RadTextBox on the form and open its smart tag:

Open the editor for the font and select the entire text:

Then, press Del:

When you try to close the editor, an error occurs:

However, the Font is already serialized as null:

As a result, the designer can't be opened any more:

Just to report a minor typo:

FitlerViewTextCategoryItemCreatedEventArgs, in Telerik.WinControls.UI.FilterView

The designer tries to load the assembly and throws the following error:

This is about this method:

        public void SetError(GridViewCellCancelEventArgs e, Exception exception)
        {
            GridViewDataErrorEventArgs args = new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit);
            if (e != null)
            {
                args = new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);
            }
            this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);

            if (args.ThrowException)
            {
                throw args.Exception;
            }

            if (args.Cancel)
            {
                //TODO: cancel row edit 
            }
        }

The method GridViewTemplate.SetError accepts a parameter of type GridViewCellCancelEventArgs (named e), but uses the information to create a new object of type GridViewDataErrorEventArgs (named args) and uses information from e to fill args.

The method then fires an event with args. Args also has a property Cancel which can be set in the event handlers. But nothing is done with that property.

Parameter e also has a property Cancel which is never be filled. So it could be useful, at the end of SetError, to set e.Cancel with args.Cancel. This way the caller can use the Cancel information from the events.

This request is also related to my next request. 

PS: Why is GridViewCellCancelEventArgs  called this way? It implies it has arguments for an event, but it is not used for an event, am I right?

Hi,

I am using CalHelper to convert recurrence rule to and from string.

It looks like when I convert rule to string and then parse it back to recurrence, some of the properties get dropped.

Please see below from my VS editor highlighting this:

Am I doing something wrong, or is this a bug?

Thanks

The Cut operations of the RadVirtualGrid does not work.

When the SelectionMode is set to FullRowSelect, MultiSelect = true, and multiple rows are selected, the loop goes something like this:

// Pseudo code:
for(int rowIndex = firstRow; rowIndex <= lastRow; rowIndex++)
{
    AddRowToClipboardData(rowIndex)
    UserDeletedRow(rowIndex);
}

1. Lets say 10 rows are selected, only the even rows get copied. First row 0 is copied and deleted. When row 0 is deleted, all rows move a position down. So when copying row 1, it is actually row 2 that is copyied.
2. When cutting all rows, in my case an exception is thrown, because a rowIndex larger than the number of rows is referred to.
3. When cutting to multiple clipboard formats, the second format will not contain the original selected data, because it has already been deleted.

My suggestion:

1. First copy all the data and formats to the clipboard.
2. Then delete the selected rows.

Repro steps:

1. Create a RadVirtualGrid with:
   1. A column with a nullable DateTime
   2. Another column with a string or number.
2. Fill it with one or more rows. The DateTimes remain null.
3. Edit a DateTime cell, open the dropdown:
   
   
4. Click op button [Today], the date/time in the cell changes.
   
5. Click [Tab], the focuses moves to the next cell, but the dropdown remains open:
   
6. Click somewhere else in the grid or form, an Exception is thrown:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.WinControls.UI.RadDateTimePickerCalendar.popupControl_Closing(Object sender, RadPopupClosingEventArgs args)

Expected behavior:

• The dropdown closes after moving to another cell.
• No exception occurs.
