I want to use a RadTreeListView but the hierarchy does not contain children of the same type. Can I achieve this using RadTreeListView and have different properties at each hierarchy level?

Thank you!

Hello,

I found row-height setting API in WinForms, like Resizing Rows Programmatically- RadVirtualGrid - Telerik UI for WinForms .

But can't find it for WPF. I can make rows resizable by a user but can't do it programatically.

What I'd like to do is to control row height per cell content height.

Thanks.

Hello, 

I am using a RadTreeView component in a WPF application that looks like in the following photo. The hierarchy is: a Category can contain a list of SubCategories and a SubCategory contains a List of Activities that have some properties. I would like to transform my RadTreeView into a RadTreeListView or RadGridVew in order to beneficiate from SelectionUnit property and the navigation between cells from the keyboard but I could not find anything that meets by needs:

a component with cells only on the last level of the hierarchy, to be able to select a cell and edit it  and, if possible, to have a tabular header with details from the last level of the hirarchy.

Thank you!

Hi,

I am working with RadGridView of Telerik

Source of the RadGridView is QueryableCollectionView (with OData)

Each column has filter option.

but the filter popup advance contains only "Select All" and not all the values of the column.

What should I do for see all the values in the filter advance?

Thanks

In my code I have a implemented method which in some cases can append new text for existing archive entry. But when I tried this code it gives me a System.ArgumentException: 'An item with the same key has already been added. Key: dir/file.csv'. This exception occurs in situations when given entryName will be something like this 'dir//file.csv''.  This small difference does not allow archive.GetEntry(entryName) return something else then null.

public void Insert(Stream stream, string entryName, bool append = false)
{
    using var baseStream = FileSystem.FileStream.New(ArchivePath, FileMode.Open, FileAccess.ReadWrite);
    using var archive = new ZipArchive(baseStream, ZipArchiveMode.Update, false, null, compressionSettings, encryptionSettings);

    var entry = archive.GetEntry(entryName); // null
    var entryStream = append
        ? entry?.Open() ?? archive.CreateEntry(entryName).Open() //exception cause already exists
        : archive.CreateEntry(entryName).Open(); 
    stream.Position = 0;
    if (append) entryStream.Seek(0, SeekOrigin.End);
    stream.CopyTo(entryStream);
    entryStream.Flush();
}

I am learning game programming  in C# with WPF using MSVS-2022.

 For this MSVS-2022 offers two types of project:

I googles these and still cannot figure out what is the difference - they both are for WPF application,

Which one is more suitable for game programming?

And will the code written using WPF Application  - could it be copied to a WPF App (.NET Framework) and run without corrections?

Hello everyone,

on my WPF application I have to use a WizardPages component to make a configuration. These configuration (and the relative pages) may changes based on a combobox item selectable on the first WizardPage (a page in common for all configurations).

My question is.... It's possible to add WizardPages dynamically based on the selection on the combobox of first page?

Thank you

Hi, we have implemented the ExportToXlsx method and it worked really well out the box.. however we are utilising the paging method (also the group before paging too) and would like the export to give us all the data returned - this is present in the dataset, so no additional call is needed to get more pages.

Any assistance would be great.
