Hello everyone.
Can anyone help me fix this?
Each Telerik Control has multiple entries in the Toolbox - that's just a small portion.
The duplicates all point to the same library.
The Version of each tool is identical to that of its duplicate.
A few times I've uninstalled and reinstalled. Does not fix it.
This problem cannot be fixed with Telerik Toolbox Configurator.
I would appreciate any help or advice you can provide

Thanks all.

Hello,

I am working on the development of an application and I have some doubts in the handling of the PivotFieldList control.

I would like to know how to enter the onclick event of the "Update" button of the PivotFieldList, I want to place some validations when clicking on that button.

I would also like to know how to access the onclick event of the "OK" button that appears in each filter of the fields that are displayed in the PivotGrid, because I also want to add some validations when the button is clicked.

Thanks for the support.

***Updated with Excel spreadsheet (Template.zip) and a simple Project (ReadExcelMap.zip) attachment.

Reference: https://docs.telerik.com/devtools/winforms/knowledge-base/import-data-from-excel

Question: How to get the Cell background color while importing from Excel spreadsheet?

E.g. The spreadsheet below with value and background color.

Import Spreadsheet:

XlsxFormatProvider formatProvider = new XlsxFormatProvider();
            Workbook workbook = formatProvider.Import(File.ReadAllBytes(@"C:\temp\Template.xlsx"));

            var worksheet = workbook.Sheets[0] as Worksheet;
            var table = new DataTable();


            CellSelection selection = worksheet.Cells[3, 25];
            ICellValue value = selection.GetValue().Value;
            CellValueFormat format = selection.GetFormat().Value;
            CellValueFormatResult formatResult = format.GetFormatResult(value);
            string result = formatResult.InfosText;

            IFill f = selection.GetFill().Value;
            ThemableColor c = selection.GetForeColor().Value;

In the ItemCheckedChanged event, I want to also select the item, yet the following assignment returns the error "The property or indexer 'ListViewDataItem.Selected' cannot be used in this context because the set accessor is inaccessible."

e.Item.Selected = true;

How do I do this?

Hello!

The ShapedForm seems to suffer from a few problems:

1. The Shape doesn't honor the Bottom/Top Left/Right Rounded properties at all. No matter what those properties are set to, I always get rounded corners. The attached screenshot should have the top left and bottom left corner rounded only, but shows all corners rounded.

2. When using a border, it is cut off on the right top and right bottom corner (see screenshots). Depending on the border width, it is missing completely.

3. Even when the title bar is removed, the dialog can be moved by the mouse. While this is a handy feature, it also means that double-clicking on the top area of the shaped form will maximize the form and that's definitively not wanted.

Can we expect to have those bugs fixed in the near future since they severely limit the usability of this shaped form.
It simply doesn't look good that way and I'd rather resort to have a form background image with transparency key.

Hi folks!

Just recently I started using Telerik UI for WinForms, but while playing around with the controls to get used to them I found that the RadToggleSwitch doesn't behave like the toggle switches from WinUI/Win10/Win11.

First, the RadToggleSwitch can be activated and the slider can be dragged by using the right mouse button as well. That's not supposed to happen.

Second, the switch sometimes doesn't activate when clicking with the left mouse button. I couldn't find a consistent way to reproduce, though. Only the intermittent observation that the switch didn't change value even though I've clearly clicked inside the button area.

Perhaps a 1 pixel mouse movement between Press and Release will start a drag&drop operation for the slider instead of toggling the value?

Did anyone else experience this behavior?

Cheers

Hello!

When i right left click on a cell (of a radgridview) then right click on the same cell, my custom contextmenu (doesn't need to be custom, i can replicate this exact behaviour on the default one) works as intended. However, when i use the right click first, the contextmenu doesn't work as intended... It shows but if i hover my mouse the items don't get "pre-selected", is as it isn't focused. I already exported the properties of the cell on both situations and the one that doesn't work has fewer properties than the one that works (like 30 or so). So, I'm assuming some information is getting lost on the right click. Is there a way to workaround this? Is it a known bug and can i fix it?

I'm using the assemblies '2020.3.1020.40'.

Thank you for the attention!

I have a radGridView, bound to a datatable with certain columns marked as readonly. The problem is that for the readonly columns, the user can still attempt to edit the cell text/value and only upon leaving the cell are they presented with a message that appears as so.

My goal when clicking on the cell of a readonly column, BeginEdit would not fire (ie, the cursor would not enter the cell). I've tried creating several different events and checking if column is readonly and then cancelling the event but I seem to have no luck.

        private void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
        {
            if (e.Column.ReadOnly)
            {
                e.Cancel = true;
            }
        }
