Hi,

Using the last release of RadSpreadsheet, I get an exception when the first row is hidden when scrolling with the mousewheel. Attached is a demo.

Thanks,

Megan

Release R1 2020

Please follow the steps:

1. Run the attached sample project. 

2. Move the form to a monitor with 125% DPI scaling.

3. Resize the form to make the spreadsheet bigger. You will notice that the column/row headers are missing for the last column/row headers.

The UI behaivor of drag selection shows inconsistent behavior between WinForm vs WPF/Excel.

When you drag some cells for selection and keep dragging to the right (getting the out scope), the control scrolls to the right.

This behavior is common in Winform/WPF/Excel.

When you drag backward (to the left), WPF controls scroll back and so is Excel, while Winform controls does not scroll

Same thing for top and bottom scroll. Winform Spreadsheet control does not scroll. It may scrolls only to the right.

Another Caveat I see meanwhile is that when you scroll backwards until the row area, the pointer become row-resize pointer, or so

If you keep mouse moving around, it sometimes makes a horizontal line (possibly a guide for row resize?)

The issue in this case is that, it does not remove itself. the horizontal line stays there. It is not very annoying (as it is thin horizontal line) but is still a bug.

 

To reproduce,

create a empty Winform app, with the RadSpreadsheet Control, and Run

Drag from row C3 and to the right (around the scrollbar) the control scrolls to the right (this is not quite smooth though..)

Scroll right to AZ3 say, and drag backward back to C3, this now does not scroll back.

Same for top and bottom.

Do the same for WPF, it now works as expected

Do the same for MS Excel, it now works as expected.

Currently if radSpreadsheet RightToLeft property is set to Yes, only the Formula Bar is affected; RadSpreadSheet and Status Bar are not.

Release R1 2020 (LIB 2019.3.1111)

Add a RadSpreadsheet on the form and try resizing it at design time. You will notice that the control is resized after a considerable delay.

If you Dock the control to Fill and try resizing the form at run you will notice that the layout is incorrect. The attached gif file illustrates the obtained behavior.

Workaround: update the layout after resizing:

        public RadForm1()
        {
            InitializeComponent();
            this.radSpreadsheet1.SizeChanged+=radSpreadsheet1_SizeChanged;
        }

        private void radSpreadsheet1_SizeChanged(object sender, EventArgs e)
        {
            this.radSpreadsheet1.SpreadsheetElement.InvalidateMeasure(true);
            this.radSpreadsheet1.SpreadsheetElement.UpdateLayout();
        }

I have implemented the ListDataValidationRule code to add a dropdownlist to the spreadsheet. Based on the code I can find and the searching I have conducted, it seems to be correct, however the dropdown does not appear in the control.

The dropdown list does appear in Excel when I export the file.

 

Dim Context As ListDataValidationRuleContext = New ListDataValidationRuleContext(CurrentWorksheet, CurrentCellIndex)

Context.InputMessageTitle = "Restricted input"
Context.InputMessageContent = "The input is restricted to the week days."
Context.ErrorStyle = ErrorStyle.Stop
Context.ErrorAlertTitle = "Invalid Bedroom Type"
Context.ErrorAlertContent = "The entered value is not valid."
Context.InCellDropdown = True

Context.Argument1 = String.Join(",", _Data.ArchitectCert_UnitBedrooms.AsEnumerable().Select(Function(x) x.Field(Of Integer)("UnitBedroomNumber").ToString()).ToArray())


Dim Rule As ListDataValidationRule = New ListDataValidationRule(Context)

CurrentWorksheet.Cells(CurrentCellIndex).SetDataValidationRule(Rule)

When you set the AutoSize property to true, the control becomes enormous - Size (5002, 5002).

There is no specific logic for auto-sizing the control. We should either remove the AutoSize property or size the control according to the rows/columns it uses.

Release R3 2019 (LIB 2019.2.819)
Please run the attached sample and move the spreadsheet on a monitor with 125% DPI scaling. Then, enter some text in the first cell that exceeds the column's width and double-click the header to best-fit the column. You will notice that RadSpreadsheet hangs and it is not possible to proceed with the further execution of the form.

The scale factor is not imported from documents with no information about the selection state.

Release R2 2019 SP1
The data validation rule should have values for formula1 and formula2 elements, which define the start and end values for a range to validate between. When such values are missing, a NullReferenceException is thrown on import and the document cannot be imported. As a workaround, the document can be modified by deleting the AlternateContent attribute.

I have loaded an excel file into the spreadsheet control from our document database. When a user makes changes and clicks the save button I would like to handle a save process back to our document database of the file.

If a save function can be raised I can save to the document database

If a SavAs fucntion can be raised I can prompt the user to create a new version

 

Can the control have these two features added please?

For some reason the last letters are dropping from headers and data.

If the lookup_value parameter and lookup_vector parameters refer cells containing text values, the function returns a Not available error ("#N/A").

If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.

Hello,

 

So here's what happens. I create a workbook and a worksheet in that wb which I assign as the workbook of a RadSpreadSheet by RadSpreadSheet..Workbook = wb

The first time I assign a name to the first (and only sheet) created in the creation of the wb, the name does appear on that sheet.

Then some code takes this workbook ByVal, creates a new Sheet, makes that sheet the wb's ActiveWorksheet and then changes the ws's name.

You can see in the debugging that the worksheet does have the new name i put there ("2018-05"), but visually this 2nd worksheet has the default name "sheet 2".

Then that wb which is returned by the function is assigned as the RadSpreadSheet's workbook

If I run the code again, so a 3rd sheet is created, then the 3rd sheet will visually have the default name "sheet 3", however in the debugger it says "2018-06" as its name; but most importantly, now sheet 2 has magically changed to what I was seeing its name to be in the debugger ("2018-05").

 

I'm assuming that If I'm changing the sheet names at runtime, I need to call some method on the Workbook element or something like that in order to update the names. I just couldn't find which method to call.

 

Best regards,

Ioannis Mamalikidis.

Hello,

 

So, I'm testing the Telerik suite, part of which is the RadSpreadSheet. I'm currently using the 30 days trial.

So, when I'm debugging it and I'm instantiating a new form that contains the RadSpreadSheet, the programme will about 50% of the time create an exception of object reference not set to an instance of an object
Now, I've only noticed this with forms that contain a radspreadsheet but it could have nothing to do with it.

What always happens before I get the exception is that the reminder to buy a Telerik License appears (the programme halts until I choose an option) and when the dialogue disappears, the exception happens.

 

Please note that if I just push "F5" again in VS, without changing anything anywhere, so after the crash immediately debug (F5) again, the exception will not occur.
