Add the rule from this article and observe the result: Data Validation
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.
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.
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.
please try set the WorkBook to RadSpreadsheet.
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()
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)
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.
Add support for creating Tables and applying tables styles (predefined ones or custom).
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?
To reproduce: - Open the first look example. - Choose Save from the backstage button. - Currently, the default is PDF, It should be xlsx.
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.
