Hi Paul, I solved the problem. In the end it was easier.
All columns were set with Frozen = true, so the grid doesn't scroll either horizontally or vertically.

I changed it and now it works the way I want.

Anyway thanks a lot for your attention

Hi Nello

A better solution is thath you set Froze=false for all the columns in the datagridview

In this case both scroll rows of the datagrid are visible and the with of the last column can remain with your original value

Here the result

Hi Nello

When the width of column21 is setted to 100, the vertical scrollbar is showed

The scrollbar is managed internally by wisej using a panel and the cells area for another panel.

And how the with of column21 is too hugh, the scrollbar is hidden

Here an image with this setting and I attach  the sample modyfied

I can, t be able to send by e-mail

i try to attach project with a zip file

Tks

thanks Luca,

The grid is not inside a panel or any other control.

I’m trying t send you my little test project, a zip file of 2,15 Mb, but i get always “forbidden” error.

We are looking to move our Scada HMI from the desktop to the web.

The project is not that simple, so any help will be greatly appreciated.

Hi Nello

Here you can see a video with  a datagrid demo where is loaded with more than 100.000 rows

I used the last dev version 2.2.33

Tell us with version are you using if after the comments of Luca you are still with the error

DataGrid video

Regards and happy coding

Looks like the grid is inside a panel or another container that truncates it. Check the parent control. You can also see which container truncates the gird in chrome with f12. The number of rows or columns doesn’t make any difference.

Don’t use AutoSize on the grid. It makes it grow vertically to fit the rows.

In the designer, when I drag a DateTimePicker, before I can clear the value, but now I get this error “property value is not valid”, the following is the details:

Value of ‘1/1/0001 12:00:00 AM’ is not valid for ‘Value’. ‘Value’ should be between 1/1/1753 12:00:00 AM and 12/31/9998 12:00:00 AM.
Parameter name: Value

And in my code this the error message:

Message = “Nullable object must have a value.”

StackTrace = ”   at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)\r\n   at Wisej.Web.DateTimePicker.set_NullableValue(Nullable`1 value)\r\n   at MainApp.Customers.frmInvoice.frmCustomer_Load(Object sender, EventArgs e) in …..

Thanks.

Hi Stefano,

We’ve finished the enhancement and it will be available for the next build.

We’ve added all the grid line configuration options available here: https://www.chartjs.org/docs/latest/axes/styling.html

Please let me know if you have any questions or issues!

Best,

Levie

For a bound DataGridView with a combo box  column the solution for sorting is to:

1. Add a column to the data source to hold the combo box display value which is populated using the selected value changed event
2. Set sorting for the combo box column to be programmable
3. Hide the display value column and set it to programmable sort.
4. Use the Column click header event to sort the hidden column, but display the sort glyphs on the Combo box column.

This gives the illusion that you are actually sorting the combo box column

Hello.

I’m going to reconsider this question and then
again as another question to support.
I’ll try again.
