Hi Jose,

This sounds like a general .NET question. I would suggest you ask about this topic on StackOverflow.

If it works when debugging it must work when deployed. Unless it’s deployed incorrectly. Which is not a wisej issue.

– Follow our deployments steps. Or any aspnet deployment guide anywhere on google.

– It also looks like you recompiled the extension. Try the nuget instead.

– If you still have issues attach a reproducible runnable test case that we can open and run without any additional guessing efforts. Include the exact step you did yo deploy and the full list of files you have deployed with their folders in a txt file.

You can’t set the scroll position. You can scroll a cell or column or row into view.

The HorizontalScroll property doesn’t throw any exception. If it returns null and your code tries to use a null property then normally you get  a null reference exception.

Hi Alaa

I’m trying to sync the scrolling between 2 grids like in https://wisej.com/support/question/datagridview-footer-1, but with the scrollbar at the bottom of both grids (could be the child scrollbar) controlling scroll position of both grids.

In the article Luca states…

“… You could add a second grid to the bottom without the column header and without the vertical scrollbar (see ScrollBars property) and then sync the column resize, move and horizontal scrolling on the client. You can also decide where to show the horizontal scrollbar… ”

I’ve had a look at the sample for that question in which the scroll synching works – parent grid scrolling moves child grid scroll. This I think is due to the child inheriting the parent container (DVG) scrolling (no code used).

I can’t find a way to set a grid’s scrollbar position. DVG has a HorizontalScroll.Value property this throws null exception (HorizontalScroll = null/nothing).

Sample from earlier question attached.

Hi Kingsley,

Would you be able to wrap up a small sample that illustrates the issue?

Best,
Alaa

Thank you, it´s working now.

Hi Kieran,

If you can find a sample online using ChartJS that demonstrates this functionality and provide the source code it can definitely be implemented.
If you would like help implementing it, contact SALES @ WISEJ . COM to get a support package.

Fabio,

your UserControl is missing a constructor. Add this to Page3:

public Page3()
 {
    InitializeComponent();
 }

Jay,

• add a tool to your header cell
• handle the ToolClick event
• iterate through all rows and set the checkbox cell to checked/not checked

Hi Dino,

This looks like an issue with your own custom rendering, not Wisej.NET!

I tried with 3.1.2 as you described, but it also failed to work.

I tried running the old sample from the post you referenced, and from what I can see while debugging your custom renderer that there’s an issue with the logic, because the JSON that you’re trying to parse isn’t actually an array, and thus the length property is always undefined.

Check your developer console and you’ll see the “Cannot read properties of undefined (reading ‘V’)” error popup!

So, unless you have modified that sample with other data, I’m afraid that this is not a Wisej.NET issue, but you can always attach it for us to check!

Best,
Alaa

Hi Helen,

we can´t tell what might be going wrong just from a screenshot.
Please provide us with a compilable testcase and we can try to track it down.

You can easily build a custom drop down control containing other controls. There are many ways to do that: flex panel, panel, data repeater, etc.

Contact our support directly and include your license information and detailed requirements if you need further assistance on how to create a list of controls in C# or VB.NET.

Hi Alaa,

I already have libgdiplus installed.

Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
libgdiplus is already the newest version (6.0.4+dfsg-2).

Best regards
