DataGridView with customized column not showing content initially and on scrolling

0
0

I am using customized data grid column, as per

https://wisej.com/support/question/datagridview-custom-colum-with-3-text-fields#sabai-entity-content-9302

But with Wisej 3.1.8 on both net48 and net6.0 I am having issue that on initial datagrid appearance no content is shown is cells. On scroll some content shows up, but not all grid rows are populated. This worked on on 3.1.2

Assembly info has enabled merge js and css:

// Add the WisejResources attribute to 

// merge js and css embedded resources with the wisej package.

[assembly: Wisej.Core.WisejResources(ExcludeList: “”)]

I am attaching custom renderer as zip file.

Can send you video in PM.

Regards,

D

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
