In DataGridView there is a row selected and highlighted by default. How can this default selection and highlighting be removed?
I figured it out myself.
After populating the DataGrid, I called the following method:
datagrid.ClearSelection();
I found that faking the prevention of selection worked better for me.

I am using react-table 6.8.6, and I want to disable the checkbox on a specific row with react-table using checkboxHOC. Is that possible?
As mentioned in this GitHub issue, you will have to create your own component for the checkbox. The checkbox HOC is an example and is a fairly short piece of code that was meant to be hacked.
How to do binding for the checkbox? together with the user input if they choose other here? can anyone help?
The simplest implementation will be with Multiselect Widget. However, it will look slightly different:
Model
Designer
Note, strToArray transformer is used in the values binding
Runtime
For sure, you can go fancy customizing look and feel of the Multiselect with CSS or playing with input's visibility basing on selected values and so on...
I'm using ASPxGridView with its default sorting property.
Before, it was not viewing any record after I press to any column name for sorting. But(there's a view all button) after I click to "View all", it was coming in a sorted way.
So I've figured out that I had to Bind grid again if (ASPxGridView1.SortCount == 1).
Now it's working, but only at the beginning, when I click to any column name for sorting, it returns no record, then it works perfectly.
So I need to do something instead of SortCount when the grid loads for the first time.
What could it be?
I do not know your code, but I think that the solution to this issue is discussed in the
Why might paging (sorting, grouping, filtering) not work in the ASPxGridView?
I have an editable datagrid. If sorting is applied by clicking any header of datagrid, it works fine. But after that, if data values are changed in any row of datagrid, sorting is applied automatically. How to prevent from this behaviour? i.e. sorting should only be applied if user clicks on any header of datagrid and sorting should not be applied when user modifies data in grid.
You have to set sortableColumns to false and handle the headerRelease event, where you do the sorting manually on the data source.
<mx:DataGrid sortableColumns="false" headerRelease="onHeaderRelease(event)" ...
just call Object(owner).dataProvider.disableAutoUpdate() before committing the value in your item editor.
I know that you're asking this issue in Flex 4 but I hope the solution that I found in Flex 3 will help.
I also had the same exact problem but then I realized that something in the data must be triggering the sorting to happen.
And it turned out that I was setting the data to be [Bindable]. This made sense to see sorting happened automatically because the value change dispatch propertyChange event.
If you do need to make the data to be [Bindable], use custom binding:

i am using a data grid in flex and i am generating data from a mysql server. However, my problem is with adding a button within the datagrid so each row has one.
i have set the columns itemRenderer to mx.controls.Button although with the buttons shown in the grid there is no label on them (even though one has been set) and the assigned click event does not trigger when hitting the button. anyone have any ideas or guidance on what i am doing wrong.
Thanks
Mark
Not to worry I have sorted it. anyone with a similar issue i suggest reading this
