Is there any update to this?  Does the lastest version have a field resized event to capture?

Regardless of the above (as we do not yet use it) the mention ofPropertyChanged does not work - the event does not fire.

Alex - you have mentioned using an editor style - this would mean having to handle this for all editor types if the dataset is not fixed in it's content, yes?  Seems quite a convoluted solution, just to capture a column resize.  Is there no simple way to do this?

Many thanks

HI,

 You can wire up the  Field's PropertyChanged Event.

 then inside the event  check out the e.propertyname field.

xamDataGrid1.FieldLayouts[0].Fields[0].PropertyChanged +=

new PropertyChangedEventHandler
(MainWindow_PropertyChanged);

void MainWindow_PropertyChanged(object sender, PropertyChangedEventArgs e)

{

//throw new NotImplementedException();

MessageBox
.Show(e.PropertyName);

 You will see LabelWithResolved and CellWidthRsolved names.

 Down side is this might fire often.

 Sincerely.

Hi all.

It is very disappointing that there is no ColumnResized event on the grid.

In my situation, I have a grid with a child record layout, that has to match the parent record layout for usability reasons. This grid is part of the accounting application where each parent row includes totals of the child rows. It is imperative that the column widths of the parent and child rows match exactly. Otherwise, the user will get confused.

Ideally, when a user resizes one of the parent row columns, I would like to resize the corresponding child row column so it always matches the parent row column and vice versa. 

I tried to capture the events suggested earlier in this thread but they fire too often. I feel that handling the PropertyChanged event on the field will impact performance.

What is the best way to request this feature to be added to the grid?

<Style TargetType="{x:Type Editors:ValueEditor}">

<EventSetter Event="SizeChanged" Handler="ValueEditor_SizeChanged"/>

</Style>

Just tried that based on this thread and it didn't work... What am I missing?

Hello,

You can create a Style in the XamDataGrid’s Resources for the LabelPresenter and add an EventSetter for its SizeChanged event like this:

<Style TargetType="{x:Type igDP:LabelPresenter}">
    <EventSetter Event="SizeChanged" Handler="LabelPresenter_SizeChanged"/>
</Style>

Also your event handler in the code behind could look like this:

private void LabelPresenter_SizeChanged(object sender, SizeChangedEventArgs e)
{

}

Hope this helps you.

How do we detect if the user has changed column width?

Is this still not a thing 11 years after the issue has been brought up? I don't think any other Grid on the market is missing this basic functionality.

Also, your voting platform is a mockery, you didn't implement any of the suggestions since its creation. How can you expect users to bother voting?

what do you think money grows on the trees? you can suggest ideas by your self I don't care. we have software to deliver and earn our salaries. no time for suggestions and voting.

I never understood why our technical leaders choose Infragistics anyway....

thanks but no thanks.

Thanks for the standard answer. This was already posted in the forum before. For the paid libraries I expect support stuff actually reads the question .

Hello,

Thank you for your post.

I have been looking into your question and I can suggest using the PropertyChanged event of the Field or the LabelPresenter’s SizeChanged event for detecting the field width change. When you resize a Field, the PropertyChanged event of that Field is fired and the property is LabelWidthResolved. You can use that event to monitor the changes if the Width of a Field. Also you can create a style for the LabelPresenter and add an EventSetter for its SizeChanged event. By doing so, when you resize a field, the event will fire.

Please let me know if you need any further assistance on this matter.
