Setting column width after grid has loaded

How can I set the width of a column after my grid has already been loaded? (seems like such a simple task but I can't seem to get it...)

Example: Program is running, user performs some action, I want to resize one or more columns.

Thank you,
Mike

I would also like to know how to do this in code.

In my case, if the user has adjusted the column widths, I want to save the widths when the form is closing and set them the next time they open the form.

I have tryed setting the CellWidth and ColumnWidth but they don't seem to make any difference.

Hi Ron/Mike -

You will need to set both the LabelWidth and CellWidth properties on the FieldSettings object to force the column to be a particluar width.

However, there is a problem in the current 7.1 and 7.2 releases: while the above settings will take effect if you set them before the user interacts with the grid, once the user has resized a column in the UI, any subsequent settings you make to the above 2 properties are ignored. This is a bug in the 7.1 and 7.2 releases which has been addressed in the next hot fix which will be available late this week or early next week.

Hi Ron -

The 7.1 and 7.2 hotfix releases were original scheduled to be publicly posted this past monday. Unfortunately this has been delayed until next friday April 4 for reasons I don't quite understand. The hotfix builds are completed, and as far as I know no issues have been raised during customer a private customer review process. I am pushing to get these released ASAP - I will post a message to all here when the builds are available.

Hi,
Has this been resolved? I am using v8.1and cannot make it work.
I have 2 grids and when a user resizes a column width on one grid, I want to set the column width on the other grid to match. I have a routine that should work, but nothing gets changed. I have something like this that I fire after a CellWidthResolved property has changed. Unfortunately, it has to set every field every time a column width is adjusted, but it does not happen that often and at least they should stay in synch this way.

                foreach (Field fieldMaster in grid1.FieldLayouts[0].Fields)
                {
                        foreach (Field fieldServant in grid2.FieldLayouts[0].Fields)
                        {
                            if (fieldMaster.Name == fieldServant.Name)
                            {
                                fieldServant.Settings.CellWidth = fieldMaster.Settings.CellWidth ;
                                fieldServant.Settings.LabelWidth = fieldMaster.Settings.LabelWidth ;
                            }
                        }
                 }

      Aside from the unusual circumstance, is there something obvious I'm doing wrong here?

Rather than using an event I have synchronised the widths of the columns of a Master and Details grid by binding the Details grid Field Width to the CellResolvedWidth of the corresponding Master Field:

foreach(var field in _myDataGrid.FieldLayouts[1].Fields)
{
var b = new Binding("CellWidthResolved");
b.Source = _myDataGrid.FieldLayouts[0].Fields[fieldName];
BindingOperations.SetBinding(field, Field.WidthProperty, b);

}

This seems to work nicely.
