Resizing Column Widths On Window Resize

1240

Daniel Suitor posted over 16 years ago

I'm trying to resize my column widths whenever the user resizes the window. When the window size changes, I determine the new column widths then apply it to the column and label width properties:

currColField.Settings.CellMinWidth = dWidthPerCol;
currColField.Settings.CellMaxWidth = dWidthPerCol;
currColField.Settings.CellWidth = dWidthPerCol;

currColField.Settings.LabelMaxWidth = dWidthPerCol;
currColField.Settings.LabelMinWidth = dWidthPerCol;
currColField.Settings.LabelWidth = dWidthPerCol;

Problem is, the settings don't take cause the columns to resize. Am I doing something wrong? Is there a better way to approach this?

Thanks
Dan

Hi Dan -

The following code works for me (you would never want to do this but it demonstrates that you can resize cells when the containing window is resized):

protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo)

{

base.OnRenderSizeChanged(sizeInfo);

double newCellWidth = this.xamDataGrid1.DefaultFieldLayout.Fields[0].CellWidthResolved + 1;

this.xamDataGrid1.DefaultFieldLayout.Fields[0].Settings.CellMinWidth = newCellWidth;

this.xamDataGrid1.DefaultFieldLayout.Fields[0].Settings.CellMaxWidth = newCellWidth;

this.xamDataGrid1.DefaultFieldLayout.Fields[0].Settings.CellWidth = newCellWidth;

double newLabelWidth = this.xamDataGrid1.DefaultFieldLayout.Fields[0].LabelWidthResolved + 1;

this.xamDataGrid1.DefaultFieldLayout.Fields[0].Settings.LabelMaxWidth = newLabelWidth;

this.xamDataGrid1.DefaultFieldLayout.Fields[0].Settings.LabelMinWidth = newLabelWidth;

this.xamDataGrid1.DefaultFieldLayout.Fields[0].Settings.LabelWidth = newLabelWidth;

}

Joe,Thanks for the info. I tried to use the code you provided, yet I still get the same results. Perhaps it's the way I'm constructing the grid and the fields. I'm doing it dynamically at run time, not via XAML. I created a sample app using the code you provided that demonstrates what I'm seeing. How can I send you the source to this app so that you can replicate my problem?ThanksDan

Hi Support Team,
I have few columns in XamDataGrid which are able to resize.
I 'm trying set minimum width for each column to prevent from minimizing the entire column.

Thanks in advance!

Joe,I was running against 7.2, but the Beta version. I've since upgraded to the Release version. It took a bit for me to complete this task, hence the reason for my delayed response. This appears to have taken care of it. Thanks for your help on this.Dan

Hi Dan -

When I run your sample app here, the 'Field 1' resizes properly! Are you using the latest 7.2 hotfix version of the controls?
