UltraTreeNodeColumn.LayoutInfo.OriginX property units
posted

What units does the UltraTreeNodeColumn.LayoutInfo.OriginX property represent? And what are the units relative to?

The description states it is the X coordinate in the virtual grid. What is the virtual grid?

I am adding a checkbox column and image column to a databound grid. I set the OriginX property to 0 for the checkbox because I would like it to be the first column. And, I set the OriginX property to 1 for the image column because I would like it to be the second column. Well, the checkbox is the first column, but now the image is below the checkbox?

I had to set the OriginX property to 2 for the image column to make it appear as the second column. Why?

Here is a snipit of code:

private void treeHierarchy_ColumnSetGenerated(object sender, ColumnSetGeneratedEventArgs e)
{

UltraTreeNodeColumn colCheck = new UltraTreeNodeColumn();
colCheck.LayoutInfo.OriginX = 0;
e.ColumnSet.Columns.Add(colCheck);


UltraTreeNodeColumn colImage = new UltraTreeNodeColumn();
colImage.LayoutInfo.OriginX = 2;
e.ColumnSet.Columns.Add(colImage);

}

    The units are logical columns. The logical columns are created by the layout as a whole and are calculated based on the items within the layout.

    I'm probably not describing it very well. The RowLayouts use a concept called a GridBagLayout. I'm sure if you do a search on the internet there are web sites out there that describe GridBagLayouts better than I can.

    Probably because the default SpanX of every column is 2 by default. The default is 2, because otherwise, if you changed the LabelPosition to Left or Right, the cell contents would disapear.
