Hello,
I have an UltraTree which has a view style of OutlookExpress.
I dynamically create the tree and add the nodes to the first UltraTreeNodeColumn I have. That way I have the tree positioned in the left most column of the Grid. This column is defined as follows:
UltraTreeNodeColumn TreeCol = new UltraTreeNodeColumn(); TreeCol = new UltraTreeNodeColumn(); TreeCol.Key = "Tree"; TreeCol.Text = "Tree"; TreeCol.MaxLength = 100; TreeCol.NullText = "NULL"; TreeCol.AutoSizeMode = Infragistics.Win.UltraWinTree.ColumnAutoSizeMode.VisibleNodes; TreeCol.AllowSorting = DefaultableBoolean.True; TreeCol.DataType = typeof(string); ultratree1.ColumnSettings.RootColumnSet.Columns.Add(TreeCol);
As can be seen, the type of data this column receives is a string, i.e. the node's name.
My problem is that I am having trouble displaying an image / icon on the left hand side of the node's name. This feature was possible when the UltraTree was defined as standard for example and then the code below worked:
node.Override.NodeAppearance.Image = _ImageList.Images["img"];
Now that my tree has an OutlookExpress look-and-feel the icons I initially defined do not appear any longer even though the code executes correctly.
What's the best way to add icons to the nodes in the UltraTreeNodeColum?
Thanks.
If you are using OutlookExpress or grid style, then you need to put the image into a cell, rather than on the node. So you could either use the Appearance on the cell of the column you are referring to here or add another column and use that column to display just the image.
Hello !
I found this post as I was looking for how to add images to the left of each tree node in the OutlookExpress style....
Is it really impossible ? Too bad, it would have been great, this feature is really missing, because the OutlookExpress view is very practical for editing attributes of the tree nodes !
Hi Mike,
Can you please give me some sample code to add a image column to the UltraTree when the ViewStyle is OutlookExpress.
Thanks & Regards
