Event Data

The CustomColumnDisplayText event's data class is TreeListCustomColumnDisplayTextEventArgs. The following properties provide information specific to this event:

Property Description
Column Gets the column which owns the processed cell.
DisplayText Gets or sets the display text for the cell currently being processed.
Node Gets the node which owns the processed cell.
ShowAsNullText Specifies whether text corresponding to a null value appears faded.
Value Gets the processed cell’s value.


The CustomColumnDisplayText event occurs for bound and unbound columns. The printed GridControl also displays customized text.

If you want to maintain a clean MVVM pattern and customize a data cell’s display text in a View Model, create a command and bind it to the CustomColumnDisplayTextCommand property.

The TreeListCustomColumnDisplayTextEventArgs.DisplayText property contains a cell’s display text. To customize the display text, assign a string value to this property.

<dxg:TreeListColumn FieldName="Value"/> 
void treeList_CustomColumnDisplayText(object sender, TreeListCustomColumnDisplayTextEventArgs e) {
    if (e.Column.FieldName == "Value")
        e.DisplayText = string.Format("{0:n2}", e.Value);
