List View failing to draw strings
If you are experiencing issues with the ListView
control in your application failing to draw strings, there could be several reasons for this behavior. Here are some possible solutions to consider:
Check the Control Styles: Ensure that the
ListView
control has the appropriate control styles set for drawing items and sub-items. Set theOwnerDraw
property tofalse
or remove any custom draw settings that might interfere with the default drawing behavior.Verify the Data Source: Check the data source of the
ListView
control to ensure that the strings or text values you want to display are correctly populated. Ensure that the data source is properly bound to the control and that the relevant properties or methods are used to retrieve the text values.Ensure Proper Item Initialization: Make sure that the items in the
ListView
control are initialized correctly with the necessary sub-items. Each item should have the appropriate number of sub-items corresponding to the columns defined in the control. Verify that theText
property of the sub-items is set to the desired string value.Check for Incorrect Column Widths: If the column widths in the
ListView
control are set incorrectly, it might cause the strings to appear truncated or not visible at all. Ensure that the column widths are sufficient to display the entire string content.Check for Overlapping or Hidden Controls: Verify that there are no overlapping or hidden controls on top of the
ListView
control that might prevent the strings from being visible. Ensure that theListView
control is properly placed within its parent container and that no other controls are obscuring it.Handle Custom Draw Events: If you need to customize the drawing behavior of the
ListView
control, ensure that you handle the appropriate events, such asDrawItem
orDrawSubItem
, and implement the necessary logic to correctly draw the strings or perform any custom drawing operations.
