Importing a document with block-level content controls from XAML causes them to become corrupt. If you scroll to a position in which the said control is only partially visible a NullReferenceException is thrown.
A possible workaround would be to initially save the document as a DOCX (just exporting it to DOCX will not fix the issue as the information is already corrupt).
Setup: In a WPF Windows Desktop application project, use a RadTabControl with 2 tabs, Tab 1 and Tab 2. Add a RadDocking and some Panes to Tab 1.
Run the application and do:
I've attached a sample project showing the problem, with similar instructions as above. Tested with both 2021.3.1123 and 2022.2.622.
Please advice!
private void RadGridView_ColumnReordering(object sender, Telerik.Windows.Controls.ColumnReorderingEventArgs e)
{
int notResizeableColumnIndex = 1;
if (e.NewDisplayIndex == notResizeableColumnIndex)
{
e.Cancel = true;
}
}
Copying content controls using DocumentFragment and then inserting them causes several undesired behaviors.
For example, if the original content control is in "Placeholder mode" (meaning the initial pre-generated text is intact), after the copy operation, its content is treated as user inserted and it is not fully selected on entering the control. Another issue is with Plain Text/Date Picket/Repeating Section control - after the copy, their Properties dialog cannot be shown.
