TableStyle.BeginUpdate() Method
Locks the TableStyle
object. Prevents visual updates until the EndUpdate
method calls.
Namespace: DevExpress.Spreadsheet
Assembly: DevExpress.Spreadsheet.v24.1.Core.dll
NuGet Package: DevExpress.Spreadsheet.Core
Declaration
Remarks
Use the BeginUpdate
and EndUpdate
methods to avoid flickering during batch modifications to the TableStyle
‘s settings. After calling BeginUpdate
, any changes to the TableStyle
‘s settings do not cause immediate repainting. This allows multiple changes without affecting performance or causing screen flickering. Once you finish all desired changes, call EndUpdate
.
The BeginUpdate
and EndUpdate
methods use an internal counter to manage updates. The counter starts at 0. When the counter is above 0, the system blocks visual updates. When the counter returns to 0, the system allows updates. The BeginUpdate
method increments the counter. The EndUpdate
method decrements the counter. If the counter reaches 0, an immediate visual update occurs.
Always pair each BeginUpdate
call with an EndUpdate
call. To ensure EndUpdate
runs even if an exception occurs, use the try...finally
statement.
