Column width of GridBagLayout sometimes changes when changing the X Fill constraint of a managed control with an X Weight constraint of 1.
I'm using version 19.4.0.52 of the Syncfusion Windows Forms controls in Visual Studio 2022 with a .Net Framework 4.8 project.
I'm using a GridBagLayout to manage the layout of some controls in a panel.
Here's a screenshot of the controls before I set any Fill constraints on any of the TextBox controls.
Setting the Fill constraint on the first two TextBoxes didn't change the column width, but once I set it on the third TextBox, the column width was changed as seen in this screenshot.
I tried working around the issue by setting the horizontal Weight constraints of the TextBoxes to 0 and then back to 1, but it didn't change the size of the first three TextBoxes.
My expectation was that changing the horizontal Fill constraint of the TextBox would change the size of the TextBox within its column in the layout, but would leave the size of the column alone.
I had to modify your sample since the issue only occurs when there are multiple columns in the GridBagLayout.
I've zipped up and attached the sample. When you open it, you'll see it in the same state as the first screenshot below. The second screenshot I took after I selected all the TextBox controls and set their Fill constraints to Horizontal. As I stated previously, my expectation is that the columns will stay the same size and the TextBox controls will expand in width to fill the columns they're in.
The TextBox controls have their WeightX constraints set to 1. All the other controls have their WeightX constraints set to 0.
