2.You are creating a Windows Form. You add a TableLayoutPanel control named pnlLayout to the form.
You set the properties of pnlLayout so that it will resize with the form.
You need to create a three-column layout that has fixed left and right columns. The fixed columns must
each remain 50 pixels wide when the form is resized. The middle column must fill the remainder of the
form width when the form is resized. You add the three columns in the designer.
Which code segment should you use to format the columns at run time?
A. pnlLayout->ColumnStyles->Clear();
pnlLayout->ColumnStyles->Add(gcnew ColumnStyle(SizeType::Absolute, 50));
pnlLayout->ColumnStyles->Add(gcnew ColumnStyle(SizeType::AutoSize,100));
pnlLayout->ColumnStyles->Add(gcnew ColumnStyle(SizeType::Absolute, 50));
B. pnlLayout->ColumnStyles[0]->Width = 50;
pnlLayout->ColumnStyles[0]->SizeType = SizeType::Absolute;
pnlLayout->ColumnStyles[2]->Width = 50;
pnlLayout->ColumnStyles[2]->SizeType = SizeType::Absolute;
C. pnlLayout->ColumnStyles[0]->Width = 50;
pnlLayout->ColumnStyles[0]->SizeType = SizeType::Absolute;
pnlLayout->ColumnStyles[1]->Width = 100;
pnlLayout->ColumnStyles[1]->SizeType = SizeType::AutoSize;
pnlLayout->ColumnStyles[2]->Width = 50;
pnlLayout->ColumnStyles[2]->SizeType = SizeType::Absolute;
D. pnlLayout->ColumnStyles->Clear();
pnlLayout->ColumnStyles->Add(gcnew ColumnStyle(SizeType::Absolute, 50));
pnlLayout->ColumnStyles->Add(gcnew ColumnStyle(SizeType::Percent,100));
pnlLayout->ColumnStyles->Add(gcnew ColumnStyle(SizeType::Absolute, 50));
