<h5 id="GrapeCity_ActiveReports_Design_Designer_LockControls_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>When set to <code>true</code>, this property prevents any modifications to the controls' properties, size, or position within the designer, effectively
making the design surface read-only. This is useful in scenarios where the design of the report is finalized and should not be altered.</p>
</div>
<h5 id="GrapeCity_ActiveReports_Design_Designer_LockControls_examples">Examples</h5>
<p>The sample below opens a Windows Form with the designer, featuring a pre-built report. Users can modify certain properties of existing controls,
but changing the report layout-specifically the position or size of report items-is not possible.</p>
<pre><code class="lang-csharp">class TweakSalesReportForm : Form
{
	public TweakSalesReportForm()
	{
		var designer = new Designer { Dock = DockStyle.Fill };
		var propertyGrid = new PropertyGrid() { Dock = DockStyle.Right };
		designer.LoadReport(new FileInfo("c:\\reports\\Sales.rdlx"));
		designer.PropertyGrid = propertyGrid;
		designer.LockControls = false;
		Controls.Add(designer);
		Contorls.Add(propertyGrid);
	}
}</code></pre>
