Adjust the height of Report viewer toolbar in windows form

I am using report viewer inside a windows form and I am trying to adjust the height of the ToolStrip of the ReportViewer.

I tried to adjust the AutoSize property to false then adjust the Height but the height didn’t change:

var toolStrip = (ToolStrip)reportViewer1.Controls.Find("toolStrip1", true).First();
toolStrip.AutoSize = false;
toolStrip.Height = 100;

How can I adjust the height of Report viewer toolbar in windows form? Any suggestions would be much appreciated.

Solution

  • The ToolStrip of the report viewer has Dock = Fill inside a custom control (report toolbar). The report toolbar has overridden is size-related methods and properties and looks into the PreferredSize of the ToolStrip to set the bounds.

    Properties like Padding, ImageScalingSize, MinimumSize, Font contribute to determining the preferred size of toolstrip; so you can set either of mentioned properties.

    The most effective property is MinimumSize:

    var toolStrip = (ToolStrip)reportViewer1.Controls.Find("toolStrip1", true).First();
toolStrip.MinimumSize = new Size(0, 100);
toolStrip.Parent.Height = 0; // No effect, just to force recalculation of height.
