Asked On December 21, 2018 05:12 AM UTC

I am trying to use the borderlayout to place child controls.

Questions I have...

How can I specify what percent of area each child can take, example, one child should take 20% and other 80% and should maintain when resizing the window.
If I have more than 2 children in borderlayout, and want to place them in vertical order, child 1 takes 20%, child 2 takes 20% and child 3 takes remaining and should maintain when resizing the window.

What would be a better layout manager for my needs?

Appreciate any samples.

Hi Farooq Mohammed,

Thank you for contacting Syncfusion support.

We have checked your reported query “how to set the child controls size proportionally” and this can be achieved by SetConstraints method of GridBagLayout control. Also, we have prepared the sample which tries to meet your requirement. In this sample, we have set the Form as ContainerControl of GridBagLayout and adding child controls (like as Button1, Button2, Button3) in Form, then setting the child controls position in virtual grid using the parameters (grid position and cell span) of SetConstraints method. Please make use of the below code example and sample for your reference.

// Need to initialize size for child controls

this.gridBagLayout1.SetPreferredSize(this.button1, new System.Drawing.Size(0, 0));

this.gridBagLayout1.SetPreferredSize(this.button2, new System.Drawing.Size(0, 0));

this.gridBagLayout1.SetPreferredSize(this.button3, new System.Drawing.Size(0, 0));

// borderLayout1

this.gridBagLayout1.ContainerControl = this;

// Set Position of child controls in GridBagLayout

this.gridBagLayout1.SetConstraints(this.button1, new Syncfusion.Windows.Forms.Tools.GridBagConstraints(0, 0, 1, 0, 0.2D, 1D, Syncfusion.Windows.Forms.Tools.AnchorTypes.Center, Syncfusion.Windows.Forms.Tools.FillType.Both, new Syncfusion.Windows.Forms.Tools.Insets(5, 5, 5, 5), 0, 0, false));

this.gridBagLayout1.SetConstraints(this.button2, new Syncfusion.Windows.Forms.Tools.GridBagConstraints(1, 0, 1, 0, 0.2D, 1D, Syncfusion.Windows.Forms.Tools.AnchorTypes.Center, Syncfusion.Windows.Forms.Tools.FillType.Both, new Syncfusion.Windows.Forms.Tools.Insets(5, 5, 5, 5), 0, 0, false));

this.gridBagLayout1.SetConstraints(this.button3, new Syncfusion.Windows.Forms.Tools.GridBagConstraints(2, 0, 3, 0, 0.6D, 1D, Syncfusion.Windows.Forms.Tools.AnchorTypes.Center, Syncfusion.Windows.Forms.Tools.FillType.Both, new Syncfusion.Windows.Forms.Tools.Insets(5, 5, 5, 5), 0, 0, false));
