How to use tab controls dynamically in c#

Yes. You can do it it.

Create a tab page with no pages in it.

Dynamically create the pages based on the categories.
On the SelectedIndexChanged event of tab, write the code to fill the subcategories.

Following is a sample code. Please create a form and place the Form_Load event as following to run it.

private void Form1_Load(object sender, EventArgs e)

{

TabControl tab = new TabControl();

this.Controls.Add(tab);

tab.SelectedIndexChanged += (object sender2, EventArgs e2) =>

{

tab = (sender2 as TabControl);

TabPage page = tab.TabPages[tab.SelectedIndex];

page.Controls.Clear();

page.Controls.Add(new Label() { Text = "I am sub category of: " + page.Text, AutoSize=true});

};

foreach (string name in new string[] { "Category1", "Category2", "Category3" })

{

TabPage page = new TabPage() { Text = name };

page.Tag = "CategoryIdCanBeStoredHere";

tab.TabPages.Add(page);

}

tab.SelectedIndex = 1;

}
