I want to use two comboboxes.
Both combobox data fill from database.

I want second combobox to populate based on selected value from the first combobox.



Please give proper code.

Don't ask for code! Show us what you've done and is not working as expected!

On selectedItemChanged event of the first you load the values of the second combo, using the selectedValue of the first as parameter to your database call.

Ex:


C#
protected void ddlCity_SelectedIndexChanged(object sender, System.EventArgs e)
{
    
        ddlStreet.DataSource = Dal.GetStreetsByCity(ddlCity.SelectedItem.Text);
        ddlStreet.DataTextField = "streetName";
        ddlStreet.DataValueField = "idStreet";
        ddlStreet.DataBind();
        
    }
}

Good Call.

Please don't ask for ready-to-run code.

The ComboBox class has all you need and MSDN provides full documentation (see, for instance, the example in ComboBox Class[^] overview).
