How to set Text in ComboBox in C#?
In Windows Forms, ComboBox provides two different features in a single control, it means ComboBox works as both TextBox and ListBox. In ComboBox, only one item is displayed at a time and the rest of the items are present in the drop-down menu. You are allowed to add text in your ComboBox by using the Text Property. You can set this property using two different methods:
1. Design-Time: It is the easiest method to set the text in the ComboBox control using the following steps:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the text in the ComboBox programmatically with the help of given syntax:
public override string Text { get; set; }
Here, the value of this property is of System.String type. Following steps are used to set the text in the ComboBox elements:
- Step 1: Create a combobox using the ComboBox() constructor is provided by the ComboBox class.
// Creating ComboBox using ComboBox class
ComboBox mybox = new ComboBox();
- Step 2: After creating ComboBox, set the text in the ComboBox elements.
// Set text in the combobox
mybox.Text = "Rohit";
- Step 3: And last add this combobox control to form using Add() method.
// Add this ComboBox to form
this.Controls.Add(mybox);
Example:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApp14 {
public partial class Form1 : Form {
public Form1()
{
InitializeComponent();
}
private void Form1_Load( object sender, EventArgs e)
{
Label l = new Label();
l.Location = new Point(222, 80);
l.Size = new Size(99, 18);
l.Text = "Enter name" ;
this .Controls.Add(l);
ComboBox mybox = new ComboBox();
mybox.Location = new Point(327, 77);
mybox.Size = new Size(216, 26);
mybox.MaxLength = 3;
mybox.Text = "Rohit" ;
