How to create popup window at run time?

[robertaraj]

Hi All,

I am new to vb.net, Can anybody tell how to create a pop up window at runtime. If I have more than 100 product names in the database, While I click the letter 'A' in text box, the window should be open and all the product names starts with letter 'A' should listed in the window in ascending order. (similarly A to Z)

Hi Vidhura,
Above codes are to show one form to another, like link. But I am asking the main form should not hide or close. The window should be opened. (For example you might have seen this in medical shop or library in search of item name or books)

The main form will not be hide or close if you open another form,unless otherwise you specify mainform.hide or mainform.close
you can design the form as like popup window and can show the values.

1.Open new window form.Set the controlbox property to false.Resize the window form as per your requirment.

2.Add label to show the names or texts.Set the Autosize to true

3.Add button control.Add this.close in button click event

Here i m giving sample code

This is the form designer for popup window

namespace TestCombo
{
   partial class Form1
   {
      /// <summary>
      /// Required designer variable.
      /// </summary>
      private System.ComponentModel.IContainer components = null;
 
      /// <summary>
      /// Clean up any resources being used.
      /// </summary>
      /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
      protected override void Dispose(bool disposing)
      {
         if (disposing && (components != null))
         {
            components.Dispose();
         }
         base.Dispose(disposing);
      }
 
      #region Windows Form Designer generated code
 
      /// <summary>
      /// Required method for Designer support - do not modify
      /// the contents of this method with the code editor.
      /// </summary>
      private void InitializeComponent()
      {
         this.btnOK = new System.Windows.Forms.Button();
         this.label1 = new System.Windows.Forms.Label();
         this.SuspendLayout();
         // 
         // btnOK
         // 
         this.btnOK.Location = new System.Drawing.Point(108, 203);
         this.btnOK.Name = "btnOK";
         this.btnOK.Size = new System.Drawing.Size(75, 23);
         this.btnOK.TabIndex = 0;
         this.btnOK.Text = "OK";
         this.btnOK.UseVisualStyleBackColor = true;
         this.btnOK.Click += new System.EventHandler(this.btnOK_Click);
         // 
         // label1
         // 
         this.label1.AutoSize = true;
         this.label1.Location = new System.Drawing.Point(105, 74);
         this.label1.Name = "label1";
         this.label1.Size = new System.Drawing.Size(0, 13);
         this.label1.TabIndex = 1;
         // 
         // Form1
         // 
         this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
         this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
         this.ClientSize = new System.Drawing.Size(261, 266);
         this.ControlBox = false;
         this.Controls.Add(this.label1);
         this.Controls.Add(this.btnOK);
         this.Name = "Form1";
         this.Text = "Form1";
         this.Load += new System.EventHandler(this.Form1_Load);
         this.ResumeLayout(false);
         this.PerformLayout();
 
      }
 
      #endregion
 
      private System.Windows.Forms.Button btnOK;
      private System.Windows.Forms.Label label1;
   }
}
 

This .cs file to write ur methods and events

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
 
namespace TestCombo
{
   public partial class Form1 : Form
   {
      string result;
      public Form1(string str)
      {
         result = str;
         InitializeComponent();
      }
 
      private void btnOK_Click(object sender, EventArgs e)
      {
         this.Close();
      }
 
      private void Form1_Load(object sender, EventArgs e)
      {
         this.label1.Text = result;
      }
   }
}
 
 

The following is the sample code to call this popup window

 private void button1_Click(object sender, EventArgs e)
      {
         Form1 frm = new Form1("Hi this is");
         frm.Show();
 
      }
