DropDownList is only selecting the default value

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net


The intension is to get the all text file names in the drop down present in a particular location. When a user selects any filename from the drop down, it will show the data which is in that particular text file in a GridView.

I've done both the steps and it's almost complete but i stuck on a small issue. Probably because of non-usage of ASP.NET for a long period of time. The problem is, the drop down only selects the default value not other values.

Here's my code for DropDown Selected Index Change

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
  DirectoryInfo di = new DirectoryInfo(@"C:\myLogs\");
  FileInfo[] fis = di.GetFiles();
  DropDownList1.DataSource = fis;

  string FileName = DropDownList1.SelectedItem.Value.ToString();
  string Path = @"C:\myLogs\" + FileName;
  DataSet ds = GetData(Path);

  GridView1.DataSource = ds;

    private DataSet GetData(string TextFilePath)
      string strLine;
      string[] strArray;

      char[] charArray = new char[] { ',' };
      DataSet ds = new DataSet();

      DataTable dt = ds.Tables.Add("TheData");

      StreamReader sr = new StreamReader(TextFilePath);

      strLine = sr.ReadLine();

DropDownList and TemplateInfo not selecting proper value


I am having trouble with DropDownList (and/or DropDownListFor) when using TemplateInfo's HtmlFieldPrefix in a strongly-typed view.  DropDownList properly selects the value from the model when the prefix hos not been site.  Once I set the value of HtmlFieldPrefix, the value from the model is not selected in the drop-down list.

I am using .NET 3.5SP1 and ASP.NET MVC 2 RC2.


public class TestModel
    public string Text { get; set; }
    public string Option { get; set; }

    public IEnumerable<String> Options
            yield return "One";
            yield return "Two";
            yield return "Three";


public class TestController : Controller
    public ActionResult Test()
        return View(new TestModel

Why won't my Model accept what I'm selecting from the DropDownList?


I edit the Dinner (from the NerdDinner tutorial) and save it, but the Country isn't persisted. Here's my code:


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace NerdDinner.Models
public class DinnerFormViewModel
private static string[] _countries = new[]{

public Dinner Dinner { get; private set; }
public SelectList Countries { get; private set; }

public DinnerFormViewModel(Dinner dinner)
Dinner = dinner;
Countries = new SelectList(_countries, dinner.Country);

Then in my controller I use it like so:
    public ActionResult Edit(int id)
        Dinner dinner = dinnerRepository.GetDinner(id);        

dropdownlist - default value is not 'selected value'

i have created a dropdown list that is populated from a sqlserver datasource. i have a separate sql command which uses the dropdownlist.selected value as a parameter and returns the command value to a label.  it mostly works fine but with one problem. when the page loads, the label value is null, because it doesn't seem to treat the dropdownlist default value as a selected value. when i use the dropdownlist to select a value, this is fine and the label begins to display the expected value. is there anyway I can make the default value when the page is loaded act like a manually selected value, so the label control never displays a null value?

jQuery: Styling DropDownList Alternating Items (Rows)

In the following example, I will show how you can style any asp:dropdownlist very easily.

The example demonstrates how you can change alternating row items background color, using the fadeTo() to add a nice touch in the dropdownlist. You can change alt rows with a couple lines.

ASP.NET DropDownList Web Control, Part 1

Anybody with much experience in ASP has written an include file function for populating the contents of a SELECT dropdown list with entries from a database. Some of the more advanced users have even gone so far as to add caching to their function to reduce database hits for these rarely changing menu options. Naturally, these same techniques are going to be used with ASP.NET, but with a new programming object model. ASP.NET provides a web control, the DropDownList, which can be used for the same purposes as our custom built SELECT tag from Classic ASP.

Declaring a DropDownList in ASP .Net

A DropDownList is also commonly known as combo box. It can contain multiple data members, but unlike a normal list box the users can choose only one value from this control. Though the functionality of this DropDownList is much like a Single Row Select List Box, a DropDownList can save a lot of GUI space as it is rendered on a Single line and is expanded only when the user clicks on the Control

Multiple Column Dropdownlist for the ASP.NET DataGrid

Based on my previous control "Multiple Column DropDownList for ASP.NET", I received many emails asking for the same control to be used in the DataGrid for web applications. Here we go.. This control can be used as the regular MS DropDownList in the DataGrid and also as a regular dropdownlist. It has all the properties, like DataTextField, DataValueField, DataSource, SelectedIndex etc. The download file contains the samples both in VB.NET and C#. In this sample, I have used the Northwind database of SQL Server.

ASP.NET Multiple Selection DropDownList with AJAX HoverMenuExtender

Recently, I was looking for a multiple selection dropdownlist control for my new project. After spending some time researching for it, I decided to put together all my finding in one web user control. This web user control consists of an ASP.NET AJAX HoverMenuExtender, JavaScript, StyleSheet and CheckBoxListExCtrl . The final product will work with or without a MasterPage and you can drag and drop more than one instances of the control on to the page.
