C# Get All Files from Folder and Subfolders & Display it in Gridview in asp.net

By: Suresh Dasari Aug 26, 2013

Introduction:

Here I will explain how to get all files from folder and subfolders in C# and display or bind to Gridview in asp.net using C#, VB.NET or C# Get All Files from Folder and Subfolders and Display it in Gridview in asp.net.

Description:

In previous articles I explained Download files from gridview with link button in asp.net, Upload images to folder and display it in gridview in asp.net, create zip files in asp.net, Delete files from uploaded folder in asp.net, create/delete directory in asp.net, Joins in SQL Server and many articles relating to Gridview, SQL , jQuery , asp.net, C#, VB.NET. Now I will explain how to get all files from folder and subfolders and bind to Gridview in asp.net using C#, VB.NET.

To display all files from folder and subfolders in Gridview we need to write the code like as shown below

C# Code

// Bind Data to Gridview

protected void BindGridview()

{

string strpath = @"E:\Internet Tips\";

string[] folders = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories);

gvDetails.DataSource = folders;

gvDetails.DataBind();

}

VB Code

' Bind Data to Gridview

Protected Sub BindGridview()

Dim strpath As String = "E:\Internet Tips\"

Dim folders As String() = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories)

gvDetails.DataSource = folders

gvDetails.DataBind()

End Sub

If you want to check it in complete example write the following code

<head>

<title>Get files from folder & subfolder & display it in gridview in c#.net</title>

</head>

<body>

<div>

<asp:Button ID="btnGetFiles" Text="Get Files From Folder & Sub Folders" runat="server" onclick="btnGetFiles_Click" />

<asp:GridView ID="gvDetails" CellPadding="5" runat="server">

</asp:GridView>

</div>

</form>

</body>

</html>

Now in code behind add the following namespaces

C# Code

using System;

using System.IO;

Once you add namespaces write the following code in code behind

// Get files in folder

protected void btnGetFiles_Click(object sender, EventArgs e)

{

BindGridview();

}

// Bind Data to Gridview

protected void BindGridview()

{

string strpath = @"E:\Internet Tips\";

string[] folders = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories);

gvDetails.DataSource = folders;

gvDetails.DataBind();

}

VB.NET Code

Imports System.IO

Partial Class VBCode

Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

End Sub

' insert files in folder

Protected Sub btnGetFiles_Click(ByVal sender As Object, ByVal e As EventArgs)

BindGridview()

End Sub

' Bind Data to Gridview

Protected Sub BindGridview()

Dim strpath As String = "E:\Internet Tips\"

Dim folders As String() = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories)

gvDetails.DataSource = folders

gvDetails.DataBind()

End Sub

End Class

Anonymous said...: Hello....

Actually I have a list of items on my html page and i want to bind it with database so that, if i make changes into database items it should reflect immediately to my list items on html page....

I have used DataList yet but it is very heavy control and killing my website performance unnecessarily ....

So, please give me some good ideas.

Thank in Advance; August 29, 2013 at 12:20 AM
