Introduction:
Here
I will explain how to display list of files from server folder in asp.net Gridview or get files from folder or directory and bind to Gridview in asp.net using C#, VB.NET.
Description:
In
previous articles I explained 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 display list of files from server folder in asp.net Gridview using C#, VB.NET.
C# Code
string[] filesPath = Directory.GetFiles(Server.MapPath("~/SampleFiles/"));
List<ListItem>
files = new List<ListItem>();
foreach (string path
in filesPath)
{
files.Add(new
ListItem(Path.GetFileName(path)));
}
gvDetails.DataSource = files;
gvDetails.DataBind();
|
VB Code
Dim filesPath As String() = Directory.GetFiles(Server.MapPath("~/SampleFiles/"))
Dim files As New List(Of
ListItem)()
For Each path__1 As String In filesPath
files.Add(New
ListItem(Path.GetFileName(path__1)))
Next
gvDetails.DataSource = files
gvDetails.DataBind()
|
If
you want to check it in complete example write the following code
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Get files from folder & bind to gridview in c#.net</title>
</head>
<body>
<form id="form1"
runat="server">
<div>
<asp:Button ID="btnGetFiles"
Text="Get Files
From Folder" runat="server" onclick="btnGetFiles_Click" />
<asp:GridView ID="gvDetails"
CellPadding="5"
runat="server"
AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="Text" HeaderText="FileName" />
</Columns>
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
</asp:GridView>
</div>
</form>
</body>
</html>
|
Now in code behind add the following namespaces
C#
Code
using System;
using System.Collections.Generic;
using System.IO;
using System.Web.UI.WebControls;
|
Once you add namespaces write the following code in
code behind
// insert files in folder
protected void
btnGetFiles_Click(object sender, EventArgs e)
{
BindGridview();
}
// Bind Data to Gridview
protected void
BindGridview()
{
string[] filesPath = Directory.GetFiles(Server.MapPath("~/SampleFiles/"));
List<ListItem>
files = new List<ListItem>();
foreach (string path
in filesPath)
{
files.Add(new
ListItem(Path.GetFileName(path)));
}
gvDetails.DataSource = files;
gvDetails.DataBind();
}
|
VB.NET
Code
Imports System.Collections.Generic
Imports System.IO
Imports System.Web.UI.WebControls
Partial Class
VBCode1
Inherits System.Web.UI.Page
' 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 filesPath As String() = Directory.GetFiles(Server.MapPath("~/SampleFiles/"))
Dim files As New List(Of
ListItem)()
For Each path__1 As String In filesPath
files.Add(New
ListItem(Path.GetFileName(path__1)))
Next
gvDetails.DataSource = files
gvDetails.DataBind()
End Sub
End Class
