I can't run on IIS Server. I write with dynamically create link button in gridvew row data bound and Link button can't redirect access to file server. I only can on visual studio. Please let me know, how to solve it.

Im totally new to ASP so any help would be very grateful. I have a html page which has a form for users to leave their details and when they submit it goes to a text file fine but what I want is once they have submitted it I want to have an alert saying "comment saved" and to stay on the original page so they can submit another if they choose but when the user submits it goes to a blank page.
My Form is
<form method="post" action="comments.asp">
<br><br>
Age <input type="text" name="age" />
Name<textarea rows="1" cols="70" <input type="text" name="name" /></textarea>
<input type="submit" value="Send Comment">
</form>
my comments.asp file code is
<%
Dim age, name
age = Request.Form("age")
name = Request.Form("name")
dim fs,f
set fs=Server.CreateObject("Scripting.FileSystemObject")
set f=fs.OpenTextFile("C:\Inetpub\wwwroot\Wiki\Comments.txt",8,true)
f.WriteLine(age & " " & date() & " " & name)
f.Close
set f=nothing
set fs=nothing
%>
<%
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")
'Open the file for writing
Set f = fso.CreateTextFile(s_path & "/" & s_file_being_created, True)
f.Write(m)
f.Close
Set f = Nothing
Set fso = Nothing
%>
For those of you writing ASP with JScript instead of VBS, the code might look something like this:
var fileSystemObject = Server.CreateObject("Scripting.FileSystemObject");
var textStream = fileSystemObject.CreateTextFile(filePath, true, true);
textStream.Write(fileContent);
textStream.Close();
delete textStream;
delete fileSystemObject;
Documentation references:
Scripting.FileSystemObject object
FileSystemObject.CreateTextFile() method
TextStream object
Write() method
Close() method
delete operator

Please help me.
You need to modify your code like this
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
bindDDL();
}
protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
string s = ddl.Text;
}
public void bindDDL()
{
DataTable dt = new DataTable("Drop");
dt.Columns.Add("ID", typeof(int));
dt.Columns.Add("Name", typeof(string));
dt.Rows.Add(1, "ABCD");
dt.Rows.Add(2, "EFGH");
ddl.DataSource = dt;
ddl.DataValueField = "ID";
ddl.DataTextField = "Name";
ddl.DataBind();
}

you can pass your data for dropdownlist by ViewBag:
ViewBag.ProfileId = new SelectList(db.UserProfiles, "Id", "Username");
and get in your view :
#Html.DropDownList("ProfileId", String.Empty)
or another example :
Controller
public ActionResult Index()
{
List<SelectListItem> obj1 = new List<SelectListItem>();
obj1.Add(new SelectListItem { Text = "Text1", Value = "1" });
obj1.Add(new SelectListItem { Text = "Text2", Value = "2" });
obj1.Add(new SelectListItem { Text = "Text3", Value = "3" });
List<SelectListItem> obj2 = new List<SelectListItem>();
obj2.Add(new SelectListItem { Text = "Text1", Value = "1" });
obj2.Add(new SelectListItem { Text = "Text2", Value = "2" });
obj2.Add(new SelectListItem { Text = "Text3", Value = "3" });
ViewBag.State1 = obj1;
ViewBag.State2 = obj2;
return View();
}
View
#Html.DropDownList(“State1”)
#Html.DropDownList(“State2”)
but in my opinion better way is using ViewModel for this issue .

aTextBox.Text = TextBox1.Text;
Button ButtonDelete = new Button();
ButtonDelete.ID = "ButtonDelete" + arrayButton.Count.ToString();
ButtonDelete.Text = "Delete";
//if (TextBox2.Text != "")
//{
// String red = TextBox2.Text.ToString().Substring(0, 2);
// String green = TextBox2.Text.ToString().Substring(2, 2);
// String blue = TextBox2.Text.ToString().Substring(4, 2);
// int r = int.Parse(red, NumberStyles.AllowHexSpecifier);
// int g = int.Parse(green, NumberStyles.AllowHexSpecifier);
// int b = int.Parse(blue, NumberStyles.AllowHexSpecifier);
// aTextBox.BackColor = System.Drawing.Color.FromArgb(r, g, b);
//}
arrayTextBox.Add(aTextBox);
arrayButton.Add(ButtonDelete);
for(int i=0;i<arrayTextBox.Count;i++)
{
PlaceHolder1.Controls.Add(arrayTextBox[i]);
PlaceHolder1.Controls.Add(arrayButton[i]);
PlaceHolder1.Controls.Add(new LiteralControl(#"<br />"));
}
//ButtonDelete.Click += new EventHandler(ButtonDelete_Click);
Session["arrayTextBox"] = arrayTextBox;
Session["arrayButton"] = arrayButton;
TextBox1.Text = "";
//TextBox2.Text = "";
}
}
}
foreach the arrayTextBox and get TextBox, then use PlaceHolder1.Controls.Remove(Textbox)
You can use the code below.
Note: I used CommandArgument of the button to store the id of corresponding textbox and then use Page.Controls.Remove in the btn click event:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
CreateTextBox();
}
else
{
Session["arrayTextBox"] = null;
Session["arrayButton"] = null;
}
}
protected void ButtonDelete_Click(object Sender, EventArgs e)
{
Button btn = Sender as Button;
if(btn != null)
{
String szTextControlID = btn.CommandArgument;
Control ctl = Page.FindControl(szTextControlID);
Page.Controls.Remove(ctl);
Page.Controls.Remove(btn);
}
}
protected void CreateTextBox()
{
List<TextBox> arrayTextBox = new List<TextBox>();
List<Button> arrayButton = new List<Button>();
if (TextBox1.Text != "")
{
if (Session["arrayTextBox"] != null)
{
arrayTextBox = (List<TextBox>)Session["arrayTextBox"];
arrayButton = (List<Button>)Session["arrayButton"];
}
TextBox aTextBox = new TextBox();
aTextBox.ID = "aTextBox" + arrayTextBox.Count.ToString();
aTextBox.Text = TextBox1.Text;
Button ButtonDelete = new Button();
ButtonDelete.ID = "ButtonDelete" + arrayButton.Count.ToString();
ButtonDelete.CommandArgument = aTextBox.ID;
ButtonDelete.Text = "Delete";
ButtonDelete.Click += new EventHandler(ButtonDelete_Click);
//if (TextBox2.Text != "")
//{
// String red = TextBox2.Text.ToString().Substring(0, 2);
// String green = TextBox2.Text.ToString().Substring(2, 2);
// String blue = TextBox2.Text.ToString().Substring(4, 2);
// int r = int.Parse(red, NumberStyles.AllowHexSpecifier);
// int g = int.Parse(green, NumberStyles.AllowHexSpecifier);
// int b = int.Parse(blue, NumberStyles.AllowHexSpecifier);
// aTextBox.BackColor = System.Drawing.Color.FromArgb(r, g, b);
//}
arrayTextBox.Add(aTextBox);
arrayButton.Add(ButtonDelete);
for(int i=0;i<arrayTextBox.Count;i++)
{
PlaceHolder1.Controls.Add(arrayTextBox[i]);
PlaceHolder1.Controls.Add(arrayButton[i]);
PlaceHolder1.Controls.Add(new LiteralControl(#"<br />"));
}
Session["arrayTextBox"] = arrayTextBox;
Session["arrayButton"] = arrayButton;
TextBox1.Text = "";
//TextBox2.Text = "";
}
