Hi,
How to use save File Dialog Box in asp.net+C#.net. Any related Controls?
First thing is that any save file dialog box is there in asp.net.
Regards,

Ya is there and you Google it.  Do you want to upload a file to a server ... Correct. Server control is there.
|
|
|
|
|
Thanx. When I click the button (ie)it should show like the save file dialog and ask for file name to save and store the full path in a string type variable in asp.net with c#. its urgent.

NO This feature is not use in ASP.net
If you want to save any file then make a dynamic link.
And when clicking on this link it will ask to save file.

You're wrong. Passing a file through a binary write, will create a save file dialog.

I have an application developed using Visual Studio 2005 and VB.Net which displays data from an Access database. I can launch it from within a GIS system (Manifold) by doubl-clicking a point on a map drawing. This passes parameters and the name of the .aspx page to lunch so as to display the data on the database associated with the point. The application is run on a PC under localhost
The problem is that unless I have already launched the ASP.Net Development Server the .aspx page will not display - get not able to display type of error message. Is there some way I can ensure that Asp.Net Development Server is always launched - either every time the PC is switched on, or by some code is the home page of the application?
Also:
a)is there a way of always making the ASP.Net Development Server run irectly under the root localhost port at present it usually is Port 1347.
b) If I deploy the application to another PC which does not have Visual Studio loaded, what do need to ensure the PC has installed to run .aspx pages?

I think you are using the built-in wev server which comes with VS 2005. This web server will be launched only when you run the web application from VS 2005. Instead, you can use IIS to host your web application.
Windows XP based PCs have IIS ver 5.x. You can use that to deploy you application so that you don't need to lauch everytime.

Ramesh - thanks for reply. I've investigated further and the problem seems to be with the fact that the Access database is opened. When I open the GIS application, because the GIS links to the Access database, the database is opened. When I try to open the .aspx page with localhost
ie, using Internet Explorer,
http://localhost/HA4Com/chamber.aspx?cname=2977-001
get error message file already in use
Exception details: System.Data.OleDb.OleDbException: Could not use; file already in use
If however I use the VStudio Development Server:
http://localhost:1347/HA4Com/chamber.aspx?cname=2977-001
it works Ok. Looks like VStudio development Server happy that Access database already open, but IIS is not.
Any way I can make localhost/IIS to accept the database already opened?

I can use Session on login.aspx.cs.
so I used like this.
// Session["Id"]= id;
and I can see components of Session, when I type "Session".
but I can't use that another aspx.cs. page, for example, board.aspx.cs.
There are only two values. SessionPageStatePersister and SessionParameter.
That is all;;
I don't know why...
please let me know..
|
|
|
|
|
that class file is not inherited System.Web.UI.Page class ? If it is then you will be getting Session while development.
|
|
|
|
|
Oh, THank you very much.
you are right.
that class file was not inherited System.Web.UI.Page class.
Really thank you.^^

I'm making a login page with ASP.NET with C#.
and I know that it needs to use Session for saving information of loggined user.
so I used Session like this on "login.aspx.cs" with Login View Control.
[login.aspx.cs]
// Database query.
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Join"].ConnectionString);
SqlCommand cmd = new SqlCommand("SELECT * From User WHERE id = @ID", con);
cmd.Parameters.AddWithValue("@ID", ((TextBox)LoginView1.FindControl("TextBox1")).Text);
string name = rd["name"].ToString();
string pw = rd["password"].ToString();
string pw1 = ((TextBox)LoginView1.FindControl("TextBox2")).Text;
string id = rd["id"].ToString();
// Save to Session variables. There are a lot of components about Session. Keys, Item, Add,
//and so on..
Session["memberid"] = id;
Session["membername"] = name;
if ((string.Equals(pw, pw1)) == true)
{
FormsAuthentication.RedirectFromLoginPage(name, false);
}
....
And I made codes like this whether lggined user is same with Writer on board or not.
[Board.aspx]
public static bool IsWriter(string pdsId, string Writer)
{
string sql = "Select id From t_Pds Where boardId = @boardId And writer = @writer";
SqlCommand cmd = new SqlCommand(sql, DbConn.GetConn());
cmd.Parameters.AddWithValue("@boardId", pdsId);
cmd.Parameters.AddWithValue("@writer", Writer);
cmd.Connection.Open();
string result = (string)cmd.ExecuteScalar(); // result = ID of writer value.
cmd.Connection.Close();
// I can't use Session. When I use "Session", there are no components of Session.
// There are only two values of Session. ( SessionPageStatePersister , SessionParameter)
if (Session["memberid"] == result) //ERROR.
{
return true;
}
else
return false;
}
}

How do I get a aspx page function in App_code class file in asp.net 2.0.
please sent a demo code.
|
|
|
|
|
You cannot get a function defined in the aspx code behind file in the App_Code class file. Because the instance of the aspx class is created based on the request by the browser in IIS at run time. You can try a static function but it isn't good practice.
You need to define the functions used across the application in another App_Code class file.

Hi,
In a gridview i have taken the three buttonfields.At one time i am showing the gridview with those three buttonfields.But at some time i dont want to show those three buttonfield i.e., i want to make it invisible.
How can i do it...
Thanks in advance..
|
|
|
|
|
Do you want to make invisible the columns of the three button fields in the GridView or you want to make invisible the button fields in some rows?
|
|
|
|
|
i want to make those three columns invisible.
|
|
|
|
|
Assume that the three button field columns starts from 4th column of the GridView, then
gvYourGridView.Columns[3].Visible = false;
gvYourGridView.Columns[4].Visible = false;
gvYourGridView.Columns[5].Visible = false;

Can you post the portion of the code where you extract the value of the hyperlink.
Try this:
LinkButton lbtnYourHyperLink = (LinkButton)(gvYourGridView.Rows[rowIndex].FindControl("lbtnNameOfLinkButton"));
if(lbtnYourHyperLink != null)
textbox1.Text = lbtnYourHyperLink.Text
