You can also try following line for newline in richtextbox.

richTextBox1.Text = "Some text " + Environment.NewLine + "Again some text.";

Viewstate not updated after TransmitFile

KittyKit22-Jul-10 10:53

22-Jul-10 10:53

Hello there

I have been spending almost half-a-day to get this problem solved, but could not even find a single article that would help me. I wonder whether nobody else has faced this problem.

Okay, my webpage involves creating excel files. My download button has code like this

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=clientcopy.xlsx");
HttpContext.Current.Response.TransmitFile(Server.MapPath("App_data/" + Viewstate["FileName"]));
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();
HttpContext.Current.Response.End();

Alright. this works fine. The problem is, After downloading I want to make Viewstate["FileName"] to be null. But whatever I do, during the next post back after the filetransmit, the Viewstate["FileName"] still retains the old value and refuses to get updated to null. I tried writing the Viewstate["FileName"] = null; at every possible place in the above code - at the begining, in the middle and at the end after response.end(). BUT no way Cry | :((

Can someone help on how to modify the viewstate after a file transmit???

Note:
=====
My webpage has an update panel. Button "GO" displays a report in the update panel based on some selections outside the updatepanel. Button "ADD" keeps on adding the displayed reports to an excelfile until Button "download" is clicked and excelfile is downloaded. "GO" and "ADD" triggers partial postback and "download" triggers fullpostback.

thanks
Kit

You may want to read this msdn[^] article about view states.

You may have to override the SaveViewState() method on the page and set the value to null. Don't forget to call the base.SaveViewState() through!

May I help you?

Try this

HttpContext.Current.Response.TransmitFile(Server.MapPath("App_data/" + Viewstate["FileName"]));
Viewstate["FileName"] = "";
HttpContext.Current.Response.Flush();

ViewState is the state of the "View", or in other words the state of the page displayed in the browser. Since the transmission of the file doesn't change that view it wouldn't change the ViewState. If you want something that can be changed with the file transmission you need to use a data location that can be affected by it. I suggest setting a cookie.

Thanks for the replies, guys.

@Yusuf: The link seems to be really good and informative. will go thro it. thanks. As a quick try, I tried overriding the SaveViewstate function. But that didnt help.
@Prosanta: It didnt work either. As I mentioned earlier I had placed the code at every possible location
@Gray: I think i will try storing it in the session. What say?

HTML Print of Selected Tab using RenderControl Method

Hi To All,

Can anybody help me how to print the selected tab in the Ajax tab container in HTML format?

On Button click I have to print the selected tab in HTML format.
So I have written one method for that.

public void RenderControl(Control ctrl)
{   
StringWriter tw = new StringWriter();   
HtmlTextWriter hw = new HtmlTextWriter(tw);   
ctrl.RenderControl(hw);   
String sb = tw.ToString();   
Response.Write(sb);   
Response.End(); 
}

protected void Button2_Click(object sender, EventArgs e)
{   
TabPanel tbPnl = TabContainer1.ActiveTab;   
RenderControl(tbPnl);
}

But I got the bellow mentioned exception when I click on the button in the application.

Script control 'TabPanel2' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

Any Help regarding this will be greatly appreciated..

Thanks in Advance...

From following code you will get particular TabPanel. So you
need to check properties of tab panel to get HTML.
Then you can print easily.

AjaxControlToolkit.TabContainer container = (AjaxControlToolkit.TabContainer)TabContainer1;
foreach (object obj in container.Controls)
{
    if (obj is AjaxControlToolkit.TabPanel)
    {
        AjaxControlToolkit.TabPanel tabPanel = (AjaxControlToolkit.TabPanel)obj;
        //Now check properties of tabPanel to get HTML.
        //there must be some way.
    }
}

You can also change color of particular row or column at
run time based on some condition.
i.e.

if(SomeCondition)
{
    datagridview1.Columns[0].DefaultCellStyle.BackColor = Color.Aqua
    datagridview1.rows[3].DefaultCellStyle.BackColor = Color.Aqua
}
else
{
    datagridview1.Columns[0].DefaultCellStyle.BackColor = Color.Blue
    datagridview1.rows[3].DefaultCellStyle.BackColor = Color.Blue
}

Getting sessions to ASMX webservice

Matt Cavanagh21-Jul-10 8:40

Matt Cavanagh

21-Jul-10 8:40

I have an ASMX webservice hosted alongside my ASP.NET web app. It is in the same project, hosted as the same IIS web application, and compiles to the same DLL. Now, I need to get the users session into the Webservice. To test this I made this simple method:

[WebMethod(EnableSession = true)]
    public string checkSession()
    {
        return HttpContext.Current.Session["userid"].ToString();
    }

So, first I login to my web app, then in the browser goto my webservice and click "checkSession" on that auto generated test page. I have tested this on 3 computers. All 3 of those work fine with the webapp(so the sessions are being created etc), and 2 of those return the value of Session["userid"] on invoking the webmethod, however the last computer returns "Object reference not set to an instance of an object" because Session is null.

So, whats the difference between these computers and why can my ASP.NET app get the sessions on all computers but the webservice cant?
I have also tested with my cellphone and it works there too.

Thanks Smile | :)
