You can save a DataTable in viewstate. Add a new row to your Datatable and then rebind the grid.
I didn't get any requirements for the signature

Hello Genious..
I have some word files on server.. that i need to download all of them together..
So i have only one option that first i create a zip file from all these files and then then download this zip file..
So my functionality achived.
But when i extract these zip file and opens word any of word files within downloaded zip file, Opened Word file shows only byte data means some thing like lots of Sqaures which may be same as bytes of files..
and obeviously word file should display actual content in readable character..
Any Suggestons will appreciated...
If needed the please refer to my code..
For i As Integer = 0 To strFileToDownload.Count - 1
Dim strFileName As String = Path.GetFileName(strFileToDownload(i))
Dim MyFileStream As FileStream = File.OpenRead(strFileToDownload(i))
Dim buff() As Byte = New Byte((MyFileStream.Length)) {}
'Dim zipEntry As New ZipEntry(strFileToDownload(i))
Dim zipEntry As New ZipEntry(strFileName)
zipOS.PutNextEntry(zipEntry)
zipOS.Write(buff, 0, buff.Length)
zipOS.InitializeLifetimeService()
MyFileStream.Close()
Next
' Compress and close the zip file
zipOS.Finish()
zipOS.Close()
Response.ClearContent()
Response.ClearHeaders()
Response.ContentType = "application/zip"
Response.AddHeader("Content-Disposition", "attachment; filename=" + "CMM " + strProjectSize + " size Project Documents" + System.IO.Path.GetFileName(strNow))
Response.WriteFile(strNow)
Response.Flush()

I can sort a column on the first page,but when i go to second page through paging sorting changed it's order.
Another problem is When i click Edit button,sorting is changed as a result data are also changed for which i can't edit the actual row rather i see a different data on the same row to be updated.
Here is my code...
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
OnPageIndexChanging="pagemethod" OnSorting="sortmethod" OnRowEditing="editmethod"
AutoGenerateColumns="False" PageSize="4" >
<Columns>
<asp:CommandField HeaderText="Edit" ShowEditButton="True" ButtonType="Button" />
<asp:TemplateField HeaderText="Name" SortExpression="Name">
<ItemTemplate><%#Eval("Name")%></ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtname" runat="server" Text='<%# Eval("Name") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridView();
}
}
public void BindGridView()
{

ds=binddata();
GridView1.DataSource = ds;
GridView1.DataBind();
}
public DataSet binddata()
{
SqlConnection con = new SqlConnection("Server=.;database=emp;uid=sa;pwd=;");
SqlDataAdapter da = new SqlDataAdapter("select * from job", con);
con.Open();
DataSet ds = new DataSet();
da.Fill(ds, "emp");
return ds;
}
public void sortmethod(object sender, GridViewSortEventArgs e)
{
ViewState["sortcolumn"] = e.SortExpression;
if (ViewState["sortorder"] == null)
{
ViewState["sortorder"] = "asc";
}
ViewState["sortorder"]=ViewState["sortorder"].ToString() == "asc"?"desc":"asc";
DataView dv = new DataView(binddata().Tables[0]);
dv.Sort = ViewState["sortcolumn"] + " " + ViewState["sortorder"];
GridView1.DataSource = dv;
GridView1.DataBind();
}
public void pagemethod(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.EditIndex = -1;
BindGridView();
}

Hi,
I am developing website that contains the flash file on home page.
And that flash file reads the images based on xml file.
In admin panel, administrator can select images that can be showed in flash file.
After changing xml file(server side), that is not reflected to the front end because xml file is cached.
To see the changed images, i must close the window and start new session.
Plz help me
Thanks in advance.

Hi,
I have a simple application which generates Excel reports. I use Response.BinaryWrite() to write whatever excel content i have to the client (client is prompted to save). I need to change some status message on my webpage after the excel generation process. However, this cannot be done since Response.Binary just flushes the excel file to the client and that's it.. Can someone plz suggest a way i could get the status changed prior the excel generation process plz?
Thank you
Carpe diem,
