hi friends
i have gridview in which i add new row button using add row button click
and i also fill that grid and then save the data into database
i m using update panel and script manager for ajax implemantation.i m also maintaining the session.
the addnew row is working but when i click on save the gridview rowcount become Zero..
and the data filled up is lost..
so what is the solution for that
plz tell me.
Thanks

|
|
When is the gridview populated, it could be because the click event affects the gridview and resets it therefore no rows are there
|
|
|
|
|
firsttime gridview is populated at page load then
when i add new rows that is working fine and i call my save data function at save button click
it is ok or not
thanks

How can I use sqltransaction when I am using account transafer in my web appliocation.
Here the requirement is ,I have to insert into 5 tables having same fields with limited columns.I know usage of transaction for inserting into a single table.
My example code is
conn = ConfigurationSettings.AppSettings("connstring".ToString)
sqlconn = New SqlClient.SqlConnection(conn)
sqlconn.Open()
' DG1.Visible = True
'Dim ds As New DataSet
Dim tr As SqlTransaction
Dim cmd As New SqlCommand
tr = sqlconn.BeginTransaction
cmd.Connection = sqlconn
cmd.Transaction = tr
Try
cmd.CommandText = "Update tbl_demand Set no_item = 4 where distcd=30"
cmd.ExecuteNonQuery()
tr.Commit()
Console.WriteLine("table updated successfully.")
Catch ex As Exception
tr.Rollback()
Console.WriteLine("Error: {1}", ex.Message)
Console.WriteLine("Error reported by {1}.", ex.Source)
Console.WriteLine("Money was not transfered.")
Finally
sqlconn.Close()
End Try
If I want to insert/update in different tables how can I commit/rollback on a single buttonclick_event.
Can anybody give me some idea?

Dim tr As SqlTransaction
tr = sqlconn.BeginTransaction
Try
cmd = new SqlCommand("UPDATE table1 ...")
cmd.Transaction = tr
cmd.ExecuteNonQuery()
cmd = new SqlCommand("Update table2 ...")
cmd.Transaction = tr
cmd.ExecuteNonQuery()
'if you need more than 2 then continue to repeat for
'each command you must execute w/in transaction
tr.Commit()
Begin Catch
tr.Rollback()
'handle exception here
Finally
sqlconn.Close()
End Try

Hi guys i installed my vs2005 in c drive
and i have my project in d drive
in that project i am doing fileupload concept
i given server mappath to save file:
fileupload1.PostedFile.SaveAs(Server.MapPath("\") & "OnLineResumes\" & filename)
now my quest is
the uploaded file will go and store in c drive or d drive inside the project...,
Means, in which drive it will consider as server mappath?
And see this is my code and its not at all storing the upload file in any of the drive...
I am getting error message as Failed to map the path '/'
See this is my code in button click event:
Dim sqlquery As String = "-"
Dim docid As Integer
sqlquery = "select isnull(max(ResumeId),1000)+1 from tblonlineresume"
sqlcmd = New SqlCommand(sqlquery, sqlconn)
sqlcmd.Connection.Open()
If sqlcmd.ExecuteScalar() > 0 Then
docid = sqlcmd.ExecuteScalar
End If
sqlcmd.Connection.Close()
sqlcmd.Dispose()
Dim filename As String = docid & System.IO.Path.GetFileName(fileupload1.PostedFile.FileName)
strdate = txtdob.Text
If Mid(strdate, 2, 1) = "/" Then strdate = "0" & strdate
If Mid(strdate, 5, 1) = "/" Then strdate = Left(strdate, 3) & "0" & Mid(strdate, 4, 6)
txtdob.Text = Mid(strdate, 4, 3) & Mid(strdate, 1, 2) & Mid(strdate, 6, 5)
Try
sqlcmd = New SqlCommand("submitOnlineResume'" & ddlJob.SelectedValue & "','" & txtName.Text & _
"',' " & txtemail.Text & "','" & txtQualify.Text & "','" & ddlYpass.SelectedValue & "','" & _
Mid(txtdob.Text, 4, 3) & Mid(txtdob.Text, 1, 3) & Mid(txtdob.Text, 7, 4) & "','" & _
ddlfarea.SelectedValue & "','" & ddlAspec.SelectedValue & "','" & txtsset.Text & _
"','" & filename & "'", sqlconn)
sqlcmd.Connection.Open()
sqlcmd.ExecuteScalar()
fileupload1.PostedFile.SaveAs(Server.MapPath("\") & "OnLineResumes\" & filename)
lblMessage.Text = "The file has been uploaded."
sqlcmd.Connection.Close()
sqlcmd.Dispose()
Catch ex As Exception
lblMessage.Text = ex.Message
Finally
End Try
sqlcmd.Connection.Close()
sqlcmd.Dispose()

We are implemenmting the MicroSoft Indexing search in our site.our client asked to give provision to search the main folders only, not for SubFolders. So we decided to use the SHALLOW TRAVERSAL OF. But still now we didnt get the correct syntax.
My code:
System.Data.OleDb.OleDbConnection odbSearch = new System.Data.OleDb.OleDbConnection("Provider=\"MSIDXS\";Data Source=\"Agaram\";");
System.Data.OleDb.OleDbCommand cmdSearch = new System.Data.OleDb.OleDbCommand();
cmdSearch.Connection = odbSearch;
odbSearch.Open();
cmdSearch.CommandText = "select Vpath, path, FileName, size, write, attrib, Characterization, DocTitle, rank from scope('' SHALLOW TRAVERSAL OF ("/Software")'') where FREETEXT(contents,'" + searchText + "') order by rank desc ";
System.Data.OleDb.OleDbDataAdapter SqlDa = new System.Data.OleDb.OleDbDataAdapter(cmdSearch);
DataSet Ds = new DataSet();
SqlDa.Fill(Ds);
odbSearch.Close();
/Software is the main folder in my project
The Error is at the Select Query.
Error Details:
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS1002: ; expected
Source Error:
Line 34: cmdSearch.CommandText = "select Vpath, path, FileName, size, write, attrib, Characterization, DocTitle, rank from scope('' SHALLOW TRAVERSAL OF ("/Software")'') where FREETEXT(contents,'" + searchText + "') order by rank desc ";

If
Moghan wrote: ("/Software")'') where FREETEXT(contents,'" + searchText + "') order by rank desc ";
is a new line of code then you need to put a + in the line before at the end so that it knows its the end of that line of code

Thanks for ur reply. Harini's answer working fine.
|
|

|

Hi
You need to split the string "\Software" as "\"" for each double quotes with escape character:
See below:
cmdSearch.CommandText = "SELECT Vpath, path, FileName, size, write, attrib, Characterization, DocTitle, rank FROM SCOPE('shallow traversal of " + "\"" + "/Software" + "\"" + "') where FREETEXT(contents,'" + searchText + "') order by rank desc ";
Let me know if that works.

Hi Harini,
Its working fine now. Thank u vary much. From morning onwards i tried a lot.
|
|
|
|
|
Ok ... That is good!!
Harini

Hi,
One more thing, replace the variable searchText as parameter to avoid security (SQL Injection).

This is a good coding practice in any langauge.
