I enter a id in the textbox and based on that it give me a list of all entries in gridview that use that id.
This works.
But if I leave it blank it gives me nothing. I want to make it so if I leave it blank it give me all the id's.
Do I have to modify the sqldatasource on pageload?
I am working with a Detailsview. I am displaying information from a number of different tables, and so when I configure the datasource I have to specify a custom sql statement. I can get it to display the right columns, but I cannot seem to be able to use a where statement.
I am wanting to display the info in the Detailsview based on what is entered into a textbox, but I get an error when I try to add in the where statement. Can someone tell me what I am missing here?
Thanks

Hi!
I have a page (a search page) with sqldatasource, gridview and set of textboxes. The sqldatasource is using stored procedure with parameters. Using the visual wizard i'm associating the parameters with apropriate textboxes controls. It all works, like a charm.
The problem arises when I input some dangerous code in any textbox , like ' or % .
I'm having exception about unenclosed strings, generally info about the possibility of sql injection.
I thought that using ControlParameters, any Parameter in fact is sqlinjection safe, but apparently it isn't.
Does anyone know the right way of achieving my goal? It's very urgent.
Hi,
View 1 Replies View RelatedI have a SQL database with 1 column in it.. it is a do not call registry for my office. I want to make a web application so our leads can go on the web and request to be put on the do not call list. problem is, if their number already exists, it gets a violation of primary key... Normal handling for this would be to do a select query based on user input, and if it exists in the database, tell them that, else do the insert query... Problem is, i cant seem to figure out how to bind the result of the select query to a textbox or label so i can compare the results to do that logic. Any ideas? This is in asp .net 2.0. Thanks! -Dan

I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date.

Hi, it is few days I posted here my question, but received no answer. Maybe the problem is just my problem, maybe I put my question some strange way. OK, I try to put it again, more simply. I have few textboxes, their values I need to transport to database. I set SqlDataSource, parameters... and used SqlDataSource.Insert() method. I got NULL values in the database's record. So I tried find problem by using Microsoft's sample code from address http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.sqldatasource.insert.aspx. After some changes I tried that code and everything went well, data were put into database. Next step was to separate code beside and structure of page to two separate files followed by new test. Good again, data were delivered to database. Next step: to use MasterPage, very simple, just with one ContentPlaceHolder. After this step the program stoped to deliver data to database and delivers only NULLs to new record. It is exactly the same problem which I have found in my application. The functionless code is here:http://forums.asp.net/thread/1437716.aspx I cannot find any answer this problem on forums worldwide. I cannot believe it is only my problem. I compared html code of two generated pages - with maserPage and without. There are differentions in code in ids' of input fields generated by NET.Framework:Without masterpage:<input name="NazevBox" type="text" id="NazevBox" /><span id="RequiredFieldValidator1" style='color:Red;visibility:hidden;'>Please enter a company name.</span><p><input name="CodeBox" type="text" id="CodeBox" /><span id="RequiredFieldValidator2" style='color:Red;visibility:hidden;'>Please enter a phone number.</span><p><input type="submit" name="Button1" value="Insert New Shipper" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "", true, "", "", false, false))" id="Button1" /> With masterpage:<input name="ctl00$Obsah$NazevBox" type="text" id="ctl00_Obsah_NazevBox" /><span id="ctl00_Obsah_RequiredFieldValidator1" style='color:Red;visibility:hidden;'>Please enter a company name.</span><p><input name="ctl00$Obsah$CodeBox" type="text" id="ctl00_Obsah_CodeBox" /><span id="ctl00_Obsah_RequiredFieldValidator2" style='color:Red;visibility:hidden;'>Please enter a phone number.</span><p><input type="submit" name="ctl00$Obsah$Button1" value="Insert New Shipper" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$Obsah$Button1", "", true, "", "", false, false))" id="ctl00_Obsah_Button1" />In second case ids' of input fields have different names, but I hope it is inner business of NET.Framework.There must be something I haven't noticed, maybe NET's bug, maybe my own. Thanks for any suggestion.

I want to add up the values in a couple of text boxes in another textbox. How do I refer to the textboxes?
fields!textbox1.value doesn't work..what does?
I'm just wonder if this is a bug in MS Search or am I doing something wrong.
I have a query below
declare @search_clause varchar(255)
set @Search_Clause = ' "hepatitis b" and "hepatocellular carcinoma"'
select * from results
where contains(finding,@search_clause)
I don't get the correct result at all.
If I change my search_clause to "hepatitis" and "hepatocellular carcinoma -- without the "b"
then i get the correct result.
It seems MS Search doesn't like the phrase contain one letter or some sort or is it a know bug?
Anyone know?
Thanks
Hi!
I dont know if i will explain this correctly, but my problem is with reporting service.
I'm supposed to Sum value in one textbox and than that sum use it in sum in other textbox.
Something like this:
Sum(Fields!Abc.Value/(Fields!dfg.Value+Sum(Fields!abc.Value)),"matrix1_RowGroup1")*100
I get error msg 'The Value expression for the textbox 'textbox49' contains an aggregate function (or RunningValue or RowNumber functions) in the argument to another aggregate function (or RunningValue). Aggregate functions cannot be nested inside other aggregate functions.'
Something like this wont work either Sum(Fields!abc.Value/ReportItems("textbox56").Value)*100
Error The Value expression for the textbox 'textbox55' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers.
So, pls help if you know how to reference textbox in other in body of report.
Thx.

Hi - I'm short of SQL experience and hacking my way through creating a simple search feature for a personal project. I would be very grateful if anyone could help me out with writing a stored procedure. Problem: I have two tables with three columns indexed for full-text search. So far I have been able to successfully execute the following query returning matching row ids: dbo.Search_Articles @searchText varchar(150) AS SELECT ArticleID FROM articles WHERE CONTAINS(Description, @searchText) OR CONTAINS(Title, @searchText) UNION SELECT ArticleID FROM article_pages WHERE CONTAINS(Text, @searchText); RETURN This returns the ArticleID for any articles or article_pages records where there is a text match. I ultimately need the stored procedure to return all columns from the articles table for matches and not just the StoryID. Seems like maybe I should try using some kind of JOIN on the result of the UNION above and the articles table? But I have so far been unable to figure out how to do this as I can't seem to declare a name for the result table of the UNION above. Perhaps there is another more eloquent solution? Thanks! Peter
View 3 Replies View RelatedOur clients want to be able to do full text search with a single letter. (Is the name Newton, Nathan, Nick?, Is the ID N1, N2...). Doing a single character full text search on a table work 25 out of 26 times. The letter that doesn't work is 'n'. the WHERE clause CONTAINS(full_text_field, ' "n*" ') returns all rows, even rows that have no 'n' in them anywhere. Adding a second letter after the "n" works as expected.
Here is an example
create table TestFullTextSearch (
Id int not null,
AllText nvarchar(400)
)
create unique index test_tfts on TestFullTextSearch(Id);
create fulltext catalog ftcat_tfts;
[Code] ....
I have a scenario of where the standard Full-Text search identifies keywords but Semantic Search does not recognize them as keywords. I'm hoping to understand why Semantic Search might not recognize them. The context this is being used in medical terminology and the specific key words I noticed missing right off the bat were medications.
For instance, if I put the following string into a FT indexed table
'J9355 - Trastuzumab (Herceptin)'
AND
'J9355 - Trastuzumab emtansine'
The Semantic Search recognized 'Herceptin' and 'Emtansine' but not 'Trastuzumab'
Nor in
'J8999 - Everolimus (Afinitor)'
It did not recognize 'Afinitor' as a keyword.
In all cases the Base of Full-Text did find those keywords and were identifiable using the dmvsys.dm_fts_index_keywords_by_document.It does show the index as having completed.
why certain words might not be picked up while others would be? Could it be a language/dictionary issue? I am using English and accent insensitive settings?
would you use sql server "full text search" feature as your site index? from some reason i can't make index server my site search catalog, and i wonder if the full text is the solution. i think that i wll have to you create new table called some thing like "site text" and i will need to write every text twice- one the the table (let's say "articles table") and one to the text. other wise- there is problems finding the right urlof the text, searching different tables with different columns name and so on...
so i thought create site search table, with the columns:
id, text, url
and to write every thing to this table.
but some how ot look the wrong way, that every forum post, every article, album picture or joke will insert twice to the sqr server...
what do you think?

I have a table that contains words that will be used to search another table where FullText index has been created on searchable columns. I'm basically trying to run something like this:
SELECT t1.col1, t2.col3
FROM tbl1 t1, tbl2 t2
WHERE CONTAINS (t1.col1, t2.col1)
I know this won't work but is there a way to join these two tables so the words (t2.col1) can be passed as search conditions? There is no common key on both tables so normal join won't work. I'm trying to find a way to pass the search words from one table to another.
I have Sql server 2005 SP2.
I enabled it for Full Text search. Substring search where i enter *word* doesn't return any row.

select * from testtable where contains(description,'"*xting*"') ;
But it works if i do
select * from testtable where contains(description,'"Exting*"') ;
