I want to be able to store user searches on our website. The searches are defined using an EntityDataSource. How can I store the underlying SQL that is generated by the EntityDataSource?
View 2 RepliesI only want to execute this JavaScript function runEx() if publicVarFromCodeBehind != "abc".
I am setting the publicVarFromCodeBehind = "abc" in the Page_Load event but anyway the runEx() function is executing. I wonder how this works and how to prevent runEx() from executing though I need to catch the logic from C# and pass on the variable to the JavaScript.

I'm using resources like this; " runat="server" />
Resources are maintained in a database and resourcefiles are generated when new translations are added. Sometimes bad references to keys happens. This results in error on the whole page.
How can I prevent the whole page from crashing when a resource does not exist? I just want a tiny error message where the resource lacks, like "Not found: Users.DetailsUserHeadline".
I also want to dynamically retrieve resources from code behind, by defining the key as a string "Users.DetailsUserHeadline" without any erros.
I need to excute one insert query basend on two different if conditins. If one of them conditions is true then excute block of code.
For Example,

I have tried using OR statement between them but it doesn't work.

I'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.
What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:
setInterval(function, interval)
I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?
My SQL query is below:
Use master
Select der.session_id, der.command, der.status, der.percent_complete, *
From sys.dm_exec_requests as der
Where percent_complete > 0

I am having a meltdown over something that seems so simple and yet isn't working. Here's my scenario.
I have an object structure of tEvents, which contains properties of an event like a run of concerts. tEvents in turn contains an entity set of tEventOptions, which include properties like EventDate, Cancelled etc. I would like to query a list of tEvents using properties of the tEventOptions, for example filtering by date.
My pageis using a calendar object to show event dates. So I am trying to find if any tEvents in the List coming back from the database match the date of the day element being rendered in my Calendar control like so (in this snip 'data' is List and results from a db query):
[code]....
Except r, my query result var, is always true no matter what data it receives. I have tried the sub query using other properties of tEventOption and get the same 'true' result each time. I know that the data does not reflect this result so I clearly have a problem with the structure of my query, but for the life of me I cannot find a way to resolve it.
I want to do execute a LINQ query, and I have the name of the table to query stored in a variable:
string tableName = "SomeTable";

I am getting frustrated with this problem, I dont know what i did, but now I cannot execute any stored procedured when I could last time.When I use my asp.net application to run the query, it finds the stored procedure but when I execute it is sql management studio it says it cannot find the stored procedure even though it is there.I tried to execute other procedures and the samething happens. Even when I try a simple query it says it cannot find the tableI could execute the query if i placed Use [databasename] in front, but even with this, I cannot execute stored procedures.

I have an ObjectDataSource (but perhaps this question is the same for all kinds of DataSources which support parameter collections):
<asp:ObjectDataSource ID="MyObjectDataSource" runat="server"
TypeName="MyData"
OldValuesParameterFormatString="original_{0}"
SelectMethod="GetMyData" >
<SelectParameters>
<asp:ControlParameter ControlID="MyTextBox" Name="MyParameter" Type="String" />
</SelectParameters>
</asp:ObjectDataSource>
As you can see there is a ControlParameter bound to a TextBox on the aspx page. So the content of this TextBox is a parameter for my SelectMethod. But there is a special button on the page: When this button is clicked and a postback occurs I don't want that the DataSource extracts the content of the TextBox to control the selection, instead I want to set a specific hard value "x" as the selection parameter.
How can I do that? Can I "disable" in some way the ControlParameter when this specific button is clicked and set my special value instead? Or is there any other way?

I'm using a List Box to get multiple values that will be used in a query.I can loop over the List Box and create the string.i.e. 'blue','red','purple'The string is used in the query: SELECT * FROM TABLE1 WHERE COLOR IN('blue','red','purple'). Is there a way to parametrize multiple values? @COLOR='blue','red','purple'What will be the best practice to prevent SQL injections in this scenario?
View 10 Repliesbasically i have two dropdown boxes to filter data and textbox with stored procedure bound to gridview.i want to be able to query data depending on the selected value passed,either using one or more parameter values.
i would like seperate sqlcommands to chose from depending on which controls i select to pass parameters.
i have included a parameter Select(control id) as this is declared by the wizard for stored procedure.
but i am not sure how it is defined on the page and passed to procedure.
[Code]....
I have two DropDownLists, and each one has a Control Parameter that references the other.
The idea is that if you select a value in either one of them, it restricts the possible values you can select in the other. And the user may select either one of them first.
Each one has an "All" option for selecting all values. (They are both used to restrict rows that populate a GridView).
This is all done using SQLDataSources.
The problem is that it doesn't seem to work at all. Both DropDownLists are empty, and the SQL that populates them never hits the SQL Server. But there is no error displayed.
If I have it going only one way, it does work, so I think the problem is the recursive nature of having them reference each other.
It would seem to be quite a common requirement, so its there any way of getting this to work?
I've been reading up on SQL Injection and want to go back and implement some measures to prevent these kinds of potential attacks.For example, on our company intranet, we have an address book feature and a search function so the user is able to look a company or a person up from the database/The user will enter their query into a TextBox control and click the Submit button, calling the following function:addybookDS1.SelectCommand = "SELECT * FROM [addressbook] WHERE COMPANY LIKE '%" + search1 + "%' OR CONTACT LIKE '%" + search1 + "%' OR LASTNAME LIKE '%" + search1 + "%' OR EMAIL LIKE '%" + search1 + "%'"search1 is the TextBox controlI had previously implemented this measure:search1 = Replace(search1, "'", "''")But I want to know if there is more I can do here and how I can go about doing it.
