I have an SqlDataSource with following command:
SELECT * FROM [vw_aspnet_MembershipUsers] WHERE ([UserId] = @UserId)
When I pass simple GUID like "3bd08871-d5d6-4f38-8c8a-29fd6077a719" as a UserId, then nothing gets selected. So what is the correct format for passing the GUID value?
[code]....
Is ther a way I can tie DataSource to SqlDataSource on aspx page and pass select parameters?
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
Gridview has many columns and a Delete button as well. Delete button is a control as TemplateField
[code]....
Now associated SQLDataSource's Delete command's stored procedure is expecting two parameters. One is going from DataKeyNames (RowID), other one i wanna pass is the Text of btnDelete (True or False).
i have placed a SqlDataSource component on my aspx page but while configuring the SqlDataSource in the "Test Query" Step I am passing the following parameters :But when i click ok it returns following error:This error occurs when i pass the string :
INFO, WARN, ERROR,
I have tried a lot of combinations but nothing works. It works only if i pass one of the three words in single quotes like this :'ERROR'Infact the INFO WARN and ERROR are the various levels available in the table. Each record can have only one level and in the sql query i am using IN("-----") to match the criteria, hope you understand.
i have two tables named
1.LookupPageInfo and (LookupPageInfoId,pathmessageID,pagemessageID)
2.Messages (MessageId,MessageText,ChannelID)
Now i need to write a query something like this........in the query i need to pass the pathmessageid and needs to get messagetext from Messages Table,i am not sure how i need to write the below query..can someone guide me how can i write a query......as below..
select LookupPageInfoId,
PathMessageID,
pagemessageID,
(select messagetext from Messages where MessageID=PathmessageId) as TEXT from LookupPageInfo

View 1 RepliesI have multiple connectionString's to multiple databases in my web.conf. I do this to query multiple databases from a single query page. This query is past thru a url to another page (asp.net 2 with .vb page behind; no code in page behind presently), which contains the query info or sqldatasource. This page contains numerous sqldatasource due to querying multiple databases.
My problem arise's if one of the databases is down. This prevents me from searching the other databases (error, because no connection string).
My question is: Is there a way to create a checkbox for each connectionString or sqldatasource allowing me to select the database to search. if a database is unavailable; simply unchecking that database would allow me to search the other databases without error message.

I am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:
[Code]....
<truncated>
What I want is to grab the screenshotId from the SqlDataSource when the usp_GetOrderDetails stored proc gets called and populate it into a field on the page called screenshotId. I then want to use this screenshotId to get an image from the database based on Id. populating the screenshotId field. How do I do this - do I need to have something like OnDataBound or something like that?
What ive been using now is getting datas in code-behind, passing datasource into a Session, re-binds it to a gridview whenever there's paging/sorting needed. What i want to know is what is better if its performance we are talking about?
Is it datasource into a session Or SqlDataSource for which I know whenever paging/sorting needed is that sqldatasource opens up a DB connection to get the datas again?
I have an editable grid where user can add/edit data. They also have the option to load previously entered data from last month. When the user then clicks save, i want to readd this newly modified data as a new record for this month. So basically I want to call the insertcommand, but it does not work. My 'save' method just 'updates' the records.

I'm using Visual Web Developer 2010 Express. This is my first attempt at creating a .NET page. I have a Gridview on a page that displays the results of a GridQuery. This works. I have a checkbox control(cb_Filter) on the same page that if checked, should add to the where clause of the GridQuery, (where Column5 IS NULL). How do I check the state of the check box so it will run the query with or without the "filter".

The ControlParameter refers to a valid object on the page.
