I have hard time trying to find the solution to retrieve data from multiple tables in one database.
table Kategorije has fields: idKategorija, naziv, opis table Clanak has fields: idClanak, idKategorija, naslov, autor,...
Kategorije.idKategorijais joined with Clanak.idKategorija, but that isn't the solution because I want my web site to show the Kategorije.naziv instead of Kategorije.idKategorija. This is the code I'm currently using to get idKategorije shown on my web site:

I'm currently working on a FOREX Live Trading project that I'm implementing.
I already have a database that stores the CURRENCY PAIR, BUY/SELL, PRICE AND QTY.
But I have a huge problem.
Scenario that is:
A person BUYS EUR/USD at a PRICE of 1.29900 @ quantity 100,000. (This will be recorded in the database table)
Then he BUYS EUR/USD at a PRICE of 1.29950 @ quantity 100,000. (This will then be recorded in the database also)
Then he decides to SELL his EUR/USD at a PRICE of 1.31000 @ quantity 200,000 all out. (How can I check from the database if he previously had make a transaction of BUY/SELL, so that I can do my necessary calculations for the P/L Statement)
I want to create an application where I need to enter date to the ms access database.
I am a bit confused regarding how to make the user to enter date. The options avaliable are:
a. Shall I use a textBox?
b. Shall I go for 3 drop down lists?
or something else.
Some more questions:
1. what date format shall i use? (dd-mm-yyyy, dd-mmm-yyyy, etc, etc or anything else)
2. What datatype shall i use to store the date in the database?
3. What SQL query shall i use to retrieve the data between 2 dates?
let me know if there are multiple options available regarding this application.
I want to make this application as easy as possible for the user.
Having trouble with a web page and connecting to SQL DB. Basically I have a form view table connected up to a SQLDataSourceControl and what I want displayed in the form is only data that has been assigned to the user that is logged on now. I have a "ViewAll" page, which lists EVERY field, regardless of who it is assigned to, but the "MyTasks" page should only retrieve the data of the current user.
I have two tables in my DB, the "Users" table, with user data (including an ID number) - this is used again in the "Tasks" table as a foreign key called "AssignTo". Therefore if user Joe Bloggs with ID number 5 logs on, whenever someone assigns a task to him, they will select number 5 in the "Task" table, as this relates to his User ID.
Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I m new in asp.net. I want to use gridview with a custom business object.
Should i have property in my custom object.is there a way to access object fields.
Is there anything special you have to do to retrieve Filestream data using a SqlDataSource? I'm using VB and have this as my sqldatasource:
<asp:SqlDataSource ID="SqlDataSourceReadPD" runat="server" etc...
SelectCommand="SELECT [PDIPAttachment] FROM [PositionDescriptions] WHERE ([CP_IDString] = @CP_IDString)">
<SelectParameters>
<asp:Parameter Name="CP_IDString" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
PDIPAttachment is a FILESTREAM column in my table called PositionDescriptions
and this is some of my VB cod:
Dim dv As DataView = DirectCast(SqlDataSourceReadPD.Select(DataSourceSelectArguments.Empty), DataView)
Dim dr As DataRowView
For Each dr In dv
Dim data as Byte() = System.Text.Encoding.ASCII.GetBytes(dr("PDIPAttachment").ToString())
Next
The Filestream data has a PDF file in it, but what I"m getting back in "data" are 13 bytes consisting of: "System.Byte[]".
i am currently facing some problem retrieving image for display on a gridview control. the Image data type in the data table is "image". the data that is stored inside the database is in this format "<Binary data>". may i ask if it is possible tojust retrieve a image data of this format and display in the gridview? or do i need to store the image in a image folder for retrieval?

Here is what I want to do: -From a webpage on my website, I would like to upload multiple photos to an sql database, but instead of having a container or field name for each photo, i would like to have multiple photos on one field, on each record.Then, I would like to display it back one record at a time, but with the capability of displaying all the pics from the one field holding the pics. Similar to the function in MS Access, where I can upload mutiple photos in one field and then display them back by just scrolling through them on the same record.

Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
For example:
label1.text = sqlcolumn1.row1.value;
label2.text = sqlcolum1.row2.value;
Etc...
I'm trying to implement a recipe search page that allows users to specify search criteria by selecting checkboxes that match desired recipe attributes. All the data is stored in a database uing tables with 1 - many relationships. Each recipe can have multiple attributes from any of 5 attribute tables. I want to find all the recipes that match the user-selected criteria and display them in a grid. For example, the user may want a breakfast (attribute 1) recipe that is made with fruit and milk (attributes 2 and 3), is low-fat and high fiber (attributes 4 and 5), and takes less than 15 minutes to prepare (attribute 6). The query for this example might look something like:
SELECT distinct recipes.name, recipes.difficulty, recipes.preptime, recipes.cooktime
FROM recipes, recipeMeals, recipeDishes, recipeFoodGrps, recipeNutrients, recipeFixTimes
WHERE recipes.id = recipeMeals.recipeId and recipes.id = recipeDishes.recipeId and recipes.id = recipeFoodGrps.recipeId and recipes.id = recipeNutrients.recipeId and recipes.id = recipeFixTimes.recipeId and recipeMeals.mealId in (1) and
recipeDishes.dishId in (5) and recipeFoodGrps.fdGrpId in (1, 6) and recipeNutrients.nutrAttsId in (2, 3) and recipeFixTimes.fixTimeId in (1)
I' can generate the SQL but can't figure out how to bind it to a grid control. No could I see how to get any of the data controls to build the query for me. Is there a way to say "execute this query and display the results in a GridView"?

By default when the page is loaded the datasource and Gridview bind and display. However since the datasource is heavy I want on page load these 2 will not bind.
