VS 2005 ReportViewer Grouping?
Jan 5, 2010
I am making a report using the reportviewer. I have grouped the data and the group works. But when I try to put some data in the group header, I get the following error:The Value expression for the textbox Dep_Name refers to the field Dep_Name. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.
The data I am trying to display is from a different table then the one that I am using to group the data. Does this mean there is a problem with the relationship between the tables?

The code below randomly selects two players from "Preferences.txt" which has the names of all current players. (not necessarily all saved profiles) Now I need to find the best way to match 'Doer' and 'Receiver' with their profiles in "Players.txt" and get their profile attributes.

I'm trying to determine if a user has printed a report from the ReportViewer control, so I can write the date/time and username to a database table as part of an audit trail.When the user opens a report there is a print button, which calls up a standard print dialog box.However I can't find any way to determine whether the print button has been clicked or not. The reportviewer has a Print event, but this is no good as it's called before the print dialogue is displayed.

Where can I find resources on authoring Reports. Say, I have a VB project and I want to add reports to it, do I have to add a ReportViewer for each report or can I use one ReportViewer for all?
What is the difference between a Report created using the Report Server Project of the Business Intelligence Projects and one created using the Visual Basic/Reporting Project tab? Which one is more suited for creating reports?Only performance counts!

I'm having a heck of a time with transforming a simple SQL Query into a LINQ query(using vb btw)
Here is my SQL:
SELECT USRDEFND5
FROM int_gp_employee
GROUP BY USRDEFND5
[Code]...
I've tried a number of different variations of the LINQ. My current statement is:
From b In xmlFile...<row> Group b...<usrdefnd5> By b...<usrdefnd5> INTO group when I foreach through the resulting collection, EVERY line (17000) shows up.

My VB.net application has a lot of application settings, is it possible to group them somehow(other than having a common name)?For example, my application has a lot of winforms each of which needs to save some information about itself. Is it possible to use something like:
Form1.width = My.Settings.Form1.Width
Form2.width = My.Settings.Form2.Width
etc.

I've a large table of Items and I need to organize them by Category, then by Year and then by Month.Item has CategoryID and Dated properties.I got this far:
Dim Items = From Item In DB.Items _
Group By CategoryID = Item.CategoryID _
Into Categories = Group _
Order By CategoryID
But where I put the:
Group By Year = Year(Item.Dated)
and the
Group By Month = Month(Item.Dated)
The final result should be something like this:
For Each Category in Categories
For Each Year in Category.Years

I am using a nice shopping cart I found online. I would like to translate this code to use a repeater or listview and dynamically retrieve my data, but I cannot seem to find a way to group my data correctly.I know the ListView can group by a certain amount of items, but I have not found a way to do it with this scenario.The shopping cart works by having a ul list of items, followed by their details in the div below. This process starts again by getting three more ul items, followed by three more details. How could I do this using a ListView or repeater? I have not found a way to repeat both of these sets of data I need in a group of three.[code]

I am trying to group various controls (of the same type, e.g., labels together, buttons together, etc.) on a form using a tag or a name of some sort so I can identify all those that belong to tag 'A' and those in tag 'B'. In the end I will have on a form a number of labels grouped as tag 'A' and some labels as tag 'B' so I can change their visible properties on/off.

If a user has a few of my applications open and he/she minimises them I would like to group these in the task bar like MS Word for example.
Product Name - Application 1
Product Name - Application 2
Product Name - Application 3
Product Name - Application 4
Because all of my applications begin with the product in the Title bar can this be achived.

I have multiple sub's that i'd like to group together, however all of the groups need to be in the same class. They all work together, but it would help me organize the code and make it less confusing if I could group some of the different subs together for outlining purposes. Is there a way to do this? I tried to find answers online, but I couldn't find what I was looking for.

I have a class called Trigger. within this class, I can perform a variety of functions, the main of which is to monitor a specific condition. In this class I have a bunch of class variables that are used to setup the condition as well as for information purposes after the condition has executed. All the conditions are stored in a database and when I start the program, I create a New Trigger class for each condition and store the variables (name, desc, action to perform once the condition is met, etc.) I was thinking about changing the class to create a Structure called Configuration where I would store all the variables. But then I would have to save the Configuration within the class so it could be used later on if needed correct?
[Code]...
but in looking at this i realized that I am creating a new structure and then creating a new trigger class where I am saving the Configuration structure which essentially seems the same as just using class variables as I was before. I also looked at creating a Configuration Class and a Trigger Class. then from the main class I would create all the Configurations and have a shared Trigger class that monitored all of them instead of having a single Trigger class for each Configuration. Using this method i could create a hash table that kept track of each configuration that was being monitored and stop it if required.
Does either method sound more appropriate over the other. I am just trying to understand when/why to do things a certain way.

I am trying to summarize a datatable based on a primary column and then add certain columns. For example this table
col-1 col-2 col-3
1 AA 2
2 BB
[Code].....
This simply doesn't do anything becuase it thinks the target table doesn't have a primary key.

I'm building an app that list information. It will have list of each object going vertically, with the information about the object going horz across that line. My issue is I need to scroll through these lines, however each line will contain text, images, scroll bar, button, etc. Just common control items. I first started off grouping them in a panel (panel being everything needed in that one line of information). I was thinking I could spawn more identical panels, one for each object listed. I also tried this using a UserControl (not sure if this is the right thing to do). I just need a simple panel or area that I can layout my controls as need, then create identical panels as needed for each line. Then I can just scroll through then using some script to mod there location. Panel? UserControl? I've tried the usercontrol, however I coudlnt get it to show on the form.

I vaguely remember something about a hotkey or menu that would group controls together at design time so you could drag 2 or more controls around and they would remain relative to eachother. You could work on something else and come back and the controls would still be grouped.
Does anybody know what this feature is called and how I can access it?

I have a table in my oracle database, with the following schema: student(studentNumber,name, dateOfCreation).
dateOfCreation is the date in which the student record was created.
In crystal reports, I have to group the records into the following groups, using the dateOfCreation field:
Older than 4 weeks(Records whose dateOfCreation is more than 4 weeks ago). Between 2 and 4 weeks (Records whose dateOfCreation is more than 2 weeks ago, but less than 4 weeks ago). Between 1 and 2 weeks(Records whose dateOfCreation is more than 1 week ago, but less than 2 weeks ago). Less than 1 week (Records whose dateOfCreation is less than 1 week ago).
I have tried grouping in specified order using group expert

I am trying to reduce the amount of code I have and make it more maintainable and flexible. (I.E Do it the right way). I have a bunch of (48) Form controls (text boxes) and when I click next on that form I save all their text values to some 48 global string variables. The names of these variables are the same as the Text Boxes but with "_saved" appended to them.
For any given operation instead of having a separate line for each control it's nice to just use a loop. I can easily write some code to operate on each Control (set visibility, enabled etc) by using Me.Controls and a For Each Loop. I can even make collections of fractional groups of the 48 controls. For example, If cntrl.name.startswith("sometext") collection.add or perform some other operation only on that subgroup etc.
I'd like to do something similar with my Saved Public String Variables. For example I would like to do the following loop somehow but don't know how to group Variables together and keep their name in a way where I can define that array or collection on 1 line or just a couple lines.
' But this next line only groups the values
Group_of_string_Variables = {Var1, Var2, Var3, Var4}
For Each Name_of_String_Variable In Group_of_string_variables
[Code].....
But I can not access the name of a variable or find a way to easily group in key/value 48 different ones without needing much more than 50 lines of code to make either a 2-dim array, a collection, or a hash.
I'm sure someone will tell me I should be doing it a completely different way. That would be ok as long as I don't have to change too much of my other code. I thought of making an object of some kind instead of a variable so I could access 2 object properties- name and value then I could group those objects in a collection as I have done before. But that seems like it would be many more lines of code and I'm not sure it would work.
