Asp.net - Group Values In A Nested Repeater?

Nov 29, 2011

I have a table of questions and a table of alternatives corresponding to each question. I'm planning to build a questionnaire system (in ASP.NET) which select a few random questions from that total of questions.

I'm using the following SQL Statement to choose the random questions:

SELECT TOP (@maxQuestions) QuestionID, QuestionName FROM Questions WHERE CourseID = @CourseID ORDER BY NEWID()

Which populates a DataTable in a DataSet and data bind it to a Repeater control (the parent Repeater). What I need now is to get every alternative related only to the current random questions generated from the query above in a separate SQL Statement so that I can populate the DataSet with a new DataTable, add the relation between them two and data bind it to another Repeater control (the child repeater).

I don't know how to get only the alternatives related to the current random questions I generated.Otherwise, I get an error saying that I don't have all child values corresponding to the parent values and I can't group the alternatives inside the same question.

Asp.net - Nested Repeater Show Data That Matches Parent Repeater

Mar 15, 2011

I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.

Something similar to that.

row1 tour1
row2 tour 1
tour1 subtotal

[Code].....

but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater

Get Value Of Label When Button Clicked In Nested Repeater Asp.net Vb?

Oct 14, 2011

I have nested repeaters, each item in the nested repeater has a label and a button on it, i want to beable to access the label.text when the button is clicked, I think i'm nearly there as I can return the index of the repeater and nested repeater that is clicked, i'm just having some trouble finding the label itself.

You might be able to help me without me posting the repeater code. Here is my code behind for when the button is clicked.

Protected Sub btnEditUser_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim btnEditUser As Button = DirectCast(sender, Button)

[Code]....

I'm currently getting this error 'Object reference not set to an instance of an object.' when trying to write the value of UserId.Text so i think i've got it slightly wrong in this line:

Dim UserId As Label = DirectCast(reClients.Items(selectedClient).FindControl("lUserName"), Label)

Sql - Group By Having And Count As LINQ Query With Multiply Nested Tables?

Feb 28, 2012

I have the following SQL query to return all Customers who have no OrderLines with no Parts assigned - i.e. I only want the customers within which every order line of every order has no parts assigned - (in the actual problem I am dealing with a different domain but have translated to customers/orders to illustrate the problem)

SELECT c.Customer_PK
FROM Customers c
INNER JOIN Orders o[code].....

This works but generates less than optimal SQL - it is doing a subquery for Count on each row of the customers query rather than using Group By and Having. I tried making the LINQ Group By syntax work but it kept putting the filter as a WHERE not a HAVING clause.Edit in response to Answers below: I am accepting JamieSee's answer as it addresses the stated problem, even though it does not produce the GROUP BY HAVING query I originally had.I am a VB developer so I have had a crack translating your code to VB, this is the closest I got to but it does not quite produce the desired output:

Dim qry = From c In context.Customers
Group Join o In context.Orders On c.Customer_PK Equals o.Customer_FK
Into joinedOrders = Group[cod].....

The problem I had is that I have to push "jl" into the Group By "Key" so I can reference it from the Where clause, otherwise the compiler cannot see that variable or any of the other variables appearing before the Group By clause.With the filter as specified I get all customers where at least one order has lines with no parts rather than only customers with no parts in any order.

LINQ Query To Group Data Between Two List Collections, Populating A Nested Object

Oct 26, 2011

I have these objects:[code]Using LINQ I need to take a List(Of MakeInfo) and a List(Of ModelInfo) and aggregate the StockInfo from ModelInfo into the List(Of MakeInfo).So for each MakeInfo I will have a total count of all stock where MakeInfo.Name = ModelInfo.Make, and also a minimum price.I think it's going to be something like this, but I'm having trouble accessing the nested object and not sure if it's going to be possible with a single query.[code]

Get Values From HTML Radio Buttons Inside A Repeater?

Dec 2, 2011

I have a simple questionnaire system which shows a random number of questions to the user out of a certain total in my database.I have 2 separate tables: Questions and Alternatives (which are the options to answer) related by QuestionID field in both tables. I rendered such questionnaire using Nested Repeaters (parentRepeater for questions and childRepeater for the options) and it shows correctly on the page.Each option is a radio button which I had to use it as a HTML instead of the Standard Server Control <asp:RadioButton> because of the Dynamic ID problem inside a repeater.[code]What I don't know is how do I get all the questions answered by the user given that I don't know the QuestionIDs and the Alternative IDs since it's randomly generated and using a HTML input tags?

VS 2008 : Getting Values Of All Text Boxes Within A Group?

Aug 25, 2011

Im attempting to loop through all the text boxes inside of a group box, and add the text into a list box to later be written to a text file. Here is the code I am using.

Dim cControl As Control
Dim FILE_NAME As String = "Tester.efw"
Dim Group As GroupBox

[code]....

Now instead of locating only the text boxes, apparently it is still trying to identify the labels as text boxes, because I am getting this error:Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.GroupBox'.

VS 2008 Writing Control Values From XML To Controls Within Group Boxes?

Nov 28, 2010

So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.
