I have a small repeater which loops through up to about 10 items in a database, and does database calls within each repeat to get the values (Numerical) required to enter into a <p> tag in the HTML.
Once the repeater has completed I need to get the sum of all the <p> tag values.[code]...
I have one control named thumbviewer inside repeater. I want to set its imageurl in
code. Currently it's done in aspx itself as
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate>
<span style="padding:2px 10px 2px 10px">
<bri:ThumbViewer Id="Th1" runat="server" ImageUrl='<%# Eval("Name", "images/{0}") %>' Height="100px" Width="100px"/>
</span></ItemTemplate>
</asp:Repeater>
How can I set ImageUrl in code?
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.
I have a repeater which displays products. Users can select a Size - dropdownlist and an Amount - textbox. Then they press Order or Cancel. When they press Cancel I would like the values of Size and Amount to return to their default values.
Protected Sub lbtnCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnCancel.Click
rpt.ProductList is the repeater name
lblFeedback.Text = ("")
lblFeedback.ForeColor = Drawing.Color.Black
End Sub
I am using VB.NET.
I am trying to pass values within a repeater binding them to a button and pass them from this form to another form. When I compile this it gives me an error indicating.

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?

I am using VB.Net with Framework Version 2.0.
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
I have a parent repeater with nested repeaters.My problem is I am trying to use 'Next' and 'Previous' buttons to rebind my repeater (rptTabContent) and thus the inner repeaters also, but when I try to manipulate the state of these links during the ItemCommand event they are overwritten by the bind.

I am using vb.net and WPF. In a wpf window I am showing a datagrid in the load event while in the load event itself, I need to count grand total amount from a single datagrid column and add it to a textbox in same page .
My page looks like this:
My DataGrid:
Item Quantity Total
Shirt 2 200
Pant 1 500
Tie - -
Belt 2 100
My Textbox ---> Grand Total amount : - 800
How do I do that if I am counting from a ((Total Column )) DTG
And adding it and showing it in my (( GRAND TOTAL AMOUNT)) TEXTBOX
I have a datagridview in my project that is loaded with data from a SQL table when the form loads. One of the columns contains names of users in the database. I'm wondering what is the best way to the number of times a name appears in the column. For example, the user name "Rob Smith" might be listed 12 times in the column,I'd like to pass that number to a textbox.
View 3 RepliesI have a DataTable that has several hundred rows.I want to get a row count of distinct values in a particular column.For example, I have a DataTable of Product Orders, but I want to get the number of unique Customers.
I was using this code, but I can't rely on it because my binding source is filtered from time to time.If my binding source has filtered out all rows datatable.DefaultView returns 0 rows.
I have a table with the below structure.
ID VALUE
1 3.2
2 NULL
4 NULL
5 NULL
7 NULL
10 1.8
11 NULL
12 3.2
15 4.7
17 NULL
22 NULL
24 NULL
25 NULL
27 NULL
28 7
I would like to get the max count of consecutive null values in the table.
i m trying to run a query on an MSAccess table, but it does not give me any count but only 0.
There are 3 null values which i should be getting but it does not give me the result. This query works perfectly in MSSql Server 2008.
the query is :
Quote:
SELECT COUNT(*) AS Cntr
FROM (Modul m LEFT OUTER JOIN
Relation r ON m.Mod_Name = r.von)
WHERE (m.[group] = '')
I need a workaround for this but am unable to find one.
Problem (1) Basically I got a Sub handling a button click, in the Sub I start my timer. In the timer_tick, a value is assigned to a variable and then the timer stops. This variable at the given time should be used later on the sub, however whats currently happening is that the the timer is starting; but I figured the sub must continue going as the variable dosn't change till the sub ends and then the timer begins to do all its ticks so to say.So basically how would one go about making it so that once I start my timer,for the sub to stay where it is, do everything till the timer stops and then continues.
Problem (2) This is in regards to the timer being broken, basically i'll show my code below. Whats happening is that at "ElseIf county = publicx Then" the timer must be stopping right before, as it's not doing the if statement and in my form nothing is changing and its locked as the timer hasn't finished. In my timer the form should unlock before finishing, so I know for sure its not finishing. So whats going on with my timer, why is it freezing on me? Also, for the record @ count=publicx both values are 1 and the countertime=0; so the variables are correct.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
Dim CwStich As Boolean = False
Dim pbName As String = ("PB" & county & publicy)[code]......
I'd like to create a user-defined data type in VB.NET but don't know how to do it.Ta say there's a variable to control the action of a timer control. The possible actions would be "no action", "run timer", and "stop timer." I could do this with an integer (e.g. 0=no action, 1=run timer, 2=stop timer), but I'd rather create a data type so that the options are more explanatory than a simple integer. Like so....
Private Timer_Action as MyDataType
Timer_Action=MyDataType.RunTimer

View 3 RepliesI have a WPF application that allows users to create questions of all different types which depending on the type will use a textbox,combobox,checkboxes, or radio buttons to allow the user to answer the question after they build some sort of questionnaire. My question is what is the best way to keep track of the answers across all the different controls after the controls are created and the questionnaire is created on the fly. Right now, i'm looping through all the containers and getting the values based on the controlType.

I am using VB.Net 2010 and calling a stored procedure with a dataset to get values in a table plus "created" values.
The values for the "created" values do not come across from the stored procedure. They all show as zero in the IDE and False for the variables. I know I am getting the record because the first five values come across from the stored procedure into the variables correctly.
When I step through a VB6 program using ADO the values are pulled across from the stored procedure.
The problem seems to be in the interface between a dataset and "created" fields in a stored procedure.[code]...

The only publicly accessible property gives the logical page count.
