I have a form with 24 textboxes incremented by a letter. example: txtDimVala1.text, txtDimValb1.text, txtDimValc1.text, etc. I created a code to check each textbox, but there must me a more efficient way to loop it. I have tried a few loops but I cant get them to work looping through the different textbox values.

I am using datarepeater to display rows of information from database. When i click a 'save' button and i would like to loop through the rows of data in repeater. The code i am using is able to do all these. The only problem i encountered is at the Interface side. When i am looping the data-repeater. The selection 'frame' (refer to the picture point as 'A') is moving from record to the next record and scrollbar is auto moving as well to scroll to further down until the last row where looping finish.Is there anything can be done to remove the selection 'frame' and stop datarepeater from scrolling while looping the datarepeater.

While user enters character "w" then "w" should appear in the textbox.Now if user enters character "h" then "wh" should appear in the textbox .Now suppose user enters character "e" Then "wh" should remain with a beep means "e" should not be written in the textbox.
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 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.

I am making a program that uses the datagridview control for making the sales invoice and I want to add direct values from textbox control to datagridview. But the problem is I am not getting the row, col index properly and if I use:
dgv.item(0,dgv.rowcount -1).value=textbox1.text
Then the value goes to the 1st col and 1st row. When I use dgv.rows.add() then value goes down to last row of the dgv control.
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'm trying to loop through a bunch of checkboxes I have created on my aspx page. I would like to get all the values, and parse them to a string to send to another page as post variables. This is what i have so far:
aspx page:
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox0" runat="server" /> Name</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox1" runat="server" /> Training Year</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox2" runat="server" /> Continuity Clinic</div>

aspx.vb file:
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Submit.Click
Dim targetURL As String
targetURL = "report.aspx?"
' This is the part i can't figure out.
' For Each checkbox on page
'if checkbox is checked
'targetURL &= checkboxid & "=true&"
End Sub
My goal is to build another page that will then check these values using Querystring variable, and build a listview out of them. (a report page, that basically lets the user select checkboxes of the columns they want to see on the report).
I have been out of the VB game for awhile and am now trying to catch up to VB.NET. I know my current solution probably has a more efficient way of doing what I want, such as using LINQ or something. But, I am start at the bottom and working my way up. I essence I have 1 table controlling which columns get added to a working string, that I will eventually export into a text file. My first table has 3 columns(ID, String, Processed). The ID is the index or primary key and the string is the data I need, and Processed tells me if I have extracted that string yet or not( 0 for no and 1 for yes)...
My main problem is checking values in table 1 where I need to add the string. Of course my problem might be deeper in how I am even returning the values from the datatables.
Code:
Partial Public Class StoredProcedures
<Microsoft.SqlServer.Server.SqlProcedure()> _

Am trying to add an 'odd' class to a table row in a repeater control..
<tr class="<%# If((Container.ItemIndex % 2 == 0), "even", "odd") %>">

I have a question related to asp.net and vb.net. I have a repeater control that I bind some data to and allow users to update/change fields within certain text boxes.

I am trying to bind a dictionary to a repeater control. I have a dictionary object which is filled with the Key (as String) and values as (Class object).

Something similar to that.

So I currently have a aspx page that shows details for any single staff member, and the page is setup with mostly ASP labels. I have a subroutine called "getstaffdata" that populates the page on load (via subroutine).
I would like to convert this to a page that shows details on one staff member, or many staff members, one after another. So I thought of using the repeater control, but I'm not sure how to convert the page over. The staff userids are passed via query string, but I'm just confused on how to do the datasource for the repeater control.
I have the following repeater
<asp:Repeater id="weatherFeed" Runat="server"><ItemTemplate>
<asp:LinkButton runat="server" id="PickInfo" onClick="Selection_PickInfo">
<img src="images/mapPin.png" title="<%#Container.DataItem("city")%>" />
</asp:LinkButton>
</ItemTemplate></asp:Repeater>
I'd like to call my function "Selection_PickInfo" using the Link buttons created, but I'm having the issue of not being able to actually pull information from these links.
I'm writing a Repeater Control in an ascx file which renders some info as a row that comes from a complex search. In an aspx file I have the query to retrieve a DataView that gives me the XML string with the info needed to feed the Repeater. The problem is that I don't know how can I pass the XML string (or the DataView or DataSet) from the aspx to the ascx file so as I can render the info.
