Radiobuttonlist - Looping Through Controls In A Table
Mar 21, 2010
i have a table which contains a bunch of dynamically created radio button lists, im trying to write code which will loop through each one of the radio button list and get the text value of the selected item. i have the following code
foreach ( Control ctrl in Table1.Controls)
{
if (ctrl is RadioButtonList)
{
//get the text value of the selected radio button
}
}
but i am stuck on how i can get the value of the selected item for that given control.
How to loop through the table get only paticular records based on the particular value and store it in a datatable.
for example, i've a table with two columns, Store name and Store number. For a single store name it can have mulitple store number like [store name ] [store number] a1 10 b1 12 a1 15 a1 21 b1 11 b1 22 a1 25 etc.... How to loop through the table and get all the records/ rows of a paticular store name and store it in a datatable.
I am trying to looping thru a data table and update a column on each row. However after updating I am getting both before and after update records in the data table. Assuming there is only one column called "Qty" withing the data table and I want to double the value in the column. I use the following to perform updating but not getting my expected result.
I have a radiobuttonlist inside a datalist itemtemplate and i need to bind the radiobuttonlist dynamically from database I have tried to bind it inside itemdatabound event of datalist but it the result is always duplicated according to the fields in teh database.
for more information:
the database has two columns one for questions and the other is for choices , for the first question with id lets say 1 there are 4 choices, when the radiobutton is binded the result appears to be 4 times duplicated ?
Probably an odd question, but I'd like to know if it's possible to have a table with 3 columns and have a radiobuttonlist that spans these 3 columns with 1 radio button per column?Perhaps there's a more sensible way to do this, I've got 3 options that I'm going to pull from a database to populate the radiobutton list with and I want to repeat it "x" times.So imagine a questionnaire with 10 questions, and your only answers to each question are yes, no or maybe, I want something like all of the yes radio buttons in the first column, "maybe's" in the second column and "no's" in the third column (Just to make it look pretty).I know that I could manually put 3 radio buttons in a row, 1 per column, and give them their own ids etc, but that's working hard, not smart :)
This way my jquery is not working, there are mistakes in the part
if ($(this).attr('checked') == true && $(this).val() == "HB")
I tried those two conditions above alone, and they both are not working. I need to reach to my radiobuttons but seems like I can't. Then how should I write that part in order to make my code work.
What's the best way to do this? After I load my DataTable from SQL, I'm looping through it with a For Each...Next loop performing some calculation for each DataRow. If the values don't fall within a certain threshold, I want to remove that Row. However I can't just do a MyDataTable.Remove(MyRow) or it breaks my For Each loop.
I'm re-writing a VS 2003 application in VS 2010. One of the pages loads really slow due to a section containing a datalist with multiple checkbox list and dropdown list. Most of the time used on nested for loops to check if a datalist checkbox should be checked, if the checkbox is checked, then select the appropriate dropdown list option in the datalist. Is there a quicker way of doing this sort of thing in VS 2010? Better controls for this? Would Ajax work?
I have another loop that loops thru each checkbox and dropdown inside of the datalist to determine if the checkbox/dropdown list should be enabled/disabled. There are about 4 of these datalist sections on the page.
I am using a page based on a masterpage file with a content section that does not have access to the form. I was wondering how do I go about looping through the textbox controls on the page, I have tried the following
[code]...
However this does not find any of my controls on the page. I pass in the Me value and it still can't find any of the controls.
I have a ListView which has Product Code,Desc, ColorCode, Size and Quantity as the columns as well as a checkbox
The listbox sits within a panel.
The user enters the quantity and checks the item(s) they wish to purchase. They accept their selection by clicking a button the sit within the ItemView
Once they have made their order and clicked the button I want to make the panel disappear and display the items on the page.
how to iterate through the Listview and how to grab the items and close the panel
I've spent the last three days searching for a reason why I cannot loop through controls on a page link with a Master Pages, and have tried every example found on the web with no joy.
The most resent and the one resource that makes since was found on ASP.Net, but unfortunately it creates an infinite loop and dies. Link for my latest attempt: [URL]
This post was written in C# and I may have missed something in the conversion over to VB shown below.
I have around 100 checkboxes on this page that I am trying to load into a Array List to evaluate on the page code behind when returned by the function.
I need to have maybe 5 threads running which all use the same DataSet and need to loop through all the rows retrieved but each row must be processed by one thread only (e.g. I don't want row 1 to be processed by thread 1 and thread 3).
I can also use a DataReader if that helps, but I need to dow some locking logic I would have thought.
I am curious, if it's better to iterate through a set of records using cursor or using a WHILE (SELECT ..) ? I have read that cursors can be expensive, so may be WHILE (SELECT..) is a better approach.But I am not sure ?
EXAMPLE OF WHILE (SELECT..) is as below DECLARE @warehouseId INT DECLARE @warehouseIds TABLE ( WarehouseId INT )
I am trying to add the checked rows into the database by looping through but im getting this error:

I have two gridview. The first gridview with checkbox and if i check the checkbox in first grid that particular row will be binded to second grid. In second grid i have a textbox and dropdown. Have enabled pagination in both grids. When i check the checkbox in first grid i loop through all records in second grid to bind the previous values. Problem is since i have enabled pagination gridview row count only retuns current page row count. How to loop through all rows?.
I have a Gridview that has Paging enabled, and I need to loop through all the rows of the data. Therefore, I assume I need to loop through the datasource instead of through the Gridview.
I change the datasource of my gridview at various times when running.
How can I get a DataView of the GridView's current DataSource, so that I can loop through it?
Something like:
Dim dv as DataView = DirectCast(GridView1.DataSource, DataView)
except that this comes back as Nothing, probably because a Datasource isn't a dataview.
I know that the datagrid control loops through a database table from the first row to the last, but I want it to loop from the last row to the first. How can I do that? Also I wanted to know how could I drop some rows according to my needs while looping from end to start, so that the datagrid only displays those rows that I need to display?
Looping Through Checkbox List and adding selected items to MS SQL DatabaseI don't want to store it using comma deliminator.I will need to do a search on analyze which users have what music in common.The image above is from a tbl_lookup_music table I created.

This table receives data from my web application via a stored procedure, snippet pasted below:

In my quote.aspx page, I have a wizard control that collects numerous data points. In one of the wizard steps, I have 20 textbox controls for PartNumbers and 20 textbox controls for respective Quantity.
Question:How do I write a for..each loop that checks for values in my Part Number and Quantity fields and inserts them via my SQLDataSource?
I have a gridview that serves as a confirmation for user input in a previous form from a previous page. The grid is databound to a temporary table where I store the user's initial selections. The user can confirm what they had submitted, (which may be more than one row of information, up to three classes) or go back and change. When they hit the confirm button, I loop through the gridview and enter a row in a permanent database for each row in the gridview. This works great.
However, I don't want the gridview to display all of the columns that are actually in the temp database, because I'm carrying over 'usersubmitted, datesubmitted', etc, from the previous page for each class selected and this is redundant. (I do need to use all of the columns when they submit, however, to make a new row with complete information for each selected class in the permanent database) So, when I set the usersubmitted column visible false, for example, in the gridview, the dataset table adapter insert function fails with a data type mismatch error. I'm assuming becuase the column has to be visible, becuase when I make it visible again it works.
Can you loop through a gridview and call on cells in columns that are not visible?
The first page is like this:
the user fills out his info once in text boxes
name ____
address____
then selects up to three classes in dropdowns:
class one dropdown ...
class two dropdown....
for each dropdown, I insert name, address, class selected into a temp db Second page.
Gridview should display only classes selected, one row for each, and not
