I need to loop through a list of check boxes when the user clicks an export button.
The check boxes are in a panel and depending on what check box is checked I export the tables to excel.
Here is the code.
[Code]....
What happens is it exports only the first checked box to excel and then stops.
What am I doing wrong? I need to export all the checked checkboxes to separate excel files.
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.

View 4 RepliesI 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 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?.
View 5 RepliesI 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?
View 2 RepliesI 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 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
name address class selected
name address class selected
then when they submit, I insert
name address class selected
name address class selected
one row for each in permanant database
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.

i have repeater

when i click chk_packages checkbox myCheckedChanged fired and i want single checkbox to get enable
I am displaying my table data using listview control. It is working fine.
Now I would like to add a checkbox in front of every item so then when user checks the checkbox and click on delete button inside or outside the listview control then i want all the records to be deleted.
I am having a problem with this code, i had a post on this however this code is slightly different to that so i thought i would post a spearate thread.
Anyway, what i am trying to do is display job vacancies by the result of a DropDownList value. Now each job name has a description. The problem i am having is i need to display the results in this logic:
Job nameJob descriptionJob location. But what is happening is the job description (body) is repeating the more vacancies there are. This is the page:
http://kidsunlimited.co.uk/vacancies_test_two.aspx
If you select Deputy Nursery Manager from the DropDown and hit the Search button you will see the results. After listing the first two locations the description is repeated and then the 3rd location is shown after this. This is my code:

I have the following function that translates the header row in a gridview:
[Code]....
When I added sorting to the gridview cell.Text does not work anymore. How can I access the header text in the cell?
I am using asp.net panel control in which I am adding two controls(a literal that contains some text and a checkbox) in code behind.
The code is something like this....
CheckBox checkBox=new CheckBox();
checkBox.ID = "chk_id";
checkBox.Text = "chk_text";
pnl_cityNames.Controls.Add(checkBox); //add check box
pnl_cityNames.Controls.Add(new LiteralControl("Some Text<br>")); //add some text
and to retrieve I am using this code.....
foreach (Control var in pnl_cityNames.Controls)
{
if (var is CheckBox)
{
int abc = 0;
}
}
When I run this code in the debug mood, It shows two added controls
1.)Text="Islamabad" checked=false
2.)System.Web.UI.LiteralControl
This is what the problem I am facing, it should add checkbox in the same manner as LiteralControl. So I am unable to get any condition to be true when I check the var for CheckBox in the foreach loop.
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 have a situation where i have unchecked all checkbox from a panel which havs some nested panels. I am able to clear checkboxes from main panel but nested panel's checkbox remain unchanged. My code is

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.
How would I loop through controls on a content page to set allowreorder of all reorderlists to false.
View 10 RepliesI'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.
