View 1 RepliesI have a listview with paging. Every paging has 10 rows with with a username, an email and a checkbox.
I need to be able to check a couple of checkboxes, in different "pagings", press a button and send an email every to ever user that has been checked.
Trouble is I don't really know how to remember the selected checkboxes between each paging-press.
Deos anyone have a similar solution or a few tips on how to do this?
I'd prefer to solv this without jQuery, but ordinare javascript or a C# solution works fine.
I got a checkboxlist in which I bind the items with data from the DB.Means the rows in my table re directly bind tochkboxlist to display as the 7 listitems in it.Together with that am binding the state also(ie,whther it is previously checked or not by the user).Now the user have the option to edit this settings by checking or unchecking the listitems in it.We need to update this in the DB accordingly.
I need to pass the Id's of the checkd items separated by a "|" along with the state 1 or 0.Meaning if the user check 1st threecheckboxes in the list my parameters shud be (userId,1|2|3,1|1|1)..I tried in the below way..
public
void UpdateNotificationSettings()
{
NotificationDO notifyDO =
new NotificationDO();
[Code]....
I have a treeview and a button.
OnPostBack I wish to know what are the selected categories. also, I need to give a spiciel ID number for each checkbox when data is binding.
i have used a gridview and checkbox to select the items in the gridview....I can select the values easily...when i am selecting one row at a time then using query string i can easily pass the id of the selected row but when i am selecting multiple rows in the field,i dont know how to pass the array of integers[i.e id value to another field]...
here is a part of my code...this is the html code..
[Code]....
I need to check if ANY of the checkboxes are selected from the gridview.. if atleast 1 is selected, then continue, if none are checked then return the error message so they can make a selection, below is what i have.. if i have all checkboxes checked, then everything works, but if i only have 1 then it doesnt work..

I know this not the right place to ask javascript related questions.
But I dont understand how else to get the answer.
I have built an application using asp.net 4.0 and entity framework. I have implemented the routing feature introduced with the .Net 4.0 version.
Now, I have a page which will fetch products from the database and display them in a listview. For the paging purpose I have used the DataPager.
I had a really hard time making the paging feature work with DataPager as it is not fully compatible with the Routing feature(asp.net 4.0).
Now I want to give the user the option to select multiple products to compare. For this purpose I have placed a checkbox with everyproduct.
Now the problem:
I dont know how to find which checkbox was selected. i want to find the checked checkbox using javascript.
I have binded the list of products to the listview at two occasions; once directlly to the listview in page load and second time during the pre_render event of the dataPager. (As I said I had a really hard time to get this combination to work; Listview+DataPager)
Is there a way i can send multiple documents to be printed by looping through a gridview with checkboxes?

how i can accomplish this? I need to loop through the GridView and Print the documents which are located in this directory:
[URL]
The document i want to print is in the SELECT, see [cv]..
So a typical document will be located like so:
[URL]
I want to count the data rows of the selected data and display it into Label.
View 1 RepliesI have Grid view control in the page. Enable paging option is true.
Columns in the Grid view are ID, Name, Checked and Email
Whenever user selects the check box then I am showing txtEmail in the Email columns so that I can enter email id in the textbox.
Like this I am selecting checkboxes and entering values in the txtEmail when I go to next page and comes back. Then these entered values are cleared.
How to keep the textboxes values and checkboxes selected during paging?
I have been doing R&D for 1 day. Tried to implement.
I'm trying to build a list of checkboxes, each one with a textbox/textarea associated to it. The plan is for it to look something like this
[checkbox]

The title of each checkbox & textbox will be populated from the database. I'm not really sure how to go about doing this.

I have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.
My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.
However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.
is there a way to prevent the user ented text from being inserted into the bombo box?
