I have the following code which creates a treeview of a folder and files on my PC. The front-end code is the following:
[Code]....
I have following in the code-behind file:
[Code]....
The result is a web page that allows me to navigate down to individual music files within various folders. Beside each music file is a checkbox.What I want to do is select several files and then click a button that will move the selected files from their existing location to another location. I'm running into two problems. One, whenever I add any control that performs a postback, the treeview doesn't repopulate. Two, I don't know how to retreive the values of the checked checkboxes.
I'm trying to find a way to retrieve the value associated with a checkbox on my treeview on the check event. The OnCheckChanged event doesn't appear to work, everyone seems to be using javascript. I can get the thing to postback using javascript ... ideally I just want the value of the checkbox that was selected.

I have a datalist that is bound to a table in the database. I need to have a button for each item. Then, when users click that button I want to be able to retrieve information about that item. I have done this with gridview, but cannot seem to get it to work with a datalist. The only reason I am using a datalist is because I am able to arrange the items how I want and not be forced to have columns.
I use a ModalpopupExtender to show a dialog to the user which consist of a CheckBoxList control that is bound to a session table. The user can check/uncheck the CheckBoxList items and click the Ok control to close the ModalPopUp. How can I retrieve the values of the CheckBoxList items controls using JavaScript (seems like I cannot do it using server side scripting)?
I have a form with 2 sections. The first one contains some radio buttons. The second one contains a checkboxlist. When we change the selected radio button then it modifies the elements in the checkboxlist. For this I setted the radio buttons with autopostback, and in the code behind (in OnLoad) I populate the CheckBoxList depending on the selected radio button.
This work fine.
The problem is that I also have a button at the end of my form which post the data of my form in another page (with PostBackUrl). Then in that page I would like to retrieve the values of the checked checkbox. But I can't find how to do that. In the Request.Form I don't see anything.
I searched on the web but I didn't found really a solution.
I'm populating a dropdown box bound to an sqldatasource. From the sqldatasource, I'm retrieving locationID,locationType and LocationName.
The locationName is displayed in the dropdown. The selected values is set to, "locationID'. Based on the 'LocationID' the user is directed to a new page.
However, I need to pass the "locationID" and also the "LocationTYpe" values for the selected Name, so the sure can be directed to a specific page..how do I get BOTH values, 'locationID' and 'LocationType' when the user selects 'Location NAme' from drop down.
I populate web form with dynamic list of exams from database. I want user to enter examination marks for each exam. There is list of exam titles and textbox near each title.I create list with repeater control (ViewState is disabled)
class Exam { public int Id { get; set;} public string Title { get; set;} } ... // this list is retrieved from database actually Exam[] Exams = new Exam[] { new Exam { Id = 1, Title = "Math"}, new Exam { Id = 2, Title = "History"} [code]...
above string i have displayed in front end thrgh response.write i.e by assigning string abc to viewstate. also i am tryin to genetrate above input fields from database , so i have to make it dynamic in a loop. so when a user updates any of those dynamically created fields i need to retreive those values in a loop

field1.text , field2.text ......so on till fieldn.text ....i want to assign these values to array

string[] arr1 = new string[nooffields]; arr1[i] = fieldi.text;
The method has a return type of collection<businessEntity>, i am calling the method from the aspx page in order to populate a drop down -> ddlDropDown. I am binding he DataTextField of the ddlDropDown with the BusinessEntity.Name and the DataValueField with BusinessEntity.Id, the business entity contains another id which is BusinessEntity.ProductId. I need to use the ProductId of the value selected in the drop down list in the code behind.
One possible way could be to call the method in the page_Load on the code behind and save the collection in a hidden variable and when required do a loop through in the hidden variable and retrieve the selected value Product Id.
am using C# .net.. in my page am having nested repeater control.. in child repeater there is check box and a hidden ID. i want to store(here am get strucked) the ID of checked box in to my data base.. look at the below code..
how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
[Code]....
Here's another issue..I can't even assign values to the checkboxlist using databinding..so how am I suppose to do this.. Server Error in '/ArchitectView' Application.

how to retrieve a value from a typed dataset. I am trying to retrieve a value from a row within a row return from a tabale adapter method. Example:
Dim transAPI As New PN_TransactionBLL() Dim trans As PN.RetrieveGEmailDataTable = transAPI.getGEmail(itemtId)
The tabeadapter method retrieves 1 row of data and I would like to pull the values retrived such as "trans.rowproperty"(if thats the correct syntax) where "rowproperty" would contain the actual value returned.
