however, on the server side (after postback) I can't read them from the Request Object. How do I "mark" them so I can read them at the postback?
protected void DeleteSelection_Click(object sender, ImageClickEventArgs e)
{
int multiIdsToDelete = Request.Form["multiCheck"]; <-- In the Future will be added to an array so I can do the delete for each row selected.
}
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
i am desigining an application where i m creating checkBox (not checkBoxList) dynamically. There is one master check box that define group if i click that it should click all subCheck box under it.I am using ajax in my application.i am able to generate check box at runtime but not able to find its event here is the code for creating check box and its event.

I have created one user control in which I have taken a gridview. Columns of this gridview are getting generated dynamically. (i.e. I read Column name from Xml file) But now I want my first coloumn of this gridview as a checkbox field.
Im basically listing a set of facilities in a datagrid. Like so:b Projectorcb Laptopcb TelevisonIn roomview, a check appears where a facility is availble in a room. This part works fine.The user can then edit the facilities, by clicking on the check beside each facility. When the update button is pushed I need to record the value of the checkbox, however I cant get the value of the checkbox.eres my codebehind:
I am beginning to write a dynamically generated, database driven form. It will be split into several sections, each section having a "next" button, that will save the current section and proceed to the next.
Ive not begun yet but as its generated dynamically this will all be on the same page and either postback, or redirect to itself and the questions will be loaded into a repeater, choosing the input type based on whatever in the database.
My problem is that one section of the form works slightly differently.
I need to ask all the names and birthdates of everyone who lives with you, so I would need the form fields, an input button and then when pressed save the data and load into a repeater, which will have its own delete button as itemcommand.
Im dynamically creating several dropdowns onclick of a button... but the dropdown returns null when im trying to get the values on submitting the form... i read tat during postback all dynamically created controls will be lost... s there a way to register the controls... i want to access the item selected in the dropdown .... expecting a positive reply...
I have a page where i am creating a number of <span> elements using clientside code.
I am creating the elements using jquery like this
[Code]....
But this returns a null object everytime. I have tried this code on a span that is on the page at the beginning and it works so i guess its something to do with how im creating the control dynamically.
Oracle has simple, useful and free tools for attaching to a process and monitoring its SQL statements but I can't anything similar for SQL Server. This is incredibly useful across a number of scenarios, particularly when dealing with third-party assemblies (1). ANTS 6 seems to support something like this (2), though it doesn't allow you to view the stack-trace that lead to the query as dynaTrace does. I don't think dotTrace tracks parameter values, either.
Surely there's a widely available option for profiling SQL application-side?
- How can I uncheck a checkbox using client side code when the other checkbox is checked? - Is there a way to check server side on form submission that at least one check box is checked?
I'm very much a newbie to ASP.Net and am getting the "a page can only have one server-side form tag" error. I have searched the internet for clues, but my understanding (or lack of) means I can't adapt other peoples solutions to resolve my problem.My master page has the following code:
Is it possible to use AJAX and an update panel and create server-side controls such as checkboxes, buttons, and radio buttons (asp server side) that is created when another server-side control (that which exists outside the update panel) calls them?
secondly, how do you keep them from re-appearing after a postback?
When I do a postback, the controls in the update panel disappear.
I have a button that does a postback to server then back to client and finally to the action attribute of the form element.When the page post back to the client the onload <script>document.frm.submit()</script> finally submits the form to the action attribute of the form.I would like to eliminate the unnessasay post back to the client.Below is the code the runs on the server.
I was wondering does anyone know how to save a file to the sever without using a fileupload? What I have is a file that is dynamically created as a .CSV file. Here's that part of the code:
[Code]....
How can I save that to the server instead of poping up a Save/Open dialog box?
I have created table into database dynamicaly,while inserting records into that dynamic table i faced problem.
The name "STD000001" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. this error occured.
I created dynamic table by ,
declare @STUDENT_Table varchar(50) set @STUDENT_Table = [dbo].[GetStudentTable](@SchoolID) exec (@cmd) [code]....
this stored procedure.....
Should i give any permission while creating dynamic table.
I've created a bunch of asp:hiddenfields dynamically at runtime in an asp.net page.
My question is this:
How do I find those hidden fields?
I have an event attached to a control that fires a javascript function, and that's where I am attempting to use JQuery to find the hidden field associated with that control.
Ok, so I'm dynamically adding <input type="File" />'s to the page via button click, client-side via Javascript.
Now when I click the upload button I can access the PostedFiles server side, but I also have radio button lists that I've created dynamically as well with no runat="server".
If I were to .setAttribute("runat","server") for the radio lists I create, is there a way to access that client-side created server control, from the server side?
I am using C# ASP .NET MVC and ajax calls. I am able to get the display of the table along with all features. But, I don't understand how do I add a checkbox and button. I have tried dom-checkbox as well but can't get it to work.
I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1 'use a try to target the button, use catch to handle if it's instead a label, only one cell per row. Try Dim accountLink as Button = tblAccountList.Rows(x).Controls(0) Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck Catch ex as InvalidCastException Continue For End Try Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
