Web Forms :: How To Save Dynamically Created Buttons In Database
Apr 16, 2013
I created a web site with admin control with C# ASP.Net. Admin can create a new button1 with button2.I did this. but when admin login again the created button is not seen.I guess I should save this created button at SQL Server but how should I do.
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.
m new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button,

i have followed this article and created dynamic rows in gridview on button click: URL....Now i want to save the dynamically created rows data in database/
I was wondering how about may I save the selection of the checked items of a dynamically created CheckBoxList?On postback the entire checkboxlist is lost. As the CheckboxList items are manually added in and not databinded, the selection is also lost.I was thinking of javascript, but i'm not sure how to implement it.
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 am using the code below to recreate a modalPopup window. At each UpdatePanel refresh I "lose" the window but I recreate it again after my Panel is updated. This gives me the impression that the windows is always open. The only problem is after I drag and drop it to a different location, the window is recreated back in its original location:
1 - Initialize a global var for X and Y with the static values of 50 and 250;
2 - Show the window and drag it to a different location;
3 - UpdatePanel is refreshed and my Gridview is data bound with new data
On step 3 above I need to find a way to save the current window position BEFORE UpdatePanel is called and apply the saved position AFTER the UpdatePanel call is finished.
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 generating barcode image dynamically on button click .
The image is display on the asp image control, now I want to save that image in database
string barCode = txt_ID.Text; using (Bitmap bitMap = new Bitmap(barCode.Length * 40, 80)) { using (Graphics graphics = Graphics.FromImage(bitMap)) { Font oFont = new Font("IDAutomationHC39M", 16); PointF point = new PointF(2f, 2f);
I have a modalPopupExtender in my aspx web page pointing to a Panel and in Code-Behind I create buttons which I want them to show the modalPopup, so I have:
I have a writing a web page that will use several different types of control. The control types will depend on the data being read from a SQL database. The following is my code that decides what control to add to the page:
Select myReader.GetString(1) Case "DatePicker" Dim bdpAnswer As BasicFrame.WebControls.BasicDatePicker = New BasicFrame.WebControls.BasicDatePicker() bdpAnswer.DateFormat = "dd/MM/yyyy" divAnswerContainer.Controls.Add(bdpAnswer) Answers.Controls.Add(divAnswerContainer) Case "DropDownList" Dim ddlAnswer As DropDownList = New DropDownList() divAnswerContainer.Controls.Add(ddlAnswer) Answers.Controls.Add(divAnswerContainer) Case "RadioButton" Dim rbAnswer As RadioButton = New RadioButton() divAnswerContainer.Controls.Add(rbAnswer) Answers.Controls.Add(divAnswerContainer) Case "TextBox" Dim tbAnswer As TextBox = New TextBox() divAnswerContainer.Controls.Add(tbAnswer) Answers.Controls.Add(divAnswerContainer) End Select
I'm making a custom modal popup using a bunch divs where the programmer can set how many buttons thay want to apprear on said popup programatically using a function. It works. The only problem is that when the programmer specifies the number of buttons he/she wants it wipes out the skin information for the whole control. If I comment out the call to CreateChildControls the skin works fine, but the new buttons are not created.
In my CreateChildControls function the first thing it does is call Controls.Clear(). I assume this is what's wiping out the skin information, but it's kind of necessary to prevent controls with duplicate IDs.
My application I am using pagination.Using pagination i bind the records with listview control.
I generate the buttons dynamically according to the number of pages which is calculated from number of records returned from dataSource.when i click on a dynamically generated button its corresponding event handlers methods should get evaluated.Since asp.net page is stateless I can't keep the state of that dynamic controls after any postback.
Just Now I have seen the Article "How to get the Id of Control that cause postback in asp.net?". I got some idea from that article. Any example for "Creating link buttons dynamically and handling its corresponding event handler in Asp.Net".
i am working on a site where client wants to add the pages from the admin panel to existing website( from the web browser) but static contents like text etc.
I'm creating 14 textboxes for every day in a month and user can select the month so i have o create them dynamically. But i can't reach the values in the textboxes.
I have a tree view with checkboxes for leaf nodes. If i click on checkboxes, I am creating some html controls dynamically. And in other static button click event I need to get an ID's of those dynamically created controls.
