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.
View 3 RepliesI added dynamic checkboxlist.The javascript validation for checkboxlist(dynamic) in firefox + asp.net is not working,but in IE its working fine.why the javascript validation is not firing for dynamical checkboxlist.
View 1 RepliesI 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.
My code which create dinamically button is here:
Button btn2 = new Button(); btn2.ID = "btnEdit"; btn2.Text = txtKategoriEkle.Text; btn2.Attributes.Add("OnClick", "btnEdit_Click"); btn2.Attributes.Add("onclick", "my_javascript_function"); form1.Controls.Add(btn2);
I need to charge my checkboxlist1 from database, eg load fruits and vegetables. When selecting fruits, new filter based on the previous selection in my checkboxlist2. for specific search.

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 can add the dynamic textbox in dynamically created html but can not get the value of dynamically added textbox.
there is code what i do
protected void txtNoOfTypes_TextChanged(object sender, EventArgs e)
{
int n = Convert.ToInt32(txtNoOfTypes.Text)+1;
for (int i = 0; i < n; i++)
{
Label MyLabel = new Label();
MyLabel.Text = "Type" + " " + ViewState["num"] + i + " " + ":" + " ";

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:
if ($find(MPIDList[clientID]) == null) {
$create(Sys.Extended.UI.ModalPopupBehavior,
{ "BackgroundCssClass": "modalBackground",
"CancelControlID": CancelControlIDList[instanceId],
"DropShadow": true,
"X": 50, "Y": 250,
"PopupControlID": PopupControlIDList[instanceId],
"PopupDragHandleControlID": PopupDragHandleControlIDList[instanceId],
"id": MPIDList[instanceId]
}, null, null, sender);
So I was trying to do the following:
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 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/
View 1 RepliesI am binding a checkboxlist with a dataset (with these columns :
id,empname,resourceId,balanceId as columns) with datavaluefield as id and datatextfield as empname;
Now, i want to control the selection of the items. Say some thing like
1. "User should be allowed to check only say 5 items with same resourceId" using javascript
2. And in total he should select only 20 items (max 5 items for same resource id and max 15 items for the remaining)
How can we control this?
I have a custom control with four checkboxlist(Country, City, Outlet, Stores) controls in it.

I have a checkboxlist control showing Q1,Q2,Q3,and Q4 and with AppendDataBoundItems="True" I added:-

Platform: ASP.Net 2.0 I have multiple checkboxlist controls on a webpage. Along with that i have the same number of buttons on that page. Initially all the checkboxlist controls are hidden. When user clicks on a button, corresponding checkboxlist controls gets visible making others hidden and allows user to select the options.
On postback, if user clicks on the same button again, the corresponding checkboxlist gets visible but the item selection is not retained. However, this happens only in IE. This works fine in FireFox. I am using JQuery to toggle the visibility of checkboxlist.I guess the problem is because i am toggling the visibility of checkboxlist which IE doesnt seem to like. What is the solution to this problem?

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 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 dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.
For example If I select Gujrata then all the cities of Gujrat should be visible and bounded to the check box list.
2) Once the checkbox list is bounded with data from the database, We need to select the checkbox from the checkboxlist and pass tyhe selected text of all the selected checkboxes fro the checkbox list as comma seperated values to database and then I need to Display in the Grid.
Below is my code for Dynamically populated/Bind DropDown list and get the States:

Is it possible to save selected items in a gridview for future purposes?
let say i have a gridview, from all items selected in the gridview I want to give the user the possibilty to save the selected Items,.
in this case the items is data of persons, name adres, email etc. If the data is saved (for instance in a textfile) it should be reusable the next time. so a user can choose again a selection frmo the gridview or can load the earlier saved list.
How do you save a radio button selection to a DB (within the .aspx page)? I have 5 sets of "yes/no" radio buttons (1 for yes/ 1 for no). Do I just add each radio button as a field into the DB and if its not selected, leave it NULL (or whatever the default value is)... this does seem very efficient.
View 1 RepliesI 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.
