i have the requirement that to set the 'Timetable' for school..
i need weekdays vertically and periodnames horizentally as headings in the gridveiw.. and with in the gridveiw the client can able get those many periods dynamically with in the dropdown....
I have a database with some data in. Now I'm trying to show that data on my page whit a ListView.
For each object from the database a ListView will generate a dropdownlist.
I also have a DataPager on my page and this is where the problem occurs.
Each object generated from the database has a field that may look like this example.: 1,2,3.
In my code now I´m trying to split this string of comma character and add new items to my dropdownlist.
This works as long as I do not have DataPager on. But if I choose to view an x number of pages at the time when the page loads, I have value in the dropdownlists, only on my first page.

In my code behind (c#) I dynamically created some RadioButtonLists with more RadioButtons in each of them. I put all controls to a specific Panel.What I need to know is how to access those controls later as they are not created in .aspx file (with drag and drop from toolbox)?
I tried this:
foreach (Control child in panel.Controls)
{
Response.Write("test1");
[code]....
"test1" and "test2" dont show up in my page. That means something is wrong with this logic.
I have a GridView:

I have this LinkButton in the ItemTemplate section... I want to add a jQuery Popup when the user will click on it. The message that will be displayed depends of the value in the label. Is there a way I can do that?
I have it setup so that when a user selects an item from a DropdownList, that some DropdownLists are dynamically created, based on the results from the Database that are returned after selecting the item in the first DropDownList.
Then, I have a button that takes the data and saves it to an object I've created for this, and I try to iterate through the Controls of the Placeholder that I added the DropdownList controls to.
However, the Placeholder says there are no controls in it, when I press the button, but I can obviously see them there.
Here is some code:
When a "Pilot" is selected, I get all of the Upgrade Types that that "Pilot" has access to, then I create a DropdownList for each type of Upgrade with all the actual Upgrades of that Type:
VB Code:
For Each u As UpgradeTypeList In upgrades     Â
Dim lbl As New Label     Â
Dim ddl As New DropDownList      Â
ddl.AutoPostBack = False      Â
[Code] ....
Then, when the "Add Squad Member" button is pressed, I am trying to iterate through the controls, pick out any DropdownLists and get the values from them and add them to a List Of in an object for the Pilot info:
VB Code:
Protected Sub btnAddSquadMember_Click(sender As Object, e As EventArgs) Handles btnAddSquadMember.Click Â
For Each c As Control In rowUpgrades.Controls     Â
If TypeOf c Is DropDownList Then       Â
Dim DoesExist As Boolean = False        Â
[Code] ....
But, the controls supposedly don't exist and no values get added to the List(Of).
I am dynamically creating controls from javascript. Now i want to access this is server side.
I assigned all the control values from dynamically created controls to hidden field and accessed that in server side. For this i need to create many hidden fields as much as dynamically added controls.
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 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.
i have a link button which i have created dynamically and added it to a div i want to access this link button in some other function in code behind how to do this

View 1 RepliesI am using cascading dropdown list where the no of dropdowns is created dynamically on the page. The cascading drop downs are contained in a User Control. I need to call a method from the Parent page which will be executed when the values in one of the dropdowns change. The server side event is not firing as I have set AutoPostback property for the dropdownlists to be false. How can i make the Page event fired from the Selected index changed of the dropdowns keeping the autopostback property to be set as false.
View 5 RepliesWhat I am trying to achieve:I am trying to take the value of the selected index and depending on what this value is (e.g. the case selection in the code below) run a different query on the dataset and then create a repeater control dynamically to output each row with an item template
that I can use css to style.
In other words: When a user choses a list item it shows only rows from the dataset that match the list item chosen. For example if a user choses Closed Tickets they only see rows from the dataset that have a STATUS of 'CLOSED'.
What I have done so far: [Code]....
What I'm struggling with at the moment is:
1) That the case selection works but the selection of the appropriate data from the dataset doesn't seem to be happening. And this data isn't getting stored in rows as I had hoped.
2) I'm not sure entirely how to display the dynamically created repeater control in the admin.aspx page.
I have a page that I am creating 5 separate GridViews on, depending on the button the user clicks, a different GridView will show up. On a few of the GridView's there is a need for paging, so in the CodeBehind I did the following

I am new to asp.net. I am trying to display some data from a database table using dynamic table in my page. I want to add checkboxes to a field in the database and would like to perform several tasks based on the values checked. The checkboxes are tied with the primary key field of the database. Here is the code snipet :

Now I have a button in my page. The functioanlity which I desire is on clicking that button I should be able to extract the values of checked checkboxes and perform some function.
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.

View 3 RepliesI have a listview control which is created dynamically, it is nested inside a repeater's itemtemplate. I'm trying to attach a datapager to it, which is also created dynamically but the datapager will not display and the listview will just display all its records in its entirety.

I have a menu. I use the menu's menuitemclick event to create a gridview (several actually) that is then added to a panel for display.The gridview paints perfectly until I try to add paging.I have successfully used paging and sorting declaratively for years, but this is my first attempt to do everything in code.When the gridview tries to databind, it throws an error:
[NullReferenceException: Object reference not set to an instance of an object.]

I am creating a project that dynamically creates radiobuttons. So far, i'm done with creating those radiobuttons dynamically. My problem is getting the values from those radiobuttons. To get those values, I need to click the submit button, however it seems that the radiobutton value or the radiobutton itself is lost after I click the submit button.
here are my codes, though not my exact codes, it follows the same logic...
protected void Page_Load(object sender, EventArgs e)
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 gridview and dynamically creating columns and bounding using datareader source.
HyperLinkField hFld = new HyperLinkField();
hFld.DataTextField = dataReader.GetValue(1).ToString();
hFld.HeaderText = "Doc No";//dataReader.GetValue(2).ToString();
i want to to replace the hyperlinkfield with a template field that contains a hyperlink WITH ID where hyperlinkfield does not have ID and be bound to the same datasource above because i want to make the abililty to set the navigate url attribute using rowdatabound
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink hFld = (HyperLink)e.Row.FindControl("hyperlinkID");
lnkTicket.NavigateUrl =

}
