We are creating html Table dynamically on the basis of data fetched from database and assigned id to each Cell while creating them dynamically. But the problem is how to access values in Cell. Because we are not able to get id of Runtime generated TD.
View 2 RepliesI have an html table with rows and cells. And I have dynamically created a label and would like to assign the label to one of the cells of the table. What I am doing is I have a JavaScript which executes a code behind method and it would not accept an already created asp.net label. So I have created the asp.net label programmatically but cant assign it to the table to display the text value of the label. Below is the code:
[System.Web.Services.WebMethod] public static void EndCandiateTest(){
try { totalTestMarks = ts.RetrieveResults();
grade = tsp.RawScoreAndGrade(totalTestMarks);
remarks = tsp.ScoreInterpretation(totalTestMarks);
testResults = "Raw Score: " + totalTestMarks.ToString() + "
Grade: " + grade + " Remarks: " + remarks;
ts.ShowResults(testResults);
} catch (Exception e) {
} }
protected void ShowResults (string results). I want to display this label in an already existing html table.
messageLabel.Text = results;
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.

View 3 RepliesI'm creating some linkbuttons dynamically and assigning properties like below. Also I'm adding an event handler to the created link button:
[Code]....
What happens here is when the links created at runtime are clicked, most of the links are linked to other applications. (e.g from app1 to app2, app1 to app3 etc..) So when moving from the current app to the next I want to abandon the current session. However, this event is not firing before navigating to the next page. Could someone suggest a workaraound or the correct way to accomplish that?
What 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 dynamically created address user control (on a customer administration screen) that is created through the use of a place holder. A customer can have multiple addresses, so they dynamically dropped onto the page.
I have got this far, but now I need to be able to save the updated addresses for the customer but I can't get any event to fire on the user controls. When I check to see run plhAddress.HasControls() it returns false?
The way I am generating the user controls is as follows.. private UserControl LoadControl(string UserControlPath, params object[] constructorParameters)
im creating a button control in page int and im assing a click event for the button control. here the click event is not firing for the first time. here is my code.

I need to access the controls dynamically created template fields at run time in datagrid in post back event. Is there any way to retrieve the values in post back event? Or else give the ideas to acheive my requirement. I need to create no of rows and columns as text box as per user input. After fill the values to text box , i need to access the values in submit button.
View 1 RepliesIm 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...
View 1 RepliesI'm writing a program that inserts controls onto a webform dynamically. Depending on a variable, I add either a textbox, a set of radio buttons, or a set of checkboxes. Later, after a user clicks a submit button I need to use the controls to determine if the user is submitting the correct answer, but when I try to reference the id of a control, I get "txtAnser is not declared.

View 3 RepliesIm trying to dynamically create a popup control extender for labels which are also dynamically created. the labels are one a dynamically created accordion pane. Here is a section of my Page_Init method:
[Code]....
When I run the site with this code I get the following error:Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.Parameter name: element
I thought it might be because the target control ID changes during compilation so i tried to find the labels in the Page_InitComplete method with this:[Code]....
The expression in the FindControl argument is what the id of the label looks like when i view source in my browser after running the page.I also tried to use the popup control's DynamicControlID property, but im not sure what the DynamicServiceMethod is for.
how to check if a dynamically created control has posted back?The below code is not working.

I have created some imagebuttons dyanmically on page_Init. But the above code always returns null. Why is that? How can I check If an image button has posted back?

I've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.
function setDroppableTargets()
{
$(.cssDockZone).droppable();
}
But the elements with the class cssDockZone is created dynamically upon user interaction. So in the code behind i create the control first and finally at the end i register a scriptblock which calls setDroppableTargets().
//set droppable targets ClientScript.RegisterClientScriptBlock(this.GetType(), "setDroppableTargets", "setDroppableTargets()", true);
But the javascript function is invoked before the controls are created eventhough i register the script at the end (after creating the controls) and i cross checked it by getting the elements with class name '.cssDockZone' and i getting it as 0.
$(.cssDockZone).length
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.
[Code]....
how to set text property assigned to the control created dynamically usiong reflection?
Type type = Type.GetType(strFullName);
object instance = Activator.CreateInstance(type);
ctrlTemp = (Control)instance;
ctrlTemp.ID = "Hello";
ctrlTemp.Text???
Panel1.Controls.Add(ctrlTemp);
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.

View 1 RepliesI'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.
When i don't create them dynamically like
<asp:TextBox ID= "TextBox1" name="TextBox1"> </asp:TextBox>
I can get the value from the C# side by using the
((TextBox)Page.Form.FindControl("TextBox1")).Text
However this moethod doesn't work for the textboxes that i created dynamically. I'm creating them in a loop it's something like;
[Code]....
Then i add the text box to the necessary places at my table.However i can't reach the textboxes when i use the same method
((TextBox)Page.Form.FindControl("!A uniqe ID!"));
It gave a null value...
