On the line where i try and update the InnerHtml, i get the following error; "Cannot get inner content of because the contents are not literal."
I have a tablecell where I import the text from a SQL database and this all works well, except that the carriage returns are not being displayed in the text.
I have done some googling and although I do not get any error messages, the carriage returns are not appearing in my table cell.
Here is the code:

I have also tried Environment.NewLine, etc. but all to no avail.
I've got a text box on my page called txtNotes - multiline textbox.
When I add the text into the sql server database, the line feeds are not getting entered.
I have a function that replaces the line feeds with "<br>" and it's still all in one line. Also I don't see the normal square type entity after each line in the database, that is normally there for a line feed.
However, when I copy from the database and paste it to Notepad, it is formatted correctly

I have tried a number of ways to format the text of a label with codebhind, I don't get errors, but it just ignores the code.
For example, if I put label.text = "Some text " & chr(13) & "some more text"
it will just ignore the chr(13). I have tride vbcrlf, /n, etc.
I would rather not have to change the control to a text box but will if I have to.

View 1 RepliesI have this following setup, a textarea named with some data in it that may have carriage returns and another textarea that has style='display:none' in order to make it hidden as follows:
<textarea id="myTextarea" onBlur="encryptMyData()">
I have an ASP.NET multiline textbox. I can hit return to create carriage returns on the screen but the text property of the textbox is ignoring the carriage returns and simply concatenating the lines without even a space in between. I am writing this text property to a database and I want to be able to retrieve the text exactly as it was typed with carriage returns included.
View 2 RepliesI'm new to .net, and I've noticed that when viewing my HTML source code generated by a .net application the carriage returns are removed from the head tag when it has runat="server" attribute on it.
I remove the runat="server" and the returns... return.
This really looks nasty when you have a few javascript and css files in your header because it ends up making the entire contents of the head tag 1 big line.
Just wondering if there's a way to control this or tell .net through configuration not to mangle the output?
I have an some code to export data form an SQL database to an Excel spread sheet. the data is entered via a web site and some of it contains multiple lines of information. I need to preserve the multiple lines but excel 2007 continues to put an [?] at the end of each line.Here's what I got so far
CellValue.ToString() // this returns [?][?] at the end of each line for excel 2007
// and a single [?] in excel 2010
CellValue.Replace("[//r]","") // this works correctly for 2010 but still leaves a [?] for 2007
Cellvalue.Replace(Environment.NewLine, "") // this removes all the line breaks.
what can I replace the Environment.NewLine with in order to still have line breaks in both excel 2007 and 2010 (with no [?]) ?
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 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.
My Code is:
.aspx
<asp:Panel ID="pnlOuter" runat="server" Visible="false" Width="650px">
<table>
<tr>
<td>
<asp:Label ID="lblQtnrName" runat="server" Text="Questionaire Name"></asp:Label>
<asp:TextBox ID="txtQtnrName" runat="server"></asp:TextBox>...
I need to create web controls (e.g. label etc) dynamically.The problem is that for example,
on my onload event, I create a label. The text of the label is read from one line of a xml file.
But sometimes the text should be like " Messages (4)", in which the message count is something not generic and need some logic to calculate. I tried to put things like "Message (<#% MessageCount %>) " in my xml file, but the displayed text label is:
Message (<#% MessageCount %>) instead of Message (4 ).
I was looking through my transcender exam kit for 70-562 and they say load dynamically created controls in the loadviewstateEvent. This should be CreateChildControls() instead, no?
View 1 Repliesi create textbox dynamically (not in page_load)

I am building a webform dynamically but when I go to get the values the placeholder has no controls. Every control added has an unique ID. Does anyone know what I am doing wrong (language is C#).
aspx page
<asp:UpdatePanel ID="upShoppingCart" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<asp:PlaceHolder ID="phShoppingCart" runat="server" />
<br /><asp:Button ID="btnUpdateCart" runat="server" Text="Update" OnClick="btnUpdateCart_OnClick" />

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.
have some code which dynamically generates a number of drop down lists to provide the user with different options. The items in these drop downlists contain a value which is a unique id for that particular combination of options and a text component which just plain text but not neccessarily unique. I then have assigned a handler to these dropdownlists which is called on selected index changed to perform the relevant actions based on what options are selected. The problem is to make the system perform the correct action I need the unique ID from selectedValue of the drop down box but when it posts back it appears the selectedValue has been replaced to match the text of the item.
Dim dynDdl = New DropDownList()
dynDdl.ID = "ddlOpts" & i
dynDdl.AutoPostBack = True
AddHandler dynDdl.SelectedIndexChanged, AddressOf dynDdl_selectedIndexChanged

dynamically HtmlInputCheckBox created and add in PlaceHolder(panel).
View 2 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
billingGridView.ID = "BillingGridView"
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.
I am giving my code snippet for reference.
This is function to create Grid.

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.

I already have an HTM Table on my form. I dynamically create New Roows and Cells and keep adding them to the Table .
The cells Contain Labels, Textboxes, Drop downs and Buttons. I also add Handlers to the dropdowns
The form loads perfectly the first time. But when I change the value in a drop down, on the postback, I get a msg saying that " There are multiple controls with the same name 'txtCheckin' . How do I handle this?
