How To Check If ViewBag Has A Certain Dynamically Created Property Or Not

Feb 3, 2015

Suppsoe that a certain dynamic property of a ViewBag object is optional. How can I check whether it has been created or not?

My first reaction is to check for null value.

Code:
@if (ViewBag.OptProp != null) {...}

But then how to handle the case when the property has been actually created, but the value assigned to it is null ?

How do I check if an object has a property in JavaScript?. Except mine is about .NET .

C# - Is A New Object That's Created In A Static Property Getter Only Created Once

Jan 11, 2010

I'm creating a static helper class for web services I'm writing. I'm tapping into the API of Telligent and therefore creating these Telligent "service" objects that allow me to do things with the platform. For example, I'm creating a MembershipSerice object in my helper class so I can do membership stuff with the same object. In my helper class I have a property with a getter that creates a new one of these objects:

private static MembershipService _MembershipService {
get return new MembershipService(path, usr, pwd);

Web Forms :: Use Dynamically Created Controls Such As A Checkbox List And Fill The Values Dynamically?

Sep 28, 2010

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.

Web Forms :: How To Use AddHandler To Dynamically Assign Events To Dynamically Created Buttons

Feb 14, 2011

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.

Get Value Of Dynamically Created Radiobuttonlist?

May 24, 2010

I'm trying to get the value of a dynamically created radiobuttonlist via javascript to call a pagemethod.

This is how I'm creating the rbl:

rbl.Attributes["onclick"] = "javascript:preview('" + rbl.ID + "','" + rbl.ClientID + "');";

And this is the javascript:

function preview(controlid, clientid)
{
var radio = document.getElementsByName(clientid);
var answer = "k";
for (var ii = 0; ii < radio.length; ii++)
{
if (radio[ii].checked)
answer = radio[ii].value;
}
PageMethods.SaveAnswer(controlid, answer);
}

The problem however is that I want to get the groupname of the radiobuttionlist so I can use getElementsByName, but i have no luck so far.

Web Forms :: Getting Value From The Textboxes Which Created Dynamically?

Feb 15, 2010

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.

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...

Accessing Controls Created Dynamically (c#)

Jun 5, 2010

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.

Dynamically Created Controls And Postback

Nov 18, 2010

I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control.

When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it.In the aspx:

<asp:Panel ID="pnlFilter" runat="server">

</asp:Panel>

In the aspx.cs:

protected void Page_Init(object sender, EventArgs e)
{
LinkButton lb = new LinkButton(); [code]....

C# - Dynamically Created Textboxes Not Updating?

Apr 4, 2011

I'm creating textboxes in the Page_Load event and giving them values, however whenever I load the details I am getting the same output. I always seem to get the first output I got, even on subsequent searches.Here's what my code with the irrelevant information missing:

Textbox txtName = New Textbox();
protected void Page_Load(object sender, EventArgs e)
{

[code]...

If DropDownList has two values (e.g. "Item 1" and "Item 2") and has autopostback enabled, first time it will generate and show "Item 1" in the textbox (the default value for the DropDownList), but if this is changed and the autopostback fires, the textbox does not change.I've tried getting around this by creating a new TextBox, overriding the "LoadPostData" function to prevent this from loading, which got around the issue there, but then I couldn't view the data afterwards.

Any idea how I could get around this? I may be approaching this in the wrong way.Edit: I've added another item to DropDownList that removes TextBox, so that it can be re-created again. It seems to show the correct data when it is re-created after being removed, but if I'm attempting to just edit it, this isn't updating correctly.Edit2: Here's the rest of the code for this page in case this helps at all. The objects which I'm having issues with are SBUName and SBUComments, which are both TextBoxes. The same issue is also happening for SBUClientDropdown but I believe the resolution will be similar:

DBHandler DBHandler = new DBHandler();
List<string> clients = new List<string>();
List<string> clientGroups = new List<string>();
