I have a master page that loops through form keys looking for a specific key:
[Code]....
Problem, if I use an UpdatePanel on a page when this code is hit the last form key is null. If I don't use an update panel, all is good. Why does the UpdatePanel send a null form key in the list?
I am attempting to call a RESTful service using an HttpWebRequest object via POST. I am attempting to pass 1 variable with the Request body which contains a url encoded string. I see the request when it hits the server; however, it shows 2 form variables. The first is Form[null] and the second is my variable.I am attempting to locate the source of this NULL key; however, I cannot. Any ideas on how I may be able to remedy this since it's throwing issues when I attempt to use it with the Nancy web framework for .Net.
Code:
var request = WebRequest.Create("http://localhost:8888/RouteName") as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";[code]...
I have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.
Just to test, I created a blank website and a blank web site project.
When I added a referece to web site by doing right click and add reference it added the dll inside a BIN folder but on ther other hand when I did the same for a web site project it created a reference folder for me and then added the dll under the reference folder.
I am going to outline my setup then where i am failing
UpdatePanel1 - Contents : 3 textboxes and AddButton
UpdatePanel2 - Contents : 1 GridView and SubmitButton
AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page

I developed a web site more then a year ago with .net2.0/c#/mssql 2005. it works fine but i was asked to replace mssql with mysql.
I wrote a class to complete data access works (unfortunately, I didnt use nhibernate or other data access tools :((
I edited the class to use System.Data.Odbc objects rather than System.Data.SqlClient.
It works fine in selecting data but not manipulating data. when i try to insert new data it adds null data for all fields in the table.
in debug mode, i noticed that it might be caused by OdbcParameter but not sure.
I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

I'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

I have a InsertCommand function i am using to insert the dropdownlist in my updatepanel. When the Add button is clicked. It adds the record multiple times. Am not sure why it does this. Here is my code.
Dim Bank_number
As
DropDownList = UpdatePanel1.FindControl("ddlbank")Dim
NoteAccountNumber As
DropDownList = UpdatePanel1.FindControl("ddlAccount")'
UpdatePanel1.ChangeMode(FormViewMode.Insert)
lblsee.Visible =
"true"
'now collect selected information on the drop down
RelationshipTest.InsertParameters(
RelationshipTest.InsertParameters(
"bank_number").DefaultValue
= ddlBank.SelectedValue.ToString"noteaccountnumber").DefaultValue
= ddlAccount.SelectedValue.ToString'Insert into db
RelationshipTest.Insert()
Also, i was woundering if any of you might know the logic behind clearing inserted data from the dropdownlist once its inserted. I am trying to make sure data is not entered mulitiple times. Unique Indexing comes to mind but thats only on the backend.
I am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.
How to implement updatepanel functionality without updatepanel?
I am tring to use XMLHttpRequest but I am getting problem while redering a usercontrol containing postback controls in response of an Ajax request.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
I am sending the resluts of my form via a function that calls a HTML template that inserts the values. I would like to include a if statement that checks to see if a form field is NULL and then inserts a "n/a" to place in the HTML template.
Here is the function that sends the form:
[Code]....
So in the above code the value of fname=john and the value of lname is blank, I want to anything that is blank with "n/a"
I have a simple ASP.Net page, and I am enumerating through the controls doing things to the controls via reflection (localising the page - but that is whole other can of managerial dictat type worms). So...I have a test page thus:
<%@ Page Title="" Language="C#" MasterPageFile="~/Master Pages/Root.master" AutoEventWireup="true" CodeFile="refelectiontest.aspx.cs" Inherits="refelectiontest" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Button ID="Button1" runat="server" Text="Button" />
[Code]....
Now, if I just run this, it barfs with an object null exception. And if I step through the code, putting a breakpoint on the control.ID line, then indeed the ID is null. However, if I then expand the control object, the ID fills itself out and all is well.
It looks like the ID is only getting completed at the last moment - how can I ensure that I can get the ID without getting null? The same thing happens if I don't use the master page.
I have a Global.cs within my App_Code.
Here is the variable I have set:
static string _conString;
//Connection String
public static string conString
{
get { return _conString; }
set { _conString = ConfigurationManager.ConnectionStrings["BreakersConnectionString"].ToString(); }
}
When I use Global.conString in my web form code behind it comes up as null.
I am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here
I'm at a loss, this is the first time I have seen these problems occur.
I have a form and stored procedure that inserts the data from the form. It works fine except that if a field isn't filled in it doesn't insert a NULL into sql it inserts "".
I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction.
Here is the required part of the code, if you require more just let me know.
[code]....
So if I enter nothing into address1 field it should write NULL to screen but it always writes NOT NULL.
So I have a page to edit employees.
Here is my view model:
[code]....
I'm not sure why this is happening. The dropdown is loaded correctly when I navigate to the page, but not when the view is redisplayed.
i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.
I have a few updatepanel in my asp.net webform . I'm doing some tests and I'm wondering how can i check what data send back to server in different situations ?
