Hi All,
I am creating a custom server control.That control contains a check box list. For the first time I am getting value for that check box list, at run time through Get/Set property. In Property I am using View state for setting value. While page is post back, the view state is getting null. How can I preserve the value of view state. Sample code is as follows,

{string strItems;
string[] StrArrItem = null;char cSplitChar = ',';
int intLegth = 0;_chkList = new CheckBoxList(...

Why I get old values from a textbox even if they are changed?
Hi to all,i'm developing a dnn component that updates some data stored on the db. To do so, i've made a simple select query to fetch the old values, then the onload event popolates a form using a VB codebehind.To update the user changed data, i've insert a update_button, that the user must click in order to run the update.in the codebehind, i've made a function raised on the update_button.click event but when the update function collects the changed data, it still collects the old values, even if they are changed... WHY? could someone help me?please :) Thanks to all,/D
Have you put an "If Not Page.IsPostBack Then" statement around your onload code? Failure to do this would cause you to pick up the same values each time. Hope this helps Please mark posts as the answer if I was helpful. Thanks!Visit my blog
Yep! Was That... i forgot that because... i'm novel in .net developing... Now works fine! really really thanks! ...

where is the value saved of the form controls(such as textbox) in post backs?
hello!
I have some puzzle in view state.I have just read an article in Msdn about view state.http://msdn2.microsoft.com/en-us/library/ms972976.aspx,It says, there are many stages in the life cycle of the page,and the Stage 2 is Load View State,the Stage 3 is Load Postback Data.In Stage 2 ,it says : During this stage, the view state data that had been saved from the previous page visit is loaded and recursively populated into the control hierarchy of the Page. And the Stage 3 is Load Postback data of the form controls,
My first question is: what is the difference of the view state data(Stag 2)and the value of the control(Postback data in Stag 3).
And the article of Msdn also says :It is a common misconception among developers that view state is somehow responsible for having TextBoxes, CheckBoxes, DropDownLists, and other Web controls remember their values across postback. This is not the case, as the values are identified via posted back form field values, and assigned in the LoadPostData() method for those controls that implement IPostBackDataHandler.
My second question is :now that the view state is not responsible for the values of the form controls,where is the value save?
thank you.
The values from form inputs such as textboxes etc are captured in the Request.Form collection, or Request.Querystring if you are using GET as opposed to POST. In classic ASP, PHP etc, you have to manually retrieve values from the inputs on postback (form submission) and re...

PayPal Integration with .net (to get values back from PayPal)
We want to integrate our ASP.Net webapplicaiton to PayPal. Currently we are in teh process of developing the application so we are using PayPal sandbox. When user clicks on checkout button we pass the control to paypal sandbox, where the items along with their price is displayed. Now suppose user pays for the items, now control should come back to the main application along with the information whether payment was successful or not and also the transaction id (which we need to put in our database). Please let me know how we can do this. Also, do we need a public ip so that sandbox can send the control back to the main application. Currently the application is under development so not deplyed on any servers with external ips.
Paypal's SDK kit for ASP.Net may be a good start. There are instructions, documentation and sample code available on that site. iHaathiThis post is given AS-IS. No Warranties.
Check Rick's article http://www.west-wind.com/presentations/PayPalIntegration/PayPalIntegration.asp
ThanksMark post(s) as "Answer" that helped youElectronic ScrewWebsite||Blog||Dub@i.net

Get values set by javascript to .net enabled textbox

Getting viewstate value from readonly textbox in .NET2 (VB)
Hey guys...I have a form that asks for several dates. I tried using asp calendar controls to set values of the date textboxes which were readonly. I found this annoying since each time I advanced a month and/or selected any date, it posted back and refreshed the page. So, instead, I resorted to an old javascript function I use a lot. The javascript creates a pop up (html) window and sets the value of the textbox when the user picks a date. I had done this many times in ASP.NET1. However, since upgrading to .NET2, I noticed I was getting errors and the data I was...

How to change the value of textbox without posting page back to the server
Hello everyone,
I have a simple form with 3 textboxes namely txtNumber1, txtNumber2, txtTotal.
The txtTotal will display the sum of txtNumber1 and txtNumber2. I'd like when the user enter a number either in txtNumber1 or txtNumber2 the txtTotal will automatically update its value without posting page back to the server. Do I need to utilize Ajax to accomplish it?
Thanks for reading.
There are couple of options you can use:
1] Use Java Script to Populate your txtTotal on change of text in txtNumber1 / txtNumber2
2] You can use AJAX, by putting your controls in UpdatePanel. Have a button Calculate (outside Update Panel), which will calculate and populate txtTotal from you.
Ho[pe this helps.
Thanks,
-Nirmal
I think i will use the first approach. But could you please tell me more detail?I'm not sure how to use JavaScript in ASP.NET pages.

How to retain and get the selected value of the drop down upon post back
Hi
I have a form view. Inside the formview I have a drop down. I did not bind the drop down with the ODS. Instead I do it manually on the code behind. If the user selects a value I display a textbox beside the drop down and allow the user to enter the value. Upon onblur event of the textbox I do a postback and in the page load i check whethere the page has been posted. If so I add this value to the datatable and once again bind it to the combo box and set the selected value to the text box value.
If the user clicks the save button and when I look for the selected value it says Nothing.
What could be the problem. Please help me in this regard.
Thanks a lot in advance.
SelectedValue could be found on the same page. If there is a postback, it will be gone. Could you show your code?
Please post your code so we can further assist you, but it seems that the value isn't being passed.~~ Believe in Science, not religion. Science will always progress, religions will always collapse. ~~
Try to user below code: <asp:dropdownlist Id="1" Runat="Server" SelectedValue='<% Eval("Some data")%' DataTextField="Some Data Column" Sqldatasource="Sqldatasource1" />I guess this will help you.Here Selected value attribute will help you show the selected value of the user and datatext will help you show the dropdown data.....it may or may in your datasource don...
I need a multiline textbox that preserves word wrap on post back
Hi,
I need a control that can satisfy the following:

2. Must be able to specify maximum line length (35 characters) and maximum number of lines (4).
3. When posted back, I need access to each line of text as it looked on the clients page, so it can be stored in 4 different database fields that each have a maximum length of 35 characters.
This is all in order to spare users the hassle of entering their four permitted lines of text in 4 separate ...
