Let me explain the case;On the asp.net page, i have a repeater which generates <tr>s and <td>s.On clientside, i have a js function which adds or deletes rows into that repeater-generated-table.The problem is, in this function, i dont only generate a simple row, a textbox (which i have to get its value on server side) is generated too. Is there any way to get value of client-generated controls ?
View 3 RepliesThe idea is that a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button). These rows contain textboxes, dropdownlists, checkboxes and other input controls. When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on server side, validate it and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows. put me in the right direction?? Or someone offering a better solution to the problem?
i have a grid as
<asp:GridView ID="dgv_passengerdetails" runat="server" AutoGenerateColumns="False"
CssClass="pasdetailsgrid" BorderStyle="None">
<Columns>
<asp:BoundField HeaderText="Seat No" DataField="seatno">
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
[code]...
the string gs=null, if i click the button again then gs takes the value from textbox.
I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
What is the best way to show the server-side generated HTML (full page) into a new popup window? It should be triggered upon clicking a button (causing a postback to the server).
Edited:
The HTML content are dynamically generated in the code behind and the content is full page (<html> ... </html>). Upon clicking a button on the web page, I would like to get the generated html content and pass it to the browser and show it in a new popup window. The content will be the final result (UI) not HTML tags.
I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).
This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?
I've got a function I wrote quite some time ago that works fine, but I'd like to speed up the process and lessen server load by doing the same job in Javascript.I seem to be able to GET textbox values ok, but I can't seem to SET textbox values (I'm'-a JS noob). Can anyone lend a hand in converting my VB.NET code to it's JS equivalent?

View 1 RepliesI am using a dropdown, a devexpress grid view and a button on my page.
My gropdown contains the months in the format MM/YYYY, and on dropdown's selection change the data binds in the grid view.
the functionality of button is to go on previous page as same as back button of browser.
Now, my prob is that if i select any month and then select another month, the data changes.
but now when i click on back button having onclick ="history.go(-1)", changes the data on the grid view but the month in the dropdown remains the same.
For example:
Suppose, first i have month selected as 02/2010. At this time the data in grid view is for exapmle 01234
now when i select month 03/2010 the data in grid changes to 56789
now when i click on back button, then data in grid changes to 01234 but the month in dropdown remains to 03/2010.
I want to get the values from the Invisible rows from my gridview. here is my code.
<asp:GridView ID="gvTeam" runat="server" Width="900px"
AutoGenerateColumns="False" BackColor="White" BorderColor="#CC9966"
BorderStyle="None" BorderWidth="1px" CellPadding="4">

What is the best library/software to compress the dynamically generated javascript on server? I use javascriptzip to do so statically. Any solution for .Net platform? P.S. compression involves removing unnecessary spaces + language compression like changing new Object() into { }
View 2 RepliesI have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
View 1 RepliesI have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

can we apply clien side validation on above text box by java script ?in asp.net

but I am rather confused about what to invest in. I heard that server-side code translates into client-side code. So, if you have an .aspx file, it will be converted to HTML/CSS/JavaScript. I have experience with the latter three technologies put into a rather dull text file and rendered by a web browser. My question is how much HTML/CSS/Javascript coding would I have to do when server-side programming? In other words, can someone using ASP.NET program purely on the server side and not bother to write for the client side? Of course, I don't care about server-side being translated into client-side, but I am wondering if client-side programming needs to be done explicitly and to what degree.
