I have a Repeater and also a Button. If I click on my button a new rows need to be created to the repeater in client side (javascript). I am able to do this with server side, but want to avoid a postback. I am not using an Ajax Updatepanel control. Moreover I am using a table structure in my Repeater.
View 1 RepliesI have a repeater which contains a table. I am giving the user the ability to add a new row in the repeater by adding a new row to the table. As I am very new to jQuery, can someone give sample code?
View 1 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 appologise if thisis a silly question but i just want to be completely sure something is not possile before i tell this to my manager.
i am a WinForms programmer by trade, but i have put in charge of making a web site for our sales team, and web development is a new area for me. the web site is written in ASP.NET, C# code. it is finished, however they are complaining that there are too many page refreshes.
first of all, we have an SQL server with all our data in it. on the main web page, the user must select their country of interest from a DropDownList. when they do this, all our customers from that country are displayed in an html table, generated by a Repeater. i have set AutoPostBack on the country DropDownList to true, so each time the user selects a different country, the SelectedIndexChanged event handler is called, and in here i generate a new sql statement with the selected country, and re-bind the Repeater.
There are also a few other DropDownLists that do other 'filtering' stuff. for example, one DropDownList selects whether to display customers whose license expires soon (within a week), and another DropDownList filters the customers who currently have an open support case. All the DropDownLists have their AutoPostBack set to true, and in their SelectedIndexChanged event handler, i work out the sql based on the values of the DropDownLists, and re-bind the Repeater.
the problem with the above is that each time the user selects a different value from the DropDownList, the page refreshes, clearly because the AutoPostBack is set to true for them all. so to stop this i need to set AutoPostBack to false - but then of course the SelectedIndexChanged event handlers are not called, and so i have no place to rebind the repeater with my new sql statement.
so what i really need, is to be able to set a DropDownList's AutoPostBack to false, and handle the rebinding of the Repeater in some client-side event, which does NOT result in a postback. the Repeater will be bound by some sql, which is generated by the values in the DropDownLists (eg "SELECT * FROM custTable WHERE [Country]='" + CountryDropDownList.Text + "'"), so in this client-side event i need to be able to reference the asp.net controls.
I have a gridview with a template field of check boxes.I have my rows color coded in BLUE color in the gridview based on a database value on page load.Now I want a button on the page to loop through the gridview and select the the checkbox for the rows that are in BLUE Color without a post back.
View 1 RepliesI have a table that the user can add rows to through javascript by clicking on a "add rows button". In each row there are two columns one with a dropdown list and the other a text box. The dropdown list is populated with data through a sub on server side code.I need to be able to insert the data from each row into a table but I'm unable to do this. I clicked on my "add rows button" to add several rows and then did a test to see how many rows the table was returning on the server side and it did not include the five rows I added .. only the header row.If there is a better way to allow users to dynamically add rows to a table and then access the dynamically created table on the server then I'm all ears!
View 3 RepliesI am trying to find a way in whihc I CAN Move the columns of nested repeaters from one to another. Like I have three caegories of products say A,B,C and I will have X,Y,Z products within each categories and I am trying to find a way of I can find a way that on client side the user can drag items from one category to another like the drag functionality of Ajax control kit ReOrder List.
View 1 RepliesI have a repeater that has a LinkButton in the Item Template. The LinkButton displays a UserControl that consists of a FormView. The UserControl has an HTML Element that when clicked hides the UserControl by simply change the display of the control from 'block' to 'none'. If the 'Close' span is clicked, the UserControl is successfully hidden, but afterward, the 'Edit' linkbuttons no longer postback.
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");
[code]...
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 have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?

View 4 RepliesI am trying to set a hidden type value to x on Server Side and then access it with Javascript. I have tried multiple ways to accomplish this.
At the basic level this is what I am trying to do.

HidRowNumber.Value = EFileRowNumber.Text;
Javscript
var status = document.getElementById("<%= HidRowNumber.ClientID %>").value;
When I am debugin it say it HidRowNumber's Value has changed to x but when I access the value with JS it always returns ''.

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?
View 1 RepliesI 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...
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.
