View 1 RepliesI have a radio button list. I want to get its selected item text and value client side suing javascript...
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 several lines of code like this:
[Code]....
How can I do this?
Here is my attempt:
[Code]....
here is (part of, its 50 items long) the radiobuttonlist
[Code]....
and i use the value of the 'Value' attribute to make a selection
[Code]....
then I want the 'text' property of SelectedItem to be in the subject line of an email
[Code]....
but no matter what i do, it uses the 'Text' property of the first item in the list that has the same 'Value' as the one from the selection
I have the following ASP.NET RadioButtonList:
[code]....
I would like to select an item in the list programmatically via a client-side jquery function like this (simplified version):
[code]....
Ideally, there is some function - in the above code I have proposed selectItemByValue - that selects an item in a RadioButtonList by a given value. Does jquery have a similar function built-in? If not, how should I go about implementing the desired functionality?
I am using simple radiobuttonlist with four items, I have enabled viewstate and postback but whatever option I choose it always return first value.
Here is the code:
<asp:RadioButtonList runat="server" AutoPostBack="true"
EnableViewState="true" OnSelectedIndexChanged="Changed" ID="rbSlots">
</asp:RadioButtonList>
ListItem item = new ListItem(starthour + " - " + stophour + ds.Tables[0].Rows[i]["LastName"].ToString(), ds.Tables[0].Rows[i]["xavid"] + "¤" + ds.Tables[0].Rows[i]["xuserid"]);
and I have RadCalendar, on which SelectedDateChanged Event I populate the radlist
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.
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...

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?

I have stumbled upon the issue when I need to retract html controls I've added client-side using JavaScript after the postback (due to server-side validation - this is not optional). I'm trying to achieve this is cr*p and there's a better way of doing this.
basically, what I'm doing is cloning a textbox control for up to 10 times on the page when the user hits "Add" and storing entered values from each of those texboxes in a hidden field to read from in the code behind. This works fine, however, when the server side validation doesn't pass after postback, all those dynamically added (cloned) texboxes disappear, since ViewState knows nothing about them.
I am considering 2 possible solution, both of which seem hacky:Rebuild all cloned textboxes on document onload() using stored values in the hidden field wrap the form in ajax update panel and place the cloned texboxes outside of it, thus, not refreshing this part of the screen on postback now, is it possible to somehow "update" ViewState to make it aware of all the html controls I've added using client-side script? I'd like to achieve this with client-side script, therefore not considering cloning textboxes on server-side,

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?
View 1 RepliesIs there any way to add a confirmation dialog to a submit button when the form already has other validation controls and a summary control using "showmessagebox=true"? I tried adding
OnClientClick="return confirm('Are you sure?');" to the submit button, but that seems to block all of the other validation?
want to know that can we validate a control which is out side a form element in asp.net(server side validation)and outside a form element in html(client side validation) let's take a closer look
<html>
<body>
<input type="text" name="first name"/>
</body>
</html>
can we apply clien side validation on above text box by java script ?in asp.net
<form runat="server">
</form>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
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.
