Why am I getting this error? I'm trying to do a calculation on my GridView2 and I'm using clientside javascript. I need to add the onkeyup attribute. How do I do this?
Code Behind:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
CType(GridView2.FindControl("TextBox13"), TextBox).Attributes.Add("onkeyup", "calculateSubTotal")
End Sub
I have a page with a number of user controls, In one of my user controls I have a button event. I turn on output cache for the user control that has the button and vary by control using the ID property of a hidden field control in the user control. whenever I turn on the output cache my button event doesn't fire.
View 2 RepliesI am trying to send data from text fields created on the client side (via jquery). The problem is the data from those text boxes is not being post back ( I'm using asp.net webforms)
I have used fiddler to view the post back data and it isn't there for those generated text fields.
I'm surprised no one figured it out. I was switching from server to non server controls I forgot to give the non ones a name field..........
// Add answer field
$('#addAnswer').click(function ()
{
count++;
var html = '<p>' +
'<input id="answer' + count + '" type="text" maxlength="255" runat="server" />' +
'<a id="removeAnswer" class="removeIcon" href="#"><img class="removeIcon" src="/Content/images/minus.gif" /></a>' +
'</p>'
$(html).appendTo('#answers');
return false;
});
Here is part of my code. The commented portion is the logic in which i am trying to implement. I want client side validation to be done and checked to see if it is correct format (MM/DD/YYYY).

View 2 Repliestime for some expertise. I have a datalist which contains a radiobutton in the itemtemplate. This radiobutton is disabled (set enabled to false) by default. On the html output I have a checkbox, which, when ticked, enables the radiobuttons through javascript. This is all working fine. The rb's are enabled and I can check them. However when the page is posted back. The checked property is always false.
I use the code below to retrieve the value of this rb:
[Code]....
This code is working fine when the initial state of the radiobuttons set to enabled server side.
I am using ASP.NET 3.5.
When the user click on say btnSubmit I want to first execute some JavaScript code and then execute some C#/VB.NET code.
Is this possible? If so how would one do it?
Anyway, if for example I have a textbox that I want to enable when the user check the desired checkbox/radiobutton, I like the textbox to be default enabled=false. What's the good approach between these two?
a.) client side
[Code]....
I need to know on the serverside, if a RadioButton has been disabled (by javascript) on the clientside.
The (serverside) Enabled property is not the same as the (clientside) disabled property. Using MyRadioButton.Attributes("disabled") doesn't do the trick either.
I'm curious, anyone know the mechanism a checkbox control uses to remember that its checked or not checked after a postback?If I add them manually to a page via html as in <input type="checkbox"/> I have to use javascript and hiddenfields to keep things checked after a postback and I would have to have an onclick="dosomething()" inside the tags.Viewing the html source code for a page with a .NET checkbox control, there is nothing like that there.
I was writing a custom control and rendered my own checkboxes when I came across this problem. After the postback, the control would reload the checkboxes from viewstate and forget the user had clicked anything. As I couldn't use hiddenfields to track the changes (they got reset from viewstate too), I ended up using .NET checkboxes as childcontrols instead but this experience got me thinking.
How can I get ClientSide(JavaScript) Value for My ASP.net Custom Control?
for example I want to get a value like this:
var selectedItemID = getElementById("<%=MyControl1.ClientId%>").value;
How can i set a specific Value in my control scripts to get it from ".value" property like above?
Additional Note:
i want ".value" property(javascript) to get the dropDown control(one of my controls in my custom control) selected Value.
i want to show the Require filed validators first.then i want to validate the page controls. how to achieve this.
i wrote onclientclick event like this.
but i want to show required filed validators first .
I know the built-in ASP.Net validators come with a client-side framework, however I've been unable to find anything that lets me check a single validator for it's Valid state.
The validator in question is a RegularExpressionValidator, which I use to determine whether an e-mail address is valid or not.
Here's some brief code:

Can any one provide me an idea about any ajax control which has following capabilities:
User should able to type to get auto-suggestions Dropdown should only display the values starting with the keyed-in characters. Most importantly there should be only one postback to fetch all the data to client side on the first key-in and then should filter the list values based on rest of the keys.
i have a complete form in my database as row for example name of the field ,is mandatory, sortid, regularexpression, datatype, maxlength , default value etc. So the form is completely dynamic.now i want to perform the client side validation on the form . What will be the best practice for doing that? like i have to see that if the field is mandatory check it for null and if not then leave it on the client side . i am thinking about setting hidden field for it .
View 2 RepliesI have a razor view in ASP.NET MVC3 application.This view has 2 partialviews PartialView1 is strongly typed and binded with the model.PartialView2 is not binded with the model.and this view consists of a collection of checkboxes.As part of validation atleast one checkbox must be checked to continue with the save.
Following is the jquery code that is giving me error:
Object does not support this property or method.
Error occuring at this line of code:
$("#form0").validate({ rules: { issueCheckBox: { selectNone: true}} });
Following is the JQuery code:
<script src="../../Scripts/jquery-1.4.4.min.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.validate.unobtrusive.min.js"

We store the location information in a table. Numbers of records are over four thousand. This table structure is self-recursive. In our web project, we use dropdownlist control to populate all these locations. We got performance slow problem. So googling about Caching, we consider to use Data Caching with Sql Dependency. However, not found yet a full-covered sample in .NET 2.0 and SQL Server 2005 or 2008.
View 1 RepliesMy web application is using the asp.net cache object to store data from the database. I am looking for an elegant to invalidate cache objects but haven't come up with anything elegant yet. It is easy to invalidate a single record or a list of all records in a single table, by keeping track of their cache keys. However I may have any number of lists of subsets of a table's data. I would like to invalidate only the cache records of the lists that contain a particular record, when that record changes. I don't want to have to invalidate all the lists of data for that table if only one of the lists contain that record.
View 1 Repliessubject says it all...... when using the various validation controls like requiredFieldValidator, and EnableClientScript is true (the default), does that mean that the only validation is done client side? or does it mean that it is done client side in addition to server side?
I know if the only validation is done client side, like with javascript, it can easily be circumvented. I want to make sure my validation is done serverside, so do I need to set EnableClientScript to false?
I'm currently using Validation controls to validate a form. I tried adding a separate onclientclick javascript method to do some extra validation but it now appears to only run this and not continue on to run through the Validation controls. The extra javascript method is returning true, so I'm not sure if the onclientclick is clobbering the scripts from the Validation controls. Can anyone explain what I've done wrong?
View 4 RepliesI have a required validator that I check a textbox clientside, but then on post I check the database for values that have been used. I want to show the error in the RequiredFieldValidator when it post back. How do I do this?
View 1 RepliesI have used ajaxtool kit's autocomplete on a page which gets data from a webservice. This autocomplete is slow, at the time I only have 10 to 20 records in table and it take about 3 to 5 seconds to search and show result in autocomplete. User have to wait about 4 second on average to see data.
View 1 RepliesI have a reporting page with a gridview and a calendar. When the user loads the page, the default date is today and when he clicks on a date in the calendar control, it loads the reporting data for that day. Each user has a different report and the data is between 300-500 rows per day. At the moment, I have a linq query that returns the data for a day in the form of a list. Given the relatively small amount of data per query, I'd like to store the result of the query in the session so that I can do the paging and sorting from the session, without going back to the data store.
What I'm looking to do is a list of lists so that when the query loads, the data is saved until the session times out. For instance, if the user selects 4-5 different dates, each of these queries is saved in the session and then if he clicks on one of those dates again, a function first checks to see if the data is in the session: GetQueryFromSession( DateTime TheDate). I'm stuck on this. How do you create a list of lists that works with the session object.
What's the best way to cache web site user data in asp.net 4.0? I have a table of user settings that track all kinds of user or session specific stuff like the state of UI elements (open/closed), preferences, whether some dialog has been dismissed, and so on. Since these don't change very often (for each user, anyway) but are looked up frequently it seems sensible to cache them. What's the best way? These are the options I've identified...
Store them in HttpContext.Current.Session directly (e.g. Session["setting_name"]) Store them in HttpContext.Current.Cache Use a global static dictionary, e.g. static ConcurrentDictionary<string,string> where the key is a unique userID + setting name value Store a dictionary object for each session in Session or Cache What's the most sensible way to do this? How does Session differ from Cache from a practical standpoint? Would it ever make sense to store a dictionary as a single session/cache object versus just adding lots of values directly? I would think lookups might be faster, but updates would be slower since I'd have to re-store the entire dictionary when it changed.
What problems or benefits might there be to using a global static cache? Seems like this would be the fastest, but I'd have to manage the size. I could just flush it periodically if it hits a certain size, or keep a cross reference queue and remove things oldest first when it gets to a certain size. Does this make any sense or is it just trying too hard?
