Client Side Javascript Call From Control Doesn't Reset Visibility?
Jan 3, 2010
I have a javascript to enable text boxes when called, I want to trigger this code when a user picks value "Custom" from a dropdownlist, so that I can display/Hide these new textboxes.
function setVisibility(DropDownListID) {
var element = document.getElementById(DropDownListID);
var element1 = document.getElementById("TestBox1");
if (element.value == "Custom") {
element1.visible = !element1.visible ;
}
<asp:DropDownList ID="DateRangeDropDownList" runat="server" Enabled="True" onChange="setVisibility('DateRangeDropDownList');">
<asp:ListItem>Some Value</asp:ListItem>
<asp:ListItem>Custom</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TestBox1" runat="server"></asp:TextBox>
For some reason it doesn't seem to work.

I 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 an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.

I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I
insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):
[code]...
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)

Maybe I've picked a totally inappropriate/bad example. What I have is a user control that contains a bunch of dynamically created Telerik RadGrids. My user control is added to a couple of Telerik RadPageViews that are part of a RadMultiPage that is used alongside a RadTabStrip. What I need to do is call a Javascript function in my usercontrol to update it's display whenever it's parent RadPageView is selected.
So basically I have the following Javascript code:
function OnClientTabSelected(sender, args)
{
// Get the MyControl that is on this tab
var myControl = $find("whatever");
// Call a method that updates the display
myControl.doSomething();
}

I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?

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...

Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.

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 have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding.
I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions.
But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config.
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
ResponseFormat = WebMessageFormat.Json,
RequestFormat= WebMessageFormat.Json) ]
How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?
Or put another way, this may be incorrectly worded, can an endpoint have multiple bindings?

Using MicrosoftMvcValidation.js, it seems like disabled html elements are validated on the client-side. I am not sure how much sense that makes given that such elements will not be submitted by the form and I probably consider it a bug. (By the way, MicrosoftMvcJQueryValidation.js does not validate disabled elements.)
Is there any way I can disable (pun intended) the validation of disabled elements? E.g., assuming I have a reference to an html element in javascript, is there some way I can "remove" it or disable it from the client-side validation machinery?

I have a gridview and I have to control the visiblitiy of the grid columns using javascript. Consider this gridview. I have a few columns.
<asp:GridView ID="grdTest" runat="server" AutoGenerateColumns="False" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkResource" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Resource">
<ItemTemplate>
<asp:Label ID="Resource" Text='<%# Bind("Resource") %>' runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Description" HeaderText="Resource Description" HtmlEncode="false">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
</asp:TemplateField>
</Columns>
</asp:GridView>
I can control the visibility of these columns at the server side by using this -
grdTest.Columns[n].Visible = false;
But, I have to control the visibility from the client side using javascript. I tried a lot but I was only able to access either the row object or any particular cell of the gridview.
grid.rows[index].cells[i].style="display: none"; //for cell
Is there a way to access the column object of the gridview and control its visibility using javascript?
