Somehow my onclientClick is not returning the value false correctly. I am trying to prevent the user from clicking on the button. How ever user can click on it first time in this case. I am looking to turn off my LinkButton's Click event, by setting it to false. How would I do this? Somehow returning false doesn't cancel the event.

I am working in an ASP.NET MVC Application. I have a view model as follows:
[code]....
From UI Perspective user can enter date as mmddyyyy. And when user enters in such format 01012001, my ModelState.IsValid code piece in controller returns false. When I did a quick watch in ModelState, I see an error for the propery "SampleDate", saying "The Value 01012001 is not valid for SampleDate".
In my modelbinder, during the OnModelUpdated event I tried to format the value 01012001 to 01/01/2001 and assigned it back to SampleInterestViewModel.SampleDate thinking that ModelState.IsValid might return true without that error. But still ModelState.IsValid is false and I when I looked in to the ModelState dictionary, this particular property still has that errors in its collection.
Lastly I tried to format 01012001 and update the value 01/01/2001 directly to the Property SampleDate in the ModelState dictionary. But still ModelState.IsValid is false showing the same error for the SampleDate property. Can't figure out why ModelState.IsValid works and how and when it gets set to false.
If the User enter 01012001 in the UI, I still need to format it in the modelbinder to 01/01/2001 and make sure that ModelState.IsValid it true so that the rest of my controller code can work as expected. In the UI I am doing an AjaxSubmit to post the sampleDate value.
I just want to add some client side (JQuery Javascript) validation in a web user control. I put an OnClientClick handler and the function gets called. BUT, even if I return "false", the OnClick method always get fired. What am I doing wrong ?
I'm with VS 2010, targeting the 4.0 framework with JQuery 1.4.2. and JQuery UI 1.8.4.
Here's a sample code :
<td style="text-align:right"><asp:Button ID="btnAddSave" OnClientClick="return ValidateMail();" OnClick="btnAddSave_Click" runat="server" Text="Submit" /></td>[code]...
If I put a breakpoint in the Page_Load event, I see that I get in and the btnAddSave_Click event is also executed.
I am trying to delete an asp.net user from all tables. When I call: bool isDeleted = Membership.DeleteUser(username, true); isDeleted is being set to false; Is there a way to tell why it is not deleting the user?
View 4 RepliesMy ASP.NET app is using windows authentication. If I run the following code:
WindowsIdentity wi = (WindowsIdentity)User.Identity;
foreach (IdentityReference r in wi.Groups)
{
ListBox1.Items.Add(r.Translate (typeof (NTAccount)).Value);
}
if (User.IsInRole ("Everyone"))
Label1.Text = "Is in role";
The listbox will contain the name of every group the user belongs to. If I then call User.IsInRole, and pass in the name of any of those groups, I always get a false.
Model is coming up as Invalid Scenario is I have a custom ViewModel and certain fields don't show up on the screen (like Id & some computed fields etc..) so when the data gets posted back the Model.IsValid() comes to false Q Do I have to pre init these fields when I do create
ActionResult CreateOrder(int customerID)
{
var order=new OrderViewModel();
//shall I init the fields which are not being keyed in by the user?
}
In our code, we have to give the users a list of printers to choose from. The user then chooses a printer and it is checked to verify it is valid before printing. On a windows 2003 server with IIS 6, this works fine. On a windows 2008 server with IIS 7, it fails each time impersonate is set to true.
PrinterSettings printerSetting = new PrinterSettings();
printerSetting.PrinterName = ddlPrinterName.SelectedItem.Text;
if (!printerSetting.IsValid)
{
lblMsg.Text = "Server Printer is not valid.";
}
else
{
lblMsg.Text = "Success";
}
Each time this code is run, the "Server Printer is not valid" displays, only if impersonate is set to true. If impersonate is set to false, the success message is displayed. The impersonation user has full rights to the printer. Is there a way to catch the actual reason the printer is not valid? Is there some other 2008 setting I should check? update I found that IsValid fails when the IIS7 application pools has "Enable 32-bit applications" is checked. This must be checked b/c we are using a 3rd party tool to print with, and it is a 32-bit application. It is not currently part of this test, so right now it is not causing this error.

View 6 RepliesI have a problem with getting jquery to retrieve results from a WCF service. I am hosting the WCF service within IIS and when I attach the debugger to this process I can see that the code is processed successfully. However, when it hits the callback within jquery there is no data??
I have set up a trace on the wcf service and there are no errors. It just seems as though the data is lost after the wcf service method completes.
Here is the jquery code which calls the service:
$.get("http://ecopssvc:6970/ecopsService.svc/Echo", {echoThis: "please work"}, function(data) {
alert("Data Loaded: " + data);
});
Here is the wcf config:
<system.serviceModel>
<services>
<service name="EcopsWebServices.EcopsService" behaviorConfiguration="EcopsServiceBehaviours">
<endpoint address="" behaviorConfiguration="WebBehaviour"
binding="webHttpBinding" bindingConfiguration="" contract="EcopsWebServices.IEcopsServiceContract" />
</service>

<behavior name="EcopsServiceBehaviours">
<serviceMetadata httpGetEnabled="true" httpGetUrl=""/>
<serviceDebug includeExceptionDetailInFaults="true"/>

</system.serviceModel>
Here is the service contract:
[ServiceContract]
public interface IEcopsServiceContract
{
[WebGet]
[OperationContract]
string Echo(string echoThis);
}
Here is the Service implementation:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class EcopsService : IEcopsServiceContract
{
#region IEcopsServiceContract Members
public string Echo(string echoThis)
{
return string.Format("You sent this '{0}'.", echoThis);

In my web form I have a search box. The user enters a string, and once the search button is clicked, I pass the value from my .js file to my .cs file and do some processing to get the results. Up to this point everything is fine, but now I dont know how to get my results back to my .js page. The serach results at this point are in a dataset, and also in an multidimensional array. I have a multi array because I need to pass back the code and description of the items found.

At this point I have used the passed string 'value' to get my required code/descriptions, but i'm not sure how/if I can get either the Dataset or multidimensional array back to my .js page
I have jquery using ajax/json to grab an elements ID and then hits:
[System.Web.Services.WebMethod]
public static string EditPage(string nodeID)
{
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection(Global.conString))
using (SqlCommand cmd = new SqlCommand("contentPageGetDetail", con))
{
cmd.Parameters.Add("@ID", SqlDbType.UniqueIdentifier).Value = Global.SafeSqlLiteral(nodeID, 1);
cmd.CommandType = CommandType.StoredProcedure;
cmd.ExecuteNonQuery();
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
{
da.Fill(dt);
}
}
if (dt.Count > 0)
{
string pageTitle = dt.Rows[0]["Title"].toString();
string contentID = dt.Rows[0]["ContentID"].toString();
return pageTitle, contentID, nodeID;
}
else
{
return "Failed";
}
}
When it's time to return I want to grab all content returned from the stored procedure back to the jquery method in the success section and set a hiddenfield, dropdown value, and a title in a textfield. In the jQuery I tried using "pageTitle" but it came up undefined. What do I need to do jQuery side to grab whats being returned and populate fields in my Web Form before showing the form?
This is probably something simple. The following JQuery call is executing and calling the controller. The controller is executing correctly. I used the sample data that's commented out to verify that the templates were working also. However, the success function is not executing in the browser. Any thoughts or other ways I can debug this?
<script type="text/javascript">$(document).ready( function(){ alert("Here"); @* var myData = [ {first: "Jane", last: "Doe"}, {first: "John", last: "Doe"} ]; *@ $.getJSON( "/User/Filter",function(myData){ $("#myDataTemplate").tmpl(myData).appendTo("#itemContainer"); } ); alert("there"); }
);</script>
//Controller
public ActionResult Filter() { var myData = this.repository.GetAllUsers(); //return Json(myData); return Json(myData, JsonRequestBehavior.AllowGet);}
I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.
There are several issues:
1) The autocomplete function is not firing
2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception
3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return.
4) I am not at all certain that this code will accept JSON data that comes back from the service

I have a LinkButton that I need to perform a click on to cause a postback. The actual link target is:
javascript:__doPostBack('ctl00$c1$btnRefreshGrid','');
Clicking the link does perform the postback, as verified by a breakpoint in the code-behind. Also pasting javascript:__doPostBack('ctl00$c1$btnRefreshGrid','') in the address bar of the browser works with the same effect.
I've tried the following with no effect at all:
__doPostBack('ctl00$c1$btnRefreshGrid','');
$('#ctl00$c1$btnRefreshGrid').click();
$('#ctl00$c1$btnRefreshGrid').trigger('click');
eval($('#ctl00$c1$btnRefreshGrid').attr("href"));
I've tried using both <%= btnRefreshGrid.UniqueID %> and <%= btnRefreshGrid.ClientID %> to generate the selector.

<div id='test'>

and the following jquery code to show this div in a dialog
$("#view_test").click(function() {
$("#test").dialog({ show: 'slide', width: 600, title: 'View Check' });

If view_test button was clicked, initializing the dialog, before the form post backs the checkbox ch1.Checked property in .Net is always False. However if you just postback without initializing the dialog it works as expected.
