• ASP.NET ObjectDataSource, change CommandName property of FromView Button

  - by Tone

  I have an ObjectDataSource that I'm using with a FormView, and it works fine, but i want to change one small thing. On the FormView the button that fires the update has the CommandName attribute set to "Update," but I would like to change that attribute to something other than "Update" - when I do change that attribute the update no longer works. The reason I want to do this is I have multiple FormViews on the same page and need to have multiple update buttons. Below is my code: FormView: <asp:FormView ID="fvGeneralInfo" runat="server" DataSourceID="objInstructorDetails" CssClass="Gridview" OnItemCommand="fvGeneralInfo_ItemCommand" DefaultMode="Edit"> <EditItemTemplate> <table> .... <tr> <td style="text-align:right;"> <asp:Label runat="server" ID="lblGeneralInfoMessage" Text="General Info updated successfully" Visible="false" /> </td> <td> <asp:Button runat="server" ID="btnUpdateGeneralInfo" ValidationGroup="UpdateGeneralInfo" Text="Update" CommandName="Update" /> <asp:Button runat="server" ID="btnCancelGeneralInfo" Text="Cancel" CommandName="CancelGeneralInfo" /> </td> </tr> </table> </EditItemTemplate> </asp:FormView> ObjectDataSource: <asp:ObjectDataSource ID="objInstructorDetails" runat="server" TypeName="AIMLibrary.BLL.Instructor" SelectMethod="GetInstructorDetails" InsertMethod="InsertInstructor" UpdateMethod="UpdateInstructor" OnInserting="objInstructorDetails_OnInserting" OnUpdating="objInstructorDetails_OnUpdating" > <SelectParameters> <asp:QueryStringParameter Name="InstructorId" QueryStringField="InstructorId" /> </SelectParameters> <UpdateParameters> <asp:Parameter Name="instructorId" Type="Int32" /> <asp:Parameter Name="firstName" Type="String" DefaultValue="" /> <asp:Parameter Name="middleName" Type="String" DefaultValue="" /> <asp:Parameter Name="lastName" Type="String" DefaultValue="" /> <asp:Parameter Name="phone" Type="String" DefaultValue="" /> <asp:Parameter Name="email" Type="String" DefaultValue="" /> <asp:Parameter Name="addressLine1" Type="String" DefaultValue="" /> <asp:Parameter Name="addressLine2" Type="String" DefaultValue="" /> <asp:Parameter Name="city" Type="String" DefaultValue="" /> <asp:Parameter Name="state" Type="String" DefaultValue="" /> <asp:Parameter Name="zip" Type="String" DefaultValue="" /> <asp:Parameter Name="abcBoardNumber" Type="String" DefaultValue="" /> </UpdateParameters> </asp:ObjectDataSource>

• How to troubleshoot a Highcharts script that's not rendering data when date is added and hanging the JS engine with large datasets?

  - by ylluminate

  I have a Highchart JS graph that I'm building in Rails (although I don't think Ruby has real bearing on this problem unless it's the Date output format) to which I'm adding the timestamp of each datapoint. Presently the array of floats is rendering fine without timestamps, however when I add the timestamp to the series it fails to rend. What's worse is that when the series has hundreds of entries all sorts of problems arise, not the least of which is the browser entirely hanging and requiring a force quit / kill. I'm using the following to build the array of arrays data series: series1 = readings.map{|row| [(row.date.to_i * 1000), (row.data1.to_f if BigDecimal(row.data1) != BigDecimal("-1000.0"))] } This yields a result like this: series: [{"name":"Data 1","data":[[1326262980000,1.79e-09],[1326262920000,1.29e-09],[1326262860000,1.22e-09],[1326262800000,1.42e-09],[1326262740000,1.29e-09],[1326262680000,1.34e-09],[1326262620000,1.31e-09],[1326262560000,1.51e-09],[1326262500000,1.24e-09],[1326262440000,1.7e-09],[1326262380000,1.24e-09],[1326262320000,1.29e-09],[1326262260000,1.53e-09],[1326262200000,1.23e-09],[1326262140000,1.21e-09]],"color":"blue"}] Yet nothing appears on the graph as noted. Notwithstanding, when I compare the data series in one of their very similar examples here: http://www.highcharts.com/demo/spline-irregular-time It appears that really the data series are formatted identically (except in mine I use the timestamp vs date method). This leads me to think I've got a problem with the timestamp output, but I'm just not able to figure out where / how as I'm converting the date output to an integer multipled by 1000 to convert it to milliseconds as per explained in a similar Railscasts tutorial. I would very much appreciate it if someone could point me in the right direction here as to what I may be doing wrong. What could cause no data to appear on the graph in smaller sized sets (<100 points) and when into the hundreds causes an apparent hang in the javascript engine in this case? Perhaps ultimately the key lies here as this is the entire js that's being generated and not rendering: jQuery(function() { // 1. Define JSON options var options = { chart: {"defaultSeriesType":"spline","renderTo":"chart_name"}, title: {"text":"Title"}, legend: {"layout":"vertical","style":{}}, xAxis: {"title":{"text":"UTC Time"},"type":"datetime"}, yAxis: [{"title":{"text":"Left Title","margin":10}},{"title":{"text":"Right Groups Title"},"opposite":true}], tooltip: {"enabled":true}, credits: {"enabled":false}, plotOptions: {"areaspline":{}}, series: [{"name":"Data 1","data":[[1326262980000,1.79e-08],[1326262920000,1.69e-08],[1326262860000,1.62e-08],[1326262800000,1.42e-08],[1326262740000,1.29e-08],[1326262680000,1.34e-08],[1326262620000,1.31e-08],[1326262560000,1.51e-08],[1326262500000,1.64e-08],[1326262440000,1.7e-08],[1326262380000,1.64e-08],[1326262320000,1.69e-08],[1326262260000,1.53e-08],[1326262200000,1.23e-08],[1326262140000,1.21e-08]],"color":"blue"},{"name":"Data 2","data":[[1326262980000,9.79e-09],[1326262920000,9.78e-09],[1326262860000,9.8e-09],[1326262800000,9.82e-09],[1326262740000,9.88e-09],[1326262680000,9.89e-09],[1326262620000,1.3e-06],[1326262560000,1.32e-06],[1326262500000,1.33e-06],[1326262440000,1.33e-06],[1326262380000,1.34e-06],[1326262320000,1.33e-06],[1326262260000,1.32e-06],[1326262200000,1.32e-06],[1326262140000,1.32e-06]],"color":"red"}], subtitle: {} }; // 2.

• Mix of Arabic and English causes problems in JTextArea (Java)

  - by Dan

  I have a JTextArea which displays HTML of an Arabic web page. So it's essentially a mix of English and Arabic. In the JTextArea, with columns set to 30, certain text just disappears instead of wrapping properly. The weird thing is that if I copy the invisible text and paste it into Notepad, then I can see it in Notepad. If I change the number of columns to 40, everything displays fine. Any ideas?

• An AuthLogic form is giving me incorrect validation errors -- why?

  - by sscirrus

  Hi everyone, I set up AuthLogic for Rails according to the AuthLogic example: http://github.com/binarylogic/authlogic_example. I can log on successfully to the system, but when accessing users/new.html.erb to register a new user, the form returns the following validation errors: Email is too short (minimum is 6 characters) Email should look like an email address. Login is too short (minimum is 3 characters) Login should use only letters, numbers, spaces, and .-_@ please. Password is too short (minimum is 4 characters) Password confirmation is too short (minimum is 4 characters) None of these errors exist in the data I am entering. # new.html.erb <%= form.label :login, nil, :class => "label" %><br /> <%= form.text_field :login, :class => "inputBox", :name => "login", :type => "text" %><br /> <%= form.label :password, form.object.new_record? ? nil : "Change password", :class => "label" %><br /> <%= form.password_field :password, :class => "inputBox", :name => "password", :type => "text" %><br /> <%= form.label "Confirm password", nil, :class => "label" %><br /> <%= form.password_field :password_confirmation, :class => "inputBox", :name => "password_confirmation", :type => "text" %><br /> <%= form.label :email, nil, :class => "label" %><br /> <%= form.text_field :email, :class => "inputBox", :name => "email", :type => "text" %><br /> # Users controller def new @user = User.new render :layout => "forms" end I think the problem is that the data isn't being transferred somehow and therefore AuthLogic doesn't think the inputs are sufficient. Do you have any idea why AuthLogic is telling me the data doesn't satisfy its validation?

• User created Validator wont call Client side validation Javascript on 'complex' user control.

  Hi All, I have created a user control (from System.Web.UI.UserControl), and created my own validator for the user control (from System.Web.UI.WebControls.BaseValidator). Everything works ok until I try to get the user control to do client side validation. While trying to debug this issue I have set 'Control to Validate' to a text box instead of the custom user control, and the client side script works fine! It appears to me that it has an a issue with my composite user control I have created. Has anyone encountered this issue before? Has anyone else seen client side validation fail on custom user controls? Some extra info : The composite control is a drop down list and 'loader image', as it is a ajax enabled drop down list (using ICallbackEventHandler). I know that the client side javascript is being written to the page, and have placed an alert('random message') as the first line in the validator function that only appears if it is validating a text box (i.e. not when it is validating my custom control) Language : C# (ASP.NET 2.0) and jQuery 1.2.6 in aspx file : <rms:UserDDL ID="ddlUserTypes" runat="server" PreLoad="true" /> <rms:DDLValidator ID="userTypesVal" ControlToValidate="ddlUserTypes" ErrorMessage="You have not selected a UserType" runat="server" Text="You have not selected a UserType" Display="Dynamic" EnableClientScript="true" /> in validator code behind protected string ScriptBlock { get { string nl = System.Environment.NewLine; return "<script type=\"text/javascript\">" + nl + " function " + ScriptBlockFunctionName + "(ctrl)" + nl + " {" + nl + " alert('Random message'); " + nl + " var selVal = $('#' + ctrl.controltovalidate).val(); " + nl + " alert(selVal);" + nl + " if (selVal === '-1') return false; " + nl + " return false; " + nl + " }" + nl + "</script>"; } } protected override void OnPreRender(EventArgs e) { if (this.DetermineRenderUplevel() && this.EnableClientScript) { Page.ClientScript.RegisterExpandoAttribute(this.ClientID, "evaluationfunction", this.ScriptBlockFunctionName); Page.ClientScript.RegisterClientScriptBlock(GetType(), this.ScriptBlockKey, this.ScriptBlock); } base.OnPreRender(e); } I know my ControlPropertiesValid() and EvaluateIsValid() work ok. I appreciate any help on this issue. Noel.

• AJAX, Subdomains and the 200 OK response.

  - by b. e. hollenbeck

  A non-hypothetical but abstracted situation: I have a domain www.foo.com, from which I'm making an AJAX POST to beta.foo.com. Examining the XHR object, I see a response header of 200 OK, but no response text - I even get a response 12B long, which is the exact response (a 12-character string) that I'm expecting - but the response text is blank. If this is a cross-domain issue, why am I getting 200 OK, and better yet - why am I seeing the PHP functions fire on the beta.foo.com side - yet getting no response?
