  • Streaming content from (sharepoint) web part

    - by Mikko Rantanen
    How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end. This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

  • Getting values from the html to the controller

    - by tina
    Hi, I'm trying to access the values a user introduces in a table from my controller. This table is NOT part of the model, and the view source code is something like: <table id="tableSeriales" summary="Seriales" class="servicesT" cellspacing="0" style="width: 100%"> <tr> <td class="servHd">Seriales</td> </tr> <tr id="t0"> <td class="servBodL"> <input id="0" type="text" value="1234" onkeypress = "return handleKeyPress(event, this.id);"/> <input id="1" type="text" value="578" onkeypress = "return handleKeyPress(event, this.id);"/> . . . </td> </tr> </table> How can I get those values (1234, 578) from the controller? Receiving a formcollection doesn't work since it does not get the table... Thank you.

  • Error when passing quotes to webservice by AJAX

    - by Radu
    I'm passing data using .ajax and here are my data and contentType attributes: data: '{ "UserInput" : "' + $('#txtInput').val() + '","Options" : { "Foo1":' + bar1 + ', "Foo2":' + Bar2 + ', "Flags":"' + flags + '", "Immunity":' + immunity + '}}', contentType: 'application/json; charset=utf-8', Server side my code looks like this: <WebMethod()> _ Public Shared Function ParseData(ByVal UserInput As String, ByVal Options As Options) As String The userinput is obvious but the Options structure is like the following: Public Structure Options Dim Foo1 As Boolean Dim Foo2 As Boolean Dim Flags As String Dim Immunity As Integer End Structure Everything works fine when $('#txtInput') contains no double-quotes but if they are present I get an error (for an input of asd"): {"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected. (22): { \"UserInput\" : \"asd\"\",\"Options\" : { \"Foo1\":false, \"Foo2\":false, \"Flags\":\"\", \"Immunity\":0}}","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"} Any idea how I can avoid this error? Also, when I pass the same input with quotes directly it works fine.

  • Finding controls inside nested master pages

    - by evanmortland
    I have a master page which is nested 2 levels. It has a master page, and that master page has a master page. When I stick controls in a ContentPlaceHolder with the name "bcr" - I have to find the controls like so: Label lblName =(Label)Master.Master.FindControl("bcr").FindControl("bcr").FindControl("Conditional1").FindControl("ctl03").FindControl("lblName"); Am I totally lost? Or is this how it needs to be done? I am about to work with a MultiView, which is inside of a conditional content control. So if I want to change the view I have to get a reference to that control right? Getting that reference is going to be even nastier! Is there a better way? Thanks

  • Using application roles with DataReader

    - by Shahar
    I have an application that should use an application role from the database. I'm trying to make this work with queries that are actually run using Subsonic (2). To do this, I created my own DataProvider, which inherits from Subsonic's SqlDataProvider. It overrides the CreateConnection function, and calls sp_appsetrole to set the application role after the connection is created. This part works fine, and I'm able to get data using the application role. The problem comes when I try to unset the application role. I couldn't find any place in the code where my provider is called after the query is done, so I tried to add my own, by changing SubSonic code. The problem is that Subsonic uses a data reader. It loads data from the data reader, and then closes it. If I unset the application role before the data reader is closed, I get an error saying: There is already an open DataReader associated with this Command which must be closed first. If I unset the application role after the data reader is closed, I get an error saying ExecuteNonQuery requires an open and available Connection. The connection's current state is closed. I can't seem to find a way to close the data reader without closing the connection.

  • Reusing datasource

    - by nubby
    I'm tying to use one database call and reuse that data for other controls - without having to do another call. Scenario: I call the books table which returns all the authors and titles. I create an author's list control called list1 to displays all the titles by Shakespeare and a list2 to display titles by Charles Dickens. Void Bindme() { string commandText = "Select * from books"; SqlCommand mycommand = new SqlCommand(commandText, datasource1); datasource1.Open(); SqlDataReader myReader1 = mycommand.ExecuteReader(); list1.DataSource = myReader1; list1.DataBind(); list2.DataSource = myReader1; list2.DataBind(); datasource1.Close(); } In my example only the first bind to the source, list1, gets data. Any ideas?

  • Compiling code at runtime, loading into current appdomain.

    - by Richard Friend
    Hi Im compiling some code at runtime then loading the assembly into the current appdomain, however when i then try to do Type.GetType it cant find the type... Here is how i compile the code... public static Assembly CompileCode(string code) { Microsoft.CSharp.CSharpCodeProvider provider = new CSharpCodeProvider(); ICodeCompiler compiler = provider.CreateCompiler(); CompilerParameters compilerparams = new CompilerParameters(); compilerparams.GenerateExecutable = false; compilerparams.GenerateInMemory = false; foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies()) { try { string location = assembly.Location; if (!String.IsNullOrEmpty(location)) { compilerparams.ReferencedAssemblies.Add(location); } } catch (NotSupportedException) { // this happens for dynamic assemblies, so just ignore it. } } CompilerResults results = compiler.CompileAssemblyFromSource(compilerparams, code); if (results.Errors.HasErrors) { StringBuilder errors = new StringBuilder("Compiler Errors :\r\n"); foreach (CompilerError error in results.Errors) { errors.AppendFormat("Line {0},{1}\t: {2}\n", error.Line, error.Column, error.ErrorText); } throw new Exception(errors.ToString()); } else { AppDomain.CurrentDomain.Load(results.CompiledAssembly.GetName()); return results.CompiledAssembly; } } This bit fails after getting the type from the compiled assembly just fine, it does not seem to be able to find it using Type.GetType.... Assembly assem = RuntimeCodeCompiler.CompileCode(code); string typeName = String.Format("Peverel.AppFramework.Web.GenCode.ObjectDataSourceProxy_{0}", safeTypeName); Type t = assem.GetType(typeName); //This works just fine.. Type doesntWork = Type.GetType(t.AssemblyQualifiedName); Type doesntWork2 = Type.GetType(t.Name); ....

  • Gridview rowcommand after refreshing

    - by xt_20
    I have a gridview inside an updatepanel. After updating the gridview, accessing the individual rows does not seem to give the right row. For example: protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) { GridViewRow row = ((e.CommandSource as Control).NamingContainer as GridViewRow); Row from the above code gives the values from the gridview before the gridview is refreshed/updated. Anyone knows how to get the updated values?

  • ASP.NET MVC Actions that return different views, or just make a ton of Actions?

    - by Nate Bross
    So, I am in a situation, where I need to display a different view based on the "Role" that the authenticated user has. I'm wondering which approach is best here: [Authorize(Roles="Admin")] public ActionResult AdminList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } [Authorize(Roles = "Consultant")] public ActionResult ConsultantList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } or should I do something like this [Authorize] public ActionResult List(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); if(HttpContenxt.User.IsInRole("Admin") { return View("AdminList", data ); } if(HttpContenxt.User.IsInRole("Consultant") { return View("ConsultantList", data ); } return View("NotFound"); }

  • Unit Testing and SharePoint Development

    - by MagicAndi
    Hi, I am interested in writing unit tests for the SharePoint development work I am doing. Can anyone suggest practical approachs to implementing unit tests in MOSS? Note that any third party tools have to be free (but not necessarily open-source); the company I work for will not pay for additional tooling. In particular, any alternatives to the Typemock Isolator for SharePoint would be appreciated. Thanks, MagicAndi.
