  • Sorting Custom Objects with Parameter in VB.Net/C#

    - by Jeffrey Kern
    Let's say I have a custom object of Foo Is there anyway I can sort through a list of these objects, like list<of foo>.sort() and also be able to sort this list with a passable parameter. which will influence the sort? list<of foo>.sort(pValue) I'm guessing I'll need to define two separate sorts, but I am not sure. Thanks!

  • ASP.net: Efficient ways to convert DataSets to GenericCollection (Of ObjectType)

    - by jlrolin
    I currently have a function that gets some data from the database and puts it into a dataset. The return type on my function is GenericCollection (Of CustomerDetails) If I do this: Dim dataset As DataSet = Read(strSQL.ToString) 'Gets Data from DB What's the most efficient way to map the dataset results to an collection of objects. More importantly, since I'm using GenericCollection, is there a way to do this in which I can call a function from the ObjectType class (CustomerDetails) that would have a means to converting that specific object. Or is there a way in which I can use a function that would handle all types? Is there a way to do something like: Return returnedResults.TransformDataSet(dataset) In which returnedResults is an object collection Of CustomerDetails, or would it simply be easier to have TransformDataSet return an object collection Of CustomerDetails by itself? Thanks for any help.

  • ASP.NET Radio Button State and Back Key

    - by Dave S
    When using the browser back key on a page with radio buttons and using auto-postback, the state of the buttons (checked) stays the same while other parts of the page do not. This results in a situation where button two is checked and the cached page (because of server-side logic) displays a message that button 1 is checked. What is the best way to handle this situation? The following code example exhibits this behavior: [Form:] <asp:RadioButton ID="rb1" runat="server" AutoPostBack="true" Text="Button1" OnCheckedChanged="rb_CheckedChanged" GroupName="rbgroup" Checked="true" /> <br /> <asp:RadioButton ID="rb2" runat="server" AutoPostBack="true" Text="Button2" OnCheckedChanged="rb_CheckedChanged" GroupName="rbgroup" /> <br /> <hr /> <asp:Label ID="lbl1" runat="server">Button 1</asp:Label> [Code Behind:] protected void rb_CheckedChanged(object sender, EventArgs e) { if (rb1.Checked == true) lbl1.Text = "Button 1"; else lbl1.Text = "Button 2"; }

  • dynamically build Intersect statement ASP.NET

    - by TDDG
    I would like to use the IEnumerable function Intersect() to combine a few list and get the similar integers from each list. The problem I'm faced with is that I don't know how many list I will need to compare. Here is an example: A{1,2,3,4} B{1,2,3} C{1,2} results = A.Intersect(B).Intersect(C) This works great, but the next time around I may have a D{1,2} next time I come across the function. I'd like to use the Intersect method, but I'm open to new ideas as well.

    - by Lijo
    I have a button named searchReportButton. On this button click, I need to check session value from server using a ajax web method "Error.aspx/CheckSessionExpiry".This is done in checkSession javascript function. The checkSession is not returning anything now - instead it is handling the required operation based on the result (redirecting to error page). I need to return the result of ajax web method to the Main Caller. How can we do this return? Main Caller searchReportButton.click(function () { checkSession(); //Remainging Code }); Helper function checkSession() { var win = 101; $.ajax( { type: "POST", url: "Error.aspx/CheckSessionExpiry", data: '{"winNumber": "' + win + '"}', contentType: "application/json; charset=utf-8", dataType: "json", success: handleSessionResult } ); } Result Helper function handleSessionResult(result) { if (result.hasOwnProperty("d")) { result = result.d } if (result == "ACTIVE") { window.location.href("Error.aspx"); return false; } //alert(result); }

    I'm using Entity Framework for creation of my Data Access Layer and I want for all of my classes to be internal. I know it is possible to manually assign it manually in the designer for each class. But looks like it also requires to set internal modifier for each single property in every class!
