• TreeView update bug in the VB.NET

  - by CFP

  Consider the following code: Dim Working As Boolean = False Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterCheck If Working Then Exit Sub Working = True e.Node.Checked = Not e.Node.Checked Working = False End Sub Private Sub TreeView1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseClick If e.Button = Windows.Forms.MouseButtons.Right Then MsgBox("Checked = " & TreeView1.SelectedNode.Checked) End Sub Where TreeView1 is a TreeView added to the form, with CheckBoxes set to true and one node added. The code basically cancel any node checking occuring on the form. Single-clicking the top node to check it works well : your click is immediately canceled. Yet if you double-click the checkbox, it will display a tick. But verifying the check state through a right click will yield a Checked = False dialog. How come? Is it a bug (I'm using the latest .Net Framework 4.0, and he same occurs in 2.0), or am I doing something wrong here? Is there a work around? Thanks! EDIT: Additionally, the MouseDoubleClick event is not raised before you click once again. EDIT 2: Posted a bug report at Microsoft Connect

• XSLT for-each loop for element collection

  - by brain_pusher

  Is it possible to make a for-each loop in XSLT not for a node set, but for my own collection of elements? For example, I split some string and have a string collection as a result. And I need to create a node for each item in the collection. I know that issue can be solved with a recursive template, but I want to know if it is possible to avoid a recursion.

• Strange behaviour of DataTable with DataGridView

  - by Paul

  Please explain me what is happening. I have created a WinForms .NET application which has DataGridView on a form and should update database when DataGridView inline editing is used. Form has SqlDataAdapter _da with four SqlCommands bound to it. DataGridView is bound directly to DataTable _names. Such a CellValueChanged handler: private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { _da.Update(_names); } does not update database state although _names DataTable is updated. All the rows of _names have RowState == DataRowState.Unchanged Ok, I modified the handler: private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { DataRow row = _names.Rows[e.RowIndex]; row.BeginEdit(); row.EndEdit(); _da.Update(_names); } this variant really writes modified cell to database, but when I attempt to insert new row into grid, I get an error about an absence of row with index e.RowIndex So, I decided to improve the handler further: private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { if (_names.Rows.Count<e.RowIndex) { DataRow row = _names.Rows[e.RowIndex]; row.BeginEdit(); row.EndEdit(); } else { DataRow row = _names.NewRow(); row["NameText"] = dataGridView1["NameText", e.RowIndex].Value; _names.Rows.Add(row); } _da.Update(_names); } Now the really strange things happen when I insert new row to grid: the grid remains what it was until _names.Rows.Add(row); After this line THREE rows are inserted into table - two rows with the same value and one with Null value. The slightly modified code: DataRow row = _names.NewRow(); row["NameText"] = "--------------" _names.Rows.Add(row); inserts three rows with three different values: one as entered into the grid, the second with "--------------" value and third - with Null value. I really got stuck in guessing what is happening.

  Consider two QuerySet objects of the same class. Is there a simple way to unify them into a single QuerySet, similar to addition but without duplicates. Also, is there a simple way to subtract them? Removing all elements that appear in both sets from one of the sets?

• ASP.Net Custom Paging (w/ C#)

  - by André Alçada Padez

  Cenario: I have a GridView bound to a DataSource, every column is sortable. my main query is something like: select a, b, c, d, e, f from table order by somedate desc i added a filter form where i can define values to each one of the fields and get the results of a where form. As a result from this, i had to do a custom sorting so that when i sort by a field, i am sorting the filtered query and not the main one. Now i have to do custom paging, for the same reason, but i don't understand the philosophy of it: I want to guarantee that i can: filter the results sort by a column when i click on page 2, i get page two of the filtered and sorted results I don't know what i have to do, so i can bind the GV with this. My sorting Method, that is working just fine looks something like: string condition = GetConditions(); //gets a string like " where a>1 and b>2" depending on the filter the user defines string query = "select a, b, c, d, e, f from table "; string direction = (e.SortDirection == SortDirection.Ascending)? "asc": "desc"; string order = " order by " + e.SortExpression + " " + direction; UtilizadoresDataSource.SelectCommand = query + condition + order; i've never done custom paging, i am trying: GetConditions() //no problem here How can i find out how the GridView is sorted (by what field and sortingorder)? thank you very much

• Display the value of a select list without a button

  - by Max Zeygelshefer

  How can I get the value to be displayed after the selection from the list is made, without the use of a button. I tried to implement an onChange event for the select list, and doing away with the button, but I can't get it to work. I'd like the value (1,2,3) to display below the select box after an option (a,b,c) is selected. <script> function displayResult() { this.nextSibling.nodeValue = document.getElementById("mySelect").value; } </script> <body> <form> <select id="mySelect" style="width:220px"> <option value="1">a</option> <option value="2">b</option> <option value="3">c</option> </select> </form> <button type="button" onclick="displayResult.call(this)">List Locations</button>

• How would I go about letting a user add and associate a comma separated list of categories while add

  - by Throlkim

  I've been struggling for quite a while to get this feature working: I want my user to be able to select categories when uploading a photograph, but additionally be able to specify a comma-separated list of categories to create/find and associate with the photograph. I've had this working by using an attr_accessor :new_categories on the photographs model, but having that there without the column existing breaks both Paperclip and Exifr. Obviously, image upload and EXIF data retrieval are pretty important for a photography website, but not being able to add categories while uploading a photograph is a pain in the arse. Methods I've tried so far: Using attr_accessor to add a field for new_categories. Breaks gems. Using an Ajax sub-form to add categories. Formtastic can't handle it. Adding a column for new_categories to the photograph model. It works, but it's horrific. I haven't tried using a nested form, but I'd need to intercept it and stop it from processing it as normal. Here's an example of what I'm trying to accomplish: http://imgur.com/rD0PC.png And the function I use to associate the categories: def process_new_categories unless self.new_categories.nil? for title in self.new_categories.split(",") self.categories << Category.find_or_create_by_title(title.strip.capitalize) end end end Has anyone got any ideas as to how to do this?

• Are NHibernate lists loaded on demand?

  - by André Pena

  This is a pretty simple question. When I do this: session.CreateCriteria(typeof(Product)).List(); The resulting list will load as I access it? Let's say, from 100 to 100 elements for example? Or will it load all once? In the case it's not "virtual" how can I make it so? What's the best pratice about it? Thanks;

• How do I make JavaScript to set these element values?

  - by dmanexe

  I have two fields that need to multiply each other and fill a 3rd form's value. Here's the HTML: <input type="text" name="estimate[concrete][price]" value="" onBlur="calc_concreteprice(document.forms.mainform);" /> per SF <strong>times</strong> <input type="text" name="estimate[concrete][sqft]" value="" onBlur="calc_concreteprice(document.forms.mainform);" /> SF = <input type="text" name="estimate[concrete][quick_total]" value="" /> Here's my JavaScript: function calc_concreteprice(mainform) { var oprice; var ototal; oprice = ((mainform.estimate[concrete][sqft].value) * (mainform.estimate[concrete][price].value)); ototal = (oprice); mainform.estimate[concrete][quick_total].value = ototal; } I want the first two forms to be multiplied together and output to the third. I think my problem may be within how I am referencing the input field names, with brackets (I'm taking results from this form as an array so I'm already used to working with the results as a multi-dimensional array). Thanks for the help!

• How can I find the dimensions of a matrix in Python?

  - by PBD10017

  How can I find the dimensions of a matrix in Python. Len(A) returns only one variable. Edit: Hi Thanks. close = dataobj.get_data(timestamps, symbols, closefield) Is (I assume) generating a matrix of integers (less likely strings). I need to find the size of that matrix, so I can run some tests without having to iterate through all of the elements. As far as the data type goes, I assume it's an array of arrays (or list of lists).

• MVC3 html.TextBox

  - by BigTommy79

  I have login view that takes a LoginPageViewModel: public class LoginPageViewModel : PageViewModel { public string ReturnUrl { get; set; } public bool PreviousLoginFailed { get; set; } public LoginFormViewModel EditForm { get; set; } } which is rendered in the view. When a user tries to log in I only want to post the LoginFormViewModel (Model.EditForm) to the controller: public ActionResult Login(LoginFormViewModel loginDetails) { //do stuff } Using Html.TextBox I can specify the name of the form field manually 'loginDetails.UserName' and post back to the controller and everything works. @model Web.Controllers.User.ViewModels.LoginPageViewModel @using (Html.BeginForm()){ @Html.Hidden("loginDetails.ReturnUrl", Model.ReturnUrl) @Html.LabelFor(x => x.EditForm.UserName, "User Name:") @Html.TextBox("loginDetails.UserName", Model.EditForm.UserName) @Html.ValidationMessageFor(x => x.EditForm.UserName) ..... But what I want to do is to use the staticaly typed helper, something like: @Html.TextBoxFor(x => x.EditForm.UserName) But I'm unable to get this to work. Are you only able to post back the same model when useing the strongly typed helpers? Is there something I'm missing on this? Intellisense doesn't seem to give any clues such as a form field string.

• [VB.Net] TreeView update bug in the .net framework

• What is the appropriate granularity in building a ViewModel?

  - by JasCav

  I am working on a new project, and, after seeing some of the difficulties of previous projects that didn't provide enough separation of view from their models (specifically using MVC - the models and views began to bleed into each other a bit), I wanted to use MVVM. I understand the basic concept, and I'm excited to start using it. However, one thing that escapes me a bit - what data should be contained in the ViewModel? For example, if I am creating a ViewModel that will encompass two pieces of data so they can be edited in a form, do I capture it like this: public PersonAddressViewModel { public Person Person { get; set; } public Address Address { get; set; } } or like this: public PersonAddressViewModel { public string FirstName { get; set; } public string LastName { get; set; } public string StreetName { get; set; } // ...etc } To me, the first feels more correct for what we're attempting to do. If we were doing more fine grain forms (maybe all we were capturing was FirstName, LastName, and StreetAddress) then it might make more sense to go down to that level. But, I feel like the first is correct since we're capturing ALL Person data in the form and ALL Address data. It seems like it doesn't make sense (and a lot of extra work) to split things apart like that. Appreciate any insight.
