• ExtJS RowEditor on Grid

  - by Ian Warner

  Hi When my users edits the Grid via RowEditor combo entries and checkboxes are annoying 1 Apple 2 Orange 3 Pear For instance with the combo above the user will select Orange then update - the Grid now instead of saying orange will display the number 2 - I would like it to show orange when a successful edit has been made. code for my combo editor : { allowBlank : false, displayField : 'team', editable : false, emptyText : 'Select Team', forceSelection : true, lazyRender : true, mode : 'remote', name : 'team', store : storeTeam, triggerAction : 'all', valueField : 'id', xtype : 'combo' } I think I read that you could send the complete row back to insert or I should listen to the update of the grid and then change the field but I need some guidance on what is best Cheers

• Proper usage (best practices) of Browsable attribute in .NET for runtime grid component behavior

  - by Dan

  I understand how Browsable attribute is supposed to work. It's supposed to hide a property from showing up in a PropertyGrid in design time. It also has another effect in that it will stop a Property from showing up in components such as Grids, or specifically Infragistics WinGrid. I am not sure if it has this behaviour on regular Windows Forms grids. This works, but it doesn't sound like Browsable is being use as intended when being used for 'Run time' displaying of a property on a grid component. Any literature from Microsoft on proper use. Even though it works, I don't want to use this attribute to hide columns on a grid bound to a business object if it's not indeed the correct usage of the attribute, but rather something some grid vendors decided to use to determine property visibility on their grids.

• jQuery image grid effect

  - by anon

  I have an image sitting on a page that I want to create a grid type overlay (that covers the image with a black fill) which will be partitioned into 50x50 pixels (what ever size, tbh) squares. The squares on the grid will then flip over, one at a time, in random positions revealing the image below it. The only way I can think of accomplishing this would be to create a whole bunch of grid squares and overlay them on the image with jQuery, then flip each image square individually. This, though, would be a pain in the ass. Doing this all dynamically in jQuery is what I'm hoping to accomplish. Any ideas?

• Javascript Grid that can handle sections in a table

  - by user335410

  I am making an ASP.NET MVC application that lets a user design a questionnaire that other users can fill out. Now, questionnaires, rather than just having a list of questions, often have sections or subsections that could have headings and not the other columns that an ordinary row (a question) would have. I want a JS Grid that can handle sections and subsections elegantly. I tried using JQGrid, but there the options I have are limited to a "Grid as Subgrid" structure. The appearance becomes quite complex and unlike a questionnaire. Is there a Javascript Grid or a JQuery plugin that can handle this? I can write my own HTML table as long as the JS app will format the table and will add some user-friendliness to the table.

• Wanting a type of grid for a pixel editor

  - by wiggles

  Hi, I am currently trying to develop a basic pixel editor application to build up my programming experience with Java. I am designing it so the user has several colour options on, they click on an option and then they can drag over the cells in the grid and they change colour (like a typical image editor, but with a sort of snap on to each grid cell) Any idea of what Java component, if any, is able to implement this type of grid in Java? I had thought of each cell being a JButton, but this seemed terribly inefficient and I don't think it would be possible to change the colour of each cell(button) with out individually clicking on each one. Any help appreciated.

• Optimizing a fluid grid layout

  - by user1815176

  I recently just added a grid layout, but I can't figure out how to make my links work. The grid that I used is the 1140 one at http://cssgrid.net/. I studied the source code of that website, and tried to make my page like theirs, but when I put everything in it made mine worse, and the grid didn't even work. This is how my website is supposed to look http://spencedesign.netau.net/singaporehome.html and this is how it does http://spencedesign.netau.net/home.html And when you reduce the size, it doesn't look like it's supposed to. When you minimize it I want the pictures(links) to be two per row, then one per row depending on how small the page is. I also want the quote to turn into different rows when it is too small for it. But I can't figure out how to make the page look normal regularly let alone make it look good with a smaller browser. Thanks!

• Grid computing projects similar to NGrid (thread based)

  - by DivdeAndConquer

  Hello there, first time poster. This is a great place for reading about programming problems. I've been looking at some grid computing projects for .Net/Mono and stumbled upon NGrid. NGrid seems really appealing for grid computing because you simply pass threads to it and there is very little modification you have to make to your code. However, I see that NGrid (http://ngrid.sourceforge.net/?page=overview) is still at version 0.7 and hasn't been updated since May 2008. So, I'm wondering if there are any other grid computing projects that use a similar thread-passing architecture and if anyone has had success using NGrid.

• 2D Tile Collision free movement

  - by andrepcg

  I'm coding a 3D game for a project using OpenGL and I'm trying to do tile collision on a surface. The surface plane is split into a grid of 64x64 pixels and I can simply check if the (x,y) tile is empty or not. Besides having a grid for collision, there's still free movement inside a tile. For each entity, in the end of the update function I simply increase the position by the velocity: pos.x += v.x; pos.y += v.y; I already have a collision grid created but my collide function is not great, i'm not sure how to handle it. I can check if the collision occurs but the way I handle is terrible. int leftTile = repelBox.x / grid->cellSize; int topTile = repelBox.y / grid->cellSize; int rightTile = (repelBox.x + repelBox.w) / grid->cellSize; int bottomTile = (repelBox.y + repelBox.h) / grid->cellSize; for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { if (grid->getCell(x, y) == BLOCKED){ Rect colBox = grid->getCellRectXY(x, y); Rect xAxis = Rect(pos.x - 20 / 2.0f, pos.y - 20 / 4.0f, 20, 10); Rect yAxis = Rect(pos.x - 20 / 4.0f, pos.y - 20 / 2.0f, 10, 20); if (colBox.Intersects(xAxis)) v.x *= -1; if (colBox.Intersects(yAxis)) v.y *= -1; } } } If instead of reversing the direction I set it to false then when the entity tries to get away from the wall it's still intersecting the tile and gets stuck on that position. EDIT: I've worked with Flashpunk and it has a great function for movement and collision called moveBy. Are there any simplified implementations out there so I can check them out?

• How can I make the Telerik progress bar work?

  - by Darien Fawkes

  I have a Telerik progress bar in my project: <telerik:RadProgressManager ID="RadProgressManager" Runat="server" /> <telerik:RadProgressArea ID="RadProgressArea" Runat="server"></telerik:RadProgressArea> <asp:button id="Button1" runat="server" text="Submit" /> On button click I try to run this method: private void MethodWhichUpdatesTheProgressContext(UploadedFile file, int countFile) { const int total = 100; RadProgressContext ProgressContex = RadProgressContext.Current; ProgressContex.SecondaryTotal = "100"; for (int i = 0; i < total; i++) { ProgressContex.CurrentOperationText = "Uploading zip file percentage " + i.ToString(); if (!Response.IsClientConnected) { break; } System.Threading.Thread.Sleep(100); } } Project builds without any errors but progress doesn't change. How do I properly fire the progress bar animation? If I put this progress bar on control, it can effect this?

• Magento Set Grid to Filter Automatically by Current Day using Existing Datetime Column in Grid

  - by Tegan Snyder

  In Magento I'm creating a custom module and would love to be able to filter automatically by the datetime column so that the intial grid listing shows only entities related to "todays" date. Here is my datetime column: $this->addColumn('ts', array( 'header' => $hlp->__('Activated'), 'align' => 'left', 'index' => 'ts', 'type' => 'datetime', 'width' => '160px', )); I'm think there should be a way for me to just add a filter to the collection like so: $now = Mage::getModel('core/date')->timestamp(time()); $dateTime = date('m/d/y h:i:s', $now); $collection = Mage::getModel('mymodule/items')->getCollection() ->addFieldToFilter('ts', $dateTime); But this doesn't work? Am I using the wrong filter? My "ts" field in the database is a "datetime" field, but the default magento "From: " - "To:" date range selectors don't use hours, minutes, seconds. Any ideas? Thanks, Tegan

• ItemsPanel vs Grid vs GridSplitter

  - by bitbonk

  I am currently trying to build a ControlTemplate for an ItemsControl that uses the Grid as its ItemsPanel where each item is stacked horizontally and delimited with a GridSplitter. The basic goal is to have a dynamic bindable ItemsControl where all items stack up in a row and where each item can be resized with a splitter. There are two things I can't wrap my head around: How is the GridSplitter supposed to end up automatically between each item? How do I set Grid.Column for each item.

• Sorting and Paging a Grid of Data in ASP.NET MVC

  This article is the fifth installment in an ongoing series on displaying a grid of data in an ASP.NET MVC application. Previous articles in this series examined how to sort, page, and filter a grid of data, but none have looked at combining one or more of these features in a single grid. This article and the next one show how to merge these features into a single grid. In particular, this article looks at displaying a grid that can handle both sorting and paging. The subsequent article will examine combining sorting, paging and filtering. Like with its predecessors, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more! Read More >
