  • how to get the value of a kendoui dropdown list selected value in a listview

    - by user1568738
    am having Some kendoui listviews which consists of kendoui dropdown lists and i want to get those dropdown list selected values. To do this am trying, $("#cnty1").val(); and here is my dropdownlist,i.e., list of countries coming from Database table, <input select STYLE="width:90px;height:auto" id ="cnty1" data-bind="value:cnty1" name="cnty1" data-type="string" data-text-field="cnty" data-value-field="cntyid" data-source="sourcedata1" class="k-d" data-role="dropdownlist" /> <span data-for="cnty1" class="k-invalid-msg"></span> here cnty1 is the id of the dropdown list, but am not getting the value instead am getting "id" of the slected value but not the selected value. And also if the value is not selected am getting the first value id by using $("#cnty1").val(); So, please suggest me a solution so that, 1) I should get only the Selected value and 2) Value of the dropdown list Only if the user selects a value from the list, but don't get the value of the list without selecting.

  • Canny edge detection - grayscale images always coming up as 3-channel, unusable?

    - by cvcentral
    I am working through the book "Learning OpenCV" from the O'Reilly series and am trying to perform a canny edge detection sample. Any grayscale image I choose seems to come up as having 3 channels, and to the best of my knowledge, canny only works with single channel images, so this always fails. I am even using the images provided by OpenCV. Here is my code.. IplImage* doCanny(IplImage* in, double lowThresh, double highThresh, double aperture) { if(in->nChannels != 1) return(0); //canny only handles gray scale images IplImage* out = cvCreateImage(cvSize(in->width, in->height), IPL_DEPTH_8U, 1); cvCanny(in, out, lowThresh, highThresh, aperture); return(out); }; IplImage* img = cvLoadImage("someGrayscaleImage.jpg"); IplImage* out = doCanny(img, 10, 100, 3); Why might this always give me 3-channel images? How can I solve this?

  • In ExtJS, how do I place two fieldsets side-by-side in a panel with a hbox layout?

    - by Daniel T.
    In ExtJS, I'm having a little trouble placing two fieldsets side-by-side in a panel with a hbox layout. The hbox layout seems to be unaware of the fieldset's height, and cuts it off, even if I explicitly set the panel's height to something large. Here's what it looks like: The blue border is the hbox panel, and there's 2 fieldsets inside, 'Client Info' and 'Owner Info'. The code is like so (simplified and runnable in Firebug): var clientInfo = { xtype: 'fieldset', defaultType: 'textfield', title: 'Client Info', items: [ { fieldLabel: 'First Name' }, { fieldLabel: 'Last Name' }, { fieldLabel: 'Cell Phone #' }, { fieldLabel: 'Work Phone #' } ] }; var ownerInfo = { xtype: 'fieldset', defaultType: 'textfield', title: 'Owner Info', items: [ { fieldLabel: 'First Name' }, { fieldLabel: 'Last Name' }, { fieldLabel: 'Cell Phone #' }, { fieldLabel: 'Work Phone #' } ] }; new Ext.Panel({ layout: 'hbox', frame: true, height: 400, width: 800, defaults: { flex: 1 }, items: [ clientInfo, ownerInfo ] }).render(document.body); P.S. If you remove defaults: { flex: 1 }, the fieldsets render correctly, but doesn't automatically resize to fit the container, which is something I need. Does anybody know how to fix this rendering issue? Thanks.

  • Sub-classing TreeView in WinForms for mouse over tool tips

    - by Matt
    Ok, this is a weird one. The expected behaviour for a TreeView control is that, if ShowNodeToolTips is set to false, then, when a label for a tree node exceeds the width of the control (or, more accurately, it's right hand edge is past the right hand edge of the client area), then a tooltip is shown above the node showing the full item's text. I'd like to disable that, because the above semantic doesn't always work, depending on what the treeview is contained within. So I have rolled my own, and got the tooltips to work (and line up better than the default one!) - but I would like to be able to disable the 'default' behaviour for situations where it would work natively. So, can anyone point me in the right direction as to which message to post to the TreeView in order to disable that behaviour? I have looked at the windows control reference, but couldn't find anything that looked like it might be the one.

  • Declaring data types in SQLite

    - by dan04
    I'm familiar with how type affinity works in SQLite: You can declare column types as anything you want, and all that matters is whether the type name contains "INT", "CHAR", "FLOA", etc. But is there a commonly-used convention on what type names to use? For example, if you have an integer column, is it better to distinguish between TINYINT, SMALLINT, MEDIUMINT, and BIGINT, or just declare everything as INTEGER? So far, I've been using the following: INTEGER REAL CHAR(n) -- for strings with a known fixed with VARCHAR(n) -- for strings with a known maximum width TEXT -- for all other strings BLOB BOOLEAN DATE -- string in "YYYY-MM-DD" format TIME -- string in "HH:MM:SS" format TIMESTAMP -- string in "YYYY-MM-DD HH:MM:SS" format (Note that the last three are contrary to the type affinity.)

  • Reverse-engineer a Javascript object?

    - by TruMan1
    I have a Javascript object that I want to pass in more parameters, but the documentation is non-existant. My only option seems to be to reverse engineer the Javascript object to see what parameters and values I can pass in. For example, I want to see if there is a "zoom" parameter for the object and what values I can pass into the "mapType" parameter: <script type="text/javascript" src="http://maps.google.com/maps?oe=utf-8&amp;file=api&amp;v=2&amp;key=your-gmap-key"></script> <script type="text/javascript" src="https://share.findmespot.com/spot-widget/js/SpotMain.js"></script> <script type="text/javascript"> var widget = new Spot.Ui.LiveWidget({ renderTo: "spot-live-widget", feeds: [ "0Wl3diTJcqqvncI6NNsoqJV5ygrFtQfBB" ], height: 400, width: 500, mapType: "physical" }); </script> <div id="spot-live-widget"/> Any ideas on how to do that?

  • input box height issues

    - by Steven Xu
    I'm trying to set an input box with a specific internal height, and I'm running into issues: font-size: 12px; line-height: 12px; height: 12px; display: block; padding: 5px; Is a sample of what I put in inline styles or stylesheets. I would expect the input box value to be visible at full height, but the inner height of the input box ends up being really small, and it always seems to follow the form: actual inner height = css height - 2*border width - 2*padding Funny, because I swear I've done this before without issue. What am I missing?

  • Can a ScatterViewItem dynamically resize to fit its content?

    - by Brett
    We're hosting a control inside of a ScatterViewItem that dynamically changes its size at runtime as a result of having various sub-elements added, removed, and/or collapsed. We would like to have the hosting ScatterViewItem resize as well to properly fit its child controls, but we're having a hard time making this happen. We've tried a number of different things and the closest we've come is hooking into the child control's SizeChanged event and explicitly setting the ScatterViewItem's Width and Height, but this approach still has issues. When you define a ScatterViewItem and its content in XAML, the ScatterViewItem is sized appropriately. We would like to force the same behavior at runtime when its content changes size. Any help would be greatly appreciated. Thanks!

  • How to manipulate the default behaviour of jQuery Imageflow?

    - by Tim
    Some of you sure know the jQuery-Plugin Imageflow on hxxp://finnrudolph.de/ImageFlow/ (sorry for that, I definitely need to gain reputation, working on it ;)) The default behaviour is that the images within the image-container (which has 100% width in this case) will be resized according to the image-container. There's an option to declare the distance between every image and it would be much better, if this value would be encreased and decreased with the window-resize-event. Everything seems to happen in a function called "moveTo" which is unfortunately also responsible for the resizing when moving to another image. I tried it since hours now but I don't come to a solution. Find the source-code here, and the mentioned function "moveTo" on line 554. Thank your very much for any help! Tim

  • WPF: Aligning the base line of a Label and its TextBox

    - by Heinzi
    Let's say I have a simple TextBox next to a Label: <StackPanel> <StackPanel Orientation="Horizontal"> <Label Margin="3">MyLabel</Label> <TextBox Margin="3" Width="100">MyText</TextBox> </StackPanel> ... </StackPanel> This yields the following result: As you can see, the base lines of MyLabel and MyText are not aligned, which looks ugly. Of course, I could start playing around with the margins until they match up, but since this is such a common requirement I'm sure that WPF provides a much easier and more elegant solution, which I just haven't found yet...

  • Hiding flash component scrollbars using object/param syntax

    - by Kieran Benton
    Hi all, I'm not sure if this is possible (complete non-flash developer speaking), but we have a 3rd party component that we want to only show a certain topleft hand portion of. I've tried limiting the size of the HTML object container as: <object type="application/x-shockwave-flash" width="600" height="415" data="<url>"> <param name="movie" value="<url>" /> <param name="wmode" value="transparent" /> <param name="allowscriptaccess" value="always" /> <param name="quality" value="high" /> <param name="flashvars" value="<vars>" /> </object> So limiting it to 600x415, but this causes horizontal and vertical scrollbars as part of the flash component to appear. Is there any standard way to override this behaviour? Thanks.

  • How to set initial window size in Java OpenGL

    - by tommy-susanto
    Hi guys... I just built a Java OpenGL application in Eclipse... and when i was trying to export the application using EclipseP5Exporter, it requires me to initialize the window size (not viewport size, a window may contain several viewports). I already googled some solutions in the net but I can't seem to get anything useful.. I've tried the method : "glutInitWindowSize(int width, int height);" but it seems to work only in C and python openGL. even if i append the glut before the method (glut.glutInitWindowSize()) eclipse doesn't recognize that method.. So if you guys have any suggestions please let me know... Thank you....

  • Why does calling glMatrixMode(GL_PROJECTION) give me EXC_BAD_ACCESS in an iPhone app?

    - by MrDatabase
    I have an iphone app where I call these three functions in appDidFinishLaunching: glMatrixMode(GL_PROJECTION); glOrthof(0, rect.size.width, 0, rect.size.height, -1, 1); glMatrixMode(GL_MODELVIEW); When stepping through with the debugger I get EXC BAD ACCESS when I execute the first line. Any ideas why this is happening? Btw I have another application where I do the same thing and it works fine. So I've tried to duplicate everything in that app (#imports, adding OpenGLES framework, etc) but now I'm just stuck.

  • Give style attributes to sub-elements inside a <style> tag?

    - by Giffyguy
    My <style> for thumbnails currently looks like this: <style type="text/css"> img.TN { width: 100%; margin-bottom: 5.294%; cursor: pointer; } </style> This is annoying, because I have to apply this style to every single thumbnail image individually, when there could be any number of them on the screen at any given time. All of the thumbnails are inside a single <div> that groups them together, and I'd like to apply a single style to the <div> that will push the attributes I need down to all of the the <img> elements nested inside, regardless how many thumbnails there are. I'm using ASP.NET 2.0, and CSS 2.0 Does anyone know how to do this? Thanks!
