  • How to specify number of headers in section UITableView.

    - by Mr. McPepperNuts
    if ([tempArray containsObject: [sectionInfo indexTitle]]) { return nil; }else { [tempArray addObject: [sectionInfo indexTitle]]; return [sectionInfo indexTitle]; } return [sectionInfo indexTitle]; The code above groups the cells in alphabetical order but displays a blank header instead of the appropriate title. Could this possibly be because I did not specify the number of headers? This would naturally be a single header for every letter in the alphabet.

  • Images inside of UILabel

    - by enby
    hello everyone! I'm trying to find the best way to display images inside of UILabels (in fact, I wouldn't mind switching to something other than UILabel if it supports images with no hassle) The scenario is: I have a table view with hundreds of cells and UILabel being the main component of each cell The text I assign to each cell contains sequences of characters that need to be parsed out and represented as an image In simpler words, imagine a TableView of an instant messenger that parses replaces all ":)", ":(", ":D" etc with corresponding smiley images Any input would be greatly appreciated!

  • How to Validate Pasted Dates in Excel

    - by jimdrang
    I want to validate pasted dates to remove /'s and ensure the year is 4 digits and when users paste them in it overwrites my excel validation. So, If a user pastes 05/19/10 into a cell, I would like it to convert to 05192010 or at least give an error if this is not possible. I don't know enough VB to add sheet-wide code that does this and I'm not sure if it would work when users paste multiple cells at a time.

  • vba Loop over a non-contiguous range

    - by Jeffrey
    I have a non-contiguous range on rows (example address of myRange: $2:$2,$4:$205,$214:$214) and I would like to access a specific row and column within the range. I have tried the following: 'Get the value of the 2nd row, 1st column within the range myRange.rows(2).Cells(, 1).Value However, this is giving me the value of the 2nd row in the WorkSheet, and NOT in the range - meaning it is giving me address $3$1 - and not $4$1 Can someone please explain how I can access the values within in my range? (It may have to do with different areas) Thank You

  • Formatting a CSV File that contains HTML for Import to Excel

    - by Dave
    I would like to export a CSV file from my application for importing into Excel (or any other spreadsheet that supports CSV files). Anyhow, one of the cells in my table have rich content (i.e. HTML) which can, of course, contain commas as well as other HTML characters and formatting. I realize that Excel "can" handle HTML formatted text, but exporting it as CSV tends to screw up the data for importing. Is there some particular way I can format that particular cell so that imports correctly?

  • Editing a table like iPhone Mail

    - by user217572
    The iPhone Mail application has an edit button in the navigation bar. Tapping that button shows a delete button in the toolbar and shows checkbox controls in the table cells. Tapping one or more checkboxes then tapping the delete button causes the checked messages to be deleted. How can I add similar functionality to my own code? Here's a screenshot of the effect I'm looking for:

  • HTML table ignoring element-style width

    - by sangil
    HTML table ignoring element-style width I have an HTML table where certain cells have very long text contents. I want to specify a width (in pixels) for these cells using jQuery, but the rendered table just ignores the given width. Is there any way to force the table to respect this width? Thanks! JSFiddle: http://jsfiddle.net/sangil/6hejy/35/ (If you inspect the cell you can see the the computed width is different than the element-style width) HTML: <div id="tblcont" class="tblcont"> <table id="pivot_table"> <tbody> <tr> <th id="h0" >product</th> <th id="h1" >price</th> <th id="h2" >change</th> </tr> <tr> <!-- this is the cell causing trouble --> <td id="c00" >Acer 2400 aaaaaaaaaaaaaaaaaaaaaaaaaa</td> <td id="c01" >3212</td> <td id="c02" >219</td> </tr> <tr> <td id="c10" >Acer</td> <td id="c11" >3821</td> <td id="c12" >206</td> </tr> </tbody> </table> </div> CSS: .tblcont { overflow: hidden; width: 500px; } table { table-layout: fixed; border-collapse: collapse; overflow-x: scroll; border-spacing:0; width: 100%; } th, td { overflow: hidden; text-overflow: ellipsis; word-wrap: break-word; } th { height: 50px; } ?Javascript: $(document).ready(function() { // THIS LINE HAS NO EFFECT! $('#c00').width(30); });

  • web design PSD to html -> more direct ways?

    - by Assembler
    At work I see one colleague designing a site in Photoshop/Fireworks, I see another taking this data, slicing it up and using Dreamweaver to rebuild the same from scratch. It seems like too much mucking around! I know that Photoshop can output a tables based HTML, and Fireworks will create divs with absolute positioning; neither appear to be very helpful. Admittedly, I haven't tried much of (DW/FW) (CS4/CS3) since becoming a programmer, so I don't know if new versions are addressing this work flow issue, but are we still double handling things? Can we attach some sort of layout metadata (this is a rollover button, this will be a SWF, this will be text, this logo will hide "xyz" <h1> text etc) to slices to aid in layout generation? are there some secret tools which assist in this conversion process? Or are we still restricted to doing things by hand? The frustration continues when said hand built page needs to be reworked again to fit Smarty Templates/Wordpress/generic CMS. I acknowledge that designers need to be free of systems to be able to do whatever, but most conventional sites have: a header with navigation a sidebar with more links the main content part maybe another sidebar a footer Given the similarity of a lot of components, shouldn't there be a more systematic approach to going from sliced designs to functional HTML? Or am I over-simplifying things? -edit- Mmmmm.... I suppose I will accept an answer, but they weren't really what I was looking for. It just seems like designing the DOM is a bit of holy grail ("It's only a model!"), and maybe with all the "groovy" things you can do with HTML and Javascript, it would be mighty hard work, but with a set of constraints (that 960 stuff looks interesting), some well designed reset style sheets and a bit of... fairy dust? we should be able to improve the work flow. Photoshop's tables by themselves are pretty much useless, I agree, but surely we can take this data, and then select a group of cells and say "right, this is a text div, overflow:auto" or "these cells are an image block, style it with the same height/width as the selected area". Admittedly here at work there are other elephants in the room that need to make their formal introductions to management, but some parts of the designpage workflow seem... uneducated at best.

  • GWT: Getting events in a button in a panel used as a Table cell

    - by mjeffw
    I'm using GWT 1.6. I am creating a panel that contains a Button and a Label, which I then add to a FlexTable as one of its cells. The Button is not receiving any Click events. I see that the table supports determining which Cell is clicked on, but in this case, I want the Mouse events to propagate to the various widgets inside the cell. Any idea on how to do that?

  • Applying styles to a GridView matching certain criteria

    - by NickK
    Hi everyone. I'm fairly new to ASP.Net so it's probably just me being a bit stupid, but I just can't figure out why this isn't working. Basically, I have a GridView control (GridView1) on a page which is reading from a database. I already have a CSS style applied to the GridView and all I want to do is change the background image applied in the style depending on if a certain cell has data in it or not. The way I'm trying to handle this change is updating the CSS class applied to each row through C#. I have the code below doing this: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s.Length > 0) { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } In theory, the data from Cell[7] will either be null or be a string (in this case, likely a person's name). The problem is that when the page loads, every row in the GridView has the new style applied to it, whether it's empty or not. However, when I change it to use hard coded examples, it works fine. So for example, the below would work exactly how I want it to: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s == "Smith") //Matching a name in one of the rows { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } It seems as if the top piece of code is always returning the string with a value greater than 0, but when I check the database the fields are all null (except for my test record of "Smith"). I'm probably doing something very simple that's wrong here, but I can't see what. Like I said, I'm still very new to this. One thing I have tried is changing the argument in the if statement to things like: if (s != null), if (s != "") and if (s == string.empty) all with no luck. Any help is greatly appreciated and don't hesitate to tell me if I'm just being stupid here. :)

  • Get highlighted state for NSButtonCell

    - by dvg
    I have a NSTableView that contains a NSButtonCell in one of the columns. To draw a custom background in neighbor cells (based on NSTextFieldCell) I use isHighlighted method: - (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView { if ([self isHighlighted]) { //here I draw the cell background But for NSButtonCell isHighlighted shows only the button pressed state. How to determine when the NSButtonCell is selected, i.e. when it's highlighted in the row?
