I Have two cell in one row.
I want to show and hide based on condition.
For cell visiblity expression option not showing this is showing only for text/label.
In the script I am adding
if(params["chk"].value == "both"){
this.getStyle().display = "none";}
Any solution please?
You cannot hide a cell. This wouldn't make sense. You can hide the content inside a cell, or you can hide whole rows or columns.
It took me forever to figure out how to set up editing on a custom cell view for an NSTableView. Thanks to StackOverflow I figured that much out. P.S. I was doing all of this in Interface Builder.
I have a single column table in which the cell is a custom multi-control NSTableCellView, with:
name (in bold)
description
detail
It's all text. Set up editability on the name only. The table is sorted by the name.
When I edit the name, it has the effect on the bound model that I expect. The table even re-sorts correctly. However, it's displaying incorrectly. The description and detail (not editable) still show up correctly, but the name (which was edited) is a blank. When I inspect the model, it has the correct updated value. But the cell view itself is incorrect.
This doesn't happen all the time--it typically happens if the cell is re-sorted to the top or bottom of the table, but that may be a red herring and may instead have to do with NSTableView cell caching or something.
I hacked up a workaround in which I assign a delegate to the NSTextField (automatically generated for the NSTableCellView) and intercept the textShouldEndEditing event. For some reason this event is getting triggered twice for a given edit (after I press "enter" in the text field)--once for the actual edit where fieldEditor.string is different from the model name, followed by another event where fieldEditor.string is the same as the model name. If I return false for my textShouldEndEditing handler in the latter case, then the cell contents end up being drawn correctly. That's the hack.
I feel like I'm doing something wrong here though, and that shouldn't be necessary.
Is the textShouldEndEditing event supposed to be fired twice?
When creating a UITableViewController there are two situations that create an "ugly" UX
calling/open it without any data in it --> shows an empty table (i.e. empty rows,UITableViewCell, as many as fit in the window)
calling/open it with fewer rows of content that fit the window --> show the full rows followed by empty rows
I wish to receive the following result:
if there is no data show a picture or view with text - there isn't any data yet or something like that
show only the full lines and no more rows (blank or background image)
Is there a way to achieve that?
To add these effects, you will probably have to make your own UITableViewController from a regular UIViewController, and even subclass UITableView. If you have a regular UIViewController with your filler image/text as the background, you can place a UITableView on top and hook up the delegate/datasource. Now, in your code, detect when there is no data available and set the hidden property of the UITableView accordingly.
As for the following empty rows, you will either have to turn off the row separators (in IB), or subclass a UITableView (can't help you there). Good luck!
I want to edit corresponding labels when the user selects a row.
i have 3 labels in each row in my 1stView . i want to edit the text of those labels
navigating to the another view and there i need to edit those labels text.
one of my labels text is getting from UItextfield declared on the 2nd view and the other 2 labels text is getting from uibuttons title on the the 2nd view.
Now i want to show the labels text in my 2nd view for editing the text pf those three fields??
for more clear i will ellobrate
I have a table in my 1st view, when i click on add button am loading another view(2nd view) where it contains 1 textfield and 2 buttons. I am setting the text of these three fields to my 1stview my each tableviewcell has 3 labels created in each row.
How can i edit those 3 fields??
I would suggest you to make the required strings accessible in both Class1 as well as Class2. So that when you want to get the text from Class2 you can save those strings in your stringVariable and can thus pass on the values to Class1 as well..
After Question Edit:
I will again suggest you to take 3 string variable in class1 and make it accessible in class 2... While you go to class 2 in edit mode/ add new mode you can save the text of textfield and button titles in the 3 strings and can access the same in Class1 and display it in table's cell in Class1. Hope I make it more clearer now
i have done like
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 3;
}
tableview is in UITableViewStylePlain.but it shows correctly 3 data on 3 tableview cell.but after that there is empty tableview cells ...but when i declared UITableViewStyleGrouped, it shows only 3 tableview cells... perfectly...what i have to do disappear empty tableview cell
in UITableViewStylePlain..any help pls?
Your table contains 3 table cells and those cells beneath it are not empty table cells. The row seperators are just drawn based on the previous row height giving the impression that there are more cells than you actually specified.
You could set the separatorStyle of the table view to UITableViewCellSeparatorStyleNone, either in code or in Interface Builder. But doing so disables the seperators all together, so you would have to draw some kind of separator yourself in your cells if you still wanted a grafical separation between the actual cells.
Another option would be to set the color of the separator to the color of the background of the table.
I myself would not worry about this if you're application has a standard table look, as it's default behaviour & users should be used to seeing that. Altough I must admit that I have set the separatorStyle to none in a previous project, because the table had a look that deviated from the standard table look. I did have to draw a fine separator line at the bottom in the table cell.
