Now i want to show in slots in table view. for example when first time view did load then table show 10 element and in 11th row show a button Next. When click on Next then show next 15th element and in 16 th row show two button.One is next and second is previous. When click on next then show next 15 element and when click on previous then show previous 10 element. How do and where do in coding part?
I am get data in array from XML parsing. That array i have shown i view did load.In number of row i have written [tmparray count]+1. Tmparray have first ten element.
What i will do next? Thanks in advances..................
Try creating an array method that returns your content array filtered with [NSArray filteredArrayWithPredicate:].

I have a UICollectionView displaying a UITextField inside each row. The number of rows may be dynamic, and what I want is to display the number of times the specific cell is being clicked and display count on each textfield simultaneously.
I have tried setting a variable for number of clicks and I've tracked each index-path so the count is increased but,
I'm unable to increase their own value on their own cell.
Use this right after you increment the variable:
collectionView.reloadItemsAtIndexPaths(indexPath)
I only have this logic maybe it would help you a little bit, I may
provide you with code after I convert my logic to code.
If you have already stored the number of clicks then you must make an array to append the cell which has been clicked and filter the indexpath.row that you will append in this array which you'll get in didSelectRowAt.
You need to filter them such that, if the selected cell has previously been appended in the array it needs to be removed from that index and appended to the last index of the same array.
So that you can access the array of your clicked row, to show them on each of their cells textfield.
I am building a screen where the system jumps to rows in a TableView based on error conditions. Not all rows will be touched. My table view can hold approximately 23 rows. When there are less details than that I have no issues.
However when there is more and the first item in error is off the visual flow, I get weird rendering on the first access only.
In this example, I have 63 rows of data, and the first row that needs to be reviewed is like 35.
When the system determines the row it needs to access I jump there by first selecting the row and then scrolling the table to it:
When I initialize the table:
tableView.getSelectionModel().setCellSelectionEnabled(true);
tableView.setItems(sorted);
tableView.setEditable(true);
In the call to select the next row:
int nextRow = determineNextRow();
tableView.getSelectionModel().select(nextRow, columnToEdit);
tableView.scrollTo(nextRow);
At this point the table scrolls off top & bottom. And the display looks like this:
After entering the amount, it drops to the next line and everything looks OK.
I am not quite sure how to correct the initial landing.
Thanks.
I have developed a small application in which I have a row repeater where I will display the recently created records.
Suppose I have some 150 records in a row repeater.
Now the problem is I scroll down to see the 100th record in the row repeater
and after viewing the 100th record I will go back by clicking on back button.
Now if I again click on the row repeater the page is not displaying from the starting record by default its showing from the 100th record means I again need to scroll up to view the 0th record.
How can I overcome this issue?
You can
ensure that the RowRepeater (or it's surrounding view) is destroyed on back and recreated on enter (only way known to me to handle your requirement with UI5)
use jQuery.scrollTop() on re-entering the view with your row repeater
var oRR = sap.ui.getCore().byId("myRowRepeater");
jQuery(".sapUiRrPage", oRR.getDomRef()).scrollTop();
I currently have a List TableView where I can place check marks on any of the Products in that list. Right now, there is no outlet to handle the check marks. What I'd like to do is once the user places check marks on Product names in that list, press a button which would pass those Products' details over to a new tableview, displaying the details of those Products in a side-by-side column-type of tableview for a side-by-side comparison of the 3 Products' details. I could really use some help on the following and any help provided would be much appreciated.
1) Take the check marks and press a button to send that to a new view. I have no idea how to associate and connect those check marks to a button and then program that button to send the details to a new tableview.
2) Create a new view with a tableview capable of displaying 3 side-by-side columns in a tableview. I have read some about creating tables that appear to have multiple columns, but I'm not exactly sure how this is achieved.
Any help would be much appreciated. Thanks.
I'm not sure about number 2, but here's how I'd handle number 1:
Store the "check mark" as an attribute of each Product object in the array where your first table view is getting its data. Then, when you push the next view controller, populate an array by checking which products have a check mark attribute and adding them to a new array for your second table view's data source.
I am using UITableView with Griding Functionality. When scrolling, at the last column it automatically comes at First cell. What should I do to resolve this problem?
It sounds like you're looping your data source.
A tableview has some data structure that provides both the data and the structure of that data so that the data is ordered into rows. The simplest data structure would be an array. The first row would display info at array element zero, the second row at array element 1 and so on.
If the last row of the table displays data from first row, then you have somehow looped the array index back to zero. I can't say exactly how you've done that without seeing the code.
