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.

So I am implementing sort of a data table in flutter. it shows data based on time in days in rows and some other variant in columns. so naturally, first row is name of the days, and then in first column are values of the other variant. What properties of GridView.count can I use to make first row and column stay fixed when scrolling the grid. so that you can always see the data variants in screen.
I have gone over all properties of GridView.count but I can't find anything.
PS: I don't want to change to something else Like GridView.builder..... because the code is too far gone with how it renders the dynamic data in the rest of rows and columns.
Please Use data table instead of Grid

I set the row data for the first time, then changed the value of the cell with node.setDataValue and api.refreshCells, but when I set the same row data as the first time, I found that the table was not refreshed, or I just modified it. The value of the cell.
Ag-Grid does not refresh because the rowData I provided twice is the same, and Node.setDataValue does not modify rowData. When I enter the internal comparison of agGridReact for the second time, I find that the two rowDatas have not changed, so there is no Refresh.
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 have a sheet with 18 columns and 137 rows. Some of the columns are empty. When I make the get sheets call (I'm using the C# SDK) the data returned has the following structure which seems anomalous to me ...
Columns --- 19 (the RowID is tacked on at the end of the list)
Rows --- 137 (good) but when I examine the number of cells in the rows, I get varying numbers: 18, 18, 17, 16, 18. It appears to drop the null-valued cells. Is this intentional to drop null cells? If so, why doesn't it always drop null cells? It's a little strange that the cell count doesn't reflect the column count.
The only way I can figure to work around this is to correlate using the ColumnId since there is no guarantee that there will be exactly 18 cells returned for each row.
It appears to drop the null-valued cells. Is this intentional to drop
null cells?
That is correct cells that have never been touched by the user are not sent via the API. This approach will reduce the payload and is beneficial for clients such as mobile.
If so, why doesn't it always drop null cells?
It will always drop the null cells (cells that have not been touched by the user).
However, there is a case where empty cell data is returned. This will occur when a user adds text in a cell, saves the sheet and then deletes the text. It will now appear that the cell is empty but we still store history for this cell so it is not truly a null cell or untouched cell.
The only way I can figure to work around this is to correlate using
the ColumnId since there is no guarantee that there will be exactly 18
cells returned for each row.
If you need to have the cell match up to an exact column (or column position) then we do recommend using the column id as the key.
I am new for iPhone development. I don't have any idea that How show array in Table view? Now problem is that i am coding to display an array of 85 strength. 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:].
