I have a datagridview that is only two or three rows long. It has 7 text columns, one for each day of the week (Monday - Sunday). I'm creating a scheduler, so basically on the left side I have added text to the row headers to assign to it. I.e. Enabled (let's say for Tuesday), start time and end time. This allows the user to schedule as need be.
Here's a picture of it right now:
What I want to do is possibly change the enabled row, or the start/end time to a particular type. So the enabled will be a checkbox and the start/end times will be drop down menus instead of these text boxes.
My question is, what's the "best" way to add a row of a certain type? Obviously columns are done easily, but is there a common method for a row type other than looping through and adding individual cells of that type to the datagridview?
The type of each cell can only be pre-determined by the column, not the row. As a result, you're going to have to add each cell individually. You can actually put a cell of any type anywhere you want. You simply create a cell of the desired type and assign it to the Item property of the grid, e.g.
myDataGridView(columnIndex, rowIndex) = newCell
You will simply have to use a For loop to do that for each valid column index with a single row index. Note that you'll have to create a new cell for each column, not reuse the same one.

I have a PivotTable in compact form layout (default layout) with multiple row area fields. This results in multiple grouping levels with buttons to collapse or expand rows.
I want to modify a cell depending on the grouping level the row is in.
How can I check in which row the cell is in?
The only idea I had so far was to check the value of the leftmost cell in the corresponding row and compare it with each item from each rowField.
But I guess there is a smarter way?
It took me a while. But at the end I just needed PivotCell.RowItems.Count
Depending on the Count result I can new manipulate the cell.
I have a list of stock prices for several stocks. Some of the values are missing due to weekends, holidays and probably other reasons.
The gaps are not consistent. Some are two days and some are more than that.
I want to fill the gaps with the last known value but not at the end of the list.
I have tried in Excel to test a few cells below and if it's now empty, do the fill. The problem is that due to the inconsistency of the gaps, it's a tedious task to change the function for all the cases.
Is there a way to test for the end of a list?
UPDATE - added a screenshot.
See this screenshot. I want to fill where the blue dots are. The red dots are at the end of the list and I don't want to fill those cells.
I am looking for a way to detect the end of the list and stop the filling when the end is detected.
I think this is pretty difficult in OpenRefine and probably a different tool would work better. The main issue is that OpenRefine does not offer the ability to easily work across rows so 'summing a column' (or part of a column) is tricky - this is mentioned in https://github.com/OpenRefine/OpenRefine/issues/200
However, you can do this by forcing OpenRefine in Record mode with the whole project containing a single record. Once you've done this you can access all values in a column using syntax like:
row.record.cells["Column name"].value
This gives an array of all the non-blank values in the column. Since this ignores blank values, in order to have a true view of the values in the column you have to fill in blank cells with a value.
So I think you could probably achieve what you want as follows:
For each column you are going to work with do a cell transform to put a dummy value in empty cells - e.g. if(isBlank(value),"null",value)
Create a new column at the start of your project and put a single value in the very first cell in that column
Switch to Record mode
At this point you should have a single 'Record' in your project - e.g.
You can now access all cells in a column using syntax like row.record.cells["Column 1"].value. You can combine this with 'forRange' to iterate through the contents of this array, using the row.index as the marker for the current row.
I used the following formula to add a new column to the project:
with(row.record.cells["Column 1"].value,w,if(forRange(row.index,w.length(),1,i,w[i].toNumber()).sum()>0,"a","b"))
Then...
Change back to 'Row' mode
Remove the 'null' placeholder from the original column
Create a facet on the 'fill filter' column
In my case I filter to 'a'
Use the 'fill down' option
Remove the filter
And remove the 'record' column
Rather a long winded way of doing it to say the least, but so far I've not been able to find anything better while not going outside OpenRefine. I'm guessing you could probably compress steps 5-11 into a single step or smaller number of steps.
If you want to access the array of cell values using Jython as suggested by iMitwe you need to use:
row["record"]["cells"]["Column 1"]["value"]
instead of
row.record.cells["Column 1"].value
(step 5)
I am doing this on the top of my head, but I think your best chance my be using the fill down option in record mode:
first move your column to the first column and switch to record mode.
then use the following GREL: row.record.cells["data"].value[-1] where data is the name of your column
The [-1] will take the last value and fill the blank. For the case with the red dot, since there is no value it should remains empty. Let us know how it goes.
Unless there's something I am missing or not seeing...
I would have just sorted reverse (date ascending) on the Date column, then individually use Fill Down on each column, except for that last column where you could then use a Date facet on your column Date to specify the exact Date range you wanted to work with, then fill down on that last column, then remove the Date range facet.
I'm trying to get a msgbox when a value is duplicate base on 2 columns. The first column Value can be repeated but the second column will determine if it's a duplicate or not.
i.e.
Column B = Code,
Column L = Month
The user can enter the Code several times, but if he enters it on the same month I want the msgbox pop up
Is your intention to warn\inform the user? If so, I would do this without a macro. I would use conditional formatting to make the cell change color whenever the duplicate information is entered.
Create a column on your worksheet with a formula that concatenates the information in column B&L the formula would be =B1&L1 (copy this formula down the table). You can hide the column so nobody sees it. For this example, let's say you used column "M".
Select the entire Code or Month column (or both) and click the CONDITIONAL FORMATTING button on the Home tab, choose NEW RULE, USE FORMULA TO DETERMINE WHICH CELLS TO FORMAT, then enter the following formula: =COUNTIF($M$4:$M$1000,M1)>1 (note I am assuming your range of data is less than 1000 records, otherwise increase that number). Set the format to something like a red fill and instantly duplicates will be flagged. The user will also be able to quickly locate the record where this combination was already entered as that will turn red too.
If you really do want a macro to do this, you could simply write a loop to compares the active cell value of B(activerow) & L(activerow) to each previous B#&L# combination. If a match is found, use the intersect method to pop-up a the message. Here is really a good article about the intersect method: http://www.ozgrid.com/VBA/vba-intersect.htm.
I am trying to sort data based upon either color (RGB(186,200,8)) or value ("AMP") within a cell. That part is easy but the problem comes when I want to look for the same value/color in multiple columns (it can occur up to four times) and put the ones with all for equal to the value at the top and then three values next and on down to no match.
I'm not sure how to go about, I think a for loop and/or else would work but I can't come up with one. Any suggestions?
My suggestion would be to calculate "hit" value for the row and based on that you could do the sort easily. For instance if you have two matches on the row value for that row = 2 etc. after each row validated just sort by the value and clean the data.
I am trying to set the alignment of a specific cell in a row/column to be right aligned. However I do not want to set the whole row, or whole column to right aligned. Is it possible to set the cell only? From what I've seen online I'm starting to think it isn't possible.
You would need to hook up to the RowDataBound event. This fires as each row is databound. Check that the row is a data row (as opposed to a header or footer). Then check the value in the column you are interested in. If the value meets your criteria for right justification then apply that to the column in question.
Note if you are using AlternateItemTemplate then check both Item rows and AlternateItem rows.
I've used this method to say change the backround colour of values that fall outside a range.
