I am wondering if there is a way to effectively lock a column in Ag-Grid so that the column is always the very last column no matter what.
Background
What I am ultimately looking for is to avoid the blank space after the last column if the grid size is wider than all column width combined. This is to give the grid a consistent, professional look especially considering even/odd rows are rendered usually in different color. I would prefer the blank space also has that alternating background color.
Given there seems to be no grid property that forces the grid to render the blank space at the end as a pseudo column, I am therefore considering to add a pseudo column manually in such a way that:
the pseudo column has no header
the pseudo column has no data
the pseudo column is not sortable (achieved via sortable: false)
the pseudo column is not manually resizable (achieved via resizable: false)
the pseudo column is the only column which has suppressSizeToFit: false
lock the pseudo column to always be the last column so that user cannot drag a column to the right side of it
I've found a way to achieve everything apart from the last item in the above list. I know I can suppressMovable: true but that only ensures the column itself is not draggable, it does not prevent user from dragging a column to the right side of it.
Effectively, I am looking for something similar to lockPosition but instead of locking the column to the front I want to lock the column to the end.
Keep an eye on currently open AG-3326 issue in ag-grid backlog https://www.ag-grid.com/ag-grid-pipeline/
"Allow locking ( lockPosition ) a column to always be either the first or last columns (currently only the first column is supported)"
What I am ultimately looking for is to avoid the blank space after the last column if the grid size is wider than all column width combined
You could use sizeColumnsToFit() API for columns to adjust in size to fit the grid horizontally. Using this API, there won't be any blank space after the last column, but make sure you have not specified the width for at least one column. This is the column that will expand/shrink to fit the size of the grid.
Call sizeColumnsToFit() after the gridReady event has fired.
Here is an effective workaround to lock the right-most column until AG-3326 is implemented.
onColumnMoved: params => {
const columnCount = params.columnApi.getAllColumns().filter(c => c.isVisible()).length;
const maxIndex = columnCount - 2;
if(params.toIndex > maxIndex) {
params.columnApi.moveColumnByIndex(params.toIndex, maxIndex);
}
}
Any column that is moved to the right of the 'locked' column is immediately moved to the left of the 'locked' column.

I have a gtk treeview (inside a GtkScrolledWindow) with two columns.
If I set both columns to the default sizing policy, I have a horizontal scrollbar for the treeview but the columns can't be sized down by the user, which is impractical.
If I set both columns to setSizing Fixed, fixed width 120, I get a nice display and the columns can be resized, but there is no horizontal scrollbar in the treeview (since the columns size down to fit in the width of the treeview I guess).
If I set the first column to setSizing fixed, fixed width 120, the second one to automatic, only the second column is displayed (???).
I would like that by default the first column takes let's say at most 60% of the display, the second column can go all the way and I have a horizontal scrollbar. Certainly I want the user to be able to resize them up or down, not as with the default policy, that you can resize them down!
That's why I tried the first column fixed, the second automatic, it was promessing but I don't understand why the first column is not displayed at all in that configuration.
I add the cell renderers with packstart true, I tried false but it didn't change anything, also I tried setting the expand for the columns to true or false, which didn't have any effect.
Note I'm using the gtk2hs haskell bindings but I'm certain it would be the same in any other gtk binding. Just mentioning if people will ask for code samples.
I'm pretty sure this is a common problem... I'd say nautilus is fixing it the way I'd like to fix it, but I think digging in the nautilus source is going to be quite long...
EDIT well i've discovered the cell renderer's ellipsize setting also has an effect. Setting it to end for the first column and none for the second should be what i want but then the first column is very small and cannot be expanded through resize...
EDIT2 well for now i've moved to word wrapping for the cell renderer, that way i don't have to bother with a horizontal scrollbar... Still curious for the solution to that question though.
I have a TreeView whose columns are all expandable with fixed-mode sizing. I would like to restore the widths of the columns when the user restarts the app. It seems that calling set_fixed_size is the way to do this, but:
If I set only the widths of the columns that the user resized, then the actual column widths end up different from what they were before.
If instead I set all column widths explicitly, then all columns behave as though they had been resized by the user, which is not ideal.
Is there a way to restore the column widths that gets around these problems?
It turns out that expand interferes with fixed_width. In my case, the solution was to set fixed_width and expand=false on columns that the user resized, and expand=true on the others.
currently i have the following chart:
It currently contains one column (blue one) and a range column (white one). But what i really need is a chart which looks like the following:
So the white column should be overlapped by the blue column. I tried to change the range column to a normal column and changed the "CustomAttribute" PointWidth but was not able to get my chart looking like the needed chart.
Does somebody knows how to do that? Thanks
#glh: I know that, it currently looks like this (changing the white range to column):
ANGEFALLEN = blue column
EINGEPLANTV1 = white column
Problem is that the white column is now right to the blue column.
If i change the order of the chart data the blue column ins right to the white column. But i need the white column to be behind the blue column like shown in the second picture of the main post / question.
Followup 25.04.2013:
The chart should look like this:
I need to move 1/3 of the white column behind the blue column so that 2/3 of the white column is still visible. The blue column has to be in the foreground and the white column in the background.
Overlapping Series:
Change the "overlapping" series to a "Range Column" chart type. This will allow you to layer the two series on top of each other.
Once you do this, you will notice that the series will get two value drop-downs:
Set the "Low" drop down to an expression with the value of 0.
Set the "High" drop down to the value you would like to represent.
Offset Series Position:
I am actually not sure if this is possible in SSRS. However, you can play with the widths of the layered series to achieve a similar effect.
Set the PointWidth propety of the series (under CustomAttributes) either larger or smaller than the default .08, depending on your desired effect.
Here is a quick mockup I put together. It isn't exactly what you were looking for, but maybe it'll get your creative brain juices flowing.
You should be able to drag the values around in the values box or there will be a blue up or down arrow to alter the order your data is displayed. See below for an example of what you will see when you select the charts data.
In my table I have repeating value.
I have put isPrintRepeatedValues=false to avoid the repeat values. It was success but I found that the left border is missing for the left cell in a row.
How to make to cover his line for a repeat row only?
The result would be as at the picture (highlighting area) below:
I'd like to create a 'header' label that 1) is centered over the cross-tab and 2) grows with it. Unfortunately, CR 2008 (or earlier for that matter) doesn't have this feature.
In image (below), I've added a text field above the cross-tab, but I can't think of a way to get it to grow/shrink (horizontally) with it.
If you're able to calculate, say by a summary function, the number of columns you will have then you can do this:
In your crosstab, check to see the width of your columns. The columns should be set widths. Edit: The crosstab adds some padding, so you will have to figure out the column width by measuring in Crystal with another field and eyeballing until it's close enough to work
Right-click on your label, and hit "Size & Position".
Add a new formula for the "Width". The X,Y positions should stay the same.
Use the summary function (You could create a SQL Expression or formula that only shows the month/year of your date fields and then distinctCount() them) to find out how many columns you will have multiplied by the width of each column. This will take some trial and error for sure, but I don't see why it wouldn't work.
