My layout constraints are
new MigLayout("wrap 4")
Am trying to dynamically place components.
Use Case
Even if the constraints for the component(Comp4) are specified as span 3 1, the component should be automatically added in the next row even though there is 1 column left because the column span(3) is greater than available column(1) in 1st row
are there any constraints which can specified to handle these kind of use cases?
With MigLayout("wrap 4") you are using wrap as a container constraint. In this context, it is a convenience auto-wrapping constraint. If you have a layout that happens to have four cells per row that you can use it. If not, than you should use component wrap constraint. The container wrap is not meant to dynamically adapt itself.

Have used Expander in one column of React-table. On expanding a different row of table i want to display different subComponents. My subComponent has another react-table. So the issue is when two rows are expanded , the subComponent react table gets the data source acc to the 2nd row and thus it updates the same in the 1st row subComponent as well. I want to have different data sources according to the row.
Also tell how to give Column accessor value with the Expander button in the same cell.
I have given the data dynamically to the subComponent react table that is doin fine.
you have to use React.CreateElement and pass your SubComponent And Separete Store (if exists)
for more information about creating dynamic component see React Site
This is a question, How to implement the feature: One cell on the same row affects another cell.
For Example:
The cell 1 inputted 100, The second cell must less than 100, It means the second cell value must less than the first cell.
How can I implement this feature?
My experience:
All the data store into redux(for example), then check the different cell base on redux data
I have an ag-grid (free reactjs version) with lots of columns and records to load.
Some columns are not necessary, so the user can drag the columns out of the grid (and hence hide them). This is fine but how can the user show the hidden columns again without refreshing the page?
I don't want to suppress column drag, just a way to undo the hide without refreshing.
Any advice?
Shameless plug: The enterprise version has this feature in two places, Tool Panel and Column Menu.
However, thankfully it is rather easy to implement this feature yourself using a single columnApi call, well... one of these:
resetColumnState()
This will reset the state of the columns to what you initially defined them as. It will basically make everything visible again
setColumnVisible(colKey, visible)
Just pass in the colId of the column (usually what you passed in as 'field'... but it could be different depending on your set up) and a truthy or falsey value and this will show/hide the column
setColumnsVisible(<Array> colKeys, visible)
note the s - other than that it is the same as before, but you provide an array of colKeys that you want to all be hidden or shown. If you wanted to provide an array of all your columns with another array of whether they should be shown or not then use the last option here setColumnState
setColumnState(<Array> columnState)
This is probably overkill for what you are trying to do, but this will allow you to set the state of all the columns, whether they are visible or not, pinned to different sides, fixing the widths, etc.
Basically I can see you doing one of two things:
Create a button that will make all the columns visible and call gridOptions.columnApi.resetColumnState() when it is clicked
-- OR --
Create a list of check boxes that will listen for a change and call one of the other functions. This list could be outside of your grid, or even inside of your grid in a Custom Filter Component (find the athlete column of the first example to see what I mean.)
This is a bit of a general question into the possibilities of ui grid. I have had tremendous success with ui grid thus far. Now I have a use case where I want to switch the rows and columns of the grid.
Basically, I would like the headers to be displayed 'vertically' in the first column and to have the rows become columns.
Is this possible with ui grid?
As far as i know UI-grid doesn't support this. I doubt if you can do that. May be try building ColumnsDef and Data dynamically and pass it to gridOptions. Or else add extra column and this should be the first column where you will pass all the header values. Change the background of the cells to look like header cells. Now add second column where you pass the entire first row values. Hide the original header row completely. see now u got your required grid........ :)
I have a very large grid with many columns. When the user clicks on the button, it calls a function which analyzes the whole store - cell by cell, if it finds no changes in a particular column, it hides it, othewise the column stays visible. Very often quite a large number of columns get hidden, but as I can see, this operation - column hiding with all this rendering - is very "heavy", so that my browser may alert, that the code runs for too long.
I do hiding like this:
var cols=grid.headerCt.getGridColumns();
Ext.each(cols, function (item, index, all){
if(condition) item.setVisible(false);
});
I tried to use Ext.suspendLayouts() and Ext.resumeLayouts(), but it leads to a bug. Even though operation now runs faster, instead of column hiding only columns' titles get hidden. So, I need a more optimal and working solution.
suspendLayouts() and subsequent resumeLayouts() is one of the ways to go. You only need to call grid.getView().refresh() after you resume the layouts.
Another option would be to call reconfigure, however, this removes the "hidden" columns from the columns menu.
