I have ExtJS Grid In which I have Columns called "Mobile Number".
I have made simple thing here When I edit more than 2 rows and If I Modify the Column "Mobile Number" It will be checked whether is it Exist in Grid or Not.
If Duplicate Number found, I will give Message that the Input Mobile Number is already Exist and
reloading the whole grid so all edited data will be gone.
But, I want the non-duplicate data back was edited.
So, How can I keep my non-duplicate data as it is after reload the whole Grid.
I just want to remove duplicate row where found duplication and other edited rows keep as it is.
Can I use this RowEditor plugin for ExtJS 2.x compatible.

To find duplicate data use afteredit event of Ext.grid.EditorGridPanel on that event you will get current record, so just display message and add empty value in that field
You should use a validator for the mobile number field that detects duplicates and refuse the duplicate number. So you don't have to reload the grid.
If you want to reload the grid anyways, you could get the dirty rows before doing so and store/reapply them afterwards.
To get the dirty records you can use the getModifiedRecords() function of the grids store. Use the commitChangesfunction of the store to apply them after validation/processing.

I have the gridpanel in extjs with filter in the header so the end-users can make the filter, updating row and then make another filter and continue updating row ...
After finishing updating the rows, the user will click on save button and send all the data to server for updating, but i can only get the visible row in gridpanel.
Could sombody show me how can i get all the updated rows (which is hidden by filter) in gridpanel using extjs?
Thanks in advance.
After checking the api document from Ext JS, I can retrieve all records including the filtered out one using getDataSource function.
I'm new on reactjs, and I want to create a table to show some data. In the project I'm working, we are using Ag-Grid datagrid.
I already have created it with basic usage, but my question is:
Supose I have 100 rows as enter, how I can display in datagrid just the 10 firsts?
I stil wanna load all data (for filtering, sort, etc), just don't wanna show all by default.
I'm looking at documentation and do some search, but don't find the proper way to do it.
Edit: I already see the pagination options (the default solution provided by documentation), but in my case, at least for now I don't want pagination. Just wanna render the X first rows (the extra will be ommited in table, but have to be loaded in UI, if not, I could use autoHeight).
Thanks in advance.
I'm assuming you are using the Client Side Row Model and not loading data from a Server. In which case, the easiest way to achieve this would be to show the 10 rows, and add more rows (depending on when you want to load them) via Transaction Updates, please see the documentation on this here
you can use pagination:

Folks,
I am using ng-grid to display a list of items.
I want to give my users ability to rearrange the rows in the list.
i.e move the rows up and down as they please.
Now,
However when I update the grid data in the backend i.e say change the index of a particular row, that row does not automatically change locations in the front-end.
What am i missing here ?
I have created a plunker to describe the problem
http://plnkr.co/edit/s1hrTSqF2zeZo3Btaln0
The grid doesn't use the index of the array to order it, so even if you are changing it, because the data is still there nothing happens.
What you could do is define an order field and update the value then changing the values as shown in this plukr. The order field you can hide it from the grid if required using columnDefs to explicitly defined which column should be shown.

I have a problem with extjs gridpanel dragdrop.
the scenario is as follows:
The gridpanel is initially rendered by loading a remote store.
Then, the rows are added, updated dynamically.
Drag drop feature is implemented on "render" event of gridpanel.
Drag drop works fine for the originally retrieved rows from the remote store.
but when i try to use drag drop for the newly added or edited rows, it doesn't work.
I am getting the following error on firebug:
Index or size is negative or greater than the allowed amount" code: "1
This is may be because , the newly added rows are not taken as a part of the store . I tried changing the event to "click" but it doesnt work that way..
Please please suggest a solution for this fast.. Its needed urgently.
Thanks,
Shreya.
I know 2 methods for drag and drop in ext, one of them is only for grid rows, the other one that I'm using is with setting dragzones and dropzones. With that method, the only thing you have to do is catch an event which is fired when you add new rows to the grid. In that event, set every new row to be a dragzone (so it can be dragged). That's what I did in a similar situation. Hope this helps..
By the way grid rows don't have a .el (DOM element attached to the Ext component, which is the row in this case). So you'll have to create a div for each row component and then use the initializeDropZone(row[x]), where row[x] is the new added row.
I have a column in a grid with editor as combo-box.
When the grid is loaded then all the column values get displayed properly.
The issue is, when user clicks at the column (having combobox as editor) to edit it then the column value becomes null as shown in the attached screenshot.
I understand that the value becomes null as the store of combobox has not been loaded yet.
I can not use autoLoad true due to the heavy amount of data present in the combobox store. Moreover, even if I use autoLoad:true for the store with paging in it, then that too safeguards only those values which are present in the first page and not all.
Thus, how can I maintain the value in grid column when that value is not present in the store of combobox used as editor for the column?
Could anyone guide at this?
PS: I am using ExtJS Ver 4.0.2a
I have been able to find a solution for this.
It has more to do with the version of ExtJs. If we upgrade to 4.0.7 and then use forceSelection:false for a combobox then things work fine as expected. That is, the combo-box accepts a value which doesn't exist in its store and doesn't set the current value to null.
Hope this helps someone else too looking for something similar.
I would suggest having the grid record contain both that columns value, as well as display value. If the combo store lookup is unable to find a matching value (because that combo store hasn't been loaded yet), then revert to showing the display value stored with the grid record.
You might also need to have the afteredit event on the grid update that grid records display value after that column is edited for a particular row.
