I have a angular-mdl table http://mseemann.io/angular2-mdl/table that I'm loading data to from an ajax call. I'd like to allow the user to click on a row and react to that event, but I can't figure out how to determine which row they clicked on (using either the data from the row or an index).
HTML:
<mdl-table [table-model]="tableModel" (click)="WhatToDoHere()" ></mdl-table>

I have requirement of adding a new row for the button onclick.
Example
In the first row at the last cell. I have an ADD MORE button. If I click that button new row should be added below that first row.
Is it possible in jqGrid ??
Yes it is possible. The method addRowData has the needed parameters:
addRowData(string rowid, mixed data, [string position], [string
srcrowid])
Inserts a new row with id = rowid containing the data in data (an
object) at the position specified (first in the table, last in the
table or before or after the row specified in srcrowid). The syntax of
the data object is: {name1:value1,name2: value2…} where name is the
name of the column as described in the colModel and the value is the
value.
More on the method you can read in the Gurrido jqGrid documentation
I have a view panel in xpages and a computed field to show the row-count. I have 2 problems:
1st: how can i count only the rows of the current page of the pager?it seems that viewPanel.getRowCount() gets all rows from the beginning until the current page, so if i have 30 entries per page and i am in page 2, it shows 60 instead of 30.
2nd: even if i achieve the above, the pager only refreshes the view and i can't refresh the computed field or another panel. Can i put the computed field inside the view panel or make it somehow to be refreshed in each page change? i would prefer not to do it with full page refresh if possible...
Given the computed field refresh issue, even if you managed to get a count of rows (eg on a page-scope SSJS variable), it woudln't update the computed field.
It might be easier to to count to rows in the HTML table using clientside javascript ?
something like ..
page onload event :
get the HTML table
get the table rows property (array of rows in the table)
number or rows = that value (1st row = TH (header) row if there is one = row 0)
use javsscript to plug that value into a known DIV
You could also hijack the partial refresh issued from the pager and check for the ID that has been refreshed. If the ID match your view panel's ID, you could do another partial update in order to update another panel.
Example code for hijacking the partial refresh:
var sysHijackPartialRefresh = function(){
XSP._inheritedPartialRefresh = XSP._partialRefresh;
XSP._partialRefresh = function( method, form, refreshId,options) {
if (options){
if (!options.onComplete) {
options.onStart = function(){
};
options.onComplete = function(){
if (refreshId == "<client id of view panel>") {
// issue another partial refresh
XSP.partialRefreshGet(<client id of the other panel>);
}
};
}
}
this._inheritedPartialRefresh(method, form, refreshId, options); }
}
XSP.addOnLoad(sysHijackPartialRefresh);
See http://xpageswiki.com/web/youatnotes/wiki-xpages.nsf/dx/Work_with_events_and_partial_or_full_refresh for more information about partial updates.
The pager should have a "refreshID" property in which you can put the client ID (!) of the panel you want to refresh. Use getClientId() to compute the client ID of the panel.
For the row count: use the XPages debug toolbar (from openNTF) to check for a property of the view panel or the pager which gives you the current page number. If you got that, you can simply compute by using viewPanel.getRowCount() - (page number * number of rows per page).
I use jqGrid v4.4.5 and I want to create it with dynamic columns.
It is filled by "jqGridHandler.ashx" file .
I want send all information(column name,data,...) by JSON .
I search for it in Google but can not find a good answer.
By Click on each node(child) change whole grid(actions and columns...).For example by click on node3 the grid has three columns 'A' and 'B' and 'actions' but by click on node2 grid has columns 'C' and 'D' and 'actions'.
One can use jqGrid to create many different grids, tree grids, subgrids and so on. It's very important to understand whether you want to display grid with 10 rows or with 100000 rows. If you have 100000 rows (or some other large number of rows) you will have to implement server side paging and sorting of data. So if the user would click on the "next page" button the next rows should be loaded from the server. Why you would need to send all colModel data on paging or sorting? So you should clear understand that in server side scenario one need create all structures of grid only once and then one need refresh only the body of grid. So it would be bad choice to send all information (column name, column model, data,... at once).
Only if you have some hundreds or some thousand of rows in the grid and you can use loadonce: true option them you can load once all information (column name, column model, data, ...) per separate jQuery.ajax call and then create jqGrid with datatype: "local" and using data parameter which contains all grid data.
UPDATED: If you need change
// in the example below the grid with id="list" will be created
// with column having name: "c4" in colModel
var $grid = $("#list"), columnName = "c4";
...
var $colHeader = $("#jqgh_" + $.jgrid.jqID($grid[0].id) + "_" + $.jgrid.jqID(columnName)),
$sortingIcons = $colHeader.find(">span.s-ico");
// change the text displayed in the column
$taxHeader.text("New header text");
// append sorting icons to the new text
$taxHeader.append($sortingIcons);
Before your initialize the jqGrid you will need to have the information for your colNames and colModel properties of the jqGrid.
So in short, you will request the information from your server, once you have successfully retrieved that information you can then build the jqGrid and then the jqGrid can go and fetch it's data.
The following post has some example code on the client side:
jqGrid and dynamic column binding
I'm using jqGrid's filterToolbar method to let users quick search/filter the grid data. I'm using loadonce: true and datatype: local as my grid configs. I have a drop-down (select) filter type for one of my columns, which works fine.
Problem is when i try to update a row (using setRowData) that is not visible (because the filter/search result is hiding them), the row doesn't get updated when I reshow them by clearing the filter.
Any suggestions? I've tried triggering the reloadGrid event too, no luck.
Cheers
Update 1 - Reproducing the problem:
Here's how to reproduce the problem, using jqGrid's official demos:
Step 1
Browse to the jqGrid's demo page, and open the demo named 'Toolbar search' under 'New in version 3.7'
Step 2
In the demo grid, filter by the code column with the value 575878 so that only the first row is shown on the grid.
Step 3
Bring up the javascript console and update a row that's not currently visible, in this example update row 2:
jQuery("#toolbar").jqGrid('setRowData',2,{item_id:2,item:'blargh',item_cd:12345678});
Step 4
Unhide all the rows by clearing the filter value, and see that row 2 has not been updated!
Anything I'm doing wrong here? Possible workarounds?
You misunderstand how the grid are build. Grid can contain hidden columns, but no hidden rows. If one filter grid the full grid body will be removed and only the filtered rows will be inserted.
The method setRowData can be used to modify any row of the grid, but you can't modify something which is not present in the grid.
If you use local grid (datatype: 'local') then the data which you save in the grid will be saved in two internal jqGrid parameters data and _index. So you should modify the data object. To fill grid with modified data you need call .trigger("reloadGrid").
So if you want modify columns item_id, item and item_cd of the grid's data for the rowid=2 you can do the following steps.
1) Get references to the internal jqGrid parameters data and _index:
var $myGrid = jQuery("#toolbar"),
data = $myGrid.jqGrid('getGridParam', 'data'),
index = $myGrid.jqGrid('getGridParam', '_index');
2) Get reference to the object which represent the rowid which you need:
var rowId = '2',
itemIndex = index[rowId],
rowItem = data[itemIndex];
3) Modify the data item like you as need:
rowItem.item_id = 2;
rowItem.item = 'blargh';
rowItem.item_cd = 12345678;
4) Refresh grid contain (if needed) by reloading the grid
$myGrid.trigger('reloadGrid');
I am using Ext.grid.gridpanel.As in rowclick event, we can handle row click of grid..Is there any event to handle column click of grid?
i want to select a particular column of grid.
There is no special columnclick event on the gridpanel or the selection model, but you can listen to the
cellclick : ( Grid this, Number rowIndex, Number columnIndex, Ext.EventObject e )
event on the gridpanel itself - irrespective which selection model you use. Looking at the columnIndex you'll know which column has been clicked. If you want to react on clicks onto the header row, use the headerclick event instead.
