I'm trying to select first row after grid sorting using the following code
dhtmlx.image_path='./codebase/imgs/';
var main_layout = new dhtmlXLayoutObject({
parent: document.body,
pattern: "1C",
cells: [{id: "a"}]
});
var selectionGrig = main_layout.cells('a').attachGrid();
with (selectionGrig){
attachEvent("onAfterSorting",
function(index,type,direction){
selectionGrig.selectRow(0);
}
);
setIconsPath('./codebase/imgs/');
setHeader("Show,Group,Date,Time,C1,S,C2,L,H");
setColTypes("ch,ro,dhxCalendar,ro,coro,ro,ro,ro,ro");
setColSorting('int,int,date,time,int,str,int,str,int');
setDateFormat('%d %M %Y','%Y-%m-%d');
updateFromXML('./data/tmp.xml', true,false, function(){selectionGrig.groupBy(1);});
init();
}
}
but it select always the same row after sorting whatever the position of this row but not the first one.
Try to call the next code from onAfterSorting callback
selectionGrig.selectRow( selectionGrid.rowsCol[0] );

I have a treeTable with editable cells within the expanded rows. The editable cells get a dirty flag after editing (in the example the background color is set to red).
The problem i'm running into is that i found no certain way to update the dirty flag on expand/collapse (edited cells get the css class 'edited-cell').
At the moment the code looks like that:
// each editable textfield gets a Listener
textField.attachLiveChange(
var source = oEvent.oSource;
...
jQuery('#' + source.getId()).addClass(EDITED_CELL_CLASS, false)
// list with cell ids, e.g. "__field1-col1-row1"
DIRTY_MODELS.push(model.getId()) //*** add also binding context of row
)
// the table rows are updated on toggleOpenState
new sap.ui.table.TreeTable({
toggleOpenState: function(oEvent) {
...
this.updateRows() // see function below
}
})
// update Rows function is also delegated
oTable.addDelegate({ onAfterRendering : jQuery.proxy(this.updateRows, oTable)});
//http://stackoverflow.com/questions/23683627/access-row-for-styling-in-sap-ui5-template-handler-using-jquery
// this method is called on each expand/collapse: here i can make sure that the whole row has it's correct styling...
// but how to make sure that special cells are dirty?
function updateRows(oEvent) {
if (oEvent.type !== 'AfterRendering'){
this.onvscroll(oEvent);
}
var rows = this.getVisibleRowCount();
var rowStart = this.getFirstVisibleRow();
var actualRow;
for (var i = 0; i < rows; i++){
actualRow = this.getContextByIndex(rowStart + i); //content
var row = this.getRows()[i]
var obj = actualRow.getObject()
var rowId = row.getId()
updateStyleOfRows(obj, rowId, actualRow)
updateDirtyCells(rowId) //*** how to get the binding context in this function???
}
};
// update Dirty Cells in function updateRows():
function updateDirtyCells(rowId){
for (var i = 0; i < DIRTY_MODELS.length; i++){
var dirtyCellId = DIRTY_MODELS[i]
//*** make sure that only the correct expanded/collapsed rows will be updated -> depends on the bindingContext of the row
jQuery('#' + rowId).find('#' + dirtyCellId + '.editable-cell').addClass(EDITED_CELL_CLASS, false)
}
}
This doesn't work correctly, because the ids of the cells change on each layout render (e.g. collapse/expand rows). Please see attached image.
Let me know if i should provide more information.
Is there a way we can delete rows from a wijmo grid running within a loop and refresh the grid with new data. I tried with the following approach, I can see the rows getting deleted while debugging but after the loop ends the grid is refreshed with old set of data.
self.delete = function (obj, event) {
var pagesize = $("#pageDisplay :selected").val();// 5
var pageSizeDiff = defaultPageSize - pagesize;//5
var $grid = $("#Grid");
var newData = $grid.wijgrid("data");// array of 10 objects
var i = 0;
while (i < pagesize) {
newData.splice(pageSizeDiff, 1);// delete from 5th row
$grid.wijgrid("data", newData);
//refresh grid
$grid.wijgrid("ensureControl", true);
i++;
};
};
I am not sure why you are setting the new data in the loop. Ideally, you should delete the rows in the loop and then, set the new data.
While working with JqxWidges I met a problem with exporting nested grids which use one JSON as a source file. The common solution doesn't work. Actually it exports only parent grid colums.
$("#excelExport").click(function () {
$("#jqxGrid").jqxGrid('exportdata', 'csv', chartName + ' ' + date);
});
One of the existing solutions (http://www.jqwidgets.com/community/reply/reply-to-export-data-from-a-nested-grid-13/) propose to push nested rows into data array while calling initrowdetails function.
Yes it works! But only for nested grids and in case when this grid was selected.
So, from this step I am moving to next aproach:
To collect all necessary data into array using initial JSON (prevent you from gathering only separate selected data);
To initialise parent grid columns with all existing data and mark nested columns as hidden. Then when export don't forget to add true parameter to export both non/hidden columns;
Use standard export with custom array parameter;
That's it!
Data collecting:
var toExport = data.allClientsCountChart;
var exp = new Array();
for(var i in toExport){
var client = {};
var countr = toExport[i].countries;
client[labels.clientType]=toExport[i].clientType;
client[labels.clientTypeCount]=toExport[i].clientTypeCount;
exp.push(client);
for(var j in countr) {
var country = {}
var detailes = countr[j].clientDetails;
country[labels.countryType]=countr[j].countryType;
country[labels.clientsNumber]=countr[j].clientsNumber;
exp.push(country);
for(var d in detailes) {
var det = {}
det[labels.scriptName]=detailes[d].scriptName;
det[labels.clientsCount]=detailes[d].clientsCount;
exp.push(det);
}
}
}
Export:
$("#excelExport").click(function () {
$("#jqxGrid").jqxGrid('exportdata', 'csv', chartName + ' ' + date, true, exp, true);
}
And don't forget to set the fifth pafameter into true to export hidden columns.
No doubds, it looks hardcoded. But it works for me.
So, if you have a good solution - please leave a comment!!!
I've looked at this other question, but can't get my select box to work correctly:
Binding initial/default value of dropdown (select) list
I've got the following Game object:
function Game(visitingTeamDetails, homeTeamDetails, game) {
if (arguments.length > 0) {
this.VisitingTeamDetails = visitingTeamDetails;
this.HomeTeamDetails = homeTeamDetails;
this.GameId = ko.observable(game.GameId);
this.HomeTeamName = ko.observable(game.HomeTeamName);
this.VisitingTeamName = ko.observable(game.VisitingTeamName);
this.SportTypeName = ko.observable(game.SportTypeName);
this.HomeAccountName = ko.observable(game.HomeAccountName);
this.VisitingAccountName = ko.observable(game.VisitingAccountName);
this.GameDateString = ko.observable(game.GameDateString);
this.GameTimeString = ko.observable(game.GameTimeString);
this.AvailableSportTypes = ko.observableArray(game.Sports);
this.sportTypeFunction = function () {
for (sportType in this.AvailableSportTypes()) {
if (this.AvailableSportTypes()[sportType].Name == this.SportTypeName()) {
return this.AvailableSportTypes()[sportType];
}
}
return null;
};
this.SportType = ko.observable(game.SportType);
}
}
SportType is an object with Name and SportTypeId.
I have the following template:
<td rowspan="3"><select data-bind="options: AvailableSportTypes, value: SportType, optionsText:'Name', optionsCaption: 'Choose...'" class="sportType"></select></td>
AvailableSportTypes is a list of SportType.
The list is coming in with the names of the SportTypes in the drop down list, but I can't make the initial selection be SportType. I wrote sportTypeFunction to show myself that the data was coming in correctly, and it would select the correct value, but changing my selection in the drop down would not update SportType.
I'm sure I'm doing something wrong. Anyone see it?
Thanks
When game.SportType gets passed in, it needs to be a reference to the an item in the game.AvailableSportTypes and not just an object that looks the same.
Basically two objects are not equal unless they are actually a reference to the same object.
var a = { name: "test" },
b = { name: "test" };
alert(a === b); //false
So, you would need to call your function to locate the correct object in the array and set it as the value of your observable.
Not that it is way better, but in KO 1.3 you can extend .fn of observables, observableArrays, and dependentObservables to add additional functionality.
Here is a sample: http://jsfiddle.net/rniemeyer/ZP79w
I have a supposedly common problem to solve (done easily with other grid controls I'm familiar with).
In jqgrid, i'm quite stumped.
I have a jqgrid with inline editing enabled. I would like to add some scripting so that when editing a row (or adding a new row), the value of ColumnC is automatically computed as ColumnA * ColumnB as default. The user can change the values in any column at any time. I want this value to be computed as soon as the user enters it and not wait till the data is saved.
My approach so far has been to attach a dataEvent of type "change" to ColumnA and ColumnB -
dataEvents: [
{ type: 'change', fn: function(e) {
var rowid = $("#myGrid").jqGrid('getGridParam','selrow');
var rowData = $("#myGrid").getRowData(rowid);
var cell1 = rowData['ColumnA'];
var cell2 = rowData['ColumnB'];
var newValue = cell1 * cell2;
$("#myGrid").jqGrid('setCell', rowid, 'ColumnC', newValue);
}
},
]
Obviously, cell1 & cell2 don't actually return the value but the whole cell content as already discovered by other users here How to get a jqGrid cell value. The only way to get a cell value seems to be to use a custom regex user function that strips out that value.
Apart from that, is there a better/alternate way to achieve what I need? Something as simple as jqGrid - How to calculated column to jqgrid? though obviously that won't cut it for me since it will only displaying data and user cannot update it.
Any help would be appreciated.
UPDATE: After guidance from Oleg, I was able to extend getTextFromCell to support what I need.
function getTextFromCell(cellNode) {
var cellValue;
//check for all INPUT types
if (cellNode.childNodes[0].nodeName == "INPUT") {
//special case for handling checkbox
if (cellNode.childNodes[0].type == "checkbox") {
cellValue = cellNode.childNodes[0].checked.toString();
}
else {
//catch-all for all other inputs - text/integer/amount etc
cellValue = cellNode.childNodes[0].value;
}
}
//check for dropdown list
else if (cellNode.childNodes[0].nodeName == "SELECT") {
var newCell = $("select option:selected", cellNode);
cellValue = newCell[0].value;
}
return cellValue;
}
function getCellNodeFromRow(grid,rowId,cellName) {
var i = getColumnIndexByName(grid, cellName);
var cellValue;
//find the row first
$("tbody > tr.jqgrow", grid[0]).each(function() {
//The "Id" column in my grid is at index 2...
var idcell = $("td:nth-child(2)", this);
var currRowId = getTextFromCell(idcell[0])
if (currRowId == rowId) {
cellValue = getTextFromCell($("td:nth-child(" + (i + 1) + ")", this)[0]);
return false;
}
});
return cellValue;
}
The code in getCellNodeFromRow is not the most efficient. There is a .each() loop for find the matching row node. I can see this being slow when the grid has thousands of rows. Is there a better/more efficient way to find the row node? I have the row Id already.
Look at the demo from the answer. It uses cell editing, but the same technique work for inline editing too. Just click on any cell in the "Amount" column and modify the numerical value. You will see that the value in the "Total" row (footer) will be changed dynamically during the cell is still in the editing mode. I think it is what you need.
you can achieve this using onCellSelect event of jqgrid as below
//global section
var columnA;
var ColumnB;
var ColumnC;
var currentRow;
//
onCellSelect: function (rowid, iCol, aData) {
currentRow = rowid;
var ColumnA = $('#grid').getCell(rowid, 'MyCol');
var ColumnB = $('#grid').getCell(rowid, 'MyCol');
$("#grid").jqGrid('editRow', rowid, true );
$("#myMenu").hide();
if (rowid && rowid !== lastsel) {
if (lastsel) jQuery('#grid').jqGrid('restoreRow', lastsel);
$("#grid").jqGrid('editRow', rowid, true );
lastsel = rowid;
}
else if (rowid && rowid === lastsel)
{ $("#grid").jqGrid('editRow', rowid, true ); }
//if it is in editable mode
// when you view the html using firebug it will be like the cell id change to
//format like "rowid_ColumnName"
$('#' + currentRow + '_ColumnC').val(ColumnA*ColumnB);
// or you can use achieve this using following jqgrid method at
//appropriate place
$("#myGrid").jqGrid('setCell', rowid, 'ColumnC', ColumnA*ColumnB);
}
