I am trying to add rows to a grid using dhtmlx in java, following is the code.
var combinedColumn = "displayText";
displayOptionsGrid.addRow(selectedID, [ displayOptionsGrid.getRowsNum() == 0 ? 1 : 0, combinedColumn]);
What the function is supposed to do is that if the number of rows is zero it adds the first row as checked and then the rest as unchecked. The error which I am facing is, I delete the rows one by one and try to re-add the rows in the same session with some other row at first than the row I added previously, but can't. I can only add the row which I added first previously as the first row.
When I use grid.clearAll() it works fine. Can someone tell me the exact thing we do in clearAll() which we don't in deleteSelectedRows() in dhtmlxgrid. Thanks.
Please, check your selectedID attribute.
Note that each row should have a unique id, so adding a row with the id existing in your grid will break the grid.

I'm learning about Power Builder, and i don't know how to use these, (DWitemstatus, getnextmodified, modifiedcount, getitemstatus, NotModified!, DataModified!, New!, NewModified!)
please help me.
Thanks for read !
These relate to the status of rows in a datawindow. Generally the rows are retrieved from a database but this doesn't always have to be the case - data can be imported from a text file, XML, JSON, etc. as well.
DWItemstatus - these values are constants and describe how the data would be changed in the database.
Values are:
NotModified! - data unchanged since retrieved
DataModified! - data in one or more columns has changed
New! - row is new but no values have been assigned
NewModifed! - row is new and at least one value has been assigned to a column.
So in terms of SQL, a row which is not modified would not generate any SQL to the DBMS. A DataModified row would typically generate an UPDATE statement. New and NewModifed would typically generate INSERT statements.
GetNextModifed is a method to search a set of rows in a datawindow to find the modified rows within that set. The method takes a buffer parameter and a row parameter. The datawindow buffers are Primary!, Filter!, and Delete!. In general you would only look at the Primary buffer.
ModifedCount is a method to determine the number of rows which have been modifed in a datawindow. Note that deleting a row is not considered a modification. To find the number of rows deleted use the DeletedCount method.
GetItemStatus is a method to get the status of column within a row in a data set in a datawindow. It takes the parameters row, column (name or number), and DWBuffer.
So now an example of using this:
// loop through rows checking for changes
IF dw_dash.Modifiedcount() > 0 THEN
ll = dw_dash.GetNextModified(0,Primary!)
ldw = dw_dash
DO WHILE ll > 0
// watch value changed
IF ldw.GetItemStatus(ll,'watch',Primary!) = DataModified! THEN
event we_post_item(ll, 'watch', ldw)
END IF
// followup value changed
IF ldw.GetItemStatus(ll,'followupdate',Primary!) = DataModified! THEN
event we_post_item(ll, 'followupdate', ldw)
END IF
ll = ldw.GetNextModified(ll,Primary!)
LOOP
ldw.resetupdate() //reset the modifed flags
END IF
In this example we first check to see if any row in the datawindow has been modified. Then we get the first modified row and check if either the 'watch' or 'followupdate' columns were changed. If they were we trigger an event to do something. We then loop to the next modified row and so on. Finally we reset the modified flags so the row would now show as not being mofified.
When I spy the table it shows just browser - Page - WebElement and also UI is developed in Angular JS.
I there any way to find row number and column number? By the way I am using UFT/QTP
From the source-code's image which you have attached, it is quite evident that the webElement corresponding to the rows have class = "ui-grid-row ng-scope". So, you can make use of descriptive programming. I assume that you already have added the object Browser(...).Page(...) to your OR.
Set rowDesc = Description.Create
rowDesc("Class Name").value = "WebElement"
rowDesc("Class").value = "ui-grid-row ng-scope"
Set objRows = Browser(...).Page(...).ChildObjects(rowDesc)
rowCount = objRows.Count 'This variable should now contain the total number of rows"
Now, this is just an idea which you can give a try. If it works for you, you can further enhance it to get the column count. If there is no way you can get the column count, then you can get the total cell count using the same method. In that case, you just need to change the value of property "class" to the one mentioned in the Object Spy Image("ui-grid-cell-contents ng-binding ng-scope"). Now you have Row Count and Cell Count. To get the column count, you can divide cell count by row count.(Again, this will give you correct answer ONLY IF there are same number of columns for each of tbe rows).
I'm having trouble using XPath to find a row in a table where a specific column contains a value. The table has 10 columns where 2 of them will show Yes|No but I'm only interested in finding the value in one of the columns (the 4th one). My initial attempt was this:
//table[#id='myTable']/tbody/tr/td[text() = 'Yes']
but it finds it rows from both columns. I thought I could try something like this but it's not a valid expression:
//table[#id='myTable']/tbody/tr/td[4]/text()='Yes'
Any suggestions? Thanks.
You can try this way :
//table[#id='myTable']/tbody/tr[td[4][. = 'Yes']]
The XPath return row (tr) having the forth td child value equals "Yes".
I have an app with a KendoUI DropDownList that is populated with a list of tables from a database and a grid that is initially set with a columns atrribute of an empty array:
...
columns: []
...
The intent is to select a table from the list, send the table name to the server and have the server return JSON data containing the column names and the data from a "SELECT * FROM table" query. The data comes back as expected and the first time through I can use it as follows where "self" is just a reference to the grid in my view/model:
self.columns.removeAll();
for (var i = 0; i < joOutput["Cols"].length; i++) {
var col = { title: joOutput["Cols"][i], field: joOutput["Cols"][i] };
self.columns.push(col);
}
After extracting my data and assigning it to the grids datasource, the grid displays correctly with the correct column headers and data. However, when I select another table from the list and receive data from the server, the grid display does not update, even though it seems the grid columns have been updated though the execution of the above code. The end the result on screen is the column headers are the names of the columns from the first grid and the number of empty lines from the rows returned from the second query.
This dynamic manipulation of columns seems to be very difficult to do as seen by the forum post at http://www.kendoui.com/forums/ui/grid/dynamically-add-new-column.aspx but that post is over a year old now and I would've hoped some progress would've been made on this now, especially in light on the recent webcast on March 20 for the new release. So I guess the question remains: Is what I'm after even possible or am I SOL? Thanks.
You cannot dynamically change the columns of the grid after initialization. You can however create a new grid instance. Don't forget to call the destroy method of the old grid.
Greetings,
The context is myFaces 2.0.2, possibly also adding Tomahawk 20-1.1.10
I have created a dataTable (currently an h:dataTable, but could also be a t:dataTable using Tomahawk) displaying certain attibutes of a List<MyObject> in a backing bean. I have paging by returning only a subList of the List, and also sorting by click of column headers.
The next thing I need to do is ensure the table always shows a fixed number of rows. For example, if my page size is 5 and I have 12 items in the List, I need page three to show the last two items, plus 3 blank rows.
I have tried to "pad" the subList with both nulls and instances of myObject with null values, but this led to ConcurrentModificationException when hitting the last page of the table (the view was trying to getDisplayList even as the paging method was still adding the extra values.). I then tried padding the main list in the same manner, but then got NullPointers on my sort functions (a no-brainer in hind sight). Plus, these things are all addng overhead in the backer, when I would rather do this in the xhtml view.
(h:/t:)dataTable does have a rows attribute, but this specifies the maximum number of rows to display, not the minimum, as I need.
Ideas, please?
Don't pad the sublist. Pad the list. Preferably immediately after retrieving it in the bean.
The solution here was to pad the MAIN List, rather than the subList, using objects which are not null but whose attributes are null, and to add a null check into the Comparator:
if (obj1.getSomeValue() == null) {
return +1;
}
else if (obj2.getSomeValue() == null) {
return -1;
}
else {
// primary sorting code
}
Which ensures null items always come last. Works perfect.
BalusC did give me the push in the right direction, so I am accepting his answer.
