Delete column in a datagrid

Hi All,
I was trying to delete a column in the data grid .
Explanation : The data grid has 16 columns filled with data
, when a specific column is selected and the "delete button(this
button is under the datagrid) is clicked I should be able to delete
the column , and the subsequent columns should move to the left
(for example : if I select column 7 and click delete button ,
column 7 should be deleted and column 8 should move left in place
of the column 7).
Can anybody please help me on this issue.
thanks

I think you'd have to loop through the array collection and
remove that
property off all the objects, assuming it's a dynamic object.

Formatting a column in a datagrid

If I want to format some data in a column of a datagrid is
there a preferred way of doing that? I have used both an
itemRenderer and a labelFunction
Is there a preference to one or the other?

lableFunction can be used when the tweaking required is very
trivial and you want to modify some text getting displayed.
(custom) itemRenderers can be used when we want to display
something complex within a cell like few controls, icons, labels,
links etc.

Remove Enable, Disable and Delete columns from searchUser.do

Hello,
What jsp form do I need to modify to remove the enable, disable and delete columns from the searchUser.do page? I edited tjspSearchUserResultsTiles.jsp but that didn't seem to do it.
Thanks

Hi,
TableGenerator.jsp is the general jsp so you shouldn't modify it.You need to extend tcSearchUserAction.java class aand create a custom class.You need to over ride populateColumnHeadings and populateTableData.
I won't suggest this approach until you are very much familiar with struts development and oim classes.

Locking middle or last column in a datagrid

Does anyone know how to lock say the middle or last column in
a datagrid. What i really need is for the first and fifth column to
be locked in a datagrid or Advanced datagrid. Is this possible or
do i need to put two datagrids next to each other and try to sync
the vertical scroll??
Thanks,
-Jay

>>For this, I have read that I can use Width="Auto" in all the columns and in the last column width="*", but in this case all the coloumns has a very low width so I can't read anything.
Can't you just set an explicit width for the first two columns then?, e.g.:
<DataGrid.Columns>
<DataGridTextColumn Header="Column01" Binding="{Binding Property1, Mode=OneWay}" Width="100"/>
<DataGridTextColumn Header="Column02" Binding="{Binding Property2, Mode=OneWay}" Width="100"/>
<DataGridTextColumn Header="Column03" Binding="{Binding Property3, Mode=OneWay}" Width=""*"/>
</DataGrid.Columns>
There is also a MinWidth property that you can use to prevent the columns from being to narrow:
<DataGrid.Columns>
<DataGridTextColumn Header="Column01" Binding="{Binding Property1, Mode=OneWay}" Width="Auto" MinWidth="100"/>
<DataGridTextColumn Header="Column02" Binding="{Binding Property2, Mode=OneWay}" Width="Auto" MinWidth="100"/>
<DataGridTextColumn Header="Column03" Binding="{Binding Property3, Mode=OneWay}" Width=""*"/>
</DataGrid.Columns>
Hope that helps.

WebService get list 750 records with 8 columns in mx:DataGrid atleast 2 minutes

I am using WebService (ASP.NET) to get a list of customers (around 750) records with 8 columns using mx:DataGrid. It takes to list data in the mx grid atleast 2 minutes from offline development data server[SQL SERVER 2005]. It could be better if the list populate the datagrid with-in 1 minute. I didn't find how to resolve the problem. My WebService returns the ArrayCollection within 1 minute.
Any hints would appreciate!
T. Ghosh

It doesn’t matter how many records, what matters is how many attributes and sub-objects. One customer returned 100 records, each with a transaction history of some 10,000 transactions, although the transactions were not displayed in the datagrid (it would be later in the detail view). Then the app was configured to convert the records to typed objects. As one would expect, it took forever. You might have to create a custom converter or just use the SOAP/XML.

Retain field order on form when adding/deleting columns

If I move my html around to change the layout of the fields on an AddForm.aspx and then I start adding and deleting columns, the ordering of the ff## changes and I can have problems.
Its fine if I've only added new columns...what I've done is create an AddForm1.aspx to get the fresh ff##'s at the end of the list. I copy them over to my AddForm.aspx
If I add and delete columns, then I can have problems.
The ff## may be renumbered when making an AddForm1.aspx and copying the new fields might create an error because of dupe ff##'s.
If I use AddForm1.aspx, I lose my layout of the fields on my form AddForm.aspx.
I have been successful finding the ordering of the columns on AddForm1 and renumbering on AddForm.
But this is pain and error-prone.
What do people do to get around this dilema?
thx
Rich

Hi,
By default, we can change the order at the Lists content type settings page.
I suggest you provide more information about your requirement(screenshot) to make others easier to find a solution for you.

RVR,
This is a great exercise to get familiar with LabVIEW's array functions. A great place to start is actually the LabVIEW help on arrays, located here:
http://zone.ni.com/reference/en-XX/help/371361B-01/lvconcepts/grouping_data_with/
Depending on your data format, you can probably use the Read From Spreadsheet File VI to bring your data into a 2-d array. You could then use the index array VI to pull your column out. You could do this in a For loop and use Autoindexing to build your 1,000 column resulting array. I would leave everything as a String format until I'm done.
This doesn't sound like a very difficult task. Good luck!

Referencing custom filled column (labelFunction) in datagrid

I got a column in a datagrid which is filled with data using some calculations done in a labelFunction.
now i got a second column, which need the data of the previous mentioned column.
normally you would type: item.Data or something, but that does not work for the calculated field.
how would i reference the first mentioned column in the labelFunction of the second?
thnx

The cheap way is to reference the the other column's labelFunction and call
it again. It means that the labelFunction will be called twice per row.
You can get to the columns via DataGrid(owner).columns[]
Another possibility is to add the labelFunction to the data objects or a
subclass of the data objects.

Ok... but I am a little confused (sorry to be a nuisance ),
my delete function within my webService requires an ID to be
passed from the Flex application, thus when a row is selected, the
ID of the selected row is taken, so when the Delete button is
pressed it sends this ID to the webService where it is taken and
used - and therefore deleting the row etc.....
Do you mean to define the result handler for the deleteOPG
operation in the main webService tag, i.e. :
<mx:WebService id="wsData" wsdl=http://...?wsdl>
<mx:operation name="getRes" result="handleWSR(event)"/>
<mx:operation name="deleteOPG"
result="handleWSR_deleteOPG(event)"/>
</mx:WebService>
and then call it in my delete function, passing the ID from
my delete function to my new result handler function ??? :
Thanks,
Jon.

Select column in Flash datagrid?

When someone is using a datagrid, is there a default way (not involving extra coding) to select just one entire column?
Currently when I click the header, it changes the order. Is there a Ctrl key + click combo that does this?
Cheers

Gidday kGlad, and thanks mate.
You know how Ctrl-A selects the WHOLE grid? I was wondering if there's something like that that selects all the rows in just one column. So for example, when editing a grid, you could select and delete all the data from one column.

How do I delete multiple rows from datagrid?

Hi,
I have a datagrid which has an item renderer on the 1st column which displays a checkbox. I wish to delete all the rows of data from my datagrid which have the checkbox selected.
I'd be very grateful if anyone can anyone help me with this.
Thanks in advance,
Xander

Working in MUD: after deleting column whole table gets lost

Good morning community,
we do have a problem with the obiee admin tool.
we just migrated to version 11.1.1.6.6.
Now a colleague of mine worked with the MUD. He checked out the RPD-file and wanted to delete a column from a table within the presentation layer. Then he checked in this change again. He Uploaded the file to the server and everything is working fine.
Now the problem:
When he checked it out again, he saw that the full table was "deleted", but not only in the presentation layer, also in the business modell and the physical layer.
He opened the RPD file locally and there everything was okay.
Our first idea that the admin tool lost the link of these tables to the project couldn't be confirmed.
So we are asking you :-)
Maybe someone of you had this problem too and can explain how he solved it.
Thank you and have nice day,
Sven

Hi Sven,
Then he checked in this change again. He Uploaded the file to the server and everything is working fine.It should not be the case please confirm below
1. Uploaded means ? directly moved to MUD server instead of doing checking or from MUD to system where BI installed (NQSconfig.ini) ?
2. I'm sure he deleted the table instead of column (track it from MUD History in file option -->)
3. Link will break when (Tables in BMM & Physical ) a fact table is deleted so automatically associated dims will go off
4. Get the latest version . XXX (from MUD server) then change it to .rpd and deploy to get rid of issue
thanks,
Saichand

How to delete columns from a 2D array

Hi guys,
I read a matrix from a text file and I want to delete the first and last columns of the matrix. I've been trying to do it with delete from an array function but it doesn't do it the way I want. Any suggestions?

Keep in mind that by default, 2-D LabVIEW arrays are row-based. So though you might be thinking that the first indexing input for the 'index array' primitive is for columns, it is actually for rows. You can either select the second input for the 'index array', or, if you are like me and think better in columns, you can transpose the array before you operate on it. I recommend getting used to the order of the inputs for the array tools and forcing yourself into the LabVIEW convention, as it gets complicated if you need to invert an array before you operate on it, and then again after so that the array returns to row-centric order, which is what all the rest of the LV array tools are expecting
Good luck!
