How to add delete button for ocmponents in TileList

I have a TileList that received text components. I would like to add a button that when clicked, removes the text item and renumbers the items.
How would I do this and where would I inject the command?
Code below:
    <mx:TileList width="320" height="100%" id="ImgList" dataProvider="{snapArray}" columnCount="1"
                  rowHeight="150"
                  cornerRadius="5" borderStyle="solid"
                  paddingLeft="2" paddingTop="2" paddingRight="2" paddingBottom="2"
                   backgroundColor="#EEEEEE">
            <mx:itemRenderer>
                <mx:Component>
                                    <mx:HBox verticalAlign="middle" horizontalGap="5" cornerRadius="5" borderStyle="solid"
                                        paddingLeft="2" paddingRight="2" paddingTop="2"
                                        width = "100%"
                                        height= "100%"
                                        >
                                        <mx:Image width="150" height="100%" source="{data.image}"/>
                                        <mx:VBox width="100%" height="100%" verticalAlign="middle">

In table view, how to add one button for selecting page?

Hi Experts,
In the OBIEE 11.1.1.6, we have one uncommon requirement that customers want to randomly select actual page to view expected data in table view.
For example:
We make use of some columns to create one report in table view, and set 'Rows per Page' equal to '5',
if this report contains 60 rows, it will have 12 pages, so customers want to select sepcial page number to view the some data. Is it possible to implement this requirement? Maybe we should write JS code.
Note: Below table view, it has four buttons: First Row, Previous Row, Next Row and Display (500) rows in per page. So we want to add one button to select per page.
We look at orgnial codes in WebBrowse, but do not know the following codes derive from which JS file.
Could you please tell me how to find this file?
<td class="TapeDeckCell"><img class="TapeDeckImage" onclick="" onkeypress="" src="res/s_blafp/viewui/pivot/first_dis.png" title="" alt="" ><img class="TapeDeckImage" onclick="" onkeypress="" src="res/s_blafp/viewui/pivot/previous_dis.png" title="" alt="" ><img class="TapeDeckImageEna" onclick="PTRowScroll('saw_5083_b','5','5', event)" onkeypress="PTRowScroll('saw_5083_b','5','5', event)" src="res/s_blafp/viewui/pivot/next_ena.png" tabIndex="0" onmouseover="PTTD(event, 'res/s_blafp/viewui/pivot/next_ovr.png');" onmouseout="PTTDO(event)" onmousedown="PTTD(event, 'res/s_blafp/viewui/pivot/next_dwn.png');" title="Next 5 Rows" alt="Next 5 Rows" ><img class="TapeDeckImageEna" onclick="*PTRowScroll*('saw_5083_b','-1)', event)" onkeypress="PTRowScroll('saw_5083_b','-1)', event)" src="res/s_blafp/viewui/pivot/showallrows_ena.png" tabIndex="0" onmouseover="PTTD(event, 'res/s_blafp/viewui/pivot/showallrows_ovr.png');" onmouseout="PTTDO(event)" onmousedown="PTTD(event, 'res/s_blafp/viewui/pivot/showallrows_dwn.png');" title="Display maximum (500) rows per page" alt="Display maximum (500) rows per page" > <Span class="TapeDeckRecords">Rows 1 - 5</Span></td>

Hi Kobe,
Thanks for listening me.
I agree 11g have some issues unlike 10g. I've tried the same by creating a measure rcount(1) and name it as Page in RPD. I just pulled column Page in pivot table section 'Pivot Table Prompts' it is working but this may not answer your requirements.
I would suggest to use the column in Prompt and go by between operator to allow user to select the rows between.
In the report make Page as prompted.
If you are okay with this can look forward to tweak it further, like values in the prompt multiple of 5 or 10s some thing like that.
let me know updates on the same.

How to add bookmark button for user to access application

I would like to add a button that will be an 'ADD BOOKMARK' concept for the user so that they don't try to save the url that is generated at the time they run the application.
I am using Apex 4.0.
Is anyone familiar with this concept?
I see it a lot on the internet with other websites.
Thanks,
Maggie

This post is made for the future Apex users that need this info.
I discovered a fantastic website that helped me generate the code needed for my apex page to add a bookmark link. This website is:
http://www.webmaster-affiliates.net/bookmark-site_doit.php
This was my code used (be sure to replace the curly brackets with a pointed less than/greater than bracket):
{div align=right}{a href="javascript:window.external.AddFavorite('http://your.url.goes.here:7780/pls/apex/f?p=Graphics_Status', 'Graphics Status')"}Bookmark Site{a}{div}
I created a page region and put the above code in the source field. Worked fantastic.

How to hide/remove the 'Delete' button for a particular role

We have a role that can only Create and Edit the Accounts, Contacts, Opportunities, & Leads. So I modified the Default and Owner Access Profiles for that role and changed the Access Level to 'Read/Edit' for each of the above mentioned Record Types.
When the user is logged with this role they can see the 'Delete' button on all the Record Types. When they click on the 'Delete' button they get the 'Access Denied' message. Thats fine, but how do you hide/remove the 'Delete' button for this role so they don't try to click it.

At this time it is not possible to hide/remove the "Delete" button. This functionality is on the roadmap.

HOW TO: Add /manipulate columns for a GridControl

HOW TO: Add /manipulate columns for a GridControl when the columns (attributes) are from different entity objects.
This HOWTO describes the basic steps of using attributes from different entity objects for a GridControl.
One way you can create a GridControl which contain attributes from different entity objects is to create a view object and base it on the entity objects which contain
the desired attributes.
Here are the basic steps:
1.Create a new view object (or use an existing view object) by selecting File>New from the menu, clicking the Business Components tab and double-clicking
on the View Object icon.
2.In the View Object wizard change the name to something meaningful.
3.Select the entity objects you will base your view object on.
4.Nivigate to the attribute screen and select the attributes you would like to include in your view object from each entity object. At this point you can also create
a new attribute by clicking the "New" button. The new attribute can be a concatenation of other attributes, derived from a calculation etc.
5.In the query panel of the View Object wizard, click "Expert mode" and enter a query statement. You write complex queries such as decoding a set of attribute
values.
6.Add your newly to your newly created view object to the application module by double-clicking on the application module in the navigation pane and selecting
your view object from the list.
7.Create a new row set.
8.Bind row set to a query by editing their queryinfo property and selecting your view object and its attributes from the queryInfo pane.
9.Create a GridControl and bind it to the row set by editing the dataItemName property of the GridControl. Since the GridControl is bound at the row set level
all of the related attributes are automatically added.

Michael,
Are you intending this as a commercial solution or a work around?
To take an existing equivalent, one would build a view in the database tailored for each grid in an Oracle Forms application. Or a separate query layered over tables for each form/grid in a Delphi or Access application? Even if it is ninety nine percent the same over half a dozen forms/grids?
And now you've added a whole slew of "slightly different" rowSetInfos to maintain.
So if you wanted to add a column that needs to appear everywhere... you've just increased the workload multi-fold?
That would be a management nightmare, wouldn't it? Not to mention yet more performance cost and a slower system?
Hmmmm..... I'm not sure I like where this is headed... someone needs to do some convincing...

How to add multiple button/choices in button choice

HI all ,
How to add multiple button/choices in button choice ?

Initialize a cluster array (CrsrList type) with as many cursors as you think you would ever need. Setup your cursors dynamically, then delete the unused cursors (array elements) and then update your CursorList property.

How to add linked button in grid?

Hi,
Does anyone know how to add linked button in a grid? I can't find it but i saw someone ask similar question but seems none of them works.
Thanks a lot!
P.S. For some reason, i can't use matrix because the data is from a SQL query.
Lan

Hi,
as far as I know it is not possible, since this adjustment is made for the whole column. I have created a grid and I open the shown document by double clicking the row header. In the grid I can see if it is sales or purchase and so I use a workaround by opening the specific system form (e.g. sales invoice) in find mode and search the document by document number (also shown in the grid).
Sample:
oSBOapp.ActivateMenuItem("2053"); //sales invoice
oForm = oSBOapp.Forms.ActiveForm;
oForm.Mode = SAPbouiCOM.BoFormMode.fm_FIND_MODE;
oEdit = (SAPbouiCOM.EditText)oForm.Items.Item("8").Specific;
oEdit.Value = Convert.ToString(dNum);
oForm.Items.Item("1").Click(SAPbouiCOM.BoCellClickType.ct_Regular);
By the click event, you get the specific row number. Hope it helps...
Regards
Sebastian

How to Add Push Button On Selection Screen

Hi Experts,
How to add Push button on Selection Screen.
Points will b rewarded for useful help.
Bohra.

Hi,
To create a pushbutton on the selection screen, you use:
SELECTION SCREEN PUSHBUTTON [/]<pos(len)> <push>
USER-COMMAND <ucom> [MODIF ID <key>].
The [/]<pos(len)> parameters and the MODIF IF addition have the same function as for the formatting options for underlines and comments.
<push> determines the pushbutton text. For <push>, you can specify a text symbol or a field name with a maximum length of eight characters. This character field must not be declared with the DATA statement, but is generated automatically with length <len>. The field must be filled before the selection screen is called.
For <ucom>, you must specify a code of up to four characters. When the user clicks the pushbutton on the selection screen, <ucom> is entered in the UCOMM of the SSCRFIELDS interface work area. You must use the TABLES statement to declare the SSCRFIELDS structure. The contents of the SSCRFIELDS-UCOMM field can be processed during the AT SELECTION-SCREENevent.
Ex.
REPORT DEMO.
TABLES SSCRFIELDS.
DATA FLAG.
SELECTION-SCREEN:
BEGIN OF SCREEN 500 AS WINDOW TITLE TIT,
BEGIN OF LINE,
PUSHBUTTON 2(10) BUT1 USER-COMMAND CLI1,
PUSHBUTTON 12(10) TEXT-020 USER-COMMAND CLI2,
END OF LINE,
BEGIN OF LINE,
PUSHBUTTON 2(10) BUT3 USER-COMMAND CLI3,
PUSHBUTTON 12(10) TEXT-040 USER-COMMAND CLI4,
END OF LINE,
END OF SCREEN 500.
AT SELECTION-SCREEN.
CASE SSCRFIELDS.
WHEN 'CLI1'.
FLAG = '1'.
WHEN 'CLI2'.
FLAG = '2'.
WHEN 'CLI3'.
FLAG = '3'.
WHEN 'CLI4'.
FLAG = '4'.
ENDCASE.
START-OF-SELECTION.
TIT = 'Four Buttons'.
BUT1 = 'Button 1'.
BUT3 = 'Button 3'.
CALL SELECTION-SCREEN 500 STARTING AT 10 10.
CASE FLAG.
WHEN '1'.
WRITE / 'Button 1 was clicked'.
WHEN '2'.
WRITE / 'Button 2 was clicked'.
WHEN '3'.
WRITE / 'Button 3 was clicked'.
WHEN '4'.
WRITE / 'Button 4 was clicked'.
WHEN OTHERS.
WRITE / 'No Button was clicked'.
ENDCASE.
This example defines four pushbuttons on a selection screen that is displayed as a
dialog box. The selection screen is defined in a statement chain for keyword
SELECTION-SCREEN.
If the text symbols TEXT-020 and TEXT-040 are defined as 'Button 2' and 'Button 4',
the four pushbuttons appear as follows on the selection screen displayed as a dialog box.
