EPM Formatting Sheet Issue - Right click on the cell and lock the cell
Dear Experts,
I have come across an issue. Earlier I worked on BPC NW 10 integrated with Ms Excel 2007. I applied a feature of locking the cell linked with specific member in Input Template and Report by going to EPM Formatting Sheet, selecting dimension member (Which I want to lock in Input Sheet and Report), right clicking on the cell under Data Column and selecting the option "Lock the Cell". As I protect my Input sheet and Report, and do refresh, the cell linked with specific dimension member get locked. Hope everyone has used this feature.
Now I have Ms Excel 2013 installed in system. I am not able to find this feature. if anyone has tried this feature in BPC NW 10 with Ms Excel 2013. Please help me out. As this was good feature by BPC.
Regards,
DavidHi Andy,
I am using Excel 2013, When I checked, I did not find "Lock Option". When I was using Excel 2007, then I had this locking option. below are the details that you asked for...
When I right click on cell in EPM formatting sheet, I get options as shown below in screen shot, but there is no "Lock Option"

Rules applied to multiple cells trigger color changes when any of the cells
"Rules applied to multiple cells trigger color changes when any of the cells meet the rule’s condition." That's what Help says, but when I follow the directions, it doesn't work. This is in Numbers 08.
I have a table where the contents of one column are either "YES" or "NO", depending on formulas using variables from other cells. If YES, I want the fill of that cell and that of two adjacent cells to change from white to green. I select all three cells and use conditional format rules for "text contains:" YES, then choose my fill color. When I return to the table and introduce values for the variables that trigger the rule, only the cell in the YES/NO column changes to green; the other two remain white.
While I am spreadsheet challenged, I usually can follow directions as plain as those in Help, but it's not working. I couldn't find anything in the discussions after an hour of searching. Is this a known problem or am I just stupid?For what it's worth, that's the way I read that line in the User Guide as well. What it actually appears to mean, though is 'Rules applied to multiple cells apply independently to each of the cells."
Here's a workaround for your three adjacent columns. Long, but fairly simple steps.
Add a second table to the sheet (Table 2).
Resize the second table to one column wide and as many rows as you want to apply the conditional format to.
Set the width of the column to the same width as the three columns you want to highlight, and the row height(s) to match the rows.
Format to table to have NO Header or Footer row or column.
Use the Wrap Inspector to uncheck "Object causes wrap"
In the first top cell of Table 2, enter an = sign, then Click on Table 1 in the sidebar, Click on the first cell that will hold YES or NO.
Fill the formula down the rest of Table 2.
With all cells in Table 2 selected, use the Cell Format inspector to set the 'text contains yes' rule and the conditional fill colour for these cells.
Test the conditional formating by introducing values into Table 1.
Click on Table 1 in the sidebar, then use the Table inspector to set Cell Fill to 'none'.
Click on Table 2 in the sidebar, then drag that table onto table 1 aligning it to cover the cells in which the conditional formating is to appear.
When positioned (and still selected), go to the Arrange menu and Send Backward to move Table 2 behind the (transparent) cells in Table 1.
With Table 2 still selected, click on the Cell Borders color well and set the Opacity of the borders to 0%.
Click the Text inspector and set the Text colour Opacity for Table 2 to 0%.

Capture single click in a cell in JTable
I have a Table which has a column that needs to act like a URL link. I.e. when clicked it will bring up a web page. How can I get the mouse event when a specific cell is clicked as well as what cell was clicked?
The table can not be editable as well as only row selection can be allowed. The user can select rows (not cells), but needs to be able to click a certain column to fire an event?
ThanksTo make your table read-only, simply assign it a TableModel which has the method:
public boolean isCellEditable( int row, int col ){
return false;
}To get cell co-ordinates from a mouse click, in your MouseListener class, just do this:
public void mouseClicked( MouseEvent e ){
Point p = e.getPoint();
int row = myJTable.rowAtPoint( p );
int col = myJTable.columnAtPoint( p );

Data is not being displayed into DataGridview until Clicked inside the cells
Hi,
On a windows form, I have a DataGridView, its columns are auto-generated every time. Data is loaded after the user click a data-load button. However this is NOT working well, the data is not displayed until manually clicked inside the grid cells. The following
is the code. Could you please help? Thanks!
private void ButtonTestGrid_Click(object sender, EventArgs e)
for (int i = 0; i < 10; i++)
this.MainDataGrid.Columns.Add(TestHelper.CreateTextBoxColumn("Col" + i.ToString(), 120));
Dictionary<string, object>[] data;
data = TestHelper.CreateTestData();
this.MainDataGrid.EndEdit();
TestHelper.LoadGridData(this.MainDataGrid, data);
this.MainDataGrid.Refresh();
public class TestHelper
public static DataGridViewTextBoxColumn CreateTextBoxColumn(string name, int width)
DataGridViewTextBoxColumn column = new DataGridViewTextBoxColumn();
column.HeaderText = name;
column.Name = name;
column.ReadOnly = false;
column.Width = width;
return column;
public static void LoadGridData(System.Windows.Forms.DataGridView grid, Dictionary<string, object>[] data)
int index;
foreach (Dictionary<string, object> row in data)
index = grid.Rows.Add();
LoadRowData(grid, index, row);
public static void LoadRowData(System.Windows.Forms.DataGridView grid, int index, Dictionary<string, object> data)
string name;
for (int i = 0; i < grid.Columns.Count; i++)
name = grid.Columns[i].Name;
if (data.ContainsKey(name))
grid.Rows[index].Cells[name].Value = data[name];
public static Dictionary<string, object>[] CreateTestData()
Dictionary<string, object>[] dataList = new Dictionary<string, object>[5];
Dictionary<string, object> data;
for (int j = 0; j < 5; j++)
data = new Dictionary<string, object>();
for (int i = 0; i < 10; i++)
data.Add("Col" + i.ToString(), i);
dataList[j] = data;
return dataList;There are different ways to bind the datagridview control to it's datasource, the question is where and what is your datasource? Is it from a database or XML file, or is it built on runtime...etc?
Based on your explanation I can understand that the Datagridview is binding correctly in the code behind since the rows of the grid are created. Because the row of the Datagridview are created only while it is binded correctly to it's datasource. The issue
of the display seems something different and strange.
Try also this way by using DataTable one the common ways used:
static DataTable GetTable()
// Here we create a DataTable with four columns.
DataTable table = new DataTable();
table.Columns.Add("Dosage", typeof(int));
table.Columns.Add("Drug", typeof(string));
table.Columns.Add("Patient", typeof(string));
table.Columns.Add("Date", typeof(DateTime));
// Here we add five DataRows.
table.Rows.Add(25, "Indocin", "David", DateTime.Now);
table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
return table;
Then to bind the above Datatable to the grid control:
this.MainGrid.DataSource = null;//To clear before bind
this.MainGrid.DataSource = GetTable();

When I single click on a weblink (usually in an email, Firefox starts up and opens two windows; one with the selected web page and one with my home page. If Firefox is running, it opens a new tab which is what normally occurs. It is only when it is not open that I now get the 2 windows. I have an imac running OSX 10.6.3
== This happened ==
Every time Firefox opened
== In the past couple of weeks.Hi,
The rolling over from radius servers only occurs on the same wlan and only when the controller deems the radius server being dead. However, if you get rejected from one WLAN but then you reassociate to another WLAN there is no mechanism in place in rejecting the attempt because they previously failed on a seperate wlan. This happens all the time with users connecting on incorrect wlans.
The failover feature is for when you have multiple servers (usually for redundancy) on the same WLAN. So when user is rejected but radius server 1 the process stops there and the request isnt sent to radius server 2.
Hope that helps!

SharePoint Edit form should pop up when clicked on the hyperlinked itme of a SharePoint list
I have a SharePoint list where i hae this title column which when clicked brings the display form.
Can i modify it in such a way that it should pop up the edit form in place of dislay form.
ThanksOpen the AllItems.aspx page of that list in SharePoint Designer
Select a title and right click on it. Format item As -> Hyperlink to -> Edit Form
This will redirect you to edit form when the title column link is clicked.
But if you want to show the modal pop up it edit mode, open the Allitems.aspx page in designer
Select the list view web part, on the ribbon in the List View Tools -> Design tab -> Customize XSLT -> Customize Entire View
Switch to the code view, search for FORM_DISPLAY and change it to FORM_EDIT.

How to retrieve Data in a JTable, When you click on the specified line?
I Have a JTable. When I click on a line, I want to retrieve the value of the last column of the selected line.
I do that:
int selectedRow = lsm.getMinSelectionIndex();
int selecRow = lsm.getMaxSelectionIndex();
String res="";
if (selectedRow == selecRow)
System.out.println("number of colomns="+nbCol);
indiceDoc=(String)(data[selectedRow][1]);
res = " Row "+selectedRow + " selected"+"Indice =:"+indiceDoc;
else res = " Rows "+selectedRow + " to "+selecRow + " selected";
When the table is not sorted, it's ok, but when I sort one or more colomns, it don't return the correct value. It returns the value of an other line.
"Data" is my original table, but I think that it don't change when sorting.There is the Problem I thinK.
I think its because the index of the lines is reinitialize after each sorting.
Do you have an Idea?The problem seems to be the sorter. You will have to ask the sorter for the sorted row number.
I have modified my TableSorter with a new method:
public int getJTableRowToModelRow(int index) {
return indexes[index];
So in my class which holds the tablemodel, table & sorter if I want to get hold of an row I write:
int selectedRow = table.getSelectedRow();
int sorterRow = sorter.getJTableRowToModelRow(selectedRow);
Object data = tableModel.getData(sorterRow);
tableModel.getData(int row) is an added method to the tablemodel. It only, in your case, returns data[row][1];
I hope this wasn't to messy for you... ;-)

Unable to add a printer. When I click on the "Add Printer" button, nothing happens.
I have IE9 on Windows 7 PC. I have compared my Internet options with another PC and it does not seem to have this issue. Any suggestions?
NOTE: Please don't suggest changing browsers. That is a work-around not a solution.
ThanksHi,
Clicking the Add a Printer actually not much related with any web browser but more with the operating system functionaity.
I would suggest you to try updating windows by running Windows Update, reboot the PC and check for any change.
Also make sure the Print Spooler Service is running:
Click the Start button and typr run into the search box.
Open the Run Application within the results.
Type net start spooler, then click OK
You should see a black dialog for a single moment.
Next go to Control Panel > Devices and Printers and try adding a printer again,
If the option still not function I would recommend you to contact Microsoft support as the problem relies within the operating system and not within the HP software.

Normally I get the stars but not now. Can someone tell me what's going on and what I have to do to make rating a song work? Thank you!

Re- Single click in the check box ensure to select all check boxes
Hi All,
I have an issue to notify the urgency of the cart to the buyer while creating the cart.For that scenario we have a check box in the Basic data of shopping cart.I added the check box in the basic data. Now the quote check box is available for all the line items.
The requestor can select any check box in any line items,so whenever he selects the check box- automatically all the check box should get selected , if any of the check box get deselected then imediatelely all the check box in different line items also should get deselected.Hi Batchu,
Thanks for your reply, See if you add any custom field it will come one by one in the basic data section. Adding one more check box doesnot work for this case.
Moreover the problem is change to any particular line item can be captured in DOC_CHANGE_BADI but i cannot bring the same change to all line items (ie) If 3 rd line item check box is marked then immediately rest of the line item also should get marked.
In the case of DOC_CHECK_BADI to identify the line on which the change happens is tough.
SO thats is the problem for me to bring the logic in the code.
Please if any one come across similar kind of issue please give your suggestion.
Thanks,
