you could do something like the following in your clicked_handler.
it goes through all mdi childforms....if the one you are trying
to open is already opened, it activates the windows and returns.
if it's not found, it creates a new mdi childform.
<br />
foreach (Form f in this.MdiChildren)<br />
{<br />
if (f.Name.Equals("mySubForm"))<br />
{<br />
f.Activate();<br />
return;<br />
<br />
}<br />
}<br />
<br />
mySubFormn f= new mySubForm(this);<br />
f.MdiParent = this;<br />
f.Show();<br />

Hi All,
Is there any means to Generate an XML file by reading the XSD file. We need to use the Default values of each XSD element in the XML.
Thanks in advance.

please send me the reply of the question in subject, i.e. how to use stylesheet class for crystal reports in windows form in VS 2005.

Hi Imran,
Which version of Crystal Reports are you using? Is it the bundled version (version comes along with VS2005) or the full product?
You can apply a style sheet to a report object if you use Crystal Reports 9 or 10 Developer or Advanced edition.
However, you cannot apply a style sheet if you use Crystal Reports for Visual Studio .NET (CR for VS
.NET). This is an embedded version of Crystal Reports that is installed with Visual Studio .NET.
To apply a style sheet with Crystal Reports 9 or 10:
1. Right-click the report object (you want to apply a style sheet to) and select 'Format Field'.
2. On the 'Common' tab, type the style class name (defined in your style sheet) in the 'CSS Class Name' field.
I hope this helps.
3. Save and close the report.
4. Edit your HTML code to have your web page recognize the style sheet.
For example, if your style sheet is named 'Style.css', use the following HTML code:
<!-Start HTML code -->
<HEAD>
<TITLE>My Webpage</TITLE>
<link rel="stylesheet" type="text/css"
href="Styles.css">
</HEAD>
<!-- End HTML code -->
Additional Information
--------------------
CR for VS .NET cannot apply style sheets to report
objects because the 'CSS Class Name' field is not
available as a format option for a report object.
In addition, when you format a report object in CR for
VS .NET, a style class name (with the format details)
is randomly created. Since the class name is randomly
created, it cannot be added to a style sheet.
To use your own style class name in a style sheet,
upgrade to Crystal Reports 9 or 10 Developer or
Advanced Edition.

From last night I was at work until 03H30 this morning, due to, among other things, what I find a strange quirk in an unbound DataGridView. When I use a class derived from DataGridViewRow, and add two or more of these rows to the grid, without populating their cells (still creating them), all my custom properties are set to null from the second row onwards. It doesn't matter whether I populate the cells of the first row or not, it always survives, but for every subsequent row, if I don't populate at least one cell, it gets sanitised. Even if the first row has no populated cells, populating one cell on a subsequent row ensures its survival.
I will illustrate. I have numbered only the lines that are relevant. The grid does not allow additions, so there are only two rows.
1. In the current state, firstRow.RowName = "Row A" and lastRow.RowName = "Row B".
2. If I comment out line 4, firstRow.RowName = "Row A" and lastRow.RowName = {null}.
3. It doesn't seem to matter at all whether lines 1 and 2 are commented out or not.
note
public class NamedRow: DataGridViewRow
{
public NamedRow() {}
public NamedRow(string rowName):this()
{
this.RowName = rowName;
}
public string RowName { get; set; }
}
private void GridBadForm_Load(object sender, EventArgs e)
{
dgvLayout.Columns.Add("Column 1", "Column 1");
dgvLayout.Columns.Add("Column 2", "Column 2");
NamedRow namedRowA = new NamedRow("Row A");
namedRowA.CreateCells(dgvLayout);
NamedRow namedRowB = new NamedRow("Row B");
namedRowB.CreateCells(dgvLayout);
namedRowB.Cells[1].Value = "B Two";
dgvLayout.Rows.Clear();
dgvLayout.Rows.Add(namedRowA);
dgvLayout.Rows.Add(namedRowB);
NamedRow firstRow = (NamedRow)dgvLayout.Rows[0];
NamedRow lastRow = (NamedRow)dgvLayout.Rows[dgvLayout.Rows.Count - 1];
Debug.Print(firstRow.RowName);
Debug.Print(lastRow.RowName);
}

Hei
I´ve got a solution that works, not optimal, but it works
this.Left = 0;
//place our form at top
this.Top = 0;
this.WindowState = WindowState.Normal;
this.Height = SystemParameters.PrimaryScreenHeight - 30;
this.Width = SystemParameters.PrimaryScreenWidth;

Hi Sun,
In order to give some special effects or look and feel to existing .Net menus may require considerable amount of time and effors (coding).Therefore, it would be better if you to try any of the third party .Net visual developement tools. You may try ComponentOne Studio Enterprise for .Net. It is a complete package for all layes of Windows (WinFormApp, WebApp, and Mobile). For more details or to download the free trial of the package please visit.

I hope this helps .

I create and add a new row to an unbound DataGridView. Then, if I try and access an item in the Cells collection of the row, as in my commented out code, I get an index out of range exception, rowIndex. I’m not specifying a row index, so I assume it is inferring it from the row object, whose rowIndex property is -1. However, when I access the cell through a row in the grids Rows collection, I’m happy, as in my other code. Can anyone explain this behaviour?<o:p> <o:p>

I can not even see your code. Can you?

Something went badly wrong there. Here it is:
ExportLineRow newRow = new ExportLineRow();
newRow.ExportLine = newLIne;
newRow.CreateCells(dgvLayout);
dgvLayout.Rows.Add(newRow);
int cx = 1;
foreach (Column o in newRow.ExportLine.RecordLayout.Columns.Values)
{
int rowIndex = dgvLayout.Rows.Count - 1;
dgvLayout.Rows[rowIndex].Cells[cx].Value = o.ColumnValue;
cx++;
}
|
|
|
|
|
my guess is nothing is wrong with rowIndex, but cx exceeds the Cells array because it
started at 1. Catch the exception, look at the line numbers in it, and tell Visual Studio
to always show line numbers (menu Tools/Options/TextEditor/...) so see exactly what line is
failing.

cx starts at 1 because the is always a default column at the leftmost side of the grid. The line that is failing is:
newRow.Cells[cx].Value = o.ColumnValue;
I have checked and the number of columns is large enough. Using the same cx in the following line works fine.
dgvLayout.Rows[rowIndex].Cells[cx].Value = o.ColumnValue;

doesn't foreach (Column o in newRow.ExportLine.RecordLayout.Columns.Values)
iterate over ALL the columns, hence one more is bound to exceed the largest acceptable index?

Both cases, the one commented out that doesn't work, and the one not commented out, are inside the same foreach loop, so my column indexing is not the problem. In other words, this works:
foreach (Column o in newRow.ExportLine.RecordLayout.Columns.Values)
{
int rowIndex = dgvLayout.Rows.Count - 1;
dgvLayout.Rows[rowIndex].Cells[cx].Value = o.ColumnValue;
cx++;
}
while this doesn't work:
foreach (Column o in newRow.ExportLine.RecordLayout.Columns.Values)
{
DataGridViewCell c = newRow.Cells[cx];
newRow.Cells[cx].Value = o.ColumnValue;
cx++;
}
|
|
|
|

if a simple guess doesn't help, establish the facts:
what does "doesn't work" mean?
what is the exact exception?
it goes wrong in exactly which line?
what is the value of the bad index?
what are the acceptable values of the index?
is newRow.ExportLine.RecordLayout.Columns.Values.Count equal to newRow.Cells.Count? check it!

1, 2, & 3. It throws an exception on the line I highlighted in an earlier post on this thread:
newRow.Cells[cx].Value = o.ColumnValue;
Specified argument was out of the range of valid values.
Parameter name: <big>rowIndex</big>
cx = 1
newRow.Cells.Count = 14
newRow.IsNewRow = true [Maybe this is my problem]
QuickWatch: newRow {DataGridViewRow { Index=-1 }} LayoutEditor.ExportLineRow

Thanks Luc, you have really made an effort ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif) , but the problem is clearly with the rowIndex being -1. I have checked everything else down to the bone, just short of debugging...Oooh, I can step into the source now!  Now, where was that .NET source?
