Do you by any chance have a private field that looks like this?

private bool ShowThing = true;

hi ,
i have this problem,
i have a grid contains project combo box and projectStage combo,when i select the project from first combo it will filter the second combo values,
i got it but when i m selecting the project for the next row it filter all second combo values even in the first row, here is my code

private void FrmMain_Load(object sender, EventArgs e)
{
EMS.Timesheet timesheet = new WindowsApplication1.EMS.Timesheet();
dsInitialData = timesheet.GetInitialData(UserProfile.EmployeeId);

bscProject.DataSource = dsInitialData.Tables["Projects"];
dgvTimeAttProject.DataSource = bscProject;
dgvTimeAttProject.DisplayMember = "ProjectRef";
dgvTimeAttProject.ValueMember = "ProjectId";

bscStage.DataSource = dsInitialData.Tables["Stages"]; ;
//bscStage.Filter = "ProjectTypeId=-1";
dgvTimeAttStage.DataSource = bscStage;
dgvTimeAttStage.DisplayMember = "StageName";
dgvTimeAttStage.ValueMember = "ProjectStageId";
}

private void dgvTimeAtt_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
try
{
if (e.RowIndex == -1)
return;

if (dgvTimeAttProject.Index == e.ColumnIndex)
{
int ProjectId = (int)dgvTimeAtt.Rows[e.RowIndex].Cells[dgvTimeAttProject.Index].Value;
int projectTypeId = GetProjectType(ProjectId);
bscStage.Filter = "ProjectTypeId=" + projectTypeId.ToString();
bscActivity.Filter = "ProjectTypeId= " + projectTypeId.ToString();

//dgvTimeAttStage.DataSource = dsInitialData.Tables["Stages"].Select("ProjectTypeId=" + projectTypeId.ToString());
//dgvTimeAttActivity.DataSource = dsInitialData.Tables["Activities"].Select("ProjectTypeId= " + projectTypeId.ToString());
}
}

catch (Exception ex) { throw ex; }

}

so how can i overcome this problem?

i will ask it in other words,
if i have grid with tow DataGridViewComboBoxColumn first one for contries and second one for cities , when the user select a country the city combo will have the all cities in the country selected in first grid ,
i did it like that:

bscCountries.datasource=GetAllCountries();
dgvCol_Countries.DataSource =bscCountries;
dgvCol_Countries.DisplayMember ="Name";
dgvCol_Countries.ValueMember = "ID";

bscCities.datasource=GetAllCities);
dgvCol_Cities.DataSource =bscCities;
dgvCol_Cities.DisplayMember ="Name";
dgvCol_Cities.ValueMember = "ID";

private void dgvTimeAtt_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
bsc_Cities.filter="CountryId="+dgvCol_Countries.Rows[e.RowIndex].Cell[e.CellIndex].value;
}
that's work fine but , when i go to next row in the grid and select other country the selected city i choose is gone .
How can i fix it?

Need regular expression for spliting string

Hi friends,
I need to split the line which I am reading from a csv file using ,(comma). But I need to skip the commas which are coming inside quote.For example for line
1,12/12/2008,"This is test, test2"
The result should be

1<br />
12/12/2008<br />
"This is test, test2"

not like

1<br />
12/12/2008<br />
"This is test, <br />
test2"

Please guide me to do this with regular expression or by any other method.
Thanks in advance
Ramesh Ramalingam

Personally I'd iterate over each character in the string, adding it to a stringbuilder and outputting the result on a comma or end of line. Use a boolean toggle on double quotes to disable in quote commas.

You've not given enough information about the format of your string, so this regex will match the given string, but might not work on other strings:

(\d+),(\d+/\d+/\d+),(.+)

It should do exactly what you want. To see it work, run the demo app.

I didn't read it closely; does it support escaped quotes within quoted strings?

No, but you could always extract the quoted string as a field, and then create another parser instance and let fly.

string data = "my mother,the car,"other stuff,'my,other,stuff'",lastfield;
StringParser parser = new StringParser(data, ",", "\"");
string quotedField = parser.GetField(2);
StringParser parser2 = new StringParser(quotedField, ",", "\'");

This should match a CSV line with one or more values, inluding quoted values containing commas and encoded quotes:

("(?:[^"]|"")*"|[^,\r\n])(?:,("(?:[^"]|"")*"|[^,\r\n]))*

(No guarantees, not tested.)

That should be handled. [^"] matches any character except a quotation mark, so that includes newline characters aslo.

Use Split if you need to get all the words in an array. If it is some specific word or phrase, use Regex as replied earlier.

C isn't that hard: void (*(*f[])())() defines f as an array of unspecified size, of pointers to functions that return pointers to functions that return void
