Windows API has 2 functions that returns time :
- GetLocalTime() returns the current local time.
- GetSystemTime() returns the UTC(GMT) time.

i am using windows aplliction using c#...

i have 1000 records in my table....
which has fields CUSTOMER_ID,NAME,CITY,SALARY.....

I HAVE TO SEE ONLY THE CUSTOMER WHO ARE LIVING THE CITY CALLED "DOWNTOWN"

HOW CAN I SEE THIS IN DATAGRIDVIEW...

PLS REPLY...
GIVE ME SUGGESTION OR SAMPLE CODING...

THNX IN ADVANCE

on load of the screen or where ever you are loading the grid
just before binding to the dataGrid you can loop through each row and check the condtion where Rows[0].Cells[0].tostring()=="xyz"

are you insane? I would hate to see crap like that in a program i have to maintain...

I have seen your answer ... but some times we can't hardcode any querry from sql command it will cost more if u need to change your condition.

anyway if you have ever used WCF then in services
we are binding the reader object with our business object for each row that time we can filter it out more easily...

In that case, create a stored procedure for SQL and call that in your application... problem solved Smile | :)

OR

Use the DataView object, i use this frequently to filter data dynamically

what if you dont have acess to the stored proc....??? Smile | :)

its written in COBOL and residing in Mainframe...

do you know ??????

a stored proc can be written in COBOL..

and sorry you can acess these stored proc using your ass..from C# also

Hi,

Why don't you use the BindingSource Filter property?

For example, you can have myDataSource.Filter = "City = 'DOWNTOWN'"

Here is the example from MSDN:

private void PopulateDataViewAndFilter() {
DataSet set1 = new DataSet();

// Some xml data to populate the DataSet with.
string musicXml =
"" +
"<music>" +
"<recording><artist>Coldplay<cd>X&Y" +
"<recording><artist>Dave Matthews<cd>Under the Table and Dreaming" +
"<recording><artist>Dave Matthews<cd>Live at Red Rocks" +
"<recording><artist>Natalie Merchant<cd>Tigerlily" +
"<recording><artist>U2<cd>How to Dismantle an Atomic Bomb" +
"";

// Read the xml.
StringReader reader = new StringReader(musicXml);
set1.ReadXml(reader);

// Get a DataView of the table contained in the dataset.
DataTableCollection tables = set1.Tables;
DataView view1 = new DataView(tables[0]);

// Create a DataGridView control and add it to the form.
DataGridView datagridview1 = new DataGridView();
datagridview1.AutoGenerateColumns = true;
this.Controls.Add(datagridview1);

// Create a BindingSource and set its DataSource property to
// the DataView.
BindingSource source1 = new BindingSource();
source1.DataSource = view1;

// Set the data source for the DataGridView.
datagridview1.DataSource = source1;

source1.Filter = "artist = 'Dave Matthews'";
}

Assuming the 1000 rows are coming from a data base, you have two options...

1) Query only the data your looking for and not everything, remember "any monkey can SELECT * FROM

2) Use a DataView to filter out the data you want to display

as mentioned use the filter option or change the query to have a where clause.
but FYI. THE USE OF CAPITALS is considered shouting in forums. Big Grin | :-D

DataGridView is populated with all coumns from database since i need some
column's data for condition statement (user will select columns at run time for display), so how to filter DataGridView column in order to
show whatever column user want?

-- Ravi Munde

Each DataGridViewColumn has a Visible property you can change so that you only display what you need.

Confused | :confused:

There are 5 Display Modes in WebParts.

DesignDisplayMode
BrowseDisplayMode
EditDisplayMode
CatalogeDisplayMode
ConnectDisplayMode

If you are in BrowseDisplayMode the you cannot move the webparts.

To move the parts you have to set it to either DesignDisplayMode or EditDisplayMode.

or If you never want the BrowseDisplayMode then add this code to your Page_Load() where wpManager is the name of your Web Parts Manager (WebPartManager1)

if(!Page.IsPostBack)
    wpManager.DisplayMode = WebPartManager.EditDisplayMode;

if (!wpManager.DisplayMode.AllowPageDesign)
    wpManager.DisplayMode = WebPartManager.EditDisplayMode;
