As before. Ask on the site of the maker of the control.

Good morning.
I have populated a DataGridView with a dataset from a query off a table in SQL Server 2005. Now when a user makes changes in the DataGridView and clicks on a 'Save' button, I want the dataset to be updated and the table to reflect the changes. The datagrid is on a form and all the queries are called from the DAL.
My code is as follows:
private void btnQuery_Click_1(object sender, EventArgs e)
{
PwdSecurity p = new PwdSecurity();
uipc = this.Parent as UIPCMainForm;
const string constrallowedBlockTypes = "allowedBlockTypes";
DAL d = new DAL(uipc.StrUserName, p.base64Decode(uipc.StrPassword));
DataSet ds = new DataSet();
ds = d.AllowedTypes(constrallowedBlockTypes);
BindingSource bs = new BindingSource();
bs.DataSource = ds;
bs.DataMember = ds.Tables[0].TableName;
dgv.DataSource = bs;
}
DAL:
myConnection =
new SqlConnection("server=PTLLBNB0DD1\\SQLSERVER2005;database=IPControl;Trusted_Connection=yes");
public DataSet AllowedTypes(string Type)
{
string SQL = String.Empty;
ds = new DataSet();
try
{
SqlCmd = new SqlCommand("spGET_ALLOWED_TYPE", myConnection);
SqlCmd.CommandType = CommandType.StoredProcedure;
SqlCmd.Parameters.Add("@Type", SqlDbType.VarChar, 50);
SqlCmd.Parameters["@Type"].Value = constrallowedDeviceTypes;
if (myConnection != null) { myConnection.Close(); }
myConnection.Open();
SqlAdapt = new SqlDataAdapter(SqlCmd);
SqlAdapt.Fill(ds);
}
catch (Exception e)
{
MessageBox.Show("DAL Layer / AllowedTypes method error. \n\r \n\r" +
e.Message.ToString() + " \n\r \n\r" + SQL);
}
finally
{
if (con != null) { con.Close(); }
if (aCommand != null) { aCommand.Dispose(); }
if (adapter != null) { adapter.Dispose(); }
}
return ds;
}
If I had access to the SqlAdapt, I could probably use SqlAdapt.Update(ds), but i don't currently.
Any suggestions?

Please clerify. That picture doesn't have any connection to your question and i don't understand the writing

I konw this method,but that ont isn't what I want.and thank you advance.
I will look for a new method to deal with this question.

I want to replace the double backslash with a single backslash. The following code does not work.
pResult.Path = pResult.Path.Replace(@"\\", @"\");
It does not do any replacement at all. How can this be accomplished?
|
|
|
|
|
That should work as is. If you're looking at it in the watch window, be mindful that Visual Studio already escapes special characters with a slash. If you click on the magnifying glass (the visualizer), you should be able to see the 'unescaped' version of the string.

You are right, it did work. Thanks for the clarification.

Hi,
here is some code I've been using for that purpose, it was aiming at JPEG though:
FileStream stream=new FileStream(fileSpec, FileMode.Open, FileAccess.Read);
Image localImage2=Image.FromStream(stream);
#if true
int[] piList=localImage2.PropertyIdList;
Dictionary<int, string> propNames=new Dictionary<int,string>();

Hi,
I'd a DataTable where I'd filled the data using SQL Statement "SELECT CONVERT(VARCHAR,DOB,105) AS DOB FROM TABLENAME".
Here the DataTable is filled with Dates by using the format "dd-MM-yyyy"
My problem is I need to apply the Filter viz., =, >, >=, <, <= on the DataTable based on the input given by the user in the same format "dd-MM-yyyy" irrespective of the datetime setting in the user system.
Can any one suggest on this.
Thanks in Advance

In your select statement include a where clause the would be a built string based on the input the user entered. For example:
"WHERE mydate < CONVERT(DATETIME, '" + "07/01/2009" + "00:00:00', 103)"
Replace 07/01/2009 with logic that would build that part of the string based on the user inputs.

Hi,
Take the input from the user which would be in the form of '=, >, >=, <, <=' and the string with this try to make a filter condition and apply it to the rowFilter of the dataview.You will surely get..

Hi,
I can't see what's wrong with this code. I am getting "1/2/2009 9:00:00 AM" displayed in the textBox when I'm expecting "1/2/2009 9:00:00 PM". Can anyone tell me what I'm doing wrong here, please?
DateTime dateTime;
DateTime.TryParseExact("1/2/2009 9:00 PM", "d/M/yyyy H:m tt", CultureInfo.InvariantCulture, DateTimeStyles.None, out dateTime);
textBox1.Text = dateTime.ToString();
I'm using VS2008 and targeting .NET 3.5 and have "en-AU" as the default Windows culture.
Thanks, Henk.

Thanks stancrm, I was reading up on the "g" you used and that led me to Custom Format Strings at http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx[^] where I realised I should be using h instead of H if I'm wanting to parse the AM/PM part. Thanks for assisting. Regards, Henk.

Hi,
Please let me know how to add a filter for DataGridView so that the user can enter the filter condition in the corresponding column header to filter the rows that match the condition.
I am new to C#. Requirement is simillar to how it is in Mercury Quality center or TestDirector tools.
Hope the question is clear..
Thanks & Regards,
Dhana

Hi,
Since the DataTable source is assigned to DataGridView, you can filter the DataTable by using
DataTable.DefaultView.RowFilter="ColName=" + ColValue
It will automatically apply to the DataGridView

Thanks very much..i am now using the simillar code for implementing the filter.

If this is a bound DataGridView, you are not allowed to add rows. Hence you will need to extend the DataGridView if you need a filter like Quality center.
A quick and dirty (and may be "not recommended") way is:
1. Provide padding the headercell.
2. Add a textbox to the DataGridView at the location right above the first row.(You will need to play with the location of the textbox)
3. Handle its TextChanged event and set the RowFilter property of the datatable you have.
A better solution IMO will be to have a button and display a modal window where in user can apply filter.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD
