Re: Datagridview moves to first column when selecting row(s)

It is default behavior of datagridview control.
You cannot change it.

There are two tricks to avoid it.

1. You need to minimize the number of columns to display by hiding some of the columns.

DataGridView1.Columns[2].Visible=False;

2. You can change the order of columns so that the columns that require to be visible
for selecting rows comes first so no need to scroll to right side of the grid.

Use the mousedown event and check the eventarguments to see if it's the right button that is clicked.

Good Luck

Both left and right click can be trapped by using the MouseDown event.
Various mouse down events are trapped in the code below.

       private void form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) <br />
        {<br />
            // Update the mouse path with the mouse information<br />
            Point mouseDownLocation = new Point(e.X, e.Y);<br />
<br />
            string eventString = null;<br />
            switch (e.Button) {<br />
                case MouseButtons.Left:<br />
                    eventString = "L";<br />
                    break;<br />
                case MouseButtons.Right:<br />
                    eventString = "R";<br />
                    break;<br />
                case MouseButtons.Middle:<br />
                    eventString = "M";<br />
                    break;<br />
                case MouseButtons.XButton1:<br />
                    eventString = "X1";<br />
                    break;<br />
                case MouseButtons.XButton2:<br />
                    eventString = "X2";<br />
                    break;<br />
                case MouseButtons.None:<br />
                default:<br />

strBuilder.Append("</table>".ToString());
// string strPath = Request.PhysicalApplicationPath + "\\document\\Test.doc";
string strPath = filename;
//string strTextToWrite = TextBox1.Text;
FileStream fStream = newFileStream (strPath,FileMode.Append);
fStream.Close();
StreamWriter sWriter = newStreamWriter(strPath);
sWriter.Write(strBuilder);
sWriter.Close();

Best way to read a file??

Hi everyone,
Suppose that you have some partly damaged file that you want to copy to somewhere else reading only the good bytes and ignoring the ones that can't be read "getting over them".

I'm using a simple StreamReader in a loop and ignore IOExceptions as they occur but it doesn't work and go very wrong once a cyclic redundancy is encountered..

What would you use?

Richard MacCutchan25-May-10 22:55

You should probably use a FileStream[^] as it allows you to read the file at the pure byte level. in this way you are free to interpret the data without any assumptions made by the framework. You can also position your file pointer randomly hence avoiding portions of data that you know are corrupt.

It's time for a new signature.

Hi Code Gurus

I need to load the PDF document inside the c#.net Application. I tried with PDF Viewer. If i did any changes in PDF form Field i need to track that also. This is not possible in PDF Viewer. So i need any other Control or Way to load PDF inside the Application.

Please send me the Code snap or project link to resolve this problem.

Thanks in advance..

Well Fakeer that is not going to endear you to the forum, asking for the code is frowned upon.

So if you need to edit the PDF you need a PDF EDITOR not a viewer. There are plenty of them around. try doing some research[^]

IQueryable to DataTable [modified]

25-May-10 20:01

Is there option to convert from System.Linq.IQueryable to DataTable with some sort of ToDataTable() function, and avoid looping? Both approaches on
http://www.c-sharpcorner.com/UploadFile/VIMAL.LAKHERA/LINQResultsetToDatatable06242008042629AM/LINQResultsetToDatatable.aspx gives me similar speed efect, but I need speeder. Actually I am wondering if there is something like http://msdn.microsoft.com/en-us/library/bb386921.aspx but with using System.Linq.IQueryable instead IEnumerable? I have few functions that sends System.Linq.IQueryable parameter to this function expecting DataTable[] in return.

Best Regards,

Thank you all, I have similar approach like one in http://peteohanlon.wordpress.com/2008/01/04/extending-linq/, and it is works. But I wonder (because of speed performance) about something like http://msdn.microsoft.com/en-us/library/bb386921.aspx (Creating a Custom CopyToDataTable<T> Method). They said "The existing CopyToDataTable methods only operate on an IEnumerable<T> source where the generic parameter T is of type DataRow. " but wondering is there something equivalent to CopyToDataTable method for IQueryable<T>? Probably not, but maybe somewhere someone offers equivalent method...

I have working function now, but looking for speeding it.
