I have an application where the user can enter new part numbers. I have a datagrid. They push a button to insert a new line. Since I am adding a new row to the dataset, I have to first initialize the dataset, table, etc.
Where I am running into problems is when the user enters more than one blank line. I can add the first one no problem. But if I want to insert a second blank line, the page always postsback and just resets that first line.
Is there a way to say, "For the first row, initialize everything, but for the second row and beyond, stay on the same page!"

One solution is to disable the insert new button once the new row has been created. How are you binding the data to the grid? Are you doing so at design time, do it from the code behind instead and then you can bind the data whenever you want.

But of course, that's all a "high level" overview of things

what do you mean by read?
To load into a byte array you can do the following.
byte[] newFile = System.IO.File.ReadAllBytes(@"\YourFile.tif");

I want to detect if the client browser is using popupblocker or not.. or is there any solution to popup a window regardless of that popblocker as Hotmail and yahoo shows popupwindow on deleteing of emails

Hi,
What is the method you r using to show popup?
Sushant Duggal.
|
|
|
|

function openMyWindow(){
var PagetoPopup;
PagetoPopup= '<%=Session["app_path"]%>' + "MyWindowName.aspx";
var newWin = null;
newWin = window.open(PagetoPopup,"MyPopupWindow","toolbar=no, location=no, directories=no, status=yes, menubar=no, scrollbars=no, resizable=yes,titlebar=0");
if ( (newWin == null)
|| (typeof(newWin) =="undefined")
|| (typeof(newWin .location.hash) != "string") ) {
alert('Please ensure that pop-ups are enabled!');
} else {
if (self.name != 'MyPopupWindow') {
top.close(); // Use this if you want to close the main/parent window ; otherwise comment out this code
}
}
I hope this is what you wanted.The code notifies the user if the popup blocker is activated, so that the user can de-activate it and try to open the window again.

Hi, I am using C#.NET to create an instance of MS Access 2003. I try to open my Access Report, but the Application just hangs as soon as I get to the part where I open my Database.
Here is part of my code:
oAccess = new Access.ApplicationClass(); //No problem
if(!oAccess.Visible) oAccess.Visible = true; //No problem
sDBPath = "C:\\Reporting.mdb";
oAccess.OpenCurrentDatabase(sDBPath,false, ""); //PROBLEM IT HANGS!!!
// Preview the report:
oAccess.DoCmd.OpenReport(sReport,Access.AcView.acViewPreview, moMissing, moMissing, Access.AcWindowMode.acWindowNormal, moMissing)
My problem is that it stops on the line that attempts to open the DB AND DOES NOT CONTINUE FURTHER.Ohh by the way I wrote the same code in VB6 and it worked just fine.Please help.

The user is not supposed to see anything in the website once he is logged out, that's the very definition of logout. It is very normal that he gets redirected to the login page if you're using Forms authentication in your website.
I'm curious to know how you managed to solve your problem with IE though
