Check it just above your insert statement.
|
|
|
|
|
Check for RegionId.
if (RegionId == "")
// then Insert
else
// Update.
Or if you can't get region Id, check the entry exists in database first. Like
if (RecordExists) // RecordExist is a boolean function which return true or false.
// then Update
else
// Insert
protected bool RecordExists()
{
bool retvalue = false;
// Write the queries which returns the result set
// If ResultantDataSet contains rows
retvalue = true;
else
retvalue = false;
return retvalue;
}

This should really be done in the SQL server using SP's..else you leave your server open to all manner of attacks..
Then you can also do the check in the sp and if exists update rather then insert

Thank you for reading this post. I am new to Javascript and ASP.NET development so please bear with me. I have a page that renders fine in IE but the same functionality gives me error in Firefox. I have a form which has a bunch of check boxes and there is a a particular checkbox lets call it ABC, and clicking on it, it needs to uncheck the other boxes, and if other check box is clicked, it shud uncheck the the ABC checkbox. The checkbox are created dynamically through code in a table cell. My app works fine in IE but not in Firefox. I know there are a few keywords that is Microsoft proprietary, and is not all browser friendly, but i cannot figure out how to change it. Here is my code below. All help is appreciated. the error I get in Firefox and Safari when I click on any checkbox is ctrl.ParentElement has no properties. All help and code sample/corrections are appreciated. Please note: I am a systems support guy who has to maintain pages.
function ValidateCheckedValues( ctrl , isChecked )
{
// Purpose : This function is called when the user clicks on any checkbox in the equipment requirements table on the page
// If the user clicks on the "ABC" checkbox it clears all the check boxes for that meeting,
// but if the user checked any other checkbox, it removes the check from the "ABC" checkbox
try
{
if( ctrl.parentElement.attributes("SubCode").value == "NONE" )
{
if( isChecked )
{
for( counter = 3 ; counter < ctrl.parentElement.parentElement.parentElement.children.length ; counter++ )
{
ctrl.parentElement.parentElement.parentElement.children( counter ).children( 0 ).children( 0 ).checked = false;
}
ctrl.checked = true;
}
}
else
{
if( isChecked )
{
for( counter = 3 ; counter < ctrl.parentElement.parentElement.parentElement.children.length ; counter++ )
{
if( ctrl.parentElement.parentElement.parentElement.children( counter ).children( 0 ).attributes("SubCode").value == "NONE" )
{
ctrl.parentElement.parentElement.parentElement.children( counter ).children( 0 ).children( 0 ).checked = false;
}
}
}
}
}
catch( ex )
{
alert( ex.message );
}
}

|

Let me guess... You are calling the function with the name of the element as first parameter instead of an actual reference to the element?
Internet Explorer adds references to the elements in the page as members of the document object. This makes it easy to access the elements, but it's non-standard so it won't work in any other browser.
Use the document.getElementById method to get a reference to the element.
Despite everything, the person most likely to be fooling you next is yourself.

Stop posting and reposting your problem and do the work yourself, or get a different job because you are not qualified for the one you have. Either way, I don't care, but stop littering the CP forums with your garbage.

Hi,
I have a GridView that fits my page perfectly. It's set to 800px and I have each column's width set to 10% - there are ten columns. Unfortunately, when I click on the Edit button (a command field), the width of the GridView is screwed up - it extends beyond the width of the browser window. I've tried setting the ItemStyle-Width and ControlStyle-Width on each column with no effect and I've also tried setting the EditRowStyle Width to 800px again with no effect.
Can someone tell me what I'm doing wrong and how to control what width the edit row should be?
Thanks

Provide the width measurement only in percent like 50% or 100%. Pixel measurements will always have display issues.

First of all use the CODE tag whenever you are posting code. your current code is unreadable.
ok so You are not closing the existing connection. close the connection as soon as you finished communicating.
i.e. after using the reader/datatable/dataset, insert/delete/update query.
if you are closing the connection and then also you are getting the error, due to very busy website. change the MAX POOL SIZE in the connection string.
connectionString="Server=XXX;Database=XXX;User Id=XXX;password=XXX;connection timeout=0;Max Pool Size = 100;Pooling = True"

Thanks for your reply
I have corrected CODE tag
I know that I am not closing the existing connection, but I do not know which, that's the problem
Thanks Anders

|

In your code
return SqlHelper.ExecuteDataset(ObjDBAbstract.GetConnectionString(), "users_list", Guid.Empty);
in the ExecuteDataset try makng use of the USING statement, this will automaically close and dispose of your connection

Hi,
I have a GridView which is teamed up with a DetailsView and they work fine. I've added New, Delete and Edit buttons to the DetailsView and that all works fine too.
The problem I have is what to do if there are no rows in the GridView. The DetailsView shows nothing, not even the buttons so I can't simply add a new item from there.
I can create a new button which will open a new page to create a new item but this seems very clumsy and inelegant.
Can someone suggest a better way of doing this? Is it possible to force the display of the DetailsView rows including the buttons, even if the GridView is empty?
Thanks

I'm using this code to run process:
"...
_apppath = String.Concat(_apppath, "zvprtcfg_win32");
string _command = " Zan Image Printer(fax) print.html = ";
_command += strHtmlFileName;
try
{
Process _proc = new Process();
_proc.StartInfo.Arguments = _command;
_proc.StartInfo.FileName = _apppath;
if (_proc.Start())
{
int _i = 0;
do
{
_proc.WaitForExit(1000);
if (_proc.HasExited)
{
_bOk = true;
break;
}
} while (_proc.Responding && _i++ < 30);
if (!_bOk)
{
_proc.Kill();
}
}
}
catch (Exception eproc){}
..."
This works fine with my XP machine with IIS V5.1, but I can't make this work with Server 2003 and IIS V6.0.
In Server 2003, the process shows in the task manager, but it doesn't execute as I'm expecting.
ASPNET user run "zvprtcfg_win32" process on my machine and NETWORK SERVICE user run it on Server 2003.
Please give me some advice, solution...
Thanks in advance.

Hi,
I think the problem is the account "Network Service". This one will not have the rights to run your process as you expecting it. Try to figure out what rights for this user are missing (file, printer access etc.).
The network service is the default user for ASP.NET under Win2003 and IIS 6.0. Maybe you can figure out how to change the default use, so that ASP.NET is executed with other permissions.
Hope this helps you a bit.
Regards
Sebastian
P.S. Have a look at the event log of Windows, there you will find some information about critical operations etc, which where denied.

Thank you very much.
Everything you wrote I already know, but I totally forgot "P.S." part  . And there (at the Event log) was solution to my problem.
Thanks once more.
Regards,
Nina
My problem was:
The machine-default permission settings do not grant Local Activation permission for Internet Explorer to the user NT AUTHORITY\NETWORK SERVICE.

I captured the value of Id of the browser using Request.Querystring but the problem is the value caputered had "+" symbol which is not being shown. Its taking as a concatination.
How can i handle.
|
|
|
|
|
The querystring will convert + sign to white space character. You have to write code for track this.
|
|
|
|
|
You need to make sure the querystring is URL Encoded. I use the following function that i find useful
Public Function Encrypt_UrlEncode(ByVal textToEncrypt As String) As String
Try
Return System.Web.HttpUtility.UrlEncode(textToEncrypt, System.Text.Encoding.Default)
Catch ex As Exception
Throw ex
End Try
end function
In your code before you redirect do something like this
Dim queryString as string=Encrypt_UrlEncode(WhatEverStringYouWantToPassAsQueryString)
response.redirect("http://www.abc.com/RedirectPage.aspx?Q=" & queryString)
Good Luck

Hello,
I have a asp:listView control bound to a LinqDatasource, works fine.
In code behind (as a result of a buttonclick somewhere) i would like to get a dataitem from the datasource (or maybe the ListView) based on the Listviews SelectedIndex.
Tried to get it from listview.Items[listview.SelectedIndex], but the DataItem member is always null.
Any ideas?
Thanks in advance,
Antoon
