View 3 RepliesI need to add potentially a large number of items to a dataset, this currently works but is quite slow. There are some minor changes I can make to make this fast however the main culprates are the insert statements which are quite complex, With the deletes I changed the structure to be DELETE FROM TABLE WHERE ID IN () Instead of a per ID statement which made quite a difference executing for every 25 rows.The SPROC is linq enabled DbContext.MYSPROC(params) is there a way I could add the Sproc in the context to a batch group that I then execute when the currrent count of insertable items = 25? for each item in insertitems 'Don't want it to execute here
Batch.AddSproc(DbContext.MYSPROC(params))
If Count = 25 THEN Batch.RunSProcs

I am creating entries in a contract table using linq to sql.
One column needs to conditionally be assigned an application number from a range of values.
I'd like to simply increment the max existing value, however it is a multi-user application and I'm concerned about multiple contracts receiving the same app number if they happen too close together.
Is there a way to either force the entire thing to use the same transaction, or to execute both during the same submit?
I'm getting the error "Cannot Find Table 0" when executing an INSERT INTO sql statement. The fishy part is that the code half works -- the new information is submitted to the database. Here the code in question:

I have develop a function in which insert textbox value and grid view value into database.
Problem is that my web method call but it will add some time value into database and give me the following error. Its work once time other can’t work.
An error occurred while executing the command definition. See the inner exception for details.
function addData() {
debugger;
var Customers = new Array();
var desigantion = $("#TextBox4").val();
$('[id*=GridView1]').find('tr:has(td)').each(function () {
var Customer = {};
[Code] ....
My web method
public class Customerdata {
public string code { get; set; }
public string Product { get; set; }
public string Rate { get; set; }
[Code] ....
After once time run then it give me an error.

I just finished building a new version of a web app that imports custom-formatted documents. However, now I just found out that I need this web app to also import custom documents from 3 years ago. I have the code from 3 years ago that imports the older docs...
I was wondering if I could put some type of "if then" statement in my code like " If oldVersionofDoc Then...execute the old code located in this .vb file".
I want to execute a CS Code but before that, i want a confirmation from user, it will be a javascript confirmation box, if the user say yes, then execute the code, or else leave cs code don't execute
below is my button code
<asp:Button runat="server" ID="EmptyButton" OnClick="EmptyButton_Click" OnClientClick="EmptyMyCart()" />
I'm using the following code in an attempt to show a dialog with a list of errors on the client:
if (rollout.ImportErrors.Count > 0)
{
ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true);
}
The error count is non-zero and the following script block is emitted, but the script isn't executing.
<script type="text/javascript">
//<![CDATA[
$("#error-report").dialog("open")//]]>
</script>
If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.
I wrote a code to call some event...
[Code]....
and
[Code]....
js calls this code and I get object reference not set to an instance of an object
[Code]....
I then decided to run the whole thing on the server it uses the same code above but I now have several parameters to pass in and call a slightly different stored procedure
DataSet dsEx = new DataSet();
SqlCommand testcommand = new SqlCommand();
testcommand.CommandText = "spLockUnlock";
testcommand.CommandType = CommandType.StoredProcedure;
testcommand.Connection = sqlLockUnConn;
testcommand.Connection.Open();
testcommand.Parameters.Add("@OffState", SqlDbType.Varchar);
testcommand.Parameters["@OffState"].Value = ViewState["OffState"].ToString();
testcommand.Parameters.Add("User",SqlDbType.Int);
testcommand.Parameters["@User"].Value = lblUserID.Text;
testcommand.ExecuteNonQuery();
testcommand.Connection.Close();
rest of the code follows
The stored procedure uses the parameters to lock certain records, then I use exec spOfflineSystem which executes a series of select statements (as above), then I unlock the records afterwards....no problems however my dialog box on the front now reads
CustomersEC45TG.xml
If you step through the code the filename reads Customers.xml yet on the front end we get the spurious characters....each time this is executed the spurious characters are different. Only every now and then will the correct filename dialog box show.
Here is what I need to do: I need to execute some server side code after a user clicks on a button, THEN I need to execute some client side code. OnClientClick gets invoked BEFORE the onClick; and what I need is the opposite.
Is there a way to do this? It looks like I will have to execute JS code from the server code.
I am calling a simple console application (exe) using process.start. Within this application, I am writing events to the event log.
View 6 RepliesUsing Javascript i am validating a textbox data.when validation fails i need to stop executing code behind file.How to proceed.

View 2 RepliesI have a web project that sends out a customized email after certain user events (like a status change). I also have an SSIS package on the database that pulls in data from one database and updates another database with that data. I want to be able to compare the data and if a particular field's data for that record is different between the two databases is different, I want to be able to use the dll I created for the web app to send the appropriate email.
View 2 RepliesI am beginner to .Net development, so i am looking for a favour.
Question 1 :
protected void Page_Load(object sender, EventArgs e)
{
txtUserName.Text = "Focus";
txtUserName.Focus();
}
I am unable to get focus to my textbox
Question 2 :
I made javascript code for client side validation.
function loginjs()
{
if(document.getElementById('txtUserName').value.length==0)
alert("UserName cannot be blank");
else if(document.getElementById('txtPassword').value.length==0)
alert("Password cannot be blank");
}
this code executes but it is not stopping further code execution. I mean it is only alerts but in addition to that i need to stop further execution.
I have a Global.Asax and Global.Asax.cs file that is specific to my particular Asp.net project. For some unknown reason the code in my Global.asax.cs file is not being executed. I thought that the breakpoints were being ignored, however that is not the case. Because if I try to deliberately force an error to occur, the code is never executed. Below is an example of what I am talking about. The real code in my Application_Start method is not shown below. ANd other methods are not shown as well.
I have tried renaming the Global.asax file and then re-creating it, and that did not work either. Strange because when I try and create a new Global.asax file, the option to create a code behind file is greyed out.
Why isn't my Global.Asax.cs code being executed?
private void Application_Start(object sender, EventArgs e)
{
int x = 1;
int y = 1;
int z=1/(x-y)
}
I can't find the namespace where it's stored - in the view code I can execute Html.TextBox(<name>, <contents>, <html attribs>) and Html.DropDownList(<name>, <select list contents>, <html attribs>) but how do I execute these methods in controller code?
In case you are wondering why on earth I want to do this, rather than using the TextBox object, I execute Html.TextBox(....).ToString() and create html code from these objects.
I hav button on a page. click on it and it works on local system. when i deploy on server. code seems not working. I receive a 'request failed' and truest level error. method even contains 1 simple stmt of 'exit sub'. it's not happening on other pages.

In a button click, I need to be able to hide my ModalPanel and then continue running other code server-side. I currently have it this way:
[Code]....
It hides the panel at the of the event handler because that's when the page posts back. So what can I do to hide the panel and then continue running the rest of the server-side code?
Basically what I'm trying to do is the following:
1. Button_display in my webform simply displays my UpdatePanel via ModalPopupExtender.
2. Button_closePanel_Click will hide my UpdatePanel and then run some server-side code, which would display my UpdateProgress control.
protected void Button_closePanel_Click(object sender, EventArgs e)
Is it possible to check if our code is executing in Integrated Pipeline Mode or not?
There are some ASP.NET class properties that only work in Integrated Pipeline Mode, and I want to avoid raising an exception if there is a way to test if our code is executing in that environment or not.
Here is my code
<div id="AuthenticateUser" runat="server" style="display:block" >
//login control
<asp:button id="ValidateUser" ... />
</div>
<div id="ForceToChangePassword" runat="server" style="display:none" >
//reset password control
</div>
On click of "ValidateUser" button, I do check whether user is valid or not. Based on some condition I do need hide "AuthenticateUser" div tag and show "ForceToChangePassword" div tag. I really like the jQuery fadeIn/fadeOut effect. I can easily do that on client side. But how can I give that effect after executing server side code?
I tried to call javascript method from code behind that method has a fadeIn/fadeOut logic but it seems like that javaScript method is never been called.
