I have a Database with some tables in an Asp.Net project (C#),I wanna to run a method in C# whenever some data was written in the tables.
I know I have to use triggers, but I don't know how!
P.S:I'm using SQLExpress 2008,
The following stored procedure updates the value in LeaveTransaction table.
[code].,...
My Question here:
I have written the above trigger,which would update the value for the corresponding records in another table ie) LeaveCumulative table. The trigger is not updating the value in the designated rows in the leavecumulative table. Whereas when I excute the same update command separately in the Query Editor window the trigger is working fine.

Now the odd thing at run-time is, whenever a client-side mouseover event is triggered, the app does a full postback. That happens only in firefox.

I am trying to write a quote generator. For each product, there are a set of options. I want to dynamically add a drop down list for each option, and then have their SelectedIndexChanged events all wired up to update the quote cost.
I am not having any trouble adding the DropDownList controls to my UpdatePanel, but I can't seem to wire up the events.
After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this:
Edit: Since programmatically adding AsyncPostBackTrigger controls is not supported, I've change my code to this, but I still don't get the event:
Edit 2: Tried adding a PlaceHolder to add the drop down lists to (instead directly into the ContentTemplateContainer, still no events firing.

I want to dynamically populate a form field from multiple other fields in the form.
If input A or input B is changed, input C should be updated based on the values in input A and input B.
The DynamicPopulateExtender in Ajax control toolkit has almost this. With it I can populate a target based on a trigger.

To provide neat and tidy error urls like "/Error/404/TheNameOfTheRequestedPage". This works fine from VS 2008, but once published to my local machine, I get the default error page:
Error Summary
HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or
is temporarily unavailable
I've chosen not to use system.web/customErrors because I don't have access to Server.GetLastError() from there (or at least it's never worked for me) and I want to get the http code.
I am fairly new to ASP.NET and just started using UpdatePanels.Here's what I'm trying to accomplish. I have a button which is wrapped up in the UpdatePanel like so:
[Code]....
The following is the mark-up for the textbox which is supposed trigger an update when its text changes:
[Code]....
With the current set-up, the button's text doesn't change when the textbox content changes. At first I suspected that the reason it didn't modify button's text was because I didn't set AutoPostBack to true on the textbox (tried enabling and it didn't work though),
but then I why would I want to? I'm not getting any data from the server - I just want to update a button on the client side.
I'd really appreciate if you could point out what I'm doing wrong and maybe also clarify when AutoPostBack is absolutely necessary and what are some of the special cases in which it needs to be used.

THe problem is when i change the Type, i want the other 2 dropdownlists to reset or just the Models dropdownlist.

I'm using Quartz.NET for a system I am creating, where jobs are run via a Windows Service and can be added and editted (inlcuding trigger details) in an ASP.NET page.
I'm having some issues though - I need to be able to modify a triggers details, such as the type of simpletrigger or the cronexpression, and I've been told that I need to unschedule the job then reschedule it. Problem is, unscheduling the job then rescheduling is totally removing the trigger from the job for some reason. Here is my code for when the Submit button is clicked on the edit page:

I am working on an mvc application. Two tables each have their individual submit button. Table1 has default submit on enter key. How do I change the submit button based on textbox focus?
<table>
...<td align="left"><%= Html.TextBox("name")%></td>
...<input id="nameSubmit" name="NameSubmit" type="submit" value="Search"/>
</table>
<table>
...<td align="left"><%= Html.TextBox("idNum")%></td>
...<input id="idSubmit" name="IdSubmit" type="submit" value="Search"/>
</table>
I tried using the panel, but "the DefaultButton of 'Panel1' must be the ID of a control of type IButtonControl".
I have a .js file that works fine locally, but I am somehow having path problems when I commit and add to my server. I have "Home" for the controller name, and "LoadTable" for the JsonResult function.
$(document).ready(function () {
$('#tableClick').click(function () {
$.post("Home/LoadTable", $('#FormTable').serialize(), function (data) {
alert("test");
}, 'json');
});
});
Should I have the path name be something else when published? If so how do I toggle from local to server version in my webconfig, if possible? Is there another option?
I have a web form with an Asp.net PlaceHolder control. By default the control is set to visible false and will be displayed through the code behind based on several criteria. In general this PlaceHolder control wraps several other Asp.net controls. Now a new requirement ask that the controls within the PlaceHolder control be visible at all times an no longer hidden. So in the Aspx code I changed the laceHolder attribute and set it to visible. Now all kinds of Java Script validation errors are occuring and it is a horrible spahgetti code nightmare. Is their a way to set the visible attribute on the control and not have it trigger the validation?

Now here's my problem. When dd1 triggers the postback both dd1 and dd2 get disabled (instead of just dd1) and after the request is complete only dd1 gets enabled back. The behaviour is also true the other way around (if dd2 triggers the postback both dropdowns get disabled but only dd2 gets enabled back). I'm not really sure what to make of this.
I have a problem when viewing my website in Internet Explorer.
When I use any other browser my Gridview works fine but in IE it triggers my VB code twice per click.
So here is the code
[code]....
I am only using the msgbox as a test to see if my issue is resolved. I know not to use this outside of visual studio.
When I use the above in Internet Explorer it fires twice! but in every other browser I have tried it only fires once as expected.
I have created a user control which has a form and 2 buttons; Save and Submit. Both buttons are created at design time. Users can enter details in the form (e.g. title and description of an item) and click Save which does some server-side processing to create an 'Item' then clears the form.
The buttons:
[Code]....
[Code]....
And a placeholder to add dynamically created controls:
[Code]....
I am saving the Items in ViewState and dynamically creating a LinkButton control for each Item which allows the user to edit the item:
[Code]....
[Code]....
Now, when I test this in Visual Studio 2010, it works fine;
1. Enter Item title and description in form
2. Click Save
3. Save button triggers postback and onClick event code is run
4. ViewState list is displayed below the form
When I create a local IIS web site for testing, the postback on the Save button only works the first time I click it. Postback is false on the second click and the page reloads without running the onClick event code.
I have a simple aspx Page, which html contains:
[Code]....
and code behind:
[Code]....
This is quite simple. When I press btn1, it sets correctly the Session Key. And this is then the issue arrives: When I press one of these buttons, this is the sequence of what happens:
Global.asax: Session_Start
MyPage.aspx: Page_Load » btnX_Click
So, everytime there is a PostBack, even before the Page loads, the session starts and generates a new Id. This way, I loose everything during the PostBack. My Session State configuration:
[Code]....
This is running on VS 2010 + V3.5, on IIS5.1. The Page header configuration is default.
SessionStateModule raises a Start event with a new seesion. Is there a pointer to "deep dive" information?
In particular,
(1) I want to preserve Session state information across a postback to external (web-based) services in my VS 2008 development environment, but am finding that my code is triggering the creation of a new session.
(2) I am using IIS to host WCF Service calls, and it appears that many of those calls trigger the creation of a session. I would like to dive deeper into this, and try to manage (reduce) the number of sessions that are created and their behavior.
I am using .net 3.5 framework. I have a Tabcontainer inside that I have place asp.net fileupload control which is inside update panel. It's been known fact that fileupload control does not work under update panel unless we use Postback Triggers.
