How To Textbox Control's Onblur / LostFocus Event Trigger A Server - Side Event

VS 2008 Clicking Grid Row Event?
Mar 9, 2010I am using a grid control from ComponentOne and I had asked their support how I can call a VB code routine when a row is clicked on. They said no such event is available but gave the following code below. In the code below it looks like they are calling the "alert('click')" code when a row is clicked for client side. Is this right? If so, how can I call a routine in the vb code with this? I know this example is C which I can change over. I need to get data from a couple cells on the row that they click and run some vb code.
Code:
> What event is fired when i click a row so I can run code on the .vb code page? Such an event does not exist. You can handle a click on client side using RowCreated event handler:
void C1GridView1_RowCreated(object sender, C1GridViewRowEventArgs e)
{
if (e.Row.RowType == C1GridViewRowType.DataRow)
{
e.Row.Attributes.Add("onclick", "alert('click')");
}
}

Application Accessing Event Log On Windows Server 2008 R2?
Feb 21, 2011Can anyone explain why the following happens:My ASP.NET application requires access to Application event log.When I access web application initially, it returns "Security" exception (which is expected, as I haven't granted permissions to write to Application event log yet). Then I give read/write permissions to IIS_IUSRS group on the following registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetserviceseventlog. As a result of this action my web application starts working.Now I remove those permissions I've granted to IIS_IUSRS group. But my web application keeps working (although I'd expect "Security" exception raised again)So, why web application keeps working, although permissions to write to Application loghave been removed?
View 2 RepliesVS 2008 - How To Suppress Server Control Event (onclick)
Feb 18, 2012I have a simple form with a button. The button is server control.
in the OnClientclick event of the button control, I am actually doing some validations. If the validation fails, the onclick event should not be executed. How can I control this?
In the code below, PerformChecks() function gets fired first and alert message pops up fine. But immediately onclick event (which is handled on the server) gets triggered. if the check in PerformChecks fail, how can I suppress onclick event?
Code:
<asp:Button ID="ButtonRun" runat="server" Text="Go"
onclick="ButtonRun_Click" OnClientClick="PerformChecks();" Width="57px" />

VS 2008 - Event Handler For Dynamically Created Button
Jul 31, 2013I'm dynamically creating a table on my page with rows and controls. It looks like a gridview but it's not (it should've been, but too late now, seriously). I have a first name, last name, date of birth, etc. I want each row to have a button to add rows underneath it. So I create an event handler each time I create a new row and assign it to the click event of a button contained in the row. But it's not getting called.
Is it correct that the event handler doesn't stay established because the buttons are dynically created and are lost when the page posts back?
Code:
ImageButton addDependentButton = new ImageButton();
addDependentButton.ID = ADD_DEPENDENT_BUTTON_ID_BASE + currentSubscriberIDAsString;
addDependentButton.ImageUrl = "/Images/btnAdd.gif";
addDependentButton.Click += new System.Web.UI.ImageClickEventHandler(this.AddDependentButtonByRow_Click);
Control[] addDependentArray = { addDependentButton, addDependentDropDown };
WebControlUtilities.AddMultipleControlCellToRow(currentRow, addDependentArray, Constants.CSS_CLASS_TABLE_TEXT_NORMAL);
Forms Data Controls :: Error - Gridview Fired Event "Sorting" Which Wasn't Handled Using Visual Studio 2008
Feb 21, 2010I have a gridview in an update panel which is declared in an ASPX page, and bound to a SQLDataSource in code. The gridview's 'allowsorting' attribute is set to true, and because it is bound to a SQLDataSource, I expect the sorting to be automatically handled.
Yet I am getting the "Message: Sys.WebForms.PageRequestManagerServerErrorException: The GridView 'grdStatusItems' fired event Sorting which wasn't handled" error. I am using Visual Studio 2008, IE8, IIS7. What am I doing wrong? I have done anextensive search for this error, but it seems in most cases where this error occurs, the people are not using a SQLDatasource, so have to handle the sorting event themselves. Is this the case here? Here is the updatepanel and gridview declaration in the aspx file:

VS 2008 Singleton Method - In The Button Click Event, Create A New Reference,?
Jun 11, 2010I just had a few questions about a basic version of the Singleton Method that is posted below. I've just created a very basic class that implements the Singleton Method. Afterwards, I create the first instance in the Page_Load and then when I push a button on the Web Page, I create a reference to the Singleton Class and then print out the "SingletonName" property to ensure that it has a value.
Code:
public sealed class Singleton
{
private static readonly Singleton instance = new Singleton();
[code]....
1) If 2 or more users are concurrently running this application, will the users have a new Singleton Object, or will the user be given the Objects that the first user created? In other words, is this Global to the application or just the session? I believe it is global for each session and not to the application but I wanted to make sure.
2) In the button click event, should you create a new reference, like I am doing, or should I do something like "Response.Write(Singleton.Instance.SingletonName)"?

VS 2008 - No Error Is Generated And No Entry Is Logged In Windows Event Viewer On Server
Sep 9, 2011i made an upgrade to an existing application (still developed by me), while testing on my development machine, everything worked fine. After migrating to a Test Server(windows 2003 server), users can not test the application, it periodically crashes their session and redirected them to the login page (Forms Authentication). No error is generated and no entry is logged in the windows event veiwer on the server. I also noticed this also happens when they try to access a particular page in the application.
The page contains 50 instance of a user-control. Each of the user-control contains 8 textboxes, 2 labels,1 hidden field and 12 asp.net validation controls. I tried saving a copy of this page from Internet explorer (IE8) on my development machine,its about 2.2MB in size.What may be wrong and what tracing tools can i use on my development machine (since it generates no errors). How can i also reduce the size of the page (noting that the asp.net validation controls generated alot of HTML codes)

Apr 24, 2010Using vb.net/asp.net 2005.
I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:

Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
