I have a dropdownlist on a web form that isn't calling a routine when I click on a new item in the dropdown.Here's my code from the .aspx file
[Code]....
[Code]....
My list is populated with a blank item as the 1st entry and then all the alerts that I have in my database. I originally had OnSelectedIndexChanged but that didn't work either.
The dropdownlist selectIndexChanged event never gets called. Why is this?

i have gridview with linkbutton.when i click linkbutton it should call javascript function which returns value would be input for database functions. how do i capture javascript function retun value(i am using Registerclientscriptblock)? and that should be input for database function. Inshort i need to call two function from link button click - one javascript function,one ado.net function which will update value in database. output of javascript function will be input for database function.
function Getlogitudelantitude(address)
{
return "35.3434343,-74.334343"
}
Linkbutton_click(object sender,Eventargs e)
{
register javascript function .. which should return value
string s = "35.34343,-74.334343"
then call database function(s) - does database operation
}
}
I want postback on click of treeview node .So i called a javascript function to do the same. I wrote the following ..On page load:
[Code]....
This is working fine in IE. But it is not working in mozilla and google chrome.
[Code]....
This is the setup in short. I have a big table. Everytime a cell get focus an asyncron call to the server is done (with PageMethods) and some data is returned and updates a infobox in the page.I have written code that makes it possible to navigate between cells with the arrow keyes.
The problem occurs when I shift focus fast through several cells in order to get to the cell I want. Every get-focus is executed and since the communication with the server takes about half a second it get quite irritating and not very user friendly.Ideally I would like to execute only the last focus event. But how? I cant know which event is the last one, can I?
I want to call an action method when an textbox gets focus to get a description of the model object that field is associated with from a database.
I have this jQuery function:
[code]...
It works fine as far as getting the test text, but the problem is if I set a breakpoint in the action method, I see that it gets called over and over, not just when i change focus in the text boxes...
I'm having some trouble getting this to work. basically I got the modalpopup to show, and when it's shown i have 2 buttons (Yes and Cancel). When yes is clicked i want a function to be called. Here is my asp.net code:
----------------------------------------------------------------------------------------------------------------------
<asp:Button ID="btnMpeDummy" runat="server" Text="Test" style="display:none" />
<ajaxtk:ConfirmButtonExtender ID="cbeDelScn" runat="server" TargetControlID="btnMpeDummy" DisplayModalPopupID="mpeDelScn" />
<ajaxtk:ModalPopupExtender ID="mpeDelScn" runat="server" TargetControlID="btnMpeDummy" PopupControlID="pnlDelScn" OkControlID="btnDelScnYes" CancelControlID="btnDelScnCancel" BackgroundCssClass="modalBackground" />
<asp:Panel ID="pnlDelScn" runat="server" CssClass="modalDialog" style="display:none; width:300px;">
<asp:UpdatePanel ID="upnl3" runat="server" ><ContentTemplate >
<asp:Label ID="lblDelScn" runat="server" Text="Delete Iteration" />
</ContentTemplate></asp:UpdatePanel><br /><br />
<asp:Button ID="btnDelScnYes" runat="server"
Text="Yes"
ToolTip="Yes"/>
<asp:Button ID="btnDelScnCancel" runat="server"
Text="No"
ToolTip="No" />
</asp:Panel>
----------------------------------------------------------------------------------------------------------------------
And here is my VB code:
Protected Sub btnDelScnYes_Click(ByVal sender As Object, ByVal e As UI.UIIterationList.IterationListEventArgs) Handles btnDelScnYes.Click
Dim scn As dat.Iteration = New dat.Iteration(e.iterationID, SessUserID)
scn.DeleteIteration()
Response.Redirect("Calibration.aspx")
End Sub
Not sure if this is useful, but just some info: My page have a list of iterations. there are several columns to this table. when the last column is clicked, the modal popup shows and asks the user if to confirm if he/she wants to delete this iteration which is this code:
Dim scn As dat.Iteration = New dat.Iteration(e.iterationID, SessUserID)
scn.DeleteIteration()
so i'm trying to get the funtion to be called, but it's not working. when you click "OK" nothing happens. when i debug it and trace the logic it doesn't even go into the above VB subroutine.

I have a problem with the onclick button requests in ASP, my button is:
<asp:Button ID="btnLogin" runat="server" onclick="btnLogin_Click" onclick="clicked()" Text="Login" />
I need the onclick to be called twice, once for JS client side validation and once for C# serverside validation, when I try this function I got the error saying that only one onclick function maybe called. Does anyone know how I would go around checking both client and server side validation with one click? I've got no idea where to start and the search engines are only returning one of each (either server or client).
I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I have a dropdownlisbox , i am changing the selectedIndex by PageMethod(i.e it will change its value and text on checkbox status). At that time it don't fire the selectedIndexchange method but when i click the button it fires(i.e on postback).

I have a table called "publication" which contains records about Sharkspeare's plays, there are columns called "type", "nortonoxfordnumber", "nortonoxfordtext" and "character". What I like to achieve is to allow users to search the data using both dropdownlist and the textbox. i.e., the listitems of the dropdownlist are Othello, Tempest and twelfth night. Users should be able to type a keyword such as "music" to search within the particular play say "Othello" from the dropdownlist.
I would like to add button click function, and I know that I need to use the query with "and" and LIKE, but I am not sure how to do it as I keep getting the syntext error.
I managed to get some code done, however, I only managed to be able to search one column at the time, here is my code:

I want to execute code written in a dropdown selectedindexchanged event from some another user defined function.
For this i m writing:
ddlMyDropDown1_SelectedIndexChanged(sender, e);
It works when use it in page_load (means the code in ddlMyDropDown1_SelectedIndexChanged is executed) but when i write the same line in another function it gives error "The name sender doesnot exists in current context".
i can populate cascading dropdownlist by using webservice now. but may i know how do i trigger function while selectedindex changed? (without using auto postback...)

I have this import function which can be changed by the client in his desired way.Now I want to code such that if the client tries to import his own data on the page and doesnot give the tags in the order mentioned below his import function should be stopped.
It shouldn't make any changes unless the tags are in the right format because the problem now is if the tags are not in the right format when client changes then its importing over the existing files and directing to an error page which I dont want it should simply stop the import function if they are nt in the order.the code for this function is below

I need to create something which is like an Add friend function in my website which works like this:
1) User types in name of the person he wants to search in the search field and clicks enter
2) on the same page, the search result will come out with an "add friend" button beside every name
3) when the user clicks the "add friend" button, he will be brought to another page (or pop up with a message box?) with a text message field to send to the friend, and a submit button to submit the friend request.
4) over at the Friend's page, he will be able to view the add friend request and decide whether to accept or deny the friend request.
I have two versions of a website. One runs on IIS server on a local PC, the other runs on the ASP.NET development environment included on Visual Studio (localhost). Apart from that, the file stucture of both is the same, although only the one running on IIS works properly, and this seems to be related to the fact that the IIS version calls Application_BeginRequest() where the other doesn't.
I've looked at the differences between IIS server and the ASP development environment in: [URL], and it says that IIS and the ASP development server deal with static content in that for IIS in that on IIS static content does not go through the ASP.NET runtime like it does on the dev environment (but I'm not sure exactly what this means).
I've done a number of tests involving images, etc, and have noticed that when the image is of the form:
<img src="Image/MyImage.jpg...>
the IIS server version calls Application_BeginRequest(), but the visual studio development environment version doesn't.
However, if I change the above code to use:
<img src="<%=ResolveUrl("~/Image/MyImage.jpg")%>" ...>
it will call Application_BeginRequest().
In my case, it is necessary to call Application_BeginRequest because this creates a new path and calls
RewritePath().
The problem occurs when using links such as <a href="..." ...>, because if I use static content it won't call Application_BeginRequest() and the path won't be re-written. But If I change it to href=" %=ResolveUrl("~/...")%>" (for some reason, it will only call BeginRequest() if the path begins with a tilde ~), the path is re-written incorrectly.
I'm not really sure how to find out why the IIS version is calling Application_BeginRequest() from all the time (the callstack just says "external code"), or why it is calling it whereas the local dev server version isn't.
If anybody can explain this, or knows of any sites that go into this so I can master the basics, I'd be very grateful.
Please have a look at my VB/ASP code and tell me if you can see what's wrong (I have bolded the important segments):
[code]...
Basically, I'm trying to get the Page_Load subroutine to execute on the page load, but it doesn't seem to be called. I'm assuming that because I set my feedback label to "feedback" in the Page_Load subroutine, I should see it displayed on the page saying"feedback" on first loading the page and every time I refresh. But this doesn't happen. I'm lead to conclude that the Page_Load subroutine is not being called on the page load.
how come a Null session value that is called, doesn't get directed to the Custom Error Page?
