Web Forms :: DynamicPopulateExtender And Function Routine?
May 1, 2010
My webform has 4 fields: Food Rent Utility subTotal
I'm using DynamicPopulateExtender for Food, Rent and Utility to update subTotal whenever there's a value enter.
Question #1: Do I use customScript or ServiceMethod that link to the function below
Protected Function UpdateSubtotal(ByVal nEntry As String) As Integer
Dim oldSubTotal = Eval("Subtotal")
'Bind("Subtotal") = oldSubTotal + Eval(nEntry) <--- I know Bind("Subtotal") don't work because Bind is not declared
End Function
Question #2: How do I update Subtotal value on the webform?
I have a MySql database in which I store user names. Now on the search page of my site I want to populate search results without posting back, I googled it and found that the DynamicPopulateExtender can do it but I have no idea how. What I have done is...there is an asp:textbox named "txtSearch" and an asp:button named "btnSearch" and an asp:panel (extended by the dynamicpopulateextender) and i want do display results on this panel, remember in order to retrieve results i have to connect to the MySql database.
I have a web form with lots of code behind a button. I want to create a class, put all the code form the button into the class. But how do you call routines in the button from the class?
I'm looking at automating some reporting that I'm going to be generating. I want the reports to be generated and emailed at a particular time every day. These times will vary, and so will the types of reports.I was wondering if there were any better solution to creating a routine with a timer that executes at a set time every day? If I include this class and routine in the Application_Start of my Global.asax, will it always be running, or is there some awesome EventListener that I'm not aware of?
I'm using "Ajax:dynamicpopulateextender" control, trying to update multiple textbox whe user introduces a value in ohter textbox.t works fine when I need to update one textbox, but what I need is looking at the DB, retrieving some values and put it into 5 textbox.I have a WebService method, but I'm not be able to find the controls using the id.I've tried this:
[Code]....
[Code]....
I have a textbox with id "CifTB", but I dont' know ho to reference it form the WS method
in .vb file, in a class i have created a button control, assigned its ID, and other properties.
In code behind file of a aspx page i have created object of that class.Run the page and browser Button control is coming. Now i want to do something in its click event.
But i am confused how to define that one, since presently there is no any button control instantiated.It is getting instantiated at the runtime.So, how to define its click event or any other events ?
WebuserControl holds a button that trigger a database operation. As soon as I click on button inside webusercontrol the whole control disappears, leaving behind a blank modalpopupcontrol. Remember there is no postback happening as modalpopup has updatepanel as its first child. Everything is inside this updatepanel.
Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:
I'm trying to do a number of large queries in the same routine, and have a label in an updatepanel update after each one. I must be doing something wrong, however, because whenever I fire up the routine, my label won't update until the last query is done. Isn't it possible to do UpdatePanel.Update multiple times in the same routine/event? This is the code I'm using:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click lblStatus.Text = "Busy with task 1" UpdatePanel1.Update() LongTask() lblStatus.Text = "Busy doing task 2!" UpdatePanel1.Update() LongTask() lblStatus.Text = "Done!" UpdatePanel1.Update() End Sub
Private Sub LongTask() conn = New SqlConnection(connstring) conn.Open() cmd = New SqlCommand("Select * from very_large_table", conn) cmd.CommandType = CommandType.Text reader = cmd.ExecuteReader() End Sub
When the form loads, the lblStatus is emtpy. When I click the button, I see the page loading until it displays 'Done!'. I don't see the other texts. This is the page source:
In my application, there's a module that displays a user's assignments. Sometimes these assignment descriptions are pretty long that's why I display up to 500 characters of the description. However, because I use an HTML editor in the app, if I blindly grab the first 500 characters, there's a good chance the description will look very funky due to missing HTML tags. So, I first need to strip off all the HTML tags, then grab the first 500 characters. Before I re-invent the wheel, I wanted to see if someone else has already tackled this issue and would be kind enough to share his/her code with me.
I have a GridView with Cell 0 containing the ID that I need to pass to a Public Sub.
I cannot figure out how to pick the value from Cell 0 in order to pass it to the Sub. I have tried experimenting (see the Dimmed EventID below) but have failed. Here is my code:
Protected Sub gvAppointmentsCalls_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvAppointmentsCalls.RowCommand Dim EventID As String = gvAppointmentsCalls.Rows(e.RowIndex).Cells(0).Text If e.CommandName = "gvAdd2Outlook" Then Send_iCal_Call(EventID) End If End Sub
If I type the value directly e.g. Send_iCal_Call(123) then it works perfectly.
Public Sub Send_iCal_Call(ByRef Event_ID As Integer) ' My code in here End Sub
I am writing a web application and one of the save routines calls another sub routine as passes two parameters byref. the sub routine gets the data required and assigns it to the passed parameters.
When I look at the results in the main sub the passed parameters are not set, why?
Code: Private Sub GetSiteDefaults(ByRef sCleanerCode As String, ByRef sCheckerCode As String) Dim sqlDASites As SqlDataAdapter Dim sqlDTSites As DataTable Dim sqlDCData As New SqlConnection sqlDCData.ConnectionString = conStringHQ.ConnectionString.ToString sqlDCData.Open()
I am using a adapted version ofhttp://www.mikesdotnetting.com/Article/45/Programmatically-accessing-data-from-DataSource-controlsDon't we need something like a closing-routine / close connection command after getting data from the database?If yes: What is the correct closing command?
That doesn't make any sense at all but what I mean is, if you've got a button for example which takes say 10 seconds to complete whatever is in the button click routine, and somebody else on a different computer clicks the same button just after, is it possible for that second button click routine to wait until the first one is complete? And most importantly is it something fairly simple to do? I'm sure I accidently found some information on this when searching the web for something else but I can't remember what I was searching for before and can't find it now
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.

Take the following scenario. I have multiple ASPX pages. Login, Logout, Main, Messages, etc... They all inherit from System.Web.UI.Page of course. For all the pages, I want to override the Render method from the Page class. I could easily copy and paste the same code into each page like so:
protected override void Render(HtmlTextWriter writer) { //Code Logic Here }
But if I had many pages, lets say 20, maintaining the code in each page could get very time consuming and error prone.That made me think a bit and I thought okay lets try this...override the function in each page but call a static function. That way changing the static function would result in a change for every page.Which works fine... But its not really nice and clean, having to override like that on every single page.
