View 3 RepliesI have a button on a web page that I just need a little help with some extra code. I think I need a TRY, CATCH statement?, this is what I have so far: I have a simple web page that has a button which at the moment when pressed enables the user to add data to a DB table via a stored procedure.Once this button is pressed a pop up message box is displayed to let the user know the data has been passed. The user then needs to press the 'OK' button within this message box which then directs them to the home page of the site. This works fine.
The code for this is here:
Protected Sub btnAddRawData_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddRawData.Click
'database conn, this is linked to the web config file .AppSettings
Using dbconnection As New SqlConnection(ConfigurationManager.AppSettings("dbconnection"))
[code]....
As I don't want the user to enter duplicate records in the database (This could be done by the user navigating back to the page where the btnAddRawData_Click is located and pressing it again.), I have created a UNIQUE INDEX named 'DupRecords' to stop the user from commiting this data more than once that day.When I run the web page now I get the following message in my browser:
Cannot insert duplicate key row in object 'dbo.GasRawData' with unique index 'DupRecords'.The statement has been terminated.The solution I think, is to add a TRY, CATCH statement into the btnAddRawData_Click code.

I'm adding multiple combobox controls to a form dynamically, but am having a problem with one of the event handlers. The first event handler I've added (for the Leave event) fires, but the second (for the TextChanged event) does not. I've tried reversing the order when adding the handlers and I get the same results (TextChanged does not fire). Here's a code snippet for adding the controls, and the code for the events. I've added a breakpoint while testing to verify - but it never hits the code.
Dim cbo As New ComboBox
cbo.Name = "cbo" & fldName
cbo.Tag = fldName.ToUpper
cbo.Top = rowtop
cbo.TabIndex = tabOrder
cbo.DropDownStyle = ComboBoxStyle.DropDown

I'm having a problem with a Web Control that is dynamically created and inserted in my page. I create a couple of LinkButtons, depending on the data of the search that was made, and I'm trying to add an Event Handler to each of the Buttons, so it would filter the result. The controls are initialized properly, but the event is never fired.
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
Controls.Clear()

I have two usercontrols. One is loaded statically another dynamically.In the aspx page I can write as follows for static user control.
ProgramAddSchedule.onNewProgram += new AddProgram.OnNewProgramClick(onNewProgram_btnHandler);
But dynamically loaded control's event I am not able to get
Control myUserControl = (Control)Page.LoadControl("~/View/EditScheduleProgram.ascx");
How do I get the event of the dynamically loaded control?
Is it possible to dynamically direct a particular control's event to use a predefined method.For example.I have a form which I dynamically add controls to, let's say, TextBox1,TextBox2 and TextBox3 and a module which as 3 routines, Method1, Method2, Method3. When I dynamically add my controls, eg TextBox4, I want to choose which of the 3 methods I want mapped to which event.
.
Dim objTextBox1 as new TextBox
dim NameOfRoutine$="Module.Method2"
Form.Controls.Add(objTextBox1)[code]........
I am passing some values from a Gridview Update Click event to a popup ASP.net page that dynamically builds a series of textboxes in a Placeholder based on the number of sentences that are found in a specific cell of the Grid Row selected.The boxes that are built represent each sentence found in the cell of the selected row. Each sentence is presented for translation, where user enters data into a 2nd dynamically generated textbox.This all works great.Now I have a Listbox beside the 2nd textbox, which sometimes has 1 or more variables that need to placed into the translated sentence. I have set up a Hover menu over the listbox so that I can select the variable and insert it at the end of the sentence in the 2nd textbox. My problem is generating the click event on the dynamically created Listbox. Something like....
Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = TextBox1.Text & ListBox1.SelectedValue

I have a project setup, where depending on a certain variable one of two controls will be used. Either the default webbrowser or the gecko control. Now I can load either one fine dynamically but I can't work out how to use either one depending on a variable result.To load the one I know I want is easy enough..
Code:
Private WithEvents wb As Skybound.Gecko.GeckoWebBrowser
wb = New Skybound.Gecko.GeckoWebBrowser()
Me.Controls.Add(wb)
[code]....
I want my webbrowser to be called wb as I already have all the event handlers written.
I have a linklabel on a form (called LinkLabel1) and I want to remove the underline of the control.I know you can change the font ect and it has a tickbox for underline..However, I want to remove the underline during runtime (using code).how to remove it using code during runtime?

I am building a program with the Webbrowser control that goes onto a website, on the website i have a div with a javascript onclick event that I want to 'activate' or be clicked. The when the div is clicked( the class of the div makes the div seem like a picture) a form above the div is submitted. I want to do this with VB code but the problem is thata) im not very experienced in VBb)the div only contains the following code
<div class="class1" onclick="javascript:document.getElementById(form2).submit();"></div>
I am a little confused to use this script and how it actually works?Here is my script:
<script type="text/javascript">
$(document).ready(function () {
$('#<%=TextBox1.ClientID%>').change(function () {
$('#various3').attr('href', $(this).val());
});

Now if I click the button it should open the iframe and display the message which I am able to do.Now the problem is how do I call the button1_Click event which is in the codebehind at the same time. I have used OnClick and OnClientClick event as shown below but it's not working and I'm not getting any errors.
I have an Application with 2 forms
Form 1 = FrmWindow this is an MdiParent Form
Form 2 = FrmInput this is an MdiChild Form
On Form 1 I have a Menu that's says New Input the onclick event looks as follows.
Code:
Dim ChildForm As Form
ChildForm = My.Forms.FrmInput
ChildForm.MdiParent = Me
ChildForm.Show()
This works and opens the FrmInput as a child of FrmWindow. On the form FrmInput I have two Textbox Controls and 2 Button Controls.
Textbox 1 = TxtName
Textbox 2 = TxtEmail
Button 1 = BtnSave
Button 2 = BtnExit
On the On Click event of BtnSave I have
Code:
SaveInformation()
The Public Sub for SaveInformation Looks like this.
[Code] .....
So when you click the save button it inserts a new record into the table TblInformation on my SQL database, everything works great. Now my problem is I want to be able to open multiple instances of the form FrmInput at the same time. So I changed the New Input button to the following:
Code:
Dim ChildForm As Form
Dim ChildInstance As New FrmInput
ChildForm = ChildInstance
ChildForm.MdiParent = Me
ChildForm.Show()
This works and I can now open up mutiple instances of the form FrmInput, what I cant figure out is how to save the information on a particular instance.
What is the best way to pass a variable from an OnClick event. To elaborate I would like to bind some data to the button and then when that button is pressed I would like to pass that data back to the code behind and do something cool with it.[code]...
View 1 RepliesI am trying to write an onclick event for textbox but VB.net does not seem to support textbox1.click(). I want to open a new form every time someone clicks on the textbox. Opening a new form is no problem, but I cant detect the click. Is there any event for textbox that detects click event? I saw something like TextboxBase that has Click but I am able to use it well.
This is how my class looks :
Partial Public Class TextBoxClick
Inherits System.Web.UI.Page
End Class
It has some basic load and init events. I am trying to write a Sub like this :
Private Sub incident_clicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Incident.OnClick
Incident.Click does not work either.
I am guessing I need to import some class to access the Click event but I am not sure which.
I am working with a .Net 1.1 web application. There is a Save button that, when clicked, will pop up the Javascript confirm box. Once the user clicks OK a long running process is kicked off. We would like to show a busy indicator when the user clicks the OK button of the confirm dialog.
View 3 RepliesI have a bunch of divs on my page that are added at run time dynamically. When any of the dynamically added divs are clicked - All need to call the same function in my code behind. Each of the divs must pass it's own ID to the function. I can't use web methods as the function needs to identify which div was clicked and then show/hide/populate other controls on the page.
