I ran into a situation where FindControl was returning a control that wasn't a complete match of the Id I was searching by. There are two controls in the parentcontrol with similar Ids like: "MyControl" and "MyControlAlternate". When I call FindControl("MyControl") the control returned is "MyControlAlternate". I was wondering if anyone had any explaination why or thoughts as to what might be causing this problem. The way I got around this was implementing my own version of FindControl.
I created a simple page with one button, then on the click event have it use FindControl, to get a reference to itself. But..... FindControl is returning nothing.
code
Protected Sub EntryDoor1_Click(sender As Object, e As System.EventArgs) Handles EntryDoor1.Click Dim control = FindControl("EntryDoor1") control.Visible = False End Sub
but when i run the query in my project the reader in not reading correctly...even if values are present is returns false and if values are not there then it returns true.
I have an application where I read a text file into a richtextbox and I am searching for an especific string then I should get the line number where the string is located, but I am getting a wrong result. Got to be something with my code and I can't findwhat's wrong.
Dim Index, Line, MaxLine As Integer Dim FileText As New RichTextBox '
I have a DataList inside a DataList that causes my page to lose the controls. The page works and there are no errors, but my label is never found! This is odd because the label shows on the aspx page, it just doesn't remove the 2 items that I want it to remove. When debugging, it skips over the If statement altogether:
If lbl IsNot Nothing Then If lbl.Text = "Self Directed" Or lbl.Text = "Systems" Then lbl.Visible = False
[Code]....
This will only hide the text for "Systems", I have gone through each label in that particular question and each has hidden itself. This code does work on another page so I know that Self Directed is exactly how it is capitalized. I even copied and pasted from the database and it still wouldn't hide.
I have a literal8 inside panel1 and panel1 inside datalist1 ..
i wanna insert the value in literal1 on page load event using query string ...
ERROR on Page Load : Object reference is not set to the instance of an object
how to make this code workin ?
Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit Dim lit8 As Literal = DirectCast(DataList1.FindControl("Literal8"), Literal) lit8.Text = Me.Request.QueryString("room") End Sub
Ive tried searching for hours now and cannot find out why my code (aka, me.) is failing
Basically... I have a listview control which I'm passing a datatable of products (ID, Name, Description and Price columns), and im trying to make it so that when the "checkout" button is pressed, it parses through all the controls on the page, finds all the controls with the correct ID's and adds the items values to the cart.
ive checked all my ID's in the source code and they match up to the ones being requested by the FindControl method.[code]...
Dim tabnum As Integer = mycontrol.TabIndex If My.Forms.Sessions.GroupBox1.Controls(tabnum).Enabled = True Then mycontrol.ForeColor = Color.Red[code]....
I have checked and double checked the tab order on the controls and run traces with debug. The control found in my.forms. sessions. groupbox1 seldom returns the proper tab. Using a 'watch' I can see the tab names and the tabname (my.forms.sessions. groupbox1. controls (tabnum).name is often the incorrect one.
I'm trying to include a user control in an aspx page, it works fine, but my control does position itself where I want it and always appears at the very top of the page. Could it have something to do with the masterpage? I've tried registering the user control in the master page, but I don't know how to reference it in the content page.[code]
I've built my first usercontrol for use in a GPS Mapping forms app.
pic1 shows "panel1" containing some picturebox "tools" with a map(another panel containing a picturebox) underneath.
Pic2 shows that I dragged the map and the "tool" have not moved with the drag.
"panel1" also contains my usercontrol( this will show a transparent map scale). My usercontrol and all the "tools" definately have the same parent - ie "panel1".
If I resize the form to cause a re-paint of all the controls I get Pic3 - the red T bar (my usercontrol) will be the map scale.
Everything looks OK until I drag the map - the user control goes with the drag. Pic4 shows that the usercontrol image has been erased as it passed under the "tools".
I don't understand why the "tools" stay put and on top of the map and the usercontrol does not - even though they all have the same parent.
I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.
I have this database and I need to load it with a visual basic form in Visual Studio 2005.The database has 6 tables and they contain wrong data that I must filter when loading the database in the form.
A quick example:First table is Category, which has 3 fields (id, name, description). In one record I have 2a for id (a numeric only field) and in other record I have m1lk for name (a string only field).
When I click a button I load the database into a DataGridView control. How do I stop visual basic from loading into the DataGridView control those records that have invalid data (like in my example).
I have try with SQL queries using WHERE and LIKE, like in
SELECT IdCategoría, NombreCategoría, Descripción FROM Categorías WHERE (NombreCategoría LIKE '[!l]%') AND (IdCategoría LIKE '[!abcdefghijklmnñopqrstuvwxyz]')
but it's really difficult to filter things like Angel* and P3ter and Hood8, all at the same time..
I have a WebBrowser control in a VB.NET WinForms app. I am able to set the default printer from code and print without prompting the user. However, there is also a print button that shows the PrintDialog. If this action is done first the page will print.Then if I try to programmatically print later (again setting the default printer to some other printer) the it will print to the last printer selected in the PrintDialog box even though I am resetting the default and see the default printer being changed in Windows.It works fine unless ShowPrintDialog has a printer chosen first. Once that occurs it seems to always use that printer no matter what I do.
For Each strPrinter In PrinterSettings.InstalledPrinters If strPrinter.Contains("My Printer") Then wScript.SetDefaultPrinter(strPrinter)
This morning I was trying to work out how to update a User Control from a button on a page using jQuery.Refresh User Control with jQuery.From the info gleaned from this article: http [url]...I now have a method of loading a User Control as a page with jQuery using the converted .VB example from the codeproject.com article.However... this won't render into the browser, Firebug is giving the error "element must be contained within a form runat=server tag" So I posted this question:
re: better way to manage a dynamic select list using jQuery and User Control.Since posting that though,I have thought about it further, and believe it is the fact that the jQuery Handler class created by the codeproject code is send the browser a complete page.Given that I sadly don't really understand what that codeproject code actually does I am having trouble working out how to alter it.What I need it to do is not return a Page at all, but I guess, an HTML string, which can then be pasted directly as HTML into the div as required.how to alter that code to return an HTML string?
This isn't really a VB specific question. It's .Net in general... if you have ideas in another .Net language, let me know... I know most of the .Net languages (I don't know that foxtrot or what not weird ones). Furthermore this isn't a 'I don't know the method on some class I should be using' kind of question, it's a design/problem solving kind of question.I'd like to know how you'd approach the problem with in the boundaries set.
I am trying some Uiculture change functionality. In that I need the name and text of controls in a form to change the culture. I got some Demo project and it is in C#. I tried to make the same functionality with the C#.net and Also using VB.net. But the below mentioned code returns control name with an underscore as prefix. But I don't want underscore. Code is actually written in Class library. It works perfectly in C#.
Code is written below Dim fields As FieldInfo() = form.[GetType]().GetFields(BindingFlags.Instance Or BindingFlags.DeclaredOnly Or BindingFlags.NonPublic)
I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?
I have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such: Dim orgNameString As String = getOrganizationName.getOrgName(organizationID).ToString() Dim myOrgName As Literal = FindControl("orgName") myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal) If Not (myOrgName Is Nothing) Then [Code] .....
Is this the right declaration of findcontrol for complete step of createuserwizard1 ?Dim UserName As TextBox=CreateUserWizard1.CreateUserStep.Content TemplateContainer.FindControl("Label11")But when i use it its shows the error object expected !
I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.
Friend WithEvents Panel1 As System.Windows.Forms.Panel Friend WithEvents btnAdd As System.Windows.Forms.Button Dim ButtonCount As Integer
I have an ASP.NET web application (VB.NET) using an Oracle database. On an insert, I need to get the identity of the inserted row back. I am trying to use RETURNING, but I keep getting a value of 1 returned.
Dim strInsert As String = "INSERT INTO L.TRANSACTIONS (LOCATION_KEY, TRANS_CREATOR, TRANS_EMAIL, TRANS_PHONE) VALUES (:location_key, :trans_creator, :trans_email, :trans_phone) RETURNING TRANS_ID INTO :ukey"
i am trying to retain the value of a variable from a previous page. i believe this is the C# way to do this, but i would like the vb.net way can someone please help:
I created a row (header row) in a gridview with a dropdownlist among other input controls. I also put a button on that row (fltbttn-see below).I created an addhandler for the button called fltbttn_Click.I want gain access to my dropdownlist(ddlscantype) using findcontrol but how can I get to the header row where the filter controls exist?[code]......
How do you get a specific nested control of dynamically created controls (i.e. the child of a dynamic control)? The FindControl() method does not work because it only deals with TopLevel dynamic controls I believe.
I have a web page where I want users to enter ratings for a particular software. I have got this working fine. What I am after now, is that users need to be logged in to enter ratings. I have dragged the loginview control onto the page and dragged all the other controls/datasources into this view. However now I am getting alot of squiggly lines regarding my controls not being declared. I have been told that I need to use the FindControl method. However I'm not sure on how to use it in my instance as I have a dropdownlist involved.
The controls are called: LoginView1, DropDownList1, TextBox1 and Button1 for the insert.
Any proper declarations so I can insert data into my database. Here is the code as it stands outside of the loginview: Sub doInsert(ByVal Source As Object, ByVal E As EventArgs) Handles Button1.Click [Code] .....
My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".
Here is my code for all 3 forms.

These are forms to calculate the cost of getting a cell phone package.
