ASP.NET Usercontrol Property Value Does Not Run Markup
Apr 27, 2011
Well i have a usercontrol with a property "ClientScript" and in the aspx file where i use the usercontrol i set the value to [code]the problem here is that the is litterly passed to the property and not parsed first and replaced by the ClientID..I had the same clientscript applied to a buttons OnClientClick and there it worked...Must i apply some sort of attribute to the property to get this working? [code] i know that im saving to a local variable and that it will be cleared on reload and so on but thats not the problem here.
I have made a usercontrol, it has a property that has a PictureBox datatype. When the usercontrol is dropped on a Form from the toolbox, I want the picturebox property (in the property window) to be showing all the picture boxes (names) that are on the form as a dropdown so I cant select them. How do I do that?
I have a control with a inner TextBox. I want to make a direct relationship between the Text property of the UserControl and the Text property of the TextBox. The first thing I realized is that Text was not being displayed in the Properties of the UserControl. Then I added the Browsable(true) attribute.
I have created a usercontrol in VB2008 that draws a rectangle and has the ability to apply Border3DStyles to the control.The problem I have is being able to select which sides to apply the border on during design time.If you look at the BorderSides property of the ToolStripStatusLabel you will see how it lets you select the sides to apply the border to.
I am making an UserControl which has several properties. One of them should have a specific range of the value - it should only be possible to set the value of the property with a number from 1 to 255. 0 should not be possible, because some calculations are done in which is divided by this property's value. I thought I could use a Byte as type, but a Byte can contain 0 as well. I would like to be able to set a limit for the value of this property, and that an error is shown in the Designer when, in this case, 0 is entered. I mean an error window like you get when filling in 0 for the interval of a Timer. Is this possible with an UserControl as well?
I/we (my class) created a usercontrol that included a picturebox and a timer. We declared the public variable to access the timer enabled property. Placing the user control onto a Form we are able to enable the timer. However, when we went to declare an array for the control we could not access the properties... We successfully declared control arrays using base class control...
In the book I am reading the writer shows code for adding the WordWrap property to a class which inherits System.Windows.Forms.UserControl. But what is the point? There is nowhere to insert strings! Also he shows how to add an event by embedding a Combo in an instance of the class and using its SelectedIndexChanged event to raise the event for the UserControl; again what is the point?
I have an imagelist control in a usercontrol I made. I would like to create a property for this usercontrol, to select multiple images (in an 'openfiledialog'), and adding them to the imagelist inside the usercontrol. So, what's the type of this property? Public Property thelistofimages as [?] It should be an array of images I guess. And then in the 'set' of the property it would add all the images to the imagelist.
defauld the usercontrol create(when is used) the backgroundimage property, but these property can be blocked? i'm asking these, because i need the entire control in that property
I am programatically creating instance of usercontrol as shown below
[code]...
I have two public properties in my usercontorl like clerkName and RespName. How can I set those values in the above code. Intellisense is not showing ClerkName and respName Properties.
I have been making a control and have added a property for a list(of CustomClass). The custom class contains a string, an image and a list of another custom class which contains a string and an image. I have added this property to the designer by adding the browsable attributes and all appears to work correctly with this.
My problem comes when running the program. I can set all of the values within the property and I can go back to them and they are saved, however, as soon as I run the program, the values are wiped out as the property is set to Nothing.In order to allow my property to be edited and saved, I realize that I must initialize the list and have done so in the accessor method of the property (if the property's value is nothing).
I have modified the values in the designer and placed a breakpoint on all of the items which use the property and it's underlying field, as well as on the property's methods itself. The first breakpoint hit is of it being accessed and the value is always nothing.
I'm not sure where the values are supposed to be stored as I have checked the designer code where it would normally store types such as strings and I have checked the resources to see if they have been saved there (like an image would be). After running the code, the values in the designer are wiped out also.
I have MainLayout.master that has UC_Menu.ascx on it. I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I have an enum and a usercontrol, both in the same assembly (a plain .NET 4 web site). In the Constants class:public Enum CrudOperations Add Edit Delete. This controls the columns in a GridView on a UserControl via a property on the UserControl
[Code]...
In C#, I've specified the columns to show with markup as Mode="Edit,Delete", but in VB.NET, this does nothing. The only way I can get anything to show is with the codebehind, but if on the containing page I use userGrid.Mode = CrudOperations.Edit And CrudOperations.Delete, I get all the columns (there's also a delete column), but userGrid.Mode = CrudOperations.Edit Or CrudOperations.Delete shows nothing.
I am writing an application that has to read and interpret data stored in some PDF files. The reading part is done but I am only able to get a dump of all the words on a page and not the format of the words. What I mean is that if I have to extract a table, I am getting the numbers in the table but not the markup which defines the table.Further, there is some formatting used which displays a few of these numbers within parentheses (meaning that those numbers are negative) but the parentheses themselves are not part of the text. Hence, I am not able to distinguish between positive and negative numbers present in the PDF table!
How do you get the PDF markup along with the text? Is a PDF similar in structure to an XML with tags used to markup tables etc.? If not, then, is there a resource which describes the salient features of the PDF DOM?I am using VBA and the Acrobat library (AcroExch etc.)
I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked") IsLockedID (if IsLocked=True then IsLockedID is an integer) IsLockedName (if IsLocked=True then IsLockedName is a string)
I want to show a MessageBox in a VB.NET application that has special markup for its text. More specifically, I want to display an unordered list. I tried doing it by wrapping the text in HTML tags (which Java Swing supports for example, if I'm not mistaken) and working with <ul> and <li>. This did how to do it without creating a completely custom messagebox class?
In my classic asp app, I have a markup page with a bunch of checkboxes. The checkbox control ID is bscv.Once a user checks a box and clicks submit, the value is processed on the next page called next.asp.Based on the value of the checked box, I display the correct dropdown.I use the following code on next.asp to display the correct dropdown.
If bsvc = "master" Then ' only master was checked ' "If the user checks only master checkbox, ...txtmaster with 2 options... is displayed." %> <select id="txtmaster" name="txtmaster"> <option value="">-Select a service-</option> <option value="1">1</option>
I am trying to bind a RichTextBox to data from an XML file where text within a paragraph may be tagged with formatting tags. As an example the text may look like this:"The size of the area is 5000 m<superscript>2</superscript>".Text may also contain other formatting tags such as <bold> or <italic>:"The quick brown fox <bold>jumps</bold> over the <italic>lazy</italic> dog".
The way markup works for those that are unfamiliar is similar to html. For example, in HTML, <strong> is bold and </strong> closes the tag. In Markup, [b] is bold and [/b] closes the tag. Similar yet different.My form consists of 1 Richtextbox named RichTextBox1 and WebBrowser named WebBrowser1.In order to use HTML I use the following code:
Private Sub RichTextBox1_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles RichTextBox1.TextChanged WebBrowser1.DocumentText = RichTextBox1.Text End Sub
When I make an HTML form for MVC 3/VB with the Razor engine, I would expect to be able to do it like this:
@Using Html.BeginForm("Action", "Controller") <fieldset> @* Other form code and values *@ </fieldset> End Using
But if I do that I get "BC32035: Attribute specifier is not a complete statement. Use a line continuation to apply the attribute to the following statement." I need to add an @ character before the opening tag to avoid this error.
With my recent new project with HTML/Markup generator/editor, I have run into a roadblock. Basically here is my code for replacing markup with HTML. The way this works is that the webbrowser has the same text as RTB1. Since the Webbrowser supports HTML, it automatically converts to the style that is specified in RTB1. [Code]
I would like to create a HtmlHelper function for a specific kind of dropdown that appears on many pages in my app. I'm basically just trying to add some decoration around the existing DropDownList function, but it's being encoded.[code]....
but I'd rather make use of VB's inline XML. How do I get the results of DropDownList to not be encoded?
I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName" Dim MyControlType = "TextBox" Dim MyStringValue as String
