VS 2008 PropertyGrid.BrowsableAttributes Fails When Adding More Than One Attribute?
Sep 11, 2009
I have a class that inherits from control with some custom properties added, and I am using a propertygrid to change the properties at run time. I don't want any of the inherited properties of the control available in the PG so to each of my class properties I amassigning a CategoryAttribute and I am adding the same categories to the PG.BrowsableAttributes collection. When I add a single category to the BrowsableAttributes collection it works fine, but when I add more than one, none of the categories show up in the PG. I am wonding if there is a simple setting in the PG, or if I have missed something setting it all up.
I got a properties class that I send to a PropertyGrid. I want to change the [readonly] attribute of some properties in realtime. Below is an example of such a property in vb.net...
Does anyone know of a way have the PropertyGrid control display a NumericUpDown instead of a DropDown box or text box? One of the properties that I need to capture is an integer and I'd like the user to be able to spin up or down to choose a value instead of typing it in.
I have a page, divided into 3 section. Left Menu, Middle and Right Menu. Left Menu data comes from control, Middle Menu data is sorted on a page and Right Menu links also depends upon page to page so they are set on a page itself as
I'm adding in asp.net (vb) an attribute to an image-button: imgButton.Attributes.Add("myAttr", "true") This is working fine. Now I want to read the attribute, but it does not work: If imgButton.Attributes("myAttr") = "true" Then ..doSomething.. How do I get this thing working?
I have an asp.net repeater. In this repeater I have in each itemtemplate two image buttons. If I'm clicking on an imagebutton, the other imagebutton in this row changes it's URL. I want that this URL is saved, after clicking on another row's imagebutton. So I'm adding in the repeater event ItemCommand Dim imgButton As ImageButton If e.CommandName = "imgBtn1" Then imgButton = CType(e.Item.FindControl("imgBtn1"), ImageButton) imgButton.ImageUrl = "myURL" [Code] ..... While debugging, it still skips everything, because all Attributes are empty (but actually they are not)!
I'm stuck on a problem that I haven't been able solve. I'm making a visual basic program that communicates with an SQL-database. The problem emerged when I tried to retrieve data from the database with the help of SqlDataReader and save data from every row to a list (Customer) with the help of Add-method. It turned out that eventually the list had correct number of objects, but the information was the very same in each object of the list.
We are using the .NET PropertGrid to edit the Usersettings of our application. If we use Strings or integers than it works perfectly. Now we need a propery, we call them "Vendor", that store a GUID of the Vendor from a database. But the user didn?t see the GUID in the PG. he can choose beetwen the venders Names in a combobox. This combobox must be loaded from the database I have start to try to solve that with following
how can i selectively disable propertygrid items, or even categories based on the value of another property? i read somewhere about a typedescriptor but i couldn't find a good example.
I am using VB.NET 2008. I am using propertygrid and have added a few elements. I have 3-4 categories and wanted to know how can I expand/collapse a particular category thru code. I did find a code on net but it didn't work.
I have a custom control and have created some properties for it.When I click on that control, its properties are then shown in the PropertyGrid.The problem, is that I only want to show some of the predefined properties as well as my custom properties.Does anyone know how I can filter out the properties I want shown?
I'm trying to add a custom DropDown to the PropertyGrid for a control. I am adding the TrackBar control. It works fine, except, I would like to have the values updated in the PropertyGrid as I move the TrackBar. As it is now, it only updates the PropertyGrid when I finish and click off the TrackBar... I know the problem lies in the Type Editor. How can I get it to allow interim values to be processed. Is there some callback function I can use?
Here is the Type Converter code:
Imports System.Windows.Forms.Design Public Class Slider Private editorService As IWindowsFormsEditorService
1 - Need to create a kind of composite property, like the font property, that it's showed with a plus sign to expand. For example i need to define a new pen, i need to define the color and the width... 2 - I need to define the color for one brush, but if i create a property of the type brush in the PropertyGrid it appears like "System.Drawing.SolidBrush"
I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?
I get an error when I try to build my project.'SSLAccessFiltercannot' be used as an attribute because it does not inherit from 'System.Attribute'. [code]
I am totally into structures at this point, mostly because of their simplicity in use. I am now working on a "download structure", which allows you to download and keep track on a file.This is the
Public Structure FileDownload Sub New(ByVal URL As String, ByVal DestFilePath As String) Me.URL = URL
I have an app developed in VB that works fine on Vista machines but fails on Win7. The offending line of code merely references a variable stored in a module. Evidentally, something is quite different on Win7. How to I find and fix this behavior?
The code is very straightforward. The error occurs in the Application Startup event.
Public Sub MyApplication_Startup(ByVal sender As Object, ByVal e As ApplicationServices.StartupEventArgs) _ Handles Me.Startup
I have made a small form where I have bound textbox with records from database.Although my code for inserting and updating the record seems fine and working. But when I view the database, tables i see no inserts/updates made there. But When I run my application again, I see the records in the bound textbox but only for some seconds (for around 1 and half minutes), although they are not shown in the database (tables) actually.
When I close the application and run again it after 1-2 minutes there are no more records bound to the textbox, since no records at all.How can this be possible. I don't have any idea what's going on.
I have been using visual studio 2008 and sql server.Code I have been using for ::
'Update the Records Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
I am trying to read through a bunch of sub directories checking to see if the archive bit is set on any file and if so then I intend to create a zip file of the entire folder as a backup copy and then I need to reset the archive bit.
The problem is that I do not want to change any other attributes that may be set and for some reason I do not see a way to retain these while clearing the archive bit.
I am also not sure if the method I am using for checking the archive bit will work correctly in cases where the file is also read only or hidden or other such attribute.
I use a textfieldparser to read a csv file in my app. I set the delimiter to a, Problem is, if there is a field that contains double quotes, the textfieldparser fails. So if I have Example",test. it fails. If i remove the " it works. That's quite odd. How can I fix this.
For some reason i can't select text with the mouse in my application.Also my clients experience the same behaviour.I know it was possible to select a part of the textbox and it stayd selected. Now the selection dissappears and the cursor moves to the front.Only a doubleclick functions properly but selects a single word only.
I wonder, what is the most elegant way of dealing with the dbnull situation. I have a class, with attribute, let's say: "End_Date", which is being read from database. Type of this variant should be date, but as it's the "End_Date", there might be the situation that something haven't ended yet, and in the database in this field I have a null value.
Right now a deal with the problem this way: Dim mEnd_Date ... Public Property End_Date () Get End_Date = mEnd_Date End Get Set(ByVal value) mEnd_Date = value End Set End Property But I am not sure if that's a good way as I don't declare variants as any datatype?
I have an enum set with custom attributes. need to retrieve the attribute value in single statement ...
Public Enum Messages ''' <summary> ''' <value>(MessageText : Do you want to save ?)</value> ''' </summary> <StringValue("Do you want to save ?")> Save [Code] .....
Now I needed to retrieve the enum value like something below. Messages.Save.GetType().GetCustomAttributes...... something is possible in single statement itself?
I need to create kind of a menu in my application in wich I have to set different parameters before I populate a Datagridview with some values.So, the idea is to use a PropertyGris in which from which I can edit some parameters and after that I run a query (with parameters setted by PropertyGrid) tu populate my DGV.For example I create some properties like NAME OF A PROJECT, ID OF PROJECT, RESPONSABLE, etc and I put this properties in a propertyGrid and than the user can interact with the propertyGrid and set value for each parameter, bfore running the query for populating
