From what I can tell, the main purpose of a PagedDataSource is to allow paging of a datasource before being bound to a server control.
If this is the main purpose of this control, why is the AllowPaging attribute's default value False?
I'm only asking as often I will forget to set this as True causing confusion when it doesn't work.
When I drag a label control from toolbox to form, default autosize is true. I need to change to false every time. (I do not like true). How to make default value as false as default value?
View 1 RepliesIn VB6, you can set the Default property of a command button to True / False, and when you push the enter key, it will click the button for you.
What property is this in VBNet / C#?
I'm populating a Repeater with a PagedDataSource and after I populate that Repeater, I want to perform some other operations on the subset of data that makes up the page I'm sending to the Repeater (my CurrentPage Index, PageSize=10). So my question is how to get at those 10 records?
From reviewing MSDN, it looks like I should be able to use PagedDataSource.CopyTo to copy that to a System.Array, but I seem to be getting "Index was outside the bounds of the array." (I'm not sure how I need to be setting the bounds of the array from the PagedDataSource.)
Alternatively, I'd be happy if I could get those records into a SqlDataReader or any other way to read them and do more with them other than just displaying in my Repeater (again, looking for the records from that page that I set as the DataSource on my Repeater) Or, am I going about this the wrong way and is there a way to pull these back out of the Repeater?
Is there anyway to set Specific version to false so that references are not tied to old version numbers, we have a rolling release and trying to remember to set these every time you add a library is a real pain in the.

I was trying the documentprint1 component as i thought it would be easy but cant figure out how to tell it what to print the second part is to print a variable (string) to the printer as well.no need for user to select just straight to default printer with its default settings
View 1 RepliesI have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default.

View 5 RepliesIs it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).

so i have to use an integer when i dim it like:dim b as MyBool = 1 then when you look at it in the watch window b = {Yes} so i could settle for that, but with a boolean you can do this:dim b as Boolean without setting it to anything it defaults to False mine however, is Nothing. 2 things: 1. How can i get mine to default to No 2. How can i make it work like this: dim b as MyBool = Yes instead of having to use the integer this is not a requirement for anything I just wanted to know how to do it

I am converting an application I created using webforms to the asp.net mvc framework using vb.net. I have a problem with one of my views. I get the yellow screen of death saying "A potentially dangerous Request.Form value was detected from the client" when I submit my form. I am using tinymce as my RTE. I have set on the view itself ValidateRequest="false"I know that in MVC it doesn't respect it on the view from what I've read so far. So I put it on the controller action as well. I have tried different setups:

I am not sure why I can't use pictureboxes when its visibility is set to false?? While the picturebox is not hidden, as part of my game I want the user to be able to guess where the picturebox is which means by clicking on it, it should trigger an event but even when I set this event, nothing happens. When visibility is set to true then the event triggers.
I want to be able to trigger events even if visibility is set to false,

A CType(obj, Boolean) would evaluate to False(just as CBool(obj)), i think because the compiler uses a helper function, but that is not my theme. Why does casting Nothing to Boolean evaluates to False, whereas casting an object that is Nothing to Boolean throws an Nullreference-Exception? Does that make sense?
Its my understanding that by adding the ScaffoldColumn(false) annotation to an property in a class, that property will not added to the view when doing Add View. However even though i have added scaffoldcolumn false to properties i dont want added to a Create form, they are still rendered inthe create view. Is ScaffoldColumn broken? On page 552 in Pro ASP.NET MVC 3 Framework by Freeman and Sanderson, it states "If we want to exclude a property from the generated HTML, we can use ScaffoldColumn attribute. When the scaffolding helpers see the ScaffoldColumn attribute, they skip over the property entirely; no hidden input elements will be generated and no details of this property will be included in the generated HTML.
" Also the MVC Music Store PDF on p 77 indicates that the attrtibute will do the same -"Allows hiding fields from editor forms".They add it to the AlbumId property and then when the app is run AlbumId field is not shown in the browser. Is this attr broken?If i change a html helper to DisplayFor it does not appear in the form regardless of whether scaffoldcolumn is present. For example i dont have scaffoldcolumn false on Property PostTitle but if i change @Html.EditorFor(Function(model) model.PostTitle) to displayfor then it does not render regardless of the scaffoldcolumn attr. Also my Create view is strongly typed to @ModelType RiderDesignMvcBlog.Core.Entities.Post?
I have an asp:checkbox control on an aspx page I am working on. This checkbox is within a custom control and previously was posting back every time it was clicked. I am in the process of ajaxifying the page and have come across a problem. When I remove the attribute AutoPostBack="True" from the asp:checkbox, the vb code returns False when I check myCheckbox.checked (this is on a postback else where on the page what has not be ajaxified), even though I can see the box is indeed checked.
I am assuming that because the checkbox no longer posts back, for some reason the VB code (or the view state maybe) doesn't see it as having been checked. Is this correct, and if so, how to I correct it?
Simple question, I have an application and dependant on whether you are in the administration system or on the public website I want to show different results. Example: in the database for a news story in the administration I may set the column value 'showonsite' to false. So I would like this to show in the administration panel only and not on the live site.
My question is, because I require the same information just with the only one column change, live site to only show true values and administration to show both. What is the most effective way of achieving this without copy paste of code?
In C# and Vb.net,is any way without iterating by loop a bitarray to check contins any true or false value (Dotnet 2.0) ?

I created a SRT program in vb6. works great. I thought it would be a good time to port it over to vb2010 for obvious compatibility issues. the following will not work, even though through debug; all the vars are correct - it just wont come up.
' Timer1.Stop() : MsgBox("start: " & CaptionStart & " end: " & CaptionEnd & " smptime: " & WMPTime) : End
If (CaptionStart <= WMPTime) And (WMPTime <= CaptionEnd) Then
txtCaption.Text = Caption
'// HIGHLIGHT IT IN THE LIST

in the above its simpler (why I like vb6) and works perfectly. I am most likely "not seeing the forest for the trees" syndrom.
