View 3 RepliesHow To Add An AddHandler Of That Newly Added Control ?
Dec 16, 2010I've been trying how to make a dynamic controls in ASP.Net and figured out that it was the same on VB.Net like this.
Code:
Dim objCheck As New Checkbox
With objCheck
.Name = ""
The only difference is that instead of "Name" that should be "ID" and "Location" should be "Attribute("style") = "top:100px; left:100px".
Now I'm getting this error saying that "it should be place in a form tag and runat="server"".
BTW, that adding of dynamic controls is place in Page_Load()
Secondly how to add an AddHandler of that newly added control ?
VB.NET AddHandler Throwing Object Reference Not Set?
Mar 5, 2010I have an ASP.NET page with code-behind in VB.NET. On the ASPX page I have a Repeater with an asp:ImageButton inside the repeater and I want to catch the clicks on the button. As far as I read I have to use FindControl and then handle the copy of the original control:
Codebehind:
Dim imagebutton1 As ImageButton = repeater.FindControl("btnImage1")
AddHandler imagebutton1.Command, AddressOf ReportTransfer
...
...
Protected Sub ReportTransfer(ByVal sender As ImageButton, ByVal args As CommandEventArgs)
...
End Sub
ASPX page:
<td>
<asp:ImageButton runat="server" ID="btnImage1" ImageUrl="~/images/icons/icon_small.png"
CommandArgument="3" />
</td>
</tr>
</ItemTemplate>
It throws "Object reference not set to an instance of an object" on the AddHandler line and I have no idea why it is doing it (I'm a bit new with VB.NET)

Web Forms :: How To Use AddHandler To Dynamically Assign Events To Dynamically Created Buttons
Feb 14, 2011I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
Addhandler Causes 'Error Creating Control - MainContent' Error In Design View?

View 1 RepliesC# - Can Convert To The String But Can't Convert Back
Jul 30, 2010I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.

I'm going to generate the 8.5" x 11" BMP in Flash (which means I can manipulate it to make it as easy as possible), then use a POST to upload it to an ASP page, which will convert it to a PDF and redirect the user to the PDF. I don't want to add any margins or anything else, it will be laid out properly in the BMP for full-bleed.Would it be easier to convert it to PDF in Flash, then upload?
