Validator Summary Will Not Update Dynamically
May 17, 2011
I have a validation Summary I am using for the RequiredFieldValidators to use to show the error messages while an image shows up next to the controls being validated.I have set the required field validator to Display="Dynamic". When I select something in the dropdown it removes the image next to the control right away like I want but the errormessage text stays on the ValidatorSummary.What can I do to make the ValidatorSummary to update dynamically like the RequiredFieldValidator when it removes the image next to the dropdown?

I am trying to update my form once the delete button is clicked. There are several fields like Name, Date, Date of Birth and so on. Once I delete record I want the form to automatically load with new / updated data. This form fetches data from MS Access using OLEDB. Once when I close the application and reopen then form will be updated with new values. But I want this to happen once the form loads after deleting.[code]

I have written a Type Converter for a TrackBar. I was wondering if there is any way to get the value being changed in the Dropdown so I can update the PropertyGrid item value dynamically instead of just at the end?
Here is the Type Converter code:
Code:Imports System.Windows.Forms.Design
Public Class Slider
Private editorService As IWindowsFormsEditorService
Private m_Value As Integer
[Code]...

i have a pretty standard crystal report that shows a quote for materials for various customers - i also have a form, lets call it form1 for arguments sake - on form 1 i have two data grid views - one attaches to the customer table, one attaches to the quote table. Customer and quotes are linked on customer number at the database level.
i dragged and dropped these on to the form and they work great, as i scroll through each customer in the customer datagridview, that customer's respective quotes show up in the quotes datagridview.
now the problem - as a third tier, i have a crystalreportviewer that has all the nice graphics and presentation of this quote, company logo, etc etc, i've also done all the standard report sources etc etc, but the darn thing won't cycle through the quotes as i scroll through them in the quotes datagridview.
am i missing something simple? all i want to do is highlight "abc company", see their list of 50 different quotes pop up in the quotes datagrid view, then click a quote number and see the quote display in the fancy smanshy crystal report viewer so i can then print or export or whatever.

I am creating an information access system. Here the notifications created by the admin will be visible to the user through a visual basic form and sql database. I need a maximum of 20 notifications and the last created notification should appear at the top in the form. Also when the 21st notification is created it should automatically delete the 1st and so on.

I have several group boxes on a winform. within each there are several labels.I am accessing the group boxes with no issues but I can't seem to find a way to update the labels within by looping. They have the same name except the last character which is a number 1 - 9. ex. lbl1, lbl2 ... lbl9.I need to update the text of each label in code with text I get from a database ex. lbl1.text = one, lbl2.text = two etc... I want to loop through the labels to assign the text. Getting text from database is no issue what I am not doing properly is getting the labels.
do while QstNum < 10
Dim ln As New Label
ln.Name = "SC_Cat" & QstNum

I want to use a validator to compare 2 text box in such a way that ,
If V is in Text box 1, means User must type any of the numbers prefix V in Textbox 2 (V00001 to V00050).Other than V ,if they type any other Letters means error message must be shown.
Just like that if C is in TextBox 1 means user must type C00001 in TextBox2.(or any number from C00001 TO C00050) iF S is in textbox 1 means,User must Type S00001(S00001 TO S00050)

I have been using the method summary XML Comments at the top of my procedures lately and am wondering if there are any logical or good practices related to this.I never put anything in the remarks because I put the description of the method in the summary tag. What belongs in the summary and what belongs in remarks?I seldom put anything in the returns tag because it seems like it would be redundant as I usually explain what is being returned in the summary. Should I simply keep the type of object returned in the returns tag?
