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

I want to add a new PropertyGrid control every time an item is added to a ListBox.I have a ListBox, with an "Add Item" button underneath (and also a "Remove Item" button). Every time an item is added to the list, I want to create a new PropertyGrid corresponding to each item. The relevent PropertyGrid should appear when an item is selected in the ListBox, and the user can edit the properties of that item.
The only way I can think of doing this is by creating a dynamic array which has length ListBox1.items.count, but I'm not sure it's possible to create an array of controls.

View 1 RepliesI 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 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.

View 1 RepliesI 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.

I'm having an issue wherein after I run a search filtering a datagrid, the corresponding datadetails will not update anymore when a new item is selected in the datagrid.I would like it so after clicking an item in the datagrid, the details update automatically.
[URL] The problem is, after running a search (or hitting 'show all') the label/details no longer change when selecting a new item in the datagrid.[URL]
Private Sub Sheet1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.Validate()
Me.Sheet1BindingSource.EndEdit()
[code]....
To clarify, the search itself filters the datagrid perfectly as intended....it just seems to stop the details from updating when new items are selected which is my problem.
