I would like to create a multicolumn list of items, similar to the right pane of the Windows Explorer window. There are rows, one for each item. And there are columns similar to the filename, size, date of last modification, etc. columns of Windows Explorer. The data supplied to the control will be individually extracted from files. (I mean, no database, no spreadsheet is available as a source.)
Question: Which control is the best for this purpose? I tried listbox, but it seems "multicolumn" means not what I'm used to in Excel VBA.
I have took a little research, but I couldn't find the answer. I am looking for code that when I input the textbox something like in the first letter "a,b,c,d,e or whatever it goes", find the match of the listview items that come with the same text property of the textbox while hide the unmatched listview items.
However, I used this:
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Dim i As Integer

View 2 RepliesI have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
In a user control I have the code shown below.
I now realize that it is incorrect because the container's InitializeComponent property initializations have not run yet and they must be run prior to Refresh being called.
How (where) can I run Refreash after the container has initialized this user control.[cod]e...

I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.

View 2 RepliesI am running VS2008 and developing a Windows Form App in VB.Net. Is there not a bound multicolumn combobox like Access has had forever? If there is one buried in VS2008, the Windows OS or MPF 2010 or somewhere else would you mind sharing? I could hardly believe my eyes when I did not see one in the common controls list.
Not knowing the correct terminology, I would like this control to be a tool component that I can drag onto my form and set the binding and column properties and be done with it.Come on Microsoft VB.Net Dev Team... where have you been on this? This type of control has been out for umpteen years in Access and 3rd party took kits. There is nothing that says Rapid development like roll your own code! I have seen serveral articles on how it can coded;?
Is there a dll somewhere or some place I can read a good example on how to add data from a datatable into a multicolumn combobox? Preferably to be able to stick a datagridview right into the combobox would be awesome.

However, I am now in a tough spot because I need to find and remove duplicates from a multicolumn list view. I tried using LINQ but it says that the listview object is not "queryable". Is there a way for me to find and remove duplicates using only one column of the listview? [code]The code now runs fine when I call it. But it does not remove the duplicates:

I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!

View 10 RepliesI tried it and get an error but maybe I'm tring the wrong way. Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.
