I tried to add icons to the items in the listbox(owner drawn listbox- variable). I m able to do it. But after adding the items, according to my requirement i need to remove few items now and then.I used:Listbox1.Items.Remove("Aqua")This removes the last item from the listbox instead of the mentioned one. the same is done even if i try to remove the selected index item.
View 2 Replieshow would i go about creating an ownerdrawn dtp, with highlighted dates in the dropdown + also in the collapsed view when a highlighted date is selected? i'm guessing i'd have to inherit a dtp + then handle an event or 2. does anyone have any insight or experience with this?
View 2 RepliesOk so i have an owner drawn combobox and everything is fine in the drawitem event,except i'm a perfectionist and there is no border i have a beige backcolor, and i really just want a black border or something first i tried to draw using the given graphics and the given bounds, it failed as the rectangle was drawn oddly inside the combobox for some reason (not on the inner border, almost in the center of the combobox.then i tried the following and was surprised when it didnt work
Dim z2fx As Graphics = Graphics.FromHwnd(cmbBox.Handle)
z2fx.DrawRectangle(Pens.Black, New Rectangle(0, 0, cmbBox.Width, cmbBox.Height))
then i tried this and thought for sure it would work
1 Dim zfx As Graphics = Graphics.FromHwnd(cmbBox.Parent.Handle)
zfx.DrawRectangle(Pens.Black, cmbBox.Bounds)
this drew 2 sides of the border, the bottom and the right then i realized something: the code i used earlier with z2fx made the upper and left borders flicker right when i click the drop down, then it goes away. It is as if they were being redrawn with the background color of the combobox. And this redrawing was taking place after the drawitem event was called.
Something, some event, keeps redrawing the background color of the combobox when i put a button on the form and associate it with the zfx2 code, then when i press this button the combobox draws the 2 borders (upper and left) and they stay drawn until i either hover over the combobox or open the drop down of the combobox.
nvm while typing this i figured out a solution i can use the mouseenter mouseleave and dropdown events
since i typed this already im posting it anyway if i have problems i will let you know.EDIT: failed.SOMETHING keeps redrawing the damn background only after most events have passed! i tried the backgroundcolorchanged event it didnt work. this is annoying.
I created an image (.png) with a transparent background and I'm trying to show it in a ListView. So I added the image to the ImageList belonging to the ListView, however when drawn, there is a partial white circle around the image. I checked and rechecked the actual image and there are absolutely NO white pixels at those positions.

i have an owner drawn list box which is connected to a SQL database source. When the list box is owner drawn, my list box is filled with the text "System.Data.DataRowView". When i turn off owner drawn it works perfectly.
The problem is, i need it to be owner drawn as it is a crucial part of my program. Is there a way of keeping my owner drawn list box and preview the data from the SQL database at the same time? Here is my code for the owner drawn part, most of this is irrelevant, just mainly look at the bottom bit where i print the string, with the variable 's' and 'drawstring':[code...]
I'm trying to implement an Owner-drawn ListView in my application using the code available at this MSDN article, however I've encountered several issues.First of all, the double-click event only fires when the mouse is over the text in the first column of any ListViewItem. I'd prefer to keep the manual, timer-based, double-click detection routine as a last resort if possible.Second, when the ListView is scrolled sideways, clicking an item won't select it anymore.
View 2 RepliesI'm trying to create an owner drawn TabControl that looks like the tabs in Visual Studio on XP (might look different in Vista, not so sure).So far, I've got the background and the blueish border, and now I've run into some trouble drawing the 'tab headers' (where the text is displayed).Here's what I got so far:
vb.net
Imports System.Drawing.Drawing2D
Public Class cTabControl
#Region " Colors "

Why isn't this working? How do I draw a border like this around a 'normal' OwnerDrawn tabcontrol, without the funky SetStyle method..?also, the DoubleBuffer ControlStyle (in the SetStyles method) option is not listed in the Intellisense list, but it is accepted when I finish typing it... Is that a bug?
I have used the command:
For Each Proc as process in process.getprocesses

I have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.

View 7 RepliesSo am back again with dattagridview and comboboxes...sorry for the troubless.. Now let me come to my scenario aka problem..I have 2 dataviewgrids in my WINDOWS APPLICATION FORM (VB.net).The first grid populates some data from the SQLSERVER 2005 DB.When I click on any cell of the first grid, my second grid shows up and populates with the data corresponding to the cell which I have clicked in the grid 1.This is working perfect and so far so good.In the second grid I have 3 combobox columns and some textbox columns..The three combobox columns in this grid are also populated from the DB only usng datasets and datasource.In the first Combobox Column if I select one value, then the corresponding values are filled into the other textboxcolumns.This is also working good.The other 2 comboboxcolumns are also populated from database using different datasets..
Am about to add a master data ( i.e data into the first grid).it got added and after that a msgbox pops up sayn u must add data into the second grid as well.so the user is adding the data in the second grid.(all works except the new requirement).he added something into the first row by selecting the comboboxcolumns and also editing the other columns in the first row.(he havent saved this row.This will happen when he clicks the save button in the form not in the grid)he goes into the second row .Now here he should not see the item from the combobox1 which he has selected in row1.
