hi,
it seem that you are binding two different types to a single combobox.
first you bind the "tmpTable" with the columns "ProductKeyword" and "PortalProductMasterID" then you bind an object "Keyword". but from the code you provided, i don't see any similarity between the two - "tmpTable" and "Keyword". your existing "Keyword" class doesn't contain the properties you are trying to bind. what you should do is make the class "Keyword" comparable to the table you are trying to bind, i.e. add the properties "ProductKeyword" and "PortalProductMasterID" to you existing class - "Keyword".
hope this helps

Hello smyer,
First you made your own scrolling listbox using this code :
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.ComponentModel;
using System.Runtime.InteropServices;
namespace myscrollList
{
class scrollList : System.Windows.Forms.ListBox
{
[Category("Action")]
//public event ScrollEventHandler Scroll = null;
private const int WM_HSCROLL = 0x114;
private const int WM_VSCROLL = 0x115;
public event ScrollEventHandler OnHorizontalScroll;
public event ScrollEventHandler OnVerticalScroll;
private const int SB_LINEUP = 0;
private const int SB_LINELEFT = 0;
private const int SB_LINEDOWN = 1;
private const int SB_LINERIGHT = 1;
private const int SB_PAGEUP = 2;
private const int SB_PAGELEFT = 2;
private const int SB_PAGEDOWN = 3;
private const int SB_PAGERIGHT = 3;
private const int SB_THUMBPOSITION = 4;
private const int SB_THUMBTRACK = 5;
private const int SB_PAGETOP = 6;
private const int SB_LEFT = 6;
private const int SB_PAGEBOTTOM = 7;
private const int SB_RIGHT = 7;
private const int SB_ENDSCROLL = 8;
private const int SIF_TRACKPOS = 0x10;
private const int SIF_RANGE = 0x1;
private const int SIF_POS = 0x4;
private const int SIF_PAGE = 0x2;
private const int SIF_ALL = SIF_RANGE | SIF_PAGE | SIF_POS | SIF_TRACKPOS;
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetScrollInfo(
IntPtr hWnd, int n, ref ScrollInfoStruct lpScrollInfo);
private struct ScrollInfoStruct
{
public int cbSize;
public int fMask;
public int nMin;
public int nMax;
public int nPage;
public int nPos;
public int nTrackPos;
}
protected override void WndProc(ref System.Windows.Forms.Message msg)
{
if (msg.Msg == WM_HSCROLL)
{
if (OnHorizontalScroll != null)
{
ScrollInfoStruct si = new ScrollInfoStruct();
si.fMask = SIF_ALL;
si.cbSize = Marshal.SizeOf(si);
GetScrollInfo(msg.HWnd, 0, ref si);
if (msg.WParam.ToInt32() == SB_ENDSCROLL)
{
ScrollEventArgs sargs = new ScrollEventArgs(
ScrollEventType.EndScroll,
si.nPos);
OnHorizontalScroll(this, sargs);
}
}
}
if (msg.Msg == WM_VSCROLL)
{
if (OnVerticalScroll != null)
{
ScrollInfoStruct si = new ScrollInfoStruct();
si.fMask = SIF_ALL;
si.cbSize = Marshal.SizeOf(si);
GetScrollInfo(msg.HWnd, 0, ref si);
if (msg.WParam.ToInt32() == SB_ENDSCROLL)
{
ScrollEventArgs sargs = new ScrollEventArgs(
ScrollEventType.EndScroll,
si.nPos);
OnVerticalScroll(this, sargs);
}
}
}
base.WndProc(ref msg);
}
private void InitializeComponent()
{
this.SuspendLayout();
//
// scrolled
//
this.Size = new System.Drawing.Size(120, 95);
this.ResumeLayout(false);
}
}
}
After this .........
Drag your listbox on windows forms and than sync two listbox together using this.......
private void scrollList1_OnVerticalScroll(object sender, ScrollEventArgs e)
{
scrollList2.TopIndex = scrollList1.TopIndex;
}
private void scrollList2_OnVerticalScroll(object sender, ScrollEventArgs e)
{
scrollList1.TopIndex = scrollList2.TopIndex;
}
I hope this will work..........

Hi There,
I'm having some trouble with CheckedListBoxes in my application. The application is written in C# in .NET 1.1. It's multi-tabbed, and on each tab there is an instance of my user control, which contains 6 combo's and 6 CheckedListBoxes.
The control works fine when you stay on a single tab, however when I switch tab and come back again, all the CheckedListBoxes still have their data, but they lose the CheckedItems collection, so they are all unchecked.
Has anyone come across this problem?
Thanks in advance,

Jim,
(I could wait til you get back from lunch.. but I think the code project needs to know as well  )
I found the problem, its a known bug in .NET 1.1.
Documented here: http://support.microsoft.com/kb/833033
The problem only occurs when the checked list box is bound to a data table.
It looks like Microsoft's only solution is to maintain a collection of checked items and refill on tab switch (rubbish!). But I guess that is what we're going to have to do...
Rob.

Thanks ,

Regsvr32 only works with COM DLLs. If it can't find DllRegisterServer then it isn't a COM DLL and doesn't need to be registered.

No control does this, but it's easy enough to write one. Just set up a control that contains the text, and keeps drawing itself scrolling, then capture the click event, work out what's been clicked, and then based on that, open another form.

i am creating an admin section of Media Schedular Application which shows schedules in schedule controls in detail section and the header contains a ruler bar to show the scale in minutes. this schedular shows records for one month and of all four quarters of screen.
i have two panel controls named pnlHeader (no scroll bars) and pnlDetail (both vertical and horizontal scroll bars). when a user scrolls vertically up and down on pnlDetail, there is no effect on pnlHeader but when user will scroll horizontly on pnlDetail the other panel named pnlHeader will also scroll accordingly.

Hi there,
I'm trying to create a class of combo box that allows users to select from a list of filter otpions. In the class declaration I have the following:
...
public filterTypeComboBox()
: base()
{
DataSource = null;
this.Items.Add("= (equals)");
this.Items.Add("<> (not equal)");
this.Items.Add("<= (less than or equal to)");
this.Items.Add("< (less than)");
...
}
...
When I add an instance of the filter combo it duplicates the list of items. Any ideas how to prevent this, or more importantly why this happens? (As a temporary workaround I have commented out the duplicates in the designer).
Thanks
Paul

in First line U Call the
this.items.clear()
|
|
|
|
|
Curiouser and curiouser...
that seemed to do the trick, at least partially as the designer code now reads:
...
this.m_FilterTypeComboBox1.Items.AddRange(new object[] {
"= (equals)",
"<> (not equal)",
...
"begins with",
"ends with"});
...
However, this is quite strange, when I run the form the combo box lists exactly 2 set of the list when I scroll down using the thumb, however when I scroll using the arrow it only scrolls through 1 set. ie
The combo box items are:
= (equals)
<> (not equal)
...
begins with
ends with
= (equals)
<> (not equal)
...
begins with
ends with
but when I press the down arrow to cycle through the options it gets to ends with and the next item is back to the top of the list.
I'm stumped!
Thanks,
Paul
