loop through the items and compare the text value - select the item and bail out of the loop.
If you are binding use the same field for the DisplayMember and the ValueMember

Hi All,
I want to do a process on specific tab. So I do similar to this.
private void AllTabs_SelectedIndexChanged(object sender, System.EventArgs e)<br />
{<br />
if(AllTabs.SelectedTab == tabMyTab)<br />
MessageBox.Show("FOUND");<br />
}
On click the specific tab, message is pop-up. But the issue is, message also pop-up on the form load as well. I don't want to do that. Can someone help me to sort out this.
Thanks a lot 
I appreciate your help all the time...

Create a form level bool
bLoading = true;
In your selected indexchange event do the following as you first line of code
if(bloading)
{return;}
the last thing in the form load method set bLoading to false

Hi,
You can remove the Events from the AllTabs while loading and add back it again.
To remove an event.
AllTabs.SelectedIndexChanged -= new ...........

Hi all,
I can not retrive the elements from a hashtable in the same order as they are added.
please help......
Hashtable htParameters = new Hashtable();
htParameters.Add("fromDate", string.Format("'{0}'",fromDate.ToString("dd-MMM-yyyy")));
htParameters.Add("ToDate", string.Format("'{0}'",toDate.ToString("dd-MMM-yyyy")));
htParameters.Add("dtOvdDate", string.Format("'{0}'",dtOvdDate.ToString("dd-MMM-yyyy")));
htParameters.Add("dtOvdDatePrev", string.Format("'{0}'",dtOvdDatePrev.ToString("dd-MMM-yyyy")));
htParameters.Add("strAndPaid", string.Format("'{0}'",strAndPaid));
htParameters.Add("rdoFileInfoSpecific", string.Format("{0}",rdoFileInfoSpecific.Checked?"1":"0"));
htParameters.Add("SpecificFileNo", string.Format("'{0}'",txtFileInfoSpecific.Text.Trim()));
htParameters.Add("strAndFOfficer", string.Format("'{0}'",strAndFOfficer));
htParameters.Add("strAndZone", string.Format("'{0}'",strAndZone));
htParameters.Add("strCollType", string.Format("'{0}'",strCollType));
htParameters.Add("rdoStatusNID", string.Format("{0}",rdoStatusNID.Checked?"1":"0"));
htParameters.Add("rdoStatusBankOpen", string.Format("{0}",rdoStatusBankOpen.Checked?"1":"0"));
htParameters.Add("chkOvdVal", string.Format("{0}","0"));
htParameters.Add("rdoRepTypeAllDet", string.Format("{0}",rdoRepTypeAllDet.Checked?"1":"0"));
when retrieving.....
they comes in different order
if (parameters != null && parameters.Count > 0)
{
foreach (string parametername in parameters.Keys)
{
SqlParameter param = new SqlParameter("@" + parametername, parameters[parametername]);
Cmnd.Parameters.Add(param);
}
}
plz reply asap

This is in the nature of the hashtable. all elements are sorted by the hash of the key as mention here:
http://msdn.microsoft.com/en-us/library/system.collections.hashtable.aspx[^]
"Represents a collection of key/value pairs that are organized based on the hash code of the key."
Use List< KeyValuePair< T,T > > for that unless you need an efficient by-key retrieval
And please post code that compiles for others, like keep consistent field names (what is parameters?) and post code that works without rewriting all of your format variables.

I can give the rectangle of a control by bounds.but I don't know how get the visble rectangle when a control not display whole.
Rectangle r = ctrl.Bounds;
ctrl.DisplayRectangle;

What do you mean by not displayed whole?
Windows keeps track of what parts of a control need to be repainted and joins them together into a 'clip rectangle' which is passed the the OnPaint handler.

Thanks!
I have two container controls like follow "a" and "b"
┌────┐
｜ ｜
｜ a ｜
｜ ｜
└────┘
┌───────┐
｜ ｜
｜ b ｜
｜ ｜
└───────┘
b is bigger than a
And I drag b into a,so b only display the visible area and I want to get that,not b.bounds
┌────┐
｜ a┌──┤
｜ ｜ ｜
｜ ｜ b ｜
└─┴──┘
how can I get it?
|
|
|
|
|
Ok,I get it,follow
ctrlP = ctrl.Parent;
Rectangle r = ctrl.Bounds;
Rectangle rP = new Rectangle(0, 0, ctrlP.Width, ctrlP.Height);
r.Intersect(rP);
but I have new issue,I want to draw the border of the "display bound"
Graphics g = ctrlP.CreateGraphics();
Pen p = new Pen(Color.Red);
p.Width = 1.5f;
g.DrawRectangle(p, r);
g.Dispose();
It draw the top and the left line fine,but the right and the bottom line were clear,because OnPaint event of ctrl?
and this method was fired in Form_Paint(object sender, PaintEventArgs e).
|

Yup, that looks good using the intersection of the two rectangles. The right and bottom line are probably not appearing because they're outside the clip rectangle. The Rectangle method draws a rectangle where the dimensions you supply are the area inside and not including the lines.
Try deflate()ing the rectangle a bit and you should see all four sides.

Rob Philpott.

I use the Inflate(-2, -2) to make sure the Rectangle was inside the clip rectangle,but they're still not appearing.

I think the cause is the graphics,which belong to panel1(the parent of groupbox1),we drawed the rectangle on the panel1 but it just under the groupbox1.So the rectangle we drawed were cover by the groupbox1.
|
|
|
|

I'm not sure I like the look of this. You appear to be painting on the groupbox in the paint event of the form. Really you should only use that to paint areas of the form that don't have controls on them. You'd need to do that paint in the groupbox's paint event, not the form one.
Likelyhood is that the groupbox paints itself immediately after the form. Do you get flicker at all?

Rob Philpott.

change the p.Width = 1.5f; to p.Width = 10f;
you can see the left and top line were drawed.

...f is a Form
Control t_ctrl;
for (int i = 0; i < f.Controls.Count; i++)
{
t_ctrl = f.Controls[i];
TreeNode t_tn = new TreeNode(string.IsNullOrEmpty(t_ctrl.Text) ? t_ctrl.Name : t_ctrl.Text);
t_tn.Tag = t_ctrl;
self.treeView1.Nodes.Add(t_tn);
addNode(t_ctrl, t_tn);
}
...
private static void addNode(Control ctrl, TreeNode tn)
{
Control t_ctrl;
for (int i = 0; i < ctrl.Controls.Count; i++)
{
t_ctrl = ctrl.Controls[i];
TreeNode t_tn = new TreeNode(string.IsNullOrEmpty(t_ctrl.Text) ? t_ctrl.Name : t_ctrl.Text);
t_tn.Tag = t_ctrl;
tn.Nodes.Add(t_tn);
if (t_ctrl.Controls.Count != 0)
{ addNode(t_ctrl, t_tn); }
}
}
but is not full,some controls not got into the treeview1.such as ToolStripMenuItem.
somebody can give me some tips or advises.Thanks!

You should use a foreach, and you should write a recursive method, because some controls, contain controls.

Thanks for your reply
I had already use the recursive method-->"addNode(Control ctrl, TreeNode tn)"
|

Controls inside a tool strip aren't available from the Controls property, you need to use the Items property instead.
|
|
|
|
|
So if I want to make it, I need to consider all those special controls,
It's not a easy thing,right?
Did anybody have idea about how display all controls in winfroms at runtime like vs2005 doc outline tool in designtime?
