The dock is fill.
and anchor is top and left.
I saw that if I set the parameter in an event such SelectedIndexChange it works.
but I feel that is wrong to do such a thing (and also it doesn't cover all the cases)
any other guess?

Thanks.

handle related index change event and always keep track of previous index in some location. In this way you will always have a valid old index saved and before updating it to newer index you can make use of it.

Based on the Wikipedia definition of TCP Window Scale Option[^], it seems you don't achieve it at the application level.

label is not becoming visible

Hi,

I have a panel on a windows form.
In the panel, I have a label, I have set the visible property of the label as False in design time.
now at runtime, in a function I am trying to make label visible like this,
label1.visible = true;

but the label1.visible property does not change, it still has false value, but once the form executes completely, label becomes visible, I cannot understand, How this is happening.

can someone tell me that why the label1.visible property does not become true, when I explicitly assign true to it.

Thanks in advance,

Regards
Mahesh

It sounds like you are running a process that is holding up the UI, basically the form is not being refreshed until the process is complete. Adding the following line after settings the visible property of the label to true should work..

label1.Visible = true;
form1.Refresh();

Life goes very fast. Tomorrow, today is already yesterday.

What do you mean by this?

If you are calling a function which takes a long time to exexute and you are changing the property inside that than it will only appear after the task.
You may look at Backgroundworker to prevent this.

Welcome to the wonderfull world of visible!!

This is a really good example of stupidness within the framework. The setter flags that you <want the="" control="" <i="">to be visible. The getter reports if the control is visible. The two are not the same, you can also see the same behaviour with enabled.

c# adding events to programmaticlly added controls

So the situation is the folowing

Inside a tabview control; i add programaticly a number of tabs (the number is not fixed); on each tab i add a listview. My question is how do i add an event item so that when i click any item from any list i fill a textbox with something from that item; my code looks like this

public void lv_SelectedIndexChanged(object sender, EventArgs e)
        {
         while (n!=0)
         {TabPage tp=new TabPage();
         tabControl1.TabPages.Add(tp); 
         
         ListView lv = new ListView();
         //setting som properties here and filling the list
         tabControl1.TabPages[k].Controls.Add(lv);
         n--;
        }
}

I've written just a portion of the code.Help will be apreciated.Thank you in advance.
Alex.

Immediately after creating the new listview instance, subscribe to the desired event.

Hi,

not exactly sure what you want. Here are three pointers:

1.
you can program anything by code that you also could do interactively in Visual Designer; all VD does is add code in some file (myForm.designer.cs), there is no magic involved; look at such code, and do the same thing in the appropriate method yourself.

2.
you can share event handlers across multiple controls; all event handlers have a first argument object sender that serves to identify the exact sender of the event; you would probably have to cast it to the appropriate control type first.

3.
you may find it useful to somehow make one Control (say ListView) refer to another Control (say TabPage); every Control has a object Tag property that serves no particular purpose, so you can store anything you like there, and use it where useful. As an alternative you could create a map using a Dictionary.

Smile | :)

It's purpose has always been to provide User-defined data associated with the object. I think it should be programmer-defined, but hey ho.
