A few lines of code with c # drawer navigation menu-CodePudding

Amateur FoxPro learned for several years, never contact with c #, this several days on a whim, want to make a drawer in the c # navigation menu, but dazed by control attributes of the Dock, after some fumbling finally succeeded, of course, this is just a prototype, beginners can see, also please everybody MoXiao words, and can put forward improvements, thank you!
A, preparation:
1, a panel control, named panel1;
2, the number of a button control, named for the respectively, button2, button3... , all height of 25 ( important! Must be set to the same height! ), TabIndex attribute respectively 0,1,2,3 ( is very important! Must start from 0 sequentially increasing , as to why, you naturally understand behind), adjust the layout, as shown in figure 1:
3, open the form Designer. Cs, from top to bottom to modify as you want to order, such as for button2, button3,... And so on ( is very important! Order from top to bottom to be exactly the same as that of the layout of the figure a, can't reverse , as to why, you look at the controls of the Dock property will understand), as shown in figure 2:

Second, in a button control in the Click event to write down the following code:
Int myHeight=25;//assume that the Button height is 25, can be defined by oneself, but all with demanding
Int myIndex=this. Panel1. Controls. IndexOf ((Button) sender);//get the current control index
Foreach (Control myButton in this. Panel1. Controls)//traverse all Controls
{
If (myButton TabIndex & lt;=myIndex)
{
MyButton. The Dock=DockStyle. None;//remove the Dock first attribute (this step is very important)
MyButton. Top=myButton. TabIndex * myHeight;//to redefine the Top value
}
The else
{
MyButton. The Dock=DockStyle. Bottom;//set the Dock property: down
}
}

dishes, so don't recommend,

Friend, any player from rookie, no people are born to understand! I learn c # 3 days, it is the amateur, natural not you very well, the real master is always modest, you never know tomorrow or the day after tomorrow, let you does eye before a few streets rookie will jilt you! If you think that the code is not good, you can write a better to share,
