然后在GridView的一个关于button点击的事件里
if(e.commandName=="tr")
{
Response.redirect("xxx.aspx?id=+"e.CommandArgument.ToString()"+")
}
这样就可以传值了.其他方法也类似.写到GridView里的哪个事件我具体也忘了,好像是rowCommand什么的,记不起来了,抱歉:-(
一、动态添加Button动态添加Button的效果就是点击之后,生成一个按钮,并为按钮添加点击的方法。
1、在xib文件上拖拽添加一个button,标题为:添加button。
2、按住ctrl键拖拽到addbuttonViewController.m文件空白处,生成IBAction,填充代码后如下:
[cpp] view plaincopyprint?
01.- (IBAction)addButton:(id)sender {
02.CGRect frame = CGRectMake(90, 200, 200, 60)
03.UIButton *someAddButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]
04.someAddButton.backgroundColor = [UIColor clearColor]
05.[someAddButton setTitle:@"动态添加一个按钮!" forState:UIControlStateNormal]
06.someAddButton.frame = frame
07.[someAddButton addTarget:self action:@selector(someButtonClicked) forControlEvents:UIControlEventTouchUpInside]
08.[self.view addSubview:someAddButton]
09.}
- (IBAction)addButton:(id)sender {
CGRect frame = CGRectMake(90, 200, 200, 60)
UIButton *someAddButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]
someAddButton.backgroundColor = [UIColor clearColor]
[someAddButton setTitle:@"动态添加一个按钮!" forState:UIControlStateNormal]
someAddButton.frame = frame
[someAddButton addTarget:self action:@selector(someButtonClicked) forControlEvents:UIControlEventTouchUpInside]
[self.view addSubview:someAddButton]
}
3、动态生成的button点击事件方法:
生成的button点击d出提示框。
[cpp] view plaincopyprint?
01.-(void) someButtonClicked{
02.UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
03.message:@"您点击了动态按钮!"
04. delegate:self
05. cancelButtonTitle:@"确定"
06. otherButtonTitles:nil]
07.[alert show]
08.}
-(void) someButtonClicked{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
message:@"您点击了动态按钮!"
delegate:self
cancelButtonTitle:@"确定"
otherButtonTitles:nil]
[alert show]
}
4、编译运行效果
点击按钮后
二、监听UIAlertView。
1、在上面的代码基础上,在addbuttonViewController.h文件添加委托
[cpp] view plaincopyprint?
01.#import <UIKit/UIKit.h>
02.
03.@interface addbuttonViewController : UIViewController<UIAlertViewDelegate>
04.- (IBAction)addButton:(id)sender
05.
06.@end
#import <UIKit/UIKit.h>
@interface addbuttonViewController : UIViewController<UIAlertViewDelegate>
- (IBAction)addButton:(id)sender
@end
2、在AlertView中多添加两个按钮
[cpp] view plaincopyprint?
01.-(void) someButtonClicked{
02.UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
03.message:@"您点击了动态按钮!"
04. delegate:self
05. cancelButtonTitle:@"确定"
06. otherButtonTitles:@"取消",@"第三项",nil]
07.[alert show]
08.}
-(void) someButtonClicked{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
message:@"您点击了动态按钮!"
delegate:self
cancelButtonTitle:@"确定"
otherButtonTitles:@"取消",@"第三项",nil]
[alert show]
}
效果图:
3、在对应的.m文件中实现委托中的方法
监听你点击了那个按钮
[cpp] view plaincopyprint?
01.-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
02.{
03.NSLog(@"buttonIndex:%d", buttonIndex)
04.}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"buttonIndex:%d", buttonIndex)
}点击AlertView中d出的三个按钮打印的结果:
[cpp] view plaincopyprint?
01.2012-06-14 16:53:18.516 DynamicAddButton[5645:f803] buttonIndex:1
02.2012-06-14 16:53:23.652 DynamicAddButton[5645:f803] buttonIndex:2
03.2012-06-14 16:53:25.701 DynamicAddButton[5645:f803] buttonIndex:0
04.2012-06-14 16:53:39.900 DynamicAddButton[5645:f803] buttonIndex:1
2012-06-14 16:53:18.516 DynamicAddButton[5645:f803] buttonIndex:1
2012-06-14 16:53:23.652 DynamicAddButton[5645:f803] buttonIndex:2
2012-06-14 16:53:25.701 DynamicAddButton[5645:f803] buttonIndex:0
2012-06-14 16:53:39.900 DynamicAddButton[5645:f803] buttonIndex:1
这样你就知道点了按个按钮了。
