1.模态窗口的打开

2.模态窗口的关闭

3.模态窗口的传递参数。

4.其他。。。。

1.window.showModalDialog("DialogPage.aspx","newwin","dialogHeight: 200px; dialogWidth: 150px; dialogTop: 458px; dialogLeft: 166px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;");

2.window.close();

3.传值

ParentPage.aspx:

window.showModalDialog("DialogPage.aspx?para1=aaa&para2=bbb");

DialogPage.aspx:

string str1=Request.QueryString["para1"].toString();

string str2=Request.QueryString["para2"].toString();

返回值

DialogPage.aspx:

window.returnValue="aaa";

ParentPage.aspx:

var str=window.showModalDialog("DialogPage.aspx");

4.

aspx页面在showmodeldialog情况下为什么一提交就重新打开一个页面?

showmodaldialog打开的页面中在<head></head>之间加入一行:<base target="_self">



5.如果是在数据绑定的模式窗体中,还可以在DataGrid中创建一个模板列,再加入Html的按钮,在按钮中加入:

OnClick="returnValue='<%#DataBind.Eval(Container.DataItem,"Name")%>';window.close()"

就可以实现在模式对话框中传递DataGrid的具体选中的行的相关值。
