在Master母版页中路程经过过程FindControl()要领获取办事器控件 1、办事器控件与代码都位于母版页
Response.Write("<script language=javascript>window.alert('" + TextBox1.Text + "')</script>");
TextBox tb1 = (TextBox)FindControl("TextBox1");
Response.Write("<script language=javascript>window.alert('FindControl()获取：" + tb1.Text + "')</script>");
/*以下用处纰缪：
*TextBox tb2 = (TextBox)Master.FindControl("TextBox1");
*Response.Write("<script language=javascript>window.alert('" + tb2.Text + "')</script>");
*/
2、办事器控件与代码都位于内部实质意义页
Response.Write("<script language=javascript>window.alert('" + TextBox1.Text + "')</script>");
ContentPlaceHolder cpl1 = (ContentPlaceHolder)Master.FindControl("ContentPla ceHolder1");
TextBox tb1 = (TextBox)cpl1.FindControl("TextBox1");
Response.Write("<script language=javascript>window.alert('Master.FindContro l()获取：" + tb1.Text + "')</script>");
//或：
ContentPlaceHolder cpl2 = (ContentPlaceHolder)FindControl("ContentPlaceHolde r1");
//在此FindControl()代表Master.FindControl()，在Master母版页中查寻控件
TextBox tb2= (TextBox)cpl1.FindControl("TextBox1");
Response.Write("<script language=javascript>window.alert('FindControl()获取：" + tb2.Text + "')</script>");
/*以下用处纰缪：
*TextBox tb1 = (TextBox)FindControl("TextBox1");
//在此FindControl()代表Master.FindControl()，在Master母版页中查寻控件，而TextBox1在Content内部实质意义页中，以是找不到TextBox1控件
*Response.Write("<script language=javascript>window.alert('" + tb1.Text + "')</script>");
*/
3、办事器控件位于母版页，代码位于内部实质意义页
TextBox tb1 = (TextBox)Master.FindControl("TextBox1");
Response.Write("<script language=javascript>window.alert('" + tb1.Text + "')</script>");
4、办事器控件位于内部实质意义页，代码位于母版页
TextBox tb = (TextBox)ContentPlaceHolder1.FindControl("TextBox1 ");
Response.Write("<script language=javascript>window.alert('" + tb.Text + "')</script>");
/*纰缪的用处：
* Response.Write("<script language=javascript>window.alert('" + TextBox1.Text + "')</script>");
