动态创建的文本框不更新 [英] Dynamically created textboxes not updating

问题描述

i有asp.net web应用程序，其中我用来生成文本框列表依赖于表中的count.owever每当我加载细节我得到相同的输出每次都是TextBox。



请帮忙。



我尝试过：



生成所有控件后（TextBox，下拉列表等）我在下面这样做



TextBox txtRes1 =（TextBox）PlaceHolder1.FindControl（id1）;

txtRes1.Text = concat（value1，valu2）;



public int concat（strin v1，string v2）

{

return v1 + v2;

}

Hi,
i have asp.net web application in which i used to generate list of text boxes depend on count in table dynamically.however whenever I load the details I am getting the same output in the TextBox every time.

please help.

What I have tried:

after generating all controls(TextBox,dropdownlist etc) i am doing this below

TextBox txtRes1 = (TextBox)PlaceHolder1.FindControl("id1");
txtRes1.Text= concat(value1, valu2);

public int concat(strin v1, string v2)
{
return v1+v2;
}

推荐答案

Thanks guys.
i got the solution for this by creating a TextChanged event of a textbox in which i wanted to put the new changed value.

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
string endDate = Request.Form[((TextBox)PlaceHolder1.FindControl("tb1")).UniqueID];
                                    string startDate = Request.Form[((TextBox)PlaceHolder1.FindControl("tb2")).UniqueID];

TextBox txtRes = (TextBox)PlaceHolder1.FindControl("tb31");
txtRes.Text = tbc.DateDiff(Convert.ToDateTime(endDate), Convert.ToDateTime(startDate));
}
