如何验证直放站中的空白文本框? [英] how to Validating blank textbox in repeater?

问题描述

大家好

在我的项目中，我需要进行验证工作:

我有一个中继器(.net 2.0，C#，VS 2k5)，在此中继器中
有一列文本框，
一列Button，用于编辑文本框的值，
和Checkbox的一列，用于分配选择行
站点中继器具有一个按钮，当我单击此按钮时，复选框选中的所有行都将在数据库中更新
我必须要做的是如何选择行将不会更新，并在包含空白文本框的行上引发验证，请重点关注空白文本框
请帮助我.非常感谢

推荐答案

您可以在ELSE-part中这样编写.

you may code like this in ELSE-part.

TextBox T = (((TextBox)items.FindControl("txtsno"))
T.Focus();
Page.RegisterStartupScript("Errorlog", "<script>alert(\"Text Value is Missing\");</script>");
// you may also use following to make it easily visible.
T.BorderColor = System.Drawing.Color.Red;
return;

对于THEN部分
将id值保存在数组中.

For the THEN-part
keep the id values in a array.

ArrayList ids = new ArraList();
ids.Add(oid);
.
.
.

遍历Arraylist并在调用函数之前进行处理.

Loop through the Arraylist and process before call to function.

LoadData();
