如何将两个变量绑定到LinkBut​​ton控件 [英] How to Bind Two Variables to LinkButton Control

问题描述

我有链接按钮，并想使用参数
动态设置相同的postbackurl属性 例如〜profile/home.aspx?param = 4"

为此，我有数据源包含两列
1)ID
2)重定向路径

现在我必须将这两个列的值连接起来以像上面给出的那样形成url

我正在尝试

PostBackUrl =''<％#Bind("RedirectPath")?param =" Eval("ID")％>''

但它不起作用

I have link button & want to set postbackurl property of the same dynamically with parameter
eg "~profile/home.aspx?param=4"

for this i have datasource contain two columns
1) ID
2) Redirect path

now i have to concatenate this two column value to form url like the give above

i m trying this

PostBackUrl=''<%# Bind("RedirectPath") "?param=" Eval("ID") %>''

but its not working

推荐答案

请使用双引号"而不是字符串"括起来，如果变量PostBackUrl是字符串以外的其他类型，则将其转换为字符串.

字符只能容纳一个字符，字符文字是单引号中的单个字符，即&"，如果我们包含多个字符，则会产生错误字符文字中的字符太多"

谢谢，

Please enclose in double Quotes "" instead of character string '''' and convert it to string if variable PostBackUrl is another type other than string.

A char can hold a single character only, a character literal is a single character in single quote, i.e. ''&'' , if we enclose more than 1 character then it will generate error "too many characters in character literal"

Thanks,

您还可以做一件事，您可以在sql select查询中选择两列作为单列.

You can do one more things, u can select two column as a single column in sql select query.

SELECT (ColumnA + ColumnB) AS ColumnZ
FROM Table;

然后将其与单个控件绑定

and then bind it with single control
