CheckBox控件在GridView中不起作用... [英] CheckBox control is not working in GridView...

问题描述

protected void Button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < GridView1.Rows.Count;i++ )
        {
            CheckBox chk = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1") as CheckBox;
        }
    }

我无法选中复选框'的值......如果选中复选框，则意味着在点击删除按钮后删除了该特定行...





任何人请帮助

推荐答案

foreach(GridViewRow row in GridView1.Rows)
{
    CheckBox chk = (CheckBox)row.FindControl("CheckBox1");
    if(chk.Checked)
    {
         // code here
    }
}

当你已经将控件转换为复选框时，为什么使用as关键字？



尝试：

CheckBox chk = new CheckBox ;

chk =（CheckBox）GridView1.Rows [i] .FindControl（CheckBox1）;



而不是：

CheckBox chk =（CheckBox）GridView1.Rows [i] .FindControl（" CheckBox1"）作为CheckBox;

Why are you using "as" keyword when you are already casting your control as checkbox?

Try:
CheckBox chk = new CheckBox;
chk = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");

instead of:
CheckBox chk = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1") as CheckBox;
