我在页面上有一个按钮,当用户单击该按钮时,我需要遍历 GridView 中的每一行,然后找到复选框,然后我需要检查复选框是否被选中.如果复选框被选中,我需要将标签模板字段中的值添加到数据库中的不同表中.我正在使用 C# 代码.非常感谢任何帮助,提前致谢!
I have a button on the page which when the user clicks the button I need to loop through each row in the GridView, then find the CheckBox then I need to check if the checkbox is checked or not. If the checkbox is checked I need to add the value in the Label Template Field to a different table in the database. I am using C# Code. Any help is much appreciated, thanks in advance!
推荐答案
Loop like
foreach (GridViewRow row in grid.Rows)
{
if (((CheckBox)row.FindControl("chkboxid")).Checked)
{
//read the label
}
}
