Can you help me, how to make function download file base selected checkbox in gridview?

If is select one checkbox and i press button download so i will download one file base checkbox selected, and if i select two checkbox and press button download, i will download two file base checkbox selected.

Help me please, thankyou.

您可以执行以下代码之类的操作。如果你有很多可以通过Text或Tag属性轻松区分的复选框,它会很好用。



You can do something like the code below. It works well if you have a lot of check boxes that can easily be distinguished via the Text or Tag properties.

private void buttonDownload_Click(object sender, EventArgs e)
{
    foreach (Control ctrl in this.Controls) // this = the form
    {
        CheckBox chk = (ctrl as CheckBox);  // Only care about checkbox controls
        if (chk != null)
        {
            if (chk.Checked)
            {
                string text = chk.Text;     // Can be used to select download action
                // Do your stuff
            }
        }
    }
}



由于我不知道您要下载什么或者您的复选框如何,我无法提供更具体的解决方案。


As I don't know what you want to download or how your check boxes look like, I cannot give a more specific solution.
