问题描述
大家好，
我在转发器中有一个复选框，
当用户选中该框时会保存这些值，
但是在代码中，当我把它放在循环中时......复选框值变为false。

bool twenty = rb2.Checked;
HiddenField hdn = (HiddenField)item.FindControl("hdnChemical");
int ChemicalID = Convert.ToInt32(hdn.Value);
TextBox rows = (TextBox)item.FindControl("txtrows");

我不知道关于web
但是我在Windows应用程序中遇到了Datagridview这个问题。
为此我实现了dataGridView1的CurrentCellDirtyStateChanged事件。
希望这可以帮到你：
I don't know about web
But I encountered with this issue in windows application for Datagridview.
For this I have implemented CurrentCellDirtyStateChanged event of dataGridView1.
Hope this may help u:
private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
