GridView中使用CheckBox

asp.net中checkbox是向服务器提交时才能触发事件

把该控件的autopostback设置为true，才能响应事件

protected
void Checkbox_CheckedChanged1(object sender, EventArgs e)

{

string id = string.Empty;

foreach (GridViewRow gr in this.newsTable.Rows)

{

CheckBox CB = (CheckBox)gr.FindControl("ChkItem");

if (CB.Checked)

{

id += this.newsTable.DataKeys[gr.RowIndex]["InfoTableOID"].ToString();

}

}

this.hidden.Value = id;

}
