我的尝试：
How to find a Particular grid column to click on checkbox????
foreach (GridViewRow grow in gdvheader.Rows)
{
CheckBox chknav = (CheckBox)grow.FindControl("chksyncnav");
if (chknav.Checked)
{
int id = Convert.ToInt32(grow.Cells[1].Text);
}
}
What I have tried:
foreach (GridViewRow grow in gdvheader.Rows)
{
CheckBox chknav = (CheckBox)grow.FindControl("chksyncnav");
if (chknav.Checked)
{
int id = Convert.ToInt32(grow.Cells[1].Text);
}
}推荐答案
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="CheckBox1_CheckedChanged" />
</HeaderTemplate>
</asp:TemplateField>
然后，您可以在 CheckedChanged 事件中投射发件人以获取对 CheckBox 的引用，例如：
You can then cast the sender to get reference to the CheckBox at CheckedChanged event like:
protected void CheckBox1_CheckedChanged(object sender, EventArgs e){
CheckBox cb = (CheckBox)sender;
if (cb.Checked){
GridViewRow row = (GridViewRow)cb.NamingContainer;
//access whatever controls here
}
else {
//do something else
}
}
