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

你的问题太不清楚我不完全确定如果我正确地跟着你如果您在检查 CheckBox 时尝试访问列值，则可以执行以下操作：



ASPX：

You question is too unclear and I'm not entirely sure if I follow you correctly. If you are trying to access a Column value when a CheckBox is checked then you can do something like this:

ASPX:

<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
        }
}
