说实话

foreach (Control ctl in Repeater1.Controls)
{
if (ctl is CheckBox)
{
(ctl as CheckBox).Checked = true;
}
}

和

foreach (Control c in this.Repeater1.Controls)
{

CheckBox check = (CheckBox)c.FindControl("cbDelete1");
if( check != null )
{
check.Checked = true;
}
}

还真是不行,我按照"jack20080808"给的这个

for (int i = 0; i < rptFriend.Items.Count; i++)
{
if ((rptFriend.Items[i].FindControl("chkId") as CheckBox).Checked)
{

}
}

自己改造里一个,绝对没问题了,

for (int i = 0; i < oneList.Items.Count; i++)
{
Repeater ListTow = (Repeater)oneList.Items[i].FindControl("towList");

foreach (RepeaterItem item in ListTow.Items)
{
CheckBox chkbox1 = (CheckBox)item.FindControl("chkId");
if (chkbox1.Checked == true)
strWhere = strWhere + chkbox1.Text.ToString() + ",";
}
}

        for (int i = 0; i < oneList; i++)
        {
            if ((oneList.Items[i].FindControl("chkId") as CheckBox).Checked)
            { 
            
            }
        }

        {
            if ((rptFriend.Items[i].FindControl("chkId") as CheckBox).Checked)
            { 
            
            }
        }

简化一下,是嵌套的Repeater.

[antiking]

foreach (Control ctl in Repeater1.Controls)
{
if (ctl is CheckBox)
{
(ctl as CheckBox).Checked = true;
}
}

楼上的难道不可以吗

[claymore1114]

foreach (Control c in this.Repeater1.Controls)
{

CheckBox check = (CheckBox)c.FindControl("cbDelete1");
if( check != null )
{
check.Checked = true;
}
}

[搬砖de蚂蚁]

foreach (Control ctl in Repeater1.Controls)
{
if (ctl is CheckBox)
{
(ctl as CheckBox).Checked = true;
}
}
