for循环遍历GV

Answer 2

for (int i = 0; i < this.GridView1.Rows.Count; i++)
            {
                CheckBox cb = this.GridView1.Rows[i].Cells[1].FindControl("CheckBox1") as CheckBox;
                //设定checkbox的选中状态

protected void CheckAll_CheckedChanged(object sender,EventArgs e)
        {
            CheckBox ck = sender as CheckBox;
           
            if (ck != null)
            {
                System.Web.UI.WebControls.GridView g = ck.NamingContainer.NamingContainer as System.Web.UI.WebControls.GridView;
                for (Int32 i = 0; i < g.Rows.Count; i++)
                {
                    (g.Rows[i].FindControl("CheckBox1") as CheckBox).Checked = ck.Checked;
                }
            }
        }
        protected void CheckBox1_CheckedChanged(object sender,EventArgs e)
        {
            var count = 0;
            CheckBox ck = sender as CheckBox;
            if (ck != null)
            {
                System.Web.UI.WebControls.GridView g = ck.NamingContainer.NamingContainer as System.Web.UI.WebControls.GridView;
                for (Int32 i = 0; i < g.Rows.Count; i++)
                {
                    if ((g.Rows[i].FindControl("CheckBox1") as CheckBox).Checked)
                    {
                        count++;
                    }
                }
                (g.HeaderRow.FindControl("CheckAll") as CheckBox).Checked =count==g.Rows.Count;
            }
        }参考

autopostback==true

Answer 5

for (int i=0;i<this.Repeater1.Items.Count;i++) 
{ 
HtmlInputCheckBox check = (HtmlInputCheckBox)this.Repeater1.Items[i].FindControl("cbDelete1"); }或者
foreach( RepeaterItem item in this.Repeater1.Items ) 
{ 
HtmlInputCheckBox check = (HtmlInputCheckBox)item.FindControl("cbDelete1"); }

Answer 6

 foreach (Control c in this.rptTables.Controls)
    {
        CheckBox cbx = (CheckBox)c.FindControl("cbxId");
        if (cbx != null)
        {
            cbx.Checked = true;
        }
    }

Answer 7

#2,#3,#8的就可以搞定.repeater和gridview差不多的

Answer 8

为什么不用JS？，如果用的话,page还不用Postback呢。

Answer 9

 for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            ck1 = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1")
            ck1.Checked=true；

Answer 10

我用的：
protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
    {//复选///////你用Repeater1代替GridView1就可以了
        if (CheckBox2.Checked == true)
        {
            CheckBox2.Text = "全选";
            for (int i = 0; i < GridView1.Rows.Count; i++)
            {
                CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");                cbox.Checked = true;
            }
        }
        else
        {
            CheckBox2.Text = "全不选";
            for (int i = 0; i < GridView1.Rows.Count; i++)
            {
                CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");                cbox.Checked = false;
            }
        }
    }

Answer 11

不管你外围用什么控件来包，最终还不是操作checkbox
