{
DataTable dt = null;
CheckBox chk;
foreach(GridViewRow gvrow in gvPR.Rows)
{
//chk = (CheckBox)(gvPR.Rows[i].Cells[0].FindControl("chkFru"));
chk = (CheckBox)gvrow.FindControl("chkFru");
if (chk.Checked == true)
{
dt = objCert.BuildCertInfo();
DataRow dr = dt.NewRow();
// HtmlInputHidden hdn = (HtmlInputHidden)(gvPR.Rows[i].Cells[0].FindControl("hdnFruId"));
HtmlInputHidden hdn = (HtmlInputHidden)gvrow.FindControl("hdnFruId");
string strFru = hdn.Value;
dr[Certificate.SYS_SERIAL_NUMBER] = strFru;
//get Fru info
dsInfo = objCert.GetFruInfo(strFru);
if (dsInfo == null)
{
setError(lblCertErr, Certificate.NO_SYS_INFO);
return;
}
dr[Certificate.SYS_PART_ID] = dsInfo.Tables[0].Rows[0]["part_id"].ToString();
dr[Certificate.SYS_PART_DESC] = dsInfo.Tables[0].Rows[0]["Part_desc"].ToString();
dr[Certificate.SYS_SERIAL_NUMBER] = dsInfo.Tables[0].Rows[0]["Serial_Number"].ToString();
dr[Certificate.LOC] = dsInfo.Tables[0].Rows[0]["Location"].ToString();
dt.Rows.Add(dr);
}
}
LoadWizStep2(dt);
}
and the method for LoadWizStep2(dt) 和LoadWizStep2(dt)的方法
private void LoadWizStep2(DataTable dt)
{
try
{
wizController.ActiveStepIndex = 1;
GridView2.DataSource = dt;
GridView2.DataBind();
Session["FRU_INFO"] = dt;
}
catch (Exception ex)
{
throw ex;
}
}
and this is code for aspx page 这是aspx页面的代码
<table width="100%" cellpadding="0" cellspacing="0" style="background-color: White">
<tr style="width: 100%">
<td colspan="2" align="left">
<asp:GridView ID="gvPR" runat="server" AutoGenerateColumns="False" GridLines="None"

would any one please suggest ideas on this 任何人都可以对此提出建议吗
add a count and increment it inside 添加一个计数并在内部递增
int count=0
If(chk.checked)
{
count++
}
and
if(count>0)
{
//load step 2
}
You Will fine here more easy code 您可以在这里更简单的代码
int count=0;
//ImageButton lbtn = (ImageButton)sender;
DoctorDAO objDoctorDAO = new DoctorDAO();
foreach (GridViewRow row in grd_Data.Rows)
{
CheckBox chk = (CheckBox)grd_Data.Rows[row.RowIndex].FindControl("Chklist");
if (chk.Checked == true)
{
count++;
}
}
if (count > 0)
{
foreach (GridViewRow row in grd_Data.Rows)
{
CheckBox chk = (CheckBox)grd_Data.Rows[row.RowIndex].FindControl("Chklist");
if (chk.Checked == true)
{
ImageButton lbtn = (ImageButton)grd_Data.Rows[row.RowIndex].FindControl("btn_Delete");
objDoctorDAO.deleteDoctor(Convert.ToInt32(lbtn.CommandArgument));
lbl_Msg.Text = " Doctor Deleted Successfully!!";
}
}
}
else
{
lbl_msg3.Text = "Please Check at least one record to Delete";
return;
}
