WHDG Child Bands Give no Data in code behind c#
posted

i have implemented Web Hirachical Data Grid with N Level of childs . on Save Button i need to get the Checked and unchecked Child bands in code Behind but i am getting 0 count on  WebHierarchicalDataGrid1.GridView.Rows[row.Index].RowIslands. 

My Code Behind code is :

protected void WebHierarchicalDataGrid1_RowIslandDataBound(object sender, RowIslandEventArgs e)
{
if (hdgEnterExit.GridView.Rows[0].RowIslands.Count > 0)
{
var childGrid2 = hdgEnterExit.GridView.Rows[0].RowIslands[0];

foreach (GridRecord record in childGrid2.Rows)
{
var c = record.Items[0].FindControl("chkChon") as CheckBox;

if (c != null && c.Checked)
{

}
// userListId += record.Items[1].Value + ";";
}
}

}


protected void btnSaveAccessGrid_Click(object sender, EventArgs e)
{

foreach (GridRecord row in hdgEnterExit.Rows)
{
// var b = row.Items[0].FindControl("chkChon") as CheckBox;

// Get row island using data member
if (hdgEnterExit.GridView.Rows[row.Index].RowIslands != null &&
hdgEnterExit.GridView.Rows[row.Index].RowIslands.Count > 0)
{
var childGrid2 = hdgEnterExit.GridView.Rows[row.Index].RowIslands[0];

foreach (GridRecord record in childGrid2.Rows)
{
var c = record.Items[0].FindControl("Operation") as CheckBox;

if (record.Items[2].Value.Equals("thuynt.bic"))
{
string x = "1";
}
if (c != null && c.Checked)
{

}
//userListId += record.Items[1].Value + ";";
}
}


}


int count = hdgEnterExit.Rows.Count;


for (int i = 0; i < count; i++)
{
var a = hdgEnterExit.Bands.FindByDataMember("TRN_CODE").Columns.FromKey("Menu_Label");
//var Bands = hdgEnterExit.Rows[i].Items.Grid.DataKeyFields().;
// var row = hdgEnterExit.getChildRow

// if (Convert.ToBoolean(hdgEnterExit.Rows[i].Items.FindItemByKey("Menu_Label").Value) == true)
//{

//POST[j] = Convert.ToBoolean(grdPay.Rows[i].Items.FindItemByKey("All_Post_Checkbox").Value) == true ? 1 : 0;
//Status[j] = 1; // processed
//ParticipantCode[j] = Convert.ToString(grdPay.Rows[i].Items.FindItemByKey("PARTICIPANT_CODE").Value);

//System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("en-GB");
////SettlementDate[j] = DateTime.Parse( grdPay.Rows[i].Items.FindItemByKey("SETTLEMENT_DATE").Value.ToString());
////SettlementDate[j] = Convert.ToDateTime()
//SettlementDate[j] = Convert.ToDateTime(grdPay.Rows[i].Items.FindItemByKey("SETTLEMENT_DATE").Value.ToString(), culture);
//ProcessedDate[j] = GetSystemDate();
//IsMannual[j] = 1;
//LogID[j] = Log_ID;
//RefNumber[j] = SystemUtil.GetNextRefNo(CurrentRefernceNumber);
//CurrentRefernceNumber = RefNumber[j];
//j = j + 1;

// }


}
