selection out of range parameter name value error.

[Tarang]

Hi ,
My page has the following feature.
when clicked on any grid on page A,it will take few values in form of query string and fetch records on Page B based one the search criteria in the query string.
Problem is I get the error during the dataBind of page load of Page B.

 

Here is my code of PAGE B

  

protected void Page_Load(object sender, EventArgs e)

{

if (IsPostBack) return;

 gvSearchResults.EmptyDataText =  " ";

gvSearchResults.Columns[3].Visible = false;

gvSearchResults.Columns[4].Visible = false;

gvSearchResults.DataSource = null;

gvSearchResults.DataBind();

/** going to assume that the only mode passing in is search */

if (Request["mode"] != null)

{

if (Request[SearchConstants.PARM_BIZDT] != null)

{

string strDt = Request[SearchConstants.PARM_BIZDT];

try 

{

DateTime dt =

DateTime.ParseExact(strDt, SearchConstants.PARM_BIZDT_FORMAT, DateTimeFormatInfo.InvariantInfo);

StartDT.SelectedDate = dt;

EndDT.SelectedDate = dt;

}

catch (Exception ex)

{
log.Error( "Unable to parse search parm session date", ex);

}

}

if (Request[SearchConstants.PARM_EXCHANGETYPE] != null)

ContractSelect.Exchange = Request[

SearchConstants.PARM_EXCHANGETYPE];//.Substring(0, 4); 

else 

ContractSelect.Exchange = "";

//if (Request[SearchConstants.PARM_COMMODITY] != null) 

//{ 
// string strCommodity = Request[SearchConstants.PARM_COMMODITY].ToString(); 

// ContractSelect.Commodity = strCommodity;//.Substring(0, 2); 

 //} 

//else 

// ContractSelect.Commodity = ""; 

if (Request[SearchConstants.PARM_YEAR] != null)

{

try 

{

if (Request[SearchConstants.PARM_YEAR].Length >= 4)

ContractSelect.SetYear = int.Parse(Request[SearchConstants.PARM_CONTRACT_YEAR]);

}

catch (Exception ex)

{ log.Error( "Invalid contract year passed in.", ex);

} }

else 

ContractSelect.SetYear = 0;

if (Request[SearchConstants.PARM_MONTH] != null)

{ try 

{ ContractSelect.SetMonth = 

int.Parse(Request[SearchConstants.PARM_MONTH]);

}

catch (Exception ex)

{log.Error( "Invalid contract month passed in.", ex);

}

}

else 

ContractSelect.SetMonth = 0;

if (Request[SearchConstants.PARM_NUM] != null)

{

string value=Request[SearchConstants.PARM_NUM];

try 

{

hidAccountNum.Value = value;

}

catch (Exception ex)

{cmbAccount.Items.Add(new RadComboBoxItem(value, value));

cmbAccount.SelectedValue = value;

}

}

string str = String.Format("setTimeout(\"{0}.ajaxRequest(\'SEARCH\')\", 250);", RadAjaxManager1.ClientID);

ClientScript.RegisterStartupScript(Page.GetType(),"StartSearch", str, true); }

else 

{

DateTime lastSession = service.GetLastTradeSession();

StartDT.SelectedDate = lastSession;

EndDT.SelectedDate = lastSession;

}

btnExportExcel.OnClientClick = 

string.Format(@"{0}.__doPostBack('{1}', '{2}'); return false;",

RadAjaxManager1.ClientID, btnExportExcel.UniqueID,

btnExportExcel.CommandArgument);

TypeSelect.TradeType = "";

DataBind();   //error is here.  

}

Please let me know if you require anything else to understand the issue.

Thanks,
Tarang

Hello Tarang,

//RadComboBox combo1 = new RadComboBox();
            if (combo1.FindItemByValue("value") != null)
            {
                combo1.FindItemByValue("value").Selected = true;
            }

Thanks,
