selection out of range parameter name value error.

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

Hi ,

I Recently upgraded my Telerik's DLLs from version 2010.3.1215.40 to 2012.1.215.40 version.
On successful upgrade of the Dll's I found below Properties are missing at the Asp.net Ajax RadGrid 2012.1.215.40 's 'GridSelecting'
class.

AllowCellSelect
AllowColumnSelect
AllowMultiCellSelect
AllowMultiColumnSelect

I would like to know whether these properties are removed intentionally or these provided some where else in the Latest Dll's.

InlineInsertTemplate without recreating all the slots

Hi,

In scheduler I'm loading big amount of events information via sqldatasource. And I need only for the user to choose a free slot and hit the button "book it" then he will be redirected to other page.I'm using custom InlineInsertTemplate. The problem is - that when clicking any free slot, all scheduler data gets repopulated it takes about 2-3 seconds to complete. Is it possible to load the data once and and void only InlineInsertTemplate without recreating all the slots? Thanks in advance

adding external stylesheet

Hi,

I have a radgrid whose css is defined in an external stylesheet. I am mainly looking for the height of the radgrid and the width of each of the columns.
The radgrid remains unaffected inspite of the css. I am adding the external style sheet on the server-side in the Page Load like this:

HtmlLink link = new HtmlLink();

link.Attributes["href"] = "~/Styles/Grids.css";

link.Attributes.Add("type", "text/css");

link.Attributes.Add("rel", "stylesheet");

Page.Header.Controls.Add(link);

What am I doing wrong?

Javascript error when click print function in a RadAjaxPanel

Hi:
I just placed my working chart inside a RadAjaxPanel and the print functionally is giving me a javascript runtime error on the { before the finally.

try{a._webRequest.completed(Sys.EventArgs.Empty)}finally{if(a._xmlHttpRequest!=null)

The JScript message says, it may be caused by response.write.

Using _ms As System.IO.MemoryStream = New System.IO.MemoryStream()

_radChart.Save(_ms, System.Drawing.Imaging.ImageFormat.Png)

page.Response.Clear()

page.Response.ClearHeaders()

page.Response.AddHeader("Content-disposition", "attachment; filename=" & pngName & ".png")

page.Response.AddHeader("Content-type", "image/png")

page.Response.BinaryWrite(_ms.ToArray())

page.Response.End()

End Using

So, there is the response write. So, how am I supposed to get the PNG image to the users?

{

var childNode = node.get_nodes().getNode(i);

DetermineMode(childNode, isChecked, false);

CheckNodeChildren(childNode, isChecked);

}

return true;

}

else return false;

}

function DetermineMode(node, isAllNodeChecked, isSomeNodeChecked)

{

if (isAllNodeChecked)

{

SetMode_TotalAccess(node);

}

else if (isSomeNodeChecked)

{

SetMode_PartialAccess(node);

}

else

{

SetMode_ForbiddenAccess(node);

}

function SetMode_TotalAccess(node)

{

node.set_checked(true);

node.set_imageUrl("/image/checked.gif");

node.set_text("Total");

// node.set_toolTip(\ TOOLTIP_PictureTotal \);

}

function SetMode_ForbiddenAccess(node)

node.set_checked(false);

node.set_imageUrl("/image/deleted.gif");

node.set_text("Forbidden");

Formatting for Blogs

Is there a way to set up the Text Editor to be able to format the position of uploaded pictures and videos with respect to the text that is typed in? Mainly I'm talking about text wrapping and the margins that are placed around those pictures and videos. This is something that is needed if the text editor is used in conjuntion with a blog. Is there already a setting in place to adjust this or where would I have to specify this in the code?

Thanks
