Call javascript when Row is Updated and Grid is Refreshed

I feel I'm doing this the hard way, and I'm hoping you can set me straight. I have a grid with EditMode="PopUp" and EditFormType="Template". In this grid's FormTemplate, I have the following save image to click...

<asp:ImageButton ID="imgSave" runat="server" TabIndex="120" AlternateText="Save"

ImageUrl="~/images/icons/save-24.jpg" ToolTip="Save"

CommandName='<%# IIf (TypeOf Container is GridEditFormInsertItem, "PerformInsert", "Update") %>' />

Before it saves, I validate certain data. So in the grid's ItemDataBound event, I assign to the imgSave's "onclick" attribute a javascript function with various control ClientIDs in the popup. If certain conditions fail, javascript gives an alert and does "return false" to keep the popup from closing. If the data is good, I "return true" to let the popup close and refresh the grid's data. It works well.

Now this is where I've goofed up. What I want, is after the grid is rebound/refreshed, I want to highlight the edited row and display certain stats beneath the grid. I've written the code, but don't know how to call it. Is there an event I can tie to my javascript function? (I tried OnActiveRowChanged, but it didn't fire.)

To get around this, just before my "return true" that closes the popup form, I added these two lines of code...

var f = function() { UpdateStatusBar(iKey); };

setTimeout(f, 1000);

return true;

Having the 1 second delay gives the grid time to rebind/refresh before calling my UpdateStatusBar function, but that's open to timing issues. What should I do instead?

Single radiobutton check at a time

I found this article http://www.telerik.com/community/code-library/aspnet-ajax/grid/single-radiobutton-check-at-a-time-with-row-selection.aspx
and it helped me for a while. I made it working partially. The problem is that it does work only on a single page. If paging is applied on the listview and the selected radiobutton (on LOAD) is on the page #2 or higher it will be not unchecked.

How to make it works across all the pages in the ListView? Means if i select radiobutton on a page #5 and then go to page #2 and check new radiobutton the one from page #5 should be unchecked.

Thanks

Binding hierarchical grid with complex object

I have what I hope is a simple question, but I can't seem to find an example. I have the following object structure (for example):

public class Invoice

{

public int InvoiceId { get; set; }

public string CustomerName { get; set; }

public double Total { get; set; }

public List<InvoiceLineItem> LineItems { get; set;}

}

public class InvoiceLineItem

{

public string Description { get; set; }

public int Quantity { get; set; }

public decimal Rate { get; set; }

public decimal Total { get { return Quantity * Rate; } }

}

I want to bind a list of Invoice to this hierarchical grid using HierarchyLoadMode="Client" , preferably declaratively, and without hooking DetailTableDataBind (I have already solved it this way, but it seems there should be a much better way). Is there a way to express the relationship? All the data is preloaded and ready to be bound.

Current Solution:

protected void RadGridInvoices_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)

{

var invoices= e.DetailTableView.DataSource as IEnumerable<Invoice>;

if (invoices != null)

{

string invoiceId =

e.DetailTableView.ParentItem.GetDataKeyValue("InvoiceId").ToString();

var invoice = invoices.First(inv => inv.InvoiceId == invoiceId);

e.DetailTableView.DataSource = invoice.LineItems;

}

Thanks,
Mark Huber

rcbArrowCell FireFox and Safari Issue

VS 2008
Telerik 2010.2.713.35

.rcbArrowCell {background-image: none !important;} works great in IE, but in FF and Safari, the image only partly disappears (a thin vertical line remains). How can I make it invisible in FF and Safari?

Example below:

Page:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</style>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title>Untitled Page</title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="Scriptmanager1" runat="server">

</asp:ScriptManager>

<div>

<asp:Table ID="Table1" runat="server">

<asp:TableRow ID="TableRow1" runat="server">

</telerik:RadComboBox>

</asp:TableCell>

</asp:TableRow>

</asp:Table>

</div>

</form>

</body>

</html>

Code:

Imports Telerik.Web.UI

Partial Class _Default

Inherits System.Web.UI.Page

Private Sub DisableArrow(ByVal cbo As RadComboBox)

Dim cboID As String = "#" + cbo.ClientID

Dim ltrl As New LiteralControl()

ltrl.ID = "HideArrowCSS"

ltrl.Text = cboID + " .rcbArrowCell {background-image: none !important; border: 0; padding: 0; width: 0px; background-color: Transparent;} "

ThemeCSS.Controls.Add(ltrl)

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

RadComboBox1.Height = 0

RadComboBox1.Width = 0

DisableArrow(RadComboBox1)

End Sub

End Class

RadGrid Programmatic Load-On-Demand Troubles

Hello,

I really need to be able to programmatically create, and populate a hierarchical radgrid.

right now I am just working on two levels (master, one detail) and am trying to setup the load-on-demand functionality. I am getting the master to load, but when i try and expand a row, it just sits forever (with the statusbar doing something).

The query it is running for a row shouldn't take much longer than a second... here is the code I am working with:

protected void Page_Load(object sender, EventArgs e)

{

_Grid.DetailTableDataBind += new GridDetailTableDataBindEventHandler(_Grid_DetailTableDataBind);

_Grid.NeedDataSource +=new GridNeedDataSourceEventHandler(_Grid_NeedDataSource);

LoadGrid();

}

void _Grid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

if (!e.IsFromDetailTable)

{

_Grid.DataSource = GetDataTable("county:zavala");

}

void _Grid_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

switch (e.DetailTableView.Name)

{

case "PARENT":

{

//string ID = dataItem.GetDataKeyValue("ID").ToString();

e.DetailTableView.DataSource = GetDataTable("county:zavala");

break;

}

case "CHILD":

{

string cscpID = dataItem.GetDataKeyValue("cscpID").ToString();

e.DetailTableView.DataSource = GetDataTable("cscpID:" + cscpID + " view:WP");

break;

}

private SqlCommand QueryCommand(string Query)

{

SqlConnection conn = new SqlConnection(GetConnectionString("connTGS_"));

SqlCommand cmd = new SqlCommand("tgs_.pd.NewQuery", conn);

cmd.CommandType = CommandType.StoredProcedure;

SqlParameter qry = cmd.Parameters.Add("@Query", SqlDbType.NVarChar, 2000);

qry.Value = Query;

SqlParameter iserror = cmd.Parameters.Add("@iserror", SqlDbType.Bit, 1);

iserror.Value = false;

return cmd;

}

private DataTable GetDataTable(string query)

{

SqlCommand cmd = QueryCommand(query);

SqlDataAdapter dA = new SqlDataAdapter(cmd);

DataTable dT = new DataTable();

dA.Fill(dT);

return dT;

}

private void LoadGrid()

{

if (!Page.IsPostBack)

{

_Grid.PageSize = 20;

_Grid.AllowPaging = true;

_Grid.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;

_Grid.AutoGenerateColumns = false;

_Grid.ShowStatusBar = true;

_Grid.ClientSettings.AllowColumnsReorder = true;

_Grid.ClientSettings.AllowDragToGroup = true;

_Grid.ClientSettings.AllowColumnHide = true;

InitRootBand(ref _Grid);

InitChildBand(ref _Grid);

}

_radAjaxMan.AjaxSettings.AddAjaxSetting(_Grid, _Grid);

}

private void InitRootBand(ref RadGrid grid)

{

//grid.DataMember = "PARENT";

grid.MasterTableView.DataKeyNames = new string[] { "id" };

grid.Columns.Add(newColumn("id", "ID", "id", null, false));

grid.Columns.Add(newColumn("cid", "cID", "p_cID", null, false));

grid.Columns.Add(newColumn("opid", "opID", "p_opID", null, false));

grid.Columns.Add(newColumn("CompanyName", "Company Name", "p_CompanyName", null, false));

}

private void InitChildBand(ref RadGrid grid)

{

GridTableView tableWP = new GridTableView(grid);

grid.MasterTableView.DetailTables.Add(tableWP);

//tableWP.DataMember = "CHILD";

tableWP.Name = "CHILD";

tableWP.DataKeyNames = new string[] { "cscpID" };

tableWP.Columns.Add(newColumn("ID", "ID", "ID", null, false));

tableWP.Columns.Add(newColumn("cscpID", "cscpID", "cscpID", null, false));

tableWP.Columns.Add(newColumn("cid", "cID", "c_cID", null, false));

tableWP.Columns.Add(newColumn("FirstMonth", "First Month", "c_FirstMonth", "{0:MMM-yy}", false));

GridRelationFields drMain = new GridRelationFields();

drMain.MasterKeyField = "id";

drMain.DetailKeyField = "cscpID";

tableWP.ParentTableRelation.Add(drMain);

}

private GridBoundColumn newColumn(string fieldName, string headerText, string Key, string format, bool hidden)

{

GridBoundColumn fld = new GridBoundColumn();

fld.DataField = fieldName;

fld.DataFormatString = format;

fld.HeaderText = headerText;

fld.Display = !hidden;

return fld;

}

Please, any help is appreciated! Getting past this road block is crucial!

Checkbox in template column of radgrid

Hello Team,

I have searched over the forum to get a solution but I am finding my issue is quite different than what I have found so far.

I have grid of users that will be selected with a clientselectcolumn and I have a separate template column of checkboxs that I want to set only one of the selected users as the main user or admin user. I need help to achieve the following:

1. Client side validation to allow only one checkbox to be selected at a time for the admin user when a checkbox is selected.

2. Persist the checked state of checked box upon paging or sorting.

Could you please point me in to some sources or provide me with pointers.

Thank you.
