BachEditing Row to Row Value don't stay if not focused

Hi Kevin, i need your help quickly about a similar problem :

http://www.telerik.com/forums/itemdatabound-even-in-batch-edit-mode-of-rad-grid

The comboBox works with static WebMethod enableLoadOnDemand=true, autopostback=false option under Radgrid BatchEdit in Row Edit mode.
When I add a new row with the Edit mode (EditItemTemplate > RadComboBox), I select a value in second line RadComboxBox and close editMode : the first ItemTemplate takes the value of the second newly input.

The this a real problem

Scenario Step 1 :

Scenario Step 2 :

Scenario Step 3 :

Scenario Step 4 : the first field red line value should be 71886 but automatically change by 147244 ??

Can you give me some alternative or give me an issue for this problem .

RadGrid Data Bind at client side using PageMethod

Dear All

I created a page method that return the result data source in json string format to bind the RadGrid:

[WebMethod]

public static string GetRows(int from, int len)

{

DataTable dt = MyEntity_BL.GetData();

//convert DataTable into Json string

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();

Dictionary<string, object> row = null;

foreach (DataRow dr in dt.Rows)

{

row = new Dictionary<string, object>();

foreach (DataColumn col in dt.Columns)

{

row.Add(col.ColumnName, dr[col]);

}

rows.Add(row);

}

return serializer.Serialize(rows);

}

and then i call the page method at client side at user button click:

function btnShowClientClick(clickedButton) {

PageMethods.GetRows(0, 0, Succsess);

}

function Succsess(result) {

var masterTable = $find("<%= grd.ClientID %>").get_masterTableView();

masterTable.set_dataSource(result);

masterTable.rebind();

}

The problem is that there no action done on the RadGrid ??
It doesn't bind any data!

Is there something miss ?

Thanks

Using onserverclick in PagerTamplate to export Grid to CSV

I am using a RadGrid element and need to export CSV data from it. When I place a link outside of the RadGrid element, the export works fine:

<telerik:RadGrid ID="myGrid" runat="server" EnableViewState="false">

etc...

Now when I place that same link within the PagerTemplate, it no longer works and I get a javascript popup error.

<telerik:RadGrid ID="myGrid" runat="server" EnableViewState="false">

<MasterTableView

And the export method..

protected void Export_CSV_Click(object sender, System.EventArgs e)

{

myGrid.MasterTableView.ExportToCSV();

}

How would I get this button working from within the PagerTemplate?

[Solved] RadGrid Does Not Render Opening Table Tag in Visual Studio 2013

Am having an issue using the RadGrid control in Visual Studio 2013's built in web server. The table element is not be rendered. The same page will render correctly when using Visual Studio 2012's built in web server.

Please advise. Is this an issue with RadGrid or Visual Studio 2013?

Here is snip of the rendered HTML when site run in Visual Studio 2013. Note the lack of an opening table tag.

<div id="grdDemo" class="RadGrid RadGrid_Office2007">

Jones</td><td>Martha</td>

</tr><tr class="rgAltRow" id="grdDemo_ctl00__1">

<td>Noble</td><td>Donna</td>

</tr><tr class="rgRow" id="grdDemo_ctl00__2">

<td>Smith</td><td>Jon</td>

</tr><tr class="rgAltRow" id="grdDemo_ctl00__3">

<td>Tyler</td><td>Rose</td>

</tr>

</tbody>

</table><input id="grdDemo_ClientState" name="grdDemo_ClientState" type="hidden" />

</div>

Here is the aspx markup

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>

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

<body>

<form id="form1" runat="server"><asp:ScriptManager ID="smDefault" runat="server"></asp:ScriptManager>

<div>

<telerik:RadGrid ID="grdDemo" runat="server" AutoGenerateColumns="false">

<ClientSettings>

<Resizing AllowColumnResize="true" ResizeGridOnColumnResize="true" AllowResizeToFit="true" />

</ClientSettings>

<MasterTableView ItemType="Contact">

<Columns>

<telerik:GridTemplateColumn HeaderText="Last Name">

<ItemTemplate><%#: Item.LastName %></ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="First Name">

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

</div>

</form>

</body>

</html>

Here is the C# code behind

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

List<Contact> contacts = new List<Contact>();

contacts.Add(new Contact() { LastName = "Smith", FirstName = "Jon" });

contacts.Add(new Contact() { LastName = "Tyler", FirstName = "Rose" });

contacts.Add(new Contact() { LastName = "Jones", FirstName = "Martha" });

contacts.Add(new Contact() { LastName = "Noble", FirstName = "Donna" });

var data = contacts.OrderBy(c => c.LastName).ThenBy(c => c.FirstName);

this.grdDemo.DataSource = data;

this.grdDemo.DataBind();

}

Here is the Contact class

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

/// <summary>

/// Summary description for Contact

public class Contact

{

public Contact()

{

//

// TODO: Add constructor logic here

}

public string FirstName { get; set; }

public string LastName { get; set; }

Radfilter textbox German numeric format issue

Hi,

I'm filtering my grid column using RadFilter. For numeric columns for en-US (english) culture with value 0.5 it is working fine.

But if I change my culture to german (de-DE), Radfilter textbox is accepting value as 0,5 (which is correct) and my grid column also filtered with 0,5 values, but radfilter textbox converting 0,5 value as 5,00 which is not correct. It should show as 0,5.

<telerik:RadFilter runat="server" ID="rfControllers" FilterContainerID="RadFilter1" ShowApplyButton="true" Visible="true" Skin="Web20"></telerik:RadFilter>

Please refer to the attachment.

Please help me.

Steps no Enabling

I have a RadWizard on a page that contains about 6 steps. Several of the steps either have buttons that open RadWindows or combo boxes. Additionally, several of the pages have their own validation groups and javascript validation functions associated with them. In general the flow of the wizard is fine and everything works like I want, with the exception of the Enabled state of the Navigation steps at the top of the wizard changing. As I proceed through the steps it doesn't enable the past tabs.

How can I fix this behavior?
