Hi, I'm using the RadToolBar in the CommandItemTemplate of the RadGrid.
I've adjusted the width of the grid to 100%.
I need to display to the user 12+ independent RadToolBarButton and in some of them I have big text to explain to the user what the action is. The result is that the last buttons are not totally or partially visible. Is there any property in the toolbar or an adjustment possible to be made? maybe a scroll or a '...' or ' >>>' button to view the mentioned buttons?
Thanks, Ariel.

TreeList for Non Self referencing data

Hi people,
in the demo of TreeList it is written that "Its hybrid structure empowers you with the ability to visualize self-referencing data in a hierarchical view defining primary/foreign key relations and using identical objects for source."
I want to know if this control support non-self referencing data? Like

Code Chapter Subchapter
----------------------------------------------------------
123456 12 1234
456789 45 4567
345678 34 3456
124389 12 1243

Here Chapter is the parent of subchapter.

12
-1234
-1243
45
- 4567
34
- 3456

Tell me can this control work for me?

SharePoint Online / ASP.Net & Telerik?

Hi,

I have successfully deployed a test Silverlight application to SharePoint Online, which includes my trial Telerik controls. Specifically ChartView.

We do not however wish to develop future apps in Silverlight, for cross-browser/device compatibility reasons.

Am I able to use the ASP.Net versions of the same controls to develop ASP.Net applications or Webparts in SharePoint Online?

Note: SharePoint Online, not On-Premises.

Thanks,

Jason.

reference to parent grid

Hi,
I have a grid in an editform of another grid. The datasource of the second grid is dependant on a datakeyvalue of the first grid. How do i do this in the NeedDataSource event of the second grid?
If I try and use the SelectedIndex I get nothing as first gris is in edit mode.
I am looking for something like below but unfortunately the row is not selected, just inedit mode:

Protected Sub UserNeedDatasource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs)

Dim DataKey As String = Me.Grid1.MasterTableView.DataKeyValues(Me.Grid1SelectedIndexes(0))("DataKeyName").ToString

Me.Grid2.DataSource = MyDataSource.GetData(DataKey)

end Sub

Any ideas?

Reloading RadGrid Initial Data from DataSource

I want to know a way I can reload the RadGrid with the DataSource that it is originally loading from. Case Scenario would involve the user click on a button to refresh the RadGrid to return the original data from the database, because they don't want the updated changes on the RadGrid anymore. I've tried DataBind, but it does not do anything for me. Is there an event that I need to use to do what I need it to do?
I am using .ASPX and C#. Thanks in advanced.

protected void RadGrid1_Load(object source, GridNeedDataSourceEventArgs e)

{

String ConnString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;

SqlConnection conn = new SqlConnection(ConnString);

SqlDataAdapter adapter = new SqlDataAdapter();

adapter.SelectCommand = new SqlCommand(@"SELECT columns FROM tables)", conn);

DataSet myDataTable = new DataSet();

conn.Open();

try

{

adapter.Fill(myDataTable, "tables");

}

finally

{

conn.Close();

}

DataView myDataView = myDataTable.Tables["tabels"].DefaultView;

RadGrid1.MasterTableView.DataSource = myDataView;

RadGrid1.MasterTableView.DataBind();

}

inconsistent rendering

Hi, I have a very annoying problem with my comboboxes that occurs not everytime but i would say ~5% of the time, testing on IE8 and FF 14.0.1. My scenario (using Q2 2012):

Im having 2 related comboboxes in a RadAjaxPanel which are filled once from a database. Each combobox filters each other since the first one contains the parents of the second. Im using server-side coding to do the filtering (by using item visibility, based on Parent (Attribute) property).

95%, everthing works like it should but i noticed that sometimes the filtering does not occur (selecting an element in the first combobox doesnt filter the second one at all...it visible items stays like there were). I though first that the postback was not occuring on those times but after investigation, it is (OnSelectedIndexChanged gets called and item visibility is set correctly for all items). It's just the displaying that dont get refreshed somehow. The only way I can do something is selecting something else in the first combobox and reselecting the one i really wanted (to force an index change)...then it filters.

I initially had AutoPostBack=True on both comboboxes and tried to put them to false and handle it on client-side (OnClientSelectedIndexChanged), like someone did on a forums. Problem still occuring ...but seems like less often so i kept it like that.

Here's a trimmed down version of my code:

aspx

<telerik:RadAjaxPanel ID="RadAjaxPanel2" runat="server">

<div class="EnterpriseNodes1">

<telerik:RadComboBox ID="RadComboBox1" runat="server" Skin="WebBlue" MarkFirstMatch="true" Visible="false" AllowCustomText="true" Filter="StartsWith" CssClass="combo1" NoWrap="True" OnItemDataBound="RadComboBox1_ItemDataBound" AutoPostBack="false" OnSelectedIndexChanged="RadComboBox1_OnSelectedIndexChanged" OnClientSelectedIndexChanged="RadComboBox1_OnClientSelectedIndexChanged">

</telerik:RadComboBox>

<br />

<telerik:RadComboBox ID="RadComboBox2" runat="server" Skin="WebBlue" MarkFirstMatch="true" Visible="false" AllowCustomText="true" Filter="StartsWith" CssClass="combo2" NoWrap="True" OnItemDataBound="RadComboBox2_ItemDataBound" AutoPostBack="false" OnSelectedIndexChanged="RadComboBox2_OnSelectedIndexChanged" OnClientSelectedIndexChanged="RadComboBox2_OnClientSelectedIndexChanged">

</telerik:RadComboBox>

<br />

</div>

</telerik:RadAjaxPanel>

js

function RadComboBox1_OnClientSelectedIndexChanged(sender, args) {

__doPostBack('RadComboBox1', '');

}

function RadComboBox2_OnClientSelectedIndexChanged(sender, args) {

__doPostBack('RadComboBox2', '');

}

cs

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

RadComboBoxItem item = null;
