Please can someone provide some guidance on why the following is not working.

<telerik:RadNumericTextBox ID="lnVoltage" runat="server" Label="Voltage (V): " Width="160" ToolTip="Three phase voltage" MinValue="0" MaxValue="1000" Value="400" NumberFormat-DecimalDigits="0" DataType="Double" ShowSpinButtons="true" >

<ClientEvents OnValueChanged="singlePhVoltage" OnLoad="singlePhVoltage" />

</telerik:RadNumericTextBox>

<telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">

<script type="text/javascript">

<!--

function singlePhVoltage(sender, eventArgs) {

alert("in function");

}

-->

</script>

</telerik:RadCodeBlock>

When I change the textBox value the function is not being called. Have tried several things.

Problem using HierarchyLoadMode Client

Hello,
I have a hierarchy grid with one nested level.
I'm having some issues with HierarchyLoadMode setting set to Client on my grid.
I load my grid on during Page_Load event, and it is loaded without any issues.
After that, the event to load the DetailTable is called:

protected void RadGrid1_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

{

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

string paramID = dataItem.GetDataKeyValue("Param_Id").ToString();

string sConnectionString = "My Connection String";

SQLDataSource1.SelectParameters["ModelIdParam"].DefaultValue = paramID ;

SQLDataSource1.ConnectionString = sConnectionString;

e.DetailTableView.DataBind();

}

I get an exception - + ex {"Invalid attempt to call FieldCount when reader is closed."}

I am not sure what I'm doing wrong, because if I don't set hierarchyModeLoad to Client, the exact same code runs without any issues, and I can expand/collapse the rows.

I would appreciate any help.

HTTP 502 Errors

Hello,

Recently I have migrated our development evironment over to IIS 7 on Windows 2008 from IIS 6 on Windows 2003. Everything seemed to be working fine at first. However, I noticed when I tested the website on a workstation when logged on as a user without internet access, the site continues to get a 'Telerik' is undefined error message. Using Fiddler, I was able to see the problem is there are calls to the following websites, aspnet-skins.telerikstatic.com or aspnet-scripts.telerikstatic.com. Becuase this user does not have internet access, these calls are failing with HTTP 502 errors and causing issues with all the Telerik controls.

Is there something that needs to be done to avoid these external calls from being made so users without internet access do not have this issue and the site/controls are displayed properly?

Thanks,
Ron

CommandItemTemplate Question - Detail Tables Edit Indexes Count and How to Make a Detail Table Row Selected /Last Inserted Updated Row at All Times

Folks,

Using VS2010 with RadControls for Ajax Q1 2012.

I need some help with following issues:

1) For Example, while using Command Item Template, I can hide the the EditSelected Command Button based on RadGrid1.EditIndexes.Count of Master Table, How can I accomplish the same result with Child Table (i.e. hide EditSelected Command Button based on RadGrid1.EditIndexes.Count of Child Table)? Basically I do not want to show Child Table EditSelected Command if there are no Child rows.

To get Child Table Edit Indexes count I tried to below line of code but is not working.

Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>

Below is my Master/Detail Command Items Template.

<Mastertableview width="100%" commanditemdisplay="Top" datasourceid="SqlDataSource1" name = "Master"

datakeynames="CustomerID">

<CommandItemTemplate>

<div style="padding: 5px 5px;">

Custom command item template for Master table

<asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected"

Visible='<%# RadGrid1.EditIndexes.Count == 0 %>'><img style="border:0px;vertical-align:middle;"

alt="" src="Images/Edit.gif" />Edit selected Master Row</asp:LinkButton>

<asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited"

Visible='<%# RadGrid1.EditIndexes.Count > 0 %>'><img style="border:0px;vertical-align:middle;"

alt="" src="Images/Update.gif" />Update Selected Master Row</asp:LinkButton>

'''

</div>

</CommandItemTemplate>

<DetailTables>

<telerik:GridTableView DataKeyNames="OrderID,ProductID" DataSourceID="SqlDataSource3"

Width="100%" runat="server" CommandItemDisplay="Top" Name="Details">

<CommandItemTemplate>

<div style="padding: 5px 5px;">

Custom command item template for Child Table

<asp:LinkButton ID="btnEditSelectedChildRow" runat="server" CommandName="EditSelected"

Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>

<img style="border:0px;vertical-align:middle;"

alt="" src="Images/Edit.gif" />Edit selected Child Row</asp:LinkButton>

<asp:LinkButton ID="btnUpdateSelectedChildRow" runat="server" CommandName="UpdateEdited"

Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>

<img style="border:0px;vertical-align:middle;"

alt="" src="Images/Update.gif" />Update Selected Child Row</asp:LinkButton>

'''

</CommandItemTemplate>

</telerik:GridTableView>

</DetailTables>

</Mastertableview>

2) Below link from Telerik Documentation shows Making a Grid Row Selected at All Times (similar to WinForms grids). How can I accomplish the same result with Child Table (I have multiple Child Tables)?

http://www.telerik.com/help/aspnet-ajax/grid-selected-row-at-all-times.html

3) Below Thread solution by Princy demonstrated Select Inserted/Updated row after performing command in Master Table. How can I accomplish the same result with Child Table (I have multiple Child Tables)?

http://www.telerik.com/community/forums/aspnet-ajax/grid/select-inserted-updated-row-after-performing-command.aspx

Thank you very much for any help.

Sincerely
