RadTextBox visibility issue

I am using the ASP.net version of the rad controls (RadControls for ASP.NET AJAX Q1 2011 SP1). I have a RadComboBox that, when the value is set to Other, should display a RadTextBox for data entry, here is the definition and JavaScript i am using:

<telerik:RadComboBox runat="server" ID="rcbIndustry" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" Skin="Black" Width="269" EnableEmbeddedSkins="false" />

<span id="tmp"></span>

<telerik:RadTextBox runat="server" ID="rtbIndustryOther" Skin="Black" Width="250" EnableEmbeddedSkins="false" />

<script>

function OnClientSelectedIndexChanged(sender, eventArgs) {

if (eventArgs.get_item().get_value() == 'Other') {

$find("#<%= rtbIndustryOther.ClientID %>").set_visible(true);

$("#tmp").html('<br>');

}

else {

$("#<%= rtbIndustryOther.ClientID %>").set_visible(false);

$("#tmp").html('');

}

$find("#<%= rtbIndustryOther.ClientID %>").set_visible(false);

</script>

The last line in the script ($find("#<%= rtbIndustryOther.ClientID %>").set_visible(false);) immediately throws an error:
"Microsoft JScript runtime error: Unable to get value of the property 'set_visible': object is null or undefined"

What am I doing wrong as this is driving me nuts...

Noddy is in da house

Yes, it's time for another dumb questions from yours truly.

I'm often surprised by how many times I find myself doing something for the first time, even though I've been doing this kind of work for a while now. Anyhow, here's the thing. I have a page with code on it that includes this ...

<telerik:RadScriptBlock runat="server" ID="RadScriptBlock1" >

<script type="text/javascript">

$(document).ready(function ()

{

var addEditEventDialog = new CalendarAddEditEventObject();

});

</script>

</telerik:RadScriptBlock>

The constructor of the object being created includes code to attach a couple of client-side event handlers and it all works fine. Until, that is, my page does an Ajax callback. At this point my handlers stop working.

Now, I've found a workaround but I'm unsure if it is the right work around. I've added RadScriptBlock1 in to the set of updated controls in the AjaxManager.

What should I be doing?

Pop up on Drag and Drop

I've run out of ideas on how to do this so I'm hoping one of you will give me an idea.

What I'm trying to do, at the request of our user community, is have a popup open when a user drags/drop a row so they can enter some information.

I'm using jQuery and some jQuery plug-ins in trying to accomplish this, everything works independently but when I try to incorporate it with the drap event it doesn't work.

I've tried squirting the javascript at the end of the rowdrop event of the grid and it does trigger my javascript and I've traced it and it should popup my window but it doesn't, I suspect that the javascript is being triggered at the wrong time in the sequence of events.

Any help would be appreciated.

All I need is a popup with a text area and a OK/Cancel that is triggered at the end of the dropping of a row.

Thanks

Pass parameter to webservice on node expand

Hi,
I am using the webservice method of populating my radtreeview as it was described as the most efficient way to load large amounts of data. So the signature of my webservice method is:

[WebMethod]
public RadTreeNodeData[] WebServiceMethodName(RadTreeNodeData node, object context)

However, the nodes that I am populating the tree with depend on the security access of the user that is logged in to my application..
Is it possible to pass additional parameters to the webservice method? Or must I use a ServerSideCallBack method to populate the tree? I am hoping that I can still use the webservices functionality... I would like to pass a signature like this to my webservice method:
[WebMethod]
public RadTreeNodeData[] WebServiceMethodName(RadTreeNodeData node, object context, object userSession)



I look forward to your response. Thank you!

Charts Programmatically

I have a used one of your chart demonstrations and require a little help.

DataTable table = PageAccess.CountOfEnquiriesBetweenDates(startDate, endDate);

var c = table.Rows.Count;

RadChart radChart = new RadChart();

radChart.ChartTitle.TextBlock.Text = "Enquiries";

radChart.Skin = "DeepGray";

var chartSeries = new ChartSeries {Name = "Enquiries", Type = ChartSeriesType.Bar};

//It works when I just put in a value

chartSeries.AddItem(c, "Enquiries");

from the code above I have executes a stored procedure retruned as a DataTable and I am then counting the number of rows in the table. I need this value to be in the graph data. I have tried Convert.ToDouble(c), I am using VS 2010. Can someone shed any light on what I have done wrong?

Many thanks

Simon

GridDropDownColumn & Binding to Non-foreign Key Columns

Hello,

Imagine two tables, each with two columns.

Operations

UserId

StartedBy

Users

Id

UserName

Operations.UserId is a FK to Users.Id. All columns are integers.

This works:

<telerik:GridDropDownColumn

DataField="UserId"

DataSourceID="UsersDataSource"

HeaderText="UserId"

ListTextField="UserName"

ListValueField="Id"

UniqueName="UserId">

</telerik:GridDropDownColumn>

This doesn't:

<telerik:GridDropDownColumn

DataField="StartedBy"

DataSourceID="UsersDataSource"

HeaderText="Started By"

ListTextField="UserName"

ListValueField="Id"

UniqueName="StartedBy">

</telerik:GridDropDownColumn>

Here's the DataSource:

<asp:EntityDataSource

ID="UsersDataSource"

runat="server"

ConnectionString="name=MyEntities"

DefaultContainerName="MyEntities"

EnableFlattening="False"

EntitySetName="Users"

EntityTypeFilter="User"

OrderBy="it.[UserName]">

</asp:EntityDataSource>

I know the UserId works because it is a foreign key but the second "StartedBy" is just a normal Int32 column in the Db that I have no control over (i.e. no relationship is or will be defined).

Normally, I'd just shrug and roll some code-behind but I'd much rather solve this in the declarative manner.

What is the simplest way I can get my StartedBy dropdown to bind via the value recorded in Operations.StartedBy?

AjaxManagerProxy and Content Areas

The latest controls build seems to break the old solution to the 100% height update panel issue (that of finding the update panel id server-side and setting its height explicitly cliient-side). This breakage is no big deal since I'd like to switch to using the relatively new UpdatePanelHeight property instead of the old hack. However, I have run into an issue. I have a MasterPAge and Contentpage and the latter has two Content Areas. Various controls in each Content are need to ajaxify eachother.

1) I'd like to place an AjaxManagerProxy declaration on the ContentPage so I can make use of the UpdatePanelHeight property, however, I'm not sure how to reference controls in the two contentAreas in the AjaxSettings.

2) OR, I can also set the ajaxSettings server-side, but then I don't know how to set the UpdatePanelHeight property.

Can someone let me know how to do either of these.. though #1 is preferrable.

P.S., it would be nice if you could extend the AddAjaxSetting Method to include a parameter for the UpdatePanelHeight.

Simple chart example

Hi,

Can anyone please help me with an example to bind a chart in the runtime using code behind?
I have stored procedures and .Net class files, with Datatable as output, ready with me.

I need a simple example to bind the chart with these classes' objects in the c# file.

Thanks...
