Using SQLDataAdapter to populate Treeview

I have a SQLDataAdapter with a data relation defined thusly:
        Dim cnn As SqlConnection = New SqlConnection(Application("ConnStr"))
        Dim cmd1 As SqlDataAdapter = New SqlDataAdapter("select * from topic_Areas Order by Topic_Name ASC", cnn)
        Dim ds As DataSet = New DataSet()
        cmd1.Fill(ds, "topic_Areas")
        Dim cmd2 As SqlDataAdapter = New SqlDataAdapter("select * from vw_DCMP_Topics_Subjects Order by Subject_Name ASC", cnn)
        cmd2.Fill(ds, "vw_DCMP_Topics_Subjects")
        ds.Relations.Add("myrelation", ds.Tables("topic_Areas").Columns("Topic_Num"), ds.Tables("vw_DCMP_Topics_Subjects").Columns("Topic_Num"))
       'some form of setting the Treeview datasource on this line
        Page.DataBind()
        cnn.Close()

I would like to have the Parent nodes populated with the topic_areas and the child nodes for each parent node filled with the vw_DCMP_Topics_Subjects related data.

Is if possible to do this with the Treeview and if so how would one do this?

Thanks in advance.

Proxied application - need to use full client-side library?

Hello,

I am developing a web application that is accessed two ways: through a LAN and through a gateway. It works fine when accessed over the LAN, but breaks when accessed over the gateway because of the AJAX in the application. Of course the AJAX is there because there is substantial use of Telerik controls :)

The problem is that there is a directory structure in the gateway URL. When it tries to load the objects, it looks for /ScriptResource.axd?d=blob&t=timestamp and cannot find it, so none of the Telerik AJAX controls work properly.

Anyway, I've read that you can force the ScriptManager to use static files. I've set it to use a static Telerik.Web.UI file (as shown in the static client side library), but I see that isn't the only Telerik script that is loaded. On one particular page (on which there are about 10 Telerik controls) I see there are numerous other calls to ScriptResource.axd that generate client side code to handle the Telerik controls. Is there any way I can reference those in the <scripts> section of the <scriptmanager>, and perhaps save them as static files as well?

Or is there another solution to this gateway problem?

Thanks!!

Use tool bar button to insert tags at beginning and end of selected text

On a custom toolbar button click I would like to insert a start html tag at begining of selected content and and an close tag at the end of the selection.

There is a help on inserting HTML tag at the beginning of the selection, the problem is inserted the close tag at the end of the selection

for example a user selcts some text in content area;
Telerik.Web.UI.Editor.CommandList["MyTestButton"] = function(commandName, editor, args)
{
editor.pasteHtml('<TagBegin>');

/*some way to find end of selection ???*/

editor.pastHtml('<TagEnd>');

};

HeaderContextMenu ignoring TemplateColumns

I want to use the HeaderContextMenu for a RadGrid, but there are several TemplateColumns and they are being ignored by the HeaderContextMenu commands.

I am able to sort, group and filter by the normal BoundColumns, but if I try to do anything with one of the TemplateColumns it doesn't work. I added SortExpression and UniqueName to each of the templates, but still no dice.

Is there anything else I need to do to make it work?

Thanks

[Solved] RadDatePicker:AutoCorrect Override (othe forum posts not working)

I have read throught he forum and see that a number of people do not like the feature of the RadDatePicker auto correcting.

To rehash:

If I enter 13/12/2010 I DO NOT want the control to automatically change it to 12/13/2010.

I have tried adding the following:

    
            <telerik:RadScriptBlock runat="server">  
        
                <script type="text/javascript">  
        
                    Telerik.Web.UI.RadDateInput.prototype.parseDate = function(value, baseDate) {  
        
                        if (new Date(value) != "NaN")  
        
                            return value;  
        
                        }   
        
                </script>   
        
            </telerik:RadScriptBlock>

However, while this certainly causes the dates to no longer change it also prevents me from putting in VALID dates and prevents me from using the calendar control. I would appreciate any clarification I may be missing.

Thanks,

Calendar

[Solved] RadTextBox OnBlur

Hi,

I am trying to capitalise the text that has been input into a RadTextBox when focus is moved out of the control.

This is my code:

<telerik:RadTextBox ID="txtPostcode" runat="server" MaxLength="8">

<ClientEvents OnBlur="this.set_value(this.get_value().toUpperCase())" />

</telerik:RadTextBox>

This throws an obscure ajax javascript error when the form is first loaded:
Microsoft JScript runtime error: Object doesn't support this property or method.
This is on line 3 at

a(

this,b.EventArgs.Empty)

of the MicrosoftAjax.js that is generated dynamically by the Telerik.Web.UI assembly.

Can you tell me what's wrong?

Thanks.

Reset Column Filter Function

I have a column in my RadGrid whose visibility is dependant on a checkbox on the page. When the user checks the checkbox, the column appears. When they uncheck, it disappears. Both the checkbox and the grid are in an ajax panel. Works fine.

My problem is when the user sets a filter for the column in question and then unchecks the checkbox, the filter persists. It's not apparent to the user that data is being filtered because the column with the filter is no longer visible.

So I want to reset the column filter when the user toggles the visiblity of the column. To do this, I have the following code in my checkbox's CheckChanged event handler:

if(chkShowInActive.Checked)

{

myGrid.Columns.FindByUniqueName("IsActive").Visible = true;

}

else

{

myGrid.Columns.FindByUniqueName("IsActive").Visible = false;

}

myGrid.Columns.FindByUniqueName("IsActive").CurrentFilterFunction = GridKnownFunction.NoFilter;

myGrid.Rebind();

This doesn't seem to have any effect. The grid still filters the data. What am I doing wrong?
