RadAjaxManager & User Control JavaScript

Hi Guys,

I'm experiencing a problem and was hoping you may be able to point out if there is a way round it.

I have a radtabstrip that is dynamically loading user controls on click via the radajaxmanager.

This all works as expected except the user controls all contain javascript on them.
None of the javascript is recognised when loaded via the radajaxmanager and thus a number of controls on the page don't function correctly.

How should I be implementing javascript within a user control that is loaded dynamically via the radajaxmanager?

Thanks

Rad Grid date Picker Filter not working

HI,
We have Date Filter and Text Filter Columns, When we apply only Date filter it's filtering the records properly,
But when we trying to apply the Date filter with any other text filters then its igoring the date filter and its not persisting the current value of Date filter.
E.g.
Suppose we have three filters F1, F2 (text filters) and F3 is date filter.
Now for the first time when we apply F3 with F1, the records are filtered properly but when we apply filter F2 in addition to previous filters then its ignoring the F3 and it is not persisting the current value of F3. The records are filtered based on F1 and F2 filter even if there is F3 filter applied.

EnableDragToReorder for tabs created through client side api

Hi,

We are creating tabs on our using client side api of tab strip. We have set EnableDragToReorder for this tabstrip. However we are not able to reorder tabs using drag and drop mechanism. We are able to reorder tabs if they are predefined but it doesnt work dynamically generated tabs. Events like onclienttabdragstart, onclientreordering are also not generated in this case.

Please let us know if we need to do something different to achieve reordering of dynamically generated tabs ?

Regards,
Kiran

error with xmlhttppanel and combobox with checkboxes

I have a page with a combo(ComboBox1) in a xmlhttppanel(XmlPanel1) and also a stand alone checkbox combo(RadComboBox1). After I call XmlPanel1 and select an item from ComboBox1, then select a checkbox item from the RadComboBox1 I get an error.

I have created a very simple example to show the error. Am I doing something wrong?

Uncaught TypeError: Cannot call method 'get_checked' of null

Telerik.Web.UI.WebResource.axd: 3642

c.RadComboBox.prototype._onCheckBoxCheck=function(f){var d=f.target.nodeName;

if(d=="LABEL"){f.preventDefault();

}var h=this._findNearestItem(f.target);

var j=h!=null?h:this._extractItemFromDomElement(f.target);

if(this.raise_onItemChecking(j,f)){f.preventDefault();

return;

}j.set_checked(!j.get_checked());
Uncaught TypeError: Cannot call method 'get_checked' of null

this.raise_onItemChecked(j,f);

this._updateComboBoxText();

if(this._checkAllItemsElement!=null){this._updateCheckAllState();

}if(this._postBackOnCheck){var g={Command:"Check",Index:j.get_index()};

this.postback(g);

}};

Dock - DockPositionChanged event fires after Init

Hi,

I'm using dynamically created RadDockZones and RadDocks to represent data.
Everything is dynamically created during the Page_Init event.
Whenever a Dock is dragged to a different DockZone, I want to save its new position (DockZone) in the database.
I'm using the DockPositionChanged event for this.

However, when a Dock is dragged to another DockZone, triggering the DockPositionChanged event, the Page_Init event is fired BEFORE the DockPositionChanged event.
This means that while the new position (DockZone) of the Dock is correctly saved in the database, it's not shown until a refresh of the page.

Is there a way to deal with this without having to go throught the trouble of loading/saving the state?

Cheers,
CJ
