Questions on UI for ASP.NET AJAX Forum

I've been searching the documentation and the forum for a while for this, but haven't been able to find any solid information...

I have an object which contains some fields and a dictionary - I want to bind each value in the dictionary to a column in a radgrid. I don't know what these keys/values will be until the item comes back, and they'll change depending on the source of the query.

I can create the columns dynamically without a problem, but I need a way to bind their DataMember to the dictionary...what's the best way to achiever this?

class ItemQueryData

{

public int ItemId { get; set; }

public String SomeProperty { get; set; }

public Dictionary<int, Object> Values;

}

private void AddRefColumns()

{

foreach (KeyValuePair<int, String> f in HeaderColumns)

_grid.Columns.Add(new GridBoundColumn() { DataField = "Values[" + f.Key + "]", HeaderText = f.Value });

}

myChart.SkinsOverrideStyles = false;

myChart.CustomPalettes.Add(myPalette);

myChart.SeriesPalette = myPalette.name;

But nothing seems to work.
Any Ideas ?

A way to delay the firing of OnAjaxRequest?

Hi all,

I'm a complete beginner with Telerik so I hope I explain this right.

I have a RadMenu set up where you can mouseover a RadMenuItem and it calls an AJAX method to fetch a description, which then gets displayed in a label at the bottom of the menu. It's something along the lines of this Telerik demo with the map, except the event is onmouseover and not onclick. This all works great.

However, you can imagine if someone is mousing down a menu of say 20 items, you only want the Ajax call to fire when the user rests on a particular menu item e.g. for say at least 0.25 seconds. That way I'm not sending 20 Ajax calls off unnecessarily.

Is there a way to delay the firing of the Ajax call?

Filter throwing Error when filtering Grid Column that includes NULLs

Hi,

I have a RadFilter control hooked up to do advanced filtering on a RadGrid. When attempting to apply a filter on a column which contains NULLS in the DB, I get the infamous "Object reference not set to the instance of an object" error. Since I cannot change my database structure, and the Nulls are required, is there anything I can do to allow my RadFilter to filter on these columns?

Best Regards,
Landon

Use Aggregate Sum Elsewhere

I searched around for a solutions but I'm not even sure if my description/search terms were well defined enough. Here is what I have. Two Grids on a page. They are for the most part very unlike data so they cannot be in the same grid. However, there is one column in each that I am using the Aggregate Sum. What I would like to do is take the Aggregate Sum from one table and add it from a second table and write that off to a textbox/variable for use elsewhere.

Hopefully that makes sense. I tried screwing around with the footer, but I couldn't seem to find the right combination to grab the information from the footer.

Thanks,

Richard
