On page load i bind data to the combobox control but if the user selects the ShowMoreResults arrow
down button to load more items(even though i display all items) it appends the same amount of items
to the box without clearing the original binded items. even though when the rcboSearch_ItemsRequested is launched it is set to clear the combobox and
indeed stepping through the code it says it has the output on screen is that
the page load data is mixed with the new data.
note if the user starts to type into the combobox the results get cleared.
the problem is only when i append data on page load and select ShowMoreResults
arrow which seems to be present even though there shouldnt be any more results to load,
this triggers rcboSearch_ItemsRequested and adds the same amount of data
as page load to the data already there

hi, is there a way to simulate a treenode click event from the client side (from javascript)?
e.g. I can do the following in the javascript on the client side:
var treeView = $find("<%=RadTreeView1.ClientID%>");
Is there a way to fire a node click event from the javascript?
Thanks,
dbi

I've done this in a desktop project, but I can't for the life of me figure out how to do this in webforms?
I have data unioned together so it can be displayed in a pivot grid
Date | Property | Value
1/1/13 | AAA | 74
1/1/13 | BBB | 62
2/1/13 | AAA | 42
2/1/13 | BBB | 12
2/1/13 | CCC | 14
3/1/13 | AAA | 16
x | series | y
Which works fine, I was hoping to display this in the chart, so that we can allow users to alter the graph live based on the pivot grid.
I tried HighCharts but I'd have to run multiple queries to try and separate out x-axis and then the series,
RadCharts is the only way I've been able to display the data in a chart thus far, but the amount of data means that the chart is so small its pointless.
Forgive the obfuscation, you can't tell much from the graph anyway but has to be done!

How can I keep the date header in TimelineView fixed? i.e. so that it doesn't scroll vertically with the content.
When there are many rows, you scroll down and the header disappears so then you can't see the dates for each column.
