RadGridView AggreagateFunctions: CalculateAggregates

Hi Telerik,

We are using RadGridView's -Column- AggregateFunction. We have disabled the Group Panel and Group Footer.

We are binding to an ObservableCollection of objects which implement INotifyPropertyChanged.

We have noticed that calling CalculateAggregates() updates the underlying values in the AggregatesResults collection after each call to CalculateAggregates(), however, the RadGridView's aggregate footer row in the UI will only ever update the values after the first call; subsequent calls will not update the value in the footer row.

In other words, the underlying AggregateResults values are always updated when calling CalculateAggregates(), however, the results on the screen in the RadGridView's aggregate footer row will remain as only the first updated calculated aggregate values, and will ignore displaying any further updates to the underlying aggregate values.

We have also called .Rebind() with the same effect.

XAML:

<telerik:GridViewDataColumn DataMemberBinding="{Binding aDatum}" Header="Data" DataFormatString="{}{0:,##0;(#,##0);0}" IsReadOnly="True" FooterCellStyle="{StaticResource GridViewFooterCellStyle}" HeaderTextAlignment="Center">
<telerik:GridViewDataColumn.AggregateFunctions>
<telerik:SumFunction ResultFormatString="{}{0:#,##0;(#,##0);0}"/>
</telerik:GridViewDataColumn.AggregateFunctions>
</telerik:GridViewDataColumn>

Style:

Could you please give direction on this issue? Why does the aggregate only refresh the RadGridView's footer row the first time calling CalculateAggregates() and not on subsequent calls to this function?

Kind regards

Question about using RadDataForm to edit grid data like a popup.

I found an example of using RadDataForm like a popup on these forums. Is there a way to add a button in the upper right to cancel and close the popup?

It looks as if in the ERP example you are really placing the DataForm in a new window (RadWindow) to accomplish this. Is that the only way or is there an easier way to make this happen?

Thanks..

Issue with flat themes

I'm using RadGridView, which is set to merge cells vertically, and rows have detail template.

with this configuration, when a flat them is applied (like VisualStudio2013Theme or Office2016Theme), the merged cells are displayed incorrectly over the row template. But if I use other themes (like Windows7Theme or Office_SilverTheme) it look like great!

Screen shots of both views are attached.

Is this a bug? and is there any workaround to fix it?

thanks

Tab Item with no scroll

Hi Team,

Please help me for the following.

We have few tabs.

Eg :

TabA TabB TabC

Inside TabC based on some functionality we will open the tab dynamically using PRISM.

Now dynamically I can open 'n' number of tabs.

Now scroll will come in the top so that all the tab items will move accordingly.

Now,

I need to freeze the Parent Tab i.e. TabA , TabB , TabC

Scroll should come for only the tab which is opened dynamically.

Regards,

Veeraguru S

[Solved] Need some advice with schedule view refresh

Hi.

I have this problem: when I switch between day/week/month views without any filtering it works just fine.

But if I add any single resource as filter, some refresh is missing.

This worked before, so obviously I broke some synchronization messaging.

Attached is a short video of this behavior (changed the mp4 extension to png so it is accepted...).

What I need is some pointing into the right direction.

There is some stuff going on behind scenes: I already have special slots beahviour, I added my own control with some enhanced calendar functioning (just wrapped radcalendar and added a few more controls...), have drag and drop implemented to update a few pieces of info in the assessment.

But somwhere in the way I broke the refreshing, it seems...

Thanks in advance.

Issue with column size while loading

Hi,

I'm experiencing a visual issue where the column width of my columns in a RadGridView is very small while the RadGridView is loading. In my product, it give sort of a "jitter" feel when you load the application. I've attached to this post 3 pictures, the first step where we see the shrunken header columns, the second step where the columns grows but it creates a scrollbar, and the final step where I get the desired visual.

Overall it takes 90ms for the datagrid to settle to the final step. I am not very concerned about the scrollbar as I don't observ this in my final application (probably due with a different layout than this simple test of a GridView in a Grid).

I include a link to a very minimalistic project that can let you recreate the issue : https://drive.google.com/file/d/0B9yNrE596_TZeTBzd241OFhZMWM/view?usp=sharing

This gives our application a very janky feel, I hope it's just a matter of me not having setup the width of the columns properly or something like that!

Thanks in advance!

How to resize the width of EnumFlagEditor to the width of RadPropertyGrid

Hi,

I need to resize the width of FlagEnumEditor whenever propertyGrid is resized, i want to set the new width of propertyGrid to the FlagEnumEditor.

Because if I wont set the propertyGrid width to it, then when more items are checked in FlagEnumEditor its width exceeds the propertyGrid limits and a horizontal scrollbar starts appearing, i dont want a scrollbar, i just want to restrict the FlagEnumEditor's width to the width of PropertyGrid specially when PropertyGrid is resized.

Regards,

Tayyaba
