[Solved] TargetType for the RadGridView.ItemContainerStyle

Hi,

I've to set the background of a cell to a special color. I used the GridViewColumn.CellTemplate.

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<Grid Margin="0" Background="{Binding Converter={StaticResource MyFirstConverter}, UpdateSourceTrigger=PropertyChanged}">

<CheckBox IsChecked="{Binding ShouldDisplayCalendar, UpdateSourceTrigger=PropertyChanged}" HorizontalAlignment="Center" IsEnabled="False" />

</Grid>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

My color works, but it doesn't use the whole size of the column. It's because the Grid doesn't take the full size of the column. I found that this is even present with ListView. A workaround is to set the to set HorizontalContentAlignment to stretch through the ItemContainerStyle.

I found example of that for ListView:

<ListView.ItemContainerStyle>

<Style TargetType="ListViewItem">

<Setter Property="HorizontalContentAlignment" Value="Stretch"/>

</Style>

</ListView.ItemContainerStyle>

My only problem is to find the "TargetType" I should put for the RadGridView:

<telerik:RadGridView.ItemContainerStyle>

<Style TargetType="??????">

<Setter Property="HorizontalContentAlignment" Value="Stretch"/>

</Style>

</telerik:RadGridView.ItemContainerStyle>

Could you tell me what I need to put here?

Thank you

Live zooming/scrolling?

When zooming or scrolling in a chart, the chart updates only after the mouse dragging the scrollbar/scrollbar handle is released. Is "live" chart updating during scrolling/zooming supported?

RadGridView Header Style Problem

Hello,

I am a designer and have recently been attempting to style the RadGridView column headers, but I am experiencing some issues. I have attached a PNG screenshot of the issue I am having.

When I modify the Gradients on the "GridViewHeaderCell" style, all the fields that contain data change to the new style. However, the leftover area that extends to the right retains the default style.

I modified all of the other color option that exist in the GridViewHeaderCell style with no success. I have also changed all colors that exist on the "GridViewHeaderRow" style, but this still has no effect on the Grid. I think I have changed the styles of every component that the RadGridView holds, but nothing has an effect on the portion of the datagrid that extends to the right.

Any suggestions or ideas on what may be causing this?

Thanks very much.

Problem with xml namespace.

Hello to all.
There are many days that I struggle with this problem, but without any results.
I'm trying to make a small GAUGE, but I always get the same error when I use it in another application outside of Visual Studio.
This thing only happens when I use usercontrol and not when I use it in an application.
The error that is plaguing me is:
The tag "RadialGuage" does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'

Visual Studio does not by any error during compilation.
someone tell me what is it? or where I am wrong?

Thanks in advance.

[Solved] Spline Addvalues

Hello I was wondering if there is funcionality in the chart or if I have to it myself

My collection looks like this
Month | Value
1        |    10
2         |    10
3         |    5
4         |   15

I want the chart to display the following
1         | 10
2         | 20
3          | 25
4          | 40

Now I can do these calculations somewhere in my code before binding. But then I would have to add properties. because the tooltips should show the collection values.

Prevent Linear gauge from stretching to horizontally

I am getting a strange behaviour when resizing the linear gauge, when I scale it vertically, the scale increases it's width, even though other elements only increase it's height.

Let me know if you need a source code for that.

Docking with multiple windows (defect)

I installed the Beta (Q1 2010) and was using the Docking feature in the Docking/FirstLook demo. If I pull out the control (floating window) and try to drag it onto another monitor, it disappears. For example, it will show half of the floating window if dragged in between monitors (see 1st screen shot).

After this happened, there seems to be an invisible area that floating windows can occupy (see 2nd screen shot).

If you start the demo app on the 2nd monitor, then try to float the window, it disappears right away.

[Solved] GridView - load data on demand

Hello All.

We have a wpf client application (xbap) with a custom Grid which display billions of records.
We implemented data load on demand, when we only fetch (load) the current page into the client.
We also support sorting and filter on the entire data at server side, and filter data for our excel like filters from all the records.

We would like to move into telerik wpf controls, what is the way to achieve such a behavior using telerik wpf controls?

Thanks
Roee
