After populating RadGridView with AutoGenerateColumns = true i try to change the column header text:

RGVBBoxRecords.Columns[idx].HeaderText = headerstr[idx];
or
RGVBBoxRecords.Columns[idx].Header = headerstr[idx];

but nothing changes.

How to do it?

 

In my project I want to use a "lookup" gridviewcomboboxcolumn in the radgridview. I don't  make use of  foreign key id-values, but entity framework associations instead. Is this possible and how should this be done?

Thanks,
Thomas.

Dear all,

I'm having a slight problem with programmatically changing Themes (Office_Black, Summer, etc) for my RadControls. It works perfectly fine when doing it beforehand in xaml, and changing Themes at runtime works fine for all controls except the RadComboBox and the RadPanelBar controls- these simply don't ever change from the default Office_Black theme, while all other controls change theme just fine. Note that I have tried both using StyleManager.SetTheme() and instance.SetValue(StyleManager.ThemeProperty, theme), both of which yield the exact same result.

Here is a small project that demonstrates this.

Any thoughts on what I could be doing wrong would be much appreciated.

Cheers,

Frits Verhoef.

We need to display data which are collected from a instrument.
Does the RadControls chart support this real time data update?
Can we scale the X-axis? At the beginning, it display as 1-10 unit,
As more data collected, it display as 1-100 unit.
Thx!

Hi,

I have downloaded a trial version of Rad controls for WPF and started using it one of my projects.
Trying to use the themes provided by telerik. In some of my pages I've used RadNumericUpDown control. When I try apply Office_Blue, Office_Silver and Summer themes, this control gets disabled. Basically, the  theme gets applied but the default values of the control disappears and the control doesnt respond to any clicks. Wiith the other two themes: Vista and Office_Black the controls works fine.
Here is the code:
<telerikComboBox:RadNumericUpDown x:Name="updownStartTime" Margin="2,0,2,0" Maximum="10"                                                                               telerik:StyleManager.Theme="Office_Blue" Minimum="0" RepeatInterval="1" Width="60" Height="20"></telerikComboBox:RadNumericUpDown>

I cant understand what the problem is. I tried d same with combobox, but it's working fine with it. The themes are getting applied and the control is working fine too. Since I've just started I dont know if this problem exists with other controls and other themes too. Looks like certain combinations are not working. There no documentation available for the same too.
Also, please provide a solution to change themes dynamically.

How do you build a footer row like you have in the 2q 2009 sample in code vs. xaml???

Currently, our databinding, column configuration, and most everything else is being developed in our code behinds instead of xaml.

I noticed a Dock panel control for silverlight but not for WPF?  Can I use the silverlight control in an XBAB or WPF applications?

Is it possible to have the legend for a chart appear as a tooltip for the chart, rather than being always displayed?

I'm new to Telerik WPF RadGridView, I have question:

1. I want to archive text wraping in RadGridView, but how ?
2. Can I set custom formatting for cell value? I have column long value type, but I want to display it as duration like 01:30.
    I have writing IFormatProvider for it, but don't know how to attach it do RadGridView Column.
3. I want to display row number in RadGridView, how do I do that (example):
    No. Name
    1    A
    2    B
4. Does RadGridView support saving and loading Layout?

Thx

Hi,

We are using OnDemandLoad and binded tree with our datastructure. Howevere in certain case say if A is true then we do not want a certain node say Node1 to expand eventhough it gets data on demand i.e. only parent Node1 should be shown but no Childrens of it but at the same time we do not want to remove it from out binded datasource - in essence we need to hide them from tree.

Hope you get the problem. Please provide us ways/code lines to achieve this.

Thanks in advance,
Balaram
