Hi All,

I need some help to modify "Horizontal Bar" chart created using Portlet Factory. I have following problem in my chart

1. When data is very low like 1 or 2, horizontal scale doesn't appear properly. It come like 0 0 0 1 1 1 1 1 2 2 2. As data increase it shows scale properly like(more then 3) 0 1 2 3.
2. If any Option doesn't have any data(empty), still it shows blank space for that option.  

For your reference I have attached one image file with this post.

 
Please help me to resolve this.

Thanks in advance...

Hello Telerik,
I am developing a customcontrol for radbutton .


I have a requirement to change the image of the radbutton to different image on 'Hover' operation.

public

 

 

class TngButton : TngBaseTemplateControl

 

 

 

 

{

 

 

 

static TngButton()

 

{

DefaultStyleKeyProperty.OverrideMetadata(

 

 

 

 

typeof(TngButton), new FrameworkPropertyMetadata(typeof(TngButton)));

 

}

 

 

 

#endregion

 

 

public override void OnApplyTemplate()

 

{

 

 

 

 

 

base.OnApplyTemplate();

 

 

 

 

 

 

RadButton btn = this.Template.FindName("PART_BaseControl", this) as RadButton;

 

 

 

 

 

 

ContentPresenter content = this.Template.FindName("PART_ContentControl", this) as ContentPresenter;

 

 

 

 

 

 

btn.Hover+=new EventHandler<Telerik.Windows.RadRoutedEventArgs>(btn_Hover);

 

 

}

 

 

 

 

 

 

void btn_Hover(object sender, EventArgs e)

 

{

 

 

 

 

 

 

// code to change the image at the hover .

 

 

 

 

 

 

 

}


i want to have two properties like 'originalimage' and 'hoverimage" which can be changed on mover hover action

Hi,

i have a really strange problem with the gridview and i can't figure out what the exact problem ist. my scenario: i have a usercontrol with several other controls, a combobox and a gridview. the gridview contains several columns: text-, checkboxes- and one combobox-column. the deal is when i'm selecting a value in the combobox OUTSIDE the grid, the combobox INSIDE should be updated. which works pretty good - exept for one thing. when i load the data to the grid, change 1 cell in the grid, and then select the combobox outside, i get following exception:

if i first load the data, then select any value from the combobox and change the values in the grid after everything works fine.
i have tried to "delete" the existing itemsource by setting grid.ItemSource = null before rebinding the changed data but this also provides the same exception. any ideas what i can change?
thx in advance

I am binding my chart to a DataTable.  Using the following code in the chart's constructor to display two bar series works:


However, if I replace both instances of DataPointMember.XCategory with DataPointMember.XValue, I get the following error:

InvalidOperationException - The binary operator GreaterThanOrEqual is not defined for the types 'System.Object' and 'System.Double'.

Also if I use just one series on the chart (with DataPointMember.XValue), it works fine. 

I have a business requirement to render on a map control the same data that is displayed in a GridView control.  For example, if the grid is loaded with all of the companies locations in North America, display those locations on the map.  That part is simple.  Where I have a problem is if the user filters the grid to show only US locations, they want the map to show only those locations. 

I can see that the RadGridView.Items class has a private property of CollectionView that contains the collection of the filtered items. if this collectionview were a read-only property I could just use if for my map object.

I would think that reusing the filtered data from a grid for other purposes would not be an entirely rare requirement.

Is there another way to do this that I am missing?

Thanks in advance for any assistance.

Hi,
I have some data with a big interval, for example maximum of my data is 15,962,940,000.00 and my minimum data is 185,400.00, and my other data is between this 2 data.
When I use pie chart for showing that I am getting  Value was either too large or too small for an Int32. error.
this is a part of my stack trace :


can you help me to solve this error.

Hello,

I downloaded Telerik for asp in september 2007. It was buggy and I finally turn to DevExpress (buggy but better, to my opinion).

Today, I downloaded DevExpress but was not impressed with it (I haven't found the up-down in the demo). I then downloaded Telerik for WPF. Mainly to look at the up-down. Not a big control that is hard to design but to save time and have an idea on what worth Telerik. I downloaded the trial, installed and 5 minutes after accessing the web site and try the demo of it, I found a bug in the control I need. WOW !!!
I tried to report the bug but I can't. It says many sentenses that I can't figure out in wich case I have exactly but I can't report a bug. I didn't buy it and I already downloaded something 3 years ago (is that for that reason ???). Anybody should be able to report a bug. A company that really want to improve their product would beneficiate from the greatest amount of feedbacks.

The bug is that if you click on the left of a previous entry (say you click before 1 in an entry of 12 345.67) you can "Del" delete the "1" but can't delete more. If you modifiy the text, then the delete works fine...
But they don't want to hear about it from me. They blocked me to report it. The first control I tried was buggy and I found the bug in 30 seconds of try. WPF is not new anymore. I don't really want to continue. I just don't trust them at all. Plus, they don't care of what I have found, they don't want to know they have bugs. Probably they also want to hide them to futur buyer (i did'nt try to look for the knowledge base but I suppose it is also inaccessible).

For me its clear, Telerik is not an option.

Hi,
i dont know how to achive mine problem, i got a GridView with two checkboxes Yes and No, when user click Yes, No should be Unchecked and when user clicks No, than Yes should be unchecked.


Also i need to save current row to database when something is clicked (Yes or No, cos default is none) so i need to fire an event.

Last question is how can i select current row on checkbox click ?
