Hi,
Thanks for the great work.
Am very new to telerik Rad Charts.
I would like to Create 2 Bar Charts on 1 windows Form using VB.net with Data coming from a Database.

I am looking at creating SQL Statements for each of these 2 Charts with the X and Y axis for the Charts in mind.
i.e Select Products, Prices from ProductSale

Kindly provide a sample example that can enable me pick data from the Database and Bind this Data to the Bar Charts.
I have tried but havent been able to get a newby example of this kind from the forum yet

Thank U.





 

Hello

I created a new form, added a RadGridView to it, and populated it using a query containing a UNION statement.



Even with the ReadOnly=false, when I changed a cell's value and clicked elsewhere, a "Data Exception" message saying "Column 'a' is read only." poped up. I put my UNION statement in a view, called the view, and everything worked as expected.

Hi,

We are using Telerik winform version 2009.3.9.1203. In that, we have used Gridview with the Grouping. And, we need to give the ability to add a new row at any row position. But, when we code that, the grouping is not reflecting properly. Because of which the newly added row is always go to the top.

Attached is the sample screenshot for your reference.

Please let me know, the solution for this.

Is there any way to set in command bar any control acceptable by command bar, like drop down list, anchored to the right side of the bar?

The command bar in the picture attached is stretched on the whole width of its parent control and is resizing with its parent control together.

Any help is appreciated.

(*I thought I posted this yesterday, but can't find it*)

I created a usercontrol that has a panel. I made the panel with rounded corners, just like the documentation. However. You can still see the square behind the rounded corners. I tried making them transparent, but no luck. See attached img. Suggestions on getting rid of the square in the back?


Thanks!

Hi, 
  I am evaluating gridview for winforms. I tried but couldnt get it workings ...here is that couple of things i would like to do (very keyboard intensive data entry) all operations performed using keyboard,no mouse at all
  1. Validate a cell after data entry and if validation fails keep the focus in the same cell . escape should remove that row
   2. after entering data for the last cell,add a new row and keep focus on the first cell in the newly added row and repeat this.

Any help is greatly appreciated.
Thanks
