[saurabh]

we need few unique functionality in Telrick Grid. I don't know this kind of functionality exist in Trlerick GridView control or not. if yes please send a sample application for it. I have attached a details document please find the attachment.

A selected row/column should highlight be highlighted, even when a specific cell is being edited:

 Multi-select should be supported.

 When multiple cells are selected, numeric pad entry should update cells:

 When a single cell is in edit mode, numeric input should only be allowed, to 2 decimals (similar to calendar control:

 Backspace should clear values.

Users should be able to click a column header and select an entire column

Hello Vlad,

I have checked your demo and need to describe you some things related to my requirement and the problems i am facing with:

Requirements:
1. The user can be able to select an entire row by using keyboard or mouse.
2. The user can be able to select an entire column or multiple cells by using keyboard or mouse.
3. The user can be able to select a group of cells my using mouse. (Currently the problems is we need to click on a particular cell to select/deselect. I need this functionality over mouse move.
4. When user can select his selection, he can enter the values in selected cells.
5. These all requirements should supprort with grouping.

Problem:
I am facing a single problem of An unhandled exception has occured with the following details, whenever i select the telerik grid in designer mode. Due to this i am unable to work in designer.

I am attaching some imaged for my requirement. Please have a look on those and let me know if we can have any kind of online meeting and have a discussion to make you understand my problem and requirements. If you are all set with my requirement, please send me detailed steps to achieve this task, and if possible, please provide me a demo application.

Thanks and Regards

Hi Ashish,

Thank you for your interest in our Silverlight controls.

The cell selection mechanism that will be introduced with our upcoming release will cover most of your requirements. Unfortunately features like column selection and editing of the selected cells will not be supported but hopefully we will be able to implement them for the first service pack of Q2.

Selecting entire row with mouse, selecting cells with mouse and/or keyboard, selection in grouped mode will be supported.

In regard to the exception, it is most probably cause by old Silverlight installation. Do you have the latest Silverlight Tools and runtime? Another information that might be helpful is the version of Visual Studio that is being used.

Greetings,
Milan
