Hi
I am developer from Microsoft. We are currently using silverlight version of telerik Grid.
I was surprised to know that there is no support for dynamic data in Grid.
What i mean  by dynamic data is "DataSource where columns (name, type)  are not known untill Run Time"
I was able to create columns at runtime but unable to create new row and assign data to row's cells.
Can you guys suggest me any alternatives.

Thanks in Advance

Thanks for the quick response... pseudo DataTable Class (Lightweight DataTable) will help in my scenario. But it is kind of workaround and i guess it uses reflection internally which i wanted to avoid due to performance reasons.

I was just wondering  why am i not able to create a row programatically and assign data into the cells? I am very new to the silverlight GridView, that is why i might be missing something in my code...pasting the code below for reference

if

 

 

(data != null && data.AttributeDataRows != null)

 

{

 

 

    foreach (AttributeDataRowDTO attRow in data.AttributeDataRows)

 

    {

        row =

 

new GridViewNewRow();

 

 

 

        foreach (AttributeDataDTO attCol in attRow.AttributeColumns)

 

        {

            row.Cells[columnDetail[attCol.Code].ColumnIndex].Content = attCol.Value

 

;

 

        }

        radGridView.Items.Add(row);

     }
}

Here, after creating a new row, its Cells collection is by default empty...i mean there are no cells in the row...so when i am accessing the cell by passing columnindex, it is giving exception.

All i want to know is how to set data of a particular cell of a row having a particular column.

Thanks,
Supriya Naik

Hello,

No, the DataTable will not use reflection - you can check the code.

In Silverlight (and WPF) world, advanced virtualized items controls similar to RadGridView with container recycling will not allow you to work directly with UI - you can use MVVM pattern to create your own model of data and assign this to the grid.
