Hi

I don't understand what datatype this column binds to.

I have a collection of objects with a bitmap property, when binding to the grid, nothing is displayed.

What datatype am I suppose to use? Image, Byte() ? I cant seem to find much documentation on this.

Thanks

Hello Sasa Milovic,
If you bind a DB column that contains image data (OLE container or BLOB) this column should display the image data. Also it implements resizing functionality for the displayed images.

Hello Sasa,

Thank you for the response. We confirm this as a bug, which I was able to fix right away - now the Image column displays all image types correctly. The fix will appear in SP2 in about 4 to 6 weeks. Your points have been updated for the bug report.

Hi Santosh,

For the unbound mode in new RadGridView beta you can use the following code snippet:

GridViewImageColumn column = new GridViewImageColumn();  
column.DataType = typeof(Image);  
radGridView1.Columns.Add(column);  
 
radGridView1.RowCount = 1;  
radGridView1.Rows[0].Cells[0].Value = new Bitmap(Resources.DataGridRow_pencil); 
 
You can download the Q1 2008 Beta from the link below:
<admin>link no longer valid</admin>


Please share with us your feedback on the Beta. We will use it to take the final release in the direction most useful to you.

The RadGridView also supports binding to custom objects implementing IBindingList, such as the BindingList<> generic collection.

If you have additional questions, do not hesitate to contact me.
