Hello,

If the field in your DataTable is byte array all you need to do is to set DataMemberBinding to point to this field.

Hi,

You need to set only property/field name for the Binding - for example:

Dim colum As New GridViewImageColumn

colum.DataMemberBinding = New Binding("YourProperty")

RadGridView1.Columns.Add(colum)

i tried to bind a gridviewimagecolumn with the column of datatable  but was imposible that gridviewimagecolumn display the images,
when i bind the column that has the image in byte format with a gridviewdatacolumn in the cells display the image in byte format but when i bind with the gridviewimagecolumn the image doesnt appear, here is the code:

 

Dim column As New GridViewDataColumn

 

column.DataMemberBinding =

New Binding("IDENTFICACIN")

 

RadGridView1.Columns.Add(column)

 

Dim columNombre As New GridViewDataColumn

 

columNombre.DataMemberBinding =

New Binding("NOMBRE")

 

 

Me.RadGridView1.Columns.Add(columNombre)

 

 

 


Dim
columApellido As New GridViewDataColumn

 

columApellido.DataMemberBinding =

New Binding("APELLIDO")

 

 

Me.RadGridView1.Columns.Add(columApellido)

 

 


Dim
columImg As New GridViewImageColumn

 

columImg.DataMemberBinding =

New Binding("BL_FOTO")

 

 

Me.RadGridView1.Columns.Add(columImg)

 

RadGridView1.ItemsSource = data.Tables(0)

as you can see in the attach image the images doesnt appear in the gridviewimagecolumn of the radgridview
the binding  of the rest columns work prefect but althought i follow your recomendation about the binding with the gridviewimagecolumn it doesnt work

Please help me!!!
