Cannot see an image in RadGrid

[Andreas]

Hi All,

I am using the RadGrid and have added a GridBinaryImageColumn. The ROW gets bigger when an image is in the record (rows where there are NO image data, are lean, this is just because I defined width and height manually in order to see if something is happening once there is an image in the database).

However, although there is a larger space in the column I cannot see any picture. The database table itself has an image field. I tried to read binary date through writing a memory stream to a bitmap and this worked fine.

Working with the BinaryImageColumn doesnt show any picture. Please find below the code.

I have set HeaderText and DataField to the name of the database table field, which is 'Signature'.

I have set DataType to System.Byte

  <Columns>
        <telerik:GridBoundColumn DataField="OrderNumber" DataType="System.Int32"
            HeaderText="OrderNumber" SortExpression="OrderNumber"
            UniqueName="OrderNumber">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="ParcelNumber" HeaderText="ParcelNumber"
            SortExpression="Parcelnumber" UniqueName="ParcelNumber">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="DeliveryTime"
            DataType="System.DateTime" HeaderText="DeliveryTime"
            SortExpression="DeliveryTime" UniqueName="DeliveryTime">
        </telerik:GridBoundColumn>
        <telerik:GridBinaryImageColumn AlternateText="" DataField="Signature"
            HeaderText="Signature" ImageAlign="Left" ImageHeight="100px"
            ImageWidth="200px" UniqueName="Signature">
        </telerik:GridBinaryImageColumn>
        <telerik:GridCheckBoxColumn DataField="Retoure" DataType="System.Boolean"
            HeaderText="Retoure" SortExpression="Retoure" UniqueName="Retoure">
        </telerik:GridCheckBoxColumn>
    </Columns>

With searching thru the forum, I found the solution...

I added the RadScriptManager and registered the http handler in the webconfig and it worked

Thanks a lot for providing this forum, its really great!!!

I finally used this for the web.config

<system.web>

<httpHandlers>

   <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />

    </httpHandlers>

    </system.web>


    <system.webServer>
        <handlers>

      <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />


            </handlers>
    </system.webServer>
