DataImageUrlFields doesn't work

[Mattia]

Hi
I'm trying to display an image in a GridImageColumn.
I tried with
DataImageUrlFields="FieldImgUrl"
where FieldImgUrl is a field of my object (FieldImgUrl = "/PHP/icon/accept.png")
but no image is shown

<telerik:GridImageColumn HeaderText="Field1" HeaderTooltip="Field1" AllowFiltering="false"
                       DataImageUrlFields="FieldImgUrl" UniqueName="Field1" ItemStyle-Width="16px" >
                       </telerik:GridImageColumn>

But if I write directly ImageUrl = "/PHP/icon/accept.png" it works...

<telerik:GridImageColumn HeaderText="Field1" HeaderTooltip="Field1" AllowFiltering="false"
                       ImageUrl="/PHP/icon/accept.png" UniqueName="Field1" ItemStyle-Width="16px" >
                       </telerik:GridImageColumn>

Thanks

Hi Stefania,

I tried your code and it works fine at my end. Please make sure the path set in the datasource is correct. Please check this article to know about the properties of GridImageColumn. Please check this example, in my db in the Photo path column I have the following value http://4.bp.blogspot.com/-djwhyOJyit8/T9b1PLKFdPI/AAAAAAAABHg/aG0_sSOi0_M/s1600/telerik_logo_RGB_photoshop.jpg , both DataImageUrlFields and ImageUrl works.

ASPX:

<telerik:GridImageColumn HeaderText="ImageColumn" DataImageUrlFields="Photopath" ImageHeight="100px" ImageWidth="82px">
</telerik:GridImageColumn>

<telerik:GridImageColumn HeaderText="ImageColumn" ImageUrl="http://4.bp.blogspot.com/-djwhyOJyit8/T9b1PLKFdPI/AAAAAAAABHg/aG0_sSOi0_M/s1600/telerik_logo_RGB_photoshop.jpg"  ImageHeight="100px" ImageWidth="82px">
</telerik:GridImageColumn>

​
Thanks,

I tried with a full and relative path but both didn't work.
Whereas DataAlternateTextField it works..

It should be related with the fact that I use ClientDataSource?

this is the html that I see in my page

<img  id="ctl00_ContentPlaceHolder1_HomeRadGrid_ctl00_ctl06_imgBt1Asset.Bt1" src="" title="s/n: 00201" alt="s/n: 00201"></img>

this is how I populate the grid

<telerik:RadClientDataSource ID="RadClientDataSource1" runat="server" AllowBatchOperations="true">
          <ClientEvents OnChange="LoadBigMap" OnDataParse="Parse" />
        <DataSource>
            <WebServiceDataSourceSettings>
                <Select Url="load_map.asmx/GetHomeData" RequestType="Post" DataType="JSON" ContentType="application/json; charset=utf-8" />
            </WebServiceDataSourceSettings>
        </DataSource>
        <Schema>
            <Model>
                <telerik:ClientDataSourceModelField FieldName="Id" DataType="Number" /> <telerik:ClientDataSourceModelField FieldName="Bt1ImgUrl" DataType="String" />
                <telerik:ClientDataSourceModelField FieldName="Bt1ImgToolTip" DataType="String" />
...
            </Model>
        </Schema>

    </telerik:RadClientDataSource>

function Parse (sender, args) {
              var data = args.get_response().d;
              for (var i = 0; i < data.length; i++) {
                  if (data[i].Code != "") {
                      data[i].Bt1ImgUrl = "http://4.bp.blogspot.com/-djwhyOJyit8/T9b1PLKFdPI/AAAAAAAABHg/aG0_sSOi0_M/s1600/telerik_logo_RGB_photoshop.jpg";
                      data[i].Bt1ImgToolTip = "s/n: " + data[i].Bt1Asset.Bt1.Code;
                  }
              }
              args.set_parsedData(data);
          }

<telerik:RadGrid ID="HomeRadGrid" runat="server" ClientDataSourceID="RadClientDataSource1"

                EnableEmbeddedSkins="False" AllowPaging="True" AllowSorting="True" AllowFilteringByColumn="True"

                Skin="MySkin" ShowGroupPanel="True" PageSize="10">

                <PagerStyle Mode="NextPrevAndNumeric" />

                <MasterTableView AutoGenerateColumns="False" ClientDataKeyNames="Id, Bt1Attribute.Latitude, Bt1Attribute.Longitude, BaloonIcon"

                    HierarchyLoadMode="Client" GroupLoadMode="Client"  EnableGroupsExpandAll="true">       

<telerik:GridImageColumn HeaderText="Field1" AllowFiltering="false" AllowSorting="false"

                            DataImageUrlFields="Bt1ImgUrl" ItemStyle-Width="16px"  DataAlternateTextField="Bt1ImgToolTip"

                            HeaderTooltip="Field1" UniqueName="Field1">

                            <ItemStyle Width="16px"></ItemStyle>

                        </telerik:GridImageColumn>
