which parameters should be pass for bind property of image

Question

In my application I am using following code

page1.aspx:

<asp:DataList ID="datalist" runat="server" RepeatColumns="5" RepeatDirection="Horizontal" >

<ItemTemplate>

<asp:ImageButton ID="IB_tn" runat="server" ImageUrl='<%# Bind("photo", "url1") Width="100px" Height="100px" CommandArgument='<%# Container.ItemIndex %>' />

</ItemTemplate>

<SelectedItemStyle BorderColor="Red" BorderWidth="1px" />

</asp:DataList>

 

page1.aspx.cs:

 

var objects = new JavaScriptSerializer().Deserialize<dynamic>(json);

Array arryobjects = new JavaScriptSerializer().Deserialize<dynamic>(json);

int mycount = arrobjects.Length; 

 

for (int i = 0; i< mycount; i++)

{

filename_photo = objects[i]["filename"];

url1 = objects[i]["url"];

dtlist.DataSource = listItems;

dtlist.DataBind();

Photo photod = new Photo(photo, url1);

listItems.Add(photodetails);

}

 

and create a class:

 

public class photo

{

string photo { get; set; }

string url1 { get; set; }

public Photo(string photo, string url1)

{

this.photo = photo;

this.url1 = url1;

}

}

 

this code giving me run time error:

 

[System.Web.HttpException] = {"DataBinding: 'Photos.Photo' does not contain a property with the name 'url1'."} or

[System.Web.HttpException] = {"DataBinding: 'Photos.Photo' does not contain a property with the name 'photo'."} 

 

can any one explain me what is wrong in my code?
