DataGrid with Images

Set the Image.ImageURL property for your image control from the database field in the itemdatabound event of the datagrid :) Sorry it's a little brief much rush :)

Hello

I have the same question about using Images in a datagrid.
I want to bind the image dynamically in ItemBound event.
I am having trouble figuring it out. Below is my code:

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
System.Web.UI.WebControls.Image imgDaily = CType(e.Item.Cells[2].Controls[1],System.Web.UI.WebControls.Image);



if(e.Item.Cells[2].Equals("1"))
imgDaily.ImageUrl = "./Images/yes.jpg";
else if(e.Item.Cells[2].Equals("1"))
imgDaily.ImageUrl = "./Images/no.jpg";
}

I think the CType is a VB format. I need to write the code in C#,
somebody pls help me.

Thanks
Sandy

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
System.Web.UI.WebControls.Image anImagine ;
if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item )
{
anImagine = ((System.Web.UI.WebControls.Image)e.Item.Cells[1].Controls[1]); anImagine.ImageUrl="icons/" + e.Item.Cells[0].Text.ToString() + ".gif";

I have do the same but it cause error
"Specified cast is not valid." at the line code.

anImagine = ((System.Web.UI.WebControls.Image)e.Item.Cells[1].Controls[1]);

I want to display images in the datagrid of the asp.net framework 1.1.

private void dgCategory_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
		{
			System.Web.UI.WebControls.Image img;
			if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
			{				
				img = ((System.Web.UI.WebControls.Image)e.Item.Cells[3].Controls[0]);
				img.ImageUrl =@"D:\ACCP2005\Semester III\ASP.Net\Excerices\ASP Examination\Images\baokhac24-04-08_pic1.gif";
			}
		}

but it cause error "Specified cast is not valid"
at the line code img = ((System.Web.UI.WebControls.Image)e.Item.Cells[3].Controls[0]);

try like this for gridview same will work for any databoundcontrol with small changes

<asp:TemplateField >
        <ItemTemplate >
            <asp:Image ID="Image1" runat="server" ImageUrl ='<%# "~/Images/"+Eval("filenamefromdb") %>' />
        </ItemTemplate>
        </asp:TemplateField>

try this one dear!!!!!!!!!!!!

<asp:DataList ID="dlList" runat="server" DataKeyField="ID" 
                onitemdatabound="dlList_ItemDataBound">
                <ItemTemplate>
                    <table border="0" cellpadding="0" cellspacing="0" width="100%">
                                <tr>
                                    <td align="center">
                                        <a href='<%#Eval("Link") %>' target="_blank">
                                            <%-- <img src="WebAdmin/LogoHandler.ashx?ID=<%# Eval("ID") %>" style="border: 0px solid white" />--%>
                                            <asp:Image ID="Image2" runat="server" />
