show pictures from a database c#.net

You can use the DataList control. The DataSource for the DataList control. I suggest dragging one onto your form. Then name it "dl" for this example. Go to the HTML source for the page, and set the control to something like this to start with:

<asp:datalist id="dl" runat="server" OnItemDataBound="dl_OnDataBinding"
      RepeatLayout="Flow" RepeatColumns="1" RepeatDirection="Vertical" EnableViewState="False">

You also need a rendering template to contain your data for each data row:
<ItemTemplate>
   <asp:ImageButton id=MyImage runat="server" BorderColor="#000000" BorderStyle="Solid" BorderWidth="5"></asp:ImageButton>
</ItemTemplate>
You will need a control in your template for your image, label, and link. I show only the image control above, but you get the idea. The cool thing about rendering templates is that you have a lot of control over the layout. A DataList is good for your application, although you could also use a DataGrid or Repeater. The DataGrid is a bit too "heavy" for your application, and the Repeater control requires more effort to use. DataList is a great choice and will give you ample flexibility in presentation.

When you look at your code-behind module, you should see a a protected variable for your control:

     protected System.Web.UI.WebControls.DataList dl;

Then, set your datasource in Page_Load (it's best to write a function for that--here, it's GetMyDatasource()):

     this.dl.DataSource = mediaStagedImagesTop.GetMyDatasource();
     this.dl.DataBind();

Then, go to the OnDataBinding function for your DataList control:

    protected void dl_OnDataBinding(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
    {...}

Here, you want to add code to populate the control. Only do so for rows containing data--you do this using this condition:
     if (e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
     {...}

In the ellipses, add code to populate your image (and other controls):

     System.Web.UI.WebControls.ImageButton imageButton = (ImageButton)e.Item.FindControl("MyImage");
     imageButton.ImageUrl = DataBinder.Eval(e.Item.DataItem, "ImageURLColumn")
     // ImageURLColumn is the column name for the ImageUrl from your DataSource

You would then set the Label and LinkButton properties from your DataSource in similar fashion.

Does this help?
