I have a DataList control on a page. Inside ItemTemplate I have an Image and a Label control. The page get the imageurl from an sql query. The images those are shown in the image control have variable width and height. I want to set it to 160x100(wxh). I can calculate the width ratio and height ratio and have it not increased to more than 160x100.
Not sure how can i resize image control width and height programatically, for each item in datalist.
You can resize image on ItemDataBound event. Try below code.
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
// get image option if in grid or from datasource using DataBinder.Eval()
Image im1 = (Image)e.Item.FindControl("Image1");
im1.Width = "Your Width";
im1.height = "Your Height";
}
}
