wish helps you I have a code for a gridview feild that displays a title, and evaluates a hyperlink (link) in a way that if there is a value in the link, that title will be clickable and the title will redirect you to the link.. as followed: , Try this
<asp:HyperLink ID="Title"  runat="server" Text='<%# Bind("Title") %>'  NavigateUrl='<%# Eval("link") %>' style='<%# Eval("link").ToString()!=""? "text-decoration:underline;color:Blue;":""%>'></asp:HyperLink>

foreach (GridViewRow gr in gridDetaljiNarudzbe.Rows)
{
    DropDownList drop =  gr.FindControl("DropDownList1") as DropDownList;
    drop.Items.Add(new ListItem("test"));
}
protected void gridDetaljiNarudzbe_RowDataBound(object sender, GridViewRowEventArgs e)

How can I calculate % of 1's each row in asp gridview and display inside template field label?

around this issue You can loop all the cells in the RowDataBound event and check the data source for 1 values and calculate the percentage.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //check if the row is a datarow
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //cast the row back to a datarowview
        DataRowView row = e.Row.DataItem as DataRowView;

        decimal NoOfOnes = 0;
        decimal NoOfColumns = e.Row.Cells.Count - 1;

        //loop all the columns and find the 1's
        for (int i = 0; i < NoOfColumns; i++)
        {
            if (row[i].ToString() == "1")
            {
                NoOfOnes++;
            }
        }

        //find the label in the current row
        Label lbl = e.Row.FindControl("myLabel") as Label;

        //display results
        lbl.Text = string.Format("{0:N2}", (NoOfOnes / NoOfColumns) * 100);
    }
}

I wish this helpful for you I am trying to dynamically create a template field which has an item template consisting of a hyperlink field. Trying to recreate the below code in the backend asp.net code: , Have a look on the below code.
TemplateField customField = new TemplateField();
customField.ItemTemplate = new GridViewTemplate(DataControlRowType.DataRow, "FirstName", ControlType.HyperLink);
customField.HeaderTemplate = new GridViewTemplate(DataControlRowType.Header, "First Name", ControlType.Label);
gv.Columns.Add(customField);


 public class GridViewTemplate : ITemplate
    {
        private DataControlRowType templateType;
        private ControlType controlType;
        private string columnName;

        public GridViewTemplate(DataControlRowType type, string colname, ControlType contType)
        {
            templateType = type;
            columnName = colname;
            controlType = contType;
        }

        public void InstantiateIn(System.Web.UI.Control container)
        {
            switch (templateType)
            {
                case DataControlRowType.Header:
                    Literal lc = new Literal();
                    lc.Text = "<b>" + columnName + "</b>";
                    container.Controls.Add(lc);
                    break;
                case DataControlRowType.DataRow:
                    WebControl firstName = null;
                    switch (controlType)
                    {
                        case ControlType.Label:
                            firstName = new Label();
                            break;
                        case ControlType.HyperLink:
                            firstName = new HyperLink();
                            break;
                        default:
                            break;
                    }
                    firstName.DataBinding += new EventHandler(this.FirstName_DataBinding);
                    container.Controls.Add(firstName);
                    break;
            }
        }

        private void FirstName_DataBinding(Object sender, EventArgs e)
        {
            GridViewRow row = null;
            switch (controlType)
            {
                case ControlType.Label:
                    Label l = (Label)sender;
                    row = (GridViewRow)l.NamingContainer;
                    l.Text = DataBinder.Eval(row.DataItem, "FirstName").ToString();
                    break;
                case ControlType.HyperLink:
                    HyperLink l2 = (HyperLink)sender;
                    row = (GridViewRow)l2.NamingContainer;
                    l2.Text = DataBinder.Eval(row.DataItem, "FirstName").ToString();
                    l2.NavigateUrl = "https://www.google.com";
                    break;
            }
        }
    }
    public enum ControlType
    {
        Label = 1,
        HyperLink = 2
    }

How do you restrict a Template Field width inside a GridView?


Tag : html , By : John Studdert

this one helps. I need help restricting the 'Link target' column inside this gridview. If a long URL string is entered the page will stretch outside of the panel and give the webpage a deformed look. , Try to add the following css class to hlLinkTarget and lbLinkTarget:
    .truncate {
        width: 150px; /* set the desired width */
        display: inline-block;
        white-space: nowrap;
        overflow: hidden;
        text-overflow: ellipsis;
    }
