Hi,

My issue is that I need to change the column name(following format "Remove first character and after third character insert colon") of the gridview (which is bound with XMLTextReader), without directly changing the XML file. I am required to change the column name dynamically at runtime.

Performance.xml

XML

<Performance>
     <Departments>
            <Heading>FS</Heading>
            <S0015>1</S0015>
            <S0020>2</S0020>
            <S0025>5</S0025>
            <S0030>5</S0030>
            <S0035>6</S0035>
     </Departments>
     <Departments>
            <Heading>BS</Heading>
            <S0015>0</S0015>
            <S0020>3</S0020>
            <S0025>5</S0025>
            <S0030>1</S0030>
            <S0035>3</S0035>
       </Departments>
</Performance>

Heading   S0015   S0020   S0025   S0030   S0035
FS        1       2       4       5       6
BS        0       3       5       1       3

Required Format:"Remove first character and after third character insert colon"(S0015-- 00:15)

Heading   00:15   00:20   00:25   00:30   00:35
FS        1       2       4       5       6
BS        0       3       5       1       3

Kindly look on this issue.

Hi, I got how to change the column name, Can somebody help me out regarding changing the format ( Truncating first character and inserting colon after third character).

String Manipulation?

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            string x = e.Row.Cells.Count.ToString();
            int y = System.Int32.Parse(x);
            for (int i = 2; i < y; i++)
            {
                e.Row.Cells[i].Text = "xxx";

            }
        }
    }

One way to do that is as follows:

C#

var bookquery = from k in XElement.Load(MapPath("book.xml")).Elements("book")
                join m in XElement.Load(MapPath("Library.xml")).Elements("Library")
                on (String)k.Element("bookid") equals (String)m.Element("bookid")
                select new bookclass
                {
                    bookid        = (String)m.Element"bookid"),
                    Title         = (String)k.Element("title"),
                    AuthorName    = (String)k.Element("author").Element("first-name"),
                    AuthorSurName = (String)k.Element("author").Element("last-name"),
                    Price         = (String)k.Element("price")
                };
GridView1.DataSource = bookquery;
GridView1.DataBind();

Could you please post in C#.Net.

Your code block formatting was way off, so I fixed it.

Use the Insert() function to put the colon in:

C#

e.Row.Cells[i].Text = e.Row.Cells[i].Text.Insert(3,":");

Use the SubString() function to do the truncation:

C#

e.Row.Cells[i].Text = e.Row.Cells[i].Text.Substring(1);

You can combine these two functions into a single statement:

C#

e.Row.Cells[i].Text = e.Row.Cells[i].Text.Insert(2,":").Substring(1);
