Hello,
I am using ReadXML to load a dataset and then use a datagridview table.

How do I only display 1 or 2 columns in that datagridview instead of all the columns? and also to change the header text?

all this is on page load

thanks!

        private void viewStudents_Load(object sender, EventArgs e)
        {
            studentDataSet.ReadXml("C:\\StudentList.xml");
           
            studentGridView.DataSource = studentDataSet;

            studentGridView.DataMember = "student";
           
           
        }

Hi

Add this function:

        private void DoDataGridViewSetup(int[] showing, string[] headerText)
        {
            DataGridViewColumnCollection gridColums = studentGridView.Columns;
           
            foreach (DataGridViewColumn column in gridColums)
            {
                column.Visible = false;
            }

            for (int i=0; i < showing.Length; i++)
            {

                gridColums[showing[i]].HeaderText = headerText[i];
                gridColums[showing[i]].Visible = true;
            }
        }

As parameter You give an array containing the columns you want to show - fx. nr 0 and nr 4.
Also You parse a string array containing the header text you want for the columns to show.

I beleve this solves your problem.

Kaj,
I will give that a try soon as I get him tonight and will let you know. Looking at the code though, it seems like it will solve it.

Thank you!

Hey Kaj,

I added the code as a seperate function. however, how do I call the function?

private void viewStudents_Load(object sender, EventArgs e)
        {
            studentDataSet.ReadXml("C:\\StudentList.xml");
           
            studentGridView.DataSource = studentDataSet;

            studentGridView.DataMember = "student";
           
        }

        private void DoDataGridViewSetup(int[] showing, string[] headerText)
        {
            DataGridViewColumnCollection gridColums = studentGridView.Columns;

            foreach (DataGridViewColumn column in gridColums)
            {
                column.Visible = false;
            }

            for (int i = 0; i < showing.Length; i++)
            {

                gridColums[showing[i]].HeaderText = headerText[i];
                gridColums[showing[i]].Visible = true;
            }
        }

Hi Jason

If You always are interrested in  - say column 2 and 4, and the headings should be Name and Phone Number. You could change the code to:

private void viewStudents_Load(object sender, EventArgs e)
        {
            studentDataSet.ReadXml("C:\\StudentList.xml");
           
            studentGridView.DataSource = studentDataSet;

            studentGridView.DataMember = "student";
 

           int[] showing = {2,4};
           string[] heading = {"Name","Phone Number"};
           DoDataGridViewSetup(showing, heading);
           
        }

        private void DoDataGridViewSetup(int[] showing, string[] headerText)
        {
            DataGridViewColumnCollection gridColums = studentGridView.Columns;

            foreach (DataGridViewColumn column in gridColums)
            {
                column.Visible = false;
            }

            for (int i = 0; i < showing.Length; i++)
            {

                gridColums[showing[i]].HeaderText = headerText[i];
                gridColums[showing[i]].Visible = true;
            }
        }
