grid view selected row data

i am getting the data from gridview on rowcommand event by the following code

pro开发者_开发技巧tected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "editproject")
    {
        string rowindex = e.CommandArgument.ToString();
        int index = int.Parse(rowindex);
        GridViewRow row = GridView2.Rows[index];
        Label6.Text = row.Cells[1].Text;
    }
}

but it would give only the data of the field that is visible in gridview row .how can i get the field that is not visible but bound to the gridview.

You can't get the value that you set to invisible because these were not rendered at the client side and can't be grabbed on the server side.

Alternatively you can store the value in hidden field and then you can get it from hidden field.

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{   
    MessageBox.Show(dataGridView1.SelectedRows[0].Cells[0].Value.ToString ());
}

You can,t get the invisible bound elements but you can get the value from data source .For example you save data in data table which assigned to grid .Store this data table in view-state and on row command get data-key of that row and retrieved value through data table

You can get a command-like button which is invisible in the gridview, just look at this:--- False visibility of button requires you to have changed the property EnableEventValidation="False" on the page directive in default.aspx

private void grd_bind()
{
    SqlDataAdapter adp = new SqlDataAdapter("select* from tbbook", ConfigurationManager.ConnectionStrings["cn"].ConnectionString);

    DataSet ds = new DataSet();
    adp.Fill(ds);
    GridView1.DataSource = ds;
    GridView1.DataBind();
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        LinkButton lk = (LinkButton)(e.Row.Cells[5].Controls[0]);
        e.Row.Attributes["Onclick"] = ClientScript.GetPostBackClientHyperlink(lk, "");
    }
}

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    TextBox1.Text = GridView1.SelectedRow.Cells[0].Text;
    TextBox2.Text = GridView1.SelectedRow.Cells[1].Text;
    TextBox3.Text = GridView1.SelectedRow.Cells[2].Text;
    TextBox4.Text = GridView1.SelectedRow.Cells[3].Text;
    TextBox5.Text = GridView1.SelectedRow.Cells[4].Text;
}

then in the default.aspx page, set EnableEventValidation

<%@ Page Language="VB" EnableEventValidation="false" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
