    Gridview Column Width

    I have a Gridview binding to a DataTable source. I'd like to set the
    column with of the second column. I cannot do this apparently because
    when AutoGenerateCol umns=true, they do not appear in the columns
    collection.

    I modified the RowCreated even to gridview, and I can change
    properties on the cells, but not width. (setting tooltip, background
    color, etc, all work but changing width has no effect). Here's
    sample code I am using:

    //Inside RowCreated Gridview Even
    if (e.Row.RowType == DataControlRowT ype.DataRow)
    {
    foreach (TableCell tCell in e.Row.Cells)
    {
    tCell.ControlSt yle.Width = 600; //no effect
    tCell.Width = 600; //no effect
    }
    }

    So the main question is, "Any way possible to change Gridview Column
    Width with a DataTable source and AutoGenerateCol umns=true?" Please
    Help, I am at a loss here and been working on this for days....

    PS
    little more background- I have a dynamic DataTable (could be 1 to
    over 3000 columns), so I must have AutoGenerateCol umns=true (I can't
    set it to false, and create a boundfield for an unknown dynamic sized
    table).

      you're kidding, right? up to 3000 columns? .... this is software ... to be
      used by humans ... not alchemy

      leaving that aside (which you should not) it doesn't seem advisable to alter
      column width every time a row is created; have you considered all the work
      for the processor you're creating here .... I hate to ask how many rows
      there may be in the control ...

          nope, it's a timespread and not really processor intensive. but still
          the question remains, why in the world
          can I not change a column width to a DataTable source with
          AutoGenerateCol umns=true?
          Woudln't this be something a lot of people would want to do?

          I can't imagine the only answer is to turn AutoGenerateCol umns=false,
          and add a bound field, map this
          to the datatable, etc. Please, anyone out there know the answer?
          Thanks!

              Re: Gridview Column Width

              i was able to make a workaround by adding a bunch of spaces to the
              header row column but
              still unable to get the .Width property to explicitly change the
              column width on header row or
              datarows.

              here's sample code:

              if (e.Row.RowType == DataControlRowT ype.Header)
              {
              if (e.Row.Cells[1].Text == "Column Header Text")
              {
              e.Row.Cells[1].Wrap = false;
              e.Row.Cells[1].Width = Unit.Percentage (1000);
              e.Row.Cells[1].Text = "Column Header Text " +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
              "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp";
              }

                  well ... I fooled around with this and I can get .Width property to
                  "influence" the width of the cell; if I set it to 5, it'll make it as small
                  as possible, and if I set it to 2000, it'll make it as wide as possible ...
                  but it will not just use the metric supplied absolutely

                  but here's the thing: if you look at the HTML source you should see:

                  <td style="width:20 00px;">

                  if you set your Width to 2000, for example; so the code does what you ask
                  it to but the browser (IE6 in this case) just renders it as it "wants to"
                  .....


                  here's sample code:
                  >
                  if (e.Row.RowType == DataControlRowT ype.Header)
                  {
                  if (e.Row.Cells[1].Text == "Column Header Text")
                  {
                  e.Row.Cells[1].Wrap = false;
                  e.Row.Cells[1].Width = Unit.Percentage (1000);
                  e.Row.Cells[1].Text = "Column Header Text " +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp" +
                  "&nbsp&nbsp&nbs p&nbsp&nbsp&nbs p&nbsp&nbsp";
                  }
