How to Set a gridview column width when binding to a datatable

I am binding a table to a gridview in asp.net as such

grdIssues.DataSource = mdtIssues;

grdIssues.DataB开发者_开发技巧ind();

The problem is I cannot then control the column width, asp.net seems to decided on it's own what width each column should be. Methods such as

 grdIssues.Columns[0].ItemStyle.Width = 100;
 grdIssues.Columns[1].ItemStyle.Width = 100;

don't work because the columns are created dynamically. I cannot believe there isn't a way to do this short of manually creating each column and filling each row.

You dont have to manually create the columns to set them the width, you can do this

 foreach (DataControlField column in OrdersGV.Columns)
    {
      column.ItemStyle.Width = Unit.Pixel(100);
    }

I was able to change the width of a certain Gridview column (bound to a Datatable) with the RowDataBound event:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) {
    e.Row.Cells[0].Attributes["width"] = "200px";
}

I like to answer my own question whenever I can so future users searching the thread will find the answer.

I could not find a way to do what I wanted directly. However I found if I define the columns myself, I could change the properties. In this example, I wanted to center the column data. Something like this.

BoundField bdfRaisedDate = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfRaisedDate, "RaisedDateShort",    "Opened", "RaisedDate");

grdIssues.Columns.Add(bdfRaisedDate);

grdIssues.DataSource = mdtIssues;

grdIssues.DataBind();

public static void SetBoundFieldCenter(ref BoundField bdfAny, string pDataField, string pHeadingValue, string  pSortExpression)
{
      bdfAny.DataField = pDataField;
      bdfAny.HeaderText = pHeadingValue;
      bdfAny.SortExpression = pSortExpression;
      bdfAny.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;
      bdfAny.ItemStyle.HorizontalAlign = HorizontalAlign.Center;
}

I did it as:

gridView1.HeaderRow.Cells[0].Attributes["Width"] = "100px";
gridView1.HeaderRow.Cells[1].Attributes["Width"] = "50px";
gridView1.HeaderRow.Cells[2].Attributes["Width"] = "200px";

I'd do it like this:

foreach (DataControlField field in grdIssues.Columns)
{
  field.HeaderStyle.Width = 100;
}
