如何在绑定到数据表时设置gridview列宽

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

我正在将表绑定到asp.net中的gridview

grdIssues.DataSource = mdtIssues;

grdIssues.DataBind();

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

问题是我无法控制列宽,asp.net似乎决定了它自己的每列应该是什么宽度。方法如

 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.

不起作用,因为列是动态创建的。我无法相信没有办法在手动创建每个列并填充每一行时做到这一点。

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

您不必手动创建列来设置宽度,您可以这样做

 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:

我能够使用RowDataBound事件更改某个Gridview列的宽度(绑定到Datatable):

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

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.

我找不到直接做我想要的方法。但是我发现如果我自己定义列,我可以更改属性。在这个例子中,我想使列数据居中。像这样的东西。

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:

我做到了:

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:

我这样做:

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