[英]How to create a dynamic gridview?
您可以通過編程在GridView中使用RowSpan和ColSpan。 您將必須使用GridView的OnRowDataBound
事件。
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
//chech if the row is the header
if (e.Row.RowType == DataControlRowType.Header)
{
//span 3 columns, starting with the first one (0)
e.Row.Cells[0].ColumnSpan = 3;
//remove the other 2 column cells
e.Row.Cells.RemoveAt(2);
e.Row.Cells.RemoveAt(1);
}
//check if the row is a datarow
else if (e.Row.RowType == DataControlRowType.DataRow)
{
//the last rownumber of the rows to be spanned, can only count backwards because next row does not exist yet.
if (e.Row.RowIndex == 8)
{
//amount of rows to be spanned
int rowSpanCount = 4;
//find the first cell counting backwards (8 - rowSpanCount)
GridViewRow firstRow = GridView1.Rows[e.Row.RowIndex - rowSpanCount];
firstRow.Cells[1].RowSpan = rowSpanCount;
//hide the other cells that are part of the rowspan
for (int i = 1; i < rowSpanCount; i++)
{
GridViewRow nextRow = GridView1.Rows[e.Row.RowIndex - i];
nextRow.Cells[1].Visible = false;
}
}
}
}
在我的代碼段中,HeaderRow將跨越所有3列,而單元格4則將第1列跨越4行。
