colspan gridview 行 [英] colspan gridview rows

问题描述

我已将行添加到 gridview.gridview 中有 20 列.我如何在 gridview 中执行类似 colspan 的功能，它可以在 2-3 列下显示 2-3 行并保留为 colspan.

I have added rows into gridview. There are 20 columns in gridview. How can i do a colspan-like feature in gridview which could show me 2-3 rows under 2-3 columns and remaining as a colspan.

基本上我希望在 gridview 的行上的 gridview 中实现 colspan.

Basically i wish to implement colspan in gridview on the rows of the gridview.

因此我现在的 gv 就像 ;

hence my present gv is like ;

Col 1 Col 2 Col 3 Col 4 ...... Col 20

Col 1 Col 2 Col 3 Col 4 ...... Col 20

Cell1 Cell2 Cell3 Cell 4 ...... Cell 20(对于第 1 行)

Cell1 Cell2 Cell3 Cell 4 ...... Cell 20 (For Rows # 1)

我希望有类似的东西

Col 1 Col 2 Col 3 Col 4 ...... Col 20

Col 1 Col 2 Col 3 Col 4 ...... Col 20

    Cell1      Cell2    ...... Cell 20   (For Rows # 1)

如有任何疑问，请告诉我.

Let me know for any query.

谢谢

推荐答案

需要对GridView的OnRowCreated事件进行如下处理:

You need to handle the OnRowCreated event of the GridView as follows:

 protected void grid_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        e.Row.Cells[2].ColumnSpan = 2;
        //now make up for the colspan from cell2
        e.Row.Cells.RemoveAt(4);
    }
}

你的标记应该是这样的:

Your markup should be something like this:

<asp:GridView runat="server" ID="grid" OnRowCreated="grid_RowCreated" >

在上面的例子中，我用这个填充了网格:

On the above example, I populated the grid with this:

DataTable dt = new DataTable();
        for (int i = 0; i < 5; i++)
        {
            dt.Columns.Add("Col " + i);
        }
        for (int i = 0; i < 10; i++)
        {
            DataRow r = dt.NewRow();
            r.ItemArray=new object[]{"row "+i,"row "+i,"row "+i,"row "+i,"row "+i};
            dt.Rows.Add(r);
        }

        grid.DataSource = dt;
        grid.DataBind();

它产生了这个:

我刚刚意识到您想让 ROWS(不一定是标题)具有特定的 colspan，在这种情况下您可以这样做:

I just realized that you wanted to have the ROWS (not necessarily the header) to have certain colspan, in which case you can do:

 protected void grid_RowCreated(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Cells[2].ColumnSpan = 2;
        //now make up for the colspan from cell2
        e.Row.Cells.RemoveAt(4);
    }
}

它会产生:
