问题描述
我将行添加到GridView中. GridView中有20列.我如何在GridView中执行类似Colspan的功能，该功能可以在2-3列以下显示2-3行，并保留为Colspan.
基本上，我希望在GridView的行中实现GridView中的Colspan.
因此，我现在的GV就像;
Col 1 Col 2 Col 3 Col 4 ...... Col 20
Cell1 Cell2 Cell3 Cell 3 Cell 4 ...... Cell 20(对于行#1)
我希望有
之类的东西Col 1 Col 2 Col 3 Col 4 ...... Col 20
Cell1 Cell2 ...... Cell 20 (For Rows # 1)
让我知道任何查询.
谢谢

您需要处理GridView的OnrowCreated事件，如下所示:
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);
}
}
您的标记应该是这样的:
<asp:GridView runat="server" ID="grid" OnRowCreated="grid_RowCreated" >
在上面的示例中，我用以下方式填充了网格:
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:
我只是意识到您想拥有一行(不一定是标题)，以便您可以做:
: 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);
}
}
它将产生:

BoundField和TemplateField标签具有属性ItemStyle-Width =" 22％"，因为您可以看到，可以为每列设置它，并以百分比响应
问题描述
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.
Basically i wish to implement colspan in gridview on the rows of the gridview.
hence my present gv is like ;
Col 1 Col 2 Col 3 Col 4 ...... Col 20
Cell1 Cell2 Cell3 Cell 4 ...... Cell 20 (For Rows # 1)
I wish to have something like
Col 1 Col 2 Col 3 Col 4 ...... Col 20
Cell1 Cell2 ...... Cell 20 (For Rows # 1)
Let me know for any query.
Thanks

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);
}
}
Your markup should be something like this:
<asp:GridView runat="server" ID="grid" OnRowCreated="grid_RowCreated" >
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();
And it produces this:
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);
}
}
And it will produce:

BoundField and TemplateField tags has the property ItemStyle-Width="22%" as you can see you can set it for each column with a percentage to be responsive
