How to use Rowspan in Gridview for 1st Column only
提问by Pratik
Need help to resolve a issue related with Gridview layout. I am trying to implement custome Gridview with Itemtemplate Columns using C#.Net language and want to include view using RowSpan property.
需要帮助解决与 Gridview 布局相关的问题。我正在尝试使用 C#.Net 语言使用 Itemtemplate Columns 实现自定义 Gridview，并希望使用 RowSpan 属性包含视图。
I tried to use below code but didn't work for me Here
我尝试使用下面的代码，但对我不起作用这里
Please check the code which i used:
请检查我使用的代码：
protected void GridView31_DataBound1(object sender, EventArgs e)
{
for (int rowIndex = grdView31.Rows.Count - 2; rowIndex >= 0; rowIndex--)
{
GridViewRow gvRow = grdView31.Rows[rowIndex];
GridViewRow gvPreviousRow = grdView31.Rows[rowIndex + 1];
for (int cellCount = 0; cellCount < gvRow.Cells.Count; cellCount++)
{
if (gvRow.Cells[cellCount].Text == gvPreviousRow.Cells[cellCount].Text)
{
if (gvPreviousRow.Cells[cellCount].RowSpan < 2)
{
gvRow.Cells[cellCount].RowSpan = 2;
}
else
{
gvRow.Cells[cellCount].RowSpan =
gvPreviousRow.Cells[cellCount].RowSpan + 1;
}
gvPreviousRow.Cells[cellCount].Visible = false;
}
}
}
}
But every time the gvRow.Cells[cellCount].Text == gvPreviousRow.Cells[cellCount].Textis blank.
但每次gvRow.Cells[cellCount].Text == gvPreviousRow.Cells[cellCount].Text都是空白。
Hence the grid is taking weird shapes. Don't know what is happening here.
因此，网格呈现出奇怪的形状。不知道这里发生了什么。
Can anyone help?
任何人都可以帮忙吗？

Use RowDataBound event instead:
改用 RowDataBound 事件：
void GridView31_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow )
{
if (e.Row.RowIndex % 4 == 0)
{
e.Row.Cells[0].Attributes.Add("rowspan", "4");
}
else
{
e.Row.Cells[0].Visible = false;
}
}
}

{
GridViewRow gvRow = grdView31.Rows[rowIndex];
GridViewRow gvPreviousRow = grdView31.Rows[rowIndex + 1];
if (i % 4 !=0)
{
if (gvPreviousRow.Cells[0].RowSpan < 2)
{
gvRow.Cells[0].RowSpan = 2;
}
else
{
gvRow.Cells[0].RowSpan = gvPreviousRow.Cells[0].RowSpan + 1;
}
gvPreviousRow.Cells[0].Visible = false;
}
i++;
}
This worked our for me. Trial & error :)
这对我有用。试错:)

'VB.NET Code
Private Sub DG_Data_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles DG_Data.RowDataBound
Try
'fusion , rowspan , colspan ,
If e.Row.RowType = DataControlRowType.DataRow Then
If e.Row.RowIndex Mod 4 = 0 Then
e.Row.Cells(0).Attributes.Add("rowspan", "4")
Else
e.Row.Cells(0).Visible = False
End If
End If
Catch ex As Exception
jq.msgErrorLog(ex)
End Try
End Sub
