问题描述

需要帮助来解决的GridView布局相关的一个问题。我想使用C＃.NET语言来实现与ItemTemplate中列custome的GridView，并想用ROWSPAN属性包括视图。

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.

我试着用下面code，但对我的

I tried to use below code but didn't work for me Here

请检查code这是我使用的：

Please check the code which i used:

 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;
            }
        }
    }

}

可是每次 gvRow.Cells [cellCount]。文本== GV previousRow.Cells [cellCount]。文本是空白的。

因此，网格正在怪异形状。不知道这里发生了什么。

Hence the grid is taking weird shapes. Don't know what is happening here.

谁能帮助？

推荐答案

使用RowDataBound事件来代替：

Use RowDataBound event instead:

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;
        }
    }
}
