Question

下面是我的输出，我试图合并标头和子标头。但是这对我来说不起作用，因为前三列正在重新创建，我希望标题脚本高于fromdate，todate，分析师

上面提到的是设计器代码，请找到创建行标题的代码

protected void grv_taskfilter_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header) // If header created
    {
        GridView Projectgrid = (GridView)sender;

        // Creating a Row
        GridViewRow HeaderRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);


        TableCell HeaderCell = new TableCell();
        HeaderCell.Text = "ProjectName";
        HeaderCell.HorizontalAlign = HorizontalAlign.Center;
        HeaderCell.RowSpan = 2;
        HeaderCell.ColumnSpan = 1;
        HeaderCell.CssClass = "HeaderStyle";
        HeaderRow.Cells.Add(HeaderCell);


        HeaderCell = new TableCell();
        HeaderCell.Text = "Project nos";
        HeaderCell.HorizontalAlign = HorizontalAlign.Center;
        HeaderCell.RowSpan = 2;
        HeaderCell.ColumnSpan = 1;
        HeaderCell.CssClass = "HeaderStyle";
        HeaderRow.Cells.Add(HeaderCell);


        HeaderCell = new TableCell();
        HeaderCell.Text = "Questionnaire Submission for sripting";
        HeaderCell.HorizontalAlign = HorizontalAlign.Center;
        HeaderCell.RowSpan = 2;
        HeaderCell.ColumnSpan = 1;
        HeaderCell.CssClass = "HeaderStyle";
        HeaderRow.Cells.Add(HeaderCell);


        HeaderCell = new TableCell();
        HeaderCell.Text = "Scripting";
        HeaderCell.HorizontalAlign = HorizontalAlign.Center;
        HeaderCell.ColumnSpan = 3; 
        HeaderCell.CssClass = "HeaderStyle";
        HeaderRow.Cells.Add(HeaderCell);

        //Adding the Row at the 0th position (first row) in the Grid
        Projectgrid.Controls[0].Controls.AddAt(0, HeaderRow);
    }
}

Answer 1

根据您的要求，您需要标题脚本来自日期，todate，分析师

这些列

所以你可以通过将col col 6给头标题Scripting

来做到这一点

HeaderCell = new TableCell();
HeaderCell.Text = "Scripting";
HeaderCell.HorizontalAlign = HorizontalAlign.Center;
HeaderCell.ColumnSpan = 6; // Give Colspan 6 to header
HeaderCell.CssClass = "HeaderStyle";
HeaderRow.Cells.Add(HeaderCell);

Answer 2

但是这对我来说不起作用，因为前三列正在增加重新创建

因为你告诉它这样做。在网格视图中创建多行时，你所做的实际上是黑帮IMO的“一部分”。要完成解决方案，您需要隐藏您创建的三个额外标题。为此，您需要将gridview绑定到RowDataBound事件，如下所示：

protected void grv_taskfilter_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        e.Row.Cells[0].Visible = false; 
        e.Row.Cells[1].Visible = false; 
        e.Row.Cells[2].Visible = false;  
    }
}

在gridview中创建标题和子标题
