用一列插入一行datagridview c＃ [英] insert a row with one column datagridview c#

问题描述

我想在c＃.net winform中的datagridview中插入一行，它有一个单元格（意思是合并单元格）。我使用这行作为后续行的标题。有没有解决方案来解决这个需要？

tnx

解决方案

我不知道你想做什么，你能提供一些更多的细节，你正在尝试完成什么，还有一些数据样本？你定位什么版本的.net？

这里有一点代码将两列组合成一列，不知道这是你以后的。 / p>

*。aspx

 < asp：GridView ID =GridView1 AutoGenerateColumns =falserunat =server> 
<列> 
< asp：TemplateField HeaderText =CombinedHeader> 
< ItemTemplate> 
< asp：Label ID =lblBreakDownrunat =serverText ='<％＃string.Format（{0}（{1}），Eval（Column1），Eval Column2））％>'>< / asp：Label> 
< / ItemTemplate> 
< / asp：TemplateField> 
< / Columns> 
< / asp：GridView> 
  

.aspx.cs

  protected void Page_Load（object sender，EventArgs e）
 {
 DataTable dtTemp = new DataTable（）; 
 dtTemp.Columns.Add（Column1，typeof（System.String））; 
 dtTemp.Columns.Add（Column2，typeof（System.String））; 
 
 DataRow drRow1 = dtTemp.NewRow（）; 
 drRow1 [0] =Data1; 
 drRow1 [1] =Data2; 
 
 dtTemp.Rows.Add（drRow1）; 
 GridView1.DataSource = dtTemp; 
 GridView1.DataBind（）; 
} 
  

i want to insert a row to a datagridview in c#.net winform, that have one cell (it means merging cells). i use this row as title of later rows. is there any solution to answer this need?

tnx

解决方案

I'm not sure what you are trying to do, can you provide a little more detail on what you are trying to accomplish, and with some data samples? what version of .net are you targeting?

here is a little bit of code that combines two columns into one column, not sure if this is what you are after.

*.aspx

<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server">
    <Columns>
        <asp:TemplateField HeaderText="CombinedHeader">
            <ItemTemplate>
                <asp:Label ID="lblBreakDown" runat="server" Text='<%#  string.Format("{0} ({1})",Eval("Column1"),Eval("Column2") ) %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

.aspx.cs

    protected void Page_Load(object sender, EventArgs e)
    {
        DataTable dtTemp = new DataTable();
        dtTemp.Columns.Add("Column1", typeof(System.String));
        dtTemp.Columns.Add("Column2", typeof(System.String));

        DataRow drRow1 = dtTemp.NewRow();
        drRow1[0] = "Data1";
        drRow1[1] = "Data2";

        dtTemp.Rows.Add(drRow1);
        GridView1.DataSource = dtTemp;
        GridView1.DataBind();
    }
