Question

我有一个gridview，我正在尝试将数据提取到填充3个文本框...我尝试了很多方法，但我无法以正确的方式做到这一点......我我手动构建了gridview，因此没有“editTemplate”......有人可以用正确的方式指导我这样做吗？这就是我的gridview的样子：

    <asp:GridView ID="GridView1" runat="server"  AllowPaging="True" 
                                EmptyDataText="No parts has been added to the model, please add a part."
                                BorderColor="Black" BorderStyle="Solid"  BorderWidth="2px" 
                                CellPadding="3" onrowcommand="GridView1_RowCommand">
                                <Columns>
                                <asp:TemplateField HeaderText="">
                                 <ItemTemplate>
                                   <asp:LinkButton ID="EditButton" runat="server" CssClass="EditButton" CommandName="Edit" Text="Edit" />
                                 </ItemTemplate>
                                 </asp:TemplateField>
                                 <asp:TemplateField HeaderText="">
                                 <ItemTemplate>
                                   <asp:LinkButton ID="DeleteButton" runat="server" CssClass="DeleteButton" CommandName="Delete" Text="Delete" />
                                 </ItemTemplate>
                                 </asp:TemplateField>
                                </Columns>
                            <HeaderStyle BackColor="#FFFFCC"  BorderColor="Black" BorderStyle="Solid" 
                                BorderWidth="2px" />
                        </asp:GridView>

然后，这就是我为该gridview添加必要的列的方式：

     protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        dt = new DataTable();
        MakeDataTable();
        EmptyDataString();
    }
    else
    {
        dt = (DataTable)ViewState["DataTable"];
    }
    ViewState["DataTable"] = dt; 

}

#region GridView

private void EmptyDataString()
{
    TemplateBuilder tmpEmptyDataTemplate = new TemplateBuilder();
    tmpEmptyDataTemplate.AppendLiteralString("No parts has been added to the model, please add a part.");
    GridView1.EmptyDataTemplate = tmpEmptyDataTemplate;
    GridView1.DataBind();
}

private void MakeDataTable()
{
    dt.Columns.Add("Item");
    dt.Columns.Add("Quantity");
    dt.Columns.Add("Price P/Quantity");
}

private void AddToDataTable()
{
    DataRow dr = dt.NewRow();
    dr["Item"] = txtPart.Text;
    dr["Quantity"] = numQuantity.Text;
    dr["Price P/Quantity"] = txtPricePQ.Text;
    dt.Rows.Add(dr);
}

private void BindGrid()
{
    GridView1.DataSource = dt;
    GridView1.DataBind();
}

protected void btnAddPart_Click(object sender, EventArgs e)
{
    AddToDataTable();
    BindGrid();
    ClearNewParts();
}
#endregion

这些是我试图做到这一点的一些方法:(所有这些都被注释掉了，因为我转向下一步做这个......

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
  //  int index = Convert.ToInt32(e.CommandArgument);
    if (e.CommandName == "Edit")
    {
        if (GridView1.SelectedRow != null)
        {
            //dataTable.Rows[GridView1.SelectedRow].BeginEdit();
            //dataTable.Rows[GridView1.SelectedRow]["yourFieldName"] = newValue;
            //dataTable.Rows[GridView1.SelectedRow].EndEdit();
            //gridView.DataSource = dataTable;
        }
      //  GridViewRow row = GridView1.Rows[e.RowIndex];

       // Department = ((GridViewRow(((LinkButton)e.CommandSource).NamingContainer)).Cells[2].Text;
      //  txtPart.Text = GridView1.SelectedRow.Cells[1].Text;
       // txtPart.Text = GridView1.Rows[index].Cells[2].Text;
       // Response.Write(gv.Rows[index].Cells[0].Text); //consider you use bound field and the column you want to show its value is the first column.
    }

我知道我在如何尝试从gridview中提取数据以填充文本框，但不确定如何......我做错了什么....（我仍然是初级编程，基本上是第一次做我想在这里实现的目标）....

Answer 1

使用以下代码＆gt;＆gt;

如果是Windows应用＆gt;＆gt;

for(int i=0;i<gv.Rows.Count;i++)
{
       id=gv.selectedRows[i].cells[0][0].value.toString();
       name=gv.selectedRows[i].cells[0][0].value.toString();
}

否则

您可以从gridview获取选定的行。

如果你想要没有选择，那么，

for(int i=0;i<gv.Rows.Count;i++)
    {
           id=gv.Rows[i].cells[0][0].value.toString();
           name=gv.Rows[i].cells[0][0].value.toString();
    }

第三种选择＆gt;＆gt;

     if (e.CommandName == "Edit")
        {
            if (GridView1.SelectedRow != null)
            {
                //dataTable.Rows[GridView1.SelectedRow].BeginEdit();
                //dataTable.Rows[GridView1.SelectedRow]["yourFieldName"] = newValue;
                //dataTable.Rows[GridView1.SelectedRow].EndEdit();
                //gridView.DataSource = dataTable;
            }
          //  GridViewRow row = GridView1.Rows[e.RowIndex];
    for(int i=0;i<GridView1.Rows.Count;i++)
{
            Department = ((GridViewRow(((LinkButton)e.CommandSource).NamingContainer)).Cells[2].Text;
            txtPart.Text = GridView1.SelectedRow[i][0].Cells[1].Text;
           txtPart.Text = GridView1.Rows[i][0].Cells[2].Text;
           Response.Write(gv.Rows[i][0].Cells[0].Text); //consider you use bound field and the column you want to show its value is the first column.
        }
}

此外，您可以将这些变量设置为文本框。

或直接也可以设置它。

尝试。
