如何使用asp.net在可编辑网格视图的每个单元格中添加更多控件
我在我的网络应用程序中使用网格视图控件.. 我的网格视图看起来像这样。
单击“添加”按钮时，我得到的结果如下所示。
但是我的预期结果就是这个......我的错误在哪里？我该怎么办？
这是我的编码..

2 个答案:
答案 0 :(得分：2)
请进行以下更改....
1）在代码行下面的addnewrow（）函数更改：
dtCurrentTable.Rows[i - 1]["Item Description"] = box3.Text;
dtCurrentTable.Rows[i - 1]["Item Description"] = box4.Text;
dtCurrentTable.Rows[i - 1]["Item Description"] = box5.Text;
dtCurrentTable.Rows[i - 1]["Item Description"] = box6.Text;
更改代码如下：
dtCurrentTable.Rows[i - 1]["Item Description"] = box3.Text + "," + box4.Text + "," + box5.Text + "," + box6.Text;
同样的逻辑适用于订单数量，UOM，费率，货币和金额字段/控件的商店值
2）在SetPreviousData（）函数中更改代码行下方：
box3.Text = dt.Rows[i]["Item Description"].ToString();
更改代码如下：
if(Convert.ToString(dt.Rows[i]["Item Description"]).Trim() != "")
{
string[] strDesc = Convert.ToString(dt.Rows[i]["Item Description"]).Trim().Split(',');
box3.Text = strDesc[0].ToString();
box4.Text = strDesc[1].ToString();
box5.Text = strDesc[2].ToString();
box6.Text = strDesc[3].ToString();
}
同样的逻辑适用于订单数量，UOM，费率，货币和金额字段/控件的商店值

在addnewrow（）函数中替换下面的代码：
for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
{
DropDownList box2 = (DropDownList)GridView1.Rows[0].Cells[1].FindControl("DropDownList1");
box2.DataSource = SIMBL.ShowSalesOrderArticleNumberInfo();
box2.DataTextField = "Port_Number";
box2.DataValueField = "Description";
box2.DataBind();
box2.Items.Insert(0, " ");
}
将以上代码替换为以下代码行...
for (int i = 0; i <= dtCurrentTable.Rows.Count; i++)
{
DropDownList box2 = (DropDownList)GridView1.Rows[i].Cells[1].FindControl("DropDownList1");
box2.DataSource = SIMBL.ShowSalesOrderArticleNumberInfo();
box2.DataTextField = "Port_Number";
box2.DataValueField = "Description";
box2.DataBind();
box2.Items.Insert(0, " ");
DropDownList box12 = (DropDownList)GridView1.Rows[i].Cells[4].FindControl("DropDownList3");
box12.DataSource = SIMBL.ShowUnitItemInfo();
box12.DataTextField = "Name";
box12.DataValueField = "Symbol";
box12.DataBind();
box12.Items.Insert(0, " ");
DropDownList box13 = (DropDownList)GridView1.Rows[i].Cells[4].FindControl("DropDownList4");
box13.DataSource = SIMBL.ShowUnitItemInfo();
box13.DataTextField = "Name";
box13.DataValueField = "Symbol";
box13.DataBind();
box13.Items.Insert(0, " ");
DropDownList box14 = (DropDownList)GridView1.Rows[i].Cells[4].FindControl("DropDownList5");
box14.DataSource = SIMBL.ShowUnitItemInfo();
box14.DataTextField = "Name";
box14.DataValueField = "Symbol";
box14.DataBind();
box14.Items.Insert(0, " ");
}
