删除网格视图中的行而不影响数据库 [英] Delete row in a gridview without affecting Database

问题描述

我试图从gridview中删除一些行而不影响数据库。所以我在代码项目本身看到的很多例子。但是下面代码的问题只是在第0个位置可以删除。但我想删除点击位置本身的行。任何人都可以提出任何建议吗？



以下是我的代码： -

Hi,
Iam trying to delete some rows from gridview without affecting the database.So many examples I saw in the code project itself.But the problem with the below code is only the row in the zeroth position can delete.But I want to delete the row in the click position itself.Can anyone suggest any idea?

Below is my code:-

protected void DeleteDemandSlabOnclick(object sender, EventArgs e)
{
    DataTable demandSlabList;
    if (txtbxTariff.Text.Contains("HT") == false)
        InitializeFixedChargeTable(out demandSlabList);
    else
        InitializeDemandChargeTable(out demandSlabList);
    foreach (GridViewRow Row in SlabsGrid.Rows)
    {
        DataRow row = demandSlabList.NewRow();
        row[0] = Row.Cells[0].Text;
        row[1] = Row.Cells[1].Text;
        row[2] = Row.Cells[2].Text;
        demandSlabList.Rows.Add(row);
    }
    if (demandSlabList.Rows.Count > 0)
    {
        demandSlabList.Rows.RemoveAt(0);
        SlabsGrid.DataSource = demandSlabList;
        SlabsGrid.DataBind();
    }
}

推荐答案

总是做坏事。

你可以找到rowindex总是在你的 GridView RowCommand 事件中。

试试这个：

Bad practice always.
You can find the rowindex always in your GridView RowCommand event.
Try this:

GridViewRow gvr = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);

int RowIndex = gvr.RowIndex; 

现在您可以使用 RemoveAt 功能删除该行。您需要传递索引作为此 RowIndex 。

Now you can delete the row using RemoveAt function. You need to pass Index as this RowIndex.
