想要在单击命令drop时从gridview中删除行 [英] Want do delete row from gridview when command drop is clicked

问题描述

当您点击gridview中的drop（命令字段）时，某些行会被删除，而其他行则不会删除



相同的问题将应用于注释行当我也尝试它们时



我尝试过：



HTML

Some of the rows delete while others don't when you click on the drop (commandfield) in the gridview

The same issue is applied to the commented lines when I try them too

What I have tried:

The HTML

<asp:GridView ID="Grid" runat="server" AutoGenerateColumns="False" Height="65px" OnSelectedIndexChanged="Grid_SelectedIndexChanged" BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1" GridLines="None" OnRowDeleting="Grid_RowDeleting">
            <Columns>
                <asp:BoundField HeaderText="id" DataField="id" />
                <asp:BoundField HeaderText="firstname" DataField="firstname" />
                <asp:BoundField HeaderText="lastname" DataField="lastname" />
                <asp:BoundField HeaderText="age" DataField="age" />
                <asp:CommandField DeleteText="Drop" ShowDeleteButton="True" />
            </Columns>

            <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />
            <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" />
            <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" />
            <RowStyle BackColor="#DEDFDE" ForeColor="Black" />
            <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />
            <SortedAscendingCellStyle BackColor="#F1F1F1" />
            <SortedAscendingHeaderStyle BackColor="#594B9C" />
            <SortedDescendingCellStyle BackColor="#CAC9C9" />
            <SortedDescendingHeaderStyle BackColor="#33276A" />

        </asp:GridView>

C＃

The C#

protected void Grid_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            DataTable dtDatas = (DataTable)ViewState["dtDatas"];
            if (dtDatas.Rows.Count > 0)
            {
                //Grid.DeleteRow(Grid.SelectedIndex);
                //dtDatas.Rows.RemoveAt(0);
                dtDatas.Rows[e.RowIndex].Delete();
                Grid.DataSource = dtDatas;
                Grid.DataBind();
                
            }
        }

推荐答案

您是否在调试模式下检查了e的值。 RowIndex是要确保它要删除的行吗？



另外，我假设你在初始化时用另一种方法将DataTable绑定到GridView，并且所以不需要在delete方法中再次完成。

Have you checked in debug mode what the value of e.RowIndex is to make sure its the row you want to delete?

Also, I assume you're binding the DataTable to the GridView in another method when its initialized, and so it doesn't need to be done again in the delete method.
