這是我的.cs
代碼:如何使用rowdeleting事件刪除gridview中的行?
protected void Gridview1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Gridview1.DeleteRow(e.RowIndex);
Gridview1.DataBind();
}
,這是markup
,
<asp:gridview ID="Gridview1" runat="server" ShowFooter="true"
AutoGenerateColumns="false" OnRowDeleting="Gridview1_RowDeleting">
<Columns>
<asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
<asp:TemplateField HeaderText="Column Name">
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<%-- <asp:TemplateField HeaderText="Header 2">
<ItemTemplate>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>--%>
<asp:TemplateField HeaderText="Data Type">
<ItemTemplate>
<asp:DropDownList ID="ddldatatype" runat="server">
<asp:ListItem>varchar</asp:ListItem>
<asp:ListItem>int</asp:ListItem>
<asp:ListItem>numeric</asp:ListItem>
<asp:ListItem>uniqueidentifier</asp:ListItem>
<asp:ListItem>char</asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
<FooterStyle HorizontalAlign="Right" />
<FooterTemplate>
<asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" OnClick="ButtonAdd_Click"/>
<asp:Button ID="ButtonDel" runat="server" Text="Delete Row" OnClick="ButtonDel_Click" />
<input type="hidden" runat="server" value="0" id="hiddencount" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkdelete" runat="server" CommandName="Delete" >Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:gridview>
請sugegest我。我做了這麼多..但仍然沒有刪除的行...
protected void Gridview1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
//Gridview1.DeleteRow((int)Gridview1.DataKeys[e.RowIndex].Value);
//Gridview1.DeleteRow(e.RowIndex);
//Gridview1.DataBind();
foreach(DataRow dr in dt.Rows)
{
dt.Rows.Remove(dr);
dt.Rows[e.RowIndex].Delete();
}
Gridview1.DeleteRow(e.RowIndex);
// dt = (DataTable)Gridview1.DataSource;
Gridview1.DataSource = dt;
Gridview1.DataBind();
}
請提出一個問題 –
