如何获取DataGrid中控件的ID?
DataGrid:
<asp:datagrid id= "MyDataGrid " runat= "server " CssClass= "td " BorderColor= "#C0FFFF " DataKeyField= "BookId "AllowSorting= "True " AutoGenerateColumns= "False " AllowPaging= "True " Width= "100% ">
<HeaderStyle CssClass= "tttable " BackColor= "#FFFFC0 "> </HeaderStyle>
<Columns>
<asp:HyperLinkColumn Text= "Name " DataNavigateUrlField= "BookId " DataNavigateUrlFormatString= "ShowBook.aspx?bookid={0} "
DataTextField= "Name " SortExpression= "Name " HeaderText= "Book Name " NavigateUrl= "BookId "> </asp:HyperLinkColumn>
<asp:BoundColumn DataField= "Publisher " SortExpression= "Publisher " HeaderText= "Publisher "> </asp:BoundColumn> <asp:BoundColumn DataField= "Author " SortExpression= "Author " HeaderText= "Author "> </asp:BoundColumn>
<asp:BoundColumn DataField= "Translator " SortExpression= "Translator " HeaderText= "Translator "> </asp:BoundColumn>
<asp:BoundColumn DataField= "Price " SortExpression= "Price " HeaderText= "Price "> </asp:BoundColumn>
<asp:ButtonColumn Text= "<img src=img/basket.gif border=0 alt=Delete /> " HeaderText= "Cart " CommandName= "Cart ">
<ItemStyle HorizontalAlign= "Center "> </ItemStyle>
</asp:ButtonColumn>
<asp:TemplateColumn HeaderText= "Delete ">
<ItemStyle HorizontalAlign= "Center "> </ItemStyle>
<ItemTemplate>
<asp:ImageButton id= "del " runat= "server " CausesValidation= "false " CommandName= "Delete " ImageUrl= "img\delete.gif "> </asp:ImageButton>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
<PagerStyle Mode= "NumericPages "> </PagerStyle>
</asp:datagrid>
我想给ImageButton加一个确认,
private void MyDataGrid_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
ImageButton lkBtn = (ImageButton)e.Item.Cells[6].FindControl( "del ");
lkBtn.Attributes.Add( "onClick ", "return confirm( '你能确定要删除此书籍类型吗 '); " <--未将对象引用设置到对象的实例。);
}
[解决办法]
直接在 <asp:ImageButton id= "del " runat= "server " CausesValidation= "false " CommandName= "Delete " ImageUrl= "img\delete.gif "> </asp:ImageButton> 中加上onClientClick不就可以了，
要不就(ImageButton)e.Item.FindControl( "del ");试试
[解决办法]
在窗体初始化的InitializeComponent()中添加如下语句即可：
this.MyDataGrid.DeleteCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.MyDataGrid_DeleteCommand);
[解决办法]
还有记得把你的删除动作写在
MyDataGrid_DeleteCommand()
{ }
事件中。
------解决方案--------------------
我想给ImageButton加一个确认,
private void MyDataGrid_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
ImageButton lkBtn = (ImageButton)e.Item.Cells[6].FindControl( "del ");
lkBtn.Attributes.Add( "onClick ", "return confirm( '你能确定要删除此书籍类型吗 '); " <--未将对象引用设置到对象的实例。);
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
找到该控件:
ImageButton lkBtn = (ImageButton)e.ItemFindControl( "del ");
事件可在: ItemDataBound, ItemCreate 设置
