GridView模板列编辑

    绑定模板列,<ItemTemplate><Label /></ItemTemplate> LinkUrl(连接字符串),若字符串过长,则截取(Substring(0,50))前50个字符,后面的用"..."代替,但数遍移动到该字符串上面,提示(Toollip)字符串全文。
    编辑模板列,需要添加<EditItemTemplate>
  <EditItemTemplate>
       <asp:TextBox ID="txtLink" runat="server" Text='<%# Eval("LinkUrl") %>' Width="320px">
        </asp:TextBox>
   </EditItemTemplate>
<asp:TemplateField>
     <ItemTemplate>
          <asp:Label ID="Label1" runat="server" Text='<%# Eval("LinkUrl").ToString().Length > 50? Eval("LinkUrl").ToString().Substring(0,50)+"...":Eval("LinkUrl") %>'
 ToolTip='<%# Eval("LinkUrl") %>'>
          </asp:Label>
     </ItemTemplate>
      <EditItemTemplate>
            <asp:TextBox ID="txtLink" runat="server" Text='<%# Eval("LinkUrl") %>' Width="320px">
           </asp:TextBox>
      </EditItemTemplate>
       <HeaderTemplate>
             <asp:Literal ID="Literal2" runat="server" Text="Link Url"></asp:Literal>
       </HeaderTemplate>
        <ItemStyle HorizontalAlign="Left" Width="320px" />
</asp:TemplateField>

截取字符串: <Label ID="lblLink" runat="server' Text='<%# Eval("LinkUrl").ToString().Length > 50? Eval("LinkUrl").ToString().Substring(0,50)+"...":Eval("LinkUrl") %>' ToolTip='<%# Eval("LinkUrl") %>' > 

编辑,后台代码:

string linkUrl = (((TextBox)grdType.Rows[e.RowIndex].Cells[2].FindControl("txtLink")).Text).ToString().Trim();

protected void grdType_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string linkID = grdType.DataKeys[e.RowIndex].Value.ToString();
string linkText = (((TextBox)grdType.Rows[e.RowIndex].Cells[1].Controls[0]).Text).ToString().Trim();
string linkUrl = (((TextBox)grdType.Rows[e.RowIndex].Cells[2].FindControl("txtLink")).Text).ToString().Trim();

LinkBLL platBLL = new LinkBLL();//MVC架构,编辑Link部分
int i = platBLL.UpdateLink(linkText, linkUrl, Int32.Parse(linkID));
if (i > 0)
{
ClientScript.RegisterStartupScript(this.GetType(), "", "alert('Update Link sucessfully!')", true);//提示编辑成功
}
grdType.EditIndex = -1;//释放当前所编辑的行
BindLink();//重新绑定GridView
}
