GridView 總是顯示 Pager ( Force Pager Visible )

加入 OnPreRender 事件:

<asp:GridView ID="gv1" OnPreRender="GridView1_PreRender" runat="server">

in code-behind:

Protected Sub gv1_PreRender(ByVal sender As Object, ByVal e As EventArgs)
    Dim pagerRow As GridViewRow = GridView1.BottomPagerRow
    If pagerRow IsNot Nothing AndAlso pagerRow.Visible = False Then
         pagerRow.Visible = True
    End If
End Sub

or:

Protected Sub GridView1_PreRender(ByVal sender As Object, ByVal e As EventArgs)
    gv1.BottomPagerRow.Visible = True
End Sub

GridView 加入控制項至Pager Row ( Adding Controls To Pager Row )

在 GridView 加入 OnRowDataBound 事件:

<asp:gridview id="gv1" runat="server" autogeneratecolumns="False" onrowdatabound="gv1_RowDataBound" allowpaging="True">

in code-behind:

Protected Sub gv1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    If e.Row.RowType = DataControlRowType.Pager Then
        Dim myLabel As Label = New Label
        Dim table As Table = e.Row.Cells(0).Controls(0)
        Dim parentCell As TableCell = table.Rows(0).Cells(table.Rows(0).Cells.Count - 1)
        parentCell.Controls.Add(myLabel)
        myLabel.Text = "Some Text"
    End If
End Sub

jQuery parent() && children() ( Select input from next td )

html:

<tr>
    <td>
        <input type="text" id="txtPrev" />
    </td>
    <td>
        <input type="text" id="txtNext" />
    </td>
</tr>

找到下一個 td 裡的 input:

var flag = 0;
$("input").keypress(function(){
    var target = $(this).parent("td").next().children("input");
    if(flag%2)
        target.css("background-color", "blue");
    else
        target.css("background-color", "green");
    ++flag;
});

Demo

jQuery 關閉功能鍵 ( Disable Function Key )

function disableFKey(e){
    if( (e.which || e.keyCode) == 116 ){         // F5
        e.preventDefault();
    }else if( (e.which || e.keyCode) == 120 ){   // F9
        e.preventDefault();
        location.href = 'www.google.com'  // do something
    }
});

$(document).on("keydown", disableFKey);

Objective-C 字串相加 (stringByAppendingString )

使用 stringByAppendingString:

#import <Foundation/Foundation.h>
int main(){
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSString *firstName = @"Wwfwwf";
    NSString *lastName = @"Liao";
    NSString *fullName = [[firstName stringByAppendingString: @" "] stringByAppendingString: lastName];
    NSLog(@"my name is %@\n", fullName);
    [pool drain];
    return 0;
}

result:

my name is Wwfwwf Liao

使用 stringWithFormat:

NSString *fullName = [NSString stringWithFormat: @"%@ %@", firstName, lastName];
