C# - Concatenate Different Values From A Specific Column To A Same Line

Jan 18, 2011

I Have a DataTable with a lot of Rows and Columns.

Some of these Rows have the Same "OrderId", actually these rows are almost the same, but I have a specific value in the "TagList" Column that I have to put in the previous row.

Making a unique Row with all the TagList values inside the TagList Column.

I'll give a example below:

Line 1:
ID: 1
Name: John
OrderId: 1500
TagList: AG75

ID: 2
Name: John
OrderId: 1500
TagList: BG99

I wanna do it:
ID: 1
Name: Mark
OrderId: 1500
TagList: AG75, BG99

ie: Concatenate the TagList's values when they have the same OrderId.

Forms Data Controls :: Gridview Doesn't Sort On A Specific Column After Updating

May 10, 2010

I have been struggling with this problem for a long time. Does anyone have any clue about this problem? I created a gridview and set the allowsorting to true. This gridview has four columns: Name, Position, StartDate, and EndDate. I want the gridview to be sorted on the EndDate.

Inside of the save event, I called the BindGrid() function to rebind the datasource to the gridview. The changes will shown immediately, but the problem is that the records are not sorting on EndDate. I have to refresh the page manually to get the view sorted.

<asp:GridView ID="gvInfos" runat="server"
CheckBoxEnabled = "true"
ShowEmptyTable = "true"
AutoGenerateColumns = "False"
CssClass = "gv_white"
DataKeyNames = "Id"
GridLines = "None"
Width = "100%"
AllowSorting = "true"
<asp:ButtonField CommandName="Select" DataTextField="Name" HeaderText="Name" />
<asp:BoundField DataField="Position" HeaderText="Position" />
<asp:BoundField DataField="StartDate" HeaderText="Start Date"
DataFormatString="{0:Y}" />
<asp:TemplateField HeaderText="End Date" SortExpression="EndDate">
<%# (((DateTime)Eval("EndDate")).Year == (DateTime.MaxValue.Year) || (DateTime)Eval("EndDate") == null) ? "Present" : ((DateTime)Eval("EndDate")).ToString("y")%>

AJAX :: CalendarExtender - Disable Specific Dates

Dec 15, 2013

This question is regarding one of your article on disabling future dates in [URL] ....

Your code in the above link disables(prevents for selection) dates for selection greater than today.

But I want to prevent users from selecting dates after a particular date say for example-after 13th October 2013, all the dates should be disabled.

I replaced this line

 var c = (new Date).setHours(0, 0, 0, 0);
var c = (new Date("October 13, 2013 11:00:00")).setHours(0,0,0,0);

in the javascript file(Extension.min.js).

But still it was disabling dates other than today.

Forms Data Controls :: Gridview Pass Specific Column Value OnRowClick (or) ButtonInRow To New .aspx Page?

Feb 24, 2010

.NET with VB I have a simple Gridview written with bound columns that gives a summary of all projects assigned to the user viewing the page.

I am struggling with passing the value of my project_ID column of a row that is clicked. I have looked around all day at different things, one involved using TemplateField with and ItemTemplate instead to fill my coloumns in stead of BoundField. This worked nicely to draw my Grid with the correct data from my datasource. I still struggled with two things.1. Selecting the row either button or ondoubleclick like event that runs VB code on my .aspx.vb page 2. Then the code to set a variable to the value for my project_ID columnThis is so frustrating, this was soooo simple in MS Access that was an on doubleclick event. That I simple set up set the project_ID.value = gblproject_ID and then called the new forum with the datasouce of that form filtered on the gblproject_ID. I am starting to think moving my MS Access DB online to .NET is far over my head.

DataSource Controls :: Accessing Specific Column In Database With Column ID With Table Adaptor

Jan 6, 2010

I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.

The current code:


Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?

Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

Forms Data Controls :: Formview Insert Adds All Null Values - Update Doesn't Update Values

Apr 12, 2010

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
