I have a gridview connected to sqlDS and a dropdown Dropdown contains a selection Last 30 days, 60, 90,180 etc... How to write a Where Statement that reflects this? If I want to view the last 60 days of records
WHERE RecordDate >= TodaysDate - 60 days, but as a parameter
WHERE RecordDate >= TodaysDate - @SelectedValue days
Is this a clear explanation?
Some of you might know that I am currently working on a simple blog (thread with full details here). There is a slight problem however ! After achieving the post filtering, the blog doesn't show any posts, unless; I click on of the categories. I was hoping that the blog would show ALL posts at first, and THEN if a user clicks a Category, the filtering would occur. So I went over the code again, and there was this:
[Code]....
The DefaultValue="0" caught my eye, so I changed the number to "1" and I got all the posts in the [ General ] category, I tried "2" and I got the posts from the [ Programming ] category ..etc So I was thinking how I'd go about solving this problem, because (initially) I want the posts from ALL categories to show. Is it possible to add more than one defaultValue ? for example: DefaultValue = "1,2,3"
I have tried the above and it gave me errors, so obviously it doesn't work that way, but is there another way of adding more default values ? Or could you think of a different way to make all the posts show ?
I am trying to add a textbox search to a gridView. However I am recieving the below error
View 3 RepliesI have this code in an .aspx file, within a sqldatasource control.
<asp:controlParameter
Name="WH"
ControlID="rblWH"
DefaultValue="DL"
Type="String"
Size="2"
Which currently uses a 2 character code from a radio button list as its value. It is used as a parameter for a stored procedure. Somewhere else on the page I have a combobox called cbTripPick with that 2 character code embedded within its text property. I wish to use that 2 character substring as the control parameter instead of the above. Can I do something like this ?
<asp:controlParameter
Name="WH"
ControlID="cbTripPick"
PropertyName = "some function or expression or eval that will give me the 2 char. value from the cbTripPick control"
DefaultValue="DL"
Type="String"
Size="2" />
Is it possible to declaratively set the propertyname to some dynamic expression which will get me what I want? Or should this all be done programmatically?
Here my question is very simple. That what I want to do is to select a date using asp.net calender control and insert into textbox. Both the controls are in the InsertItemTemplate of the FormView.
1. Page1.aspx has a textbox and an image for calender.
2. Calendar.aspx is to select any date and with the help of session it should go back to its parent page in the text box and dispose itself.
Achievement:1. From Page1.aspx when i click Calender image, perfectly a new page Calendar.aspx opens.
2. On Calendar.aspx page, date selection is also OK.
3. Using Session, the date is perfectly transfering to next page.
Problem: 1. When I select date from Calendar.aspx it is not transfering back to Page1
in textbox.
2. Secondly when I select date from Calendar.aspx it is not disposing itself after date selection.
I am filtering dataview using my Date Column but the result is not proper because the Field value also stores time, so I want to convert this Date Field to only Date during Filter. How can I achieve this? Here is my code. And the actual value I am getting in the Dataset Field "CreationDate" is a DateTime field which is like
2010-01-21 14:35:25.203
2010-01-22 12:55:18.033
2010-01-26 12:10:06.990
But I only want to neglet time value and want to compare Date only.

I have some issues about retrieveing and storing date information to my database (ms sql server 2005).My data column is a DateTime, and i have set my web.config globalization culture is set to "en-gb"
When i retrieve date from the datebase it appears as dd/MM/yy, that's fine. But i cannot insert a new date as same format?! It will only accept MM/dd/yy or yy/mm/dd.Right now i'm using this code to correct the error:

View 1 RepliesI am having a problem with using A Gridview SectedIndex or value in a sql ControlParameter. When I select the row it does what I need it to except it shows that there is no data.
but if I add Default Value of 1 the data shows up, but it needs to read from the Gridview.

I even added sqlDataSource.DataBind() in the SelectedIndexChanged Event to see if that would fix it but - No! I used it with a DropDown and it worked only when I use AutoPostBack = true of course.
I am using the ajax toolkit calendar extender control with the asp.net button for the postback event. the functionality is after selecting the date, clicking on the submit button will call the button event. now I need to obtain the same thing without clicking the button and on the date selection. ie, on selecting or closing the calendar control the postback event has to fire. how too obtain this? calendar and the button are placed in the user control.

I have an ObjectDataSource with a number of parameters. These parameters are binded in my FormView EditItemTemplate and the ItemTemplate. My Stored Procedure column names in my ItemTemplate are different to the Bind properties used in the EditItemTemplate. This is obviously throwing an exception when I update a record.
Instead of using Bind("Columne Name") in my EditItemTemplate how do I use a ControlParameter to reference a TextBox in the EditItemTemplate?
I may be wrong but I'm trying to use the PropertyName=Controls but i do not know how to reference the Textbox in the EditItemTemplate.
i'm using Relational Tables and during Edit, my Drop Down list is a lookup column from the Master table, but when i try to edit it works and shows the records the only problem is that when i udpate, i get the error (Can't find control DDLSongs (my drop down control) in @AlbumID Parameter) below is the code for ref.

i have two tables (Albums,Photos).befor i want insert a record in a Photo table i must select name of album so i create a user control that have a dropdownlist and a datasource(Albums table) until when i select a name of album put AlbumID in a Property(SelectedValue) when i use this user control in details view in edittemplate i have an error
--->error could not find control 'SelectedAlbum' in ControlParameter 'AlbumID' my code id:
public partial class Admin_SelectedAlbum : System.Web.UI.UserControl
{
public string [COLOR="Red"]SelectedValue[/COLOR] {
get { return DropDownList1.SelectedValue; }
}
protected void Page_Load(object sender, EventArgs e)
{.........
how does AlbumID (photo table) set with value of property(SelectedValue) of Usercontrol?
I have following in many controls:
<asp:ControlParameter Name="SvcCluster_Id" ControlID="frmConfigEdit$ddlCluster" PropertyName="SelectedValue" />
Everything was good before I bumped into the problem when declarative binding (SelectedValue='<# Bind("SvcCluster_Id") >') produced the error, because value has not been found in the list. So i moved binding to the code:
protected void frmConfigEdit_DataBound(Object sender, System.EventArgs e)
{
if (frmConfigEdit.CurrentMode == FormViewMode.Edit)
{
var svcCluster_id = DataBinder.Eval(frmConfigEdit.DataItem, "SvcCluster_id");
var ddlCluster = (DropDownList)frmConfigEdit.FindControl("ddlCluster");
if (svcCluster_id != null && ddlCluster.Items.FindByValue(svcCluster_id.ToString()) != null)
{
ddlCluster.SelectedValue = svcCluster_id.ToString();
}
}
}
But now seems like this happens later than ObjectDataSource tries to access frmConfigEdit$ddlCluster...
How to manage this?
I wouldn't like to move everything to the code (I mean creating Control parameters, etc)
p.s. Oops, actually it works ok for DataBound event! Sorry.

I have a problem, I need to get a date from an SQL database using a dataset.xsd.
To do that, I have created a query in the TableAdapter called GetDataByFecha:
SELECT fecha
FROM T_Tickets
WHERE(fecha = @fecha)
in C# I do this:
DateTime T_fecha;
T_fecha = Convert.ToDateTime(ticketsAdapter.GetDataByFecha(fechaTicket));
but, when I compile it I get this error:
cannot convert a 'T_TicketsDataTable' object to 'System.IConvertible' type.
