Not sure what you mean by that.
However, the following regex will ensure the string ends with a dash followed by exactly 4 numeric digits.
-[0-9]{4}$
If you want to ensure the whole string is zero or more numeric digits followed by a dash followed by exactly 4 zeroes, this would work:
^[0-9]*-0{4}$

Hello All,
To accomplish the autocomplete feature into our website, I went through the whole process of setting up AjaxControlToolkit on my computer. I set up a ADD TAB on Visual WEb Developer 2008 Web Express. Added an item and selected this dll. Was able to create the ajax controls.
Now when I set up a new web site, ajax and non-ajax web sites, for some reason I am unable to access these controls. Do I need to add the reference to the ajaxcontroltooklit.dll reference to this new web site project? I can see all the controls but on the design page when I try to drag an icon over, it does not let me .
Thanks!

It is not to with the autocomplete but the entire AjaxControlToolkit.dll itself.
I am unable to reference it any other newer projects, it comes greyed out on the toolbar. Do I need to add a new reference each time I want to use the Ajax controls?
Thnaks.

that is why I have the Ajax Toolkit in a special folder. So each project can Find it (for the components left). Of coure you have to reference the dll in each project
In Word you can only store 2 bytes. That is why I use Writer.

Hi all, I need help validating textBox whether the user input was a correct date format and not empty. I can use RequiredFieldValidator to make sure the textbox is not empty but how do I know is correct date format which support my database.thanks,
|

|

Why not use a calendar control rather than a textbox? The date will already be formatted.

Hi,
I have a grid which is bound to data coming from a service at runtime.
The issue is every time i select next page number the page goes blank.
My code is as follows: for grid in aspx
<div>
<asp:Label ID="Label1" runat="server" Text="Searching....." Font-Bold = "true"></asp:Label>
<asp:GridView ID="grid1" runat="server" OnPageIndexChanging= "grid1_PageIndexChanged"
AutoGenerateColumns="False" Enabled ="false" AllowPaging="True" PageSize="5">
<Columns>
<asp:BoundField DataField = "Name"/>
<asp:BoundField DataField = "ID"/>
</Columns></asp:GridView>
</div>
the codebehind(.cs) is typically is as follows:
on pageload:
grid1.Enabled = true;
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("ID");
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
dt.Rows.Add("Jack", 1);
dt.Rows.Add("Jill", 2);
grid1.DataSource = dt;
grid1.DataBind();
protected void grid1_PageIndexChanged(Object sender, GridViewPageEventArgs e)
{
grid1.PageIndex = e.NewPageIndex;
grid1.DataBind();
}
what am i missing here

I think you need to include your Page_Load code inside If( ! PostBack ) { } block.
Please try this.

yes my code is inside if (!IsPostBack) block..
but evrytime i click say page 2 the screen goes blank.
|
|
|
|
|
I can't reproduce this behaviour. When paging through the Grid the screen doesn't go blank. Im using VS 2010.
Maybe it has something to do with the data source you've bound to the control?
|
|
|
|
|
my datasource is a list of objects returned from the service.
Since I need to format it before displaying I convert it into a datatable and this datatable is datasource to the grid. I have stepped thru and found that datatable has populated fine with all the values. even the page comes up fine with all the data and 123 page links down. it's when i click page 2/3 link in pager that it goes blank. am using vs 2008 .net 3.5

You should probably separate all the three subroutines. Have the !(PagePostback), datagrid itself, and the Grid1_PageIndexChanging all separate and not in one sub.
|
|
|
|
|
my page load checks if it's not postback it calls the gridview load which does what i've posted and i have seperate event handler.
|
|
|
|
|
I had the same issue. I had to literally re-bind the entire datagrid for it to work. It worked for me, and was working under time cruch, I stuck with it.
|
|
|
|
|
what do u mean by rebind, rewrite the code?
|
|
|
|

Hi ,
Your Page_Load checks if it is not a postback right ?
This means your code sets the DataSource property of your grid ONLY once and that is when the page loads for the first time.
Please write the code "grid.DataSource = dataTable;" just before the code "grid.DataBind()" and let me know if it works.
Always make it a habit to set the DataSource of a grid just before calling the DataBind() method on the grid.
E.g. I would always code method like "BindPersonsData()" in my application which would be like -
private void BindPersonsData()
{
grdPersons.DataSource = GetPersons();
grdPersons.DataBind();
}
private DataTable GetPersons()
{
DataTable dt = new DataTable();
//logic to get data
return dt;
}

Hi,
how I can get the birthday from column in database ( as datetime type ) and display it in a separate dropdownlist one for day and other for month and textbox for year .
I want get the information to update on it .
thanks .
|
|
|
|

Is it stored in the database as a DateTime? If so then you get the same way you would get any other column. Once you have the DateTime object you use the properties the structure, Day, Month, Year to get the constituent parts.
In these situations I usually rely on a little trick I like to refer to as Reading the Documentation, or as some abbreviate it, RTFM
I know the language. I've read a book. - _Madmatt

Why you aren't using Calendar1 control?
If you have to split birthday value in controls then use Year,Month,Day SQL Functions.
e.g
select year(birthday) from mytable
select month(birthday) from mytable
select day(birthday) from mytable
