what is the errormessage?
if(document.getElementById.("dd1_dep_fabric").value=="--Choose Category--")
if this is the exact code you are using, remove . after getElemenById
and ifyou are having the dropdownlist int he content page, it must be prefixed with something like "ctl00_" . use this name in getelementbyid functional call as object name...(check HTML source by right clicking in browser window and select view source....and then look for the name for the control there )
hope it helps
cheers !

Hi all!
I am indexing Russian text with that code. I have a problem, when I try to search for words in different cases.
Search is productive, only if the word is in the same form, as in the initial (indexing) text. Help me please.
(Whether there can be it because Words in RussianStemmer.cs are stored in the coding KOI8-r?)

Hi ,
I don't know whether it will fulfill your requirement or not, but this is good calendar. And it is in javascript.
Here[^]
Regards 
|
|
|
|
|
AJAX toolkit has a calendar extension. You can use that.
|
|
|
|
|
you can create your own control with your specific functionality by extending the AJAX toolkit calendar control...
it is bit easy even for a newbee...
you can even put the checkpoints on date_change event to check for the start date and validating the end date or restricting the selection criteria of end date...
ask help if needed...
cheers !

nothing. Each time your server will get a hit and it has to do the processing, also user has to wait till the page posts back.
|
|
|
|
|
navneeth is right..
this is total wastage fo resources if unnecessary post backs are there... try to minimize the post backs and even the use of RUNAT="SERVER" controls wherever possible..
try to use simple HTML labels instead of asp:labels. it reduces server traffic and round trips and increases user acceptance to a very high level.
cheers...!

Hi all,
I have a page to remove Items from a database, the page layout is as follows:
---------------------------------
Item1 Description [Remove Button]
---------------------------------
---------------------------------
Item2 Description [Remove Button]
---------------------------------
.
.
---------------------------------
ItemN Description [Remove Button]
---------------------------------
Now, when I click on the remove button the item is removed from the database but when the page is submitted and reloaded, the removed item stays in the page contents (despite it was removed from the database) until you REFRESH the page. It seems that the browser reloads the page from the cache but I don't want this to happen, I want the changes to be reflected instantly.
BTW: the Item description and the remove button are wrapped in a web user control, I hope that this does not complicate the solution 
Thanks

just try:-
1. disable the response cachebility
Response.Cache.SetCacheability(HttpCacheability.NoCache)
2. bind the grid again on update command
may be helpful for you....

I am trying to databind an image to a repeater control. The problem is when i execute the procedure the image isn't appearing. Below is the code for both page and behind:
<asp:Repeater ID="rpt_content" Runat="server">
<ItemTemplate>
<h2><%#DataBinder.Eval(Container.DataItem, "Article_Title")%></h2>
<asp:Image ID="img_article" runat="server" ImageUrl='<%#DataBinder.Eval(Container.DataItem, "Article_Image")%>' />
<%#DataBinder.Eval(Container.DataItem, "Article_Content")%>
<%#DataBinder.Eval(Container.DataItem, "Article_Image")%>
</ItemTemplate>
</asp:Repeater>
Private Sub Repeater_Content()
Dim Select_Content As New SqlCommand("Select_Content", conn)
Dim da As New SqlDataAdapter(Select_Content)
Dim dt As New DataTable
conn.Open()
Try
Select_Content.CommandType = CommandType.StoredProcedure
Select_Content.ExecuteNonQuery.ToString()
da.Fill(dt)
Catch ex As Exception
Finally
conn.Close()
End Try
rpt_content.DataSource = dt
rpt_content.DataBind()
End Sub

hey mc....
use html image object instead..... it is more functional in real life...
<img src='<%# Eval("Article_Image") >' alt='' />

Hi, i'm creating a TextBox dynamically with the firing of a Button
but every time the page posts back the previous TextBox disappears. Is there
a way to retain that control and add the new ones below it?
Your help is greatly appreciated!

hi phivos,
the concept here is that the server recognizes the controls that are present in the design view of the page... and produces the HTML code for those.
the control you created is dynamic and will be maintained only if their is some logic to add that control every time. we can a collection object declared and add a key value pair for that control i.e. "textbox1" , "value in textbox entered by user"
and add it to that collection and keep that collection object in viewstate. everytime in page load, check for number of key-value pairs in that object and run a loop to add that much controls with id as key and TEXT as value for that key...
simple solution
cheers..!

if you are adding control(s) dynamically on the page, you will loos all the added controls on postback.
To avoid this...you need to understand the fundamental of aspx.
on the postback page is loosing all the dynamically added controls. Basically all the controls are available on the page, but page can not retrive them from viewstate.
You need to make rememebr the ids of dynamica added controls to the page.
ie. if you are added 2 textboxes on the page and giving ids like txt.ID="txt" +1 and for second txt.ID="txt" +2. so on the page load write the code to add the two textboxes and assign the same ids, so, page autometically will retain the text entered in the textbox on the postback.
Enjoy

I have finally learned how to program Windows Services and they have been going fairly well. I even was able to create a windows app that checked the status every minute of the 2 services I created.
Now my issue: I used a ServiceController component to expose the methods to display the Status of the services and to start the service. I wanted to create a web form that could do the same but the ServiceController is grayed out when I try to use it on the Web Form. Is there anyway that I could achieve the same goal in a webform as I did with the Windows form?
Looking forward to all responses.
