Forms Data Controls :: Making A Self-updating Friends Datalist?
Mar 18, 2010
i'd like to have a datalist displaying which friends a user has that are "online now" or at least "were online within the last 5 minutes"
assume i have a database of user profiles, and another of friends, and i can succesfully get a list of the user's friends into the datalist already. i also have a "lastlogin" datevar that i can easily pull that'll tell me the last time this user was logged in.
i want this datalist to auto-update without the user having to do it, or notice, unless online users change. it shouldn't refresh the entire page or anything, i want to tuck it away in a corner for the user to check on while his browser sits on the page if he wants.
i have no experiencing setting up any kind of automated or timed interval process for my .net c# site, and i'm generally a novice so please be gentle. where do i start this?
Probably a fairly simple one. Just need to know how I can make reference to controls in the HeaderTemplate of a DataList. I've got a form in there that I need to get the data from.
I have a requirements ,in that i am using nested datalists. here the problem is i am try to updating inner datalist,but i am unable to edit the inner datalist .In the child item child datalist is not appearing?
I have a DataList that on Update calls a function "DataList1_UpdateCommand" to update the data
OnUpdateCommand="DataList1_UpdateCommand"
It does not actually update the new value typed in. I placed a debug on the line below, but the text in the "FieldBalance" displays the original value and not the updated value, but the web pages does display what I typed in and not the original.
Dim FieldBalance As TextBox = CType(e.Item.FindControl("txtBalance"), TextBox) Below is the DataList code and the DataList1_UpdateCommand sub

The problem is that i have a search page. Access Database holding the information. I have a Access Datasource on the page with a Datalist to show the data. I need to find a way on setting it up to says "Sorry no results found" when the is no results. i am unsure on how to do this though.
Am building a Form for out intranet that runs on ASP.NET and C#, it is to be a survey from a SQL database. I have the connections setup can pull informations/Questions from the database. I am having a problem with setting up radio buttons within a datalist, ive never done this and i know they require unque names.
It is to be 4 radio buttons per question where only one can be select, i know how to group just not via a datalist with unique names
I am trying to place a datalist inside datalist. I managed to place a datalist inside gridview but not datalist inside datalist.
Below is the code I am using to bind the datalist into the master gridview, I am trying to change this code in such way it will be right for datalist inside datalist but so far I did not succeed.
i have a datalist . that is contains 7 columns in repeat layout .when i have more from 7 columns , datalist style is normal .but when i have smaller than 7 columns ! data list style is not normal,
because there are some empty columns without specific schema.
How i can make a datalist > when i have 1 columns in my datalist my first layout width be 100% ;
I'm just struggling with a lot of little things in the web app so I'm checking up with all kinds of stuff to make sure i'm not breaking it cause of stupid problems.At some point in my web app (trying to keep it mostly Asynchronous) I have to update the list in my RadComboBox because something was added. Do I just need to call RadComboBox.DataBind() again? Since I don't explicitly use its datasource(I do it in the manual insert using a string fashion) object to insert my new record do I need to tell that to update? The list just doesn't seem to update when i just call databind so I feel like i need to have the datasource recheck for entries or SOMETHING
I would like to add a column in my datagridview that takes the value from the database and asigns it to the text of a linkbutton or make it a hyperlink. i know how to handle getting the value from the row but dont know how to make a value a link, or set the text to a link button
I have a page where my user enters a search term and submits it against my database. What I want to happen is when the result(s) return, I want headings to pop up over my gridviews. For example, I want "Photographs" to appear over my gridview for photographs, "Documents" to appear of my gridview for documents, etc...
When I run my page, those headers are already there, even though I have not conducted a search yet and my gridviews have not populated. If I go into properties and select visible=false, they never show up, which is not exactly what I want either. I have read about literals, textboxes, panels, and have confused myself.
Data entered in textboxes is not getting updated in database. In debug mode I see that text1 and text2 in ItemUpdating event contain the same values as they had before calling ItemUpdating.
I am trying to make columns of a gridview invisible if they contain a space. The page contains a combo box which users can change. This causes a change in the data in the gridview. I use the following code:
[Code]....
[Code]....
What is working: On the initial page load, the correct columns are deleted. However, if the user changes the combo box, and the gridview has different data loaded into it, it cannot make visible what was previously invisible. I added the ...visible = true line to get round this, but when I load the page, it seems to get locked into a loop forever, and the page never loads - this is why the line is commented out.
This should be soooo simple, but it's making my brain smoke. I've tried writing the results on whether there is a space in the cell to an array, and then using that to make the columns invisible. I've tried doing this in different events, but it always has the same problem.
I suspect that if I can find out how to reference the contents of the gridview from outside its events, it may be easier.
I have a issue, and i need your opinion how I can do it. May be someone from you did the same.
for example, we have structure of property address what stored in database:
0. Property type
1. Region
2. Postal Code
3. City
4. Street
5. List of properties
I need to build SiteMap with work with SiteMapPath.
If we have small count of records in database this is not a problem but what I need to do if in database present extrimally big count of element for each node (from 0-5) ?
make query to each element and build site map this is not good for two reason perfomance and count of queries to DB.
I'm using a listview control to show a list of categories/subcategories <%# Eval("SubCategory1")%> When the user clicks the SubCategory1 link, the list view should fill up with the next subcategory, SubCategory2. The problem is off course that <%# Eval("SubCategory1")%> is hard-coded. I need it to change to <%# Eval("SubCategory2")%>...and so on, as the user is drilling down into the sub-categories.
So is there a way to change <%# Eval("SubCategory1")%> dynamically?
I have a page with one dropdownlist and one grid. when dropdownlist's selected index is changed i generate a BindingList with some data based on the dropdownlist's selected value. this BindingList is binded to the GridView with one readonly column (eg: Item) and one column for entering data (eg: qty).
i need the Qty column to directly editable (without pressing edit, then goes to edit mode). and update this values back to BindingList's corresponding Item when the qty cell's focus is changed.
I have a gridview that has both a select and an update statement. One of the cells is a date cell, and the other is for numerics only. Is there a way I can do this? At the moment, anything can be keyed into the cells and this results in an error as my update stored procedure expects a date value and a numeric value respectively.
I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
BTW i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.
I have a gridview that allows you to select and a details view show up at the bottom. Is there a way to make the details view show in a new window instead,
