I'm able to iterate each text box control in "MainContents" by using the code below.
Q1: Is there a shorter way? (to get all controls in "MainContents"?)
For Each ctrl As Control In Page.Controls
For Each subctrl As Control In ctrl.Controls
For Each subctrlsub As Control In subctrl.Controls

i have 6 textboxes which i want to iterate.
they are however in a TD in a TR in a TABLE in a PANEL etc.
the only way i've figured out to iterate them is in this way:
this.Controls[0].Controls[3].Controls[7].Controls
that's not only errorprone, but also hard to come up with.
but this.FindControl (to find one by name) doesn't work either, does findcontrol also only search in the direct child, and not the whole hierarchie?
so basicly what i'm looking for is to iterate ALL controls in the page, no matter in which level of the hierarchie, to check if it's a textbox.

I tried with DISTINCT in the sql but that didn't work, so i think it may be better doing it through iteration? Can this be done?
I've got a datatable in a dataset which contains 44 rows. I can iterate through the rows and add the data to a placeholder - it's all there. However, if I bind a control (say a gridview or dropdownlist) to the datatable, all I get is one record (from the "middle" of the table). I get the same result when I create a dataview of the table - one row.

View 2 RepliesI am using listview which looks like below:
col1 col2 col3
ow1 textbox1 textbox2 textbox3
dropdown1 dropdown2 dropdown3
row2 textbox1 texbox2 textbox3
dropdown1 dropdown2 dropdown3
i.e. I have two rows and three columns in each column I have 1 textbox and 1 dropdownlist.
What I want is this, When a user selects something from dropdownlist , in selectedindexchanged event, I need to check if selected value from the sender dropdownlist is equal to any of the textboxes of the listview.
i.e. in selectedindexchange event of dropdownlist , I need to find all the textboxes of listview and then iterate them to match with selectedvalue.
Previously, I have done this for 1 row only by using namingcontainer but how to find all textboxes of listview .
I am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:

The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...

...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?
I have sqldatabase tables.I am reading table data and putting in a tabconatiner(wth tabs containing textbox, checkbox etc) specific to a client. If a client has more than one row i want to iterate through the rows and read each row data. Basically I want to use a button-click to read the next row data at put it in the tabs and so on. I used sqldatareader and a while loop.I can read the data but while loop iterates through the rows and show the last row data / i want to use a button to go to the next row and show data.
SqlDatareader reader=null;
reader=cmd.ExecuteReader();
while(reader.Read())
{
txtboxName.Text=reader["Name"].ToString();
}
protected button_Click(Object sender,EventsArgs e)
{
//I want to read row data in this button click

I was hoping to iterate through all the li elements of the ul checking whether NavigateUrl is equal to the current url. If it is, I was going to add a CssClass to give it a different appearance.
I think I know how to compare it to the page's url and to how to add the css class. I'm just not quite sure how you iterate through li items using a HTML Generic control.
I have a section of a form that I need to handle differently from the rest of form results. In the section that needs special handling I need to iterate over 3 form fields that have the same name. They have to have the same name, I can't change it. The section of the form I am referring to looks something like this:
<td><input name="Color" size="20" value="" type="text"></td>
<td><input name="Color" size="20" value="" type="text"></td>
<td><input name="Color" size="20" value="" type="text"></td>
Using C# I try something like this:
I try to handle it like this:
int i;
for (i = 1; i <= Request.Form["Color"][i]; i++)
{
colorName.Text += Request.Form["Color"];
}
Which leads to the following exception:
System.NullReferenceException: Object reference not set to an instance of an object.
How should I be handling form fields with the same name?

I have an html table in an aspx page (C#) that has columns like

I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this:

I want to create a summary page which itterates through each of the validation groups and outputs if it is valid or not by changing an associated text.The problem that I am having is that once one validation group fails validation all subsequent sections also report as failing - presumably as the page.isvalid is still holding the fact that a previous group has failed
View 1 RepliesI've created a wallboard application to display outstanding support calls for my ICT department. I've bound a number of gridviews to sqldatasources which execute a stored procedure. This is automated via asp.net ajax controls and partially refreshes the page/data every 30 seconds.
At the moment, when the number of records in the gridview goes over 9, the gridview automatically pages and shows the number of pages in the bottom right hand corner. The helpdesk can then VNC to the box which controls the screen and manually click to see what's on the next page.
What I am after is a way to programmatically (using the c# code-behind file) changing the current displayed page after 10/15 seconds or so, obviously if this is possible in the scope of the gridview. I trailed using javascript (and failed at jquery) of scrolling the gridview within a div, however this didn't work as expected.
Can anyone point me in the right example. I can't find anyone else querying this functionality via a quick Google.

I have a datalist and a hyperlink control that holds a url. A user creates this datalist through an admin website and not all of the hyperlinks have a link in them. The issue is how to hide the link that doesn't have a url in the database field.
code for the datalist:
<asp:DataList ID="dtlPromoEvents" runat="server" CellPadding="2" CellSpacing="2" RepeatColumns="1" RepeatDirection="Vertical" RepeatLayout="Table" >
<ItemTemplate>
<asp:Label ID="lblPromoHeading" runat="server" Text='<%# Eval("eventHeading") %>' Font-Size="12pt" ForeColor="#FFFF00" />
<br />
<br />
<asp:Label ID="promoDate" runat="server" Text='<%# Eval("eventDate", "{0:D}") %>' Font-Size="11pt" ForeColor="#33FF00" /> <span style="color: #33ff00; font-size: 12pt">@</span> <asp:Label ID="lblPromoTime" runat="server" Text='<%# Eval("startTime", "{0:t}") %>' Font-Size="11pt" ForeColor="#33FF00" />
<br />
<br />
<asp:Label ID="lblPromoDetails" runat="server" Text='<%# Eval("eventDetails") %>' Font-Size="11pt" />
<br />
<br />
<br />
<asp:HyperLink ID="eventLink" Text="Check this out!" CssClass="linkEvent" Visible="false" runat="server" Target="_blank" ToolTip="click to go check out what's happening!" NavigateUrl='<%# Eval("eventLink") %>' />
<br />
<br />
<br />
<hr style="width: 480px; height: 1px; background-color: #ff9900; border-color: #ff9900" />
<br />
</ItemTemplate>
</asp:DataList>
In the code behind I set the datasource with code and now I am stumped on how to reach into the items and control the visibility of the 'check this out' link based upon whether the db field has a link in it or not.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dtlPromoEvents.DataSource = LoadEvents();
//filter through the events and turn on visibility for the events that have a live link.
dtlPromoEvents.DataBind();
}
}
public static DataSet LoadEvents()
{
DataSet eventInfo = new DataSet();
string connectionString = ConfigurationManager.AppSettings["ConnectBeerGeeksDb"];
using (SqlConnection selectConnInfo = new SqlConnection(connectionString))
{
SqlDataAdapter adapterInfo = new SqlDataAdapter("SELECT [eventDate], [startTime], [eventHeading], [eventDetails], [eventLink] FROM [promoEvent] WHERE (eventDate + 1 > GETDATE()) ORDER BY eventDate", selectConnInfo);
selectConnInfo.Open();
eventInfo.Clear();
adapterInfo.Fill(eventInfo);
selectConnInfo.Close();
}
return eventInfo;
}
Adding the refined code that works on this url: [http://beergeekspub.com/events.aspx][1]
protected void dtlPromoEvents_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
// Retrieve the Hyperlink control in the current DataListItem.
HyperLink eLink = (HyperLink)e.Item.FindControl("eventLink");
// Check if a URL exists, if not then hide the control
if (string.IsNullOrEmpty(eLink.NavigateUrl))
{
eLink.Visible =false;
}
}
}
also the page load databinds the datalist -
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dtlPromoEvents.DataSource = LoadEvents();
dtlPromoEvents.DataBind();
}
}
