Does anyone know how I can iterate through textboxes on a usercontrol and put the values into a list. This is what I have tried so far...

I 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 have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx

Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

I have a multi section form which the user can jump between sections to complete. Each section has its own validation group associated with it. 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 done this using bound controls like Repeaters etc but now I need to display information about a single file for example. SO i will pass the fileid in the querystring, then I need to populate some textboxes, autocomplete textboxes etc. and then save changes. what's the most efficient way of doing this?
View 13 Repliesi m new to asp.net 3.5 linq and dnt worked much on generics.i m using IEnumerable to return set of results.i m binding this IEnumerable type method directly to datagrid source then it works fine.But i dnt knw how to iterate through this collection??Same way i m using List<String> to return columns like this
public List<String> FindImageData()
{
List<String> lst = new List<string> { "" };
ISingleResult<Usp_Patient_Radiology_DisplayResult> imagedata = objimagedata.Usp_Patient_Radiology_Display(p_PatientID);
foreach (Usp_Patient_Radiology_DisplayResult h in imagedata)
{
string Imageid = Convert.ToString(h.ImageId);
string imagefilename = Convert.ToString(h.imagefilename);
string history = Convert.ToString(h.history);
string imagetype = Convert.ToString(h.imagetype);
string oprposundertaken = Convert.ToString(h.oprposundertaken);
string patientposition = Convert.ToString(h.patientposition);
string report = Convert.ToString(h.report);
string xfilmorn = Convert.ToString(h.xfilmorn);
lst = new List<String> {Imageid,imagefilename,history,oprposundertaken,patientposition,report,report,xfilmorn };
}
return lst;
}
but at front end again i dnt knw how to iterate through it.it returns only single row??
with dataset it was quiet easy to navigate but with linq to sql navigation through generic collections is tough.
I have programatically added javascript to HyperLink controls on all pages in my site from the Masterpage as it is served up.
I have a new problem. I have a Masterpage wrapper around html pages without asp.net controls in them. Using the Masterpage, I need to parse through all html hrefs in each page and add javascript to each link if it includes "http" or ".pdf". Can the Masterpage parse the text of each page and programatically change it?
I wrote(attempted) a sub to disable all linkbuttons in a column in my GV. It seems code #1 just disables the LB in 1 row only.

View 2 RepliesI 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:
[Code]....
[Code]....
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?
Actually what i am doing in my Data Access Layer dragging store procedure to TestDbml to display records and creating data context instance in BAL to retrieve records and my method in BAL is like this
public IEnumerable display()
{
using (TestDataContext db = new TestDataContext())
{
var display = obj.USP_Actor_View_Speciality(p_UserName, 1);
return display as IEnumerable;
}
Now the problem is that how can i iterate or fetch over the records and display accordingly in my Presentation Layer so that i could return all the field parameteres Like ield1=val.field1,field2=val.field2.
I am wondering if MVC offers a handy function to iterate through all areas. I know I can search the sub-directories of Areas to achieve this. I am just curious.

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?
Say I have a class:
public class TestClass

private String Str3;
public String Str4 { get { return Str3; } }
public TestClass()

Str1 = Str2 = Str 3 = "Test String";
}
}

I have an html table in an aspx page (C#) that has columns like
1.CheckBox 2.Text 3.Text 4.TextBox
I want to iterate through the table one row at a time and process (run a stored procedure based on column2) based on whether the checkbox is checked or not. How will I be able to do that?
I have a Telerik RadGrid with a GridTemplateColumn that contains a checkbox, as follows:
<telerik:GridTemplateColumn HeaderText="MINE" UniqueName="MyTemplateColumn">
<ItemTemplate>
<asp:CheckBox id="MyCheckBox" runat="server"></asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
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 have an asp website, and a dataset with a datatable. When I check I after configuring it it shows all the data.

I'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.
Gridview Code:
<asp:GridView ID="GridView1" ShowHeader="False" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
GridLines="None" CellPadding="2" Font-Size="35pt" AllowPaging="True" PageSize="9">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID">
<ItemStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="ASSIGNEES" HeaderText="ASSIGNEES" SortExpression="ASSIGNEES">
<ItemStyle Width="32%" Wrap="false"/>
</asp:BoundField>
<asp:BoundField DataField="title" HeaderText="title" SortExpression="title">
<ItemStyle Width="53%" Wrap="false"/>
</asp:BoundField>
</Columns>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FPConnectionString %>" SelectCommand="HDMonitoringOutstandingToday" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

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();
}
}

I'm trying to read all filenames from a specified (server- not client) folder, and insert all the filenames into a javascript Array. It should behave like the Directory.GetFiles method in ASP.NET C#. I created a new array, and I just need the loop method (Javascript or jQuery) to iterate in the specific folder, and insert all the filenames into the array.
View 2 Repliesi 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.
