I have 2 methods I tried to iterate through all my textboxes in an asp.net page. The first is working, but the second one is not returning anything. Could someone explain to me why the second one is not working?
This works ok:

I have some code that iterates through three datalists when they are bound and looks for certain values. If those values exist it hides that particular row in the Datalist. This is working beautifully, except the last row in each datalist is unaffected by the iteration. So for example if I have the following numbers 2, 5, 6, 5, 7, 5 and I want to hide all the rows that contain 5, it produces the following: 2, 6, 7, 5.
Here is my code:
Dim dlitem As DataListItem
Dim tb1 As Label
For Each dlitem In OnHoldDataList.Items
tb1 = CType(dlitem.FindControl("LocationLabel"), Label)

You know if TextBoxWatermarkExtender attached to a password textbox it shows blank points instead of hints.
in conclusion, is there any working procedure for ajax or javascript code that can change textbox mode from password to singleline back and forth on focus and on exit of the password textbox hence to see the watermark ?
I have a set of CalendarExtenders. When I include my javascript file, the onclick event which pops up the calendar no longer displays. My javascript file adds onchange events to those text boxes.
View 1 RepliesI've got some labels in a listview, 2 per row. One contains a title, the other information. I want to change all the titles when the user presses a button that fires the ListViewSelectEventArgs. I think they have the same ID since they're from the ItemTemplate, so I thought that's how'd I target them. I'm just not sure how I'd step through the listview.
Here's my attempt:
int x = 1;
for( int i = 0 ; i < this.lvSteps.Controls[0].Controls.Count; i++ )
{
if ( this.lvSteps.Controls[0].Controls[i].GetType() == typeof(Label) &&
( this.lvSteps.Controls[0].Controls[i].ID == "lblStepNumber" ||
this.lvSteps.Controls[0].Controls[i].ID == "lblNewStepNumber" ) )
{
Label lbl = this.lvSteps.Controls[0].Controls[i] as Label;
lbl.Text = "Step #" + x;
x++;
}
}
Currently, I have a list of PhoneNumber objects that I display. Here's an example of the output of the view:
[Code]....
Notice the naming of these elements: name="existing_phone[labels][6]", name="existing_phone[numbers][6], name="new_phone[labels][]", name="new_phone[numbers][].Back in the Classic ASP days, I recall being able to do something along the lines of:
[Code]....
And that would give me a 2d array of phone numbers to work with. This doesn't seem to work in .NET. Has anyone tried to do something similar that can point me in the right direction?For new phones, I should simply be able to iterate through each item and insert into the database. For existing phones, I should be able to update (or delete if the label or number are blank) records based off of the id number supplied in the array.OR..if anyone has a better, alternate solution, I'm open to something else.
I have a DataView which filters
inputView.RowFilter = "isnull(" + ID1 + ",'')<>'' and isnull(" + reason + ",0)=0";
after this filter i have to update "IsVerified" column of inputView to "1"
Is there something in LINQ to execute the following?
inputView.RowFilter.ForEach(x=>x.Field<IsVerified> =1);
I have a string of information that I need to parse. I've written a regular expression to find the information I need. Now how would I iterate through each regex match and add it to a list (or do something to it)?
View 2 Replieshow to iterate through the rows in a database table without using a GridView? I have a DataSet and a SQLDataReader, but I can't iterate through rows using the SqlDataReader.
View 13 RepliesSystem.InvalidCastException iterating through Viewdata
I need to replace the code

for dropdown in the following manner for some reason.
<% foreach (Hexsolve.Data.BusinessObjects.HSPartList item in (IEnumerable)ViewData["Parts"])

<%=item.IssueNo %>

I am getting error converting SelectedList to IEnumerable) Error: Unable to cast object of type 'System.Web.Mvc.SelectList' to type 'System.Collections.Generic.IEnumerable`1[Hexsolve.Data.BusinessObjects.HSPartList]'. Is this the right way to iterate through viewdata[].
this is general to any operation calling an SQL server, or anything requiring an open connection at that.Say I have anywhere from 20 to 1000 Select calls to make for each item in data being looped. For each step, I'll select from sql, store data locally in a struct, then proceed. This is not a very expensive call, so should I keep the connection open for the entire loop? Or should I open and close every step? How expensive in run time is opening a connection? I would think it'd be better to keep the connection open, but would like to get the correct response for this.
View 4 RepliesI 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

I have a DataTable available with me which contains thousands of rows. There is a column called EmpID which is containing '0' for some of the rows. I want to remove them from my current DataTable and want to create a new correct DataTable. I cannot go row by row checking it since it contains huge amount of data.
View 6 RepliesI've done this using bound controls like Repeaters etc but now I need to display information about a single file for example.

View 13 RepliesI was building an application for a project with .NET 3.5 and I noticed a weird behaviour of the List.Add method:
I have built my own class to organize data pulled from a database, and I use a while cycle to iterate through it.
However, when I List.Add(item), the whole content of the list is substituted with the last content pulled.
An example:
Suppose you have 3 users in a DB, each one identified with an ID and a username:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
and you have a "Users" class defined as
public class Users
{
private Int32 iD;
private String username;
public Int32 ID
{
get { return iD; }
set { iD = value; }
}
public String Username
{
get { return username; }
set { username = value; }
}
}
So you write this function:
[... SQL definitions - sdr is a SqlDataReader ...]
List<Users> userlist = new List<Users>();
if (sdr.HasRows) //There are users
{
Users user = new Users();
while (sdr.Read())
{
user.ID = sdr.GetInt32(0);
user.username = sdr.GetString(1);
userlist.Add(user);
}
}
What you expect (I expect) is userlist containing:
| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |
What I actually get is, instead
| ID | username |
| 3 | Paul |
| 3 | Paul |
| 3 | Paul |
i am having Nested Gridview and from the child Grid i have to select the checkbox to retrieve the id's by iterating the child grid and that to on the Button Clik which is outside the Gridview.
View 2 RepliesI'm having trouble with something that is (or should be) fairly straight-forward.
I have a recursive method that traverses an XML file, writing out the element tag names and values.
This is a snippet from the XML file:
[code]
<root>
<all_companies>
<company_group company_group_ID_attr="1">
<company_group_name>Cleaning</company_group_name>
<company_group_ID>1</company_group_ID>
<company company_ID_attr="2">
<name>Bloomburg</name>
<company_ID>2</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="4">
<name>Morris</name>
<company_ID>4</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>3</employee_ref>
<employee_ref>1</employee_ref>
</employee_refs>
</company>
<company company_ID_attr="7">
<name>Ajax</name>
<company_ID>7</company_ID>
<Address>blah blah blah</Address>
<employee_refs>
<employee_ref>4</employee_ref>
<employee_ref>2</employee_ref>
</employee_refs>
</company>
</company_group>
</all_companies>
</root>
[/code]
I use the following XPath expression to access the first <company group> tag:
"root[1]/all_companies[1]/company_group[1]"
On the first call to the recursive method ("swrite_for_select_certain_stuff"),I see with the debugger that I reach the <company_group_name> tag. A recursive call at that point takes me to the text node within the tag ("Cleaning"), but it is a text type node (not an element), so it returns without writing anything to the output stream.
On return from that second call, things go wrong. The Iterator within the while loop returns false for the MoveNext method, when it should have moved to the <company_group_ID> tag (or so I think it should).
Am I missing something here?

I'm doing this in my Master Page. I want to access a Linkbutton within the Gridview and set the enabled = false; I tested this and it works all the way up to the first if statement.If I insert a response.write to get the frmctrl.ID, I get all of the controls on the page. BUT, can't get the controls within the gridview.How do I get the contorls within the gridview? I prefer not to do this using Findcontorls and esp setting the control to Public.
I'd like to take the standard "List View" view in an ASP.NET MVC application, and convert all of the "Labels" to "TextBoxes" and then save any changes made to each record.The end result would function very similar to the List View in Access. I couldn't find anybody doing this, To be clear, I do not want an Edit/Delete button for each record, I want one "Save" button for ALL records at once.
View 1 RepliesI have a grid where in insert/edit mode you can update the item for a person's names.
I've been asked to provide validation to ensure only alphanumerics are added.
After talking with a colleague we were thinking only validation for length should be done.
The user should be able to enter any characters they like.
Does this sound correct? I understand some names could contain special characters etc.
how do I do the most simplest thing like get the values from textboxes in a form and bind them to my lets say product or whatever object?
I work with MVC 2 and NHibernate. I seen some examples where they work with linq 2 sql and what they do is just save the product in the controller like _repository.Save(product);
they use active record and is that why that is possible? And in this example they use on the beginform like this
