I have some labels on my Page (e.g. Label1...Label100).
I don't want to loop through all Labels to check if Text property is = "" (or string.Empty, whatever), so this's my question - is it possible to use LINQ or Lambda Expression to get all "empty" labels ?
how can i access the labels from a list view when i submit the page? for example i have a ListView with 5 items and each item contains a label calles Label1 and i want to read out each of this labels when i push the submit button

When apples is selected i want the the label is become visible, just like if grapes is selected i want the grapes label to be visible.

View 2 RepliesI have placed grid view in update panel with first row as empty and it is not bound with any data base. Rather I have bound grid view with data table. Whenever I click on 'Add New Row' button, a new row is created in grid view there by retaining the data field in old rows but my problem is whenever I click on save button, at that time data of first row is not retried but I can get the data that is filled in second row and onwards. I have saved my data table in session and again retrieving it after each post back.

I have a page with a datalist on it, with an image button and some labels in the datalist item(1,2)..
I have some more labels on the page which get their values from querystrings(17,18)..
I have more labels which are empty (34,35)
On image click in the datalist item, i want the labels from that item to add with the labels outside of the datalist, and the last lot of labels to show this number..
Currently it doesnt do this. Here is my code:
protected void Page_Load(object sender, EventArgs e)
{
Label17.Text = Request["b1"];
Label18.Text = Request["b2"];
}
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
DataListItem item = ((Control)sender).NamingContainer as DataListItem;
Label Label1 = item.FindControl("Label1") as Label;
Label Label2 = item.FindControl("Label2") as Label;
Label34.Text = (int.Parse(Label1.Text) + int.Parse(Label17.Text)).ToString();
Label35.Text = (int.Parse(Label2.Text) + int.Parse(Label18.Text)).ToString();
-7vf- I write a program by c# to check and retrieve data from database
The problrm:I have one table(1), I want to make update for that table(1) that is by compare the one column in table(2) with the right side from one column in table(1), so if there is any similarity it will retrieve the data and if there is no match just it will make the record empty(null) "the data type of retrieving columns: number 'double'", but the problems is:
I try to retrieve 11 columns, 7 of them are empty .the program run with out error ,but it will retrieve some records with full data 11 columns, but some of records has only 5 columns have data and 7 columns are empty (these records when I run the program did not retrive any columns, it give me empty records!!)
this is the code :
while (or.Read())
{ or.GetValues(field); OdbcCommand oc2=null;
[code]....
I want to retrive all data which are empty or null and all data
When retrieving values from Gridview empty cells, you will get " " instead of a empty string or null.
Someone once change the columne's properties as following, but it doesn't work
ConvertEmptyString > true
HtmlEncode > false
HtmlEncodeFormatString >false
One solution is to check if the cell value is " ". If so, assign it an empty string. But this approach looks awkward.
I have a list which is defined as List<SoftwareTitles> softwareTitlesList = new List<SoftwareTitles>();
and the SoftwareTitles is a class which is defines as follows:
public class SoftwareTitles
{
string softwareTitle;
string invoiceNumber;[code]....
And now I'm adding the values from the sql server database to the list defines as follows:
public List<SoftwareTitles> SoftwareListRetrieve()
{
ConnectionToSql con1 = new ConnectionToSql();
string connectionString = con1.ConnectionStringMethod();[code]....
I want to find out the software title for every occurence of invoice number by looping through List<>. And I don't know how ? I have tried to loop through the List<> by the following code. I wanted to use something like contains i.e., softwareTitlesList[i].contains but seems like there is no such property or method
for(int i=0; i<softwareTitlesList.Count;i++)
{
softwareTitlesList[i].
I'm new to MVC and trying to follow along to the 10-minute overview video at: [URL]. I'm running into a couple of problems starting at the 3:30 mark:
1. When I type in the following code as seen in the video, the DB class isn't found? Is there some namespace I'm meant to include or something?
[Code]....
2. At 3:53, I cannot select my model to create a strongly-typed view - the dropdown list is empty.
I have defined a class:
public class ProjectSitesForGrouping
{
public int ProjectID { get; set; }
[code]...
I'm using one Sublayout (Sitecore) and have a placeHolder that currently holds 2 webcontrols. I want to access the Label from one Webcontrol to the other Webcontrol.Do i have to find the Label recursively or can i just access the Label on another way? I tried different methods like:
this.Page.Findcontrol
this.Parent.Findcontrol
Label lblSearchTerm = (Label)this.Parent.FindControl("lblSearchTerm");
Label lblResults = (Label)this.Parent.FindControl("lblResults");
any result as being Label lblSearchTerm = null.

How to implement all controls to localize languages in a Web Page??
View 7 RepliesWhat I am trying to do here is I want to add the dynamically created labels in the Panel on the Webpage and not directly on the Webpage. My panel has scroll bars and thus when I scroll horizontally or vertically only the background moves whereas the labels are static to the page.
And some labels are even visible on the panel borders on scrollbars (some on the page outside the panel) which are suppose to be placed inside the Panel. So when I scroll either of the ways even the labels should move along with the background image.
So how can I make these labels stick to the Panel and not the Page? How do I do it?

I'm new with the MVC framework and I was wondering what you think is the ideal way to retrieve data and list it on a page. Specifically, I'm referring to data used in report type pages, not lists of movies, books, or other clear 'objects'.
Most online samples seem to suggest using ADO.net Entity Data Models & LINQ which are automatically built by the wizard using the DB schema - and that seems great for things like movies/books, but doesn't seem so intuitively 'correct' for random data needed for a report.
Update:To be more specific, I basically need to take a set of rows from a Sql server view and display them on a page. Some of it just in a list, and some in graphs (planning to use the .net charting control). I realize what I'm doing is very simple, I'm just not sure what the best way of doing it using the MVC framework is. Hope that clears it up a bit...
