how to disabled the word label in my aspx page if my query is null... i dont like to show the word label in my aspx page.
im using c# .net
I have a label inside a formview that is not bound to anything.
Lets say I have a table of customers (with a key field called CustomerID), and then another table that has all their orders (with amount spent per order (OrderID) - based on CustomerID)
On the FormView there is a key field (CustomerID) (this is to be used as an INPUT parameter to a SP - which is to return the SUM of all the customers (Order_Totals). I could nest a view within a view I suppose to get this result, however, I just want a label to simply show this ScalarValue.
Basically, I want the label to show the aggregate (SUM) total amount each customer has spent on all orders. I have a SP called SumCost with two Fields (one a grouped by field CustomerID and the other a Summed Total of each customer's orders SumCost)
SELECT [SumCost] FROM [SumCost] WHERE ([CustomerID] = @CustomerID)
I test my SP and it works great, returning the value based on CustomerID - no problem.
My problem is getting the CustomerID passed into the SP on runtime (do I put it in FormView2_Databound) and putting the value into the label (CustTotalLbl) which is inside this form.
I have a gridview that I want to bind the results of a query to it once a user selects a value from a drop down list.
The query selects the same row from the same table but selects different fields based on the drop down list value selected
I get to the query selection but it does not refresh that page with the populated gridview.
Here's the code behind code
protected void ddlQuantity_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection connection = null;
connection = new SqlConnection(ConfigurationManager.ConnectionStrings["PSI_DB_1ConnectionString"].ConnectionString.ToString());
connection.Open();
String nEstno = Request.QueryString["id"];
int id = Convert.ToInt32(Request.QueryString["id"]);
string SQLquery = "";
switch (int.Parse(ddlQuantity.Text))
{
case 1:
SQLquery = "Select Quan1"etc...;
break;
case 2:
SQLquery = "Select Quan2"etc...;
break;
case 3:
SQLquery = "Select Quan3"etc...;
break;
case 4:
SQLquery = "Select Quan4"etc...;
break;
case 5:
SQLquery = "Select Quan5"etc...;
break;
}
SqlCommand Cmd = new SqlCommand(SQLquery, connection);
SqlDataReader Dr = Cmd.ExecuteReader();
if (Dr.HasRows)
{
gvEstQty.DataBind();
}
Cmd.Dispose();
connection.Close();
connection.Dispose();
}
I'm doing such a small web page that contain 4 main HTML div which should contain last 4 NEWS from a SQL Database.so I've designed them, and put in each on a label control, and an Image control.and to bind information from the SQL to them, I've used (DataView) object, and using a loop from 0 to 3 I've get the data I need.but I believe that way is not the perfect one! so I need something more clear and effectiveness!

View 5 RepliesI got stuck in the following problem. I am using cascadingdropdown ajax control and binding data into dropdownlist from database. I have done to display the data from database. Now I want to display the data, which is related to the item which I selected from dropdownlist, to 'Label'. ex) I have a following table in database.If I select '2' from the dropdownlist, I want to display 'Taro' to the label. If '1' from the dropdownlist, 'Ken' to the label. ID name 1 Ken 2 Taro I changed 'AutoPostback' property of dropdownlist to TRUE,then when I run the page and select the item from dropdownlist, error occured. Error messege is as belows. Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using in configuration or in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. If there is another way to display the item into a label without postback, or someone knows how to sort out this problem,

I'm trying to write a SQL Query that will grab items from a database that match the username of the currently logged in user. They are logging in using Active Directory credentials through a forms-based login page. I decided to create an ASP Label that will hold the username of the person who has logged in and the login status control, code:
[Code]....
I added a statement to the Page_Load event that should automatically populate the field with that user's name, code:
[Code]....
However, I get the error "System.Data.SqlClient.SqlException: The multi-part identifier "lblUn.Text" could not be bound." when I attempt to load the page after logging in. How can I fix this? Also, I might need to place this in a separate thread, but can someone check my SQL Syntax on the query? I'm not fully convinced it will work properly when I go to load the page. Code:

I'm trying to implement a recipe search page that allows users to specify search criteria by selecting checkboxes that match desired recipe attributes. All the data is stored in a database uing tables with 1 - many relationships. Each recipe can have multiple attributes from any of 5 attribute tables. I want to find all the recipes that match the user-selected criteria and display them in a grid. For example, the user may want a breakfast (attribute 1) recipe that is made with fruit and milk (attributes 2 and 3), is low-fat and high fiber (attributes 4 and 5), and takes less than 15 minutes to prepare (attribute 6). The query for this example might look something like:
SELECT distinct recipes.name, recipes.difficulty, recipes.preptime, recipes.cooktime
FROM recipes, recipeMeals, recipeDishes, recipeFoodGrps, recipeNutrients, recipeFixTimes
WHERE recipes.id = recipeMeals.recipeId and recipes.id = recipeDishes.recipeId and recipes.id = recipeFoodGrps.recipeId and recipes.id = recipeNutrients.recipeId and recipes.id = recipeFixTimes.recipeId and recipeMeals.mealId in (1) and
recipeDishes.dishId in (5) and recipeFoodGrps.fdGrpId in (1, 6) and recipeNutrients.nutrAttsId in (2, 3) and recipeFixTimes.fixTimeId in (1)
I' can generate the SQL but can't figure out how to bind it to a grid control. No could I see how to get any of the data controls to build the query for me. Is there a way to say "execute this query and display the results in a GridView"?
I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
something like CallbackFunc(Eval("SomeField"));

I want to populate a label with the employees name when they enter a badge number in the source page but im new to programming and don't know how to tackle this. The database connection has been established and it is successful. just an fyi this is for a time sheet application.
string Badge = "100000" + Request.Form["xBadgeTextBox"];
string Date = Request.Form["xWeekDropDownBox"];
string Hours = Request.Form["xWlengthDropDownBox"];
if (Badge != null)

cmd.Connection = conn;
cmd.CommandType = CommandType.Text;

I have an entry page that contains a datalist. I also have an ascx user control page that when it runs on page load, renders an html table template which contains category information from an SQL self referencing table. When the SQL query run on page load, it bind the results to a datalist called dlCategory, and repeats for all rows that have no value in a field in this SQL table called ParentCategoryCode. The SQL table is called ServiceRequestCategories and basically consists of CategoryCode, CategoryTitle, and CategoryDescription, and may or may not have a ParentCategoryCode associated with it.
Records without a ParentCategoryCode are top level categories, and anything that has a ParentCategoryCode are second or third level categories. The way I have the data set up, it ends up being 4 rows that are returned and rendered as 4 html tables. Each one of these is tied to the user control, and each user control runs another datalist, and shows all CategoryTitle values for each Category that has a ParentCategoryCode (second level categories). This works when you click on a LinkButton for any CategoryTitle. This all works fine.
My question is, how can I use an SQL select query to plug the value of the CategoryTitle into a label called lblCategoryBreadCrumb on my main entry page? Here is my code, but it does not seem to work.
Protected Sub ShowBreadcrumbLabel()
Dim strSQL As String
Dim dsData As DataSet
Dim dtData As DataTable

I have the following code which writes to a Gridview:

Using the same methods of connecting to the database, how can I amend this code to write the result of a second query (which only returns a number) to a label?
sql_select = "SELECT auid FROM tbl_auAccount WHERE username='" & IarUN & "'"
'Step Three is Creating Connection Object and opening the database
'Add Error Trapping Later
con = Server.CreateObject("ADODB.Connection")
con.Open(data_source)
'Step 4 is to Execute the SQL Command
con.Execute(sql_select)
'Step 5 Done. Close the connection
con.Close()
con = Nothing
This works fine, but I want the returned id (which I will right code to make sure it is not null and that it is only one returned) to show up as a label (or the text of a label)
lblShowNEWUserauID.Text = ?
I am looking for simple asp.net code example showing a simple webform task.
When user clicks a button, a stored procedure fires which runs an update-table query (not pulling any parameters from the user) and returns a count of the number of rows that were updated when the query was run.
Within my stored procedure I have the parameter @RowCount=@@ROWCOUNT.
All sample data I have found online has been C# or VB, but nothing that I can apply to my asp.net program.
Again, this is a simple task that for whatever reason I cannot find examples of online.
I have a Dynamic Data Website that I created after watching the video tutorials on this website (I'm new to programming, but not computers).I have a SQL Table named 'Adult' that has a 'DOB' column. I would like to add an asp:label to the Default.aspx that does a LINQ to SQL query to determine if it's someones birthday today and if so display their name and age.
View 5 RepliesI would like a title label to only be visible if the bound data label is not empty.
<asp:Label ID="TitleLabel" runat="server" Text="Title:" /> <asp:Label ID="DataLabel" runat="server" Text='<%# Bind("Data") %>' />
So if there is no Data incoming to the DataLabel then I want both labels to be invisible.
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>
I have XML file named as "XMLFile.xml"
So how to write XML records in Label?
Is it possible to display or hide a label based on the text rendered in it?
I have a label that will display the value of a control on the previous page. If the value rendered is "0" then I want to hide the label or hide the label and one more label associated with it. (or if the value is more than "0" make it visible.
My problem is when a label's text property has a value without space and bigger than it's width property. -Mostly when i enter a link url- The text of label exceeds the width of label!
