If Statement Within A Formview Control?
Jun 10, 2010
I've got a form view that gets it's data from an access database:
I need to make the text of a label display Correct if the contents of the database field is 1 and Incorrect if it is 0
I was hoping I could turn the label's value to a string
(like this: <asp:Label ID="RightWrongLabel" runat="server" Text='<%# Eval("RightWrong").ToString() %>'/>)
and then access it in code view and write an if statement, but when I try to access the string in codebehind it says it's not available in the current context.

i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)

I have a Formview that allows applications to be inserted into a database. Text boxes such as Name, Address, etc. are bound to the database. I'd like to have the text fields checked for proper case and changed if necessary before writing to the database.
I don't care about notifications, or specialities (such as handling McK..). Looks like the strconv() would work, but I'm not sure how to use it - Still pretty new to using this!

I have a formview, selecting * from friends, where [date] = getdate()
The problem is the friends table date columns datatype is datetime, i cannot make it just date.
I only want to display data if the date is the actual date, i.e. between 00:00:01 and 23:59:59
How do i select only the date for both getdate and my date column?
SelectCommand="SELECT * FROM [friends] WHERE ([date] = getDate())">

i have a FormView, it renders fields from a SQLServer database but also much static text specific to the database value I get. I dont know if this can be done in the code behind and put all this in a function . I put it in my formview
<ItemTemplate>
<% If Eval("Feature1") = "Yes" Then %>
<%# Eval("Username") %> A lot of text
<% elseIf Eval("Feature1") = "No" Then %>
<%# Eval("Username") %>
A lot of different text
<% End If %>
</ItemTemplate>
If I do the code above I get error message:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Can this be done within the formview?

I have a formview that I am adding and editing items. I need to have a lookup button besides a textbox so I can click the button and show a webgrid listing items with their descriptions. Select one and enter the data in the formview control. I know how to put the data in the formview control with the FormView.FindControl method. But how can I add a lookup? Can I do this with a popup panel? And on the postback update the textbox control?

I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.
[Code]....
txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.

i create a composite control as can be seen in code below, and add this control to webform, assign FormView1 to the HeaderControlName property, Run the page, the system will generate parse error message :
Cannot create an object of type 'System.Web.UI.WebControls.FormView' from its string representation 'FormView1' for the 'HeaderControlName' property. However, if i don't assign FormView1 in design screen and manually (through coding) assign FormView1 to the custom control on init, it works as expected.
custom control
public class CmdTest : CompositeControl
{
public virtual FormView HeaderControlName
{
get
{
object oObject = ViewState["HeaderControlName"];
return (oObject == null) ? null : (FormView)oObject;
}
set
{
ViewState["HeaderControlName"] = value;
}
}
protected override void CreateChildControls(
{
Controls.Clear();
Button xx = new Button();
Controls.Add(xx);
}
}
webpage.aspx (assign FormView1 in design time, it will generate error)
<Utils:CmdTest ID="CmdTest1" runat="server" HeaderControlName="FormView1" />
webpage.aspx (didn't assign FormView1 in ASPX, but assign it on Init Code, it works)
<Utils:CmdTest ID="CmdTest1" runat="server" oninit="CmdTest1_Init" />
Webpage.aspx.cs
protected void BsCmdTest1_Init(object sender, EventArgs e)
{
CmdTest1.HeaderControlName = FormView1;
}

I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.

I have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.

And the code behind:

I know it is recommended to use a using statement with a sqldatareader, but I was wondering if it is necessary when you are setting the datasource of a control to a datasource directly. in some places in my code I do this.
using (SqlDataReader reader = getReader())
{
while (reader.Read())
{
// do stuff with data
}
}
when binding to a control I do this.
ddlCustomer.DataSource = getReader(); // get Reader returns a sqldataReader
ddlCustomer.DataBind();
In the second case, do I need to use a using statement. Do i have to first declare an SqlDataReader in a using statement, then set the DataSource to that object. Seems like more clutter in the code, so i was hoping binding to the SqlDataReader disploses of the SqlDataReader.

I hope I have the right forum =)
Here is the issue.
I have a table:
[URL]
What I would like to do is retrieve the Grade score based on a number that is between the Max and Min for that Job Title.
I presume the sql would be like:
"SELECT [Grade] FROM [NUGGET_Tech_Score] WHERE ([Job_Title] = @Job_Title AND @total BETWEEN [MinScore] and [MaxScore])"
However since I am new at this, I am not sure how to get the grade and show it as a label on my form.
Should I be using a Form View control instead of the SQL statement?

Time for my daily ASP.NET question.
One of my pages shows all of our customer information from a customer table. I want the user to choose whether to see all customer records, or select a specific record from a list. So, my webpage has two radio buttons (show all customers, show specific customer), a listbox (full of customer names), and a formview control. The problem I'm having is getting the formview to update when I change modes via radio buttons or listbox selection (see code below).

I am attempting to insert an items using a basic FormView control.
The FormView has standard entries like:
ItemName
ItemPrice
ItemSize
It also has controls that will be hidden from the user such as:
ItemDateCreated
ItemDatechanged
ItemChangedBy
..These items I am attempting to modify their values before the Insert() takes place, so I have captured the event InsertButton_Click():
protected void InsertButton_Click(object sender, EventArgs e)
{
LinkButton btnInsert = (LinkButton)FormView1.FindControl("InsertButton");
TextBox txtDateAdded = (TextBox)FormView1.FindControl("ItemDateAddedTextBox");
[Code]....
It keeps telling me that the ItemName field is NULL, and throws an error, even though I can plainly see the value is being set in the textbox. Why is this value being thrown as NULL? Do I need to manually create the INSERT statement before I call the Insert()? How would I go about doing that?

Please help to understand this RegEx statement in details. It's supposed to validate filename from ASP.Net FileUpload control to allow only jpeg and gif files. It was designed by somebody else and I do not completely understand it. It works fine in Internet Explorer 7.0 but not in Firefox 3.6.
<asp:RegularExpressionValidator id="FileUpLoadValidator" runat="server"

I'm working in a web application and my page is using a databound formview control. When i first enter the page via my code, I am unable to retreive a value from any of my controls -e.g. when i debug, i see that tbDate.text has no value (see code below). How can I retreive the values from the controls on my page e.g text boxes?
Code:
if (!this.IsPostBack)
{
TextBox tbDate = (TextBox)FormView1.Row.Cells[0].FindControl("txtDate");
