Forms Data Controls :: Reading Hidden Data In Grdiview?

Jul 28, 2010

I have a databound gridview with 3 columns. I enumerate through each row to get values and put into an array. I would like to make column1 NOT visible to the user. but when I set Visible="False", it no longer can retieve that columns value as it enumerates.

Is there a way I can make the first column invisible to the user but still retrieve the values of that column when enumerating?

How To Show Collection Of Data Inside One Row Of The GrdiView

Oct 24, 2010

I have a scenario where I will be showing a Customer data in a GridView. I have a Dictionary collection like this IDictionary<Customer, IList<CustomerOrder>>.

First Question Can I bind this dictionary to the ASP.Net GridView?

Now next question, I want to show following kind of UI i.e. Show multiple CustomerOrders in one row of Customer.

FName LastName OrderNumber MarkOrderCompleted(RadioButton)
ABC DEF 123 Radio Buttons Yes No
345 Radio Buttons Yes No
678 Radio Buttons Yes No
GHI JKL 213 Radio Buttons Yes No
546 Radio Buttons Yes No
768 Radio Buttons Yes No

FName and LastName would be populated from Customer object inside the Dictionary and OrderNumber and MarkOrderCompleted would be populated from CustomerOrders. Below all thre is a submit button, which saves the radion buton status values to the database against the Order.

Reading Int From A Hidden Field In .aspx?

May 24, 2010

I'm struggling to read an int from the hidden field on aspx page.

<input type = "hidden" id = "myIntegerId" name = "integerId" value= "<%: Model.MyObjectId %>" runat = "server" />

The value is definately on the form, I can see it in the debugger and print it with <%: %>

When I read the form values in the controller, instead of an int I recieve a following string: <%: Model.MyObjectId %>

I have tried casting data in the hidden field to string and calling ToString() method on that field, neither has worked.

The data is submitted using the post event.

Forms Data Controls :: Reading And Paging From Datasource?

May 16, 2010

I have a form with several controls. I'm trying to read from database and navigating through single record per page. I'm displaying a single record but not navigating through. My customerID field is the primarykey. But there are gaps btw records (1,2,5,6,10...etc). Some of them were deleted.

myPage.aspx:

<%@ Page Language="VB" Debug="true" CodeFile="customer.aspx.vb" Inherits="customer" %>

<form id="form1" runat="server">
Customer ID: <asp:Label ID="lblCustomerID" runat="server" ></asp:Label> <br />
Customer Name : <asp:Label ID="lblCustomerName" runat="server" ></asp:Label><br />

<asp:Button ID="btnNext" runat="server" Text="Next" OnClick="Next_OnClick"/>

Dim myReader As SqlDataReader
Dim myConnection = New SqlConnection("server=myPCSQLEXPRESS; database=CustomersDB; uid=myPC est; Password=; Trusted_Connection=yes")
myConnection.Open()
Dim myCommand = New SqlCommand("SELECT * FROM Customers", myConnection)
Dim intFirstRecord As Integer = CInt(myCommand.ExecuteScalar())
myReader = myCommand.ExecuteReader()
If myReader.Read Then
lblCustomerID.Text = myReader("customerID")
lblCustomerName.Text = myReader("CustomerName")
End If
myReader.Close()
myConnection.Close()
currentRecord = lblCustomerID.Text
End Sub

Sub Next_OnClick(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myCommand As SqlCommand
Dim myConnection As SqlConnection
Dim myReader As SqlDataReader
myConnection = New SqlConnection("server=myPCSQLEXPRESS; database=CustomersDB; uid=myPC est; Password=; Trusted_Connection=yes")
myConnection.Open()
myCommand = New SqlCommand("SELECT TOP 1 customerID, CustomerName FROM Customers WHERE customerID > @customerID", myConnection)
myCommand.Parameters.Add("@customerID", SqlDbType.Int, 5).Value = currentRecord
myReader = myCommand.ExecuteReader()

If myReader.Read Then
lblCustomerID.Text = myReader("customerID")
lblCustomerName.Text = myReader("CustomerName")
End If
myReader.Close()
myConnection.Close()
End Sub

I'm being able to read first record. If I click Next button, my page goes to next record for only once. If i click several times, nothing happens. Does not go to next available records.

Forms Data Controls :: Reading A GridView Which Has Text Boxes?

Jan 12, 2010

have created a gridview with input text boxes inside which can be added by the user.

So in order to populate the gridview on form load I use grdView.DataSource = PopulateDT(); this.grdView.DataBind();

Now is there a neat way of retriving the data content after the user has entered data from the gridview and store as a datatable. The only way is doing a for next loop which i think its time wasting.

Forms Data Controls :: Grid View - Can't Get The Value Of An Hidden Field's Footer Row

Dec 3, 2010

I can't get this to work:

I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.

[Code]....

While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read

[Code]....

so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.

[Code]....

so, while debugging, lblImp.Text = "";

why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.

Forms Data Controls :: Hidden Cells Become Visible When PageIndexChanging Fired?

Oct 7, 2010

I am having an issue with hidden cells when a PageIndexChanging event is fired in a gridview.

On the page_load I am setting the visibility of an edit button in a cell of a gridview to true or false depending on a users credentials.

Everything works as intended when the page is first loaded. When I click to a different page index the edit button is visible in all cells when it shouldn't be. The edit button is then visible in all cells even if I navigate back to the first page.

Here is the pageindexchanging event:

protected void GridView_EmployeeList_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView_EmployeeList.PageIndex = e.NewPageIndex;
GridView_EmployeeList.DataBind();
}

Here is some code from the page_load:

protected void Page_Load(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView_EmployeeList.Rows)
{
If(row.Cells[1] == "Manager")
{
row.Cells[13].Visible = true;
}
else
{
row.Cells[13].Visible = false;
}
}
}

Forms Data Controls :: Collections Versus Reading Database Every-time

Jan 18, 2010

1. I know about collections but I dont remember the precess. I know you drag a sqldatasource control on the form(Select everything in the database ie. selct *) and then delete it. But how do I use it i code.

Example. I need to select services where country=canada from the Agencies table.

2. I know how to manually pull data from an access database using the code below. I want to know how to pull data from a sql database just like the one below.

3. explain the difference between Collections and manually pulling it like the one bellow?

<code>
<script>
Stringpath = Server.Mappath = Server. MapPath(/website");
String connStr = Provider=Microsoft.Jet.OLEDB.4.0" +"DataSource="+path+
\Database;

Forms Data Controls :: Escape Apostrophe When Binding To Hidden Field In Gridview?

Apr 15, 2010

I've got a gridview with a hidden field, i'm trying to set a value as follows:

value='<%# DataBinder.Eval(Container.DataItem, "Name")%>'

which works in most cases except when the name has an apostrophe like O'Neil. I need to escape the ' if possible.

so i tried: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " /' ")%>' and

value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " //' ")%>'

which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.

This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '

Forms Data Controls :: Listview Not Reading Info From Databound Items On Update

Mar 14, 2011

have an annoying problem. i'm trying to update single items in a databound listview. but when i click the update button it gives me the cannot insert NULL value. it doesnt seem to read anything from the textboxes which i have databound from the database. even though text is clearly shown...

i have setup my update statement and parameters, it uses the Update command name and ItemUpdating event. i catch the data from the textboxes by using e.ItemIndex and use the text assigned to the parameters in a SqlCommand.

The thing i'm aiming for too is that when an item is updated it stays on the page where the item was updated, (i was using response.redirect before but it went against my aim since the whole page reloaded)

Forms Data Controls :: Page Set Up - When A User Clicks On A Row In The Gridview A Hidden Checkbox Is Unchecked

Jun 8, 2010

i am trying to do is set my page up so that when a user clicks on a row in the gridview a hidden checkbox is unchecked... i am new to asp.net but never thought something as simple like this could be so difficult to work out... i've been on it for around 5 weeks now, i started this on my first day of the website, and have actually designed and written the entire site while still trying to work this out... i first did this on the selectedindexchanged event:

Dim cbox As CheckBox = CType(GridView1.Rows(GridView1.SelectedIndex).FindControl("CheckBox1"), CheckBox)

If cbox IsNot Nothing Then

If cbox.Checked = True Then[code]....

problem is the above code throws up errors...! once i take out the where clause it unchecks every checkbox and writes it back... is there a way i can say just uncheck the selectedrow checkbox and update that one row???

i'll admit there are better ways of doing this, and i'm sure the above code is a little messy,

DataSource Controls :: Reading Data From An SQL Query C#?

Feb 26, 2010

I don't know how to read data into variables from a SELECT query. I can add, update, and delete queries with no issues. I have browsed a few books, but everyone uses a different approach. Suppose I want to to run a query and 1 record is returned. How do I get the values into my variables.

Suppose my table name is "Job Orders", and the row returned has these 3 fields:

JobNumber, FirstName, Lastname

[Code]....

[Code]....

this is where I go blank ?
