Web Forms :: Accept Textbox Value Even If It's Null?

I have a javascript to validate and avoid null values for my form but there are some textboxes that I need to be 'optional'. I tried erasing the validation for province address and province contact in javascript to make it optional, but the problem is whenever I add the values in the database, an error message appears "Input string was not in a correct format". It's in C# This is my present code wherein the provincial address and provincial contact must only be optional:

Forms Data Controls :: Handling A Null Value In Textbox FormView (on Button Click To Calculate Totals)

Mar 17, 2011

I have a rather large formview that asks for a variety of input values (physical totals vs pos report totals). I have created vb code to calculate the differences and subtotals of various types prior to inserting the data so people can check for entry errors.

Its a closing reconciliation form. Here's the problem: If they forget to enter 0 in a field that doesn't have any totals, a big ugly error message displays. I would like to avoid this. I can tell them until I am blue in the face to remember to enter 0 and not leave any blank fields, but realistically its going to happen and I need to handle it in the programming.

I have been struggling to either default the values to zero to start with, replace a null textbox with 0 before the calculate runs...but I can't get anything to really work. What is the best way to handle this?

Here is the aspx page:

[Code]....

And the code behind page with working "Calculate" as long as fields are not left blank (I took out all the test code that made it not work at all)

[Code]....

Finally, the error message I am getting is the following:

[Code]....

I can't seem to find the right combination of programming to account for the "" string to be 0 so that it will add or subtract values in my calculate. I have my sql table setup with default values of 0 so if a field is left blank it will be entered into the database as 0 and not null. It is really just for my inserting of a reconciliation and the running of Calculate Totals to double check their work prior to inserting into the database.

VS 2005 Passing Textbox Values To SQL (not Null)?

May 7, 2010

Code:
SELECT one, two, three, four FROM tblFixedLine_onenet_callLog WHERE (one LIKE '%' + ISNULL(@one,'') + '%') AND (two LIKE '%' + ISNULL(@two, '') + '%') AND (three LIKE '%' + ISNULL(@three, '') + '%') AND (four LIKE '%' + ISNULL(@four, '') + '%') ORDER BY one, two, three, four
@one, @two, @three and @four are textboxes on my ASP.NET page all of which by default have no value(therefore i assumed NULL).If i test the SQL in the VS2005 SQL Configuration (and put the values in manually) it works but the ASP page returns no results... i assume therefore the Textbox value is "" not Null.

Forms Data Controls :: Listview Toggle Visibility Of A Textbox Based On Data Not Null?

Sep 3, 2010

I want to toggle a Textbox to be visible (true, false) contained within an InsertItemTemplate based on the data being Null/Empty.

It Works in the Item Template since it is calling the "select parameters", but once it is in the "insert parameters" on databinds, I am unable to get this to work.

<%# String.IsNullOrEmpty(Convert.ToString(Eval("qu_8")))?Convert.ToBoolean("false"):Convert.ToBoolean("true") %>

(works in Item Templates, but not in InsertItemTemplate to toggle a textbox to be visible or not visible). I am using C# in code behind.

I have a GridView with the following columns

</FooterTemplate>
<ItemTemplate>
<asp:Label ID="lbl_name" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "t_Name") %>' />

<EditItemTemplate>
<asp:TextBox ID="txt_name" runat="server" Width="100px" Text='<%#DataBinder.Eval(Container.DataItem,"t_Name") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Created By">

{
string t_Name = ((TextBox)(gv_Name.FooterRow.FindControl("txt_Name"))).Text;
// Insert Code
}

But I am getting null in the string t_Name everytime irrespective of what is the current Text of txt_Name.
However I can get the text if I disable the ViewState for the page.

Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?

Dec 6, 2010

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Web Forms :: Session Variable Is Null When It Shouldn´t Be Null?

Mar 18, 2010

I have a problem with a SessionVariable. I will explain what is happening:

1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !

2. In the Page_Load, I later fill a ListBox1 with foldernames.

3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)

The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?

if (Session["LoginByAdmin"] == null)
Response.Redirect("Default.aspx");
break;

DataSource Controls :: Null Option In Qurery Parameters / Using Query With DropDownList And Textbox Controls?

Dec 18, 2010

I have SqlDataSource with a few parameters (code below). If I understand this code correctly if parameter is NULL I should receive all items from the query. It works fine with query editor. But when I try to use this query on my page - with DropDownList and Textbox controls as source of parameters - it doesn't work. I suspect that main reason of problem is value which these controls pass to the query. Instead of NULL this is an empty string. Is it possible to pass NULL value from DropDownList or TextBox to
the SqlDataSource?
