Forms Data Controls :: Making Checkbox Check If Values Are Not Null?
Feb 28, 2011
I have a Sql Data Source that queries my class database. What I'm trying to do to save myself some landscape is to check a checkbox if any of the pre-requisite fields are not empty. I have this laying inside a gridview. My code doesn't error out but it doesnt' do anything either.
[Code]....
My query is like this:
[Code]....
So in a nutshell, if there is any value in PR1 - PR7, I want to check my checkbox in the gridview.

I have gridviwe having 2 columns:
1) DocNumber 2)Title
query select docnumber,title from tbl_docs.
BindwithGridviwe(sql);
Now the issue is that that every document doesn't has document number. I want to make invisible the docuNumber column of the grid viwe if all values in the docNumber retrieved are null.for example:
docnumber tite
null Document 1
null Document 2
null doucment 3
null document 4
if returned result match above where all docnumber are null then make the gridviwe docnumber column ivisible eslemake the greidviwe column visible.

I have the following code
public class ProductDetails
{
private string _productid;
public string ProductID
{
get { return _productid; }
}
private string _description;
public string Description
{
get { return _description; }
}
private string _image;
public string Image
{
get { return _image; }
}
public ProductDetails(string productid, string description, string image)
{
_productid = productid;
_description = description;
_image = image;
}
}
public class DataAccess
{
private static string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
public ProductDetails GetProductDetails()
{
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd = new SqlCommand("ProductDetails", con);
cmd.CommandType = CommandType.StoredProcedure;
string productid = HttpContext.Current.Request.QueryString["productid"];
cmd.Parameters.Add(new SqlParameter("productid", SqlDbType.NVarChar)).Value = productid;
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
reader.Read();
ProductDetails pro = new ProductDetails(
(string)reader["ProductID"], (string)reader["Description"], (string)reader["Image"]);
reader.Close();
return pro;
}
}
protected void PopulateControls()
private DataAccess da = new DataAccess();
{
ProductDetails product = da.GetProductDetails();
if (product.Description == String.Empty)
{
lblDescription.Visible = false;
}
else
{
lblDescription.Text = product.Description;
}
}
In the last piece i want to check if the Description field is null or empty in order to hide the label control but i get an error if i write: if (product.Description == DBNull.Value) and can only use ring.Empty. But i want to check for NULL values as well..

I have a datagrid which is bound to a stored procedure in the code behind. This works fine. But the datagrid contains a checkbox which I need to be default checked. First I didn't bind the checkbox and just used:
<ItemTemplate> <asp:CheckBox ID="chkSelection" Runat="server" Checked= "true" /> </ItemTemplate>
but they show as unchecked. then bound it using:
<ItemTemplate>

I have a field "Active" which can contain either 1 or 0. In the aspx form, I am displaying it in a checkbox in gridview. If the database value is 1, I should have the checkbox as checked, otherwise it should be unchecked. How can this be done.

I have a gridview that contains check box in first column for each row. I also have a check box outside the grid view called >>>>
<asp:CheckBox ID="chkSelectAll" runat="server" Text="Select All" AutoPostBack="true"
OnCheckedChanged="chkSelectAll_CheckedChanged" />
I either can select more than one checkboxes from gridview then click on a button to get the number of checkboxes selected OR I click on SelectAll checkbox ( which is outside the gridview ) which check all the checkboxes in the gridview and give me the number of checkedboxes. When I select inidividual checkboxes inside the gridview, th e count of number of checkboxes is correct ( displayed in a lable ) However;
When I click "SelectAll" check box, it give me total of all checkboxes chekced in the
gridview + 1 ( extra ) I am trying to get rid of this extra one by checking if this "Allcheckbox" is selected to so I subtract one from the total count .. like this
// java code ... code not shown does capture the total count into c variable
varAllChecked = document.getElementById('chkSelectAll');
if (varAllChecked.checked== true)
litCount.innerText = c - 1;
else
litCount.innerText = c;

I've got a details view control on a page. One of the columns, from the database table, is a bit field. It is not nullable, and that's the way it has to be. Also, in most cases, when inserting data, it will be true (1) be default. I've found in testing, when inserting data, that it was false, for some reason. So, I changed the column to a template field and went to the InsertItemTemplate for that column, and changed the checkbox Checked property to True, instead of the default False. However, it has really screwed up the page because now it won't save anything at all! When I try saving something using the details view, it does show the checkbox as being checked, but man, once I try saving it I get an error message back from the database saying that the column doesn't allow for nulls.
Huh??? How in heck can the column on the page have a value (it is checked), but when it goes to save something it fails? Furthermore, before I converted this field to a template field, it worked perfectly. I tested several other insertions, and they all worked. But when I converted it to a template field, it stopped working? What's that about? I even tried setting the default value for the Checked property of the checkbox back to False, but that still doesn't work, it still wants to pass in a null. What's going on here? Why is it that converting a field to a template field, which was working perfectly fine before I made the convension, stop it from working at all?

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

have a form where I insert record via DetailView control. I have some string fields. For each string field (nvarchar in sql) I have defined the Default Value in the SQL SERVER (2008) as ''. Also I have added to each InsertParameter of the DetailsView a DefaultValue="".Yet still, if the user enters no value for one of the string fields, NULL is inserted into the table.
