View 2 RepliesI 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.
I have two columns in my Gridview marked false for the visible property but which are clearly listed in the DataKeyNames that are still getting set to null in my database table on update.
The first one is a column MId# which is a type int. It starts as 0 but on edit is turned into null. The Second is RequireSKU which is also converted to null.
I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?

Initially, I wrote the GetTeamMember() method to display the FullName in the ItemTemplate.
Then as I wrote the EditTemplate, I needed to populate a DropDownList with a list of names (first and last). It was fairly easy using the LinqDataSource, however it currently only shows the LastName. I could write another method GetTeamMembers() to populate the ddlTeamMember with the data I want, but I thought maybe there's a better "LINQ" way.
So I'm looking for a better way to get FullName (i.e. Firstname + " " + LastName) into both lblTeamMember and ddlTeamMember.
Options I thought of are:
I could write a method GetTeamMembers() I write a StoredProc that returns the extra column Better way?
I have a dataset.table which has some null values. am trying to trasform this using xslt to display like excel. If the value is null, then that node is ommitted by the xml. i tried deafulting the null values from the database itself and thats not generic. Handling null values is troublesome. I tried couple of methods to default null values by looping and thats not optimal solution. I used LINQ to handle null values but couldnt comeup with a neat solution. what am looking for is a generic optimal solution to handle these values.

Basically, the user Selects a row on GV that executes an Insert into a table the GV cell values of the selected row.
The SQL field data type is varchar. If the GV field is Null, the Insert adds the value to the SQL field. How do I keep the @nbsp; from being displayed in the cell of a data control when it is called at a later time? Do I add some more asp to my control parameter? do I add some vb code behind? Here are some relevant code snippets of existing code.

I have developed my application using ASP.NET with Visual Basic. I have a table that contains 3 fields. The name of the table is "Customer" and the names of the fields are "Name", "Address", and "Amount". I have a gridview that displays these three columns. I want to summarize the value in the "Amount" column for each record and display the summarize value in the footer of the "Amount" column.
I added some code to the "ItemTemplate" and "FooterTemplate" of the template for the "Amount" field and wrote two functions One function adds the value of the "Amount" field to a variable called "TotalAmount" and the second function 'gets' the value stored in the "TotalAmount" variable.
I am not getting any error messages and all of the items are displayed in the gridview but I am not displaying anything at the bottom of the "Amount" column. What more do I need to do?
This is my code for the "Amount" template:
<asp:TemplateField
HeaderText="Amount"
SortExpression="Amount">
<EditItemTemplate>
<asp:TextBox
ID="TextBox1"
runat="server"
Text='<%# Bind("Amount") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label
ID="Label1"
runat="server"
Text='<%# Bind("Amount", "{0:c}") %>'>
<%#SumAmount(Eval("Amount")) %></asp:Label>
</ItemTemplate>
<FooterTemplate>
<%#GetTotalAmount() %></FooterTemplate>
<FooterStyle
BorderColor="Black"
BorderStyle="Solid"
/>
</asp:TemplateField>
This is the code in my .vp file
Dim TotalAmount as decimal 0.0
Function SumAmount(ByVal Amount
As
Decimal)
As
Decimal
TotalAmount = TotalAmount + TotalAmount
End
Function
Function GetTotalAmount()
As
Decimal
Return TotalAmount
End
Function
I have a datagrid which displays a list of user data, such as name, his or her status, age. I have created a list of rows of user data but where the column shows status for example Single, Married, i want it to create a dropdown list where i can easily change the user status by selecting it from a dropdown and clicking the update button at the top of the datagrid. The update button will update all records that have been changed not just from the dropdown. I assume the dropdownlist requires a columnbinding event but i can't find any straight forward tutorials.

View 1 RepliesI've been reading up on SQL Injection and want to go back and implement some measures to prevent these kinds of potential attacks.For example, on our company intranet, we have an address book feature and a search function so the user is able to look a company or a person up from the database/The user will enter their query into a TextBox control and click the Submit button, calling the following function:addybookDS1.SelectCommand = "SELECT * FROM [addressbook] WHERE COMPANY LIKE '%" + search1 + "%' OR CONTACT LIKE '%" + search1 + "%' OR LASTNAME LIKE '%" + search1 + "%' OR EMAIL LIKE '%" + search1 + "%'"search1 is the TextBox controlI had previously implemented this measure:search1 = Replace(search1, "'", "''")But I want to know if there is more I can do here and how I can go about doing it.

I have a GridView bound to a DataTable that I construct. Most columns in the table contain the raw HTML for a hypelinklink, and I would like that HTML to render as a link in the browser, but the GridView is automatically encoding the HTML, so it renders as markup.
How can I avoid this without explicitly adding HyperLink, or any other, columns?
