Forms Data Controls :: Replace Figures With Null In Gridview?

Nov 9, 2010

i have a grid view that displays a load of figures, and as there is a lot of zero's in these tables i wondered if it would be possible to just display nothing were there is a "0" ... just to make it look cleaner?

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.

Forms Data Controls :: Failed To Load Viewstate When Gridview Control - Replace Gridview With Datagrid

Apr 5, 2010

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.

I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

Forms Data Controls :: How To Replace Data That Is In Details View, Details View Will Not Save Empty/null Value

Apr 28, 2010

I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.

Forms Data Controls :: CheckBox In GridView - Replace With Images?

Jun 15, 2010

I am relatively new to asp.net and program using VB. I have written the following code to try and replace ReadOnly CheckBoxes with an image as the CheckBoxes appear grayed out and difficult to see. The GridView is linked to a SQL DataSource to display information only.

The problem I am having is displaying the image for unchecked boxes where the data (PET) in the SQL table is set to 'false'. The code displays the checkbox image fine when the bit is set to 'true', but no image appears in the GridView rows where the bit is 'false'.

Forms Data Controls :: Null Fields After Update In Gridview?

Apr 13, 2010

I have a Gridview showing the data on one of my tables, and when I try to edit the data in one of the columns after I click update, rather than updating the record with the new value I typed in, the rows become null as in, everything in the row I just edited disappears. This inmediatly makes my application crash because one of the fields in my table (IssueDescription) doesn't allows null values.

This is the code, which is actually 100% auto-generated from when I created the GridView control and specified in the options to implement update, delete, edit options.

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="ticketNum"
DataSourceID="SqlDataSource1" [code].....

What is making the rows turn into null after the update? I did some research and tried to define the Update behaviour myself using RowUpdating function. After hours of learning how to use it I got it to "work", but because the Update turns everything to null when it updates, the sqlconnection command I use to do the query sends null anyways. I can paste the C# code if you'd like to see it, though I'd rather not use it if the auto-generated by asp above can be fixed instead.

Forms Data Controls :: Gridview Non-visible Values Always Go To Null?

Jun 24, 2010

Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?
