Add A FooterRow To A Gridview Which Has No Value Initially?
Apr 17, 2009
datasource to gridview.I have to populate gridview by adding footerrow.I have given visibility of footerrow as true.So one error is coming as 'Object not set to an instance of an object'.what may be the reason for this?Actually i need to add data into the Gridview through the FooterRow.After inserting a few records,i need to insert this data into the database.So, i want this Gridview only to insert data into the database.For a particular "FileID", i have many records,thats why i am using Gridview.Is there any other method for this?

I have a GridView and, using a fairly common method, I'm using a FooterRow and TemplateFields to provide the missing insert ability. So far so good.The footer contains a TemplateField with a LinkButton to provide the postback that does the insertion. In the handler for the LinkButton's click, the Insert() method is called on the ObjectDataSource that the GridView is bound to. The ObjectDataSource's insert parameters are populated in the handler for its Inserting event. The code for all of this (abridged) looks like this:
Markup:
<asp:GridView ID="gvComplexRates" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="odsComplexMileageRates"
EnableModelValidation="True" ShowFooter="True">
<Columns>
[code]....
The first of these shows a tag of td. Which makes sense. The second shows text of "10" which is the content for the row above the footer.

I am totally new to VB2008, so please bear with this likely dumb question.
I have seen numerous "my first program" tutorial that show you how to create your form, put controls on it, etc. I can get through those just fine.
However, I am wondering: If I compile a set of subroutines into a .exe, how do I indicate which code/sub to execute initially? I am an old school programmer (remember COBOL?), and we always had a starting point; a set of code execute, that initiated execution of other subroutines, functions, etc.
I have dabbled in VBA for Excel, and MS Access, and even those, you indicate in the interface, and menus you create, that first bit of code that brings up the menu, or perhaps the program's main interface.

Okay I have everything working as it should but when I first start up the data doesn't show up in the datagridview until I enter another record. It seems to be at the End Sub part of the button click Enter Record.This is what I have at form load event.

How do you declare an array when the array is initially empty?? I am taking multiple measurements from a meter that I want to put into an array. How would I declare that?? Here is my code to accept the last measured value.
HTML
Dim measResult as string
For I as Integer = 1 to 4
measResult = objDevice.gpibRead(i, 30) ''30 is the buffer size
Next
How can I set up measResult so it is an array that will hold all of the measurements from the meter?? I have tried Dim measResult() as string, Dim measResult() as String = objDevice.gpibRead(1, 30) but no luck.

The code below is used to check if the application setting, an arraylist is populated or not via the count method.
When running the program fails with error "NullReferenceException was unhandled" as initially the setting (arraylist) will contain no values.In similar circumstances I would declare a new instance of the object or set value to string.empty or check if DBNull.
I know application settings have a save method but to reference/load them one is not needed.I also left the value field in the projects -> settings to be empty.[code]...

I am working with a datagridview. Is there any chance a column is set to be a textbox initially but for example I want the top item to be a combobox??? This should enabled the user to select something of the list but also load in what was selected and saved before... So for example I have a column called Product Name and it has 5 rows 4 of them should appear as textboxes but one top cell should appear as combobox

I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

EDIT: forgot to mention, so better state this before anything else... I'm running VS 2005 with Framework 2.0.I have a GridView (gdvN) with 7 columns (N1, N2, N3, N4, Edit command e um Delete command). In the same aspx, 4 textbox (that would be a new line with new N1, N2, N3 and N4 values.).
After filling the textboxes and pressing a button, it was supposed to insert a Row in the gdvN.
[Code]...
Unfortunately that didn't solved, as it edits an existing row instead of adding one. As I can see, that may be two paths for this to be solved:Is there a way to make _newitem be created with the same structure as the gdvN rows. I didn't found how.Or there's another logic (or a mistake in the coding) I'm not looking?

I have a gridview in which I have set datasource as a datatable. Whatever update I make to the gridview, it should reflect only in the datatable and not to the database. When I click update, I have to get the row number of a particular row which I want to update. How can I get the row number in rowupdating event of gridview in order to update the datatable? Suppose I have a datakey and if I get that unique id, how can I update the datatable which is the datasource?

The gridview on my page is set up with templat fields in each column so that I can enter information and save it to my database. There is no data that ties directly into the gridview just the ability to add multiple rows at a time to save the data. I had it displayed with empty textboxes and it was working fine and all of a it stopped and now won't show up. Any clues as to what is happening. Code follows...
