Asp.net - Dynamic GridView Has 0 Rows On RowCommand

May 14, 2009

I have a dynamically-created GridView which to which I'm attaching a handler using the AddHandler command. The problem is that when I try to refer to sender.rows within that function, it won't do anything because it says that sender.rows.count = 0. I've done enough dynamic form creation that I'm pretty sure that I'm creating the controls, binding them, and adding the handler at the proper points during the page init/load load_complete. Also, I have nearly the exact same code-behind on another form that is not dynamic, and it is able to access the values in the rows.

Considering that the RowCommand event is firing, it's clear that I'm clicking on a row. For some reason it's just not in scope for the handler event. Background: What I really want to do is access the values that are databound to the row. I'm creating a SQLCommand and binding that to the dynamic grid, and I would prefer to talk to the grid's datasource, but that doesn't seem to be possible. Perhaps I'm missing something, but for now it seems that reading the values from the GridView (which I hate doing) is the only thing that works.

Update Event Isn't Fired In A Dynamic Gridview?

Feb 20, 2012

I'm creating a dynamic gridview in vb.net using a connected sql database. Everything works fine except 1 thing: when i click the update command, the event just won't fire no matter what I do. the gridview goes into edit mode and the cancel button works fine. This has cost me over 2 days of googling but none of the solutions work. I used breakpoints to check if the code was executed, but it wasn't. If anybody has any experience in this:I believe the problem lies in the addhandler but it doesn't give any errors.I forgot to mention that the sql command was a test and sets the data in that field to 15, now it's 10, it works when i use a normal button or a static gridview.

Dynamic GridView - Insure The Input For The Textboxes Is An Integer

Dec 17, 2009

I have a web page with 5 checkboxes and 2 textboxes per checkbox. When the user checks one or more checkboxes the corresponding textboxes become enalbed for UI. I need to insure that the input for the textboxes is an integer-that I will do with a validators. There is a gridView on the same page. When the user checks one or more checkboxes the 2 columns of the gridView rows become active for input through enabled textboxes.

There are 4 columns in the grid. The minimum number of rows enabled are 2 and the maximum are 26. The UI for the grid's textbox input is numbers. Those numbers have to be equal to or less than the total. How do I validate UI of numbers(integers) into the grid's dynamically generated textboxes and then add the total and compare it to the alloted total? I prefer to do this with the code behind - using VB.NET - rather than with ASP.NET or absolutely not javascript.

Retain Field Values On Error In A Dynamic Gridview?

I have a page which has a GridView on it, which is populated from a database. Some of the columns in the GridView have text boxes, as well as Checkboxes.When the user saves the page, the page may error if they have not entered their data correctly. At this point, I need to re-display what they have entered already so they can simply make the correction instead of having to change everything from scratch again.

VS 2008 - How To Add Dynamic Timers To Form On Runtime

Jan 1, 2010

I am working with a simple game idea. I wanted to have two players running around shooting each other (very low graphics, like circles and squares). I've got this far; I have the ability to move around both characters, and change directions etc. ive also been able to set up my shooting. Only problem I run into is getting the bullet to move! I cant use a preset timer, because if I used that, I could only shoot one bullet at a time, so I would need to create new ones dynamically.

So my question is; how does one add dynamic timers to a form on runtime, and alter the tick sub so that it moves the picturebox (bullet) and once it can be moved, (I was thinking about using player locations in relation to the bullet, and if they were equal than the health would go down or whatever, but unfortunately, this means it would have to be directly in the middle of the player, which would be odd..

C# - ASPX Page (vb.net) With Dynamic Controls Created At Runtime?

Jun 14, 2011

I have a nested content page within a master page, upon load the the page retrieves from a SQL a list of controls to create (Field Type, FieldName) i.e. String, Username.The function loops around the list creating the controls on the webform in a Placeholder, this part works perfectly. The problem that I am experiencing is the request to obtain the value entered by the user in the dynamically created control, I need to perform this call following postback/callback.

If I take the Content page and make it a standard aspx page with no master page the application works fine. Unfortunatley taking the page out of the master page is not an option (unfortunatley a restriction by my client)

Dynamically Select Table At Runtime With Dynamic LINQ?

Feb 17, 2011

I'm developing an application to allow engineers to conduct simple single table/view queries against our databases by selecting Database, Table, Fields.

I get how to use the Dynamic LINQ Library Sample to provide for dynamically selecting the Select, Where and Order by Clauses at runtime but I'm at an impass on how to allot for table choice.

Is there a way to provide for dynamically selecting the "from" table at run time

EDIT

So Both of the answers seem to be saying the same general Idea. I'm going to try to convert the C# into VB and get it to work.

The first answer converts to

Enter Values / Elements Into Dynamic Array During Runtime

Sep 4, 2010

I am new in programming. And I am coding with VB.Net (VB2008). On my form I have 9 checkboxes. And each of this checkbox when checked is meant to submit a value to a dynamic array. Initially the array was a constant that was declared like these:
Dim Notes() AS integer = {1, 2, 5, 10, 20, 50, 100, 200, 500, 1000}

But I want the array to be dynamic. That is the user of the program is to enter the element of the array. So I decided to use checkboxes. So that if the user of the program checks any of the checkboxes, a particular value or element should be submitted into the array. And the user should be able to check as many checkboxes and have values representing those checkboxes submitted in to the array.

For example: if the user check checkbox1, checkbox2 and checkbox50.
The array should look like these. { 1, 2, 50 }
or if the user check checkbox1000, checkbox200, checkbox10 and checkbox500
Then the array should hold or contain the following integers in this order; {20, 200, 500, 1000}.

That is the array is dynamic and the content/elements of the array and the bound of the array should depend on the checkboxes that is checked. What other means can I used to enter values/elements into a dynamic array during run time.

Format Gridview As Date/Time At Runtime In VB Code?

Feb 18, 2009

I am putting together a kind of "build your own report" page that will have up to 20 options for people to select.Each option, selected by checkbox or dropdown (probably) will add on to the SQL data source to pull only the information needed and display it in a gridview.For instance, the initial query is:

Select
C.Name,
From Clients as C

[code].....

How can I do this, preferably referring to the column using the column name of "My Position" and not a numeric...If this can NOT be done....The other option is to query everything and format it - and then hide columns in the gridview based on items that are not checked. Would this be easier? (Doesn't sound as efficient to me).
