Im learning to use a gridview and a problem that im seeing is that putting an edit command in the gridview so that I can update a particular row. When I click the edit, it turns to the update as expected, I hit the update and the particular field turns the row into editable textboxes which is expected. The problem that I notice is that if I click another row, I get this error:

I have programmed gridview, where you Edit a row and then update it using link buttons provided on the row.But when a user has to make couple of edits on the same grid, it should be saved with one button click and one refresh to reflect updated data.
View 3 RepliesI have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?
View 1 RepliesI am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.

I am having trouble with a separate program that keeps saying Adobe flash is not installed. And I have tried everything but it still wont go away (that was off topic a bit).

View 4 RepliesI have a list of items in a GridView, with one column I'd like editable through a DropDownList.
I do not wish to put the GridView into 'edit' mode or have any 'confirm/update/save' buttons.. I just want autopostback on the DDL, and an OnSelectedIndexChangedevent to update the row.
Problem is, from my OnSelectedIndexChangedevent within the DDL, although I can see the new value to save, I can't discover the row to update from the GridView.
how I can achieve what I wish? Other than perhaps storing the row id within the DDL? Maybe turn it around so the GridView's events are called?
I am trying to get a parameter for my update from the gridview but it is an ID column that I do not want displayed. If I display the data in a boundfield it works fine but if I set the visibility to false the parameter is no longer sent to the update stored procedure. There does not appear to be a hiddenfield column that I can put into the gridview.I have tried to set the parameters through the code behind but I am not certain on how to access the data I want the following code does not work (It sets the parameter to nothing

I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.
SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1
FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName
[Code]....
It basically calculates the total number of approved holiday requests for a staff member which is correct. I want this number to then update the HolidayTaken field in another table each time a holiday is approved.
I have tried an update however you cannot use an aggregate in an update as I have found.
I have asked a question similar to this in the past. I was able to resolve it by removing gvRowDataBound completely from the code. This is similar code except I can't remove gvRowDataBound sub.
The issue is that when you click the Edit button of the first row, it allows you to successfully update that row.After the first row, if you click on thr edit button of any other row, enter the value to update, it doesn't update that row.
Instead, the cursor moves down to the next row. I didn't design this and having difficulty figuring out what needs to change.

I've got a gridview (ASP.net) inside of an update panel. I also have a "Save" button so that when I click "Save" it loops through all the rows of a grid view and passes the data to a stored procedure to update each row. This was too slow as sometimes I would be updating the database even though a change did not occur.
I decided to add a field in my gridview like so:
<asp:TemplateField>
<ItemTemplate>
<input type="hidden" id="hdnIsChanged" runat="server" />

Apparently, part of the problem is that while an ASP:GridView has an OnDataBound() event (which you can use in the code-behind), the corresponding HTML table that is produced does NOT, so you can attach that event to JavaScript. (Did I get that right?) So, that's why I'm having trouble with that bit of the issue. Back to the drawing board. I'm a desktop developer (WinForms with VB.NET) transitioning into ASP.NET development. My mind is really bending around the DOM and JavaScript and Session State and all of the stuff that goes along with web development. I'm not stupid, and I've done research (including hours of video watching and hundreds of pages of "Intro to ASP.NET" reading), but I keep hitting the wall with what seem to be fairly straightforward problems.
Basically, my current situation can be summed up as follows:
I have a page that runs a very long process initiated by the user. The long process can take up to a few minutes , so I want to indicate to the user that SOMETHING is happening.When the process has completed, I either have:
a. Results to show in a GridView
b. No results to show
If I have results to show, I want to display them. If I have no results to show, I want to show a label to the user that says "No results to show."

View 1 RepliesI'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.

I am working on an aspx site that lets an admin-level user fill out a form with potential member data. Once the form is filled out, the user will click submit and the data will go off to different tables. One part of the form that is stumping me involves filling out three textboxes (txtFirstName, txtLastName, txtGrade). I have a button (btnAddStudent), that, when clicked, should add the information from the textboxes to a table-like display area. I am trying to use a gridview, but there is nothing to bind it to. There is no memberID number to load a blank record from the Student table (which is a many-to-one relation to Member table). The member record is what this form is creating, and the student data will be added to the Student table when the Submit button is clicked.
I am currently working with the code found in the reply here. But when I click the "Add Student" button, I get a new blank row, but my textbox values are not inputted in the gridview.
Can this work, or do I need to look at using a table and adding rows of textboxes dynamically?
Here is relevant source code:

View 4 RepliesI have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.
I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB
