I have a problem with a GridView control.I am using the UpdateCommand but the new value is not being stored. If I hard-code in the value to the aspx page it works fine but not if I pass the parameter.The value I am trying to update is called "PC_NAME" an it is an integer.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" ForeColor="#990000"
AutoGenerateEditButton="True" onrowupdated="GridView1_RowUpdated"
onselectedindexchanged="GridView1_SelectedIndexChanged"
AllowSorting="True">

How specify input parameters to UpdateCommand
View 3 RepliesI'd like to pull several NewValues from a FormView and write them to a database as part of the Update command.For some reason, I am unable to do this using the following code. Is there something I am missing?

Using the code below, I am able to load my dynamic dropdownlist and supply it's selectedindex. But when I fire the update command I can see that the information displayed has been lost.

i have a grid in which i did this :
i get into console it is giving this error on update click :
Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Updating is not supported by data source 'ExistingSqlSource' unless UpdateCommand is specified.
I'm trying to understand how to get the UpdateCommand to work with an Access DataSource and a GridView controlI can click Edit which opens the row for editing, change the Department Field, then click the Update link. The page refreshes, but the change I made is not updated. I have tried hard coding the UniqueID field with a '1' and hardcoding a new Department code into my code and that works. But I really need the interaction with the user version to work. This is my first attempt to use VS 2008 with a web page.

I used asp.net server side control to display and modify data in database, the control is just like this one:[URL]what I want to do is after I click the "edit" button it will display a "edit" ui, and I want everytime I modify the data in the text box, asp.net will automatically click the "update" button for me to update the data i entered.
I tried to call the event handler, but failed.
There is a update command in asp.net, and how to programmatically call it ?
I have two gridviews, say 'A' and 'B'...I want to add all the rows of 'A' to 'B' while avoiding the duplicates....For eg:
View 10 RepliesIn nested gridview, i am finding some problem, i want to show child Grid headers in Parent Gridview. Can anyone tell me that how it is possible? Its very urgent. Waiting for quick response.
View 1 RepliesFrom my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...

I had a problem with my site in the past couple days and have almost recovered, but now I'm stuck on some code that has an Auto-Complete feature, which allows a user to type a name of a pub into a TetxBox, and based on the returned names, the user can click one and see that name in the GridView (just below the TextBox). The GridView was set up so that there was an href that the user could click on and that would open a window and the user would see the pub in Google Maps. The code below works just fine for the Auto-Complete and the GridView.

Here is the end of the working code. Somehow I need to use the code below to make

The code above worked fine before, but I'm not sure how it was incorporated into the GridView, and since I had a problem with my site a few days ago, I haven't been able to figure out this part.I'd sincerely appreciate any help in getting this up and running again.
I currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn
1 1111 2222 3333 Yes / No (selected Yes)
2 2222 3333 4444 Yes / No
GRIDVIEW2
ID NotesColumn
1 Texbox displays here
