I just spent the last week and a half working on a gridview for a user and now he says he wants it so that all the records are updatable! He doesn't want to click on the Edit button, he just wants everything open for update. Is this possible? Or would anther control do it?

i couldnt find a specific answer to this question, i am relatively new to .net :)
i have a gridview that is displaying data from a sqldatasource in my page_load event. i need to loop through the records and update each value of a particular column BEFORE being set into the GridView.
i have tried converting to a data set and looping through updating the values, however it seems that one i initially run my query the values get set right into the GridView and i can't update them after that.
Do I need to add one of the GridView functions like Databound and do the loop in there?

I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
Iam using the Gridview control for inserting the records in Database i placed the controls in TemplateField tag like Textboxes and DropDownlist but when page executes nothing is displaying in the control Is there any way to get it work or i must have to define the datasource for the Gridview Control????
<asp:TemplateField ...>
<ItemTemplate>
<asp:DropDownList ..../>
And more textboxes like the above way but there is no Bound Field because iam going to insert the record in DB while placing the controls in Gridview Control
I was wondering if there is any way to view an sql statement that is created by a templateField Gridview when updating? I had my Gridview working properly then I changed my update statement to update less fields and I changed a couple more things on the page and now I don't know what broke it. The error I'm getting is
"System.Data.OleDb.OleDbException: Syntax error in UPDATE statement."
When I searched for this error it said to debug it but all that happens when I do that is visual studio tells me there were errors because it couldn't find my header, which it does find when it runs regularly so this isn't the problem.
I made a project to use the access membership provider from http://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=404 and it works. But I need to edit my database but when I configure my database, I cannot see the tabel, I can only see the queries in mdb file. when I select the field from query, I am unable to update it. My code is as follows and I hope it is clear. thanks a lot.

View 1 RepliesI have 4 file uploader in my form to upload 4 images in the DB for each article submitted. My issue when I want update/edit my article with some new pictures and I want delete or update the old pictures with the replacement with the new one.
How I can implement it? I am using ASP.NET based on VB.NOT .... NOT C#
I was wondering if there is a built-in way (or other) to use images to act as page controls for Prev and Next records within a GridView control?
View 3 RepliesIn my Gridview when a user edits a row, I'm showing couple of asp:TextBox boxes using the EditItemTemplate.
One of the Text Box is bound to the UpdateParameters of my asp:ObjectDataSource. However the Second Box is not bound to any of the update parameters. I'm assigning a custom value to the second box.
Now my problem is, when the row is updated how do i read the value of my second text box??
I tried catching the value of the second text box in Grid_RowUpdating and ObjectDataSource1_Updating but I'm unable to find the second control.
I have a grid view control having some bound and template fields as follows
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"
ReadOnly="True" SortExpression="ID" Visible="False" />
<asp:TemplateField HeaderText="Question">
<ItemTemplate>
<asp:LinkButton ID="btnques" runat="server" onclick="btnques_Click"
Text='<%# bind("Question") %>'></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
Now what I want to do is that on the click event of a buttom btnques, I want to access its corressponding boundfield ID's value and to store it in a label.

View 1 Repliesi have a customized gridview.my grid is able to sort for each column just by 1 click in the header without any setting and overloading methods such as sorting,etc by user(programmer).(i do this successfully and work fine)users(programmers) maybe add each column in grid.such as template field,hyperlinkfield,boundfield... .for sorting, i must access datafield of columns.i can access boundfield column by this code.i can access datafield and header text and ...
sample:
for (int j = 0; j < this.Columns.Count; j++)
{
BoundField bf;[code]....
but i can access control in the templateField.such as ColumnBound.
sample: <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
i want access "Name" (Bind ("Name") or Eval ("Name")) .how can i?there is a point: i dont now what is the ID (in this case "Label1") of control in templatefield.
I know that when you hide a control is asp.net that you cannot access it. Is there a way of hiding it as far as a panel? Can I put it in a panel but size the panel to 1x1? Or in a div and hide it?
View 2 RepliesI have an ASP.NET web form application that on the server side I need to know the user's identity. I do not need to impersonate the user. I just need their username so I can update some records in a database correctly.When the request is processed I have the following line of code:
string userName = Request.LogonUserIdentity.Name;
if(true == string.IsNullOrEmpty(userName))
{
logger.logwarning("missing username");
}
else
{
logger.loginfo("update by {0}", userName);
}
In my development & QA environment this works perfectly - I see the userName in the log file and all of the database records have the lastModifiedBy field filled in correctly. However, when we go to production - userName is an empty string.

Here is my situation: I use the SqlCommond to update some records in the SQL Server in a ASP.NET web site. Users can choose which records they want to update. Sometimes they may choose 40 or 60 records to update at a time.Is there any good way to do it? I do not want to do like it
foreach(string ID in List)
{
Update here
}
I have a datatable with some records.
i want that if record id is exists in database then update the record otherwise insert the record.
But i don't want to hit database again and again, i want to accomplish the task on a single hit.
I am tryin to get records where certain fields are empty, but the following sql does not give me correct result.
SELECT [specimen Type], [Year], [Lab Number]
From [PET Fish] where
ltrim(rtrim([Diagnosis])) = '' or
ltrim(rtrim([Results])) = '' or
ltrim(rtrim([Sign out Date])) = ''
It should return all records, but it returns none.
