For some reason I seem to be unable to update my DB through the datasource. Is there anything obvious as to why this wouldn't be working?
I even added static values to the update string to see if this works but it still has an issue.
I made a project to use the access membership provider from [URL] 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:

Unable to add update and delete functionality to any data control using MS Visual Web developer Express and SQL server 2008. The advanced options in the data connection wizard remain disabled. I can display data OK.
I am however able to connect to an Access 2007 DB through the same page and get this functionality to work.
I am trying to update the row using gridview_rowupdating event but I am unable to update. I tried the code like this...
foreach (GridViewRow i in GridView1.Rows)
{
TextBox sname = i.FindControl("sname") as TextBox;
TextBox fname = i.FindControl("fname") as TextBox;
TextBox sex = i.FindControl("txtsex") as TextBox;
// Label lblpin1 = i.FindControl("lblpin") as Label;
TextBox tpin = i.FindControl("txtpin") as TextBox;
tpin.Enabled = true;
// lblpin1.Enabled = true;
string pinno;
pinno = Convert.ToString(tpin.Text.Trim());
conn2.Open();
SqlCommand cmd = new SqlCommand("update NRDetails2010 set SNAME='" + sname + "',FNAME='" + fname + "',SEX='" + sex + "' where pin='" + pinno.Trim() + "' and InstCode='" + Session["UId"] + "' and Sem='" + ddlsem.SelectedItem.Text + "' and scheme='"
+ ddlscheme.SelectedItem.Text.Trim() + "' ", conn2);
cmd.ExecuteNonQuery();
conn2.Close();
}
I am getting error at cmd.ExecuteNonQuery()
Here I am giving connection globally and opening in this event. In gridview, I am updating 3 fields depending on 4 conditions.
I have my data table generated dynamically binded to grid view. (Autogeneratecolumns true)
in my UI its displaying the column headers.
am not able to access it by grdname.HeaderRow.Cells[0].Text
am not able to get the names from the columns also.
since am binding the columns dynamically i am not able to get access to all the columns
and am able to get only 2 columns which i have mentioned in my aspx which are the command buttons edit and delete.
am trying to access all these in Gridview_RowCommand event. need to get the value in the (dynamic) column named Id for the row on which the edit or delete button is clicked. since it doesnt have a header am unable to access it bcoz i dont know the index of the cell too..
I am unable to access the data in the gridview's selected row. I have done this lots of times but must be forgetting something.

There is a field called school which is a dropdown menu, I manually edit items and made it like these: select school, name of 6 elementaries and 2 middle schools, and a high school.I have another field called grade level, which is a drop down menu too, i manually entered the grade items for it: select grade, Kindergarten, 1, 2, 3......12.
I would like after user selects a school in the drop down menu, the field called grade level dropdown box' data source will be updated according to school. For example, if it is a middle school selected, the data source of grade level will be updated to 6, 7 8 grade, if it is elementary the grade will be updated to 1, 2, 3, 4 5 etc. In this way later, when user goes to select grade it will show appropriate grade level lists according to schools.

View 7 Repliesi have the code to test:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =8", Con)
Now, I need something like this:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" + LblInfoEditar.text, Con)
The problem:
The LblInfoEditar is outside the datalist so it works fine. (note: in this label I put a value like the 8)
But I have this label to test because I need to access a label inside datalist:
<asp:Label Visible="false" runat="server" ID="LblNumEntrevista" Text='<%# Container.DataItem("EntrevistadoCodigo") %>'></asp:Label>
The problem is: in this line I've to put something to access this LblNumEntrevista HOW?
I try:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" +
ListaPendentes.LblInfoEditar.text, Con)
But of course I don't work because I can't do this...
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I also posted my question on another web site, one suggestion I got is move my codes to codebehind

But this is ObjectDataSources, my understanding is everything have to stay in Class file.
I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?

I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.

I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?
