Data Controls :: Details View Does Not Contain A Definition For Cells
Oct 22, 2012
i am refering this link of gridview for my requirment For DetailsView what is the mistake? Error 18 'System.Web.UI.WebControls.DetailsView' does not contain a definition for 'Cells' and no extension method 'Cells' accepting a first argument of type 'System.Web.UI.WebControls.DetailsView' could be found (are you missing a using directive or an assembly reference?)
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
LoadData();

I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.

I have on a page a gridview that can be filtered with one text box. I set up the gridview to show select and wanted to then connect a details view so that when you selected a row the entire details would show up. When I run it I get this error. Data keys must be specified on GridView 'GridView1' before the selected data keys can be retrieved. Use the DataKeyNames property to specify data keys.

I'm trying to get a record to show up in a details view as part of a Master Details. I was able to get this to work by setting the visibility to true for the Details View in the Page Load event. I now want the details view to show up when the Select button is clicked in the GridView's template field using the onClick event for the button. I don't seem to be assigning the correct properties to get this to work though. what property I should use with this? I know I have to get it from the GridView and assign it to the details but haven't gotten it to work. this is the GridView:

I'm thinking of using a modal pop up control that would have a details view in it. I currently have a details view that uses CSS Friendly control adapters with the CssSelectorClass attribute. Can I use the CSS friendly CssSelectorClass property with a details view in the modal pop up and style it as I'm currently doing with my Details View?

I am using the following to retrieve selected value of a gridview
protected void gvDetail_RowDataBound(object sender, GridViewRowEventArgs e)
{
gvDetail.DataKeyNames = new string[] { "ID Number" };
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline';";
e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";
e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.gvIncidentDetail, "Select$" + e.Row.RowIndex);
}
}
The first time I click on any cells, it runs good, the second time i click on any cells of grid view, it prompts an error:

I have on one page a grid view that has a a delete bit and create new form, these both work. when the user clicks the edit button/link the id for that field is thrown in the url to a new page with a details view on with its default mode to "Edit". I have a stored procedure to update the SQL dB which works when run in SQL. however when the values are chaged in the details view, I click the update button and it says that it has succesfully updated and throws no errors... It has not?
I think the problem is getting the new values out of the details view. which i have been doing like this...
TextBox _AddressContactName = (TextBox)DetailsView1.FindControl("AddressContactName");
string s_AddressContactName = _AddressContactName.Text;
This gives me what the value that it was before editing and the same as in the dB, this is why i'm getting a successful bool value for the stored procedure. My question is this... how do i get the values after its been changed in the details view?

So question from a Newbie !So I have a web page with a Details View component for Inserting data into a table.One of the fields is a date/time which I want to be now().SO I guess there are 2 ways of doing it - either I populate the date/time field in the form with a variable that represent now() and make it Read Only so the user can't change it or I somehow make a hidden variable (ie not displayed in the form) that writes a date/time of now() into the database whenever an INSERT takes place.What is the best way and how do I do either of them ? How do I make one of the fields in the INSERT form of the Details View a preset variable ?

in one of the text fields I want to limit what the user can insert to a set of key words. So the obvious thing to do is to present the User with a drop down box to select a key word.
So I have converted the text field into a template and I thought I could replace the <InsertItemTemplate> in the details view with the drop down box.
Well it looks like what I want but when I INSERT the data that field is not inserted into the database.
So I guess I need to Bind the Drop Down somehow to the Insert - How do I do that ?
My code is below;

Am having a details view and grid view in a page. In details view I have one dropdown list with selected index changed.I have to take the values from database and bind it to the other fields in details view. I have Written the Query which is executing fine and fetching values(this one i have checked in SQLServer). But when i select any items in DDL, instead of binding it in DetailsView its getting binded to Grid view.

I have a method that retreives data from table and needs to display in details view. The method is give below: The problem I am facing is I did put some break points to figure out if all the lines are executed but the problem I am facing is that the compiler is not going in the while(reader.read()) loop(I have made to loop bold so that would be easy to locate) and hence unable to retreive data.
public static Workstation GetWorkstationByName(string workstationName)
{
Workstation computer = new Workstation();
string key = "workstation_workstation_" + workstationName;
if (workstationName == null)
return null;
if (SiteUtility.Cache[key] == null)
{
string con = SiteProvider.Instance.AltirisConnectionString;
List<Workstation> workstationlist = new List<Workstation>();
SqlConnection cn = new SqlConnection(con);
SqlCommand cmd = new SqlCommand("Select [Server] from vComputer where Name = '@workstationName';", cn);
cn.Open();
cmd.Parameters.Add("@workstationName", SqlDbType.VarChar).Value = workstationName;
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
Workstation ws = new Workstation();
ws.Server = reader["Server"] as string;
workstationlist.Add(ws);

I have a details view that currently shows the positionID when displaying data in select mode. This corresponds with the way the stored procedure was written. I've decide I want to display the PositionName though. I want to know the best way to do this.
I know I can rewrite the procedure to pull the PositionName instead but I thought there might be another way of doing it. Rewriting the stored procedure to pull the name instead of the ID may be the best way to do this. I thought there was probably a way to cross reference the position Id with the name. If there is then it may be unnecessarily cumbersome and not worth doing.
I also want to be able to pass the id to the Details view when it is in edit mode so a drop down that lists the position names will start with the correct current value selected when in edit mode. This would prevent the value from being accidentally changed. I'm not sure if I rewrite the procedure to return the PositionName instead of the PositionID that it won't cause issues with me wanting the drop down in edit mode to start with the correct value by passing the PositionID. The Position is stored as an int for PositionID in the db.
This is the current field in the Details View:
