I have a GV that is populated via a reader: Using reader As SqlDataReader = cmd.ExecuteReader() I have autogenerate edit button=T but it will not go into editmode. Must I create template to handle this?
View 4 RepliesSo far i've populated my grid view with my roomID. however using data reader I don't seem to be able to get more than one column to auto generate even though i'm now looking for three values : SELECT tt_roomEquip.roomID, tt_room.roomCapacity, tt_equip.equipTitle is my select bit of the sql, though it's only putting roomID into my grid view.
View 1 RepliesI have a listview and inside the listview I have a gridview. I'm binding data to the listview, then on the listview itemdatabound I'm binding the gridview. I want to make the gridview editable so I have an edit template and an edit command button. I have the event rowediting and inside there I set the edit index. Now normally I rebind the control and everything works. But if I rebind this gridview, nothing happens.
I can trace through the rowediting and everything is working. It's setting the edit index, it goes through the databind and gets the right data and binds it to the control. What is happening? Why isn't my rebound edit mode gridview showing up?
I have a GridView in MultiView and everything works fine. When page load everything looks good,but then when i try to edit something in my gridview it does postback and the whole gridview disappear from the multiview.
View 1 RepliesI have a Gridview that shows my data, I allowed it to have Editing and Sorting. I have achieved refreshing my GV with <META HTTP-EQUIV="Refresh" CONTENT="15">. however, when I Edit and it hits the time to refresh, I loose the Edit mode and starts at the beginning of the grid (I need to find the data again.) Is it possible to still have the refresh (15secs) then when Iam in EditMode, the Refresh stops, then after I have clicked UPDATE. the refresh time starts to count again. (i use VB)
View 7 RepliesI don't know how to do this, I think I need to find the control first.

Here is what I have tried:
txtCost.Text = string.Format("{o:c}", dr["Cost"]);
Here is the error I receive. How can I format the data that is coming from the data reader into currency format??? Also, is there a way to format it into currency without the dollar sign?

View 3 RepliesI'm using a Gridview in VS2008 framework 2.0 to edit a field with standard edit/save/cancel buttons on each row. I have a textbox named TextBox1 in an EditItemTemplate tag, it's value is binded to my field with '<%#Bind("LOGIN_NM")%>'. This is a simple form a took from an old project. My problem is when I try to read the textbox in the GridView1_RowUpdating event, it keeps returning the original value and not the modified value. I spent some time figuring the cells, controls and all so I'm sure I'm reading the right textbox, I have only one. I also tried using:
CType(row.FindControl("TextBox1"), TextBox).Text but I can't get the modified text to store in the database. The exact same thing works in the old project.
by default, my formview loads up to Editmode and it looks like this:

Problem is if binding is not ran during postback here, buttons on the ItemInsert mode DO work, but the button on the ItemEdit mode DON'T work. However, if I don't bind the fv1 here during postback, controls will not load on the formview ItemEdit mode and databinding will not occur.
i have a detailstview and sql datasource I am retrieveing the data so far no problems but afteradding a dropdownlist in edit mode and clicking edit button I get this error"
'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value.[Code]....
I have a simple FormView (fvDespatchPart) which updates the status of an order and it's despatch date; the despatch date being retrieved from a textbox (txtRentalDespatchDate)
held within the FormView. The FormView's DefaultMode is set to Edit.
I have been trying to set the default entry for txtRentalDespatchDate to today's date in the code behind, using:
Dim dtNow As Date = Today()
Dim txtRentalDespatchDate As Webcontrols.Textbox = fvDespatchPart.FindControl("txtRentalDespatchDate") [code].....
I have had no trouble doing this in the past with FormViews whose default mode is set to Insert or Item, but in Edit mode it just does not seem to want to co-operate. I have read a few help posts, and have tried:
Putting that code in LoadComplete, PreRender, PreRenderComplete Page events, as well as the FormView's databound event. I've also tried nesting it within a ...
If fvDespatchPart.CurrentMode = FormViewMode.Edit Then
End If
... just to make sure if is in the right mode.
Nothing yet has resulted in anything but the same old error.
I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
how I can loop through the results in VB, I only ever seem to get the last row, I would like to list all rows.
My code is below

I have created a SQL DB in Visual Web Developer Express Edition and i am using a aspx form with connection strings and grid views to call the information but the problem i have is that i wish to insert an image into the database and i have tried numorus ways and i can't seem to even put the image in the DB let alone call it in the grid view.

I have 2 textboxes and two sqldatasources in page. So i want to take value from the textbox and put it in the Sql Query.
I want that because this textbox i'm using for searching people in Phone Directory.
Here's the one textbox and the one sqldatasource code:
<asp:SqlDataSource ID="ResidentDetails4" runat="server" ProviderName="System.Data.SqlClient" ConnectionString="<%$ ConnectionStrings:ThisIsMyConnection%>"
I'm quite new to ASP.NET and i was wondering if someone could answer some of my questions.1. What is the difference between a DataTable and an Array? Is the DataTable a serverside control? Is it exposed to the user?2. Does the reader retrieve the column names? If so- how can I capture them? Are they the first row?2. Is it possible to populate an Array using the following sort of code, and if so- how?:
SqlCommand tableCommand = new SqlCommand();
SqlConnection tableConnection = new SqlConnection();
tableCommand.Connection = tableConnection;

...so when I get to commit the transaction it raises the mentioned exception: "This SqlTransaction has completed; it is no longer usable".

I have been able to successfully read a row of data from an SQL table using two column parameters. Now I would like to update this row with new information. Is this possible since the reader does not specify which row was read with the 'reader.Read();' command?

Environment is : vwd2008, asp.net 3.5, linq to sql object model, formview, stored procedure used for query.On going problem... I have a simplified page with a webform content area from a master page. The content area contains a FormView connected to an object data source thru the design view tag. The O/R designer has the Lease Table and the stored procedure in the method area.
The stored procedure selects all records from a single table. I an using the DatabaseDataContext and selecting stored procedure name which has "return SingleResult".. There is no code written; the design view was used to create everything. The stored procedure executes in VWD 2008 express tab and shows desired records. I would like to use the O/R and Linq to SQL, and objectdatasource BUT.
