Forms Data Controls :: Using A Selected Row In GridView As Part Of The Where Clause On FormView??
May 15, 2010
I am fairly new to Visual Web Developer so I hope this makes sense.I have a page with a GridView (code below). When a person clicks on the Select Link, I would like it to direct them to a page with a FormView of the selected row so that it can be edited. I feel that this should be fairly basic but am having trouble finding the means to make it happen.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
DataSourceID="SqlDataSource1" Height="230px" Width="829px"
AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" [code]....

I have a FormView in default insert mode.
When I inserted item to database, the Form refresh and return to all blank or standard selection.
What can I do if I want it keeps the last entered value after inserting record ?
I need this because there are many items to insert and only partial fields need changes from last entered records.

I have a sql-bound formview with three DDL's bound to individual SQL datasources. In edit mode, I want to set the selected value to the formview's value, and this works:
<asp:DropDownList
ID="ddl2"
runat="server"
DataSourceID="ddl2lDS"
DataValueField="Name"
SelectedValue='<%# Eval("Name") %>'
/>
But it only works when there's a match between what's in the formview's DS and the DDL's DS.
Unfortunately, there may be instances where the the formview's DS may return a null value or a value different from the DDL's datasource...and when that happens I receive a compilation error like:
'ddl2' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
What do I need to do to trap that condition before attempting to set the selected value? Do I need to set the selected value of the DDL in formview's dataBinding or dataBound event, by looping through the DDL and checking for a match first?

I want to PIN the header part of my DataGrid or GridView? How is it possible? Ex: Suppose we have 100 rows in data grid, and 1 row with header. If you scroll data grid, header row shouldn't scroll. It should be fixed or PINNED. Only rows with data should scroll. Is there any in built function in data grid to achieve this functionality or any other methods to do this?

I have a Formview that is only showing a question, and two checkboxes (True / False). It's cumbersome for the client to have to click "Update" every time they click a checkbox.
Is there a way to have Formview update the data when the page is changed, or form is closed? (I see those events, but know how to force data to update from in them).The application is testing individuals, so 95% of the time the person navigating through the forms will be updating data.

I have a set of 4 buttons which part of a gridview template and I load the gridview on page_load. The datasource for the gridview comes via my controller as I am using Microsoft's Model View Controller design pattern. I set 4 public properties for each of the 4 buttons, which I can access in my controller class/method. However, when I call the method for the gridview, which sets the datasource for it on page_load, I get an error message when I try to set the enable to false. It says "Object not set to instance of object". The objective I am trying to do here is a check on a returned value, which I can achieve, and based on the return of the value that is returned, to either set the button enable to true or to false.
Unfortunately, I am getting this Object not set to instance of object error message, and I do not know how to resolve it.

I have a gridview like this :
[code]....
I have done this before "n" number of times but I am not able to get it working this time. The trouble is that when the call for the Select Method of the formview goes to the relevant function - "GetCustomerByCusnum" I have a null value in its parameter "cusnum".
I know that I can write a selecting event and using CommandArgument, parse the value of the selected row and pass it into the Select method as a value but I dont want that solution. I know it works without the "Selecting" method but I cant recall how.

I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

I have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.
Here is the page and the selectedIndexChanged sub for the piece of work I'm trying to accomplish...

In my webpage I have a Formview bounded by sqldatasource. I can perfectly Update data from it. In the same page I have a gridview bounded by some other sqldatasource. I have to give user new record option from gridview.
I know that there is no default property to insert new record with the help of gridview until we provide some other way by coding but I don't want to do that.
Therefore I have taken a textbox with the validation field and a button outside the gridview to insert new record into gridview and refresh it.
I don't want to allow user to add empty text using textbox thatswhy I have validated that textbox.
Problem:
If user has the scenario to update only the Formview then he cannot because there is a validation there with the textbox.
If I remove the validation then user is able to update FormView perfectly but may add empty text from the textbox.
if the user allowed to update FormView and to add data with the help of textbox and gridview get refresh. If user can do only one task also either to update FormView or to add data from textbox to refresh gridview.
The task is most important for me and I have only 12 hours to complete this task or you can say the time limit is going to expire.

I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?

I have used this forum a lot to guide me before, but now I have a problem which I cannot find a solution to.
I have used GridViews to open either DetailsView or FormView, so I understand that part to some extent.
This time, I have a FormView that includes a HyperLink, which is displayed when page comes up.
The user will click on this HyperLink to open a NEW GridView to be placed in the bottom of the page.
[Code]....
Maybe the NavigateUrl cannot be used in this way ?
Should I use a button in the FormView to launch my second GridView ?

How do I get the Gridview to update when the panel is updated?

I have an ObjectDataSource giving me data similar to: OrderNumber OrderDate OrderValue OrderItems The first three are simple data types and the last has multiple occurrences of another class: OrderLineNumber OrderItem OrderQuantity The ObjectDataSource will only contain one row (which might make things simpler). So, there will be one OrderNumber, OrderDate and OrderValue; and then several occurrences of OrderItems (each containing OrderLineNumber, OrderItem and OrderQuantity).
I am displaying OrderNumber, OrderDate and OrderValue in the FormView - that work's fine, as expected. I have placed a GridView within the FormView and am failing miserably to get it to bind to OrderItems. I have tried the obvious things like specifying "odsWhatever.OrderItems" as the DataSourceID for the GridView, but to no avail.
