Forms Data Controls :: FormView Doesn't Call Itemupdating Event?

Sep 26, 2010

So, to sum is up, I have a FormView:


And the relevant code:


What does work: I do see the right info if the formview is shown but when I click on the Update button it just doesnt fire the corresponding itemupdating event.

Can someone see what is wrong or missing?

What do I want to archieve: Just update the subscription's credits and its type: Upgrade, Prolong.


New finding: I added 'onitemcommand="fvSubscriptionEdit_ItemCommand"' to the formview and a corresponding event method with a simple code that throw a exception(just testing) but it doesnt enter the method but does whine when the method is missing. So why does it whine if the method is not there but doesnt enter the method if it does exist? I presume that this is the same problem.

Forms Data Controls :: FormView ItemUpdating / Custom Update For A Form View?

May 20, 2010

I need to do a custom update for a form view (I think/know), as some of the parameters that are required for updating values should not be updated by the users, such as userid of the person performing the action which is passed back to the database for auditing purposes.

Additionally, there are some fields, such as LastUpdatedBy, LastUpdatedDate that need to be seen, but not edited. The stored procedure on the backend takes care of this, and these are not parameters for the Update method. The FormView by default is trying to pass all these values back to the database.

Lasty, the select query of the object datasource is a stored procedure that performs several joins based on PF/FK relationships to bring back more meaningful information than just a FK, so some columns are just the joined value, and can not be updated directly. Again, formview is trying to pass these parameters

So given that, I have defined the following even handler for a simple form view:

(not sure if this is the way to proceed given the above, but...)

protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e)
ProjectDetailsDataSource.UpdateParameters.Add("projectID", ((Guid)e.Keys["ProjectID"]).ToString());
ProjectDetailsDataSource.UpdateParameters.Add("projectName", (string)e.NewValues["ProjectName"]);
ProjectDetailsDataSource.UpdateParameters.Add("description", (string)e.NewValues["Description"]);
ProjectDetailsDataSource.UpdateParameters.Add("projectTypeID", "1");
ProjectDetailsDataSource.UpdateParameters.Add("statusID", "1");
ProjectDetailsDataSource.UpdateParameters.Add("productID", null);
ProjectDetailsDataSource.UpdateParameters.Add("isComplete", ((bool)e.NewValues["IsComplete"]).ToString());
ProjectDetailsDataSource.UpdateParameters.Add("isActive", ((bool)e.NewValues["IsActive"]).ToString());
ProjectDetailsDataSource.UpdateParameters.Add("userid", Membership.GetUser().ProviderUserKey.ToString());
e.Cancel = true;

My questions are as follows:

1) Is this the right approach?

2) Is so, when I cancel the edit (because I did the update myself), and change mode, the FormView returns to read only mode as inteneded (good so far). However, when I hit F5 (refresh), the ItemUpdating method is called again, and updates the database.

Forms Data Controls :: Examine Data At "itemupdating" Event In Detailsview

Jan 11, 2011

I have a detailsview that is a mix of textboxes and dropdown lists. Upon clicking update - i want to examine all of the fields that have changed and do a custom update. I am trying to capture the data using the ItemUpdating method, capturing 'e' as detailsViewUpdateEventArgs. If i specify DataKeyNames in the ASP:DetailsView and only use one key (the primarykey) then i can step through the e.oldvalues and e.newvalues examining the data - but i don't have access to the field names (except for the single key i entered).

If i use all fields from the DetailsView in the DataKeyNames parameter - then i have access to all the fieldnames via e.keys(n) - but at that point i don't have access to the e.oldvalues (count=0) I am greedy - i want the keynames, the oldvalues and the newvalues.

Forms Data Controls :: How To Get Row Index From GridView After A Cell Is Updated

May 5, 2010

I have a simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.

I've added CommandName="myUpdateRowTotal" to
my templates.
<asp:TextBox ID="R01_Item_txt" CommandName="myUpdateRowTotal" runat="server" BackColor="White"
Font-Names="Arial" Font-Size="10pt" ForeColor="Blue"
Text='<%# Bind("R01_TARGET_COMMISSION", "{0:###,###,##0}") %>'

Forms Data Controls :: Image Not Updated Until Page Is Posted Again?

Dec 16, 2010

I have a datalist and gridview that have a image in a column.. when you click the imagebutton, its calls my method that updates a table. The page is posting during this event, but when the page is done, the image hasnt changed.. im sure it has to do with the datasource not binding during that click.. so where can i move this code to or can i simply bind the control during that click? Currently im handling it in the itemdatabound event.. which would explain it.. but where is the correct place to handle this logic?


The control on the page is configured like so..

There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview.

On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?

Any idea would be helpful.

Forms Data Controls :: How To Fill Databound Dropdowns Before Select The Updated Value

Jan 5, 2010

So I am using a formview that gets in Update mode with a bunch of values from a sqldatasource --- but I want to fill a couple dropdowns with data from the database --- but I cannot figure out how to bind the data to the dropdown box FIRST and then select the value in that dropdown box... but I keep getting an error that the Selected value is not a part of the dropdown (I assume because the sqldatasource is trying to bind BEFORE I can get the dropdown box bound).

IE -- when I load my values, lets say a 'Crop' comes back as 'Corn' ... I want to download the available crops from the database (ie. corn, beans, wheat, okra, etc.) and then set the selected value as CORN.... SO HOW do I get the dropdown filled BEFORE I try and bind the selected value?
