Forms Data Controls :: Gridview Is Not Updating And Deleting Without ID Column?

Dec 1, 2010

I have a gridview in which update and delete is enabled.

I have the following fields in database table, which is binded to the grid view through sql datasource.

ID,Firstname,Lastname,Add,City,modifieddate. Here ID is primary key.

1. When edit and delete is enabled in the grid. The ID column is showing in the grid,which i don't want to show. But without that ID column the grid is not able to update and delete. Plz tel me how to update and delete without ID column in grid.

2. When ever any update is happen in the grid, the modifieddate should get updated. Here the date is not datetime.now , i need to use my own system date and time. Coz my server and system time has some difference.

I have use the following javascript to get system date and time, which is working fine. This date should be get and update in the modified column.

function displayTime() {
var m_names = new Array("Jan", "Feb", "Mar",
"Apr", "May", "Jun", "Jul", "Aug", "Sep",
"Oct", "Nov", "Dec");
var localTime = new Date();
var year = localTime.getYear();
var month = localTime.getMonth() + 1;
var date = localTime.getDate();
var hours = localTime.getHours();
var minutes = localTime.getMinutes();
var seconds = localTime.getSeconds();
var div = document.getElementById("TextBox1");
div.innerText = date + "-" + m_names[month] + "-" + year;
}

Forms Data Controls :: Deleting / Updating Record From SQL Database Via GridView

May 11, 2010

I've been googling for 2 days for the solution, but I couldn't find something useful. The problem is that I have GridView that is connected to the SQL database and that is how it is being populated. I added EDIT and DELETE buttons in the columns, but as far as I can see the event which handles them is empty.

Forms Data Controls :: Update DetailsView Data By Updating Object?

Mar 23, 2010

I'm using a DetailsView object to present a record from a database in table format. I'm actually using and ObjectSource object as the data source for the details view. In the object I am using as the source for the ObjectSource, I have paired properties that hold decimals. This is, I have a property called Year1 and another property called Year1Change. This for years 1 to six. The values from the Year1 properties are in a cell, whereas the change values are bound to texboxes. The code for the frontend is the following:

[Code]....

Now, as you can see in the tbYr2RtCh textbox, I have an OnTextChanged property to call an event handler. This is because I want to do two things when the text changes. The first one is to make the font in the textbox bold if the value it holds is different from the Year2 property. The second one is to change the text on tbYr2RevCh to adjust the revenue for the percentage increase in the rate. The problem I have is that I cannot access the object that is the source for the data and make those changes directly in the object, instead of having to update the database. I don't want to update the database until the client says so, but the changes should be calculated immediately. I thought about creating an method in the object that I could specify in the ObjectDataSource as the update method, but I'm still not sure how to go about it.

Forms Data Controls :: How To Stop A Detailsview From Inserting Or Updating

Aug 12, 2010

Here is the scenerio:I have a radtabstrip (with 2 tabs) at the top of my page followed by radMultiPage control Tab 1 displays pageview 1 which has a gridview showing data from our database and allows for selection or deletion of data tab 2 displays a detailsview when gridview_selectedindexchanged(from tab 1) is fired.Problem... If you select an entry in the gridview it switech the page and the detailsview into editmode (works fine) but if you then click on tab 1 without clicking update or cancel in the detailsview, the data is updated. This is what i don't want as the user has basically abandoned the changes.So what i need is a what to say ... if the detailsview is in edit or insert when the tabstrip is clicked then cancel the insert or update. I tried switching it back to readonly mode but that did not seem to work.

Forms Data Controls :: All Row In MS Access Table Are Updating With Detailsview Edit?

Nov 22, 2010

I have used this before with no issues. Now I get to the page with the detailsview using parms I pass with the key to the row. When the page opens the row I want to update is displayed.

I am having 2 issues. One when I change any of the fields and hit Update (the Edit button),

all rows are updating not just the row displayed. The second problem is I have an update_date and an Updated_by field with code in code behind in the Onitemupdating event and they are not updating at all. (This bit of code works fine in another page I have to updated similar fields on an insert).

Forms Data Controls :: Updating Two Detailsview Controls With Paging?

Mar 11, 2010

have two detailsview controls on the same page, one showing pictures, one showing the comment on the current picture. I separated them because they are in different parts of the page (just in case someone was wondering why). They both bind on the same objectdatasource. The issue is that since I use paging to navigate the pictures and i dont know how to also update the comment detailsview control to the same page as the picture.

Forms Data Controls :: DetailsView BoundFields Auto Binding Not Updating Business Object On Update

Feb 18, 2010

I have a DetailsView (DV) control, an ObjectDataSource (ODS) control, and a button on a page. I have 2 classes in the App_Code directory (Customer and CustomerDAO). The DAO class provides static methods for the ODS control and simply hack values in (ie...no real database selects/updates). The Customer class has 2 properties (Id and Name) and a default constructor. The page takes an ID on the querystring and determines if the DV control is in insert or edit mode. If in edit mode, it sets the SelectParameter on the ODS (id field), calls ODS.Select(), and then calls DV.DataBind(). The existing (although fake) customer is loaded and display properly when this happens. I then change the name of the Customer in the DV and click the Button to save the new data.

Everything seems to be wired up correctly as the UpdateMethod that is specified in the ODS control is called and succeeds (even in my real example with my database). The problem is that the BoundFields in the DV control have not been updated with the new values and therefore the existing values are updated in the database and my changes are lost. I have handled the OnUpdating event of the ODS and the values are still the old values. I have also handled the OnItemUpdating event of the DV control and the NewValues IOrderedDictionary still has the old values in it also. In looking at the MSDN article for the UpdateMethod, it states the following:

Parameter Merging
Parameters are added to the UpdateParameters collection from three sources:

From the data-bound control, at run time.
From the UpdateParameters element, declaratively.
From the Updating event handler, programmatically.

I am using the BoundField classes in my DV control so I would have assumed that the first bullet above would have handled the updating of values, but it doesn't appear to work with the way I am doing it. If I set the values explicitly in the OnUpdating event that is fired by the ODS control (the 3rd bullet) the right values are updated (again...even in my real database situation). It seems like my only issue is that the automatic binding that I expect from the DV control isn't working as I would expect it to. Here is the code that I have in my fake example:

Forms Data Controls :: Gridview And Detailsview - To Click Two Times On The Select Button To View The Detailsview?

Nov 17, 2010

Im trying to link the gridview to detailsview and I used this page as my inspiration:

http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx

But Im trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

C# - How To Write Binary Data "as Is" To Registry (ie: I Have Visible Binary Data As String From Regedit Only)

Feb 23, 2011

I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out... I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically.

here is the culprit!

[Code]...

If I had the following in a string or a bit array, what must I populate the bitarray with so that the registry outputs this [above] when written? or, how can I figure out how to do it? I was hoping there'd be a function that reads my string of binary data and transforms it into the real binary format to submit to the RegSetValueEx function in VB6 or other function in VB.Net or C# (this really is a language agnostic question, and the problem exists in all languages; ie: same process).
