I have an TabContainer which contains a user control. The user control contains a formview. When I try to update the formview I get an error "Object reference not set to an instance of an object". I had the formview in the tabpanel and it worked. I decided to make it a user control just to clean it up a bit since I have several tabs, each containing formviews or grids.

I have a Tabcontainer which contains formview1 in first tab and formview2 in second tab. I am not able to give Control based where Selectedvalue condition for formview2 datasource. I mean VS2008 is not picking it up automatically when I try to configure where condition. What should I have to do to make formview2 to make it working.
View 3 RepliesI am trying to use a tabContainer and two tabPanels inside a ItemTemplate of a Formview.
As soon I put them in the ItemTemplate I receive the following error on the formView control in design view:
"There was an error rendering the control. Could not find any resources appropriate for the specifie culture or the neutral culture. Make sure AjaxControlToolKit.Properties.Resources.NET4.Resources was correctly embedded or linked into assembly AjaxControlToolKit at compile time, or that all the satellite assemblies required are loadable and fully signed.
I have a scriptManager tag in the master page and an updatePanel in the content page.
I use a border for the TabContainer body which works fine.

also I use three hidden divs and one visible div inside a main div which works as body of Tabcontainer
I have a webform that has a formview (fvwContract) and inside itemtemplate there is a Tabcontainer with three tabs (invoice (spanish: factura), receipt (spanish: recibo) and beneficiary (spanish: beneficiario). I have another formview inside invoice tab (fvwFactura) with many textboxes that I need to manipulate in code behind. The thing is that I canīt reference any of them like the following:
protected void DropDownList1_SelectedIndexChanged2(object sender, EventArgs e)
{
AjaxControlToolkit.TabContainer container = (AjaxControlToolkit.TabContainer)fvwContract.FindControl("TabContainer1");
FormView myforma = (FormView)container.FindControl("fvwFactura");
TextBox txtdos = (TextBox)myforma.Row.FindControl("txt2");
Label lbldos = (Label)myforma.Row.FindControl("lbl1");
lbldos.Text = "sample1";
txtdos.Text = "sample2";
}
I just don't know how to reference any control inside frwContract.TabContainer1.fvwFactura
Time for my daily ASP.NET question.
One of my pages shows all of our customer information from a customer table. I want the user to choose whether to see all customer records, or select a specific record from a list. So, my webpage has two radio buttons (show all customers, show specific customer), a listbox (full of customer names), and a formview control. The problem I'm having is getting the formview to update when I change modes via radio buttons or listbox selection (see code below).

I am using a stored procedure for a sqldatasource to update a formview. I believe that I am passing the Obligation_Status value correctly to the stored procedure but the oblgation status field is always updated AS NULL in the database. Does anyone know what I am doing wrong?

One of the fields on my formview is a dropdownlist. When I go into edit mode the dropdownlist gets set to the correct value and works fine up to this point. Problem is I just can't see how to get the newly selected value of the dropdownlist to persist to the database when update is clicked. The DDL is a category list and I want to allow changing of the category for each record. Like I said I have it working so it displays the correct category for the record but if I change the DDL (change category) the new selected value doesn't get updated in the database. It just keeps using the binded value that was originally assigned to the selected value of the DDL. see code snippit
[Code]....
The above snippet is how I am binding the DDL. Now to not bore you with a ton of code paste I use various events of the formview to make sure the value displayed in the DDL is correct for the record that I am viewing at the time. All that works just fine. Where I need some pointers is the when I enter edit mode and change the DDL from say fire to ice it isn't getting persited to the database, all other info in the record gets updated just fine but the DDL never changes. I have tried several angles to getting this working and TBH my brain is yelling BREAK TIME.
why my formView control is not updating?

We have a page that contains a loginView and in the LoggedinTemplate is a FormViewTemplate. The display part works fine.
Not all fields are databound due to special hadling needed on diaplay anu onUpdating. The display part works fine. However in the onUpDating procedure. I can't figure out HOW to gain Access to the field content in unBound FormView Fields. I need that to determine and set the output fields that need special handling.
I tried from the formView

I want to bind an object to a form view.

Now, is it possible to generate a new object on update, without getting and reading each textbox with findcontrol?
I have a strange issue with the FormView. After working through some issues getting the update to work (as this is my first experience with FormViews) I now have a new issue. After I perform an update, and the FormView updates and returns to read mode, if I hit F5 (refresh) the FormView performs another update to the datasource, despite the fact it is read-only mode and none of the fields on the screen are editable.
I would think that a refresh in read mode for the FormView after an edit would simply refresh the data from the database, not perform another update. Again, the FormView is in Read Only Mode, but a refresh is creating another Update event (which I can debug and see if I break in the ItemUpdating event). This only happens after I perform an edit, not when the page initially loads.
I have an access database where when the record is updated I would like to automatically check a box and update the date to the current date in an Access 2002-2003 database. I've tried this for several days without any resolution and can't find anything that works on the net. ...I'm new at this.

At present we are using <ajax:TabContainer> to load tabs. I have 5 user controls inside <ajax:TabPanel>.
The problem is that all the data on these 5 pages gets loaded at once and increases the loading time as well as it is very hard to debug. Can we do lazy loading uisng TabContainer control? so that only the data of the current tab is loaded and when we click on the other tab then that's control data gets loaded.
m kinda new in asp.net ,i'm try to do a web form with 3 tabs but i want that the tabs will start from the right end of the screen and not from the left?is there a way to do it?i searched the properties list for such a thing , and i didn't fine it.

View 2 Replieshow to get vertical tab using tabcontainer in ajax controls.
View 2 RepliesHaving a strange issue with the TabContainer in the AJAX Toolkit. We have several views into a customer record system that we have built as ASP.net controls. These controls use UpdatePanels to load data asynchronously. We use jQuery and jquery.ui to place these controls in separate tabs on a single page. Which all works swimmingly. Lately, I've gotten a little tired of the jQuery tab hackish approach and decided to port everything to use the TabContainer. I want to be able to control the tabs as objects.
At first glance, everything works perfectly. I just slapped the controls into tabs in a TabContainer and everything looked great. However, for some reason, databound controls are losing their data. For instance, grid views vanish when I switch pages. A drop down control with an OnTextChanged event, loses its databound list of values upon post back. Something about the TabContainer -> Custom Control -> UpdatePanel -> Control that uses data binding heirarchy is throwing it out of whack and the debugger isn't shedding any light. It seems like control state isn't being stored. I don't really know enough about control state to know what to look for. Here is the markup for the TabContainer:
<asp:TabContainer ID="tcBanner" runat="server" ActiveTabIndex="0" Width="100%"
EnableViewState="False" ScrollBars="Vertical">
<asp:TabPanel runat="server" HeaderText="Comments" ID="tbComments">
<ContentTemplate>
<luBannerControl:Comments ID="commentsTabContent" runat="server" />
</ContentTemplate>
</asp:TabPanel>
<asp:TabPanel runat="server" HeaderText="General" ID="tbContact">
<ContentTemplate>
<luBannerControl:Contact ID="contactTabContent" runat="server" />
</ContentTemplate>
</asp:TabPanel>
</asp:TabContainer>
Here is the markup for one of the controls:
<asp:UpdatePanel ID="pnlComments" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:GridView ID="CommentsGridView" AllowPaging="true" PageSize="20" DataSourceID="BannerSqlDataSource" runat="server" AutoGenerateColumns="False" GridLines="None" CssClass="CommentGrid" HeaderStyle-CssClass="CommentGridHeader" RowStyle-CssClass="CommentRowsEven" AlternatingRowStyle-CssClass="CommentRowsOdd">
<Columns>
<asp:BoundField DataField="SPRCMNT_TEXT" HeaderText="Comment" SortExpression="SPRCMNT_TEXT" />
<asp:BoundField DataField="SPRCMNT_DATE" HeaderText="Created" SortExpression="SPRCMNT_DATE" DataFormatString="{0:M/dd/yyyy}" />
<asp:BoundField DataField="SPRCMNT_CMTT_CODE" HeaderText="Type" SortExpression="SPRCMNT_CMTT_CODE" />
<asp:BoundField DataField="SPRCMNT_CTYP_CODE" HeaderText="Source" SortExpression="SPRCMNT_CTYP_CODE" />
<asp:BoundField DataField="sprcmnt_user_id" HeaderText="User" SortExpression="sprcmnt_user_id" />
</Columns>
</asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="txtSearch" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="btnClearFilter" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I want to add a close button on each tab,just like the firefox.
It seams that Ajax Control Toolkit doesn't provide any method to close the tab.
I have try to use the .Remove() function,but it doesn't delete the tab...it just make it invisible and work correctly only once....
Could any give the code in C#..
