Forms Data Controls :: Refresh Databound Control On AJAX Tab?
Jan 6, 2010
I have an AJAX tab container with 2 panels within aspx page. Each panel hosts an ascx control. Each control contains GridView and FormView that are databound - 1st control to the parent table and 2nd - to the child. The 2nd control/tab contains standard DropDownList that is bound to the parent values so the user can select a parent to create "child" for. everything works fine except when the parent (on the 1st tab control) is created/updates the ObjectDataSource on the 2nd tab does not getting refreshed. Only after refreshing the hole page I can see the new "parent" value in the ddl on "child" page. I use strongly typed dataset. How I can programmatically refresh the DataSource? Simple rebinding didn't make a dent. Do I need to refresh page, the tab container, tab panel?

I've been working on a colleagues site, and have been unable to fix a coupld of issues with it. One of which is a refresh of a Gridview panel.
The page allows a user to navigate a tree structure and then display the permissions on a user selected folder. Permissions are then added/removed and Saved.
What's not happening is the saved changes aren't being refreshed in the Gridview, also after doing this process once selecting another folder doesn't refresh the Gridview either.

I want to render something like this (with ASP.Net Controls in the codebehind):
<ul>
<li class="first"><h1>This is a caption</h1></li>
<li><a href="#" title="" target="_self">Foo</a></li>
<li><a href="#" title="" target="_self">Foo1</a></li>
<li><a href="#" title="" target="_self">Foo2</a></li>
<li><a href="#" title="" target="_self">Foo3</a></li>
<li><a href="#" title="" target="_self">Foo4</a></li>
</ul>
<ul>
<li class="first"><h1>This is a another caption</h1></li>
<li><a href="#" title="" target="_self">Foo5</a></li>
<li><a href="#" title="" target="_self">Foo6</a></li>
<li><a href="#" title="" target="_self">Foo7</a></li>
<li><a href="#" title="" target="_self">Foo8</a></li>
<li><a href="#" title="" target="_self">Foo9</a></li>
<li><a href="#" title="" target="_self">Foo10</a></li>
<li><a href="#" title="" target="_self">Foo11</a></li>
</ul>
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.

I have a repeater I've databound with a generic arraylist from a LINQ query (.ToList() ) in the code behind.
I was using
<%# Bind("FirstName")%> but noticed
<%# Eval("FirstName")%> works just as well.
Is it better to use Eval or Bind? or does it depend on the situation?

I need a form that displays three columns drawn directly from a database (no problems here) as well as two fields that require some complex calculations. Not only am I lost as to how to incorporate the calculations into the control, I don't know exactly how to write the calculations. I am working in Visual Web Developer 2008 with Vb.NET.
The first of the two fields should take the sum of all payments made by a given customer and divide it by a DailyMembershipRate, returning a DaysPaid variable. It should take this variable and a CustomerSince field for that particular customer and calculate a PaidThrough field.
The second of the two columns similarly requires the DaysPaid variable described above. It should subtract the CustomerSince field from the current date and return the value in days, giving a MembershipDays variable. Finally, it should subtract MembershipDays from the DaysPaid variable, again returning a value in days, and then multiply this by the DailyRate value for a Credit/Deficit field.
I realize this is a lot, but I haven't been able to find any documentation either online or in VWD or ASP.NET texts on this topic. I could really use some fellow user input.

I have DataList control and I want to assign to it's edititemtemplate some User Control. The problem is I can't find when I should databound UserControl to data, as my UserControl doesn't have static look (it renders different depending on some property values and datasource).
I was try to simply set my user control in edititemtemplate
<EditItemTemplate>
<uc:MyUserControl id="myUserControl1" runat="server" />
</EditItemTemplate>
and then bind it to data in ItemDataBound event handler, but it remains empty
if(e.Item.ItemType == ListItemType.EditItem)
{
var p = (Pair)DataBinder.GetPropertyValue(e.Item.DataItem, "Key");
((AnnouncementUserControl) e.Item.FindControl("userControl1")).RepeaterDataSource =
_templateWorker.ReturnTemplateByAnnouncementId(Convert.ToInt32(p.First), true);
}
how can I databound my control, or another approach which will make me avoid this problem?

I'm working on a website to showcase some of my bird photography, using ASP.NET 2.0 and C# with a SQLServerExpress backend.What I have right now is a ListBox bound to my database that displays a list of common names of birds and when the user clicks on an item in the listbox the main image on the page is changed to the image for that bird. For style reasons I want the listbox to always be a fixed size and because I specify the size (using CSS) a vertical scrollbar appears. My problem is that I want to provide my own images of arrows that go above and below the box such that when the user hovers over an arrow the box scrolls slowly and when the user clicks an arow the box scrolls quickly. Finally, my main problem is that I want to get rid of the ugly default vertical scrollbar that comes with ListBox.
Can you guys help me figure out how to do this? I don't mind using a different control other than ListBox as long as it is available in ASP.NET 2.0 and as long as it can be bound to my db. I also don't mind using JavaScript (which I'm sure I'll end up doing for the hover effects). Right now I'm fooling around with subclassing the ListBox control but I've never subclassed a control before so I'm somewhat clueless.

In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.
I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.
In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.

I have a big problem...I have made a page has a Data FormView controland the insert template of this Formview control has DropDownList to allow the user to choose section (SectionsDDList)..and there's also another DropDownList allow the user to choose a teacher (TeachersDDList)...more infothe SectionsDDList get the section list from SqlDataSource control which the "Select Command" of is:"SELECT section_id,section_id FROM sections"the TeachersDDList get the teachers list from another SqlDataSource control which the "Select Command" of is:"SELECT teacher_id,teacher_name FROM teachers WHERE (section_id = @section_id)"finallyI want the TeachersDDList to be filled with teachers according to the selected section from the SectionsDDList...So,I enable the Auto postBack function of the SectionsDDListand add the next code for the SectionsDDList_SelectedIndexChanged event:TeachersDataSource.SelectParameters["section_id"].DefaultValue = ((DropDownList)sender).SelectedValue;be aware that both of the SectionsDDList & TeachersDDList have been Bounding to a column...and the problem I have faced is that:Exception Details: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.maybe you want to know the Stack Trace:[InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.]

I have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?

I am using .Net 3.5 in VS 2010. I would like to use a couple of radio buttons, that are bound to data, to control the Expand/Collapse of a CollapsiblePanelExtender.
I have found several threads on the web that suggest using JavaScript to control the CollapsiblePanelExtender with a RadioButtonList, but I cannot $find the control in the JavaScript.
I have also found several threads that suggest using custom radio buttons, but I don't see how to do the databinding for these.

I have a couple of user controls in an Ajax enabled page. Both controls are within TabPanels.
I'd like to be able to refresh certain items within userControl1, from userControl2.
I've added a public sub within userControl1 named "doRefresh" (that does what I need) but I can't work out how to reference it from userControl2.
Can anyone perhaps point me in the right direction with this?

I have a control that inherits CompositeDataBoundControl. Based on the values of the bound data, I create som dynamic controls. In order to preserve state, I need to recreate the control tree on every request(from CreateChildControls):
[code]....
The problem is that on postback the PaymentMethod object is null, so I have no method of knowing what kind of control to recreate. That means that the control state is ruined. If I hardcode the type of payment control to make, it works as expected:
UserControl userCtrl = (UserControl)Page.LoadControl("~/WAF/View/VisitControls/Shop/CreditCardForm.ascx");
dataContainer.Controls.Add(userCtrl);
userCtrl.ID = "CreditCardForm";
how I can find out what payment method is used, so that I can create the correct control on postback?

I am making some application in asp.net 1.1 in that I am displaying data in datagrid from database. In data grid first column is of check box and radio button and in the last column we have text box now thing is that when i click on check box crosponding textbox we fill some figure and at the end we press calculate button to get total. After getting total we have to press continue button to go next step
But suppose if some body remove that check the we should press calculate button or chnage some figure in the text box then we should press calculate button again to recalculate. for that i kept autopost back on check box oncheckedchanged event and text box ontextchanged event and hide continue button so user will click calcutae button abd then continue button will re-apper
Problem it that it taking too much refresh and taking long time. So was lloking for some ajax method to use in my application.
