Vb.net - Dropdownlist Callback Doesn't Work Inside Div?
May 25, 2010
I have a callback handler done in VB which works fine with this code:
<!-- Div Outside Form -->
<div class="container">
<form id="querydata" runat="server">
<asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler">
[Code]....
It the postback no longer works. Is how asp is supposed to work? Or is it some magic error that only works for me? And most importantly, if asp is not supposed to work this way, how should I be doing this?

I have the following code:
<input type="text" ID="JOB_CODETextBox" runat="server" value='<%# Eval("JOB_CODE") %>' readonly="readonly"
onclick="$('#basic-modal-content').modal(
{
appendTo:'form', persist: true,
onClose: function (dialog)
{
document.findElementById('<%= JOB_CODETextBox.ClientID %>').value = 'value';
$.modal.close();
}
} );" />
The problem is, the binding '<%= JOB_CODETextBox.ClientID %>' doesn't work, it returns the same binding expression after renderign instead of replace it with the actual client id!

I searched all day a solution to my problem.I worked with MVC 2 with visual studio 2010.I want to bind dropdownlists according to the value selected in an other dropdownlidt (but the datas are not linked in the database).In fact, I have a function in a controller and I tried to call it thanks javascript. But during the debug, it never goes in this function.If I'm not clear, ask me some question.

I have an asp page that has an iFrame. In the onload event of the iFrame, the javascript code copies the content of the iframe to the div. The iFrame has src="test.aspx" and hence displays the content of the test.aspx inside the div.Test.aspx page contains and imageButton, which does not show up in the iFrame.I am getting the following issues:1. the image does not show up (cannot see test.gif)2. When i click on the imagebutton link, it tries to search for test.aspx in the directory where the asp page resides inside of the actuallocation/directory of the aspx page.

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)

Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
UpdatePanel2.Update();
}
Why paging causes gridview to stop working correctly? What can I do?

although I've searched already, but here is the thing:I have a ModalPopup wich have a Textbox, a Button and a GridView inside. The Gridview is binded to a SQLDatasource object, and the Select query is something like "SELECT field_1, field_2, field_3, field_4 FROM Table_Name WHERE field_1 LIKE '%@Parameter_2%'".This ModalPopup is used (or gonna be used) to search for a field, so the parameters received by the Query is the text inside the Textbox, I've linked thid inside the SQLDataSource Wizard.The problem is that everything works perfectly fine... inside the panel WITHOUT the ModalPopup Extender, but whe I add the Extender the filter function doesn't work.Here is my code:
[Code]....
Notes: I have a ScriptManager inside the MasterPage, so I don't have to insert one in every page. Also I've tested the code in a new page (the one I use for testing), and it works fine, it filters and everything, the problem is when I add a ModalPopup to the panel.

I have a Radtreeview that sits inside a RadGrid. For some reason the expand/collapse buttons of the Treeview are not working. I can expand the Treeview initially, however the NodeExpand event never fires.(a postback does occur to the server, and I have several buttons on the treeview node that work.) Once the node has been expanded, the collapse button doesn't work, and clicking on it does nothing.(no postback to server). I have the ExpandMode set to ServerSide. However, if I change the Expandmode to Clientside it works properly.
I really need the control to work with ExpandMode set to serverside, to reduce the loading for large Tree's.
Im not sure if this matters. But I am adding the Events to the RadTreeview when the event RadGrid_ItemDataBound is fired.I am noticing one strange behavior, that I cannot explain either, if I do not attach an event to NodeExpand It fails to open or close. Also the NodeDataBound event fires successfully and the data is loading fine into the tree.
RadTreeView tree = (RadTreeView)e.Item.FindControl("RadTreeView1");
tree.NodeDataBound += new RadTreeViewEventHandler(RadTreeView1_NodeDataBound);
tree.NodeExpand += new RadTreeViewEventHandler(RadTreeView1_NodeExpand);
tree.NodeCollapse += new RadTreeViewEventHandler(tree_NodeCollapse);
Here is the decleration of the Treeview in the ascx file

<telerik:GridTableView Name="Detail Table" ShowHeader="false">
<Columns>
<telerik:GridTemplateColumn UniqueName="FooTreeview">

I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:
[Code]....
This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?

When I change the value in dropdownList (in browser), it does PostBack, but it selects the first item of list after PostBack - it doesn't save my value.
GetAllDepartments(isDeleted) is a stored procedure, it returns a List of objects with two properties - FieldKey and Name.

I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these
