I am trying to bind a DropDownList inside a repeater control to an existing data set (to be able to edit the data) and I have been searching for an answer to this problem for a day and a half now without any luck.
View 19 RepliesI am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.
I also read this article [URL] but still can't understand how to bind dropdown in a repeater.
I want to display 2 things inside the Repeater Control.
1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.
2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)
Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.
Here is my code so far ....
ASPX Code:
<body>

Collection<ParameterDetailDTO> clParameterDetailDTO = objMonitoringDataInfo.GetAllParameters(idList, out errorCode);
var parameters = (from resx in clParameterDetailDTO
select resx.ParameterType).Distinct();
Repeater1.DataSource = parameters.ToList();
Repeater1.DataBind();
counter = Repeater1.Items.Count;
while (i < counter - 1)
{
foreach (var parType in parameters)
{
var items = from resx in clParameterDetailDTO
where resx.ParameterType.ToLower().Contains(parType.ToLower())
select new { resx.ParameterName, resx.ParameterID };
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataSource = items;
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataTextField = "ParameterName";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataValueField = "ParameterID";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataBind();
}
i++;
}
I am using LINQ as datasource.
I have a TreeView control inside a repeater control. I try to bind the data to it using this syntax but it errors out:
<asp:TreeView
ID="tvChainAccounts_Off"
runat="server"
Enabled="false" DataSource=
<%#DataBinder.Eval(((RepeaterItem)Container).DataItem,
"tvChain")%>
></asp:TreeView>
where tvChain is a property of type TreeView.
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate>
<ItemTemplate>
<!-- start child repeater --> Here I want to use one repater control <!-- end child repeater -->
</ItemTemplate>
</asp:Repeater>
I use DetailsView to insert rows in database. Row has fields id, subcategory_id etc. I want to fill dynamically dropdownlist ddl_subcategories, which is used in TemplateField. Selected item value of first dropdownlist ddl_categories is used as parameter for generating collection for ddl_subcategories. I try it with using UpdatePanel, but method DataBind returns error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.".
There's code of web form

I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see:
http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate
It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.

I can't create a dropdownlist inside repeater.
not about Dropdownlist item, i want to known how to handle OnSelectedIndexChanged attribute of the dropdown
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'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
I would like to display contents of two (or more) tables inside a Repeater control grouped by some Category. I will be getting the data in sepatare DataReaders (not a single joined query). Is there a way to do this without resorting to building DataTables/DataSets ? I am aware of nested repeater techniques, just not sure how to relate the data with DataReaders.

I have a custom page (Page 1) in SharePoint where I have a repeater control. From Page1 I open Page2. This is where I generate a collection of object which i use to bind repeater control in Page1. For the first time everythings work fine. If I have 5 objects to bind, repeater control shows 5 elements.
Now assume, I have 5 elements in page 1. When I open page two It carried over same 5 elements. I delete 1 element and send 4 element as collection to Page 1. In page 1 after I databind the repeater control, it doesn't display correctly. It deletes the wrong element.
I debug my code. The collection which i am binding to repeater shows the correct elements. But while displaying i is not showing correctly.

But now, I am trying to bind the repeater with different folder's images, based on which menu item is clicked like "Wedding", "Birthday".

How to create Grid view control inside Repeater control.
View 7 Repliesi am developing a sharepoint webpart. In this webpart i need to use a repeater control. The problem is, i can only use codebehind for creating and using the control. So i have some questions:
1. After creating the repeater control in codebehind, how to create some templates (itemtemplate, footertemplate, etc.) and use it?
2. How to bind a object collection to a repeater control?
I have a drop down list inside a repeater on a screen. I have no problems populating the list with all of the options at the time of binding. Everything works out fine EXCEPT the load time.
All of the options are there so it's fine. But my users would like me to fill the drop down list with the values at the time they click on the drop down list.
The repeater itself is inside an AJAX Update panel.
So I am trying to figure out how would I fill the drop down list with the actual values when they click on the drop down list inside the repeater inside the update panel?
