Forms Data Controls :: Conditional Control Based On Repeater Content?
Oct 8, 2010
I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.
My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processedafter the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.
Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.
Is it possible to somehow output some content based upon some conditional check in Razor? If not, I hope this possibility will be added in the future. What I want to do is the following:
In my repeater I am attempting to set the label format based on a value from my datasource. The following line from my repeater is straightforward enough but now how would I modify it if I wanted the "C2" statement in the ToString to pull from a field in my datasource named "MyFormat" which would contain either the C2 or N0 value? Basically switching the formatting for that label between currency and a double?
I want to add a class to a div inside my repeater control based on whether the query string value is true or false, so that I can style it differently.
I have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?
on my repeater i builed a table and want to show a colum just for user that is in role admin.i need to remove the column in the HeaderTemplate and in ItemTemplate.i could use data logic and add a db column that will be boolean, but then i need to send to the SP the user role.
The Listbox has a list of students. The Gridview has a list of classes offered during a period, such as:
Math Science English etc. When I click a student in the Listbox, I call a sproc via Linq, and get the ClassID and ClassTitle that student is registered for.
What I need to do is Highlight the record in the GridView that matches the ClassID or ClassTitle returned by the sproc.
Previously, I used a ListBox for the Class Offerings. This is easy with a Listbox using the FindByText method:
My plain texts are image links and pdf URLs from a database table, in groups, in the correct order but I'm not sure how to render them correctly (sample image below shows what I am trying to render)
Is there any way to make a repeater template intelligent enough to render an "image link" OR "pdf link" based off the [type] column returned in the record?
table: pk Name Type (image or pdf) URL Description URL_Thumbnail (if image) GroupId (associate these records to each other) OrderNumber (order of these records within their GroupId)
I have created a backend that allows me to update my site content. I am using fckeditor to pull the data from my table in the database. The problem I am having is this: i need to create paging of content so that when the height restriction is met a next btn or numbering system displays to allow the user to click to the next page of content.
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 need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void

I have repeater control on page which bind with sql data source.i have dropdown to filter the records of repeater on button click event it refresh complete page i just want to show a wait message to user and just refresh repeater data instead of complete page refresh.i do not want to use ajax update panel.
I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.
[Code]....
txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.
I have a code behind page with two functions that return two counts (iCount and iCount2). In my repeater table I can display the results of the functions just fine, but now I need to do some conditional logic based on the results of the functions, eg:If iCount =>3 AND iCount2 =>1 Then
