Forms Data Controls :: Conditionally Create A Hyperlink Within A Repeater ItemTemplate?
Dec 12, 2010
using a repeater to display multiple 'comments' related to a parent database entity (a 'task' in my case). When the user creates these comments they can optionally attach a file. Now, I'm working on the page that lists these comments and I'm not sure how to go about displaying the link to the attached file, if one is present. There may not be a file. The database record that contains the comment will also contain the url to the file if one was attached.
what are my options for this? I would like to just display a link to the file after the comment content, only if a file is available.
I have a Repeater displaying some data that doesn't do what I'd like to see. If a certain condition is met (ex: parent.NumOfChildren > 0) I would like a hyperlink shown. Here is what I have so far:
In this case, the "View Children" link shows up for every item in my Repeater, but I'd like it shown only if parent.GetNumOfChildren() > 0. Would it be correct to try setting the Visible="true/false" property of the HyperLink? Is that the norm for this sort of problem? Or, is there a way to wrap the entire <asp:Hyperlink> ... </asp:Hyperlink> tag in an if statement that has a reference to the object that is currently being interated in the Repeater? Ie:
In my application I have successfully pulled some rows from a database into a DataSet and then used an ASP.NET Repeater Control to create a div container for each row with each field contained within a span element as follows:
My problem is that I want the .png graphic link to have a onclick event so that a new div is dynamically inserted under the div to show data from a seperate database table. However since its all declared within the ItemTemplate then targeting the correct div using the JS DOM would be difficult/impossible as the id for each of the divs will be the same.
If this is going to be infeasible then what is the possibility of having data brought in from multiple tables would I have to manipulate the DataSet to include the extra columns as I think Repeater Controls can only have a single DataSet (corret me if i'm wrong).
I have a DataGridView with a ItemTeplate column, which has a HTML hyperlink (<a href....>) inside. When a user clicks on a link, a popup with a TextBox is showed to the user. Then the user can type a data. With this data, I must update the hyperlink's text in which the user clicked. All using javascript. The problem is that I don't know how to find the Hyperlink because there will be so many hyperlinks as rows in the DataGridView and they will have the same Id.
Above is the field in the gridView. My question is very simplet that whatever the number of rows in a grid in one column, I just want to show the sum of the values of a column in the Footer Row.
I don't want to use javascript. I have tried following code but there is displaying "0" in the footer of the respect column instead of sum.
[Code]....
I need assistance in the code which I provided. I want something like this:
I have tried many different combinations to try to get this to work, but I cannot. In the ItemTemplate of a Repeater control, I have a <form> tag. For this third party button to work, each button needs to be surrounded by <form></form> tags. I cannot get the first iteration of the repeater to display the tag, but 2, 3 and beyond, it will. It doesn't make sense to me. Because of this, IE is displaying the page in a funky way.

I have a repeater bound to a datasource that servers as a list of birds. When the user clicks an item in the list the bird's image is displayed on the page. I want to change the background color of the item that is currently selected in the OnClick handler for the main item in my repeater's ItemTemplate.
I have changed the styling of controls prgrammatically before and it worked fine but in those cases i used the ID of the control to directly access it in my code behind file. But since this is some arbitrary item in a repeater I don't know it's ID at runtime, all I have is the sender object passed to the control's OnClick handler. So in my code behind file, I tried casting the sender object passed to the OnClick handler to the appropriate type and used Style.Add("background-color", highlitColor) but it failed to change anything.
I had a thought - maybe this sender object gets passed by value so all I did was change the Style of a COPY of the control item.
If this is indeed my problem, how do I start with a casted sender object in an event handler and get a reference to the actual control in order to change it's Style?
I query the database to get the VideoName and VideoURL of the videos held in my database (Videos saved on the file system with their location stored in the database) then bind the query results to a repeater with the following code
and put a hyperlink into the repeater to list all the VideoName's this works fine but I want to pass the VideoURL to the next page I am using NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" but when I try and load the Page I get the error saying The server tag is not well formed. the whole repeater code is
i have a a public property in my masterpage, I have a repeater on another page which has a hyperlink, when i click on it, i need to give the masterpage property a value based on the hyperlink clicked. How do i go about doing this, because at the moment the property is set to the last value in the repeater. I have something like this;
when I loaded the page, the numbers come fine, but the links are not evaluated well: Instead of linking to Vacancies.aspx?VID=170 for example, the link comes this way: [URL]
I want to create C# code that checks a hyperlink in a repeater and checks if the file exists. If not, the hyperlink is not visible. The path and document ar pulled from a sqldatasource:
I have a repeater control that is getting exported to excel. Well excel will no longer show the data that was in the textboxes. I've read the article on exporting a gridview having the same problem and how you replace the texboxes with literal contrls. I was wondering if there is an article like it only for a repeater control.
I am trying to use a repeater control that will display a hyperlink control. For the text of that Hyperlink control I would like to concatenate to fields from my data source (lets say First Name and Last Name). How would I do this appropriately for the Hyperlink control within an ItemTemplate?
The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" > <ItemTemplate> <% If Eval("Item_Batch") = 0 Then %><tr><td></td><td colspan="2"></td><td></td></tr><% Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
