Dynamically Adding Controls To A Panel Within A Data Repeater?
Jul 15, 2010
I have a Data Repeater to which I need to add x number of images depending on their existence in the database.
I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.
The problem is that only the first image is being written to the datarepeater.
Basically I have a usercontrol that is setup to capture a persons education details. I want to have a button inside the update that when the user clicks loads the usercontrol below the previous usercontrol.
What I am trying to do here is I want to add the dynamically created labels in the Panel on the Webpage and not directly on the Webpage. My panel has scroll bars and thus when I scroll horizontally or vertically only the background moves whereas the labels are static to the page.
And some labels are even visible on the panel borders on scrollbars (some on the page outside the panel) which are suppose to be placed inside the Panel. So when I scroll either of the ways even the labels should move along with the background image.
So how can I make these labels stick to the Panel and not the Page? How do I do it?
I just don't understand how this is done. I've gone through several questions here and from a few other websites.
Basically, a company will be adding process steps, and I want there to be a textbox with a button next to it that reads "Add another step." Once clicked, a new textbox will appear beneath the current one, and the button will be moved next to the new text box. What do I need to do?
I've used <%# Container.ItemIndex + 1 %> to successfully add line/row numbers inside of a repeater control starting with 1, but I've run into a challenge where I need the line numbers to begin at row 50.
I have a repeater that has a delete button in it.When the delete button is clicked the panel updates and returns, then the row is deleted.So the deleted row stays in the repeater until i navigate away and then come back to the page. I commented out the update panel and all is good except i really want the update panel as the flicker is not pritt
I have a Repeater and an update button inside the repeater
[Code]....
When I run this databound control to wire a javascript function it clears the viewstate and I don't get itemcommands. When I remove the button attributes command it works.
[Code]....
Obviously I can find a more creative way to add the javascript function, but this was the clearest way. Can anyone determine why adding an OnClientClick even in the ItemCreated would cause viewstate to fail?
I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions. I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater.
I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there would be a big problem with memory.
What I am trying to achieve:I am trying to take the value of the selected index and depending on what this value is (e.g. the case selection in the code below) run a different query on the dataset and then create a repeater control dynamically to output each row with an item template that I can use css to style.
In other words: When a user choses a list item it shows only rows from the dataset that match the list item chosen. For example if a user choses Closed Tickets they only see rows from the dataset that have a STATUS of 'CLOSED'.
What I have done so far: [Code]....
What I'm struggling with at the moment is:
1) That the case selection works but the selection of the appropriate data from the dataset doesn't seem to be happening. And this data isn't getting stored in rows as I had hoped.
2) I'm not sure entirely how to display the dynamically created repeater control in the admin.aspx page.
I am trying to build a repeater dynamically through the code behind. I found this code on the microsoft site:
Protected Sub Page_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Repeater1.HeaderTemplate = New MyTemplate(ListItemType.Header) Repeater1.ItemTemplate = New MyTemplate(ListItemType.Item) Repeater1.AlternatingItemTemplate = _ New MyTemplate(ListItemType.AlternatingItem) Repeater1.FooterTemplate = New MyTemplate(ListItemType.Footer) Repeater1.DataSource = New String() {"one", "two", "three", "four"}
[Code]....
So this code works without throwing any exceptions, but what I would like to do is accessing the DataSource inside of Sub InstantiateIn(). I know you can access the DataSource in the front end using DataBinder.Eval and Container.DataItem, but is there a way to access the data during the InstantiateIn() Sub?
Or if there is another way to do this i'm up for trying that as well. Essentially I am trying to avoid writing asp.net code, instead I would rather write everything in vb (code-behind)
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 am using Repeater control. In DataBound event I am preparing output of item and everything works ok. But now I need to add a command button to item. I cannot add button to item template in designer (some project specifications do not allow it). I create new button at DataBound, set unique ID, command name and argument and bind it to command event and, thenm place it to Item controls container. It is not working as command button.
i'm using a repeater with an hyperlink and i'm displaying some data from a table x and when the link is clicked i want to add some from the displayed data in another table y..I used a datasource for selecting information , should i use another datasource for the insert command or what to do ..
I have tried binding images to repeater from one folder called images . But now, I am trying to bind the repeater with different folder's images, based on which menu item is clicked like "Wedding", "Birthday". When "Wedding" is clicked then it repeater should be loaded from Wedding folder's images similarly with "Birthday".
Currently i am using following code to load from single folder.
if { Repeater1.DataSource = di.GetFiles(); Repeater1.DataBind(); (!IsPostBack)string imgDir = Server.MapPath("~/images");DirectoryInfo di = new DirectoryInfo(imgDir);
I am creating a survey page that has a list of questions and answers that can be radiobuttonlists, checkboxlists or textboxes. These controls are added dynamically to a Repeater in its ItemDataBound event using Controls.Add.
I've managed to render the page ok but when I submit the form and iterate over the controls in the repeater to get the selectedvalues of the radiobuttons and textbox values, FindControl returns null. What do I need to do to get get the selected values? I've tried iterating over the RepeaterItems but that returned null too. I've tried different types of FindControl but it never resolves the control types.
It works if I add a declarative DataBinder in the Repeater like this
However, I want want to dynamically add the controls but in doing this i cant get the selectedvalues when submitting. This is tha main structure of my code...
I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
I've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
[Code]....
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)
