How can I print repeater data in asp.net? - c#

How can I print Repeater data?
I am having a Search page which makes search query according to the input given and populate the repeater. Now I want to print this result displayed in the repeater. How can I do that on the onClick button event of a "Print" asp:Button?

If you want to provide search capability, follow below steps-
If you are filling repeater on PageLoad with whole data, remember to prevent your repeater binding always on PageLoad using IsPostBack property.
Now on Click event get the filtered data, and bind it with repeater.
Hope this will solve your problem, If need any help please update your question with code.
Thanks.

Asynchronously update asp.net repeater as and when data changes

I want an asp.net repeater control to update by itself as and when the actual data that it's pointing to, gets updated. I'm not looking for a solution where a button click happens and each time repeater(which is inside an updatepanel) is bound to a datasource.
Ex: In my page load, I have this
Page_Load(){
myRepeater.DataSource = ListOfStringObj;
myRepeater.DataBind();
}
Now, if at some point ListOfStringObj gets updated, then the repeater should reflect the changes without explicitly binding it again to the datasource.
Is this even possible? I'm not particular about repeater control here, it can be a gridview as well. If not can anyone please explain?
PS: Something of this sort is possible using Knockout js, which is based on MVVM
Thanks,
Sharath
I hope this MVVM for ASP.NET will help you to achieve this: asp.net MVVM

Button List inside the DataList control

I am a facing a situation in which I need to use something like a ButtonList inside a DataList control.
Since there is no control like ButtonList, should I nest a DataList/Repeater inside the DataList or there is some other better option to handle the situation.
I am not exactly sure what you are looking for but this is what I assume you want:
YourListItem1
ButtonAction1
ButtonAction2
ButtonAction3
ButtonAction4
YourListItem2
ButtonAction1
ButtonAction3
YourListItem3
ButtonAction1
ButtonAction2
YourListItem3
ButtonAction3
ButtonAction4
Or something similar?
To produce this you could just have a DataList with a Repeater inside that contains the buttons you need. You could implement the OnDataBinding event of your DataList (YourListItem) and then bind the data that produces the buttons based on some data. Then in the Repeater you could implement each button's OnDataBinding event and assign the CommandArguments with the ID or detail you need to make the button act specific to the row it is on.
This method would allow you to make one function for each button used in your template and the CommandArgument would define the details of the action.

Dynamic Drop Down List ASP.net

How can I create a dynamic drop down list without using AutoPostBack. I ask because I just want to change the value of what the second drop down list displays and then the user clicks a button and it submits. But If I use AutoPostBack then it postbacks to page and runs code that shouldn't be run until that final box has been selected. (I use Postback in the other part of my program so using !IsPostBack isnt a option.) I looked at Javascript but ASP generates all of its controls names at runtime. What can I do? I have looked at the Ajax CascadingDropDown control but my problem with that is it contained in a XML file or a Database, I need this to be contained inside my Page. Any Ideas?
You can use the CascadingDropDown control from the AJAX Control Toolkit
Maybe this example will help? It's part of the ASP.NET AJAX Control Toolkit available here.
You can use AJAX to get the values for the second drop down list, based on the selected value of the first. Add a onchange event handler on the client-side to the first drop down list that makes the AJAX call and fills the second on success.

How to make listview items clickable in c#

I have a listview that is connected to a datasource. When I view the project in a browser, the listview is populated with data from the Northwind database. I just have the CustomerID and ContactTitle columns displayed. I want to be able to click on the CustomerID and then display the rest of the information about that particular customer. I've searched and searched and searched and tried a ton of different things but I just can't figure out how to make the CustomerID clickable. I am using c# and ASP.NET. Any help would be greatly appreciated.
You want to create a itemTemplate that contains various controls and bind the columns of your datasource to those controls. For the field in question you want to make sure you select a "clickable" control. like a link, button or even a div, and then create a handler for that click event. A good example of such a thing can be found in MSDN here: http://msdn.microsoft.com/en-us/magazine/cc337898.aspx
Do your list items contain li's? Whatever tag you use, you would use the javascript onclick event on each li to initiate whatever action you require.
If you need to retrieve customer data you could initiate a postback from your javascript to retrieve the data and display the customer details.

C# gridview nested in repeater update

My current situation is to display an unknown number of Plantypes and within those Plantypes display a list of Participants(also unknown number), the participants have a textbox and a dropdown that is editable (you can't edit the individual rows, there is one update that does a bit of validation then updates all rows.)
I currently have a gridview nested withing a repeater, the repeater displays the Plan in a label and OnItemDataBound I call a method to populate the gridviews. It looks great, but I can't figure out how to save all the data at once. I'm not opposed to handling this a different way, as in loose the gridview and or repeater, if someone has a better idea.
This is C# and framework 2.0...there is no sorting or paging on the gridviews...just some links and the fields to update.
thanks in advance,
Padawan
HTTP is stateless. Since a user physically can only update one record at a time you should implement some way to save as the user goes. This can be a simple as having a row focus and row blur events and do the saves using AJAX on blur(unfocus). Maybe make is modal as they edit so they cannot leave the page without saving.
