Forms Data Controls :: Populate Controls By Clicking Repeater Row?
May 21, 2010
Still quite new to this ASP.NET lark. I want to populate a set of controls with data from a repeater by clicking the repeater row. I was thinking about setting the value of a hidden field to the id of the row then doing a postback, using the ID to look the values up from my backend. 2 of the controls i need to poulate are ajax cascading dropdowns, so I will need to do a postback and not just set them via javascript.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.
I have used the gridview in 3.5 framework to dispaly a report ,In grid view i have used an Image button as Edit,While clicking on that Edit Button The row data fields in gridview likename ,Address etc have to populate in the Textboxes (Not in the Grid view row I am giving entry form in the same page )all the textboxes must be in editable mode
I am not clear when do I want to use a webservice over a sqlDataAdapter for dataRetrieval. I want to populate a repeater control which I have been doing from a dataTable that I fill from a sqlDataAdapter. Is there criteria when I would want to use a webservice to fill my dataTable?
I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.
I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
Is it possible to populate the updated data from the database to a repeater with out refreshing the page and with out using an update panel? This is my requirement.I have an option to save Name & Age to the database
Name <*textbox accepts name> : Age <*textbox accepts the name> Save Button
At the moment I have a detailsview which displays read only data and I have a button also. What I want to achieve is a situation where a user can click a button which will convert that specific piece of data inside a detailsview into a pdf document.
