Forms Data Controls :: Unable To Identify On Which Row The Action Is Done?
May 11, 2010
I had a gridview with checkboxes in all rows.If I check one check box in the row remaing checkboxes in that row should also be checked and If I uncheck one check box in the row remaing checkboxes in that row should also be unchecked . my problem is I am unable to identify on which row the action is done(menas on which row the checkbox is checked or unchecked).In the Checked change event i wrote the code but i cant identify which row is checked..
I display a GridView where ther user can choose a Datarow with the select action. I catch the selection with the "SelectedIndexChanged" event of the GridView.
[Code]....
My problem is I can't use the SelectedIndex to identify the Access Row because when the user uses paging/sorting the SelectedIndex is not the AccessRow. Somehow I have to identify the selected row the user chooses with the PrimaryKey in Access ("Number").
I have a few textboxes,dropdowns and one checkbox in a DataGrid. when the checkbox is checked/unchecked i need to save the record.How to raise a event when a checkbox is checked/unchecked in a grid.How to Identify the row which is checked.
The goal is a facebook style interface where one users post can be commented on by another by clicking on a "comment" link. I am finding this some what difficult.
First - although I think that I will have to use a nested repeater, the initial issue is how to ID a text box that is embedded in the repeater.
I have a repeater control bound to a dataset. Within that repeater I have several further controls one of which is a dropdownlist. I trap the OnSelectedIndexChanged event of that dropdownlist because I want to recalculate some figures presented on the same row within the repeater.
How do I reference other controls which are on the same row of the repeater as the dropdownlist ? Is there an index property or other mechanism whereby I can identify the "current" row?
I have created an ASP page to display records for auditor review and response. The page consists of two repeaters that display 5 rows from a database at a time. for each row displayed, a RadioButtonList, containing two buttons is attached. If the second button is selected, an input text box is displayed to allow auditor comments.
My situation is that I cannot find a way to identify which row is being selected? When I select the Button that should enable the text box, I'm receiving the following error:
"Object reference not set to an instance of an object"
I'm just starting out in ASP coding and would like to know what I'm not doing right?
I originally have the question posted here, but I need as many eyes as possible on it.Essentially, I'm having issues redirecting to an action in mvc2 when working with JSON data. I post a stringified JSON object to an action and the action in turn redirects as needed. It worked previously when using form fields, but not when I'm posting JSON. To get posted JSON objects to properly bind to parameters objects in MVC, I'm taking advantage of the JsonValueProviderFactory class from MVC2Futures/MVC3Beta.Why is this occuring? The jQuery ajax call is telling the server "I'm giving you json, I expect html in return" and all actions pointed to via RedirectToAction calls are structured in a similar manner. I instead get stuck in a loop, continually hitting the originally requested action, with a prompt to reenter authorization information to boot! It seems lose authentication/authorization information in the process.The linked question on
I have a custom actionfilter that strips out the whitespaces before the html is rendered in browser and it is working fine. However I have been unable to unit test the custom action filter. Ideally I want to do an assert on the sample html that all whitespaces have been removed. Code looks something like this.
with a commandName="confirm" and its CommandArgument the memberid from objectdatasource. I have create a code behind to put certain action to the said button..

But it has no effect. Did I make some mistake? I'm still new in this ASP.Net things.
I'm making an Online quiz website using ASP.NET and am using a FormView to display the questions to the user and am using Radio Buttons for the choices.
1. How to store the choices that the user selects for the questions so that I can do the scoring at the end of the test ?
2. At the Quiz page, I'd like the user to know the questions he has attempted and those that he hasn't. How shall that be done?
I've a listview in which i'm binding data from objectdata source. I have a requirement where i've to allow edit/delete for only certail listviewitem which meets specific requirement. How do i dynamically set that some item can be only be edited not deleted thus only edit button/link should appear and vice-versa.
I have a UserControl (UC) which is in an UpdatePanel. When the UC is loaded, I run a recursive method to set tooltip for all Button, LinkButton, and DropDownList in this UC. The problem is sometimes I only update 1 control in the UC such as a DropDownList, but I have to call the recursive method on all controls of the UC. I was wondering whether there is any way to identify which controls is updated in the UpdatePanel so that I can update correctly these controls.
I have one controller with 4 to 5 action method. In all action method i have to check some feilds from database. So to reduce the database query i want to save this data one time and then want to use that in all action method.

i have the following scenario, i have a column of a gridview that shows me a text telling me is the user is allowed or not to access to some page, but now i just showing allow and deny, but i wanna show images that represent me the action, how can i do that?

i am still stumped with this operation: i am trying to retrieve a GridView selected row data..here is my code.. the commented part that gives me the selectedindex works just fine....but the one giving the selected row cell value does't work and there is no error.. The update operation is done successfully...weired. i need to assigned selected row cells values to variables ..do some calculations and then re-assign the result calculation to cell[9]..
