I have a gridview with a linkbutton in each row. When I click the linkbutton it should update the status of a field from enabled to disabled. I am using a stored procedure to achieve this but i need to pass in a ApplicationID which i am retrieving from the gridview through the use of datakeynames. I am using the code below to get this value into a variable.
iAppID = gvApplications.DataKeys(gvApplications.SelectedIndex).Values("iApplicationID")
However when it runs it gives me the following error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

View 1 RepliesI have a gridview that has a radiobuttonlist ( YES/NO ) selections. but since you cant uncheck once selected, they are asking to add a clear option so that if they make a mistake they can clear it..
How can i do that within a gridview so that they can clear any mistakes prior to submission?
I have a loop checking all my radiobuttons to perform an update, so if i would like to be able to clear the selection as soon as the click on "Clear" so when they submit, that row shows as if it was never selected.
I have webform that is used to search for records and displays them...the form contains a dropdownlist, a textbox, a button, and a gridview...user select an entry from the dropdown, type in a matching value and then click on the button to add the entry into the gridview. All of these seem to be working just fine...however, the issue am having is this...after working with the first entry and users search for the second record, the gridview still maintains the entries from the first search. How do i go about resetting the gridview each time there is a new search? Here is what my code looks like.

I've got a big problem here with the ListView control. Basically I've got very basic code, yet it seems to break the control completely.
Here's the deal, I got a simple ListView using an ItemTemplate containing a hyperlink. Obviously the hyperlink has to lead somewhere after clicking, so the datakeys enter the scene since I need to hook up a hyperlink containing the Id of the record it's in as a parameter.
Normally this shouldn't be a problem, so in the itemcreated event I look up the link control and add the url using data foud in the datakeys.So far so good, this all works out fine.
Now this contains a number of records, too many to display on one page, so I decided to implement paging by using a DataPager, which is the way to get the ListView to support paging. This didn't work.
After a little tinkering around with the code, I found that if I didn't get any datakeys in the itemcreated event, that it all works fine. However, I need to use the datakeys or I won't be able to hook up a url to the hyperlink.
Basically, that one line of code completely kills paging. Commenting it out immediately sets things right, but that's not an option.
[Code]....
When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the
first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.
