I 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 have been trying to do this all day but nothing seems to work. SOMEONE please enlighten me !!! I am adding products to a string and displaying them in another page. All is good .... up till here.
Now I have a problem when saving these strings (ie: the added products) into gridview. I tried using objectdatasource but I'm getting confused. Anyone done this before ? Basically when the products are in gridview I want the user to press 'purchase items' button, and the items are written to the database.

I've been strugglying with this for some time now and I cannot seem to find what I'm doing wrong. I have a gridview with a hyperlink field, so when the user clicks on the hyperlink it takes them to the next page but I want to store 2 field value's in session. I've tried it the url way but I get a "Input string was not in a correct format"
and for security reasons I dont think its the best way, the only other way is for it to be stored in session.
In my project i am binding a gridview from session and i want to make it editable. i handled the rowediting,rowupdating and cancelediting event as suppose to and at run time i bound my data to the grid cells in the rowdatebound like this
if (e.Row.RowType == DataControlRowType.DataRow)
{ RequiredPaper paper = (RequiredPaper)e.Row.DataItem;
e.Row.Cells[0].Text = paper.PaperDesc;
}
and every time i click on the edit link in the grid view the cell never turns in the edit mode so i can not edit it!
I have a dropdown list with sessions: Summer, fall, spring, summer Interim.
And also have a gridview to display hours of those sessions. When chose session from dropdown it displays the data related to gridview.
Gridview has the 'Edit' option to edit hours for each sessions:
[Code]....
When I edit let say spring and update the field it redirects me to main page but everytime it selects the data from summer).
What I want is? If choose Fall from dropdown and make edit(in editpage.aspx?id=..) and update the data, then it should redirect to main page but choose the Fall from the dropdown (Not summer)
I've read that you should write repeaterControl.DataSource = null to clear the items in the control, but it doesn't work. Does anyone have any tips or links to articles about this problem?
View 2 RepliesHow do I clear my formview after a record has been inserted or deleted? At the moment it just sits in the previous state with the same details in the fields, still with the Insert button. Either it would be good to drop the formview altogether (I have a grid view on the same page) or move into the edit mode for the just inserted record.
Also the same with the delete - the formview stays on screen with the deleted record details and the delete button still available - I know it has fired though as my gridview is updated.
I want to clear a datalist when I select a button and I have tried this:
[Code]....
When page load it is invisible. I have a button1 onclick make it visible and people can input data the press insert. I set it invisible right in Formview Insert eventhandler code.
When people click that button1 again to add 2nd record the form appear again as desired. However, the data from 1st record is still there.
What code I can make in eventhandler to make sure when button1 is clicked the Formview does not contain any data from last entry ?
The formview clear the data from 1st record if I did not set visible/invisible.
