Forms Data Controls :: Maintain Gridview Paging And Radiobuttonlist
Apr 7, 2010
Currently i am developing a quiz using gridview. I provided users with multiple choice question using radibuttonlist. Everything was fine but when i navigate to the second page (Gridview paging) and back again to the first page, previous selection on radiobuttonlist was missing. How do i maintain the radiobuttonlist over gridview paging. I have been searching solution for days:(yet, din manage find a proper solution.
I have a two webpages,in my first webpage i have gridview with 8 pages(paging) and four coloumns.In fourth coloumn i have a link button to redirect tosecond webpage ,now i am in gridview 4 th page(paging) then i clicked the link button and move to second second webpage.
second webpage contain one button that will redirect to first webpage.if i come from second webpage to first webpage the gridview paging get reset.but i want to be on gridview 4th page(paging).
how can i maintain the selected checkbox value in the repeater when i do a paging to a next page? While i go back to the previous page, the checkbox value that i have selected is still remain?
when i sort the grid and it is display in sorted order and when i go to next page it will show data in default order. how to maintain sorting order duing paging
I am using pagination on datalist control. It is working fine without any issues. But I am not able to maintain the checkbox state while doing pagination. Looking for appropriate code for maintaining the state of checkbox.
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
I have a radiobuttonlist inside a datalist itemtemplate and i need to bind the radiobuttonlist dynamically from database I have tried to bind it inside itemdatabound event of datalist but it the result is always duplicated according to the fields in teh database.
for more information:
the database has two columns one for questions and the other is for choices , for the first question with id lets say 1 there are 4 choices, when the radiobutton is binded the result appears to be 4 times duplicated ?
I've been hunting for a solution to grab the radiobuttonlist when they answer that particular question. It varies for the number of questions, but only one displays at a time, but there could be a radiobuttolist or checkboxlist based on the question type. I was figuring I could do this easy in the row command of the gridview, but that hasn't worked out so well since I can't get the datarow for some reason.
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 Gridview that is populated from a data table, there are two additional template columns which are not bound (one checkbox and one textbox). I intend for the users to fill data in the unbound textbox and check the checkbox as needed. (there really is a good reason why the data is constructed in this way)
here is the problem, when the user enteres data into the textbox and hits enter, the gridview appears to postback, which wipes out the checkbox and the data in the textbox.
I tried setting the enable view state of the grid to false, that was supposed to stop postback but no luck. I have the enable view state of the textbox and checkbox set to true and autopostback set to false. but still no luck
so I need to either stop the postback or intercept the enter key in the text box and cancel the action, but that is a bit beyond me at this point
I need the following functionality in gridview1). Dynamic add rows2). facility to delete any row (mainly when add new row a link button shd appear with remove text)3). when we add or delete a row the state of other rows should be maintainedeg:- we have a gridivew with 3 textboxwhen we click add button a new row with three textboxes are generated along with remove link buttonnow after creating 3 4 rows i add text in all textboxes , then again i add or remove the row the textboxes must not get cleared
I use pagination for my datalist according to this link [URL].....
this is style of pagination
First 1,2,3,4,5 Last
when i run web site i see my datalist with pagination in webpage my datalist is middle of page when i click on page number 2 or 3 to see other page of datalist it reload page and go to top of page i should scroll until I can see my datalist again.
i want when users click on page number after that they see other page of datalist directly not top of page ..
I realized this has been asked multiple times before, but I still haven't been able to get it to work. I'm trying to export a Gridview to Excel without losing leading zeros. Here is my code. Add added the STYLE lines to try to fix the problem.
Dim attachment As String = "attachment; filename=Awards.xls" System.Web.HttpContext.Current.Response.ClearContent() System.Web.HttpContext.Current.Response.AddHeader("content-disposition", attachment) System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel" Dim sw As New StringWriter() Dim htw As New HtmlTextWriter(sw) gv.RenderControl(htw) System.Web.HttpContext.Current.Response.Write(sw.ToString()) Dim STYLE As String = "<style> .text { mso-number-format: ; } </style> " System.Web.HttpContext.Current.Response.Write(STYLE) System.Web.HttpContext.Current.Response.[End]()
I am using radiobuttonlist and textbox in the gridview. I need to do operations on radiobuttonlist so that it should reflect on textbox . this is to be done after gridview_rowediting event fires i.e when we can see "update" and "cancel" buttons. I tried like this,
[code]...
here default selected value is "0" given in source.
My problem here is when I am changing the selecteditem, the corresponding action is not done.
This was working fine and then I was tinkering around and I can't figure out what I did to break it. When I stepthrough the debugger, the for each stmt cannot read values from the radiobutton list or the textbox, it only show "" for each. I double checked the id names between the code behind and the markup.
I have Gridview inside that i have RadioButtonList,Which is working perfectly. It also bind correctly.
Problem is when user navigate page,the value which was slected in previous page is not apper again.
Gridview is enabled with paging.
I want to save data on SUBMIT button which is outside gridview. So when user clicks this button it should get ALL selectedvalue of radiobuttonlist inside gridview INCLUDING paging and save it to database.
I have tried following code on Button_Click but its not working properly.
I have a GridView that is bound to a DataTable containing questions. Each question has a possible score of 1 to 9 which is handled by a Template Field with a RadioButtonList databound to another DataTable (containing the values 1 to 9). This all works fine except as an added complication, some of the questions have an extra choice in another field. So the problem is how do I bind the second Template Field to a datasource that is dependent on the question. It's like passing a parameter to the datasource of the second Template Field, the value of the parameter being the Key Field of the particular row. Is this possible and if so, how do I do it
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.
i have a gridview which consists of databounds and dropdownlist control. When I press the Add Grid Row Button, it will insert a row. Now my question is, if the user selected an item in dropdownList in the firstrow and the user click the AddGridRowBtn Again which will generate the 2nd row, how would i maintain the selectedItem in the dropdownlist after postback?
I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.
