i have the following problem. i'd like to use a listview with paging for mulitple selection of items in a list. The selection is no problem. I do have f.i. a list which holds the key values.
List<Int64> selectedList = new List<Int64>();
As soons as the user makes a selection or removes a selection the list will be updated accordingly. Also hold this list info when changing pages of the listview.
[Code]....
This list can be stored either in a session or a viewstate.
My question is how can i retrieve the information of the list back into my listview and thus displaying the selection the user has made when he jumps from page to page.
how to do this when the checkbox in listview layout template check select all checkboxes in listview itemtemplate.I dont give 'Eval 'field to checkbox present in itemtemplate.
I've a list box which may contain 300000 or more records. I've another listbox . The user basically selects from the first listbox and adds to second lbx. There is button which when clicked will move the selected records from first listbox to second listbox.
Now if I select around 45000 records and try to move to second listbox .. it moves fine . If I select more than 45000 or so...it takes very long and eventually i get the "Action Cancelled". When I put a break point in page_init ..it does not hit. Is there a way I can restrict the user by selecting more than 40000 items. ie they should not be able to highlight more than 45000 records.
I have a dataTable that contains a specific column from a database. A listbox contains 100 list items in it. When page loads, I need those listbox items to be selected, whose value matches the value in the datacolumn of the datatable.
Following is the code i tried, but is not working. For some reason, it selects only the last item in the datacolumn.
if (datTableRelatedSchool.Rows.Count == 0) { } else { foreach (DataRow row in datTableRelatedSchool.Rows) { foreach (DataColumn myCol in datTableRelatedSchool.Columns) { lstRelatedSchool.SelectedValue = row["RelatedSchoolPK"].ToString(); } } }
So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
have trouble with grid view,I want to select specified items and show them in labels or text boxes.I don't want to use check boxes ...E.g:I want to use for or foreach methods and show all the items in column (1) in text boxes respectively.
I have checkboxes in one column of listview and outside the listview I have one dropdown and one button.
when I dont check any checkboxes in listview fire a validation "Select any one checkbox" on button click.
simirarly when I check Checkboxes in listview and I'm leaving to select dropdown fire a validation"Select any item in the dropdownlist" on button click.
how to validate both controls(checkboxes in listview and dropdown) when those are not selecting.
I'm trying to create checkboxes inside Listview from code behind, but I'm having problem creating them.
What am I missing here?
Checkbox's ID comes from Datareader.
Here is my code.
If reader2.HasRows Then While reader2.Read Dim jobid As String = Convert.ToString(reader2("JobTicketID")) Dim jobtitle As String = Convert.ToString(reader2("JobNickName")) Dim item As ListViewDataItem For Each item In ListView1.Items Dim jobtd As HtmlTableCell = CType(item.FindControl("jobtd"), HtmlTableCell) Dim jobtr As HtmlTableRow = CType(item.FindControl("jobtr"), HtmlTableRow) Dim cb2 As CheckBox = New CheckBox cb2.ID = jobid + "cb2" cb2.Text = jobid + IIf(jobtitle <> "", " (" + jobtitle + ")", "") jobtd.Controls.Add(cb2) jobtr.Visible = True Next End While End If
I have a listview with paging.Every paging has 10 rows with with a username, an email and a checkbox.
I need to be able to check a couple of checkboxes, in different "pagings", press a button and send an email every to ever user that has been checked.
Trouble is I don't really know how to remember the selected checkboxes between each paging-press.
Deos anyone have a similar solution or a few tips on how to do this? I'd prefer to solv this without jQuery, but ordinare javascript or a C# solution works fine.
May be I'm trying to run before I can walk, but here goes, I find coding for ASP so frustrating it's just not logical JIM!Anyways after my rant, as I'm a huge fan of the listview control in WinForms I'm trying to get the hang of it in ASP, wth not much luck so far.
For some reason, I get an error half way through cycling through my items in a listview right before a record that has a null value for one of its items. It doesnt' haappen any other time. It happens after completing one cycle of the onItemDatabound eventfor a record in a row that is immediately before a particular null value in record immediatley following.My code is written to look for the proper edititemindex, and if it sees it, then it checks for null values for all the items. I can't even get that far, it errors just before the onItemDatabound even runs for the correc edit index
I have checkboxes in listview item template and one checkbox outside the listview.when I check checkbox(outside listview) that should be validate all checkboxes in Listview.
I know this not the right place to ask javascript related questions.
But I dont understand how else to get the answer.
I have built an application using asp.net 4.0 and entity framework. I have implemented the routing feature introduced with the .Net 4.0 version.
Now, I have a page which will fetch products from the database and display them in a listview. For the paging purpose I have used the DataPager.
I had a really hard time making the paging feature work with DataPager as it is not fully compatible with the Routing feature(asp.net 4.0).
Now I want to give the user the option to select multiple products to compare. For this purpose I have placed a checkbox with everyproduct.
Now the problem:
I dont know how to find which checkbox was selected. i want to find the checked checkbox using javascript.
I have binded the list of products to the listview at two occasions; once directlly to the listview in page load and second time during the pre_render event of the dataPager. (As I said I had a really hard time to get this combination to work; Listview+DataPager)
I'm trying to check dynamically generated "checkbox" value inside Listview.
I can reference non-dynamic checkboxes exact in same location (index) inside Listview using "e.Item.FindControl", however I can't reference dynamic checkboxes.
Should I use the SQL Server bit data type or a simple varchar where the user would enter "yes" or "no"? More importantly, how wold I go about checking these checkboxes in the listview based on the values stored in my sql server database?
I have a ListView control in Asp.Net WebForms which display a set of elements, I have at the end a "More" button like Facebook for example. During the postback I want to get from database another 10 elements (I have already displayed 10 and I don't want to retrieve them again)
Something like this.
foreach (var item in New10Items) ListView.Items.Add(index,DataItem)
the problem is with DataItem, how to Bind it before add it? what is the best way of solving this?
I have a listview showing images like ImageViewer and I want to implement Drag-Drop behavior within ListView. how can i achieve the Srag-Drop inside the below kind of customized ListView.
I'm currently using a ListView in my webformsapplication. This ListView generates a table with (currently) three columns. "Username", "Organization" and "Locked". These are represented with string, string and checkbox respectively. The checkbox should postback on change...
Should I use <%# Eval("Username") %> or <asp:Literal blablah> to inject the data? This is more relevant for the checkbox... It seems very "dirty" to write <input type="checkbox" id="something" <%# if ((bool)Eval("Locked") == true) /* some unknown code for outputting "checked" */ ;%> />
