C# - Replacing Link Button And Label With Check Boxes / How To Pass Argument To Checkbox
Nov 26, 2010
This is my repeater in GUI and code behind ..I need to replace the 'Make Default' linkbutton with a Check Box now. What I want to do is that When user Checks the checbox, the Default value is set to TRUE in DB , Also when a check box is Checked, it will be grayed out..
NOW I was just trying to implement this but there's no CommandName attribute for checkbox and not even CommandArgument attribute!!
How do I change my code now ?
All I wanna do is replace that Link Button with Checkbox. Somebody his..How do i pass arguments to this check box ..I need the command arguments for my "SetDefault" method that sets the address to TRUE if Default is selected
[EDIT]
I am not getting it..in my Link Button now I am passing 2 command arguments like this CommandArgument='<%# Eval("UserID") + "," + Eval("IsB") %>' Now how do i pass these two Comand arguments that I need for my SetDEfault method in checkebox!? ok i got it that we use OnCheckChanged event when its check box and ItemCommand event is used when its link button...I am just not getting how will I pass these two command arguments in my checkbox
[EDIT]
Do I need to pass these two command arguments via text attribute ?
well i am new to Grid View , so i am taking a simple scenario. well i have a visual webpartin sharepoint ; i have added a grid view with first column is of CheckBox Type & it has a Button & aLabel
i populate the grid view from an array of cities & i want that when button is clicked all the checked cities are appended in to the label. code is below.
[code]....
while working i found that when button is clicked the page_load function build the grid view again & there fore all check boxes are initialised .
complete my code !!!!!
i do not want to do the same by using Javascript. i want to do this by C# only
& if possible tell me the way how can i put a checkbox near "Show" button that is used to check all the check boxes.
I have a grid view control with Template Field containing Item Template as Checkbox control and the Header Template is containing the label with column header name.
I want to click the coulmn header label and all the check boxes must be checked once.
provide me some examples or ideas how i can achieve this
when we select a check boxes creat dynamic check boxes. I have a main catagory check box when we select this main catagory check box creat subcatagory check boxes related to main catagory dynamically.
I have a datalist and the following link button within the datalist:
[Code]....
I would like to post to a new page and then capture the value from the link button (commandArgument). It appears from other threads I've seen that you have to rebind the datalist in order for the ItemCommand event to fire...is this true? I'd hate to make another DB call to bind my datalist just to make an event fire.
I have a gridview. The fields are displayed in table in itemtemplate. Each row has a unique id called UserId.There is a linkbutton for Editing in each row.
When the Edit linkbutton is clicked, I need to get the details in that row to another page. Is this done using querystring.
I have a datagrid control, the first column is Revno, currently presenting info in linkbutton. i want to do a condition based on another field docid, which gets true or false value from database. if true then present Revno in linkbutton otherwise show the revbnno just as a label., thatway users does'nt have ability to clickit.
<ItemTemplate> <asp:LinkButton ID="lblRevision" runat="server" CssClass="Textboxes" Text='<%# DataBinder.Eval(Container.DataItem, "RevNo")%>' CommandName="FileDownloadRecord"></asp:LinkButton> </ItemTemplate> this docid field has flag true or false. if true meaning show the revno as LinkButton, otherwise show the revno as label. GetDocdetail(DataBinder.Eval(Container.DataItem, "Docid") on the codebehind side i can use this function. Public Function GetDocdetail(ByVal DocID As boolean) As String If DocID = "true" Then Else End If End Function
I want to be able to have it so that each LinkButton can pass through an ID from the database as an parameter into the AcceptWager function and then I will do with it from there. The sql column for the ID is WagerId. It is returned in that query that i execute, so it is already in the reader.
I have a report and some of the Boolean fields (both in form- and gridviews) should be displayed as check boxes (what else). Then my client calls me and says "Hey I can change the checkboxes before I print the report, what is up with that?" What is up with that, indeed? . So I check this out and everywhere I go I read the same thing, you can "disable" your checkbox, graying it out (which nobody, including me, wants) or you can create workarounds to stop the behavior and I found plenty of workarounds. The posts I have read were, I'll admit, pretty old so my question is this: "Am I missing something or do I still have to write a workaround for something so fundamentally basic that it should not even be a consideration, let alone an issue. I mean if you stick a check box in a read-only element (form- or gridview itemTemplate) it should not be editable by default, right?
Cannot find a simple example that will call POST a service with username pass argument.
So, how to get the length of the service.
Code: Dim encoder As ASCIIEncoding = New ASCIIEncoding Dim data() As Byte = encoder.GetBytes(rawresp) Dim request1 As HttpWebRequest = CType(WebRequest.Create("http://www.sas.gr/MobileService/MobileService.asmx?wsdl&op=getCinemaMoviesProgram"), HttpWebRequest) request1.Method = "POST"
[Code] ...
Complains about wrong bytes. I can make it work with GET but i only get the schema.
Code: Dim request = DirectCast(WebRequest.Create("http://www.sas.gr/MobileService/MobileService.asmx?wsdl&op=getCinemaMoviesProgram"), HttpWebRequest) request.Method = "Get" ' request.ContentLength = 0 request.Credentials = New System.Net.NetworkCredential("WSl", "WSs") Dim response1 = DirectCast(request.GetResponse, HttpWebResponse) Dim reader = New StreamReader(response1.GetResponseStream()) Dim rawresp As String rawresp = reader.ReadToEnd()
This will only give the schema back, no data. Also if i reference the service there is no getCinemaMoviesProgram function to call, so I suppose it only works with post.
I have used check box in gridview . Now i want to validate those checkboxes as if no check box is selected a message should pop up saying select check box and thn press submit.
I am learning CSS in asp.net. I do not know how to make align for check boxes and labels. For example, below are six check boxes and six labels. How to make layout like below using CSS?
I am getting the following error on on clikcing checkbox from checkbox list in my project.
Error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
If i set <pages enableEventValidation="false"/> then on clicking the submit button the information is not saved in database just page is refreshed.
aspx.cs file code:
protected void btnSubmit_Click(object sender, EventArgs e) { if (con.State == ConnectionState.Closed) { con.Open(); } SqlCommand cmd = new SqlCommand(@"insert into MainTable values(@CollegeName,@AffilatedWith,@CollegeType,@Country,@City,@State,@EstablishmentYear,
protected void Page_Load(object sender, EventArgs e) { for(i=0;i<5;i++) { Textbox tbox = new Textbox(); tbox.AutoPostBack =true; tbox.TextChanged += new EventHandler(tboxevent); //Here I need to pass 'i' value to the tboxevent } } protected void tboxevent(object sender, EventArgs e) { Label1.Text = "i value"; }
