View 1 RepliesA new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:
[Code]....
I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.
I was wondering, how about can i databind some custom attributes to my Radiobuttonlist / Dropdownlist / Checkboxlist? My existing code as follows:
With Me.ddlOtherApplications
.DataTextField = "ApplicationName" + Me.iSolutions_SysVariables.sys_iLanguage.Replace("-", "")
.DataValueField = "ApplicationID"
.DataSource = dtOtherApplications
.DataBind()
End With
However, I have 2 more additional custom attributes: ApplicationID and ApplicationImgUrl..... how abt do i databind these 2?
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 was woundering if there is a way to seach for a gridview on event handler.? I have three gridviews in which i can insert from and on my insertbutton codebehind, I want to check the gridview i am using so i could get the datakeynames for insert into the database.
View 33 RepliesI have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.
EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole =
new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi
is the webform code behind partial class.
CheckBox chk =
new
CheckBox();
chk.ID = _columnName;
chk.DataBinding += new
EventHandler(chk_DataBinding);
//Attaches the data binding event.
chk.AutoPostBack = true;
chk.CheckedChanged += new
EventHandler(ealmsapprole.Dyn_CheckChanged);
container.Controls.Add(chk);
chk.Enabled = true;
This is the code for the event Handler
internal
void Dyn_CheckChanged(object sender,
EventArgs e)
{
string err =
"";
try
{
if (lblAppID.Text !=
"")
}
that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.
I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.
View 3 RepliesI have a requirement to create our own MultiValueControls like CheckBoxList, RadioButtonList, DropDownList. I need a headstart, the usercontrols should have all the Even Handler implementation, setters and getters. Also,i will have a table which has the control properties(width, height, cssclass, etc) stored for that control. HOw to dynamically set the properties from the database to the usercontrol. This is required, because the requirement is for the Dynamic Form creation, I store all these ascx controls in the database and all the properties of the usercontrols in another table and map them dynamically.

I would like use radiobuttonlist with my FormView with INSERT/Edit buttons, I want once user selected one of Radio button in Radiobuttonlist, it should assign value to my database.For example I have 3 Radio button in Radiobuttonlist, if user chose option 1, then save in my database option1 and the other save it NONE. That mean I have in my database three field which they are (option 1 - NONE - NONE).I hope you get my point. I am still learning ASP.NET, thank you for your support.
View 4 RepliesThis seems like a simple concept, but I'm missing something major. I'm trying to populate a radiobuttonlist from a sql table (firuged that out). Now I would like the button selected that represents the last record.

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.
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.
New to asp. I'm trying to figure out how to populate a radiobuttonlist with selections from a table in a database. I honestly have absolutely no idea how to do. There will be different products in the database that need to be pulled to different radiobutton lists.

View 1 RepliesIn the website I'm building, I have a form that allows new users to register. Part of this page has mandatory address fields, and I use a postcode lookup field which returns a SuburbID and FullSuburbName (Suburb, State & PostCode) to a RadioButtonList inside an UpdatePanel.
[Code]....
I then handle the insert process in codebehind, and all this works perfectly on my New Account page.What I'm trying to do now, however, is replicate this functionality in the Edit Template of a FormView on my Manage Account page. The idea being that the user can view their current details in the ReadOnly view, then switch to Edit view to change their address (amongst other details of course). When the FormView changes to Edit mode, it should display the user's current PostCode in the textbox, and the RadioButtonList should display the available Suburbs for that PostCode, with the user's current SuburbID as the initial SelectedValue. If the user changes the PostCode and hits search, this refreshes the RadioButtonList with the new list of Suburbs, and once they have selected a new SuburbID this should get written back to the DB with the rest of the form (when they click Save I mean), using the SQL Data Source Update element. However, I simply cannot get this to work inside the FormView Edit Template and
So far, I have tried to handle the FormView's ItemCreated event and populate the RadioButtonList with the Suburbs that match the user's current PostCode, but if I do this with SelectedValue='<%# Bind("SuburbID") %>' in the RadioButtonList, I get the error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."If I then change it to have the SelectedValue populate from the codebehind, this works on the initial switch to Edit mode, but when the user changes the PostCode and hits search, I get a different error "'rblSuburb' has a SelectedValue which is invalid because it does not exist in the list of items."My thinking was that rather than binding the RadioButtonList I would just add the new SelectedValue in the SQLDataSource_Updating method, but it doesn't seem to like that either.
I have a Formview which contains a radiobuttonlist control in the EditItem template. I want to access the radiobuttonlist control and change the selected item client side using javascript.I've tried various combinations of document.getElemetByID and getElementsByName etc. but with no luck.Does anyone know to get to a radiobuttonlist controls in a FormView Edititem template using javascript?
View 13 RepliesI'm trying to bind an array to a radiobuttonlist following the example from this link: [URL] The main difference is that I am creating my array from a database... the array seems to be populated just fine, I can create a label from any cell of the array, but I just can't make a radio button list from the array.
