Set Previously Selected Radio Button Checked In Classic After Page Is Postbacked?
Jun 9, 2010
I have never worked on classic ASP and unfortunately i am supposed to modify an old classisc ASP web site.
ASP.Net ViewState does take care of maintaining control's sate automatically. How do i do it in classic ASP ?
I have two radio buttons and a text box placed on my ASP page, when user types in something in the text box based on radio button selection we display different search results. Now what i need is to keep the previously selected radio button as checked after the page is postbacked. How do i do that ?
I am selecting multiple dates on a calendar control ,, and then i insert them into DB. The problem happens after i insert, if i want to add new list of dates, once i start selecting on calendar all last selected dates appear (get selected on calendar) Does this mean these dates are saved in Session or what? Here is the code I am using:
how do i go about looping through each group of radio buttons and getting the text of the selected radio button ?the code displayed above is created dynamically ... in my aspx file i have the following code
I have a radio button list inside a repeater , the repeater is inside a Datalist.i need to get the value of the selected radio button. Also I need to select only a single radio in entire datalist using javascript.
I am looping through all the posted data on my website and grabbing the values, this will then be used later on. The user is going to put 2 radio buttons on the page, one with a correct answer and one with an incorrect answer. I need to know how to see if a Radio Button is checked or not based on the posted data.
I'm trying to add a css class to the parent div of my radio button if it is checked. Then remove if it is not checked. Using onfocus and onblur won't work on radio buttons for some reason. I also want to achieve this without specifying any type of id or name, just by the html control of 'input'.
I have 3 radio buttons op1, op2, op3 working as a group. In the code behind I check to see if a paticular button is checked, then do some processing. The problem is all the buttons return null. Checked in the debugger and all values are null even op1 which value is set to true.
I have added a template field in a gridview. In that i have added a radio button. I have written a code which will get row Id of GridView of a row which is having a radiobutton on it checked. Through code i am getting even name of that radio button, but it is showing me that radio button is not checked, even when it is already checked. Here is the code. Dim row As GridViewRow Dim rd As RadioButton Dim rowId As Integer = -1 For Each row In GridView1.Rows rd = CType(row.FindControl("radio1"), RadioButton) If rd.Checked = True Then rowId = row.RowIndex Exit For End If Next Even when a radio button is checked the code never enters the if block.
<asp:RadioButton GroupName="grpAssoc" ID="rbtEvery" runat="server" Text="Everyone" onclick="return doChangeAssociationType(0);" AutoPostBack="True" oncheckedchanged="rbtEvery_CheckedChanged" /> but oncheckedchanged="rbtEvery_CheckedChanged" not firing even javascript function returns true
i have a view wich gets in its model (among other things!) a string with the name of partialView to be rendered in a certain div.
well, in that partial view there are two radion buttons, with the same name but diferent id's and values.
when i submit the form in the view, wich also has the partialView controls (radio bts), in the respective controller i get inside a formcollection an item with both values of the radio buttons,
my question is, how can i find wich one was selected in the view?
i have a web page in which i place radio button list, when i select any radio button, on printing i get light color for selected radio button, how i get selected radio button dark colour so that it can visible easily..
I'm trying to sort records in the gridview right after a radio button is selected. My approach is with the dataview, but because the dataset variable doesn't survive a round trip to the server, I don't know how to make this happen.
Public Sub GetCustomers() db.RunProcedure("usp_customers_get_all") db.doSort(radList.SelectedValue) gvCustomers.DataSource = db.MyView End Sub Protected Sub radList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles radList.SelectedIndexChanged If radList.SelectedValue = 0 Then db.doSort(0) gvCustomers.DataSource = db.MyView End If If radList.SelectedValue = 1 Then db.doSort(1) gvCustomers.DataSource = db.MyView End If End Sub Public Sub doSort(ByVal strIn As Integer) If strIn = 0 Then MyView.Sort = "lastname, firstname" Else MyView.Sort = "username" End If End Sub Public Sub RunProcedure(ByVal strName As String) Dim objConnection As New SqlConnection(mstrConnection) Dim mdbDataAdapter As New SqlDataAdapter(strName, objConnection) Try mdbDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure Me.mDataset.Clear() mdbDataAdapter.Fill(mDataset, "tblCustomers") MyView.Table = mDataset.Tables("tblCustomers") Catch ex As Exception Throw New Exception("stored procedure is " & strName.ToString & " error is " & ex.Message) End Try End Sub
I have a Gridview with Radiobutton selection and two text boxes and two buttons.
What i need is to like search and extract functions.
My Gridview Initially contains all the data in the table. In one text box, like if i want to search "Learning" in column FIRST NAME and i type "L" in the text box and click the button, all values from the column FIRST NAME starting from "L" should be listed in the Gridview, so that from there user can select "Learning" and click another button to extract values corresponding to it in the another Textbox.
I'm trying to figure out how to access controls that are added to a panel in a code behind file.For example, when I click a button, I add a radio button list to the panel.How do I access the selected item from that radio button list? I get an error saying it is not defined, even though list gets generated..
I have a table in my form, where I put n-rows, every row contains 1 RadioButtonList, when user select the item in RadioButtonList, I need to get the index of selected Item, without updating the page
i have a grid view with radio button...schedule/approve/reject...by defualt schedule radio button is selected....but when i chage radio button selection option to anyth other than schedule it still store only schedule in DB.wats the pblm?
[Code]....
[Code]....
when i click submit button i got this 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.
so i set the enableeventvalidation=false
now i dint receive any error but when i set breakpoint on the funtion which called on buton clik it still got the value as scheduled for the radio button..spent almost half day for this.. all this while this was workin after i add the moralpopupextender am facing this pblm...now i tried removin that extender but still pblm exist.
I'm having a time finding out I could not do something simple as :
On the onchange event getting the new selected checkbox, this with jquery.
The checkboxes are located in the following div :
[Code]....
This all located in a form, when I will find out the selected radio on change I will post the form and use the value of the hidden field to know the selected radio button. Nothing really difficult.
Since setting item.selected to true will lose the mutual behavior and setting list.SelectedValue (readonly) doesn't get any button selected.
I am using list.SelectedIndex to assign the selected button. as follow :
//step 1. find the item by value ListItem item = list.items.FindByValue(obj.ToString()); //step 2. find the item index list.SelectedIndex = list.Items.IndexOf(item);
I make it into an extension method. But feel stupid about this procedure to simply just assign a selected value. does anyone have a better approach?
I have two pages ,On click on one button I have to redirect the screen to another page.and after clicking on redirect button page will get redirected to old page.
Problem: while coming to old page i have to set one radio button selected amnog two.I have acheived it through session.But the problem,is after coming back once i selected the radio button which is not selected. its not firing the selected index changed event.
I'm learning asp.net and c#, and can't figure out why this won't work for me.I'm using a label control and a radiobutton list control. Basically if you select radio button 1 I want the label to say radio button one , radio button 2 for the next one and so on. Here is the code I thought would work.
