that I would like to be always, on page load, to mark the first option ("no expiration date"). However, if the user marks the second option and reloads, the second option is selected, even though I do this on page load:
II am populating a radiobuttonlist in code on page load, although not when postback is true (I've checked this by the way).
Autopostback is set to true, viewstate is enabled (everywhere I can think of, although only in the content page, if that matters)
When I select an item, the postback happens, the populating does not happen, and the selection reverts back to the first item, which was never selected.
Nowadays I have the knowledge to do this in javascript, but I would prefer not to. It can't be that it should work like this, can it? The control would be useless. I want the index that is selected.
in my asp.net+vb web there is a gridview in which i use a radiobuttion list as selectparameter. it works fine
there is a label in that page with code behind as under
Protected Sub RadioButtonList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadioButtonList1.SelectedIndexChanged Label1.Text = GridView1.Rows.Count.ToString() End Sub count gets displayed but
if i select the first one at that time it will be 0
when i select the second one that time it shows the count of first selection
when i select the third one at that time it shows the count of second selection
how to make a item the default from a dropdownlist, I want to make the value GBP as the option selected when the page loads, i've spent all day trying to get ddlist to work and now i'm stuck on this.
this
.ViewData["ddlCurrency"] = new SelectList(ws.ToList(), "dboCurrencyID", "dboCountry", new SelectListItem { Selected = true, Text = "United Kingdom (GBP)", Value = "GBP" });
Question basically crams it all in... I'm loading a page with a querystring (ID), and I need to use that ID to set the selected item of a ListView when the page loads. The ID is a DataKey on the ListView. I have no code of value to post--none of my attempts at this work.
In my project i Found the following error while submitting the form
"Input string was not in a correct format"
Here below my code
public partial class Add_product1 : System.Web.UI.Page { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DEMO_DbConnectionString"].ToString()); SqlCommand cmd = new SqlCommand(); SqlDataReader rdr = null;
I am using aspnet menu control and i want to hide the item initially on page load and show the item after an event is trigger say button lick event Can any one give me an example?
I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
In an ASP.NET 2.0 project I've got a RadioButtonList. I'd like to disable one of the items in this list, but when I change the Enable property of an item to false it just wrappers the item with a span instead of disabling the Input when rendered to Html:
I have a table cell with a RadioButtonList. When each item is selected, the SelectedIndexChanged event is supposed to fire so the app can populate a related listbox. The problem is it stopped working. Now if I selected the first entry 'Division', the event never fires. I put a break-point on the event handler and it gets called for the other entries but not for Division. I'd believe it if some other code is interfering, I just don't know where to start looking.
[update] By not working, I mean if you selected Item #2, the update works; then if you select Item #1 it doesn't. If I change where the 'Division' item appears in the list, it still has the problem. Is there something in the page load cycle that could be aborting the event handling chain?
Is there a way to set tab order on each ListItem within a RadioButtonList? The listitem does not have a TabIndex attribute, so can this somehow be done via javascript?
A similar thread indicates there is not a way to do this [URL], other than using individual RadioButtons instead of a RadioButtonList.
I have a RadioButtonList with some fixed element and a default selected. If I uncheck the selection with javascript, on postback the SelectedIndexChanged event is not fired.
I would expect that the SelectedIndexChanged is called because the index is changed to -1.
As far as I know, the stage of data collection from the submit of the form is handled by IPostBackDataHandler.LoadPostData method.
I derived a class from RadioButtonList to verify when LoadPostData is called and I noticed that when non of the radio button is selected the method is not called and the same for SelectedIndexChanged event.
it seems that if the key of RadioButtonList is not present in the Page.Request.Form.Keys array, the LoadPostData is not called.
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items) { if (item.Selected) { //lblResults.Text += item.Text + " "; Label1.Text = item.Text; } }
I am working with a model which has the following, basically a Project can have a score between -5 and 5 and I'd like to show a dropdownlist of the available options, i.e 5,4,3,2,1,0,-1,-2,-3,-4,-5.
[Required(ErrorMessage = "Score is required")] [Range(-5, 5, ErrorMessage = "Score must be between -5 and 5")] [DisplayName("Score")] public double Value { get { return value; } set { this.value = value; } }
What would be the best way to accomplish this using a dropdown list and how can I make the score of 0 the default selection?
I have a drop down list control populated with items and some code to take the currently selected item value. The problem is I only get the value of the first item in the list regardless of what item is actually selected. Here is my code to populate the drop down:
protected void displayCreateCategories() { StoreDataContext db = new StoreDataContext(); var a = from c in db.Categories orderby c.Name select new{catName= c.Name, catId=c.CategoryID}; ddlCategory.DataSource = a; ddlCategory.DataTextField = "catName"; ddlCategory.DataValueField = "catId"; ddlCategory.DataBind(); }
To get the value of the currently selected item which in my case is always of type integer I do label1.text=Convert.toInt32(ddlCategory.SelectedValue); I get the selected value, but it is always for the 1st item in the list. I'm pulling my hair out over this.
I am using a radiobuttonlist in my project. Where i want to hide one of radiobuttonlist item visible true or false. according to the selection of the country. I am able to hide the radiobutton but the corresponding text is still displayed. How to hide both radiobutton and also the related text.
