I have aspx page.having an issue is that if we select first time option from drop down value gets appears on the page.but when we select second time option from drop down still previous data getting appears. how do i clear all the previous data after drop-down SelectedIndexChanged Event..?
As you have not provided the code when i'm writing this answer. In Asp.net u can achieve this by using jquery. I'm using club dropdown list with ID clubs as an example. This event will bind to the list and will keep on updating selected variable when the selectedIndex change. Then you can simply pass the selected variable value to lets say a span element with id spanClub
$(document).ready(() => {
$('#Clubs').change(() => {
let selected = $('#Clubs :selected').text();
$('#spanClub').text(selected);
});
});

I have a ListView and it adds an item per second dynamically in C# WPF. Since I feel it will get stuck after thousands of items I clear it when it holds more than 100 items.
But then it doesn't look good and disappears all of a sudden. Is there a way by code to make it look like items continuously flowing? How can I delete a particular item when it reaches to 100 items so the items would look like flowing?
Before adding new items check how many are already there and remove some (the oldest ones in the beginning) to stay under limit:
int limit = 100;
while(myListView.Items.Count >= limit)
{
myListView.Items.RemoveAt(0);
}
myListView.Items.Add("new item");

In my application I am trying to hide the values in my drop down list while it carries out the required functionality. As shown below you can see the drop down showing a value. The values are being pulled from a database.
When selected it would show the values below:
I would prefer if the values are not shown. Meaning I would want the dropdown values to not be shown but still carry out the fill operation as shown above.
So to explain more clearly, My comboBox which contains the value "123456789" would pass the values "P10434" and "Jev Pharma" to the respective textBoxes below respectively.Instead of showing my dropdown values while typing(auto suggest currently does this) I would instead want the dropdown list to not suggest any values at all. Meaning once I type "1234567..." it would not show any values int he comboBox but rather accept the info being typed in and pass the corresponding values from the database to the texboxes below.
I have tried changing the properties of the comboBox by removing append and suggest but the functionality is different. It no longer fills the data but instead just allows typing of a value. I am not sure how to approach this. Any suggestions?
Set the properties as follows:
comboBox1.AutoCompleteMode = AutoCompleteMode.Append;
comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
comboBox1.DropDownStyle = ComboBoxStyle.DropDown;
This will append the suggestions when typing without showing the list.
You can handle the appropriate event per your requirement to fill your textboxes.

I'm building a dynamic list of RadioButton inside a For loop
using
<%= Html.RadioButtonFor(m => m.Gender, m.Value) %>
The dynamic list gets created alright but the first RadioButton is NOT VISUALLY checked
What I mean by this is that the circle portion of the RadioButton is not filled with the black dot that tells you it's checked.
However, when I inspect the HTML in the browser's dev tools, the attribute checked="checked" is set!
I tried doing a JQUERY onload
$("#yada").attr("checked", "checked");
$("#yada").click();
and NOTHING works!!! The inspector still says the element checked: true but still the little circle does not get the black dot in it UNLESS I manually click it.
I've also tried setting the first radio button like
Html.RadioButtonFor(m=> m.Gender, m.Value, new { checked = "checked"})
Just to give an answer to this question for anyone who encounters a similar issue (without reading the comments):
If you manually set checked to multiple elements in the same radio button group (defined by the name attribute), only the last one will be displayed as checked, but once you click on one manually, it will reset all the checked elements to match your latest selection.
See this fiddle (https://jsfiddle.net/0ekaznbb/) for an example.
I think you tested code in Google Chrome. You should edit parent elements for solve this problem.

I am Creating an app with C#. I have a ListView on the Main Form(FormM) which lists all the record, i can select on record and edit it in the new form(FormC). Now I want to have a Navigator on the Main Form. Suppose that the FormC is open and showing a record for edit. in That case i want that if i click the navigate button on the Main Form, the value on the FormC changes according the next or previous move of navigation.
the Navigation buttons is in the FormC in any samples that i found in internet. but i want those be separated.
any sample or idea is appreciated.
In your FormM, make the listview a static member, to do this, go to FormM.Designer.cs, locate the declaration of listview and change it to public static type from private type. After you do this, plenty of errors will be reported in the same file. To fix those, replace all this.listview with only listview.
The above configuration will make your listview accessible from any other form. To access the listview from FormC, user FormM.listview.
Similarly change the Text box/area from FormC to public static. This will make the textbox accessible from FormM.
When you press next and previous buttons, change the selection controls between items and in the SelectedItemChanged action function, put the code to send the selected item to FormC's text box.
Eg: FormC.textbox1.text = {your code to fetch the selected item}
