Web Forms :: In A Selection Changed Event- How To Identify User Selection
Apr 7, 2010
I was wondering if anyone can help me work out what the user has selected in this selection changed event?his is what I have so far:
protected void rblNavigation_SelectedIndexChanged(object sender, EventArgs e)
{
string url = (GetCurrentPageName()).ToString() + "?" + Request.ServerVariables["QUERY_STRING"];
[code]...
The problem is that rblNavigation.SelectedValue is not the value that the user has selected to trigger this event. How do I get the value the user has just selected?I'm using C# and this selection event is inside my MasterPage.

Note: The answer marked as the answer, answers the questions in the Title. However, my underlying problem, using type ahead dropdowns, is solved by moving to IE8.
I have a drop down list that when I CLICK a NEW selection I want to cause a postback ("this.form.submit()") But only if the click on the dropdown list just changed the selection.
Note that OnChange will NOT work because when the selection is changed by the keyboard I would not want to postback because it is a type ahead dropdown list.
I also suppose I could use OnChange and check if the change was caused by the mouse.
Maybe if we can come up with both solutions and i'll see which works better?
EDIT: More information:
AutoPostback = true; will not work. (don't want it to post back when the selection is changed by the keyboard)
onBlur = doPostBack; I tried this, but the result is not optimal. The user has to click off the ddl after making a selection with the mouse.
Another way to state what I want to do, i think, is do a postback when both the OnChange and OnClick events fire at the same time.

With asp.NET control dropdownlist, there is a property AutoPostBack, if it is set "True", the whole page will be posted back.
If the aspx page include a html element "select" like:
<select id="list" name="list" runat="server"
DataTextField="Name" DataValueField="ID" ></select>
and it data is filled by code-behind.
Question is: how to allow this Select have AutoPostBack function too?

User selects a date from the date-picker and the date is put into a text-box.
But when i choose a date some date should check another text box date and give me the difference. The selection-change event does not fire (as expected).
protected void dtpleavestartdate_SelectionChanged(object sender, EventArgs e)
{
string a = "NO CHANGE";
a = a + dtpenddate.SelectedDate.Subtract(dtpleavestartdate.SelectedDate).ToString();
Response.Write("<script>alert('" + a +"')</script>");
}

I have form in ASP.Net 4 (C# backend) that a user fills out to enter a new game quote into my DB. I have created the form and this lets the user add only a single quote at a time, what I would like to do is give the user a drop down box to let him/her choose to add up to 5 quotes at a time. The problem comes in how to generate the extra input forms based on what the user chooses. I have been going over my ASP.Net 4 book but it really does not cover this.

I have EntityDataSource for DetailsView which is in Edit mode by default (showin Update, Cancel link buttons).
This datasource also has foreign key called PecID. If I change the value in textbox bound to PecID, it works fine.
Entering IDs is not very user friendly, so I add dropdownlist and new datasource.
When I select new value from dropDownList and press update the DropDownList's selection is restored to original (previous) value.
Other values in textboxes are saved as expected.
After few hours of trying to figure out what is going on, I got lucky. I figure out that it is important the order of TextBox and DropDownList in field template.
This is the working order (textbox before DropDownList)
[Code]....
This one doesn't work [Code]....

I am currently trying to implement a small class attendance system, where the student names are taken from a database, stored in a List<Student>, and bound to a Repeater control. Each row of the Repeater contains two columns: The first is the student's name, and the remaining column contains a RadioButtonList with three ListItems (Present, Absent, Sick).Now, once the user presses "Submit", I want to be able to store their attendance status based on the user selection. However, after submission, the SelectedIndex is always 0, no matter what option is selected.

I have a page with a Search button, a gridview and a listview. When the Search button is clicked, the gridview fills up with a resultset and has a 'detail' linkbutton on each row. When the user clicks on the detail link, the listview below the gridview fills up with details related to the selected gridview row. My customers have asked if when they click on the gridview row, it becomes highlighted, and remains highlighted while they are working on the detail in the listview. So, I need to highlight the row when clicked, remove the highlight when a new row is clicked (as well as highlight the new row), and remove highlighting when the Search button is clicked. The highlight needs to remain over postback since there could be a full-page postback.
I'm thinking JQuery is the way to go but I am a JQuery novice and so would need a code sample.

I'm new to ASP.NET. I 'm trying to figure out how to make an HTML/ASP page where a user puts in data, either in text fields or selection boxes, and on clicking a submit button all of there selected data gets dropped either into a Access 97 Db or an excel spread sheet. Are there any examples out there of this? Is there a place that has already created this and I can just look and the code and figure it out for myself?

I have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.
Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.
I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.
My questions are these...
Is there a better way to handle this quantity of records than a stored proc and combobox? A
ny examples of a method to populate a certain number of records then filter based on user action?

I have Gridview which allows user to edit record.I already build the event to save the new record, time and user machine information to a log database.However, this means a whole record is saved to the log... if the user just change one or two column/field out of say 20 fields, then there is a lot of waste. Also the change is not obvious.How can I log exactly which field(s) was changed in the record ?
