Gridview Selectedindex Changed Not Firing On First Click?
Apr 1, 2011
Here is my code:
Protected Sub BookingsGV_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles BookingsGV.SelectedIndexChanged
BookingID = BookingsGV.SelectedValue
Dim query = From a In db.Approvers Where a.ApprovalStatus = False And a.BookingID = BookingID
Select a.ApproverEmail()
ApproverList.DataSource = query
ApproverList.DataBind()......
When I click on a row for the first time it is selected but nothing fires and my details panel is not displayed. When I click for the second time I get the expected results.
I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.
I am using a dropdownlist in my application and it has corresponding SelectedIndexChanged() event.I would like to invoke GridViewEdit Event when SelectedIndexChanged event fires from dropdown list.Is it possible to implement this...??
<asp:DropDownList ID="ddlStatus" Visible="true" AutoPostBack="true" OnSelectedIndexChanged="ddlStatus_SelectedIndexChanged" runat="server"> </asp:DropDownList> protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e) { //Code to fire the GridViewEdit Event to put a row in edit mode }
I'm trying to load a gridview based on selection from dropdownlist. When i run the program, it displays empty gridview. How to solve this?
Name of dropdownlist: CatCode
Code behind:
Private Sub BindProdGrid() Dim conString As String = ConfigurationManager.ConnectionStrings("SY_InventoryConnectionString").ConnectionString Dim rowIndex As Integer = 0 Dim box11 As DropDownList = CType(SalesGView.Rows(rowIndex).Cells(1).FindControl("CatCode"), DropDownList)
I wanted to create a dropdownlist that would trigger an asynchronous postback and update the Gridview inside the Updatepanel. However, no matter what I do, when the dropdownlist changes, nothing in the UpdatePanel will change, even the TestLabel....I've been banging my head against the walls for days on this -- why won't this work? When I remove the UpdatePanel code and triggers, all the code works, eg, you change the dropdownlist andthen gridview updates -- but it refreshes the page and this is why I wanted to put the Gridview inside an Updatepanel to make it look cleaner.[Code]....
i can populate cascading dropdownlist by using webservice now. but may i know how do i trigger function while selectedindex changed? (without using auto postback...)
I have an asp.net page with a list box on it. Multiple event handlers subscribe to its OnSelectedIndexChanged event.
When I change the SelectedIndex programmatically none of the events get fired.
Now a hack for this is to call each event handler, but this has already caused bugs since people didn't know they had to do this when adding a new event handler.
I can do this in a Winforms app and even when SelectedIndex is changed in code the events fire.
I am trying to use Yes No Confirmation Message Box but the code below here which i found here uses a button to raise the confirmation message box but what i would like to use is a DropDown. How can i modify the code and i use drop-down box instead of using a button? here is the javascript code:
<script type = "text/javascript"> function Confirm() { var confirm_value = document.createElement("INPUT"); confirm_value.type = "hidden"; confirm_value.name = "confirm_value";
[code]....
but here is what i would like to use is drop-down instead of the button:

Need to have the ability to change the view of my gridview based on button click, the easiest i can describe what im trying to do and need is if you have every been on any e-comm site where you get a list of items presented to you.. normally you may get a thumbnail, description and price.. but at the top of that list you get the option to view it as a list with no thumbnails and so on..
Is gridview the best control to be using if i want to do that? example of what im needing is similar to walmart.com
if you search for a product doesnt matter, when the results are presented to you, you have it in what they call "List View", but you have the option to view it in "Grid View", not sure if they are actually using listview and gridview controls.. but i want the same end results..
What would i use or what can i search on to accomplish the same thing.

I have a bunch of controls in a Content Page ( A registration page, right) to gather information concerning a user. One of controls is for the UserName. I want to check that the UserName is unique so I place code in the TextChanged event of the TextBox control for the UserName. I have abreak point set in the event procedure and it never gets hit! This is my first attempt at using Master/Content pages. I have looked in the MSDN Library for many hours concerning this problem without any success. I need to know how to check whether the UserName is currently in an Access database.
I am calculating discount at text changed event when user enters the discount%. To edit when i load the data from table using dataset i do not get the correct data as it is in the database. For ex if quantity is saved as 5000.00 in table and when i try to fetch it.. I am getting it as 500000. Instead of 5000.00. Is it because of text changed event? How do i resolve this?
I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.
On grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { TableCell cell = new TableCell(); ImageButton bttn = new ImageButton();
[Code]...
That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click); private void b_Click(object sender, EventArgs e) { //delete record }
I have a simple query based on the index changed event of a dropdownlist in ASP.NET. The scenario is i have a dropdown list bearing a collection of items (say ONE, TWO, THREE, FOUR, FIVE) with the default value selected as 'ONE'. Now, when the client changes the index (say the client selects 'TWO'), a confirmation box is prompted asking 'Are you sure want to change the index?' with the buttons YES & NO. Now, the problem is, if YES button is clicked then its working fine as the index is changed. But when NO button is clicked in the confirmation box, I do not want the index to be changed to 'TWO' and it should be holding the previously selected value which was 'ONE'. How can I do this? For which event should I write the code, as I cant think of writing the code for the IndexChanged event because here the index change has already occured and since there is no 'IndexChanging' event in ASP.NET, where shall i write the code
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.
<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've dynamically created new rows on button click in gridview with 3 dropdownlist.for the first default row the selectindexchanged is firing and on pageload 1st ddl is loading with values and basing on selection the second ddl is showing values and third ddl is showing basing on second ddl. Now, when i click add new row, a new row is created with 3 ddl's ...1st one is showing properly but when i select from that ddl ,it should show data accordingly but its not showing particular data but showing all realted data from DB.same for 3rd ddl.
Also when new row is added and the first ddl is selected on postback the second ddl data is refreshing..
I have an ASP.NET 3.5 web application. There is a Master page with lots of client script and some simple server side controls. I have a user control that has a modal popup extender inside an update panel and some client script as well. When I add this user control on the Master page inside a new update panel whose update mode is set to conditional, and I add a link button whose click will initiate a method of this user control, the Master page's behaviour changes in a strange manner. All the buttons and link buttons start to fire their Click even on the second click. Nothing happens on the first click. As soon as I remove this user control from the Master page, everything seems to get back to normal and Click event fires on first click as it should. I hope I have clearly mentioned the problem here. I have already spent quite a long time trying to find out the reason for this but of no use.
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
I have a jqGrid with four columns and in which i get the rows from the database. Now i want some thing like this. On row selection the cell value of row has to be changed.
i.e.
SNo SName Update Roll No 1 Steve Rename 1001 2 Jack Rename 1002
I want to update the SName when the user selects Rename from jqGrid row for example if the user selectes rename from first row then first row should be like the following
i.e.
SNo SName Update Roll No 1 Steve Update/Cancel 1001 2 Jack Rename 1002
