Web Forms :: Display Server Side Yes No Confirmation Box On DropDownList SelectedIndex Changed
Apr 29, 2014
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:
On a check box check changed I want to test some conditions and based on that I want to display a confirmation message. Based on the user action, OK or Cancel I want to proceed or stop the process. How can I do that. I tried this,
[Code]....
Even I click Cancel the rest of the code also executed. How can I handle this?
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'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 have an accordion control and it is working fine. Except that when i set selectedindex to -1 (server side) and the control colapses to have no panes expanded. The client side diplay style for the previously expanded pane remains in the expanded colour scheme even though the pane has collapsed.
I want to show the confirmation box in asp.net from server side:I want to call it from server side because I have to take the customer message from server side. I am using the below code
string str = "Are you sure, you want to Approve this Record?"; ClientScript.RegisterStartupScript(typeof(Page), "Popup", "return confirm('" + str + "');",true); // More code ....
Now it is showing the popup and irrespective of what I click, whether "ok" or "Cancel", my code is executing. let me know how can I restrict code to be executed when user select "cancel" in the confirmation box.
URL...In the above page, the button fires the javascript first, then the code-behind sub runs. The problem I have is I am in the middle of a code-behind sub routine that checks if a user is logged on the a PC. If there is a users logged on, I want the confirm popup to ask whether to reboot anyway or cancel. The code needs to dictate whether to call the javascript, not some direct button click. Then I need the remainder of the code-behind sub to execute based on the users choice.
I can call the client script in the code-behind sub using 'RegisterStartupScript...'; then I can get the page's form value. The problem is that the sub runs to completion without waiting for the javascript code to run. This causes code-behind variable to get checked before it's set by the client and it nevers works.
I have JQuery confirmation dialog function that called by server side code (C#)how to get its return value of that function? in this case the return value would be either Yes or No.I called it in button clicked event as below:
Code: protected void btn1_Click(object sender, EventArgs e) { string message = "Message from server side, please select yes or no"; ClientScript.RegisterStartupScript(this.GetType(), "Popup", "ShowConfirmation('" + message + "');", true); }
my question is how to get JQuery return value, in this case the return value would be Yes or No?
I am throwing a alert box using scriptmanager like this based on some condition.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('Would you like to be put on the wait list?')", true);
But it has only "ok" button. Is there a way to display a message box which has yes/no buttons so that I want to check some more conditions in the code behind.
something like this.
DialogResult result = MessageBox.Show("Do you wanna do something?", "Warning", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning); if(result == DialogResult.Yes) { //code for Yes } else if(result == DialogResult.No) { //code for No } else if (result == DialogResult.Cancel) { //code for Cancel }
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 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've searched high and low for a efficient and reusable way to detect, on a postback/server-side, if any input controls on a form have been changed and I haven't found anything other than client-side solutions such as DirtyUpdatePanelExtender. I've come to the conclusion that it must be either really simple or really complicated.Ultimately what I want to do is to perform a database update, or not, depending on whether or not the user has changed any input controls on the form. The only thing I've come up with so far is to save the original values as Viewstate variables and then compare them with the Request values on a postback, but that seems far from ideal.
I am showing a few textbox controls on a page and I have a Save and Cancel button. If the user makes a change to any of the textboxes and clicks cancel, then I want to prompt the confirm box if they want to cancel with data being changed. I can determine if data has changed by comparing session variables of the data to the actual values. And I know how to show a confirmation box using javascript. But it seems like I need to call this from the vb code rather that right there on the client?
I have a dropdownlist, who's items I bind from the codebehind file of an asp.net web page. After databinding, I want to set the selected index as the last item in the list, thus:
[Code]....
However, this does not work. When the page is done loading, the selected index is still zero.
I've a textbox in grid view control. When user inserts some value in textbox a confimation message should be displayed to user. eg. "Do you want to update record?". if user clicks on yes/ok then some code should be executed else if user clicks cancel/no the return to same page. I've tried using
ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "key2", "confirm('Do you want to update?');", true); on text changed event of textbox. But was not able to achieve desired result.
