I am using GeoMap in my website, and GeoMap is little below in Web Page.I am using filters in GeoMap, i.e., when user selects any station and clicks on "button", all the locations related to selection shows in GeoMap. But everytime when I filter and click on button, page loads and scroll upward then again to see the filteration result in Geo Map, I had to scroll down my page.I want that when I filter any station and click on button, page should stick to that GeoMap section. It should not go upward until user scrolls the page.For this I tried using "Update panel" but then GeoMap javascript is not working.
View 1 RepliesI want to stop postback if a certain value from a ddl is selected.
I've used VB to create a page whereby if a certain value from a ddl is selected then a hidden panel becomes visible. The problem is the likely answer to a majority of my ddl's is 'No' (or a no type response), however, even though the panel visibility remains false upon selecting No a postback still occurrs, the page refreshes and moves back to the top. I suppose this is a question with 2 possible solutions (or 2 questions rather)
1: Is there anyway of setting postback to false if selected value = No? A typical example of how my code appears is below
[Code]....
(i've used the value '1' to represenet Yes)
2: Is there a way of setting the page position after postback? As you can see in my code above i've set the focus on the next control (being a Radio Button) but i mean, is there an actual way of defining where the scroll bar is set?
I have a Gridview inside and UpdatePanel, Rows in this Gridview contains a DropDownsLists, each row has this attribute:

If i click on the dropDownlist Contained by the row, this algo launch a postback, so I can never see this DropDownList deployed.I need a Way to stop this postback. Is teher a solution for this?

firstly i am not really an ASP.Net developer but i do work in C#.
Anyway one of the application that i develop has an ASP.Net section and i need to amend it.
I want to add a Checkbox which when Checked by the User will set a Session variable.
This Session variable will then be accessed on another page where it will include/disclude some SQL and therefore change the behaviour of a Search.
So i have 2 Pages - Page1 that has the Checkbox on it -

I have a JQuery Dialog that is opened when a button is clicked. The first time around, it should do a postback, but when the dialog closes and I click the refresh button of the broswer, it sends the data again and duplicates the data I just entered. Should I add a return false somewhere so it doesn't postback when the dialog is closed. Here is the script:

When I use a RadEditor I want to enable the editor's spell check (working thus far). After a spell check the user can either click on the radmodule (toolbar thing) to either "finish spellcheck" or "cancel." Which is all fine and dandy except the "finish" button causes a postback!! I don't want that at this point!! "cancel" more or less does what I want to happen - I mostly just want a "done" or a way to stop the postback.
I've tried an Update panel but that just grays out the text area after it does the update.
On my form I have a button that pops up a panel to select an option from. It does a postback to fill in a textbox with the selected data. The other controls such as other textboxes and dropdowns are reset. Any way to stop this? Or do I have to save the settings and set it back on the postback?
View 4 RepliesI have a textbox with an autocomplete extender.The user types in a few chars and usually gets a few to a few hundred suggestions back.And its pretty quick.This is on a formview control at the bottom by the paging. It is for a "Go to" feature.But it is returning the suggestions from the same list of search results from the previous page.(It's really the same page but I just toggle the visibility between the GridView Results and the FormView details).And if they select "All Tickets" its possible to get 5000 results from the search.
Now the autocomplete is really doing the same search as the search results did which is like 46 seconds. And then weeding it down further with the prefix (chars they type in the autocomplete textbox).I have a Return to list button. And I want the Button to interrupt, stop, cancel, abort, or somehow just not wait for the WebMethod to finish, and do a PostBack right away.Since btnReturnToList is a normal postback I can't really use PageRequestManager to check if in async or last postbackelementId or anything.

I've set Culture="auto" UICulture="auto" in @Page directive and EnableScriptGlobalization="true" EnableScriptLocalization="true" in script manager to have client culture specific date format in my textbox.
I also have a Go button on my page on which I will do a partial post back. So, I want to validate the FromDateTextBox in javascript when the Go button is clicked.
UPDATE
I know how to create a javascript click handler. But because masked editor is already validating the date on focus shift, I'm thinking there should be some boolean property (like IsValid) exposed by it which will allow me to see if the text box contains valid date.
FURTHER TRIALS
I also tried below code and Page_Validators[f].isvalid always returns true even when the date is invalid and MaskEditValidator shows me a red star near the Text box.
function isDateValid() {
var b = true;
for (var f = 0; f < Page_Validators.length; f++) {
if (!Page_Validators[f].isvalid)
b = false;
}
return b;
}
$('#GoButton').click(function() {
if (!isDateValid()) {
return false;
}
loadProducts();
});
way to stop browser history population in a textbox?
View 4 RepliesI want to stop user from entering stuff in a textbox. But if I use Readonly then for some reason I can't get the information to the database.
View 4 RepliesI have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" onchange="calculate()" runat="server" Text="0"></asp:TextBox>

View 1 RepliesI am having trouble formatting the date on a textbox I get the error above if I don't enter the date in MM/DD/YY format in the textbox. I am also using this in a FormView so I can't format it or don't know how to in the code behind so if there is a way to format it in design view that would be preferable. Does anyone have any ideas on how I would do any of this.
