View 7 RepliesWeb Forms :: Populate Textbox Using SQL Database Query / Depending On A Dropdown List Selection
Apr 8, 2010I would like to alter the query that is run, depending on the selection made by the user in a drop down list on the same page. Would this best be done using a partial page update (AJAX)? Ideally it would be great to have the textbox result change quickly once the drop-down list value has changed, without a full page postback. I would like to change the SQL query to a completely different query if the user selects an option different to the default (page_load value) in the drop-down list. I would then like the newly retrieved result to be displayed in the textbox as before.
My current VB function looks like this:

Forms Data Controls :: GridView Page Reset Based On DropDown List Selection?
Jan 3, 2011i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.
How do I reset the grid view page back to the first page of August 2010 sales?
I am fairly new to ASP. If I have missed an imp. detail in this post, let me know and I will get that info. out there.

Change Databound Dropdown List Programmatically
Aug 30, 2010I have a drop down list that is populated in the page load event from a database table. The drop down has a DataTextField set to a project name and the DataValueField set to the project id (interger). Later I change the dropdowlist selected item with this code in the selectedindexchanged event of a gridview
GridViewRow row = GridView1.SelectedRow;
ddlProjectList.SelectedItem.Text = row.Cells[2].Text;
Does Changing the drop down list with this code cause the DataValueField property to change to the correct Project ID number also? If not is there a better way to do this? actually this code seems to be adding an additional item to the list so that the project i set with this code is listed twice so I don't think my code is correct

View 3 RepliesWeb Forms :: Populating A Dropdown Box With Contents Based On The Selection Of Another Dropdown Box
Sep 16, 2010I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server
Page_load Fires Twice For UpdatePanel Refresh Whilst Having A JQuery Bound Change Event On A Dropdown List?
Sep 11, 2010I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
why the erroneous page_load event is firing ?

MVC - Change The Value Of The Text In The Textarea?
Jul 12, 2010I have a WYSIWYG editor set up using ASP.NET MVC. When I post, everything is fine, however when I post and there is an error when the page comes back and shows the errors, the value in the textbox is messed up (it has become un-HTML Encoded) and for form validation reasons, this is fine. My question is this - how, in the controller (preferably), can I change the value of the text in the textarea? Even if I use a ViewData["fieldname"] and set the asp code to:
<%= Html.TextArea("fieldname", ViewData["fieldname"], new { id = "fieldthing", name = "fieldthing", cols = "80", rows = "10" })%>
It still doesn't work because that ViewData is the default value which, after the post, isn't returned to that value, it stays whatever was typed.
So any thoughts on how to edit this value? I tried passing in a new view, but that didn't work either.

View 6 RepliesMVC :: Html.TextArea - Extra Line Break In The TextArea, Just Above The Original Text?
Jul 15, 2010I'm working with an MVC1.0 web app and I've found a bit of an odd anomaly.
I have a search box on the first page (normal text box) and the input from this is passed through to the ViewData and on to the second page.
On the second page, I render a TextArea with this search input text from the ViewData.
Eg:
[Code]....
The problem is, there is an extra line break in the TextArea, just above the original text.
Stranger still is that if I now submit this page and the view is reloaded (after validation fails) - the original string of text has been trimmed and has no line breaks, but the TextArea now has 2 line breaks above the original text.
This can be repeated - every time the page reloads it has another line break.
It's driving me insane - does anyone have an idea on how to fix this?
FYI, you can check it out yourself - on your mobile phone, browse to [URL], punch something in the search box and hit search. You'll notice one line break added the first time the page loads. Then just hit "Find Best Offer" without entering a budget or selecting a category, and you'll see what I mean about the additional line breaks.
