Setting A Drowdown List To The Value Of An Existing Record?
Mar 24, 2010
I have three dropdown lists which perform as cascading lists. #1 sets the filter for #2 and then #2 does the same for #3 (standard stuff). Each dropdown gets its data from queries to separate tables.
My problem is when I pull data from an existing record and assign the data fields to the controls using the datareader the second list will not allow me to assign a value to it.
The dropDownAssetGroup.SelectedValue sets easily to assetGroupID but the dropDownAssetType.SelectedValue won't take the value of it assetTypeID (which does get the correct value), it stays as "". The values in the existing records are contained in the dropdown's items, and were even populated from the same controls.

I can't for the life of me remember how to do this and I'm sure someone will answer this pretty quickly. I need to insert or update a record based on if it exists so in the SP I need to do:
SELECT * FROM table1 WHERE LinkedID = @ID Then I need to check if any rows were returned and apply it to an if statement which is where my mind is blocked.

I need a way of doing the following:
I receive data in .csv format. I have a some records on a table, so what I need to do is to check if the data I receive exist on the table of records that I need to match against.
If the record exist, then an email/sms should be sent to notify me that the records has been matched and then that record should be flaged that it has been tested so that I don't test it again as the incoming data are saved.

I'm trying to set the ImageUrl property after I've uploaded an image so that I can display the newly uploaded image, but for some reason it's not working.
If I navigate from the record I've just updated and then return back to that same record, the image then displays. It just doesn't display right after I've updated it. Basically what I'm doing is this:
Sub FormView1_OnItemUpdated(Sender As Object, e As FormViewUpdatedEventArgs)
Dim MyImage As Image
MyImage = FormView1.FindControl("Image1")
MyImage.ImageUrl = "image1.jpg"[code]....
I've left out the path intentionally because I'm pretty certain that the path I'm giving is correct... again, if I navigate away from the record and then return to it, the image displays. In addition, when I view the "Page Source" to view the resulting html, the src property of the image tag is blank . So, it's not a path issue... the issue is that its not setting the src at all which is why the image is not displaying.

I would like to locate the new record in a paged list after the record is inserted to the database. Say there are 10 pages of records. Each page is size of 20 records and sorted by last namez of people. I add a new record with last name Murray. Using MVC, how do I position to the page where Murray is after a post back? The controller's New action return to Index view, but it always return to the first page.
1. How do I make the Index method or some other method to go to page where newly inserted record is.?
2. How do I make the browser scroll to the row where the newly inserted record is in a NON-paged list?

I have a dropdown list with a piece of code that is run when the value is changed:
<select name="SList" onchange="javascript:setTimeout('__doPostBack('SList','')', 0)" id="SList">
Everything works fine when manually done. As an option is selected, the onchange code is called.
The problem begins when I try to change the selected value using a piece of Javscript. I want to be able to automatically change the selected option using JS, whilst still having the onchange code called, exactly as if done manually.
I try calling this:
form.SList.value = "33";
The right option is selected, but the onchange code does not get called. So then I try doing this:
form.SList.value = "33";
javascript:setTimeout('__doPostBack('SList','')', 0);
The right value is not selected and nothing happens.
FYI, the code is done in ASP.NET and Javascript.
What can I run to change the selected option whilst still calling the onchange code?

I have a List<string> that I want to use as a datasource for the gridview, making the column a HyperlinkField type and passing the value clicked in the column in the url. My code:
private void DoBind(GridView grid, List<string> Accounts)
{
Hyperlinkfield field = new HyperlinkField();
field.DataNavigateUrlFields = Accounts.ToArray();
field.DataNavigateUrlFormatString = _urlToRedirectFromGrid;
field.DataSource = Accounts;
grid.Columns.Add(field);
grid.AutoGenerateColumns = false;
grid.DataBind();
}
I can't get this to work. The page throws an AJAX null exception when this method is called.

I am developing page for maintaing employee record using Visual Studio 2008, MS SQL server 2005. I am able to fetch and display all the employee information in gridview, the gridview have the dropdown list to display the employee type [ Part Time, Full Time, Permanent , Contract ], in the item template i am having dropdown list. IN the dropdown list i am displaying this. But While saving the record in gridview the droppdown selected index are changed to 0 of other dropdown list.
the user may be change the dropdown value from permanent to contract, or so. but while click on the save button in gridview, all the previous selection are gone, and always showing the first record of dropdown list. I know this is happening because we are doing dropdown list bind on onRowDataBound.
