I'm using asp.net MVC 2.0, my controller coding is,
foreach(DataColumn dc in dtImport.Columns)

I have many controls on my form, but in particular, I have 2 dropdownlists. 1 dropdown list has 2 values, and each value controls what the second dropdownlist displays. This is an edititemtemplate and both dropdowns have the selecteditem set via '<%# Bind("fieldname") #>' on page load.
THe problem is, if I change the value of the first dropdown, it errors out because the second dropdwon has a bound value that is no longer acceptable.
Can I cancel the bind of the second control, if the the first one is changed? I would like to cancel the bind, and update the values by using a different datasource depending on the value of the first dropdown or hardcode the new values.
If Dropdown1 has a value of "A" for example Dropdown 2 Shows Values "1", "2", "3"
If Dropdown 1 has a value of "B" , Dropdown2 Shows Values "4", "5", "6".
It binds fine initially, but if I change Dropdown1 from A to B, I want Dropdown2 to show the new values, maybe with a default of "Select an Item" and not error out b/c it's attempts to bind a value of 1, 2, or 3.
Hope this makes sence, b/c I'm
I have many dropdownlists in my application, and have never had a problem binding the data to them and setting the selectedvalue. The ddl is in a DataGrid, and I look for the value in a label control and set the .SelectedValue to that. I actually copied my code from a different page in my application that functions exactly the same way, except on the "original" page the .SelectedValue changes as expected. On the "new" page I can see that the Value in the label control in the datagrid has the expected value, and as I step through the code everything is just fine until I hit the .SelectedValue = NewValue. I can see that the current .SelectedValue is populated with the default value from the databinding, and that the NewValue has the new value I want, but after I step over that statement, the .SelectValue remains what it was as the default value. So, here is the code:
Protected Sub dgWatchList_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs)
Dim ddlAuditor As System.Web.UI.WebControls.DropDownList
Dim AuditorID As Integer
If e.Item.DataSetIndex >= 0 Then
AuditorID = CType(e.Item.FindControl("lblAuditor"), Label).Text
ddlAuditor = e.Item.FindControl("ddlAuditor&
I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
Please let me know how to fix this. I tried UpdateMode conditional and always but didn't worked. If I am not clear let me know.
i wanted to retrieve things from the data base and perform mathmatical operations on it then post it to the user, so i was told to use the bullited list and bind it to the object dataSource
how to perform such thing??
Hey all, I've been working on a little application page that will give users the option to say whether a list should allow duplicate title entries.
I am able to pass the current list GUID to the application page using this:
within a custom action which I've added to the list settings. I'm kind of stuck now....
I'm not sure how to grab this GUID out of the url, and use it so I can bind the current list with my event receiver. Every example I've seen of binding has used a hard coded list name which is fine as an example, but isn't the best for real applications.
Or is there a way to use the GUID to get the lists name which I can then pass to the spweb.Lists[var] ? Since I won't know the list name beforehand.
Hope all of that makes sense, any suggestions are appreciated.
