Access :: Dropdownlist With A Concatenated Value To Gridview?
Nov 27, 2010
I have a page that I want to be able to amend certain user details.
The page starts with a drop down list where I query a table that holds the first and lastname of the users from an Access database. I concatenate the results so the full name appears in the drop down.
Then the problem comes when I click on a name I need it to populate a GridView with some of the details about that user with a Select and Delete button.
Because I'm using this as a query for the drop down and combining the two values the subsequent gridview query fails to take the value.

I have a dropdownlist in a headertemplate but I can't seem to access it in the code behind to work with the onselectedindexchanged event. I want to change the data that is shown on the event but can't access the control.

I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddl as DropDownList
FillStateList(ddl)
e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
DirectCast(Gridview1.Rows(e.RowIndex).FindControl("ddl"),DropDownList).SelectedValue
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?

Code:
sbJavaAlert.Append("alert( "" + msg + "" );");
I can't stand appending a concatenated string. Isn't that the purpose of using a stringbuilder? This is another developer's code and I am adding onto another part of it, but I want to change this too. Or should I just let still waters lie, as the saying goes?

I have two Drop Down Lists (DDL), DDL1 & DDL2 respectively. DDL1 gets populated with "State" from a backend database where as DD2 gets populated with TWO fields "LATA" & "LATA Name" concatenated together. Here are the codes for the DDL2 :
[Code]....
The code behind the Submit button is using Querystring and directing to the next page:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Redirect(String.Format("Option1_result.aspx?ddl2={0}& ddl3={1}", HttpUtility.UrlEncode(DropDownList2.SelectedValue),
HttpUtility.UrlEncode(DropDownList3.SelectedValue)))
End Sub
My problem is: How to retrieve data from a Querystring which contains data from two concatenated SQL columns? I want to selectively retrieve only the first three digits in the ddl2 Querystring which will give me the LATA number.

I should probably post this question to a different forum but I've had such good luck on this one, I hate to leave...I have an SQLDataSource which has a concatenated field of FirstName + ' " + LastName AS FullName. That datasource is used to populate a Primary Contact combobox in the GridView based on the dsOrganizations datasource. ComboBox datasource = dsContacts, TextField = FullName, ValueField = ContactID, ValueType = Int32
nfortunately, not all the Organizations have Primary Contacts listed yet so the above substitution breaks and doesn't even show the Primary Contacts when they existWhat I need is someway to either leave the Primary Contact row blank in the DataGrid or replace it with "[none selected]"

I have to display data (names) in a random order on the website. The data is stored in a MS Access database. The names must be displayed in a GridView and DataList in different places. I have created a query in MS Access "zorder: Rnd([MarinaAccommodation]![ID])" which works fine in MS Access giving me a different order each time.
The problem is that when I try run it on the website the order remains the same, it does not change each time the page is loaded.

I have my code output a gridview with all the data with an option to select records. I'm trying to make a code which would allow me to select a record, and then print this record using a specific Report stored in MS Access.
I've located the code to print the Report it self, but it prints ether all the records or a range.

I am trying to add a client side event to a dropdownlist and I need to access the currently selected Text. I have tried:
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text.Equals(' UNASSIGNED');");
and
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.text.Equals(' UNASSIGNED');");
Both of which give me runtime errors when the event is fired.Whats the correct way to access this text property client side?I tried this but it does not enable the checkbox...
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text == ' UNASSIGNED';");
ANSWER:
Well, along with having to use == rather than .Equals, when you set a checkbox.enabled = false on the server side it raps the checkbox in tags and sets it to disabled=true; therefore you must set BOTH the checkbox.disabled = false and checkbox.parentElement.disabled = false; on the client side to enable the checkbox!The solution:
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').parentElement.disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED'); document.getElementById('" + chk_techreview.ClientID + "').disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED');");
