I have a number of dropdown lists which are populated from a database. They load depending on what the previous dropdown selection was so for example if the system was car based and I had chosen Ford then the next dropdown list would populate all cars made only by Ford. What I'm wanting to do is add a select all to one of the dropdown lists. Does anyone know how this would be done?
View 1 RepliesI am trying to get the drop down list to only include table1 entries where table3.int1 is the current selection in another drop down list (table2.id). Example:
Table1: id, string1, int
Table2: id, string1, string2, dec
Table3: id, int1 (ref table2.id), int2 (ref table1.id)
Both drop down lists are inside of a FormView object for a asp.net page. My current select command(s) are having the DropDownList for Table1 display all Table3 entries, instead of just the ones Tied to Table2 id from the other DropDownList.
I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.
My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.
Now for the problem.
User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.
I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.
What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?
Here is my code

I'm trying to create a page with multiple fields to be used as parameters for filtering a GridView. I'm using a combination of two asp:dropdown lists and two check boxes. When I select a value in one ddl, I want to clear the value in the other ddl. I was trying to use the event "onTextChanged" but that doesn't seem to fire off on the client side and I cannot seem to find any event for an asp:ddl or asp:checkbox or asp:radio button that fires off on the client side.
Are there events, like onClientClick for asp:button, that fire on the client side for these controls when a selected value is changed or when the user clicks on them? or do I need to use html controls instead?
Example for Editable Grid with dropdownlist inside? Getting some problem in updating the data
View 3 RepliesI am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.
I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.
Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?
I have a gridview with following fields LECTURE ID,LECTURER NAME,SUBJECTS and gridview contains link Buttons to Insert,Edit and DELETE. what i need is, when i click, EDIT SUBJECTS columns should contain DROPDOWN Lists to select subjects. if the GridView row is not in the EDIT mode or INSERT mode DROPDOWN should not be displayed and display only the subject taught by the lecturer.
View 2 RepliesI have a date list in DropDown and there is no blank item in it. Dropdown item seems to be following:
01-02-2010
02-02-2010
03-02-2010
04-02-2010
DropDown is bounded by sqlDataSource.
If 04-02-2010 is the last date for today then I want to display 04-02-2010 by default in the dropdown if the page load.
We are updating data on daily basis. So on next day the date will be 05-02-2010 so when the data updated then 05-02-2010 should be shown iby default in the dropdown.
I have a gridview with two columns (item templates) one is a dropdown and the other is a textbox. I need to select an item from the dropdown (which I can do) and then get the cost of it and then put the cost in the texbox item template of the gridview. So I think I need to pass the row number and cost_id of the selected item to a procedure to get the cost of the item. Here is my so far code that I have now Idea how to pass the values of the gridview and then pass the cost of the item back to the proper row and textbox of the girdview.

I don't want to link my dropdownlists with a database like most of tutorials and forums show. I just want to link 2 dropdownlists, for instance if one says "Food" I want to show only the food producs in the other DropDownList. All this items are not from a database, I just inserted them in the DropDownList control.

How can i dynamically add textboxes and dropdown lists on a button click. I'll be showing 4 text boxes and 1 dropdown list initially with a link button ADD MORE, Then after clicking ADD MORE button i need to generate same 4 text boxes and dropdownlist exactly in the below row as in EXCEL sheet.
I'm having a SQL table with 4 textboxes and a drpdown list values as columns and i need to insert them into the database. i previously worked on the same requirement where i've collected multiple values frm a listbox control and looped all the selected items and comma seperated them and inserted them into table(here the case is different, there is only one row so it became simple and straight forward during insertion). Now i need to loop throguh all the 4 textbxes which user enters and need to insert those 4 textboxes values into DB under same columns.
I have an self-referencing entity which maintains a list of like entities that are it's children. What I need to do is build a dropdown that lists all possible parents so when I add or edit a new entity of that type, I can select it's parent (or no parent). The problem lies in the sql. I simply don't know how to word it.
IList<ParentForumModel> parentForums = new List<ParentForumsModel>();
foreach (Forum forum in forumRepository.GetAll())
{
// not sure how to handle this here because it isn't in the correct order. I need them to be grouped by parent and sorted by the sequence field. It also needs to be a flat dataset, not something uses IGroupedQueryable or some such.
}
ForumAddModel model = new ForumAddModel
{
ParentForums = parentForums,
// other properties
}
public IQueryable<Forum> GetAll()
{
return context.Forums.??? // what Linq do I need here?
}
If this simply isn't possible with Linq2Sql, then is there a system where it is possible? Please don't say hnibernate.
I have a dropdownlist and a gridview with a drop down list in every row. I have removed other cols in Grid for simplicity.
Whenever a new value in the dropdownlist is selected I would like to set all of the dropdownlists in the gridview to that same value via javascript. (Yea both the dropdownlist outside the gird and the ones inside the grid are populated by the same data source)
The dropdownlist:
<asp:DropDownList onchange="javascript:onJDSelection();" ID="DropDownList3" runat="server"
DataSourceID="SqlDataSource4" DataTextField="circt_cstdn_nm"
DataValueField="circt_cstdn_user_id">
</asp:DropDownList>
The GridView:
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" onrowdatabound="GridView2_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="Change to Job Designer" SortExpression="circt_Cstdn_nm">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("circt_Cstdn_nm") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:DropDownList ID="ddl_jd" runat="server" DataSourceID="SqlDataSource4" DataTextField="CIRCT_CSTDN_NM"
DataValueField="CIRCT_CSTDN_user_id"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
My current attempt:
function onJDSelection() {
var jd = document.getElementById('ctl00_MAIN_DropDownList3').Text;
var grid = document.getElementById('ctl00_MAIN_GridView2');
for (var i = 1; i < grid.rows.length; i++) {
grid.rows[i].cells[0].getElementsByTagName("*")[1].selectedText = jd;
}
}
[Code]...
When clicking on the dropdown I get an alert that says "test" and an alert that says "[Object object]" However nothing happens with the dropdowns in the grid and the alert(i) never fires.
I am trying to bind data into a dropdown list from c#. I am getting a Null error when trying to enter the data into the DDL's. I am using this code for the front end.
<asp:Repeater ID="RepeaterHardDrives" runat="server">
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%"> [code]...
and last but not least the function to setup the dynamic amount of DDL's looks like this
private void PreloadHardDriveRepeater(int intSupportedDrives)
{
int[] intArrDisks = new int[intSupportedDrives];[code]...
I am calling a list of populate functions in a !page.isPostBack if statement and the only one that is not getting the data is this one with the Drown Lists. It gets the number of Rows(18) from the database, but it it throwing a Null error(Object reference not set to an instance of an object.) I have seen quite a few people have been running into this error while googling the problem, however I could not find a solution that worked for me. The PreloadHardDriveRepeater function seems to work fine when run alone it loads the correct amount of DDL's onto the page.
I have a dropdown list which is bound to a gridview. I would like to add a dropdownlist item which, when selected, will default to displaying ALL gridview rows. So I would like as the first dropdown list item "All Items" and have this as the default.
