View 2 RepliesI'd like to setup some lunch-and-learn sessions in my company where we all watch a presentation of some programming-related topics. Where are some good places to find videos about Microsoft technologies with a clear picture and high audio quality that are about 30-60 minutes long?
They could be about design patterns, best practices, new language features, new frameworks, getting better performance, etc.
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.
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 a dropdown list in the edittemplate of a gridview and now it selects the first value that comes from the datasource. How can I get it to select it's original value? Where do I put the code?
View 9 RepliesI have a master page with an accordion in it inside the accordion panel1 are 3 dropdownlists (ajax cascading) and a button when the default page is loaded i want to select the dropdown values(this works) and then click the button to redirect to another page called test.sapx (this works). The thing i also want to do is pass the dropdownlist values to the new page as the dropdownlists reset. I was trying to do this through the click event on the button and set them in a session variable. The click event isn't firing at all. The page redirects and then if i click the button again it fires the event?

View 2 RepliesI 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 two dropdown lists and i would like if i select lets say "1" the second list returns "A""B" but instead it returns "A" how to make the second list display A"B when i select "1" from the first list.
View 12 RepliesI 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;
}
}

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 user requirement to hav the ability to directly edit the gridview without having to click the edit link. I was thinking of showing dropdown lists for each column-to-row so that the user can select the values for each record. Then the table will be updated accordingly (no update link).
Is this possible or do I still need the edit template and specify the item template with the dropdown list?
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.
View 9 RepliesI have 3 dropdown lists. All 3 are using the same generic list for there items. I am using C# as the code behind. The code below shows the DTO list i am using and how I'm adding them to the drop downs...

I have a simple web form which has 3 dropdown lists making date of birth dd mmm yyyy. The form itself is inside an update panel. The 3 lists are populated once on page load, list 1 has 31 days, list 2, 12 months and list 3, 82 years. The strange behaviour affects list 1 - (days) and list 3 (years). When I select an item from the list which is outside the viewing window via the scrollbar (20 is outside 19 is the last in the list) and press the validate button the whole page flickers. The same behavious occurs in list 3. It doesn't occur in list 2 because the viewing windown is large enough for all 12 months. If I then select an item within the window, the flickering stops.

I need to validate ajax cascading dropdown lists. See code below. It does not work. Could anyone help on it. I use VS 2008.

I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem).
What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected)
.
I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others).
All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where.
EDIT: Final solution looks as follows:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton>
<asp:Panel ID="pnlCompany" runat="server" style="display:none">
<div>
<asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList>
<br/>
<asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" />
<asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" />
</div>
</asp:Panel>
<cc1:ModalPopupExtender ID="mpeCompany" runat="server"
TargetControlID="lnkCompany" PopupControlID="pnlCompany"
BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo"
DropShadow="true" PopupDragHandleControlID="pnlCompany" />
</EditItemTemplate>
</asp:TemplateField>
And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView:
Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs)
Dim intRow As Integer
Dim intVal As Integer
RestoreFromSessionVariables()
Select Case e.CommandName
Case "SelectCO"
intRow = grdIDCostLabor.EditIndex
Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList)
intVal = ddlCo.SelectedValue
lstIDLabor(intRow).CompanyID = intVal
lstIDLabor(intRow).Company = Company.Read(intVal)
Case Else
'
End Select
MakeSessionVariables()
BindGrids()
End Sub

View 1 RepliesI 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
