Manually Insert Items Into DDL After Data Binding?
Jan 4, 2010
I have a dropdownlist, which dynamically populate data from SQL Server and i wanna manually insert two items on top of the DDL after data binding. So, the DDL would has data something like this:
Select Branch (manually insert)
ALL (manually insert)
AIR
AMP
ABG
...
I tried to achieve it by using code below:
ddlBranch.Items.Insert(0, "Select Branch")
ddlBranch.Items(0).Value = CMM.sExcVal1
ddlBranch.Items.Insert(1, "ALL")
ddlBranch.Items(1).Value = "ALL"
but it comes out giving me the data like this:
Select Branch (manually insert)
ALL (manually insert)
('AIR' branch should be here but it's gone)
AMP
ABG
...
After manually insert the 'ALL' item into the DDL, the 'AIR' is gone which is already replaced by the 'ALL'. How can i remain all the data from server and at the same time i can manually insert two items?

I have a gridview that I am manually binding in my code behind page because I have to pull out information from other sources for the WHERE clause.The issue is that I get an error on the aspx page that one of the columns is not in the dataview, however when I run the SQL statement in SQL all the columns are there and there is not a spelling error.If I remove the column from the gridview then the page loads.I cannot see why the column is a problem.Here is my ASPX gridview code.
[Code...]
This is the line where the error occurs. <asp:Label ID="Label2" runat="server" Text='<%# Bind("date_submitted") %>'></asp:Label> Here is the code behind
[Code...]
Here is the ending SQL statement that works in SQL and does return the date_submitted column. SELECT id, title, date_submitted, (SELECT username FROM users WHERE (id = t.submitted_by_user_id)) AS submitted_by, (SELECT name FROM departments WHERE (id = t.department_id)) AS department FROM tickets AS t WHERE (closed_by_user_id IS NULL) AND (department_id = 48 OR t.department_id = 83) ORDER BY t.date_submitted DESC

Can you add a row of data programatically and bind it to the gridview? If so, how?
I have a grid with 2 columns. One of these columns is a template that runs a function and delivers an output. Within that function I need to manually add data that is not present in the sqldatasource to the grid and use it when performing aggregate functions.
ColumnA - ColumnB
1 - MyFunction(1) - adds new row (1, B)and returns A to column B.
2 - MyFunction(2) - May return just A
Grid should look like
1 - A
1 - B
2 - A
Even though SQLDataSource only returns
1 - AB
2 - A

I've added a simple SqlDataSource to my site with insert properties. I've also created some code behind to capture the insert command (oninserting="SqlDataSource_NewsLetterSubscription_Inserting").
Thing is how do I actually trigger the command to 'insert' from a standard button?
<asp:SqlDataSource ID="SqlDataSource_NewsLetterSubscription" runat="server"

I have two ListBoxes. I can move items from one list box to the other. I have an Insertcommand for inserting added values from the "ActivePrograms" list box to a db.
my problem is that it inserts only one item when sometimes the user added multiple items.
how do I insert all existing items from "ActivePrograms" list box?:
second issue: how do I make sure the insert command go through the list of items in the listbox and makes sure these rows does mot already exsited in the db? in other words insert only NEW values for that 'Id' value

I have a DDL bound to a sqlDataSource, and I want to insert an item in the first position. I tried using this code in the onDatabound event:
Protected Sub ddl_onDataBound(ByVal sender As Object, ByVal e As EventArgs) Handles ddl.DataBound
ddl.Items.Insert(0, "None")
End Sub
But when I load the page, the item "None" is inserted twice at the beginning of the DDL? So I see something like:
None
None
item1
item2
Do I need to put the items.insert somewhere else, like on the pageLoad, to avoid it being executed twice, or am I doing something really wrong?

I'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?

I can bind to properties in the ViewModel fairly simply like so:
<%=Html.RadioButtonFor(m => m.isCool, true%>cool<br/>
<%=Html.RadioButtonFor(m => m.isCool, false)%>not cool<br/>
but what if I wanted to bind to collection items within the ViewModel. I'm not sure if it's possible. Here's what I have:
My ViewModel:

I'm getting the following error: Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions.

I have a Gridview that displays paged results from a search query. The problem I am having is that the gridview is not displaying all the results returned from the query. For example, I can step through the code and see 6 items returned by the call to GetList(), but only 2 rows get rendered by the gridview after binding.
I am using an ObjectDataSource created in code:
ObjectDataSource ods = new ObjectDataSource();
ods.EnablePaging = true;
ods.TypeName = "Bll.InvestmentProductSvc";
ods.DataObjectTypeName = "Bll.InvestmentProduct";
ods.SelectMethod = "GetList";
ods.SelectCountMethod = "GetListCount";
ods.StartRowIndexParameterName = "PageIndex";
ods.MaximumRowsParameterName = "PageSize";
ods.EnableViewState = false;
ods.SelectParameters.Add (new Parameter("SearchString",TypeCode.String, SearchString));
ods.SelectParameters.Add(new Parameter("PageIndex", TypeCode.Int32));
ods.SelectParameters.Add(new Parameter("PageSize", TypeCode.Int32, gvSearchResults.PageSize.ToString()));
gvSearchResults.DataSource = ods;
gvSearchResults.DataBind();
The Gridview declaration:
<asp:GridView ID="gvSearchResults" runat="server" AutoGenerateColumns="False" AllowPaging="true" PageIndex="0" PageSize="50" OnPageIndexChanging="gvSearchResults_PageIndexChanging" PagerSettings-Position="TopAndBottom">
</asp:GridView>
Are there any reasons for the Gridview not to render a row and not to report an error? I have examined the data returned for the 6 items and cannot find any distinctive differences between the 2 rows displayed and the 4 rows not displayed.

I have a list view with a label that shows "Step #x", another label with the instructions, and then 2 linkbuttons for editing or deleting. At the footer of the ListView is another button "Add New Step" which opens up an empty TextBox and two buttons to save and cancel. I would also like it to increment the label, but I can seem to find the control in the code behind to change it's text. How do I do this?
Here's the asp markup:
<asp:ListView ID="lvSteps" runat="server" DataSourceID="ldsProcessStep" DataKeyNames="ID" InsertItemPosition="None">
<LayoutTemplate>
<div><asp:PlaceHolder ID="itemPlaceholder" runat="server" /></div>

I'm trying to populate 1000 ListItems in a ListBox.
how to do it. Currently only 100 items are being displayed even though I set the capacity of the ListBox to 1000.
Below is sort of how my code looks like. :)
listBox.Items.Capacity = 1000;
foreach(entity ent in enitityCollection)
{
ListItem listItem = new ListItem();
listItem.Value = ent.Id.ToString();
listItem.Text = ent.Name;
listBox.Items.Add(listItem);
}
entityCollection has 989 records in it.
Code does not generate any error. only that at the end of the loop I only get 100 items mapped to my ListBox.
Is this how the ListBox is designed for?

conn.Open();
for (int i = 0; i < ListBox1.Items.Count; i++)
{
li.Text = ListBox1.Items[i].Text;
}

What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
