Forms Data Controls :: Dynamic Gridview With Dropdownlist / Dynamically Set The List Values Based On Parameters (of The Row They Are On)

May 28, 2010

I'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).

The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...

I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.

I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId

I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:

Forms Data Controls :: Gridview Sort Expression - How To Reset A Gridview Or Prevent It From Doing A Sort

Sep 23, 2010

Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.

I have 1 Gridview that displays 10 different scenarios based on what button is clicked.

I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.

I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.

I tried this:

Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();

Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;

I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:

[Code]....

Here is an example of just one of those SLQ statements inside GetSQLQuery:

Forms Data Controls :: C# Dynamic Gridview Using Template Field As Control?

Mar 31, 2010

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.

After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

AJAX :: Dynamic Data - DropDownList Field Template With Cascading DropDown Extension?

Sep 10, 2010

Have spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension.Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated. The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values.Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :)Attribute I created:

C# - Sort Gridview With Dynamic Linq?

Feb 2, 2011

I have a gridview with several columns, 3 of which I'd like to sort. The source for the data is held in the session.

protected void MyGridHistorySort(object sender, GridViewSortEventArgs e)
{
var TheColumn = (e.SortExpression).ToString();
TheDataHistory = (List<ViewDataHistoryModel>)Session["SessionDataHistory"];
var test = "data.DataDate";
var NewDataSource = from data in TheDataHistory
orderby test
select data;
MyGridHistory.DataSource = NewDataSource;
MyGridHistory.DataBind();

DataDate is a valid column in the list but the orderby statement doesn't work. Ideally, I'd like it to sort with the variable TheColumn by writing something like test = "data."+TheColum; and then add a sort direction based on a boolean. I looked at the OrderBy extension method NewDataSource.OrderBy(test); but that doesn't work either.

Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?

Apr 1, 2011

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .

I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList

<asp:DropDownList ID="DropDownList_HP" runat="server"

AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...

This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help

http://msdn.microsoft.com/en-us/library/ms366709.aspx

So I changed the ListItem in the DropDownList markup to the following:

<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"

AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...

This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.

In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.

Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

Forms Data Controls :: Dropdownlist Won't Display Values In Gridview With Use Of Parameter

Jan 31, 2010

My database has 4 colums;

TraditionalID-------------TraditionalName------------Singles-----------Suppers

Singles and suppers are money fields for the price of same item. A bit like the price of a Small, Medium or Large item. What I would like to do is display the 'Singles' price and 'Suppers' price in seperate listitems so the user can choose 1 of them.

GridView:
Traditional Name__________Size
Chicken-------------------[DROPDOWNLIST]

DropDownList:
Price of Single is: 1.50
Price of Supper is: 2.50

My page loads up with the correct items in TraditionalName colum but the DropDownList is completely empty. I'm aware I don't have anything in for DataValueField and DataTextField but I have tried putting things in these attributes, like Suppers and Singles, but nothing works, so I have taken them out below.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="TraditionalID" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="TraditionalID" HeaderText="TraditionalID" InsertVisible="False" ReadOnly="True" SortExpression="TraditionalID" Visible="False" />
<asp:BoundField DataField="TraditionalName" HeaderText="Meal" SortExpression="TraditionalName" />
<asp:templateField HeaderText="Size">
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource2">
</asp:DropDownList>
<asp:HiddenField ID="RowTraditionalName" runat="server" Visible="false" Value='<%# Eval("TraditionalName") %>' />
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:The CodfatherConnectionString %>"
SelectCommand="SELECT Suppers AS Suppers, Singles AS Singles FROM [Traditional] WHERE TraditionalName = @TraditionalName">
<SelectParameters>
ControlParameter Name="TraditionalName" Type="String" ControlID="RowTraditionalName" PropertyName="Value" />
</SelectParameters>
</asp:SqlDataSource>
</ItemTemplate>
</asp:templateField>
</Columns>
