Forms Data Controls :: How To Place A Dropdown Control Iniside A Gridview Control

Jan 26, 2010

I have managed to place a dropdown control iniside a gridview control. The dropdown does indeed populate in each row... Question: How is it possible for the system to correctly select the text in the dropdown based on the value of the field which is driven from the database? Is it to do with the selectedvalue?

Forms Data Controls :: Trying To Incorporate The Use Of A Dropdown List Control With A Grid View Control?

Sep 24, 2010

I'm trying to setup a page that will utilize a dropdown list control inside of a grid view control using VS 2005 2.0 version. Everything that I can find online seems to only show the use of the dropdown list control using a data grid. I don't want to use a data grid because it doesn't have the functionality/ power as the grid view control. how I can incorporate a dropdown list control with the grid view control? Here is a copy of my code.

<asp:GridView ID="HardwareSetdv" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="AcctID"
<asp:CommandField ShowSelectButton="True" />
<asp:BoundField DataField="HardwareSetID" HeaderText="HardwareSetID"

Forms Data Controls :: Dropdown Control Within A Formview Control?

Jun 15, 2010

I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.

Forms Data Controls :: Using GridView With A User Control And Passing Object Into Control?

Jan 8, 2010

I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.

Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control

Forms Data Controls :: How To Control The Dropdown Which Is Inside FormView EditItemTemplate

Jan 27, 2010

How to write code in to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.

Forms Data Controls :: Dropdown List Control In A DetailsView Template?

Nov 10, 2010

I am using a DetailsView Control and have a "MemberStatus" field.

When using the templates in edit mode, I am using a dropdownlist to change the member status.


<asp:TemplateField HeaderText="Member status:" InsertVisible="False" SortExpression="MemberStatus">
<asp:DropDownList ID="ddlMemberStatus" runat="server" DataSourceID="adsMemberStatus" CssClass="eitField" DataTextField="MemberStatus"
DataValueField="MemberStatusID" Width="120px" SelectedValue='<%# Bind("MemberStatusID") %>'>
<asp:Label ID="Label6" runat="server" Text='<%# Bind("MemberStatus") %>'></asp:Label>

What I would like to achieve is, if the MemberStatus is changed during edit mode, e.g. from "Active" to "Deceased"

I would like to enable certain fields e.g. txtBoxDateDeceased, and attach a RequiredFieldValidator for the textbox field.

Forms Data Controls :: How To Re-bind A Dropdown List Control In A Formview

Oct 20, 2010

I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.

When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.

Forms Data Controls :: Grid View Control Paging With Dropdown

Dec 20, 2010

I am using grid view control with paging Like-:

void grdUpdateColumn_RowCreated(object
sender, GridViewRowEventArgs

if (e.Row.RowType ==
DropDownList ddl
= new
//adds variants of pager size
ddl.AutoPostBack = true;
//selects item due to the GridView current page size

li = ddl.Items.FindByText(grdUpdateColumn.PageSize.ToString());
if (li !=
ddl.SelectedIndex = ddl.Items.IndexOf(li);
ddl.SelectedIndexChanged +=
//adds dropdownlist in the additional cell to the pager table
Table pagerTable = e.Row.FindControl("pagerTable")as
//e.Row.Cells[0].Controls[0] as Table;
TableCell cell =
"padding-left"] =
void ddl_SelectedIndexChanged(object
sender, EventArgs
//changes page size
grdUpdateColumn.PageSize = int.Parse(((DropDownList)sender).SelectedValue);
= 1;
//binds data source
Grid view Like -:

It's working fine but problem is that if i select 10 and record from dropdown and record also has 10 then paging is not showing.

That's mean i select 10 from dropdown and record is 10 then dropdown also disable with numbers, suppose i need to select again 5 then i can't do this.
