I have a gridview which I databind to EntityModel
This typically looks like
something a
something b
companyID
on Login I get and set the compnay which has the ID so what in essence I want to do is on databind set the Where clause of data source to what the server side paramter for company ID is.
protected void BtnSave_Click(object sender, EventArgs e) {
try {
lblErrorMsg.Text = "";
GridView1.Visible = true;
string str = ConfigurationManager.AppSettings["prink"].ToString();
[Code] .....

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" RowStyle-BackColor="Black" Font-Names = "Arial" Font-Size = "10pt"
HeaderStyle-BackColor="Black" HeaderStyle-ForeColor="Black" ForeColor="Black" AllowPaging ="true"
OnPageIndexChanging = "OnPaging" PageSize = "5">

How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.
View 4 RepliesOn the client I want to instantiate an instance of an entity (that has a datacontract on the server side), send it to the server, let the server modify it in some way, and send it back. I'm talking about using standard-issue, ordinary WCF objects with DataContract/DataMember attributes.
The only way I could figure out to accomplish the above is to pass the object by reference. Is there another way?
In researching this, I found the links below, one of which says it is not possible to pass by ref (yes I realize we are passing a copy, but it is the result I'm interested in. Perhaps that is what the author is alluding to??).
Sorry for having to ask this but I'm confused (again).

i am passing the serverside control as parameter, but it throws OBJECT ERROR.
View 5 RepliesI don't know it happen just to me or Others have the same situation too . All the time when i bind a DataControl to an ObjectDataSource in "Configure Data Source" wizard of ObjectDataSource,when i set parameter source as "Control" in "ControlId" DropdownList there are TWO Item of every control in the WebForm , while it make sense be one.
View 2 RepliesI am playing about just now trying to teach myself a little bit about the entity framework. I have a Gridview data bound to a Entity Date Source using the Entity Framework. If I select certain items in that list I then wish to redirect another page and populate another gridview with just the items selected (but with more detail, different includes/navigation properties)
This is probably the most simple thing but I have spent 2 hours banging my head on the wall trying to get this to work. Essentially I have a continue button which when clicked should identify all the UIDs (a column in the gridview) of the rows and allow me to subset to just these rows and pass them to another page to be rebound to another datagrid
I have a SQLDataSource on an ASP.Net C# page. I want the ability to add a Control Parameter based on a DropDown List that will either display records that are either NULL or Not NULL In a Column. I have the following Code Snippet:

I am binding a control which is inside Gridview, using SqlDataSource control as below.
<asp:ComboBox ID="ddlCompany" runat="server" Height="200" Width="240"
DropDownWidth="310" EmptyMessage="- Select Product -" HighlightTemplatedItems="true" CausesValidation="false"
Filter="Contains" AppendDataBoundItems="true" AllowCustomText="true" AutoPostBack="true"
DataTextField="Title" DataValueField="Code" OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged">
</asp:ComboBox>
[code]....
In above SqlDataSource control, I had to pass the SelectParameter (whose value is coming from a ComboBox i.e., whatever comboBox value I selcect from ComboBox, its SelectedValue I had to pass it to the SqlDataSource SelectParameter. I am first time using "SqlDataSource". How to pass the SelectedValue of ComboBox into SlecteParameter of SqlDataSource control ?
I'm using an entity model with metadata annotations. My controller method looks like this...
if (!ModelState.IsValid)
{
return View(model);
}
else
{
UpdateModel(model);
repo.Save();
return RedirectToAction("Index");
}
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm())
{%>
<%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?

if I debug this I get an error "cannot find the installable ISAM-file", initially I though I may not be using SQL Express, but looking at the SQL Server configuration manager, "SQL Server (SQLEXPRESS) Running", so that isn't the case.
