I am having a formview control with paging enabled. It's a simple page used for viewing pictures. (It's from the personal web site starter kit with some modification)
[Code]....
I would like the formview to pass not only the pageindex value but also the Next or previous picture's unique ID called in my case PictureID?

I can display my SessionID in the new (Boxes.aspx) page by using the following:

But I'm sure my code is not correct @ the Eval declarations as I'm getting an error here...?
We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...
I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?

View 2 RepliesI've got a formview that does a simple 'SubTotal' calculation based on some checkbox inputs. I write out the subtotal to an asp:label control. I want to be able to also be able to write that value into the QueryString so I can carry it over to another page. I can't seem to access the label from my codebehind (intellisense doesn't find it). I assume I'm not making the correct reference to the formview label control, but I don't know how to go about getting at it.

I have a master-detail page consisting of a databound GridView and ListView. It's pretty standard - when you select a row in the GridView is shows up the ListView. The problem I'm running into is when I want to link to that page with a specific row pre-selected in both views. It seems like it should be easy enough, but I just can't figure it out. Currently, the ListView is connected to the GridView with a ControlParameter in the SelectCommand.

I am simply trying to get a querystring value and pass it to a textbox in a formview with the default view set to edit mode.

How can I do paging with datalist if that datalist is populated with inputs coming from a querystring?
View 3 RepliesI have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

I have a ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.
I am having troubles making the code run. I have a web page with a gridview and a checkbox. I would like the button when selected to pass the category id. I have managed to get it work without paging. Once the paging kicks in see below, I am unable to run the code. see below.

The new values entered by a user are lost when a error occurs.
I tried to solve this by catching the error in the item updated event as per the code below

however the data in the form gets set back to the original values.
It seams as though the object data source is rebinding the form. How can i determine if this is the case? Is there a way to stop the datasource from rebining?

View 1 RepliesI have Grid view control in the page. Enable paging option is true.
Columns in the Grid view are ID, Name, Checked and Email
Whenever user selects the check box then I am showing txtEmail in the Email columns so that I can enter email id in the textbox.
Like this I am selecting checkboxes and entering values in the txtEmail when I go to next page and comes back. Then these entered values are cleared.
How to keep the textboxes values and checkboxes selected during paging?

private void RememberOldValues()

ArrayList LinijaIDList = new ArrayList();
int index = -1;
foreach (GridViewRow row in GridView1.Rows)
{
index = (int)GridView1.DataKeys[row.RowIndex].Value;
if (Session["equal_ITEMS"] != null)
LinijaIDList = (ArrayList)Session["equal_ITEMS"];
if (row.Cells[0].Text == lineTextBox.Text)
{
if (!LinijaIDList.Contains(index))
LinijaIDList.Add(index);
}
else
LinijaIDList.Remove(index);
}
if (LinijaIDList != null && LinijaIDList.Count > 0)
Session["equal_ITEMS"] = LinijaIDList;
}
protected void Button1_Click(object sender, EventArgs e)
{
//Session["equal_ITEMS"] = null;
RememberOldValues();
GridView1.AllowPaging = false;
BindGrid();
//RePopulateValues();
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("LinijaID", typeof(int)));
dt.Columns.Add(new DataColumn("Ime", typeof(string)));
ArrayList LinijaIDList = (ArrayList)Session["equal_ITEMS"];
//if (LinijaIDList!=null)
//{
foreach (int LinijaID in LinijaIDList)
{
foreach (GridViewRow row in GridView1.Rows)
{
DropDownList Ime = GridView1.FooterRow.FindControl("ImeDropDownList") as DropDownList;
int rowID = (int)GridView1.DataKeys[row.RowIndex].Value;
//string Name = row.Cells[1].Text;
string Name = Ime.SelectedValue;
if (rowID == LinijaID)
{
DataRow dr = dt.NewRow();

dt.Rows.Add(dr);

This is an ASP.NET 3.5 web app written in C# using VS2008 and connecting to an MS SQL backend. It is using ad hoc queries in a strongly typed dataset to pull from the database. This query (shortened for clarity) is designed to allow optional input of parameters (a requirement) or pull all records if no parameters are input. It works normally in SQL Server Management Studio with the addition of Declare and Set statements and it works normally in the TableAdapter's Query Builder:

The markup contains this ObjectDataSource, which is tied to the TableAdapter with the above query:

The problem I'm having is in passing null values to the ODS to feed to the query. Tying the ODS parameters directly to the dropdownlists and textboxes didn't work. Got an error message that there was a mismatched data type. Tried several combinations of code to feed the right values to the ODS parameters but couldn't find one that worked. Is the problem in the query or am I setting up the code-behind wrong? Here's the code:

I have a gridview, which has columns has ChildID,ChildName, course.
In the gridview, i have a radiobutton, which will select one of the rows at a time.I have a button in the page(The button is not related to the gridview). After selecting a row in the gridview, and when the user clicks on the button, i want to pass the data selected in the grid to the button.
The button is used to redirect users to other pages. so i want to use the columns as querystrings to pass to the page. I dont want to use the hyperlinkfield attached to the grid.
Using a class component, an Object data source and a formview I am successfully pulliing data from a SQL database. In some cases the rows contain one or more Null values and I would like them to be ignored completely. My simple code follows:-

<%# Eval("Add_2") & ","%>
<%# Eval("Add_3") & ","%>
