So I am using EW + Access database to create a page.
This page contains two controls. First control is Dropdownlist which databinds with second control Listview.
This listview has paging on becuse of multiple pages. If I don't use QueryStringField paging works but if I use QueryStringField paging doesn't work and it goes back to first option of Dropdownlist.
I have a listview that I'm binding programmatically. I am trying to add a simple datapager but the paging is not working. it is because I am binding programmatically.

I have this code:
aspx
[Code]....
aspx.cs

Why can I not view anything in my dropdown list? It is totally blank
I have a listview and would like to scroll the ItemTemplatei instead of using paging. I need to freeze the header and InsertTemplate row, and works accross browsers. I've tried the following link:
[URL]
but am having problems getting it to work accross browsers I can get it to work in FF or IE6 but not both.
is there another control rhat's more suitable for this than the ListViiew?
I'm using a datapager control on my listview to perform paging in it.When paging through the table, I need to perform some validations. When these validations are not successfull, the paging should be cancelledI currently perform the validation in the PagePropertiesChanging event of the ListView, however, the arguments do not provide a Cancel property.

I've got a big problem here with the ListView control. Basically I've got very basic code, yet it seems to break the control completely.
Here's the deal, I got a simple ListView using an ItemTemplate containing a hyperlink. Obviously the hyperlink has to lead somewhere after clicking, so the datakeys enter the scene since I need to hook up a hyperlink containing the Id of the record it's in as a parameter.
Normally this shouldn't be a problem, so in the itemcreated event I look up the link control and add the url using data foud in the datakeys.So far so good, this all works out fine.
Now this contains a number of records, too many to display on one page, so I decided to implement paging by using a DataPager, which is the way to get the ListView to support paging. This didn't work.
After a little tinkering around with the code, I found that if I didn't get any datakeys in the itemcreated event, that it all works fine. However, I need to use the datakeys or I won't be able to hook up a url to the hyperlink.
Basically, that one line of code completely kills paging. Commenting it out immediately sets things right, but that's not an option.

If I disable the ViewState on a ListView, the events raised by it are no longer ired. OnPagePropertiesChanging is the ListView event I've always used in combination with the DataPager to update the ListView to the correct page once a DataPager item is clicked, but since its not being fired, I'm wondering if there are any other options. My ListView is currently in an UpdatePanel, and I'm caching the results that the ListView is being bound to. I could rebind the cached results on the PageLoad, but I can't think of a good way to determine if the PageLoad is being accessed because the DataPager was clicked, or for some other reason, so this doesn't seem like a good idea
View 2 RepliesI 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.
so instead of a datasource control, I have a Data Access class that I'm using to populate the ListviewI added a datapager and everything pretty much works until I hit the first or last button. Then, I get the following error: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>Also, Something was mentioned about ClientScriptManager.RegisterForEventValidation - - couldnt' really find an implementationI tried setting:EnableEventValidation="false", but then, all I got was squirelly interaction with all the numbered links (sometimes having to double click them, etc) - no matter what I tried from there on out, even when I removed the enableEventValidation property altogether.
View 7 RepliesI have a question regarding the listview control paging and preserving the state of the items on page change.
I am using listview control and datapager control to achieve paging in the listview control.
I use the listview to display list of questions like with radiobutton list options as answers...
I am unable to preserve the selection of answers between the page changes..
for eg : I If select option1 for the question1 and move to a next page. and If I come back to previous page, the selection goes.
I tried using the view state...but could get this working..
I have a gridview within an updatepanel which allows paging and has a linkbutton that when clicked shows a modalpopup for editing records. This works fine in IE, Firefox, and Opera but I do not get a postback in Chrome or Safari?? I have other linkbuttons on the page that are within updatepanels but are not within gridviews that are working fine. I have scowered the web but cannot find a solution.

View 2 RepliesI was wondering if there were any decent tutorials on paging the records in a ListView using a DataPager (Pager Control). I can get it to work with Drag and Drop but I can't seem to find a decent tutorial on doing it programmatically.

i have a gridview with paging[index 10] enabled on my webpage, now i want a simple dropdownlist in footer or below gridview to have list of no 20,30,40.so that when user selects 20 from it the gridview shows 20 records on same page,when 30 is selected the gridview should show 30 records.i cant figure it out that how to do it, whether it requires coding at database(MYSql) or can be done at the page itself.
View 2 RepliesWhy is the auto paging not working for me? Is that because it only works for BoundField? Mine is mostly
templatefield. Other than auto paging, everything else works fine. I have at least 20 rows, so once I
specify AllowPaging="ture" and PageSize="5", it should give 5 rows a page for 4-5 pages, right?

I published my application into server. Some reason gridview paging is not working when i open the application from the server.
Note: When I ran the application at my local system using VS-2008 it's working fine.
I have a problem with keeping the selected values in DropDownLists in rows in GridView while paging. I have this code behind:
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();
dr["LinijaID"] = LinijaID;
dr["Ime"] = Name;
dt.Rows.Add(dr);
}
}
}
GridView1.AllowPaging = true;
Session["equal1"] = dt;
Response.Redirect("CheckedRowsPage1.aspx");
}
// else
//{
// GridView1.AllowPaging = true;
// Session["equal1"]=null;
// }
}
