There is a gridview and I am binding some records to it. in my database there are 4 records but gridview always shows 3 records. Even I have given PageSize 10.
View 4 RepliesI have written a code from here http://www.aspsnippets.com/Articles/Display-GridView-with-Empty-Message-and-Header-and-Footer-when-no-data-in-ASP.Net.aspx. I just edited this as follows. this is my gridview code:-
<asp:GridView ID="gvCustomers" runat="server" Width="550px" AutoGenerateColumns="false"
Font-Names="Arial" Font-Size="11pt" AlternatingRowStyle-BackColor="#C2D69B" HeaderStyle-BackColor="green"
AllowPaging="true" PageSize="10">
<Columns>
<asp:BoundField HeaderText="State Name" DataField="StateName" FooterText="Footer" />
<asp:BoundField HeaderText="Organizatio Name" DataField="OrganizatioName" FooterText="Footer" />
<asp:BoundField HeaderText="Partner Name" DataField="PartnerName" FooterText="Footer" />
</Columns>
<AlternatingRowStyle BackColor="#C2D69B" />
<EmptyDataTemplate>
<table cellspacing="0" rules="all" style="font-family: Arial;
font-size: 11pt; width: 550px; border-collapse: collapse;">
<tr style="background-color: Green;">
<th scope="col">
State Name
</th>
<th scope="col">
Organization Name
</th>
<th scope="col">
Partner Name
</th>
</tr>
<tr>
<td colspan = "3" align = "center">
No Data found.
</td>
</tr>
</table>
</EmptyDataTemplate>
</asp:GridView>
and my code file code is as follows
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["contest"].ConnectionString);
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Bind_Grid();
}
}
protected void Bind_Grid()
{
string strSql = "select * from mtblInformation";
SqlCommand com = new SqlCommand(strSql,con);
SqlDataAdapter sda = new SqlDataAdapter(com);
DataTable dt = new DataTable();
sda.Fill(dt);
if (dt.Rows.Count > 0)
{
gvCustomers.DataSource = dt;
gvCustomers.DataBind();
}
}
when in database table have records then gridview binds and its showing records, But when there is no record in DB , instead of showing msgs that "No Data found." gridview doesn't appear.

I have a question about datalist control. See I only need to display 12 records when the users are viewing in a small preview setting. How can I achieve that? I know I can get TOP 12 from the sql query, but is there a way I can modify in the datalist control itself? DataTable dt = new DataTable();
GridView bound to a SqlDataSource. GridView.AllowPaging is True. In one of the ItemTemplates I have a LinkButton with a OnClick event.Have a DropDownList for changing GridView.PageSize - done in Page_LoadEverything in of-course in an UpdatePanel.
The whole thing work fine (we are in test fase). The problem is that the LinkButton OnClick event is only being attached to the initial "PageSize" amount of elements. Fx. if I sat PageSize=15 in the <asp:GridView> then change the page size to say 30 from the DropDownList, the page size changes but only the first 15 LinkButtons fire the OnClick event when clicked.
I've tried to do the following:
Attached an "onchange" javascript client event for saving the selected value in a <asp:HiddenField> before postback. Problem here is that the HiddenField value is then only available on Page_Load. By then it's too late to set the new page size on the GridView because the attachemnt of events to the LinkButtons have allready happened - of-course only to the first 15 elements.Then I tried to drop the PageSize=15 in the <asp:GridView> and only sat it in the Page_load. The idea was that with no paging all the Linkbuttons will get treated evenly. That worked, but when I change the GridView page size and click fx. on LinkButton 25, the Click event forks fine but the GridView page size resets to the initial value (15) - no good.
how I can get all the LinkButtons to have their event working, even after I change GridView page size?
I have developed a application using Visual Studio 2008 and SQLServer 2008. I have a page called "Billing Center" where i need to display more than 500 records in a gridview and the gridview has sorting enabled. If i limit the page size upto 10 only the gridview performs well but user requirement is to view atleast 500 records at once which is slowing down the gridview record retrieval process.
I am using the following C# code in code behind to sorting, paging and retrieval . Please guide me what am i doing wrong in this code and how to make it work with large data set.

Asp.net gridview dynamic change pagesize not work on the last page.
I have added one dropdownlist in the pager of gridview and add event of selectedIndexChanged with the DropDownList.
Changing pagesize is working except the last page
We can have a look at this link:

I have some doubt about GridView PageSize, for the example if my table have more than 100000 rows and i set PageSize=50, i can see GridView trying to download whole 100000 rows and display only 50 records with pagewise.
In this case my application getting very slow.
Is there anyway to force GridView download data according to the pagesiz without passing limit in sql?

I've been working through the ASP.NET Security Tutorial 12, seen here:
http://www.asp.net/%28S%28pdfrohu0ajmwt445fanvj2r3%29%29/learn/security/tutorial-12-cs.aspx
Part of this tutorial entails setting up a GridView which is bound to the collection of UserAccounts, and then enabling paging on the GridView. There are the usual four links for First, Prev, Next, and Last pages, which should work because I have twelve users defined, and the pagesize of my GridView set to 5. I've set up the code to enable or disable the paging links depending on what section of the entire UserGrid is currently visible.
So when I first run the website and go to the ManageUsers.aspx page, I would expect to see only the first five users in my collection. But it shows all twelve.
I must have overlooked something, but I can't find it in the text and examples.
I have four column in which im getting three column value based on first column the result will be shown from database

View 12 RepliesI'm at an internship fixing this internal system in ASP.NET and C# using VS2008, and I have a gridview that displays purchases, rebate earned, and account number. When I load the page, only the first row of data shows up, and it's always the same values. I sent the output to a label, and my distributor ID and sales amount is the same for the 98 rows. We use MySQL for our database.
Here is my code
[Code]....
[Code]....
distID is always 1224, sales is always 1476.29
I feel like distID should also be in a foreach loop, but I don't how I would do it.
I need to get the selected Pagesize value from the gridview pager.
View 3 Replies how to set the Datapager PageSize programmatically in the code behind (vb)?
here is my datapager asp(.net) code:
[Code]....
When (in what event) is the best time to set PageSize for the ListView's DataPager? I have tried every event on the ListView and either it does not work (i.e., reverts to the default 10) or I get a CRASH of some sort (mostly error 12002) - but that's a different story.
View 6 RepliesUsing VS2005, VB code behind,
I am extending the GridView control to include a custom pager for a custom paging scheme (only one page returned from the database at a time rather than all records). In my testing a discovered an issue - on my last page of data, the GridView's rows property always returns a collection of PageSize page, rather than the actual number of records on the page, with non-data fill records being empty rows.
For example, suppose I have 23 records in my database. Assuming a PageSize of 10, when I page to the last page of data the gridview it properly displays the last 3 recrods - but when I handle the GridView's CommandName="Select" event the GridView's Rows collection contains 10 records, the last seven of which are empty.
I set a break point in just before I call GridView.DataBind and verified that the DataTable used as the DataSource for the last page of data does in fact only contain the 3 expected records. But when I set a breakpoint on the Sub that handles the "Select" GridView command, the GridView.rows collection contains 10 records, the last 7 of which are empty.
This post[URL] and comments make note of the issue but the solution prescribed by the author does not seem to work.
Attached are some snippets of my extended GridView and the two methods from my page where I mentioned setting breakpoints above.

{
DropDownList DStatusEdit = (DropDownList)e.Row.FindControl("DStatusEdit");
string query = "select distinct status from directory";
SqlCommand cmd = new SqlCommand(query);
DStatusEdit.DataSource = GetData(cmd);
[CODE]..

View 1 RepliesI am trying to find out the best method or practice to use a dropdownlist to feed my oracleparameter value. I currently have this working when I have a value selected in the dropdownlist. My issue is how to account for if the user leaves the dropdownlist empty. I want this to then return all data. My SQL has a where clause = to :HRM. I use a function that gets the text for my SQL from a text file. My dropdownlist box is populated via databind. I then inserted a item in my dropdown with 0 index with no text display and a value of "novalue" Below is my code to populate my dropdownlist
[Code]....
[Code]....
If I select an item and run my code it works great. This doesnt work with the no selection tho. Do I have to build the SQL dynamically with a check if the listbox is empty or not and then add the criteria? I was hoping there was a eailer way since I have many queries and parameters to build.
Here is part of my code using the oracleparameter.
[Code]....
I also saw a post about trying this, but I get an illegal error.
[Code]....
Not sure if I can replace the "AND HRM_FIELD = " text and use :HRM instead and then build the oracleparameter with an IIF to include the AND HRM_FIELD part.
I have a gridview that shows all data from a table. DataNames includes KeyId, which is a Primary Key.Yet when I try to delete a record, nothing happens, the page appears to performa refresh but the record is still there.Edit does not work either. I used the wizard to build all of the queries, they look okay. But I cannot figure out why they are not working.

I want to bind only the first 10 records from the dataset to a gridview.how to do this?
View 2 RepliesI would like to display a gridview in which:
I want to create 2 columns and 5 rows and want to give heading to those 2 columns and would like to manually enter the values in the rows, how ? (I don't want to connect this gridview with the database)
Consider the following senario:
1. User sets the records of a gridview to edit mode; that locks all the records of the gridview.
2. Then either session expires or closes the application or browser.
3. All records of the gridview are now locked.
How can we give warning to user or unlock the records.
