I'm binding a dataview to a GridView and am trying to use GridView Paging. When I click on one of the page numbers, the Grid disappears.
Code:

GridView1.AutoGenerateColumns = False

I have a gridview which I load with data on click of a button. For some reason the paging did not work. The paging number shows up but clicking on page # 2, 3 or 4 does not take you anywhere. the grid just disappears on clicking them. right after that when i click the button to generate the grid, the grid came up this time the gird is on page 2 or 3 instead of 1. I have the following on page_indexing properly.

I have the following on page_indexing properly.
Protected Sub GV_Document_Hide_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GV_PSIDocument_Hide.PageIndexChanging
GV_Document_Hide.PageIndex = e.NewPageIndex
End Sub
I even tried by adding the databind() code inside the pageindexchanging as suggested in other threads but that didn't make any difference.
The only way I could get this going was by populating/loading the grid on page_load. I have to assign datasource & databind it every time irrespective of even postbacks. I tried IsNotpostback then the paging failed again Why does gridview needs loading on page_load every time if the paging needs to work properly?

know in asp.net 1.0 the grid display controls would pull all the data in, and then provide paging but the paging was done in memory.Are there any smarter controls that provide paging where they only pull the data relevent to current page being displayed?ie. select 10 rows for the current page, instead of doing a select of ALL the rows in the table.

I have an asp:UpdatePanel in my .aspx page.Within the panel I have placed an infragistics ultrawebgrid control.Upon clicking a button (placed outside the panel) , I have to export the data in the grid to excel.I am using
UltraWebGridExcelExporter(Infragistics object) for this. The export will occur only with full postback.For this I have added a PostBack tigger for the button to the update panel.But once the export is complete, if I change the selected item in a dropdownlist(Autopostback="true") in the same page,the updatepanel gets invisible.

I have a Gridview control with a panel inside a template column and I dynamically add a checkbox control through code to the panel and the checkbox has autopost set. My problem is when I click the checkbox it dissappears on autopost back. I have tried to recreate the control again on the event OnDataBound but when I cast the sender as checkbox I get nothing. How can I not loose my checkbox on postback and why is (Checkbox)sender return nothing.

I'm trying to implement a paging and sorting list in ASP.NET MVC without using MVContrib grid or javascript (needs to be seo friendly). I have constructed my action with the following signature: ActionResult List(int? page, string sort, string direction); The problem I have though is getting both the paging and the sorting to work. Say for example I have the following code: <%= Html.ActionLink("Title", "List", new { sort = "Title", direction = "ASC" }) %> I hoped this would generate a url containing all of the existing route values (including the current page) but it doesn't. Therefore when you click on the link the page is set back to null.
I have looked at all the overloads for the ActionLink helper but nothing looks like it will help. What I effectively need to do is generate a url/link with the existing page value (or potentially any other route values) and the new sort parameters.

The paging is working fine here, the problem is I don't know how it works, because when I put a break point and a logger in the GetCustomers method, I found that parameters maximumRows and startRowIndex are always 0, 0.
I have no clue why StartRowIndexParameterName, and MaximumRowsParameterName are created and how they are used. If they are used in custom mode, so how to enter that mode?

I have an ASP .NET web application. I'm fairly new to .Net but a longtime SQL and Java programmer. I have a requirement to implement a search feature as it is currently implemented in the legacy application. There is a pageable grid of data displayed and a search box. You type your search criteria and the grid pages to the first match. A "next match" button pages to the next item etc. This way the user sees where their search item falls in the hierarchy of the data. I have seen examples where the search criteria filters the data, limiting the data results.

Is there any good solution for ajax enabled Grid with pageing and sorting which only brings the required data from database? I mean it should only bring the data from the database which is to be displayed on the particular page number of the grid.
I looked at this. It looks good. But I just thought if anyone has created something better using Google's or Yahoo's javascript library or using any good features of asp.net 3.5.

<Columns>
<asp:TemplateField HeaderText="Select Student">
<ItemTemplate>
<asp:CheckBox id="Chek" runat="server" Text="select" ></asp:CheckBox>
</ItemTemplate>

I am using grid view control with paging Like-:
protected
void grdUpdateColumn_RowCreated(object
sender, GridViewRowEventArgs
e)
{
if (e.Row.RowType ==
DataControlRowType.Pager)
{
DropDownList ddl
= new
DropDownList();
//adds variants of pager size
ddl.Items.Add(
"5"
);
ddl.Items.Add(
"10"
);
ddl.Items.Add(
"20"
);
ddl.Items.Add(
"50");
ddl.AutoPostBack = true;
//selects item due to the GridView current page size
ListItem
li = ddl.Items.FindByText(grdUpdateColumn.PageSize.ToString());
if (li !=
null
)
ddl.SelectedIndex = ddl.Items.IndexOf(li);
ddl.SelectedIndexChanged +=
new
EventHandler(ddl_SelectedIndexChanged);
//adds dropdownlist in the additional cell to the pager table
Table pagerTable = e.Row.FindControl("pagerTable")as
Table;
//e.Row.Cells[0].Controls[0] as Table;
TableCell cell =
new
TableCell
();
cell.Style[
"padding-left"] =
"15px"
;
cell.Controls.Add(
new
LiteralControl("Page
Size:"
));
}
protected
void ddl_SelectedIndexChanged(object
sender, EventArgs
e)
{
//changes page size
grdUpdateColumn.PageSize = int.Parse(((DropDownList)sender).SelectedValue);
ViewState["Index"]
= 1;
//binds data source
this.GetChangesRecord();
}
Grid view Like -:
<PagerTemplate>
<asp:Table
ID="pagerTable"
runat="server"><asp:TableRow>
</asp:TableRow>
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.

I have been using the GridView control, to display data, but now my two datasources (Informix, and VisualM/Mumps) makes it very difficult to create a store procedure to with paging. Is there a better data grid, that will allow my users to scroll/search the current data set?

I'm migrating a large number of stand-alone pages into content pages. Most of this involves little more than copying and pasting a GridView from one page into the new page. However, I find that styling disappears in the new project, i.e. the styles (as classes) are still present in the stylesheet, but these classes are no longer applied to GridView table elements. Example, in the old project, once a table is rendered by the GridView, its header row has a class of HeaderStyle, but in the new project this is lost, without any editing of the GridView. Is there some mysterious, built-in mechanism that automatically applies these attributes to GridView elements that I have somehow disabled?

I have setup a gridview within an update panel, which resides in a tabcontainer. After I edit any of the rows within the gridview and hit "update" the page reloads and I am no longer able to edit any of the text boxes in the other tabs, and if I attempt to insert or edit a row within the same gridview I'm not able to edit those either. That said, when I hit the tab key a couple of times the cursor appears and I'm able to proceed with editing. Based on the number of times I hit the tab button, it appears that the cursor was inside the textbox I clicked, though it wasn't visible and I simply wasn't able to enter any text.
I've been trying to setFocus on a specific field after any of the grid updates, also tried setting the cursor using ScriptManager.GetCurrent(Me).SetFocus(Me.Control) with no luck.

I have a gridview where in the users are allowed to edit certain data and there is an update on top of the page which will send out all the changes made inside the GridView. But, the problem is , as soon as the update button is clicked, the grid disappearsand no update is made. This problem occurs when the size of the data on the page is huge. When we have less amount of data on the gridview, It does update. But, when there is a huge amount of data on the gridview, it does not. We have tried to increase the page size on the server, but to no use.

On my Form I have 2 gridviews namely; gvCRSearch (that displays search results) and gvCRView (that displays all the change requests raised).. Now, when the records are more than 10 in gvCRSearch it automatically creates a navigation number i.e., 1 2 3 Same thing happens to gvCRView
What is wrong is that when I click the navigation i.e., ( for example 2) on gvCRSearch
1) the gvCrSearch becomes visible = false
2) the gvCRView if it has a navigation number is moved to 2
So the effect is seen the next view (gvCRView) and the gridview (gvCRSearch becomes invisible)
the asp is as shown;
Code:
<asp:GridView ID="gvCRSearchView" runat="server" ShowHeader="True" AutoGenerateColumns="False" DataSourceID="CRSearch"
BackColor="White" BorderColor="#600000" BorderStyle="Solid" BorderWidth="2px" CellPadding="3" Font-Size="89.5%"
ForeColor="Black" GridLines="Vertical" AllowPaging="True" PageSize = "10" AllowSorting ="true" CssClass = "MainGridView">
<Columns>
