I have a .aspx search screen that displays the results of the search in an asp:GridView component. There can be up to approx 1000 records returned by the search. I want to implememt paging on the grid so that only 15 records are displayed at any one time and the user can page through the results.
I am retrieving the records by passing search parameters to a WCF service which returns a List of particular entity objects. I create a Datatable and insert one DataRow per entity object from the List. I then bind the grid view to the Datatable.
Is there a better way to do this (or am I doing it wrong)? If not, which of the 3 options do you think is the best? I'm leaning towards option 2 as I don't think option 1 is performant and I don't want to be sending loads of unnecessary data back to the browser as per option 3.
I'm experiencing a problem when clicking on the page number within my ASP .NET gridview. When I click another page number, I am redirected to another unrelated page within my project.This wasn't a problem until I added jQuery to my masterpage, so I'm guessing there is some sort of conflict in the javascript code. When the aforementioned redirect happens, the page PageIndexChanging event isn't fired and there isn't a postback as far as I can tell. [code]
I have a simple query: Dim info As New SailMembersDataContext Dim query = From p In info.Individuals GridView1.DataSource = query GridView1.DataBind()
How I can add paging to this query for example 10 on a page I have tried to use the built in paging on the GridView but this just produces the error: The GridView 'GridView1' fired event PageIndexChanging which wasn't handled. When trying to change to another page.
I'm really struggling to make the leap in understanding to get paging working for my gridview. I am creating a web part in vb.net so have programmatically created all the controls. For development I have an aspx page to view my work. I have created a table with code and then inserted my code created gridview. When i enable paging i get the following error.
at System.Web.UI.WebControls.GridView.get_StateFormatter() at System.Web.UI.WebControls.GridView.BuildCallbackArgument(Int32 pageIndex) at System.Web.UI.WebControls.GridView.CreateNumericPager(TableRow row, PagedDataSource pagedDataSource, Boolean addFirstLastPageButtons) at System.Web.UI.WebControls.GridView.InitializePager(GridViewRow row, Int32 columnSpan, [Code] .....
"First, Last, Next, Previous" options to the gridview paging? i can't seem to figure it out. all i can get are numbers and >> for last and << for first...
I am using a standart .net 2.0 Gridview which uses an XMLDatasource to populate the Grid. The Data property of the XMLDatasource is set dynamically which allows the gridview to change based on input.All this works fine however I am having problems with paging.I have set the AllowPaging Property to "true" and set the PageSize Property to "10". The GridView populates fine the first time around showing the first 10 records and the number of pages as hyperlinks at the bottom, BUT when i try to click on any of the page numbers to view them a message box pops up saying "Object reference not set to an instance of an object"..[code]
I am a bit lost in concept how to implement what i want to do. I have a gridview, a checkboxlist. I bind the gridview on the page_load. Everytime user choose a checkboxlist, the gridview rebind as well. I have something like this now. This is not the actual code. Thanks so much.
[Code]....
So what do i put here in order to allow paging ? basically, I have 2 datatables in the above example. In the actual code, I have about 5 datatables with 4 checkboxlists. I can't use Datasource control. I need to do it in codebehind as all code already exists.
Here is the asp code for the design, I have a gridview that lists all Leave dates selected w/ 2 radio buttons . The user may choose if it is for whole day or halfday which are represented by a radio button. I want to get the value of each row if the user wants half day or whole day for me to calculate the leave days.
-I can already get the value but on the first 5 rows only since my gridview is paged with paging size of 5. how can i get the value for the other items if I have more than 5?
i want 2 select data from data gridview and want retrive that data into another form in to the textbox ...is it possible ? i 'm doing like this for that
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.[code...]
I have an asp.net gridview that is originally bound to a sqldatasource control, but when the user presses an external button, it instead gets the contents of a datatable rather than a SQLdatasource control. I therefore had to write code in the PageIndexChanging event of the gridview to allow for paging. My code is as follows:
Protected Sub gvEvents_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvEvents.PageIndexChanging
gvEvents.PageIndex = e.NewPageIndex
gvEvents.DataBind()
This worked beautifully until I added an AJAX update panel so the whole page wouldn't postback every time it paged, and paging stopped working. I debugged it and discovered that it is actually calling the PageIndexChanging event, but nothing is happening. I searched the web and found a few people with the same problem, but their solutions did not work for me. There was one on this site whose problem was solved by the following:
In PageIndexchanging event, where you bind data to grid, make sure, data is again fetched from the DB
I don't know what that means; my data was being bound as demonstrated above. I have "enable paging" set to true and EnableSortingAndPagingCallbacks set to false.
I am including my markup for the updatepanel below.

I am databinding my gridview in VB code behind. Because of this I know I can not refer to the NewValues when text is entered into one of the edit boxes. I need to retrieve the value of a column in the RowUpdating event.I have tried to do this in a multide of ways, but each of my changes ends up breaking something else.None of these three methods is working....
Dim DT34 As String = DirectCast(GridView4.Rows.FindControl("Textbox1"), TextBox).Text
Dim TB1 As Label = GridView4.Rows(e.NewEditIndex).Cells(0).FindControl("Label1")
Dim tb1 As TextBox = GridView4.Rows(e.RowIndex).Cells(0).FindControl("TextBox1") Dim IDVal As String = tb1.Text
In the following code, I am believe it is finding the control but it is not returning the value that was entered into the textbox.
Dim tb As TextBox = DirectCast(GRD4.Rows(index1).FindControl("TextBox1"), TextBox) updateDescription = tb.Text
My field has been converted to a Template field in the Gridview instead of Boundfield.

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
