Gridview Paging Does Not Work If The Grid Is Not Loaded During Page_load?
Oct 26, 2010
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?
I am trying to create BasePage Web.UI.Page that is inherited by my main page. But when i create public class mypage : BasePage method Page_Load of this class is not loaded in page live cycle. BasePage does not contain any Page_Load. has anybody got a clue where can be the problem?
I am having a gridview with an object datasource binded in the markup(aspx page).When page loads it directly works fine with all sorting and paging properties.However, i need to filter display on gridview so i have to change the datasource of the gridview on the code behindIt works fine.. i mean the filtering and displaying is good but paging and sorting doesnt work.
Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
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 thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?
I have a Page_Load event that writes text to a label to display on the screen: Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)
I also have an On_Click event for a button to display the same information: Output.Text &= "Welcome to my Website <br />"
After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.
I have a GridView inside a ModalPopUpExtender and would like to know how I can ensure that I can work on the grid without the pop up closing everytime i click on say 'edit' or 'delete' on the grid items.
At the minute my pop up is working great, then i click on 'edit' on a row in the grid and it the pop up closes, I then click the button to fire up the pop up again and the grid is in the mode i wanted it to be in!
When Page_Load is running the first time, I set Image 1.jpg to the HTML control with sucess!When Page_Load is running the second time, the Image 2.jpg is Not set to the same HTML control?This even that it should though I use a MessageBox to se that the C# code is running that should set 2.jpg to the control
I am facing serious problem while trying to work in clientevents provided with asp.net mvc telerik grid. Here's the two different scenarios:When I am putting the following script in a view or partial view it works fine;
I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes
a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I haven´t put here.
But what does not work is the code I have in the Page_Load event now.
I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");
This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.
But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve this?
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
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.
In a grid view i have used paging for that i have used the view state to store datatale to bind it on GridView1_PageIndexChanging event every thing works fine but the problem happens with the first column which is having the checkbox placed in each row .On navigation all checked check box becomes unchecked how to maintain the state of check box as well.this is the aaspx code
I have a problem while displaying the data from the grid to the excel.I have implemented pageing and the problem is the page that is displayed is only exported to the excel not all the pages.
