I haven't actually dealt with multiple grids on one page in a very long time, so perhaps someone can jog my memory. I have two grids and a treeview in three separate jQuery UI tabs. Every time I page my gridview, which is a custom control inheriting from Gridview, the other tabs refresh.
View 2 RepliesI know practically nothing about AJAX, but fully intended to utilize it in the future. Right now though I am noticing a behavior that may require that I implement it sooner then I planned.
I have been working on a fairily sophesticated web form that is made up of tables, dropdown lists, map buttons, and labels. As various controls are selected, specific tables are enabled or dropdowns/labels populated with information. All of this is working great, but when I put it all on a server and accessed it from a remote location, I noticed that every single action caused the entire page to reload.
From what I have read, it looks like AJAX and the UpdatePanel control will allow me to only refresh those areas that should be refreshed. Before I look further into implementing this, is this the only way to go? From what I have read on some other blogs, the UpdatePanel has some high performance costs.
when i'm on a page, the gridview paging was selected to 2,3, or higher..
the problem is when i reload the page, it goes back to 1 again.. is there any solution to set the selected in gridview paging on every page load?
I haven't worked on the UI in some time. I thought that in ASP.NET 4.0, gridviews handle the paging automatically (if you set paging=true). Is this true, or do you still have to handle it in code?
View 2 Repliesi need to show 3 gridviews in a tab container (ajax).. which should refresh at same time.. what is the optimal way to get data from database for that can some one show a solution for this .
i need to design an application in asp.net using gridview custom control. the gridview will show hundreds of records using paging with checkboxes in every row. if the user checks 3 rows in first page of gridview which is showing 9 rows, those 3 rows should appear on top in the next gridview page and the page should display only 6 new records. ie 6+3=9 similarly if user checks 2 more rows, the next page should show 3+2 rows(from first 2 pages) on top and only 4 new rows ( 3+2+4=9)software developer
before I started working with LinQ I used Objectdatasources to bind a GridView.
To get a label like "item 20 - 30 from 54 items" I used a dataview like this:
Dim dv
As Data.DataView = ObjectDataSource.Select()
Dim count
As
Integer = dv.Count()
Dim first
As
Integer = 1 + (Grid_View.PageSize * Grid_View.PageIndex)
Dim last
As
Integer = first + Grid_View.PageSize - 1
If last > count
Then
last = count
End
If
How can I do this if I bind my GridView with a LinqDataSource?
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.
View 3 RepliesI have a nested gridview containing gridviews: gvMaster(Parent) and gvAlternate(Child)
If I select a row in gvAlternate is there a way for me to find out what gvMaster row it is under? I want to highlight the selected gvAlternate row and the gvMaster row that it is under.
[code]....
I can get a certain set of rows of gvAlternate only by referencing which gvAlternate control set I want to access: this is based on the gvMaster.Rows and then using the FindControl and id name:
GridView
gv = (GridView)this.gvMaster.Rows[aRowNumber].FindControl("gvAlternate");
Therefore, it is true that a set of rows in a nested gridview is tied to a specific row in its master gridview, the question is does the child gridview know which set it's connected to or does it's master know if a childset has been selected?
i have a master details gridview setup, meaning a gridview inside a gridview, but the inner most gridview has a template field hyperlinkbutton control and i set the "CommandName" of the hyperlinkbutton to "Select".
so what i need to do is to get the selected value of the inner most gridview and pass it to a label control which is located outside of the two gridviews.
I plan on having multiple Gridviews on one page populated completely in code behind. The only difference between them will be the Stored Procedure. In an effort to save having to write the following for each gridview, can I reuse the commands for each of them. Below is a sample of one of the commands that I would like to use, as well as the bind sub that I am using.
I realize that it will not be at all difficult to cut and paste each of these lines, and making the minor edits for each one. I just would like to keep my code behind file thin, as well as only limiting the chance for mistakes by using multiple commands.

Actually I already have grid view which show customers list, now i want to add one text box and and button ,customer add category like favorite customer or normal etc and on the basis of this category after button click a new grid view generated on run time which only have same headers like parent grid view but I should be empty,and customer drag the rows from parent grid view to child grid view and after drop on child grid view it should save in data base,,

can I retrieve the name that caused a postback? (VB.NET)
View 5 RepliesCurrently I have two events in my view that can trigger the post back (A dropdownlist and a submit button).
1. <%= Html.DropDownList("List", ViewData["Days"] as SelectList, "--Choose Day--", new { onchange = "this.form.submit();" })%>
2. <input type="submit" value="Submit"/>
When either of these are used, it they both call the [AcceptVerbs(HttpVerbs.Post)] Index() method.
What I want to know is how can I know which event caused the postback, because I need to process each one differently.
I would like to send along the page address that caused a 404 error in my custom 404.aspx file. Is this possible?
I'm using a redirect in the webconfig if a status code of 404 is encountered.
I have an ASP.NET web form application. In the web.config associated with this application, I handle my custom error like so:
<customErrors mode="Off" defaultRedirect="error.aspx" />
When a user gets to the error.aspx page, I want to determine what error caused this page to get reached.
Our client's web app restarts suddenly at random intervals. For each restart, we've found an entry like this in the Windows Event Log:
Event Type: Warning

In Page_Load, Request["__EVENTTARGET"] is an empty string.IS there some way I can find out which button triggered the postback before hitting the buttons event handler
View 2 Repliessender.GetType().Name returns me "default.aspx".How do I get the name or identify the control that caused the page postback (Page_Load() event)?
[Code]....
Is there a way to determine which control on a page caused a post back? I need to be able to make the determination since the _DataBound event of a FormView that I'm working with needs function differently based on which control caused the postback.
View 1 RepliesI have a calendar extender for a text box. I have set the text box 'causesvalidation' to false.
I have several other cntrols with required field validators. When I click the popup image for the calendar extender, rhese other required field validators show their error messages.
Not too sure if the title is the most appropriate description, but I've noticed at the bottom of my page I have a load of 'whitespace' / emptiness where my panel - that is linked to ModalPopup - is during coding / design. Is there a way of this space not appearing when the page is rendered? Setting the panel's visibility to false gives me all sorts of issues and I don't know where to go now to get rid of this annoying space!
