I'm trying to change pageindex on page_Load event but its not working. I can change page by clicking links in the page after page loaded.If this info necessary GridView in UpdatePanel.
protected void Page_Load(object sender, EventArgs e) { /*...Some Codes...*/ //I'm trying to change page like this. GridView1.PageIndex = Index; GridViewPageEventArgs ea = new GridViewPageEventArgs(GridView1.PageIndex); GridView1_PageIndexChanging(sender, ea); } protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; }
The FormView is bound to the same ObjectDataSource as the GridView and the FormView uses the autoPaging so I can't just use a separate DataSource for the FormView with just one parameter being the ID.
There must be a way to set the FormView PageIndex by a Datakey value.
I have one textbox one button and one gridview on my webform, when Page loads all records are displayed on gridview, which works perfectly fine, now,I search particular records by entering id in textbox, which finds particular records and found row's background becomes red.which works perfectly fine too, my gridview's pagesize is 15 which means it display 15 records per page, Now,Problem is when i enter ID textbox to search record,but searched record is on another page,so,I want that When i click button to search, the page must be displayed where searched record exist. It displays first page even after search, How can i move to that page where record exist. what i have to code in click event
I just use a FormView to display the data. When I tried to set the PageIndex at Page Load, it is quick to get the PageIndex value from database. But it took 2 seconds to set the PageIndex.
FormView binding to a List collection which get from Database (It is quick to get the data from database)
Each row has a "View Large" link which passes the image id to another page whereupon the image is displayed in a DetailsView.
That page has a "back to album" hyperlink.
All this works nicely, however, no matter what page the user was on in the GridView, having clicked through to the DetailsView and then back to the GridView, the user ends up on page 1 of the GridView.
How can I ensure the user comes back to the same page in the GridView that they were on when they clicked through to the DetailsView? Do I need to pass the gv.PageIndex value and send it back; can I just somehow tell the GridView to "stay where it was"?
Here's the code for the GridView (it pulls the image info from a SQL db:
How do I access GridView Page Index in RowDataBound event? I am assigning PageIndex to hyperlink on the gridview, for this I was planning to use "GridView1.PageIndex" in rowdatabound event. Problem is when I got second page in gridview (10 rows per page), the first row in the page shows page index as "0" and from second row it becomes 1. And if I goto third page, the first row in the page shows page index as "1" and from second row it becomes 2.
I need to get access to the page index of the gridview so I can correctly get some data from a coresponding array to set the cell's contol properties correctly. Below is what I've got so far. The ExcelObject is a class that houses both the data read in from an sutomer submitted excel file and a matching 2 dimensional array of characteristics that I use in this case to set the CssClass property. My problem is that when I enable paging for the gridview I don't get the proper datasource row index when the data is read by the databinder.eval; what I'm getting is the current row of the gridview being generated.
Let me set this up:I have a master page. I have a regular aspx page - this page contains a Menu and a User Control.When I click on the Menu Item, it fires my click event. This will post back. The Master Page Uses Placeholder Controls where I dynamicaly create Label Controls with information and add them to the Placeholders. These contain data with tooltips. This works great. After the Master Page and Web Page load, it will then fire the Click Event from the Menu.The problem:The Click event will update data in the database, This data may effect the values that are created on the Master Page that are placed in the Placeholder controls. I can't seem to figure out how to change that data.
What I have tried:I have created a reference to my Master Page on my Web Page. In the Click Event after I have made changes to the Database, I call the function on the master page that Creates all the data and places them in the place holders. It Runs, but nothing changes on my page.Am I going about this wrong? Is there another way of doing this? I terrible work around, would be to just reload the whole page after I do an update.
I have used Session.SessionID property, but it's keep on changing on every page postback.....can we keep it same untill user sign out from his account..?
I created my page with asp dropdown. On selected index changed I am seeing postback operation on dropdown. I couldn't avoid postback operation of asp dropdown with updatepanel also.
IS there a another way to avoid dropdownpostback operation.
I have a survey, where you have to click through several pages with questions. I use a "Next" and a "Previous" button for doing this. I use a session for keeping tabs on my position. However, this is a problem.
I use the button_click event to increment the page counter, but since this fires after the page_load event, nothing happens on the first click, and for every click thereafter everything is one page behind because the questions are rendered before the counter is incremented.
Is there any way to solve this without using the query-string?

My understanding is that the following happens:
The first page loads and the counter is not set. The counter is set to 1. The first page is displayed. The user clicks the "Next" button, firing a postback. The page loads, displaying the same set of questions, because the counter is still on 1. The buttons Click-event is run, incrementing the counter. However, the page is still displaying the old questions.
After this everything is one page behind because the questions are rendered before the click-event is fired, incrementing the page counter.
what I want to do is when the user enters values on the page I want to be able to change "valueA" and "valueB" in the URL without redirecting, refreshing or posingBack. Does anyone know how to do this?
I have a search page with a TextBox that allows someone to type in a search term and press enter. (Which fires TextChanged). I have a DropDownList that specifies the kind of search that will be performed. It is defined in the markup as follows:
As you can see, AutoPostBack is set to false, and there is no event hookup.
Pressing enter fires the OnTextChanged event for the TextBox, which performs a search and updates a GridView in an UpdatePanel. This UpdatePanel has its UpdateMode set to conditional and has one trigger: the TextChanged event of the search TextBox.
It's very simple.
And it works beautifully, almost.
Whenever I change the search type, the very next search does a full postback. All subsequent searches do partial postbacks (as desired) unless I change the search type again.
There is one exception to this rule: if I load the page and immediately change the search type, it doesn't do a full postback. So the first change of the DropDownList before any postback (full or partial) does not trigger a full postback.
Full Disclosure: I'm doing a lot of JavaScript to change the appearance of the gridview during async requests. I don't detail it here because it seems unrelated. This problem only occurs when a DropDownList with no JavaScript wired up is changed.
I have two dropdownlists on my page that are related to one another, and are built dynamically. I did not write the original code, but I believe it is using AJAX so the whole page doesn't postback when the ddl selection changes. The first ddl is Status and the second is ContractType. Here is the code for the event handler:
I commented out the event handler since this snapshot, just to see what would happen, but when I was hitting it you can see what ex.Message was. I don't understand why it says the SelectedValue is invalid when I see the selected value is "E " and that is one of the four items in the ddl.
I have a question, I have a gridview that shows a red balloon as imagebutton in one of the cells. Now i want to be able to let a users press the button, write a value in a record in the database and then change the red balloon to a yellow one. When the user wants (at any given time) wants the undo the value again the record should be rewriten again and the yellow ballon should be red again. Any tip is more than welcome :)
I have a grid view that I want to dynamically change based on data in my page. Specifically I want to change one of the title items and I want to hide a column based on a certain condition.
I have a DataGrid that is bound to a data set. Down column 1, I need each row in the column to be a link to another page or just plain text - which I can determine post-bind.
I have created a webpage using wizards to set up the objects, can I change the name of all the datasources by just going into the code and entering the new database (the tables are identical) ?ORDo I have to work my way back through all the wizards and re-enter parameters?
I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)
i have a situation, like this, there is a one data grid, which is empty, in that we can add the values, in that grid was paging enabled, so after the 10 record, remaining values ll be in the next page of the grid, so if i want to view that value, i should be use the paging option, here i m getting proble, becz, here i have use the code
