I have a details view that contains a dropdown list
40%
50%
70%
80%
100%
and would like to update the percentage value in the access data table - no problemHowever I would like to also update another field "Saledate" with the current date/time if 100% is selected and if it is subsequently amended from 100% back to any of the others then the field is set to null.I initially though that i could have an update gridview within the detailsview editItemtemplate as per the code below but this fires before the postback on update and therefore would be grateful if someone could let me know how to write the code that will fire on the onupdated event

I have a GridView on a web form, which displays data fetch from database using Linq. When I update the GridView in a button event on server side everything works fine. Now I want to update the GridView from a JavaScript funciton call. Here is the code on the page.
The problem is that GridView1 never gets updated in IE. It works perfectly in Firefox. I can see the event was triggered by the Javascirpt call and I get correct dataset from database through debug. However the GridView never display the correct data. Is GridView handled different from regular web form control?
I have multiple gridviews on one page that connect to the db with different sql datasources.
They each show records with differents "status's"(this is a column in my table). When you update the status on one record I'd like it to display straight away in the other gridview. At the moment I have to reload the page after the update in order to see the changes. Can I set the update buttons in the gridviews to postback after updating?
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
Gridview binding data from database without doing postback on the select of item in dropdown.i know it is possible through ajax update panel but for some specific reason it can't use it.And i think that gridview is a server-side control and if i implement it by using table structure , jquery ajax and web service then it will loose all gridview properties of edit, update and paging etc.
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
Dim iCounter as Integer Dim iQuantity as Integer = 10 Protected Sub btnFoo_Click Handles btnFoo Yadda For i as Integer = iCounter to iQuantity - 1 //do something with AsyncPostBackTrigger until iCounter = iQuantity - 1 //then trigger a full postback Next End Sub
I am new to the concept and feel like there must be something really easy that I am missing.
when postback occurs due to update panel's child control then in page load event how can i know that it was dut to update panel ?i.e., i want to differentiate between general postback and postback due to update panel's child control in page load event .How is that possible ?
Is there any solution to update asp.net gridview without postback and withput update panel? or update partial page without update panel? for example with jquery.
I have a gridview and when i click on the edit button i will get the modalpopup window which is having a popup window i want to update the data in that details view and refresh the data into gridview also.
I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id
the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.
i want to build a datagrid bound to a datatable with several columns. One column has only a dropdownlist with the number of the rows in the datatable.
Here a samplescreenshot:

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?

I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
i got a problem to update my database which i bounded to datagrid. The problem is, i want to update my database only by clicking one update button at the bottom.. when the user click it, all the fields will be updated to database.
I want to update multiple rows of gridview (only price field. for that i have added textbox) on click of update button which is outside of gridview.I have done following way
Up to this its working fine but when no textbox updated then no need to go in for loop so i am looking for confiramtion before updating rows please help me how to do that becausei am less aware with javascript. another problem is textbox value disappear when page index changed how i can retain that values.
When i try to update a row using the update functionality of Gridview it updates all the rows rather then updating that specific row which is in edit mode.
