Forms Data Controls :: Post Back From Dropdown In Details View?

Feb 14, 2010

I have 3 drop downs in a details view (populated from a gridview) during insert mode.

Dropdown 1
Dropdown 2 --> Based on drop down one
Dropdown 3 --> Based on drop down two

I am curious of how to handle the autopostback to update 2 and 3 since they are part of the detailsview, there isn't a selected_index_changed event.

I am ok with adding items to them on page load, just not for cascading of them...

AJAX :: How To Do Update Panel And Dynamic Controls And Post Back

Sep 29, 2010

I have a page that is mostly dynamically built in the page load of my VB.net code behind page.

The issue is that I made a change to the page and added a button that redirects to a secondary page. When the button is clicked there is a very noticeable lag until the button click event fires because the page is being rebuilt every time.

I had not wrapped the code in the load event in the If not ispostback.... because I have dynamic controls that the user interacts with and I need the page to be rebuilt when the user clicks them.

The dynamic controls are clickable table cells. I did some looking and I found that the RegisterPostBackControl. I thought this would be perfect but, it does not although I maybe using it incorrectly.

Here is the code flow.

Data Controls :: Add Dynamic Rows In GridView With TextBox And Keep Edited GridView Row Data On Post Back

May 7, 2015

I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .

Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid

Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .

What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .

Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far : 

public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}

[CODE]...

here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...

Forms Data Controls :: Click Button Outside Grid View And Display The Grid View Upon Load?

Feb 9, 2011

I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.

This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:
