I have a tabcontainer with 5 tab panels in it. The second tab has two listitems, which require an autopostback, but this then defaults back to the first tab, is there a way it can stay on the same tab?

I have been working on this issue for ever. I did not come to see any solutions for my problem with the gridview autopostback. I have around 10 fields (bound columns) and 1 template field (a checkbox) in my gridview.All the fields should become editable when a user clicks on the "Edit" of the gridview.After that when the user checks or unchecks the checkbox, depending on that two other bound fields should become editable or uneditable.Please help me.My code is as below:
AuctionDates.aspx.cs:

I have two DropDownLists inside an UpdatePanel.
The values shown inside the second are dependent of the selectedValue on the first, so, I need AutoPostBack=true.
But, whenever the selected value in the first DropDownList is changed causes the UpdatePanel reload.
How can this be solved?
PS.: The UpdatePanel's UpdateMode property is set to Conditional.
i duno why, when i put a autopostback in my drop downlist, after the postback, my content HTML editor and the flash button all disappear.
i have put the enable view state = true. but it still happen.
I have an update panel that is triggered by radio buttons. Its pretty straightforward.. show a form if one button it clicked, or another form if another button is clicked. In IE 7, 8, Firefox, etc. this works fine.
In IE6, the radiobutton selection doesnt update the form. If I make a selection, then click the submit button, when the page reloads it will be in it's desired state (meaning the correct form will show). So it's almost like the AutoPostback isnt firing to update the page.
Here's a shortened sample of what Im running into:

In response to @Pabuc below, Im setting the visible property of the table in "Code for Form AB" to true or false depending on the radio button selection.
I have a dropdownlist, and when I set AutoPostBack="true", the page keeps refreshing.
any who knows what might be wrong?

2) Make this click methode works somehow ...
Im making it this way :
B.Click+=EventHandler(fun(_,_) : void { this.LabelCurrentCategory.Text="AAAA"; });
I am using Web expression's aspx form + Microsoft Access database + C# to create a page. I am trying to fire client side script (Javascript) and server side script (Autopostback for databinding) simultaniously without using "Codeback"/"CS".
I am not able to acheive the result. I have read all the 139 pages in trying to find the solution posted in asp.net. I am able to fire client side script (Javascript) but Autopost back is not working and Onselectindexchanged is giving runtime error when I go to publish.
Here is the code.
<form id="form1" runat="server">

I am an asp.net newbie and encountered problem with postback. I have created a web form and put some web controls and set their AutoPostBack property to True.
Some of the controls are listbox, checkbox. However, the SelectedIndexChanged and OnCheckChanged do not fire automatically when an item is selected from the listbox for example or when the checkbox is checked. I noticed that the commands I put in the SelectedIndexChanged and OnCheckChanged is only fired when a button is clicked.
e.g. The code below that sets the text of a label is being fired only when a button is clicked even if the autopostback property of the listbox is set to TRUE.
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ListItem myItem = ListBox1.SelectedItem;
Label1.Text = myItem.Text;
}
Again, I would like the Label's text to change when an item is selected from the listbox and not only when a button is clicked.
What else could I be missing to make autopostback work?
I have a gridview with checkboxes going down the side for each item. Some are enabled and others are not. At the top of the page is a checkbox which when checked will make all the checkboxes on the side enabled. THis is not working and I have tried 2 variations. What am I doing wrong?

I have 5 textboxes in aspx page, and their AutoPostBack property is True. When I write something to first textbox and press tab key to write something to second textbox, the second textbox don't be focused. I have to select second textbox with mouse to write something it. I want to focus the second textbox by pressing tab key after write something to first textbox. HOW Can I do this?
View 6 RepliesI have a page that when auto or partial post back happens, focus is set to the address bar rather than the next control. The interesting thing is that when I put an alert in my RadScriptBlock, after the OK is clicked, focus goes to the correct control -or- if I put in an invalid location, focus is returned to the ExpLocation control & when a correct location is input the second time, the tab order/focus command works correctly (see code below).
That has this up top

I have a code like this

string musisim = DropDownList1.SelectedItem.Value;
SqlCommand cmd = new SqlCommand("select B.HESAP_NO FROM YAZ..MARDATA.S_TEKLIF B WHERE B.MUS_K_ISIM = DropDownList1.SelectedItem.Value", myConnection);
Label1.Text = cmd.ExecuteReader().ToString();
myConnection.Close();
i have a customer name as "MUS_K_ISIM" and his number as "HESAP_NO" All i want is, (autopostback is true) automaticly getting label "HESAP_NO" with who has this number "MUS_K_ISIM" in Dropdownlist. How can i do that?

I have three AJAX sliders and each has a:
<asp:AsyncPostBackTrigger ControlID="Slider1" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="Slider2" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="Slider3" EventName="TextChanged" />
When I do a TextChanged event on slider1 (by dragging the slider, changing the value), the protected void Slider1_TextChanged(object sender, EventArgs e) event FIRES, however, the TWO other sliders, protected void Slider2_TextChange, and protected void
Slider3_TextChange also FIRES. What gives? why do they fire when I am physically only sliding the slider1 across. The two other sliders values did not change on the webform, yet the event fired.
In order for the event to fire for slider1, I had to insert "Autopostback=true" in the <asp:TextBox ID="Slider1" autopostback="true" OnTextChanged="Slider1_TextChanged">. For <asp:TextBox2> and <asp:Textbox3> I did not put the autopostback event for now.
When a user clicks a control that has autopostback=true, the screen refreshes and scrolls back to the top of the page. Is there a way to avoid this and have the page stay in the position it's in?
View 4 RepliesI have an ASP.NET FormView within an updatepanel. I'm auto-saving the form by setting AutoPostBack=true for each of the items within the FormView.
This means the user can click a few elements in quick succession and fire off a few async postbacks almost simultaneously.
The issue I have is that the user is able to keep scrolling down the form while the async postbacks are not yet complete. The browser always scrolls back to the position it was in at the first postback.
Page.MaintainScrollPositionOnPostback is set to False.

Iam trying to use System.Web.UI.WebControls.Calender. But when I select any date , It post backs automatically. Is there any way to avoid this behavior.

View 2 RepliesIs there a way to have a textbox autopostback when the 5th character is entered into the textbox?
I have a zipcode textbox that I would like to fire an autopostback as soon as the 5th character is entered. Currently I have it so it will fire when tabbed out of or when the next textbox is clicked in but it would save one step for the customer if it fires on the fifth character.

can you define autopostback and postback and it's differences and which web server control support autopostback and postback and also the difference between postback and callback?
View 3 RepliesI have a webform with multiple input textboxes. each box is used in computing somethings, and i am doing these calculations within the TextChanged event for each textbox...this way after the user enters each entry, all calculations requiring that data is performed. I have also set EnableViewState="true" and AutoPostBack="true" cause I am trying to have the textbox keep their data displaying on AutoPostBack. The form is not behaving the way I want it to...right now, if a user inputs data in one field and switches focus to the next, the previous box losses it's data. Is there a way i can get this behaving the right way? I basically just want all the controls to keep their data on AutoPostback.

I have created a custom control in ASP.net which includes a DropDownList with AutoPostBack set to true. I have also attached an event SelectedIndexChanged for the control.But I find that the event is not fired. Where as normal asp.net DropDownList with AutoPostBack set to true will fire the event.

The app is written in c# but i havn't posted any actual code as all the user code related to this markup seems to work fine.
The problem is the CheckBox chkTVLic has causes validation set to false and autopostback set to true. So whatever happens when i check and uncheck the checkbox it should postback. Most of the time this is exactly what it does and the result is to show and hide pnlTVLic when it is checked and unchecked. However if any on the validators within the panel fire, the checkbox does not cause a postback the first time. It will on all subsequent times but never the first. However it should ALWAYS cause a postback. What could be stopping it. Before someone asks there is no use written client side code, everything is pure .net markup and c# code.
