I have a grid view within that i have child gridview,one coloumn of child gridview is bound to check box all thease are in update panel,
i have made checkbox autopostback="true",but check_changed() event is not firing
I in page load i change the checkstate of checkbox false to true or true to false, in turn which i expect to fire the check_change state but seems not firing the event
protected void Page_Load(object sender, EventArgs e)
{
chkDegisim.Checked = true;
chkDegisim.Checked = false;
}
protected void chkDegisim_CheckedChanged(object sender, EventArgs e)
{
int a = 1;
}
when i put a breakpoint to chkDegisim_CheckedChanged, it does not fall into the event chkDegisim_CheckedChanged.
chkDegisim's autopostback is true and i have declered chkDegisim_CheckedChanged event in aspx.
why it does not fire chkDegisim_CheckedChanged event?
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 RepliesI have a page containing a datagrid, which works. On that page I have a button which is supposed to trigger a download of the data from the datagrid in Excel format. However, the button isn't firing the event. The C# code-behind I have is:

View 1 RepliesIn tab container let say I have two tabs [Tab1 & Tab2] Tab1 has 2 text box with required field validator Tab2 has 3 text box with required field validator Now even if I am filling all the text boxes in the TAB1, it is not allowing me to postback. [because TAB2 text boxes are still empty] & When I am filling all the textboxes [Both Tab1 & Tab2], button is firing correctly. I mean user has to fill details for the TAB1 & can submit the details. At that Time I don't want TAB2 validations to work.
View 1 RepliesI've stepped through the code and verified this action. It gets to the end sub and just loops again. Also does it on the production server in IE and Chome (that's all I've tried). Here is the button definition on the actual ASP page:
[Code]....
It goes through the code, sends me an email, gets to End Sub, then loops right back to the top of the sub and goes through the whole thing again, sending me a duplicate email, then exiting normally and sending them to the About page. This is the only code in the aspx.vb besides the class def and inherits statement.
I have a gridview with rows of data and a group of radio buttons for each row that can be selected. But when selected the event never fires for the radio dropdown.... why?
[code]....
when the user comes out of a texbox, i need to read the text entered in the textbox.
I tried using the textchanged event. But it is not firing when i move out of the textbox.
I put a break point at the protected void Page_Load(object sender, EventArgs e) method of my master page, but when i start the site it does not hit that break point.
Why is the event not firing? I would like to use this event along with others such as the Init event in order to check to see if the session has expired everytime a page loads...
I have a GridView, which features a a checkbox on each row (in a template field), where it calls a method upon checked changed (well, when they click submit - no auto post back)
My problem is, the checked change refuses to fire more than once - if I just change the check state of one checkbox in the grid, it works fine. More than one and it only fires the event once.
EDIT: Bit of code:
<asp:CheckBox ID="chkIncludedLocal" runat="server" Checked='<%# Bind("Included") %>'
Enabled="true" OnCheckedChanged="chkIncludedLocal_CheckedChanged" />
And in the event, I put a breakpoint right at the top to see how many times it fires
The OnSelectedIndexChanged event is not firing for my dropdown box. All forums I have looked at told me to add the AutoPostBack="true", but that didn't change the results.

In my web form I have a Textbox control. The TextChanged event of the Textbox is not triggering.
AutoPostBack is set to true What could be the reason for this?Here is the code:
protected void Textr_TextChanged(object sender, System.EventArgs e)

}
<asp:TextBox ID="Textr" TabIndex="10" Style="z-index: 117; left: 500px;
position: absolute; top: 158px" runat="server" Height="22px" Width="180px" MaxLength="50"
AutoPostBack="True" CausesValidation="true" OnTextChanged="Textr_TextChanged"

I have a two web forms with griviews that are bound to SQL through the same query in a class. Both have the same columns and footers. Both have a checkbox control in each grid row. The checkboxes on each form have OnCheckChanged event handlers that I put in the code behind. In fact, the html code is almost the same on both forms, and the OnCheckChanged code is exactly the same except for the fact that I have named them differently. AutoPostBack is true for both checkbox controls in the gridviews. One works, the other doesn't. The difference between the two is that the gridview row checkboxes that don't work are burried in a MultiView. Could that be why the codebehind event handler doesn't fire? Here is the html for the column:

Here is the html for the header of the gridview:

I am having a DataGrid in one usercontrol which is getting filled with some data when I press some button(ouside it). This Datagrid is filled by one linkbutton also. When I click this LinkButton then OnItemCommand or SelectedIndexChanged should fire, but both the events are not firng. While the control's PageLoad event is firing.

View 6 RepliesI have a custom DropDownList control, SDropDownList. I am trying to register and fire the 'SelectedIndexChanged' event. I obviously started by adding the OnSelectedIndexChanged="method" attribute to the markup but it would not fire the event. I also tried registering it programmatically in the OnBound event of the Repeater
protected void rptrSection1_Bound(object sender, RepeaterItemEventArgs e)
{
var ctl = e.Item.FindControl("ddlS1") as SDropDownList;
ctl.SelectedIndexChanged += new EventHandler(ddlS1_SelectedIndexChanged);

I'm using VS 2010, .net 4, vb.net. I have an asp.net site and on a page have 2 drop down lists.
<asp:DropDownList ID="ddlClassIndex" runat="server" AutoPostBack="true" />
<asp:DropDownList ID="ddlClassQBankList" runat="server" AutoPostBack="true" />
When the page first loads i can click on either of these, select an item and the event fires correctly. When i select either of the drop down boxes as a second operation, the first drop down, ddlClassIndex.SelectedIndexChanged fires. What have i done wrong that this would be happening. I do a page.ispostback=false check when the page loads and we are also using master pages.

I am checking for page postback. When i select from the drop down, it redirects to a different page. When i click the back button and selected another value in the other drop down, both SelectedIndexChanged fire. So i do i need to do something with viewstate? before i redired to the other page?
Unusual one this - IE7 and IE8 both behaving, but Firefox isn't. So, I suspect that I have done something wrong which I am "getting away with" in IE.....I have a DynamicPopulateExtender (DPE) and two ModalPopupExtenders (MPE). A Javascript function shows the first MPE (a "please wait" message) and then retrieves the DPE. When the DPE finishes retrieving, its populated event fires - that hides the first MPE and shows the second one which holds the results retrieved by the DPE.I know that I could have used built in functionality within the DPE to display the "please wait" message. However that would mean displaying the MPE before populating the DPE. I can't do that because I want to size the MPE depending on what comes back from the DPE.So, this is my Javascript:
[Code]....
As I said, it works fine in IE7 and IE8. In Firefox (and Opera and Safari), the "please wait" appears and then nothing else happens.

I have spent days looking at different jQuery confirmation box examples but this is the best I can do. Ideally I would want to be use http://jqueryui.com/demos/dialog/#modal-confirmation within gridviews, dataViews and ListViews but can't find examples which exactly provide steps to follow.
I have a ascx like below
<%@
Control
Language="C#"
[code]...
I have an asp.net 2.0 c# site.
In that site, I have a drop down list which allows the user to select from a number of forms with AutoPostBack set to true. I have a OnSelectedIndexChanged event on the dropdown which loads the correct control depending on which option is selected. See below:
[Code]....
Now, that works correctly and loads the form as expected, but the server side onclick event within each ascx control now doesn't work. Is there some problem with button events when controls are added this way? When I add the control in manually to the page it works fine.
