I am using asp:menu.In this asp menu,on clicking menu item,I want to get the menuitem,and its parent.I tried to use menuitemclick event.But menuitemclick event is not firing on clicking menu item.
View 1 RepliesI have a fairly complex web app which has two levels of master page. The top level provides a nav bar constructed from a Menu control across the top of the page. Second level master pages provide menus down the side. It all works well.
On both Menu controls, I need to handle the MenuItemClick event. This works fine on the Menu controls on the second-level master pages. However, the Menu on the top level master does not raise the event at all.
This web site makes extensive use of Ajax and the top-level master page contains the ScriptManager. Before I go to all the work of creating a much simpler test site, why the Menu control is not raising the MenuItemClick event?
Here is the markup for the Menu in the top-level master:
[Code]....
Here is the MenuItemClick event handler:
[Code]....
The logging call in the event handler never gets called. Equivalent code in the Menu on the second-level master does get called.
[Code]....
MenuItemClick event will fire on Page1 and Page2 but not Page3 or Page4. The page will post back but will not fire MenuItemClick event. When mouse hovers over the page1 thru page4 nodes IE status bar at bottom shows javascript:__doPostBack('ctl00$Menu1','\/page?.aspx') where ? = 1,2,3,4. I can delete Parent 1 and page1&2 nodes and page3&4 will fire MenuItemClick. Its as though any child nodes after the initial set will not fire the MenuItemClick event.
I want to go to same page by clicking some of my menu items. I am passing the item value(or) text through query string.But my menu's click event is not working. I couldnt get the desired output.
This menu control is in <filename>.master file and event handler is in <filname>.master.cs file.
For reference. My code is below.
protected void TopMenu_MenuItemClick(object sender, MenuEventArgs e)
{
string item = e.Item.Text;
string linkpath = "~/ProductList.aspx?CategoryName=" + item;
Response.Redirect(linkpath);
}
I have a master page, which has a Menu control:
[Code]....
Now I want to "catch" the event when someone click on the new menu item ("Add File"), which will cause a panel in the content page to become visible. I can't catch it in the master page, because then I won't have access to the panel, and I don't know how to catch it in the content page.
I hv created a menu during runtime.. my menu items are from the database. . wen i click the particular menu item, it shud redirect me to the related webpage. .
I wanna know how can i make menuitemclick event fired... nd how can i set different redirect webpages for different menu items as all the menu items r loaded at runtime..
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:

I am using Ext.Net and I have a problem.
I am creating dynamic buttons. It is working but if i click, the button event is not working.:(
My code:
foreach (var events in eventsInformation)
{
Ext.Net.Button btn = new Ext.Net.Button();
btn.ID = events.EvtId.ToString();
btn.Text = events.EvtName;
btn.Click += new EventHandler(Tickets_click);
ViewPort1.Controls.Add(btn);
}
In 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"
></asp:TextBox>
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 2 RepliesI have a div in which i have few text boxes and checkboxes, i wrote checkboxchanged event but it is not firing when i check or uncheck the checkbox i set the autopostback property of the checkbox = true but still no result. does any one have idea how to control this scenario.
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?
