Feb 19, 2011
I have a situation where i have unchecked all checkbox from a panel which havs some nested panels. I am able to clear checkboxes from main panel but nested panel's checkbox remain unchanged. My code is
I have a check box, RequiredFieldValidator and textbox that have editmask extender I want to change the control properties programmatically when I check the check box but the problem that nothing happened when I check it.
I made the control post back and I added triggers.
when put break point and go with code step by step will go through the code but nothing change.
I placed a RadioButtonList inside a Formview control.And from DataBound event handler oformview ,RadioButtonList is binded to the datasource .Now my problem is after selecting a value from radiobuttonlist and I click any button,the radiobuttonList get unchecked and lose the selected value .How can I avoid this.
This code works fine if i use this inside ssercontrol > panel and i have a checkboxes in table when no checkbox is checked its works fine .... but if i disabled and checked any of the textbox then this doesn't work .... in usercontrol why ? i didnt understand ..
<script type="text/javascript" language="javascript"> function checkboxChecked(){ var allInputs = document.getElementsByTagName("input"); for(var i=0; i<allInputs.length; i++) { var chk = allInputs[i]; if(chk.type == "checkbox" && !chk.disabled && chk.checked) {
return true; } } alert("OOps! You haven't selected all available checkboxes"); return false; } </script>
iam developing master page in that master page panel control is there under another panel control is there second panelcontrol is not visiblemy code like that
I have a nested gridview with 45 checkboxes. I want the user to be able to click a checkbox and have that value held in a separate gridview until they wish to act on it (similar to a shopping cart).
The checkboxes are nested in a 2nd level gridview behind a repeater.
I was having a heck of a time trying to get the value of the checkbox that deep and want to learn jQuery and thought this is a good time. What I was thinking was the user would click the checkbox, jQuery would get the id of the control (and value), I could then pass that to a ajax postback trigger and fill the 'shopping cart' gridview. The reason why I need to go through ajax is I need to get more values from a database based on the user selected checkbox. I think I could take it from there. My biggest problem right now is figuring out how to get the id and value from the checkbox.
I need the ability to check a box and then store or remove the text of the checkbox clicked to my sql server database. see my code below that is written in vb.

I am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.
I have a 3 level deep nested gridview. The expansion/contraction of each record was originally done with javascript. There were html <div> tags around each gridview. Since these were HTML div tags I could give them IDs that were dynamically bound to record ID value within the database. I then had onclick buttons that passed in a bound record ID value that coresponded to the appropriate div tag that needed to be expanded (e.g. display: inline (show it) or if it is already inline then display: none).
This worked beautifuly. Unfortunatley I wanted to be able to do in-girdview editing of the child records. When expands a parent record and clicks to edit a child record the OnRowEdit event fires which automatically generates a postback and resets the variables within the JavaScript. THEREFORE THE ENTIRE GRIDVIEW STATE BECOMES CONTRACTED.
So finally I decided to change the div tags to <asp: Panel> and the onclick images to .net clickable images (all .net objects no framework). This works because the state is remembered within each postback. However, the problem I'm having is I can't dynamically bind ID's for panel since this is not allowed. HOW CAN I GIVE THE PANEL <% Bind("id") %>. THAT I CAN REFER TO SO I CAN OPEN THE APPROPRIATE PANEL.
I am using asp.net panel control in which I am adding two controls(a literal that contains some text and a checkbox) in code behind.
The code is something like this....
CheckBox checkBox=new CheckBox(); checkBox.ID = "chk_id"; checkBox.Text = "chk_text"; pnl_cityNames.Controls.Add(checkBox); //add check box pnl_cityNames.Controls.Add(new LiteralControl("Some Text<br>")); //add some text
and to retrieve I am using this code.....
foreach (Control var in pnl_cityNames.Controls) { if (var is CheckBox) { int abc = 0; } }
When I run this code in the debug mood, It shows two added controls
1.)Text="Islamabad" checked=false
2.)System.Web.UI.LiteralControl
This is what the problem I am facing, it should add checkbox in the same manner as LiteralControl. So I am unable to get any condition to be true when I check the var for CheckBox in the foreach loop.
I have a webform that has a formview (fvwContract) and inside itemtemplate there is a Tabcontainer with three tabs (invoice (spanish: factura), receipt (spanish: recibo) and beneficiary (spanish: beneficiario). I have another formview inside invoice tab (fvwFactura) with many textboxes that I need to manipulate in code behind. The thing is that I can´t reference any of them like the following:
I've created a multiple uploadfile user control - upload_multiple_files.ascx:
[Code]....
which has an update panel ID = up_upload_multiple_files this user control will be placed inside a modalpopupextender. My question is when I click in any button AddFile, RemvFile, Upload there's a postback so the page is reloaded and the modalpopupextender disapears Is there a way to to troubleshoot this?
In datalist, I hve populated Grdiview according the Category Id. Inside Gridview , I hve checkboxes. Now i want to get the selected checkboxes names to be insrted into the database. how to get access of those checkboxes inside of Gridview.
I have a RadioButtonList control inside of a nested ListView control InsertTemplate. I need a way to access this control in the nestedListView_ItemInserting method.
I'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
I have a literal inside each datagrid item. When the datagrid binds I set the literal equal to a small javascript script (a third party source). It works great. when I update my update panel the javascript is lost. I know this is a known issue. From googling they recommend you use:
ScriptMananger.RegisterStartupScript
However this renders the javascript at the bottom of the page. I need it inside my datagrid items. Is there a way that I can register my javascript to my literal control?
