Just wondered how to enable/disable "log in" button on a login control based on if User Name and Password textboxes are null or not ?
View 1 RepliesI came to know that we can pass values from one page to another. What I wanted was 'on click of a button on admin.aspx webpage , the button on user.aspx page gets invisible'
After creating the instance and trying to do so, the error occured which said-"due to security the button cannot be accessed on user.aspx from admin.aspx"
Even if all the above what I did was wrong, I request you to suggest me how can I change the property of a button on webform1 from webform2 ( this is the admin.aspx page in which i have logged in) to invisible. And whosoever accesses the webform1 gets the same property (i.e. invisible) untill i click on the button in webform2 that again turns the property of the button in webform1 as visible.
I have several controls on a page that I want to bind the enabled property to a couple of properties in code behind that are set on Page_Load. Here's an example of what I'm using to bind to the properties.
Code:
<telerik:RadComboBox ID="AssignToRadComboBox"
runat="server"
[code]...
This works fine once the page is posted back for the first 4 controls on the page.Here's the 1st control that doesn't get disabled like I expect it to. The expression is the same in the Enabled property so I'm not sure why it isn't working.
Code:
<telerik:RadComboBox ID="CategoryRadComboBox"
runat="server"
Skin="Web20"
Width="225px"
Enabled='<%# IsAdmin && !IsCompleted %>' />
I've got 2 problems with this approach:
1. I need it to happen the first time the page is loaded rather than after a postback.
2. I need it to work for all of the controls on the page having the expression.
It's too late in the development process to rewrite the page so I can't use jQuery & knockoutjs for example to do this all on the client side.
I am having a .aspx page which contains a checkbox,a button and atextbox which is in disable mode.When I check the checkbox then only the textbox need to be enabled.And after enabling if the textbox is empty and when clicked on the button an error msg should be displayed like "Textbox cannot be left empty"and this should be done dynamically.I dont want to add the requiredfield validator during design time instead I want to generate the required field validator when the button is clicked and msg to be displayed.
View 4 RepliesI am having gridview and i have check box for each row. There are 2 buttons ,accept and reject outside the gridview. If I click accept button, all the checked rows fields value should change to accept and if i click reject button all the checked rows column value should change to reject. There are 3 columns only one column will change.
View 1 RepliesI have a radiobutton and if it is checked "Yes", then the three textboxes that are disabled in default will be enable. Now that this textboxes are enabled I want this to be mandatory. How could I do this via javascript or code behind? If I do it in code behind then autopostback is need which is unnecessary.

I want user to be able to scroll in a div to see all the rows. But setting div's overflow property to true. When I starts scrolling header goes away. Is it possible to make header static. So that I can sort or do any kind of other operations.
Currently I tried to take fixed table above grid and hiding grids header. But on editing it is not expanding as the grid is expanding.
i am just trying to change a old project in ASP.Net 2005 to Ajax Enabled Project
how can i do that?
I've inherited a project and in effort to beautify it, I'm replacing an image based menu bar with a CSS based bar. When you click on a button it takes you to the appropriate page.
Currently in the OnInit() it checks what page you're on and then changes the URL of the image for the appropriate button to be the "active" image for that button:
btnFacilities.ImageUrl = "menu_front_facilities.gif";
Pretty simple, and works fine, but it's a pain to add new items, because I need to create a new image and if I want to change the look, I have to create a whole new slew of buttons.
I have built out the CSS menu using basic UL and LI and all the hovers and links work fine. My issue comes when I want to set the "active" item. The way the CSS works is by either setting the CLASS of the active item to "active" or I could easily change it to set the ID of the item to "active", but in either case the viewstate crashes on any posts because the object is not the same as it was when the page loaded, since the style is updated when the OnInit(); event goes off.
I've tried both setting the class name:
menuFacilities.Attributes.Add("class", "active");
as well as directly applying the CSS style:
menuFacilities.Style.Add("background", "#1376c9 url('images/topnav_active.gif') repeat-x;");
Both work fine on the initial page load, but once I click anything that posts, it crashes with a viewstate failure.
If I set the enableviewstate="false" then it works fine between different page loads, but not if I post to the same page (ie submit a search form)
I can't figure out how to handle the "active" object. For some reason the image URL works for asp:Imagebuttons
Here's what one of the items in the menu looks like (pretty simple stuff here):
<li id="menuFacilities" runat="server" ><a href="#">Facilities</a>
<span id="submenuFacilities" runat="server" enableviewstate="false">
I have 1 function that reah all components of the page that call this function.
[Code]....
in this function I set enabled Property of components via parameter "en" but I must cast the object to type manually I want to clear swith statement and change it to 1 line for example: [Code]....
So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?
i want that when a checkbox is checked then it should allow user to write something in a txtbox. initially the txtbox is disabled. what i should write inside the function using jquery

As you can see in the OnPreRender event, the Save button gets enabled or disabled depending on whether the datagrid is in edit mode or not. When I step in the code, it operates correctly in the code, but it does not get reflected correctly on the screen. That is, even when btnSave.Enabled set to true in the code, the browser displays the disabled button. Any idea why this might be happening?
I tried to keep all the data in the gridview when paging, but when I try to save it, which appears in my database only when it is active pages .. ex: in the first and second page I have data in gridview .. when I save, the stored in the database only the first or second page of course .. so I like to keep all my data in gridview when paging..

I have the following code :
Html.CheckBox("creOpsSelected",
new
{id = "creOps"
, value = i.Value})
How do I set the checked property to True when creating the Checkbox
For the life of me I cannot bind the Checked property of a CheckBox control within a TemplateField (declaritively).
I have tried:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="deactivated" runat="server" checked="<%#Eval("Deactivated")%>"></asp:CheckBox>
</ItemTemplate>
<asp:TemplateField>
And
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="deactivated" runat="server" checked="<%#Eval(Container.DataItem, "Deactivated")%>"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
</asp:TemplateField>
I keep seeing a warning stating: Cannot create an object of type 'System.Boolean' from it's string representation' 'for the 'Checked' property.
I have two update panels and in the second update panel i have asp.net button and onclick of the button in codebehind i have disabled it like btnAddSecurity.Enabled = false;
When I disable the button i enable a cancel button before it and on cancel button when i try to enable the btnAddSecurity.Enabled = true it simply doesn't work. Both of my updatepanels updatemode is conditional. what is the problem?
I have a check-box-List which I bind to a master dataTable(DTA)... I have another dataTable (DTB) which has the values that needs to checked in the check-box-List... So I loop through all items in the check-box-list to see if it exists in the DTB and set checked = true for those items that exists. Now I want to show the checked items first in the Check-box-list box and the unchecked items below that. Is there any way I can do it... A similar solution for List-Box could also be helpful. A Javascript hint is welcome too.
View 1 RepliesI think this must be easy... I need to read if a certain checkbox is checked or not, but it's mandatory to me use the findcontrol.Can someone help me ? maybe it's just necessary to complete the code bellow:
Control cb = FindControl(cols[i].id_coluna.ToString());
I used below code fo radiobutton to inserting data in database
string price = RadioButton2.Checked ?"1": "null";
SqlCommand _cmd = new SqlCommand("insertproduct2", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
_cmd.Parameters.AddWithValue("@Price", price);
_cn.Close();
Now I use same code for checkbox I want if users checked chekbox in table insert "1"
else insert "Null" but when I wrote below code
string Off = checkbox1.Checked ? "1" : "null";
it make error Under checked attribute it didn't recognize Checked attribute here. what should i do?
Using CheckBox in DataList to set checked property
View 3 RepliesI have a GridView control that has one column of checkboxes set up like this:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="RowCheckBox" runat="server" Enabled="false" Checked='<%# (bool)DataBinder.Eval(Container.DataItem ,"Associated") %>'/>
</ItemTemplate>
</asp:TemplateField>
Then when the user clicks an Edit button I run a script that enables all the checkboxes (which works fine), and then when the user then clicks on a checkbox the tick is appearing or disappearing as it should.
The problem I'm having is that when I try to read the value of the checkbox from the codebehind:
CheckBox checkBox = (CheckBox) row.FindControl("RowCheckBox");
bool checked = checkBox.Checked;
If the value bound to it was true then checked is still true, no matter if it was toggled or not.
Edit: Corrected a spelling mistake. Question still stands though...
I have a listbox control that is used to insert and update data. There is a checkbox that some users should be able to set while others should not. In what event shold I set it's enabled property and what would the findcontrol string look like?
